Online ratings and narrative comments of American Head and Neck Society surgeons

BACKGROUND

We analyzed online rating scores and comments of head and neck surgeons to understand factors that contribute to higher ratings.

METHODS

Numerical ratings and comments for American Head and Neck Society physicians were extracted from Healthgrades, Vitals, RateMDs, and Yelp, with narrative comments categorized based on content. Physician practice location, education, and residency training were also compiled.

RESULTS

Patient ratings were significantly higher with supportive staff and affable physician demeanor but showed significant drops with longer wait times and difficulties scheduling appointments or follow-ups. Physician education and postgraduate training did not significantly affect ratings.

CONCLUSION

Online ratings and comments correlated to modifiable factors in clinical practice and may be informative in understanding patient needs.

Assessment of laryngologists' ratings on physician review websites

Objective

To assess and characterize online ratings and comments on laryngologists and determine factors that correlate with higher ratings.

Methods

All the American Laryngological Association (ALA) members were queried across several online platforms. Ratings were normalized for comparison on a five-point Likert scale. Ratings were categorized based on context and for positive/negative aspects.

Results

Of the 331 ALA members, 256 (77%) were rated on at least one online platform. Across all platforms, the average overall rating was 4.39 ± 0.61 (range: 1.00-5.00). Specific positive ratings including "bedside manners," "diagnostic accuracy," "adequate time spent with patient," "appropriate follow-up," and "physician timeliness" had significant positive correlations to overall ratings, by Pearson's correlation (P < 0.001). Long wait times had significant negative correlations to overall ratings (P < 0.001).

Conclusion

Online ratings and comments for laryngologists are significantly influenced by patient perceptions of bedside manner, physician competence, and time spent with the patient.

A Novel Technique of Reduction Meatoplasty for Correction of Very Large Meatus from a Previous Canal Wall-Down Mastoidectomy

OBJECTIVE

To evaluate the efficacy of reduction meatoplasty, a novel technique aiming to improve the usage of molded hearing aids and ear plugs in patients undergoing mastoid obliteration of a previous canal wall-down (CWD) mastoidectomy, complicated with a very large meatus.

PATIENTS

Twenty-six patients from a tertiary care neurotology clinic with a very large meatus from a previous CWD mastoidectomy, who were unable to use molded hearing aids or ear plugs for water protection.

INTERVENTION

Reduction meatoplasty after mastoid obliteration (cartilage strips and bone pate) of the CWD mastoidectomy. The procedure involves removing a wedge of skin and underlying soft tissue superiorly in the meatus.

MAIN OUTCOME MEASURES

Reduction in meatus size, enabling usage of hearing aids and ear plugs.

RESULTS

Twenty-six patients underwent mastoid obliteration and reduction meatoplasty to reduce meatus size. Patients were followed up for an average of 22 months postoperation. After operation, the meatus size was significantly reduced in all patients, enabling usage of over-the-counter ear plugs. In addition, all six patients with hearing aids could use standard occlusive hearing aid domes without requiring molded hearing aids. No patients showed symptoms of chronic infection in the mastoid cavity during the follow-up period.

CONCLUSIONS

Results of reduction meatoplasty showed significant improvements in functionality of the external auditory meatus, indicating that this technique is effective in reducing meatus size and improving the normal meatal anatomy after mastoid obliteration.

Meniere's disease is a manifestation of migraine

PURPOSE OF REVIEW

To discuss the theory that Meniere's disease (MD) is a variation of otologic migraine rather than an isolated inner ear condition.

RECENT FINDINGS

In contrast to the approximately 12% of the general population suffering from migraine headaches, 51-60% of patients with MD experience migraine headaches. While pathognomonic for MD, endolymphatic hydrops has also been identified in patients with vestibular migraine. Treatment with the integrative neurosensory rehabilitation approach (diet and lifestyle changes, magnesium and riboflavin supplementation, and when needed, prophylactic medication) to treat the underlying migraine process has been highly effective in patients with MD.

SUMMARY

MD can be understood as a manifestation of migraine such that patients with MD can be effectively treated with migraine therapies.

Triamcinolone Injection for Cochlear Implant Magnet Adherence Issues

OBJECTIVES

To evaluate the effectiveness of triamcinolone injections in treating external magnet displacement in cochlear implant (CI) patients with adhesions problems of their processor.

PATIENTS

We present seven CI patients with magnet adhesion issues who presented to our tertiary care neurotology clinic. None of the patients had a history of head trauma, postimplant MRI, or surgery in the head and neck other than the cochlear implantation.

INTERVENTION

Triamcinolone 40 mg/mL injected subcutaneously at the CI magnet site.

MAIN OUTCOME MEASURE

Reduction of scalp thickness and successful magnet retention.

RESULTS

Our cohort consisted of seven patients (eight implant sites) of which five were overweight or obese. The temporoparietal scalp thickness measured on preoperative CT scans varied between 8.4 and 15.9 mm. Initial conservative measures such as hair shaving at the magnet site, using a headband, and increasing magnet strength failed in all patients. After receiving triamcinolone injections at the CI receiver site, six out of seven patients (seven out of eight CI sites) were able to use their processor again without the need for a headband for an average of 9.55 hours/day. The average number of injections required for each patient was 2.57 (SD = 2.18), median (range) = 1 (1-7). One patient required a flap thinning surgery but showed no improvement even after flap thinning. None of the patients showed skin irritation, breakdown, ulceration, necrosis, or magnet exposure during follow-up period.

CONCLUSIONS

The significant improvement in CI retention shows that triamcinolone injections are effective in making the subcutaneous tissue thinner and allowing magnet retention.

Management of Migraine-Associated Vestibulocochlear Disorders

Migraine is a chronic neurological disorder that frequently coexists with different vestibular and cochlear symptoms (sudden hearing loss, tinnitus, otalgia, aural fullness, hyperacusis, dizziness, imbalance, and vertigo) and disorders (recurrent benign positional vertigo, persistent postural perceptual dizziness, mal de debarquement, and Menière's disease). Despite evidence of an epidemiological association and similar pathophysiology between migraine and these vestibulocochlear disorders, patients suffering from migraine-related symptoms are usually underdiagnosed and undertreated. Current migraine treatment options have shown success in treating vestibulocochlear symptoms. Lifestyle and dietary modifications (reducing stress, restful sleep, avoiding migraine dietary triggers, and avoiding starvation and dehydration) and supplements (vitamin B2 and magnesium) offer effective first-line treatments. Treatment with migraine prophylactic medications such as tricyclic antidepressants (e.g., nortriptyline), anticonvulsants (e.g., topiramate), and calcium channel blockers (e.g., verapamil) is implemented when lifestyle and dietary modifications are not sufficient in improving a patient's symptoms. We have included an algorithm that outlines a suggested approach for addressing these symptoms, taking into account our clinical observations. Greater recognition and understanding of migraine and its related vestibular and cochlear symptoms are needed to ensure the appropriate diagnosis and treatment of affected patients.

Correlation Between Laterality of Hearing Loss and Migraine Features in Menière's Disease

OBJECTIVES

The objective of this study is to understand whether the hearing loss laterality in Menière's disease (MD) correlates with migraine symptoms laterality such as headache, neck stiffness, and otalgia.

METHODS

We performed a retrospective review of prospectively obtained data on patients presenting between September 2015 and October 2021 with definite or probable MD. A custom-designed, comprehensive questionnaire was used to identify patients' migraine-related symptoms. The clinical and audiometric data were used to diagnose patients with definite or probable MD using criteria set by the American Academy of Otolaryngology-Head and Neck Surgery.

RESULTS

In total, 113 patients with definite or probable MD were included in the study. The mean age of the patients was 60 ± 15 years with no gender predominance (49.6% male and 50.4% female). A total of 57 (50%) patients were presented with headaches. Among the migraine headache cohort, headache and otalgia were on the same side as the MD ear affected by hearing loss. In addition, in patients who present with otalgia as the primary feature of headache, otalgia was more likely to be on the same side as the ear affected by the hearing loss.

CONCLUSIONS

The high prevalence of migraine symptoms on the same side of the ear affected by MD among this cohort could suggest a shared pathophysiology in both MD and migraine, possibly involving migraine-related changes in both the cochlea and vestibule.

Artificial neural network prediction of post-thyroidectomy outcome

OBJECTIVES

The goal of this study was to develop a deep neural network (DNN) for predicting surgical/medical complications and unplanned reoperations following thyroidectomy.

DESIGN, SETTING, AND PARTICIPANTS

The 2005-2017 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried to extract patients who underwent thyroidectomy. A DNN consisting of 10 layers was developed with an 80:20 breakdown for training and testing.

MAIN OUTCOME MEASURES

Three primary outcomes of interest, including occurrence of surgical complications, medical complications, and unplanned reoperation were predicted.

RESULTS

Of the 21 550 patients who underwent thyroidectomy, medical complications, surgical complications and reoperation occurred in 1723 (8.0%), 943 (4.38%) and 2448 (11.36%) patients, respectively. The DNN performed with an area under the curve of receiver operating characteristics of .783 (medical complications), .709 (surgical complications) and .703 (reoperations). Accuracy, specificity and negative predictive values of the model for all outcome variables ranged 78.2%-97.2%, while sensitivity and positive predictive values ranged 11.6%-62.5%. Variables with high permutation importance included sex, inpatient versus outpatient and American Society of Anesthesiologists class.

CONCLUSIONS

We predicted surgical/medical complications and unplanned reoperation following thyroidectomy via development of a well-performing ML algorithm. We have also developed a web-based application available on mobile devices to demonstrate the predictive capacity of our models in real time.

Treatment of Stapedial Myoclonus as a Migraine-Related Phenomenon

OBJECTIVE

To describe a case series of patients with stapedial myoclonus (SM) whose conditions improved after prophylactic migraine treatment.

PATIENTS

We present seven cases of SM reported from a tertiary care neurotology clinic. All seven patients reported SM triggers similar to those of migraine headaches and suffered from concomitant headaches and/or vertigo, and were thus treated with a standard migraine protocol used at this neurotology clinic.

INTERVENTION

Prophylactic migraine treatment.

MAIN OUTCOME MEASURES

Reduction or resolution of SM.

RESULTS

In this series, seven patients with SM were included. Six of seven subjects were male (86%), with a mean age at presentation of 44 years. Four patients noted significant improvement in their symptoms, with a reduced frequency, duration, and intensity of their symptoms with the migraine regimen. Three patients experienced complete resolution of SM with their migraine treatment.

CONCLUSION

We report that treatment with prophylactic migraine treatment can provide long-term relief for patients with SM, which may suggest an etiological association between migraine and SM as well as a possible treatment for SM.

One hundred most-cited articles in head and neck surgery and analysis of female authorship

BACKGROUND

While female head and neck surgeons have made significant contributions to the field, women's achievements in scientific communication have traditionally been underreported.

METHODS

A search of high-impact journals in the field of head and neck surgery was performed in the Elsevier's Scopus database to identify the top 100 most-cited articles.

RESULTS

The top 100 most-cited articles (during the span of 1953 and 2016) had the highest total number of citations between 2005 and 2009. Women accounted for 36% of first authors and 25% of corresponding authors. Change in the relative number of first female authors in these top 100 articles did not increase significantly between 1950 and 2019.

CONCLUSION

The proportion of female first authors in head and neck surgery has not significantly increased over the past several decades, despite greater numbers of female trainees. Our findings support the need for additional research on female representation in head and neck surgery.

Tympanostomy tube placement for pressure-sensitive vertigo

Objective

To evaluate tympanostomy tube placement in patients with pressure-sensitive vertigo.

Methods

Retrospective case series.

Results

Six patients with pressure-sensitive vertigo reported resolution of their vertigo and other vestibular symptoms after placement of the tympanostomy tubes. All recurrences of symptoms were due to either extrusion or plugging of the tubes. All patients fulfilled the criteria for vestibular migraine. None of the patients had superior canal dehiscence on imaging or precedent event that triggered the problem, and all had a negative fistula test.

Conclusion

Tympanostomy tube placement should be considered in selected patients with vertigo exacerbated by seemingly small changes in atmospheric pressure (e.g., just prior to thunderstorms, air travel, or travel to the mountains). By eliminating the capability of the tympanic membrane to sense changes in pressure with a tube, patients with pressure-induced vertigo (in the absence of perilymph fistula or superior canal dehiscence) may have relief of their symptoms.

Level of Evidence IV

Migrainous Vertigo, Tinnitus, and Ear Symptoms and Alternatives

Migraine headaches frequently coexist with vestibular symptoms such as vertigo, motion sickness, and gait instability. Migraine-related vasospasm can also damage the inner ear, which results in symptoms such as sudden sensorineural hearing loss and resultant tinnitus. The pathophysiology of these symptoms is not yet fully understood, and despite their prevalence, there is no universally approved management. This review summarizes the data on complementary and integrative medicine in treating patients with migrainous ear disorders.

A Comparison of Near-Infrared Imaging and Computerized Tomography Scan for Detecting Maxillary Sinusitis

OBJECTIVE

To investigate the use of near-infrared (NIR) imaging as a tool for outpatient clinicians to quickly and accurately assess for maxillary sinusitis and to characterize its accuracy compared to computerized tomography (CT) scan.

METHODS

In a prospective investigational study, NIR and CT images from 65 patients who presented to a tertiary care rhinology clinic were compared to determine the sensitivity and specificity of NIR as an imaging modality.

RESULTS

The sensitivity and specificity of NIR imaging in distinguishing normal versus maxillary sinus disease was found to be 90% and 84%, normal versus mild maxillary sinus disease to be 76% and 91%, and mild versus severe maxillary sinus disease to be 96% and 81%, respectively. The average pixel intensity was also calculated and compared to the modified Lund-Mackay scores from CT scans to assess the ability of NIR imaging to stratify the severity of maxillary sinus disease. Average pixel intensity over a region of interest was significantly different (P < .001) between normal, mild, and severe disease, as well as when comparing normal versus mild (P < .001, 95% CI 42.22-105.39), normal versus severe (P < .001, 95% CI 119.43-174.14), and mild versus severe (P < .001, 95% CI 41.39-104.56) maxillary sinus disease.

CONCLUSION

Based on this data, NIR shows promise as a tool for identifying patients with potential maxillary sinus disease as well as providing information on severity of disease that may guide administration of appropriate treatments.

Otolaryngology residency programs' perspectives on virtual interviews during the COVID ‐19 pandemic

Objective

To evaluate perceptions of otolaryngology residency program directors (PDs) and department chairs (DCs) on virtual interviews (VIs) at the conclusion of the 2021 residency match.

Study design

Cross‐sectional survey study.

Methods

An anonymous and voluntary survey was administered to PDs and DCs of U.S. otolaryngology residency programs from March 1, 2021 to April 11, 2021. Utilizing Likert scale ratings, the survey measured overall satisfaction with the VI format, perceived ability to assess key candidate attributes, relative importance of traditional candidate metrics, and likelihood to implement VIs in future cycles.

Results

Ninety‐four surveys were completed by PDs (48.9%) and DCs (51.1%). Sixty (63.8%) respondents found the VI experience to be satisfactory or strongly satisfactory. Sixty‐six (70.2%) respondents felt confident in their ability to assess a candidate's professionalism and communication skills through VIs; however, confidence in gauging an applicant's clinical skills/knowledge (41.2%) and overall program fit (47.3%) was lower. Regarding candidate metrics, 64 (68.1%) respondents believed that personal prior knowledge of the applicant gained increased importance with VIs. Forty‐four (46.8%) and 45 (47.9%) participants believed that letters of recommendation in the specialty and perceived commitment to their program similarly attained increased significance in evaluating applicants, respectively.

Conclusion

Most PDs and DCs were satisfied with their VI experiences and expect the quality of interns to be unaffected by virtual assessment modalities. Majority opinion on the relative importance of traditional applicant metrics remained largely unchanged, the exception being an increase in importance of prior knowledge of the applicant.

Vestibular and auditory manifestations of migraine

PURPOSE OF REVIEW

The purpose of this narrative review is to discuss current literature about vestibular migraine and other cochleovestibular symptoms related to migraine.

RECENT FINDINGS

Vestibular migraine affects 2.7% of the US population. Misdiagnosis is common. The pathophysiology is currently unknown but new research shows that calcitonin gene-related peptide, which is implicated in migraine headaches, is expressed in the audiovestibular periphery. A recent large-scale placebo-controlled trial looking at metoprolol for vestibular migraine was terminated early due to poor recruitment; however, at study completion, no differences were seen between treatment arms. Many other audiovestibular symptoms have been shown to be associated with migraine, including tinnitus, hearing loss, aural fullness, otalgia, and sinus symptoms. Migraine is also associated with risk for developing numerous otologic conditions, including Meniere's disease, vestibular loss, Benign Paroxysmal Positional Vertigo, and sudden sensorineural hearing loss. There is now some evidence that patients may experience fluctuating hearing loss and aural fullness without vertigo in association with migraine, which is called cochlear migraine.

SUMMARY

Migraine can cause a variety of audiologic and vestibular symptoms, and further research is required to understand how migraine affects the inner ear.

Care Gaps and Recommendations in Vestibular Migraine: An Expert Panel Summit

Vestibular migraine (VM) is an increasingly recognized pathology yet remains as an underdiagnosed cause of vestibular disorders. While current diagnostic criteria are codified in the 2012 Barany Society document and included in the third edition of the international classification of headache disorders, the pathophysiology of this disorder is still elusive. The Association for Migraine Disorders hosted a multidisciplinary, international expert workshop in October 2020 and identified seven current care gaps that the scientific community needs to resolve, including a better understanding of the range of symptoms and phenotypes of VM, the lack of a diagnostic marker, a better understanding of pathophysiologic mechanisms, as well as the lack of clear recommendations for interventions (nonpharmacologic and pharmacologic) and finally, the need for specific outcome measures that will guide clinicians as well as research into the efficacy of interventions. The expert group issued several recommendations to address those areas including establishing a global VM registry, creating an improved diagnostic algorithm using available vestibular tests as well as others that are in development, conducting appropriate trials of high quality to validate current clinically available treatment and fostering collaborative efforts to elucidate the pathophysiologic mechanisms underlying VM, specifically the role of the trigemino-vascular pathways.

Migraine Features in Patients With Isolated Aural Fullness and Proposal for a New Diagnosis

OBJECTIVE

To compare the presence of migraine features between patients with isolated aural fullness (AF) who meet the diagnostic criteria for migraine headache and those who do not, and to propose diagnostic criteria for migraine-related AF based on our results.

METHODS

We performed a retrospective study of patients presenting to a tertiary-care neurotology clinic between 2014 and 2020 with migraine-related AF. This was defined as isolated, prolonged aural fullness concurrent with migraine features once other etiologies were ruled out via examination, audiometry, and imaging. Migraine features were compared between patients meeting the diagnostic criteria for migraine headache and those not meeting the criteria.

RESULTS

Seventy-seven patients with migraine-related AF were included. The mean age was 56 ± 15 years and 55 (71%) patients were female. Eleven (14%) patients fulfilled the criteria for migraine headache (migraine group). Of the 66 patients who did not meet the criteria (nonmigraine group), 17 (26%) met 4/5 criteria, and 32 (48%) met 3/5 criteria, for a total of 49 (74%) patients. The migraine and nonmigraine groups were only different in 5 of 20 features, including family history of migraine (p = 0.007), sound sensitivity (p < 0.001), mental fogginess (p = 0.008), visual motion sensitivity (p = 0.008), and light sensitivity (p < 0.001).

CONCLUSION

There are minimal differences in the overall prevalence of migraine features between patients with migraine-related AF who meet and do not meet the diagnostic criteria for migraine. Our findings suggest that the criteria may be too stringent and exclude many patients from potentially benefitting from treatment with migraine prophylaxis.

A Web-Based Deep Learning Model for Automated Diagnosis of Otoscopic Images

OBJECTIVES

To develop a multiclass-classifier deep learning model and website for distinguishing tympanic membrane (TM) pathologies based on otoscopic images.

METHODS

An otoscopic image database developed by utilizing publicly available online images and open databases was assessed by convolutional neural network (CNN) models including ResNet-50, Inception-V3, Inception-Resnet-V2, and MobileNetV2. Training and testing were conducted with a 75:25 breakdown. Area under the curve of receiver operating characteristics (AUC-ROC), accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were used to compare different CNN models' performances in classifying TM images.

RESULTS

Our database included 400 images, organized into normal (n = 196) and abnormal classes (n = 204), including acute otitis media (n = 116), otitis externa (n = 44), chronic suppurative otitis media (n = 23), and cerumen impaction (n = 21). For binary classification between normal versus abnormal TM, the best performing model had average AUC-ROC of 0.902 (MobileNetV2), followed by 0.745 (Inception-Resnet-V2), 0.731 (ResNet-50), and 0.636 (Inception-V3). Accuracy ranged between 0.73-0.77, sensitivity 0.72-0.88, specificity 0.58-0.84, PPV 0.68-0.81, and NPV 0.73-0.83. Macro-AUC-ROC for MobileNetV2 based multiclass-classifier was 0.91, with accuracy of 66%. Binary and multiclass-classifier models based on MobileNetV2 were loaded onto a publicly accessible and user-friendly website (https://headneckml.com/tympanic). This allows the readership to upload TM images for real-time predictions using the developed algorithms.

CONCLUSIONS

Novel CNN algorithms were developed with high AUC-ROCs for differentiating between various TM pathologies. This was further deployed as a proof-of-concept publicly accessible website for real-time predictions.

Tinnitus and Subjective Hearing Loss are More Common in Migraine: A Cross-Sectional NHANES Analysis

OBJECTIVES

To investigate whether migraine is independently associated with tinnitus and subjective hearing loss (HL) in a large national database.

METHODS

The de-identified 1999 to 2004 National Health and Nutrition Examination Survey database was retrospectively queried for subjects aged 18 to 65. HL and tinnitus were subjectively reported by subjects.

RESULTS

A total of 12,962 subjects (52.9% female) with a mean age of 38.1 ± 14.6 years were included. This consisted of 2,657 (20.5%), 2,344 (18.1%), and 2,582 (19.9%) subjects who had migraine, subjective-HL, and tinnitus, respectively. In patients with tinnitus or subjective-HL, migraine was reported in 35.6% and 24.5%, respectively. Migraineurs were more likely to have subjective-HL (25.0% vs. 16.6%, p < 0.001) and tinnitus (34.6% vs. 16.9%, p < 0.001) compared to the nonmigraineurs. This corresponded to migraine having an odds ratio of 1.5 (95% confidence interval [CI] 1.3-1.7, p < 0.001) and 2.2 (95% CI 2.0-2.4, p < 0.001) for subjective-HL and tinnitus, respectively. After adjusting for confounders, subjective-HL (odds ratio [OR] = 1.2, 95% CI 1.1-1.4, p = 0.003), tinnitus (OR = 2.1, 95% CI 1.9-2.3, p < 0.001), and neck pain (OR = 4.0, 95% CI 3.6-4.5, p < 0.001) were more common in migraineurs. Among migraineurs, a higher proportion of those with tinnitus also had subjective-HL compared to those without tinnitus (40.0% vs. 15.3%, p < 0.001), and a higher proportion of those with subjective-HL also had tinnitus compared to those without HL (58.1% vs. 27.3%, p < 0.001).

CONCLUSIONS

This study suggests an independent association between migraine with subjective-HL and tinnitus. Otologic migraine, which is the effects of migraine on the ear, may be partly responsible for the link between HL, tinnitus, neck pain, and migraine.

Trends and patterns of neurotology drug prescriptions on a nationwide insurance database

OBJECTIVE

To examine neurotologists' 2013 to 2016 Medicare Part-D data and evaluate commonly prescribed medications, longitudinal changes in prescribing patterns, presumed associated pathologies, and cost distribution across United States.

METHODS

Comprehensive prescription data of Part-D-participating neurotologists was quiered from the 2013 to 2016 Medicare Part-D database. Outcome variables consisted of the 25 most commonly prescribed + refilled medications, cost distribution per medication, presumed associated pathologies, and standardized prescription cost across United States.

RESULTS

Of the 594 available U.S. neurotologists, 336 (57%) were found in the Medicare Part-D database. In 2016, total prescription costs were $4 483 268 with an averaged $13 343 ± $18 698 per neurotologist. The three most frequently filled drugs were fluticasone propionate, ciprofloxacin, and triamterene-hydrochlorothiazide. From 2013 to 2016, the greatest change in prescription pattern was observed with azelastine (+188%), montelukast sodium (+104%), mupirocin (+63%), and mometasone (-91%), whereas the greatest change in relative drug cost distribution was seen in ofloxacin, (+695.7%) neomycin-polymyxin-hydrocortisone (+262.1%), and mometasone (-83%). Triamterene-hydrochlorothiazide, prednisone, montelukast, amoxicillin-clavulanate, azelastine, spironolactone, and mupirocin had statistically significant increases in average number of prescriptions per physician, whereas ofloxacin and mometasone had significant decreases. Medications presumably treating Eustachian tube dysfunction, Meniere's disease, and vestibular migraine had the greatest percent changes across years. Cost distribution of four drugs increased upwards of 100%. Geographic analysis demonstrated that Southern and Midwest regions had higher standardized prescription costs.

CONCLUSIONS

This study is the first to analyze neurotologists' trends in prescribing patterns, regional prescription cost distributions, and commonly treated pathologies. This can lead to better standardization of prescribing patterns and cost in the future.

Treatment of Long-term Sudden Sensorineural Hearing Loss as an Otologic Migraine Phenomenon

OBJECTIVES

To describe a cohort of patients presenting with long-term sudden sensorineural hearing loss (SSNHL) treated with prophylactic migraine and intratympanic steroid therapy.

METHODS

Patients presenting to a neurotology clinic at least 6 weeks from SSNHL onset were included. All patients received migraine prophylactic medication (nortriptyline, topiramate, and/or verapamil) and lifestyle changes for at least 6 weeks, as well as intratympanic steroid injections, if appropriate.

RESULTS

Twenty-one patients (43% female) with a mean age of 64 ± 11 years who presented 9 ± 8 months (median = 5) from symptom onset were included. Posttreatment hearing thresholds were significantly improved compared with pretreatment thresholds at 500 Hz (49 ± 19 dB versus 55 ± 20 dB, p = 0.01), 1000 Hz (52 ± 19 dB versus 57 ± 21 dB, p = 0.03), low-frequency pure-tone average (53 ± 15 dB versus 57 ± 17 dB, p = 0.01), and speech-frequency pure-tone average (57 ± 13 dB versus 60 ± 15 dB, p = 0.02). Posttreatment word-recognition-score (WRS) and speech-recognition-threshold (SRT) were also significantly improved (45 ± 28% versus 70 ± 28% and 57 ± 18 dB versus 50 ± 16 dB, respectively, both p < 0.01). Notably, ≥15% improvement in WRS and ≥10 dB improvement in SRT was observed in 13 (68%) and 8 (40%) patients, respectively. Of the 11 patients who presented with initial < 50% WRS, 8 (73%) had improved posttreatment >50% WRS with an average improvement of 39 ± 9%.

CONCLUSIONS

Migraine medications in addition to intratympanic steroid injections significantly improved SRT and hearing frequencies in 40% and 29% of SSNHL patients, respectively, while significant WRS recovery was observed in most (68%) patients. This suggests SSNHL may be an otologic migraine phenomenon, which may be at least partially reversible even after the traditional 30-day postonset window.

Association between modified frailty index and surgical outcomes in intradural skull base surgery

The objective of this study is to evaluate the impact of preoperative frailty on short-term outcomes following intradural resection of skull base lesions. The 2005-2017 ACS-NSQIP database was queried for 30-day post-operative outcomes of patients undergoing intradural resection of the skull base, extracted by CPT codes 61601, 61606, 61608, and 61616. Five-item modified frailty index (mFI) was calculated based on the history of diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, chronic hypertension, and functional status. A total of 701 patients (58.8% female, 72.0% white) were included with a mean age of 51.8 ± 14.7 years. Compared to patients with mFI = 0 (n = 403), patients with mFI ≥ 1 (n = 298) were more likely to have higher rates of reoperation (13.4% vs. 8.7%, p = 0.045), medical complications (20.5% vs. 9.2%, p < 0.001), surgical complications (13.8% vs. 8.4%, p = 0.024), discharge to non-home facility (DNHF) (24.8% vs. 13.3%, p < 0.001), and prolonged length of hospitalization (7.3 ± 6.8 days vs. 5.6 ± 5.0, p = 0.003). Moreover, mFI = 1-3 was also associated with higher BMI, non-white race, high ASA, and older age (all p < 0.05). Upon adjusting for age, BMI, race, ASA score, and surgical site, multivariate regression analysis demonstrated that higher mFI (treated as a continuous variable) was associated with higher odds of medical complications (OR = 1.630, CI = 1.153-2.308, p = 0.006), surgical complications (OR = 1.594, CI = 1.042-2.438, p < 0.031), and LOS ≥ 10 days (OR = 1.609, CI = 1.176-2.208, p = 0.003). In conclusion, the 5-item mFI can be an independent predictor of several important short-term surgical outcomes following intradural resection of skull base lesions, warranting further investigations into its clinical utility.

The Relationship Between Vestibular Migraine and Motion Sickness Susceptibility

OBJECTIVES

To determine the relationship between vestibular migraine (VM) and motion sickness (MoS) susceptibility and their comorbidity in a large student population, and to assess whether experiencing MoS is associated with higher susceptibility for VM.

METHODS

Surveys including Motion Sickness Susceptibility Questionnaire (MSSQ) and questions assessing migraine-related symptoms as well as family history of motion sickness and migraine headache were distributed to the university undergraduate students through Facebook and email. Diagnosis of definite VM (dVM) was based on the criteria of the International Classification of Headache Disorders.

RESULTS

Of 277 survey responders, 148 (53%) were found to be susceptible to MoS in which 74 (50%) met the criteria for dVM. Only childhood MSSQ score was significantly higher in participants with dVM compared with those without dVM (25.78 ± 15.89 versus 20.77 ± 14.28, p = 0.04); however, its significance faded out by regression analysis. Multivariate logistic regression showed having 1st degree relative with migraine headache (p = 0.02), neck stiffness (p = 0.001), and sinus pain, facial pressure, or headache with wind exposure (p = 0.02) to be independently associated with presence of dVM in MoS subjects.

CONCLUSIONS

Though participants with MoS and dVM had significantly greater rates of migraine-related symptoms and family history of migraine headache compared with those with MoS only, childhood and adulthood MSSQ scores were similar. This and the high prevalence of dVM in our MoS cohort may suggest an existing association between MoS susceptibility and VM.

Migraine Features in Patients with Persistent Postural-Perceptual Dizziness

OBJECTIVES

To evaluate the presence of migraine features in patients with persistent postural-perceptual dizziness (PPPD).

METHODS

In a retrospective survey study, consecutive patients presenting to a tertiary care neurotology clinic during an 18-month period were given questionnaires about headache and dizziness symptoms. The survey responses plus history and examination of the patient were used to diagnose patients with PPPD. The prevalence of migraine headache, vestibular migraine (VM), and migraine characteristics was evaluated.

RESULTS

In total, 36 subjects with PPPD were included in the study. The mean age of the subjects was 56 ± 16 years with a female (72%) predominance. A total of 19 (53%) patients met the International Classification of Headache Disorders criteria for migraine headache, and 6 of those (17%) met the criteria for definite VM. Of the patients who did not meet full migraine headache criteria, 6 (17%) patients met 4 of 5 criteria, and 5 (14%) patients met 3 of 5 criteria. There was no significant difference between PPPD patients who fulfilled full migraine headache criteria and those who did not in sensitivity to light, sound, smells, weather changes, feelings of mental fog/confusion, and sinus pain/facial pressure.

CONCLUSIONS

This study demonstrates that a majority of patients with PPPD fulfill the criteria for migraine headache. A large proportion of PPPD patients who do not meet the full criteria for migraine headache still meet a majority of the migraine headache criteria. This suggests an association between the 2 conditions. PPPD may be a part of the spectrum of otologic migraine, where migraine manifests as otologic symptoms.

Treatment Analysis and Overall Survival Outcomes of Patients With Bilateral Vestibular Schwannoma

OBJECTIVES

To investigate the clinical presentation, treatment breakdown, and overall survival (OS) outcomes of patients with neurofibromatosis type 2 (NF2)-associated bilateral vestibular schwannoma (NVS).

METHODS

The 2004 to 2016 National Cancer Database was queried for patients with a diagnosis of VS. The "Laterality" code was used to stratify patients into sporadic unilateral vestibular schwannoma (UVS) and NVS.

RESULTS

Of the 33,839 patients with VS, 155 (0.46%) were coded for NVS with an average age and tumor size of 37.4 ± 20.5 years and 23.5 ± 18.2 mm. Patients underwent observation (45.3%), surgery (29.3%), and radiotherapy (20.0%), and had a 5.8% 5-year mortality rate. Compared with UVS, NVS was negatively associated with receiving surgery (40.2% versus 29.3%, p = 0.02) while watchful observation was more prevalent (30.1% versus 45.3%, p = 0.001). In NVS, undergoing surgery was associated with larger tumor size (34.5 ± 21.2 versus 17.8 ± 13.3 mm, p = 0.001) and shorter diagnosis-to-treatment time (49.1 ± 60.6 versus 87.0 ± 78.5 d, p = 0.02), radiotherapy was associated with older age (44.4 ± 18.9 versus 35.2 ± 20.6 yr, p = 0.02) and longer diagnosis-to-treatment time (85.9 ± 77.9 versus 53.9 ± 65.5 d, p = 0.04), and observation was associated with smaller tumor size (17.8 ± 15.9 versus 28.0 ± 19.2 mm, p = 0.01). Kaplan-Meier log-rank analysis demonstrated similar 10-year OS between NVS and UVS patients (p = 0.58) without factoring the earlier age of presentation. Furthermore, there were no temporal changes in presentation/management of NVS, and OS was not dependent on the received treatment (p = 0.30).

CONCLUSIONS

With younger age, larger tumors, and more conservative management, NVS's OS was not treatment-dependent and was similar to sporadic UVS, though the latter should not be interpreted as similar life expectancies due to the much earlier presentation.

Migraine Features in Patients With Recurrent Benign Paroxysmal Positional Vertigo

OBJECTIVES

To identify migraine features present in a cohort of patients with recurrent benign paroxysmal positional vertigo (BPPV).

METHODS

Patients presenting with recurrent BPPV were surveyed. Recurrent BPPV was defined as three episodes or greater in 6 months before presentation, with resolution of symptoms after Epley maneuver. Current or past migraine headache (MH) diagnosis was made according to the International Headache Society guidelines.

RESULTS

Fifty-eight patients with recurrent BPPV with a mean age of 53.8 ± 17.4 years were included. Half (29 patients) fulfilled criteria for MH and half (29 patients) did not meet the criteria for MH (non-MH). No statistically significant difference was found in a majority of migraine-related symptoms between the MH and non-MH cohorts with recurrent BPPV. History of migraine medication usage (p = 0.008), presence of a weekly headache (p = 0.01), and duration of dizziness after positional vertigo (p = 0.01) were the only variables that were different on multivariate analysis between the MH and non-MH cohorts.

CONCLUSIONS

Half of recurrent BPPV patients suffer from migraine headaches. The other half presented with migraine-related symptoms, but do not meet criteria for MH. The high comorbidity of MH in our recurrent BPPV cohort as well as the absence of a statistically significant difference in a majority of migraine-related features among patients who did and did not fulfill criteria for MH may suggest that recurrent BPPV has a relationship with migraine. Recurrent BPPV may potentially be a manifestation of migraine in the inner ear, which we term otologic migraine including cochlear, vestibular, or cochleovestibular symptoms.

Online Ratings and Perceptions of Pediatric Otolaryngologists

OBJECTIVE/HYPOTHESIS

To assess and characterize online ratings and comments on pediatric otolaryngologists and determine factors that correlate with higher ratings.

STUDY DESIGN

Online database analysis.

METHODS

All American Society of Pediatric Otolaryngology (ASPO) members were queried on Healthgrades, Vitals, RateMDs, and Yelp for their online ratings and comments as of June 2020. Ratings were normalized for comparison on a five-point Likert scale. All comments were categorized based on context and positive or negative quality.

RESULTS

Of the 561 ASPO members, 489 (87%) were rated on at least one online platform. Of those rated, 410 (84%) were on Healthgrades, 429 (88%) on Vitals, 236 (48%) on RateMDs, and 72 (15%) on Yelp. Across all platforms, the average overall rating was 4.13 ± 0.03 (range, 1.00-5.00). We found significant positive correlations between overall ratings and specific ratings (P < .001) on all individual topics. In addition, the majority of all narrative comments were related to perceived physician bedside manner and clinical outcome, with negative comments correlating negatively with overall score (P < .05). Time spent with the physician was the only category in which both positive and negative comments showed significant correlation with the overall physician rating (P = .016 and P = .017, respectively). Attending a top-ranked medical school or residency program did not correlate with higher or lower ratings.

CONCLUSIONS

Online ratings and comments for pediatric otolaryngologists are largely influenced by patient and parent perceptions of physician competence, comforting bedside manner, and office and time management.

Machine learning models to predict length of stay and discharge destination in complex head and neck surgery

BACKGROUND

This study develops machine learning (ML) algorithms that use preoperative-only features to predict discharge-to-nonhome-facility (DNHF) and length-of-stay (LOS) following complex head and neck surgeries.

METHODS

Patients undergoing laryngectomy or composite tissue excision followed by free tissue transfer were extracted from the 2005 to 2017 NSQIP database.

RESULTS

Among the 2786 included patients, DNHF and mean LOS were 421 (15.1%) and 11.7 ± 8.8 days. Four classification models for predicting DNHF with high specificities (range, 0.80-0.84) were developed. The generalized linear and gradient boosting machine models performed best with receiver operating characteristic (ROC), accuracy, and negative predictive value (NPV) of 0.72-0.73, 0.75-0.76, and 0.88-0.89. Four regression models for predicting LOS in days were developed, where all performed similarly with mean absolute error and root mean-squared errors of 3.95-3.98 and 5.14-5.16. Both models were developed into an encrypted web-based interface: https://uci-ent.shinyapps.io/head-neck/.

CONCLUSION

Novel and proof-of-concept ML models to predict DNHF and LOS were developed and published as web-based interfaces.

Short-Term Morbidity and Predictors of Adverse Events Following Esthesioneuroblastoma Surgery

INTRODUCTION

The short-term adverse events and predictors of morbidity in surgical resection of esthesioneuroblastoma (ENB) are largely unknown, and investigating these variables can help direct planning for at-risk patients.

METHODS

The 2005-2017 National Surgical Quality Improvement Program database was queried to identify patients with a diagnosis of ENB undergoing skull base surgery for tumor resection. Information regarding demographics, patient morbidity score, pre-operative and intra-operative data, and post-operative outcomes were extracted. Cox proportional hazard analysis was utilized to assess complication and readmission/reoperation rates.

RESULTS

A total of 95 patients undergoing skull base surgery for resection of ENB were included. Mean age, BMI, operation time, and post-operative length of stay (LOS) of the cohort were 53.6 ± 16.2 years, 29.1 ± 6.5, 392.0 ± 204.6 minutes, and 5.8 ± 4.6 days, respectively. In total, 31 patients (32.6%) experienced at least one 30-day adverse event, which included blood transfusion intra-operatively or within 72 hours from the operation (22.1%), readmission (10.7%), intubation >48 hours (7.4%), reintubation (4.2%), organ or space infection (4.2%), reoperation (4.0%), superficial or deep surgical site infection (2.1%), sepsis (2.1%), pulmonary embolism (1.1%), and myocardial infarction (1.1%). Patients who experienced at least one adverse event had significantly higher operation time (486.8 ± 230.4 vs. 347.5 ± 176.2 minutes, p = 0.002), LOS (9.2 ± 5.6 days vs. 4.2 ± 3.0, p < 0.001), and lower hematocrit (37.3 ± 5.9 vs. 41.2 ± 3.8, p < 0.001) and albumin levels (3.8 ± 0.6 vs. 4.2 ± 0.3, p = 0.009). Patients with a higher American Society of Anesthesiologists (ASA) score (HR = 2.39; p = 0.047) or longer operation time (HR = 1.004; p = 0.001) had a significantly higher risk for experiencing adverse events. Obesity was not associated with different intra- or post-operative outcomes, but older patients had shorter operations (p = 0.002) and LOS (p = 0.0014).

CONCLUSION

Longer operation time and lower pre-operative hematocrit and albumin levels may all increase complication rates in ENB resection. Patients with high ASA score or more advanced age may have different short-term outcomes.

Adapting Personal Therapies Using a Mobile Application for Tinnitus Rehabilitation: A Preliminary Study

OBJECTIVES

To develop a smartphone application providing sound therapy and cognitive behavioral therapy (CBT) for treating tinnitus and performing a proof-of-concept pilot study evaluating its potential efficacy.

METHODS

An interactive smartphone application available on iOS and Android platforms was developed, which provided an 8-week tinnitus-specific CBT and personalized and frequency-matched sound therapy. Included patients presented to our tertiary clinic between 2017 and 2018, while those waitlisted were regarded as controls. Three surveys were administrated: Tinnitus Handicap Inventory (THI), Generalized Anxiety Disorder 7-item (GAD-7), and Perceived Stress Scale (PSS).

RESULTS

A total of 30 patients enrolled in this study consisting of 20 treatment and 10 control patients and mean age was 55.4 ± 11.6 years. Treatment and control patients had similar age, sex, and pre-enrolment GAD and PSS (all P > .05). Baseline THI scores were also similar between treatment and control cohorts (50.1 ± 21.9 vs 62.0 ± 20.7; P = .15). After 8 weeks, though changes in GAD and PSS scores were similar (P > .05), the treatment group reported a significantly greater improvement in THI scores (17.7 ± 15.8 vs 5.3 ± 10.5, P = .04).

CONCLUSIONS

This pilot study demonstrated potentially promising efficacy of a smartphone-based CBT and sound therapy platform for treating tinnitus and encourages future randomized controlled trials on this treatment modality.

Perilymphatic Fistula: A Review of Classification, Etiology, Diagnosis, and Treatment

A perilymphatic fistula (PLF) is an abnormal communication between the perilymph-filled inner ear and the middle ear cavity, mastoid, or intracranial cavity. A PLF most commonly forms when the integrity of the oval or round window is compromised, and it may be trauma-induced or may occur with no known cause (idiopathic). Controversy regarding the diagnosis of idiopathic PLF has persisted for decades, and the presenting symptoms may be vague. However, potential exists for this condition to be one of the few etiologies of dizziness, tinnitus, and hearing loss that can be treated surgically. The aim of this review is to provide an update on classification, diagnosis, and treatment of PLF. Particular attention will be paid to idiopathic PLF and conditions that may have a similar presentation, with subsequent information on how best to distinguish them. Novel diagnostic criteria for PLF and management strategy for PLF and PLF-like symptoms is presented.

Academic Rhinologists' Online Rating and Perception, Scholarly Productivity, and Industry Payments

INTRODUCTION

The emergence of popular online rating websites, social media platforms, and public databases for industry payments and scholarly outputs provide a complete physician online presence which may guide choice and satisfaction.

METHODS

Websites of all U.S. otolaryngology academic institutions were queried for fellowship-trained rhinologists. Additional well-known and academically active rhinologists were identified by the senior author. Online ratings and comments were collected from Google, Healthgrades, Vitals, and RateMD websites, and weighted rating scores (RS) were calculated on a 1-5 scale.

RESULTS

A total of 210 rhinologists with 16 ± 9 years of practice were included, where 6901 online ratings (33 ± 47 per rhinologist) provided an average RS of 4.3 ± 0.6. RS was not different according to gender (p = 0.58), geographic quartile (p = 0.48), social media presence (p = 0.41), or attending top-ranked medical school (p = 0.86) or residency programs (p = 0.89). Years of practice negatively correlated with RS (R = -0.22, p<0.01), and academic ranking significantly influenced RS, with professors, associate professors, and assistant professors scoring 4.1 ± 0.6, 4.3 ± 0.4, and 4.4 ± 0.6, respectively (p = 0.03). Of the 3,304 narrative comments analyzed (3.1 ± 11.6 per rhinologist), 76% (positive) and 7% (negative) had elements of clinical knowledge/outcomes, 56% (positive) and 7% (negative) of communication/bedside manner, and 9% (positive) and 7% (negative) of office staff, cost, and wait-time. All negative comment categories had moderate negative correlation with RS, while positive comment categories regarding knowledge/competence and bedside manner weakly correlated with higher RS. Number of publications (48 ± 54) positively correlated with 2018 industry payments ($11,384 ± $19,025) among those receiving industry compensation >$300 (n = 113). Attending a top-ranked medical school was associated with higher industry payments (p<0.01) and H-index (p = 0.02).

CONCLUSION

Academic rhinologists' online RS was not associated with gender, geographic location, or attending a top-ranked training program, and their scholarly productivity was significantly correlated with total industry payments.

The Effects of Pass/Fail USMLE Step 1 Scoring on the Otolaryngology Residency Application Process

OBJECTIVES

To investigate how the decision to report United States Medical Licensing Examination (USMLE) Step 1 score as pass/fail will influence future otolaryngology residency application and match processes.

STUDY DESIGN

Survey study.

METHODS

An anonymous and voluntary survey approved by the Otolaryngology Program Directors Organization was administered to academic faculty members from April 24, 2020 through May 19, 2020.

RESULTS

Two hundred fifty-seven surveys were received from department chairs (17.5%), program directors (24.1%), associate program directors (12.5%), and department faculty (45.9%). USMLE Step 1 has been the most heavily weighted metric for offering interviews (44.0%), and it has correlated with residents' medical knowledge (77.0%) and in-service performance (79.8%) but not with surgical skills (57.6%) or patient care (47.1%). In total, 68.1% disagreed with the decision to make USMLE Step 1 pass/fail. This change is anticipated to lead to an increase in significance of USMLE Step 2 CK (89.1%), core clerkship grades (80.9%), elective rotation at the respective institutions (65.7%), Alpha Omega Alpha and other awards (64.6%), and letters of recommendation (63.8%). The new scoring is also anticipated to especially benefit students from top-ranked schools (70.8%), increase medical students' anxiety/uncertainty regarding obtaining interview invites (59.1%), and negatively affect international (51.4%), doctor of osteopathic medicine (45.9%), and underrepresented students (36.9%). Indication that USMLE Step 2 CK will significantly increase in weight varied according to department position (P = .049), geographic region (P = .047), years of practice (P < .001), and residency program size (P = .002).

CONCLUSION

Most academic otolaryngologists disagreed with changing USMLE Step 1 scoring to pass/fail and believe that it will increase other objective/subjective metrics' weight and put certain student populations at a disadvantage.

Adjuvant Migraine Medications in the Treatment of Sudden Sensorineural Hearing Loss

OBJECTIVES/HYPOTHESIS

To examine the hearing outcomes of patients with sudden sensorineural hearing loss (SSNHL) treated with oral and intratympanic (IT) steroid only or a combination of steroid and migraine treatment. Our hypothesis was that adjuvant migraine medications may improve outcomes in SSNHL.

METHODS

A retrospective chart review at a tertiary otology center was conducted to identify patients with SSNHL who received oral steroid and IT dexamethasone injection(s) with or without migraine medications (a combination of nortriptyline and topiramate).

RESULTS

A total of 47 patients received oral steroid and IT dexamethasone injection(s) only, and 46 patients received oral steroid and IT dexamethasone injection(s) as well as migraine lifestyle changes plus a combination of nortriptyline and topiramate. There were no significant differences in demographics and baseline audiometric data between the two groups. Both groups demonstrated improvements in pure tone average (PTA) and hearing thresholds at 250 Hz and 8000 Hz posttreatment. However, compared to steroid-only group, the adjuvant migraine medications group had significantly greater improvements in hearing thresholds at the lower frequencies (250 Hz, 500 Hz, 1000 Hz). Patients in the latter cohort also had greater improvement in PTA (P = .01) and received fewer IT injections (P = .04) PTA improvement of ≥ 10 dB was observed in 36 patients (78%) in the adjuvant migraine medications group and 22 patients (46%) in the control group (P < .001).

CONCLUSION

In multimodal treatment of SSNHL, supplementing oral and IT steroid with migraine medications may result in greater improvements in lower frequency hearing thresholds and PTA. Furthermore, adjuvant migraine treatment can lead to decrease in number of IT injections, thus reducing procedure-related risks and complications.

Prediction of vestibular schwannoma recurrence using artificial neural network

OBJECTIVES

To compare two statistical models, namely logistic regression and artificial neural network (ANN), in prediction of vestibular schwannoma (VS) recurrence.

METHODS

Seven hundred eighty-nine patients with VS diagnosis completed an online survey. Potential predictors for recurrence were derived from univariate analysis by reaching the cut off P value of .05. Those nine potential predictors were years since treatment, surgeon's specialty, resection amount, and having incomplete eye closure, dry eye, double vision, facial pain, seizure, and voice/swallowing problem as a complication following treatment. Multivariate binary logistic regression model was compared with a four-layer 9-5-10-1 feedforward backpropagation ANN for prediction of recurrence.

RESULTS

The overall recurrence rate was 14.5%. Significant predictors of recurrence in the regression model were years since treatment and resection amount (both P < .001). The regression model did not show an acceptable performance (area under the curve [AUC] = 0.64; P = .27). The regression model's sensitivity and specificity were 44% and 69%, respectively and correctly classified 56% of cases. The ANN showed a superior performance compared to the regression model (AUC = 0.79; P = .001) with higher sensitivity (61%) and specificity (81%), and correctly classified 70% of cases.

CONCLUSION

The constructed ANN model was superior to logistic regression in predicting patient-answered VS recurrence in an anonymous survey with higher sensitivity and specificity. Since artificial intelligence tools such as neural networks can have higher predictive abilities compared to logistic regression models, continuous investigation into their utility as complementary clinical tools in predicting certain surgical outcomes is warranted.

Endoscopic versus nonendoscopic surgery for resection of pituitary adenomas: a national database study

OBJECTIVE

For symptomatic nonsecreting pituitary adenomas (PAs), resection remains a critical option for treatment. In this study, the authors used a large-population national database to compare endoscopic surgery (ES) to nonendoscopic surgery (NES) for the surgical management of PA.

METHODS

The National Cancer Database was queried for all patients diagnosed with histologically confirmed PA who underwent resection between 2010 and 2016 in which the surgical approach was specified. Due to database limitations, microsurgery and craniotomy were both categorized as NES.

RESULTS

Of 30,488 identified patients, 16,373 (53.7%) underwent ES and 14,115 (46.3%) underwent NES. There was a significant increase in the use of ES over time (OR 1.16, p < 0.01). Furthermore, there was a significant temporal increase in ES approach for tumors ≥ 2 cm (OR 1.17, p < 0.01). Compared to NES, patients who underwent ES were younger (p = 0.01), were treated at academic centers (p < 0.01), lived a greater distance from their treatment site (p < 0.01), had smaller tumors (p < 0.01), had greater medical comorbidity burden (p = 0.04), had private insurance (p < 0.01), and had a higher household income (p < 0.01). After propensity score matching to control for age, tumor size, Charlson/Deyo score, and type of treatment center, patients who underwent ES had a shorter length of hospital stay (LOS) (3.9 ± 4.9 days vs 4.3 ± 5.4 days, p < 0.01), although rates of gross-total resection (GTR; p = 0.34), adjuvant radiotherapy (p = 0.41), and 90-day mortality (p = 0.45) were similar. On multivariate logistic regression, African American race (OR 0.85, p < 0.01) and tumor size ≥ 2 cm (OR 0.89, p = 0.01) were negative predictors of receiving ES, whereas diagnosis in more recent years (OR 1.16, p < 0.01), greater Charlson/Deyo score (OR 1.10, p = 0.01), receiving treatment at an academic institution (OR 1.67, p < 0.01) or at a treatment site ≥ 20 miles away (OR 1.17, p < 0.01), having private insurance (OR 1.09, p = 0.01), and having a higher household income (OR 1.11, p = 0.01) were predictive of receiving ES. Compared to the ES cohort, patients who started with ES and converted to NES (n = 293) had a higher ratio of nonwhite race (p < 0.01), uninsured insurance status (p < 0.01), longer LOS (p < 0.01), and higher rates of GTR (p = 0.04).

CONCLUSIONS

There is an increasing trend toward ES for PA resection including its use for larger tumors. Although ES may result in shorter LOS compared to NES, rates of GTR, need for adjuvant therapy, and short-term mortality may be similar. Factors such as tumor size, insurance status, facility type, income, race, and existing comorbidities may predict receiving ES.

Efficacy of Multi-Modal Migraine Prophylaxis Therapy on Hyperacusis Patients

OBJECTIVES

To evaluate the efficacy of a multi-modal migraine prophylaxis therapy for patients with hyperacusis.

METHODS

In a prospective cohort, patients with hyperacusis were treated with a multi-modal step-wise migraine prophylactic regimen (nortriptyline, verapamil, topiramate, or a combination thereof) as well as lifestyle and dietary modifications. Pre- and post-treatment average loudness discomfort level (LDL), hyperacusis discomfort level measured by a visual analogue scale (VAS), and scores on the modified Khalfa questionnaire for severity of hyperacusis were compared.

RESULTS

Twenty-two of the 25 patients (88%) reported subjective resolution of their symptoms following treatment. Post-treatment audiograms showed significant improvement in average LDL from 81.3 ± 3.2 dB to 86.4 ± 2.6 dB (P < .001), indicating increased sound tolerability. The VAS discomfort level also showed significant improvement from a pre-treatment average of 7.7 ± 1.1 to 3.7 ± 1.6 post-treatment (P < .001). There was also significant improvement in the average total score on modified Khalfa questionnaire (32.2 ± 3.6 vs 22.0 ± 5.7, P < .001).

CONCLUSIONS

The majority of patients with hyperacusis demonstrated symptomatic improvement from migraine prophylaxis therapy, as indicated by self-reported and audiometric measures. Our findings indicate that, for some patients, hyperacusis may share a pathophysiologic basis with migraine disorder and may be successfully managed with multimodal migraine prophylaxis therapy.

Proposal for a new diagnosis for U.S. diplomats in Havana, Cuba, experiencing vestibular and neurological symptoms

Between 2016 and 2017, several U.S. Diplomats in Havana, Cuba, experienced perplexing vestibular and neurological symptoms attributed to an unknown source. They presented with significant vestibular and headache symptoms similar to individuals who experience vestibular migraine (VM). As such, we hypothesize that VM may be a possible explanation for the Havana cohort's presenting symptoms. To evaluate this hypothesis, we compared symptoms reported by the affected individuals in Havana, Cuba, to symptoms reported by corresponding patients from a tertiary academic neurotology clinic with a chief complaint of vertigo or disequilibrium, who met the International Classification of Headache Disorders criteria for VM. The prevalence of the Havana subjects experiencing various symptomatic domains was compared with the VM cohort, leading to 26 unique domains and statistical comparisons between the cohorts. Of the 26 domains compared between the two cohorts, 18 were not significantly different. This included the two most important components of meeting criteria for VM, namely the co-existence of headache and vestibular symptoms. On regression analysis, the only feature which kept its significant difference between the two cohorts was acute intense head pressure (P = 0.007). The domains with similar occurrence ratios included dizziness, headache, light sensitivity, hearing reduction, and tinnitus. In other words, multiple headache and vestibular symptoms, consistent with VM criteria, were similar between the two cohorts. The considerable similarities across various domains between VM patients and Havana subjects could be due to migraine as a possible common etiology for both groups. We propose VM as a potential etiology for the symptomatology in the U.S. diplomats in Cuba.

A hypothetical proposal for association between migraine and Meniere's disease

Meniere's disease (MD) is a chronic condition affecting the inner ear whose precise etiology is currently unknown. We propose the hypothesis that MD is a migraine-related phenomenon which may have implications for future treatment options for both diseases. The association between MD and migraine is both an epidemiological and a mechanistic one, with up to 51% of individuals with MD experiencing migraine compared to 12% in the general population. The presence of endolymphatic hydrops in those with MD may be the factor that unites the two conditions, as hydropic inner ears have an impaired ability to maintain homeostasis. Migraine headaches are theorized to cause aura and symptoms via spreading cortical depression that ultimately results in substance P release, alterations in blood flow, and neurogenic inflammation. Chronically hydropic inner ears are less able to auto-regulate against the changes induced by active migraine attacks and may ultimately manifest as MD. This same vulnerability to derangements in homeostasis may also explain the common triggering factors of both MD attacks and migraine headaches, including stress, weather, and diet. Similarly, it may explain the efficacy of common treatments for both diseases: current migraine treatments such as anti-hypertensives and anti-convulsants have shown promise in managing MD. Though the etiology of both MD and migraine is likely multifactorial, further exploration of the association between the two conditions may illuminate how to best manage them in the future. MD is likely a manifestation of cochleovestibular migraine, which occurs as a result of migraine related changes in both the cochlea and vestibule.

Efficacy of steroid-eluting stents in management of chronic rhinosinusitis after endoscopic sinus surgery: updated meta-analysis

BACKGROUND

Recently, there has been mounting evidence suggesting the efficacy of steroid-eluting stents (SES) for management of chronic rhinosinusitis after endoscopic sinus surgery (ESS). This meta-analysis serves to evaluate the efficacy of SES in improving postoperative outcomes after ESS.

METHODS

A systematic literature search was performed of PubMed for articles published between 1985 and 2018. The outcome variables were reported at, on average, 30 days postintervention.

RESULTS

Seven of the 76 published studies, all of which were industry-sponsored, were included for a collective cohort of 444 SES and 444 control sinuses. In patients who received SES vs controls, collective odds ratios (ORs) for postoperative need for intervention, surgery, and oral steroid were 0.45 (95% confidence interval [CI], 0.33-0.62; p < 0.001), 0.30 (95% CI, 0.18-0.52; p < 0.001), and 0.58 (95% CI, 0.40-0.84; p = 0.004), respectively. In addition, collective ORs for frontal sinus ostia (FSO) patency, moderate-to-severe adhesion/scarring, and increase in polyp score were 2.53 (95% CI, 1.61-3.97; p < 0.001), 0.28 (95% CI, 0.13-0.59; p < 0.001), and 0.42 (95% CI, 0.25-0.74; p = 0.002), respectively. Collective mean differences for FSO/ethmoid inflammation and FSO diameter were -10.86 mm (p < 0.001) and +1.34 mm (p < 0.001), respectively.

CONCLUSION

Aggregate evidence suggests that SES can improve ESS outcomes by reducing rates of postoperative intervention and recurrent polyposis and inflammation, while promoting FSO patency. All included and analyzed studies were industry-sponsored and ruling-out publication bias was not possible. Future independent and nonsponsored studies to further evaluate SES's long-term efficacy are warranted.

Hyams grading as a predictor of metastasis and overall survival in esthesioneuroblastoma: a meta-analysis

BACKGROUND

Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, represents up to 3% of all sinonasal neoplasms. Hyams histologic grading is a promising tool in predicting metastases and establishing prognoses for this complex tumor.

METHODS

A systematic literature search was performed in the PubMed, Ovid MEDLINE, and Cochrane databases. ENB patients with Hyams I-II or III-IV were categorized as low-grade Hyams (LGH) or high-grade Hyams (HGH), respectively. Binary and continuous random-effects models were applied to calculate odds ratios (ORs) for the incidences of neck and distal metastases as well as for 5- and 10-year overall survival rates.

RESULTS

Of the 57 screened articles published from 1993 to 2018, 16 (525 patients) and 21 (563 patients) provided data for tumor metastases and overall survival rates, respectively. Neck metastasis was observed in 18.2% of HGH vs 7.9% of LGH patients. Distant metastasis was noted in 20.7% of HGH vs 8.9% of LGH patients. LGH patients had 5- and 10-year overall survival rates of 81.2% and 64.0%, respectively, as compared with 60.9% and 40.6%, respectively, for HGH patients. In comparing HGHs vs LGHs, the collective ORs for neck and distant metastases were 2.08 (95% confidence interval [CI], 1.09-3.99; p = 0.03) and 2.37 (95% CI, 1.07-5.26; p = 0.03), respectively. Moreover, in comparing LGHs vs HGHs, collective ORs for 5- and 10-year overall survival rates were 3.39 (95% CI, 2.09-5.49; p < 0.001) and 3.03 (95% CI, 1.82-5.06; p < 0.001), respectively.

CONCLUSION

HGH ENBs, compared with LGH ENBs, are more likely to metastasize to neck or distal targets and to have lower overall survival rates.
