The role of artificial intelligence in training ENT residents: a survey on ChatGPT, a new method of investigation

Objective

The primary focus of this study was to analyze the adoption of ChatGPT among Ear, Nose, and Throat (ENT) trainees, encompassing its role in scientific research and personal study. We examined in which year ENT trainees become involved in clinical research and how many scientific investigations they have been engaged in.

Methods

An online survey was distributed to ENT residents employed in Italian University Hospitals.

Results

Out of 609 Italian ENT trainees, 181 (29.7%) responded to the survey. Among these, 67.4% were familiar with ChatGPT, and 18.9% of them used artificial intelligence as a tool for research and study. In all, 32.6% were not familiar with ChatGPT and its functions. Within our sample, there was an increasing trend of participation by ENT trainees in scientific publications throughout their training.

Conclusions

ChatGPT remains relatively unfamiliar and underutilised in Italy, even though it could be a valuable and efficient tool for ENT trainees, providing quick access for study and research through both personal computers and smartphones.

Subtotal Petrosectomy: Pictorial Review of Clinical Indications and Surgical Approach

Subtotal petrosectomy (STP) is characterized by obliteration of the middle ear and occlusion of the external auditory canal. The advent of the endoscope has allowed a reduction in morbidity for some conditions such as cholesteatoma and other middle ear disorders, but STP still plays an important role. A retrospective review of medical records and videos of patients who had undergone STP was performed. Perioperative data and images were collected from various clinical cases who had undergone subtotal petrosectomy at our tertiary referral university hospital in Verona. We confronted our experience with a review of the literature to present the main indications for this type of procedure. STP allows a variety of diseases to be managed effectively as it offers the possibility of a definitive healing with radical clearance of temporal bone. Moreover, it can be safely combined with other procedures with a very low complication rate. Although the endoscope represents a revolution in ear surgery, STP, when indicated, is nowadays a surgical option that should be included in the otosurgeon's portfolio.

Polyphenols in Inner Ear Neurobiology, Health and Disease: From Bench to Clinics

There is substantial experimental and clinical interest in providing effective ways to both prevent and slow the onset of hearing loss. Auditory hair cells, which occur along the basilar membrane of the cochlea, often lose functionality due to age-related biological alterations, as well as from exposure to high decibel sounds affecting a diminished/damaged auditory sensitivity. Hearing loss is also seen to take place due to neuronal degeneration before or following hair cell destruction/loss. A strategy is necessary to protect hair cells and XIII cranial/auditory nerve cells prior to injury and throughout aging. Within this context, it was proposed that cochlea neural stem cells may be protected from such aging and environmental/noise insults via the ingestion of protective dietary supplements. Of particular importance is that these studies typically display a hormetic-like biphasic dose-response pattern that prevents the occurrence of auditory cell damage induced by various model chemical toxins, such as cisplatin. Likewise, the hormetic dose-response also enhances the occurrence of cochlear neural cell viability, proliferation, and differentiation. These findings are particularly important since they confirmed a strong dose dependency of the significant beneficial effects (which is biphasic), whilst having a low-dose beneficial response, whereas extensive exposures may become ineffective and/or potentially harmful. According to hormesis, phytochemicals including polyphenols exhibit biphasic dose-response effects activating low-dose antioxidant signaling pathways, resulting in the upregulation of vitagenes, a group of genes involved in preserving cellular homeostasis during stressful conditions. Modulation of the vitagene network through polyphenols increases cellular resilience mechanisms, thus impacting neurological disorder pathophysiology. Here, we aimed to explore polyphenols targeting the NF-E2-related factor 2 (Nrf2) pathway to neuroprotective and therapeutic strategies that can potentially reduce oxidative stress and inflammation, thus preventing auditory hair cell and XIII cranial/auditory nerve cell degeneration. Furthermore, we explored techniques to enhance their bioavailability and efficacy.

The Role of Fibrinogen, Homocysteine and Metabolic Syndrome's Alterations in Sudden Sensorineural Hearing Loss (SSHL): A Narrative Review

Fibrinogen and homocysteine (HCY) are molecules known to play a role in vascular homeostasis, and their blood levels are often elevated in patients with metabolic syndrome. Recent evidence suggests that sudden sensorineural hearing loss (SSHL) may have a vascular origin. This has led many authors to advocate that fibrinogen, homocysteine, and metabolic syndrome (MetS) may play a direct role in SSHL. The aim of this brief review is to examine the role and influence of these molecules and MetS on the mechanisms of SSHL. Elevated fibrinogen levels have been associated with a worse prognosis in SSHL, possibly due to increased blood viscosity and decreased blood flow. Similarly, HCY has been associated with vascular damage, particularly in hyperhomocysteinemia, although the exact association with SSHL remains controversial. MetS has been demonstrated to function both as a causative factor and as a contributor to poorer recovery in cases of SSHL. However, although some studies suggest a possible role for these biomarkers and MetS in the prognosis and treatment of SSHL, specific therapeutic and preventive strategies based solely on these factors have yet to be developed. Given their potential role in prognosis and treatment and the global epidemic of metabolic syndrome, this issue needs to be analyzed comprehensively. Thus, further quality studies need to be conducted, even though it is difficult to determine the actual impact of MetS on the development of SSHL, as it is a multifactorial disease affecting multiple organs.

Cochlear Implantation in Children with Additional Disabilities: A Systematic Review

This study examines the last 10 years of medical literature on the benefits of cochlear implantation in children who are deaf or hard of hearing (DHH) with additional disabilities. The most recent literature concerning cochlear implants (CIs) in DHH children with additional disabilities was systematically explored through PubMed, Embase, Scopus, PsycINFO, and Web of Science from January 2012 to July 2023. Our two-stage search strategy selected a total of 61 articles concerning CI implantation in children with several forms of additional disabilities: autism spectrum disorder, cerebral palsy, visual impairment, motor disorders, developmental delay, genetic syndromes, and intellectual disability. Overall, many children with additional disabilities benefit from CIs by acquiring greater environmental sound awareness. This, in turn, improves non-verbal communication and adaptive skills, with greater possibilities to relate to others and to be connected with the environment. Instead, despite some improvement, expressive language tends to develop more slowly and to a lesser extent compared to children affected by hearing loss only. Further studies are needed to better appreciate the specificities of each single disability and to personalize interventions, not restricting the analysis to auditory and language skills, but rather applying or developing cross-culturally validated instruments able to reliably assess the developmental trajectory and the quality of life of DHH children with additional disabilities before and after CI.

Monoclonal Antibodies Targeting CGRP: A Novel Treatment in Vestibular Migraine

Background. Monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP) or its receptor represented the first targeted and specialized approach to migraine prophylaxis. Nevertheless, they have been rarely considered in the treatment of vestibular migraine (VM). Our aim was to evaluate the effectiveness of anti-CGRP mAbs in VM patients who did not respond to conventional migraine treatments. Methods. Consecutive VM patients treated with erenumab were considered. As a comparison, we considered the same VM patients during conventional migraine treatments (i.e., propranolol, flunarizine, or valproic acid), which were tried before mAbs therapy. Videonystagmography, the Italian version of the Dizziness Handicap Inventory (DHI) questionnaire, and migraine days over the last 3 months were evaluated in all patients before and after treatments. Results. In the present retrospective study, we included 21 female and 2 male VM patients, mean age 45.2 years. All patients underwent contrast-enhanced magnetic resonance imaging that ruled out other causes of vertigo. The DHI questionnaire significantly improved after mAb therapy (p < 0.0001). Mean migraine days over the last 3 months were significantly reduced after treatment (p = 0.001). Videonystagmography was altered in 11 (48%) patients prior to monoclonal antibodies. We found vertical positional nystagmus in 9 patients and horizontal positional nystagmus in 2 patients. After the treatment, we found vertical positional nystagmus only in 1 patient (p = 0.002). When patients were treated with conventional therapies, there was no significant reduction in DHI, and instrumental vestibular examinations remained altered. Conclusions. VM patients using anti-CGRP mAbs experienced a reduction in the dizziness-derived handicap, as reported in the DHI questionnaire. Furthermore, these treatments were significantly associated with a normalization of vestibular instrumental analysis. These findings were not seen with conventional treatments. Treatment with anti-CGRP mAbs may be effective in VM patients who did not respond to conventional migraine treatments. These findings should be tested in large, randomized clinical trials.

Updates on Larynx Cancer: Risk Factors and Oncogenesis

Laryngeal cancer is a very common tumor in the upper aero-digestive tract. Understanding its biological mechanisms has garnered significant interest in recent years. The development of laryngeal squamous cell carcinoma (LSCC) follows a multistep process starting from precursor lesions in the epithelium. Various risk factors have been associated with laryngeal tumors, including smoking, alcohol consumption, opium use, as well as infections with HPV and EBV viruses, among others. Cancer development involves multiple steps, and genetic alterations play a crucial role. Tumor suppressor genes can be inactivated, and proto-oncogenes may become activated through mechanisms like deletions, point mutations, promoter methylation, and gene amplification. Epigenetic modifications, driven by miRNAs, have been proven to contribute to LSCC development. Despite advances in molecular medicine, there are still aspects of laryngeal cancer that remain poorly understood, and the underlying biological mechanisms have not been fully elucidated. In this narrative review, we examined the literature to analyze and summarize the main steps of carcinogenesis and the risk factors associated with laryngeal cancer.

Italian validation of the Hearing Handicap Inventory for Elderly - Screening version (HHIE-S-It)

Objective

Validate the Italian version of the Hearing Handicap Inventory for Elderly - Screening version (HHIE-S-It).

Methods

After translation, psychometric properties and attributes were analysed by administering the HHIE-S-It to 167 elderly outpatients together with the Psychological General Well-Being Index (PGWBI).

Results

The Cronbach's α coefficient was 0.908 for the total score, and 0.832 and 0.816 for its two subscales. Significant test-retest reliability was observed (p < 0.001). Moderate to high correlations were found between HHIE-S-It and pure tone average in the better ear (p < 0.001). The ANOVA test confirmed the significant difference in HHIE-S-It scores across groups according to the degree of hearing loss (p < 0.001). Only very low and low significant correlations were observed between HHIE-S-It and PGWBI. The criterion HHIE-S-It > 11 was observed as the best cut-off with highest sensitivity (86.4%), specificity (72.4%), positive predictive value (52.8%), negative predictive value (93.7%) and likelihood ratios (3.12 and 0.19).

Conclusions

Since the HHIE-S-It presented acceptable psychometric properties, its adoption is justified for both clinical and research purposes. Acceptable diagnostic attributes allow its use as a screening tool for age-related hearing loss.

The Effect of Alpha-Lipoic Acid in the Treatment of Chronic Subjective Tinnitus through the Tinnitus Handicap Inventory Scores

BACKGROUND AND OBJECTIVES

Tinnitus affects millions of adults. Many therapies, including complementary and alternative medicine and tinnitus retraining therapies, have been trialed, but an effective option, particularly for chronic subjective tinnitus (CTS), is still lacking.

MATERIALS AND METHODS

This study investigated the effects of alpha-lipoic acid (600 mg. per day for two months) on two groups of patients using a questionnaire. One group (A) was affected by tinnitus associated with likely cochlear dysfunction and metabolic syndrome, and the other (B) was composed of subjects with acoustic nerve lesions. All the patients were asked to complete the Italian version of the tinnitus handicap inventory (THI) to determine the overall degree of perceived annoyance at the beginning and end of therapy. Pure tone averages for speech frequencies and for high frequencies were computed, and psychoacoustic pitch and loudness matches were determined for each subject before and after treatment.

RESULTS

The pure tone audiometry, pitch, loudness, and THI scores of both groups were reported. In group A, statistically significant differences were observed for the "functional" and "emotional" subscales. The total score of THI and the loudness of tinnitus were also significantly reduced. No statistically significant differences were observed in group B.

CONCLUSIONS

These findings suggest a possible contribution of the antioxidant effect to the organ of Corti in subjects with metabolic syndrome and CST.

The Audiological Follow-Up of Children with Symptomatic Congenital Cytomegalovirus Infection: An Experience in Two Italian Centers

BACKGROUND

Congenital cytomegalovirus (cCMV) infection is the leading cause of non-hereditary sensorineural hearing loss in children. While about 10% of children reportedly display symptoms at birth, 85-90% of cCMV infection cases are asymptomatic. However, 10-15% of these asymptomatic infants may later develop hearing, visual, or neurodevelopmental impairments. This study aimed to evaluate the impact of cCMV infection on newborns' hearing function with a particular emphasis on progressive and late-onset cases.

METHODS

This study is a retrospective chart analysis with longitudinal character and was conducted in two Italian centers: Center 1 (from 1 November 2007 to 31 December 2021) and Center 2 (from 1 January 2012 to 31 December 2021). Data collected included newborn hearing screening results, characterization of hearing loss (unilateral/bilateral, degree of impairment), and audiological follow-up.

RESULTS

The cohort consisted of 103 children (42% males, 58% females). In total, 28 children presented with hearing impairment; 71.4% (20 out of 28) of the cases of hearing loss were severe/profound, with 35.7% of the cases due to unilateral hearing loss. Out of twenty-eight, six experienced progression of hearing loss and four had late-onset hearing loss.

CONCLUSIONS

In the absence of universal cCMV screening, hearing screening at birth for cCMV remains a critical factor for early diagnosis. A significant percentage of children affected by cCMV with normal audiological evaluations at birth is easily lost to follow-up. Close collaboration between neonatologists, pediatricians, and audiological services is fundamental to ensure timely diagnosis and treatment of cCMV-related hearing loss.

Italian validation of the Penn Acoustic Neuroma Quality of Life Scale (PANQOL-It)

Objective

translate and validate the Penn Acoustic Neuroma Quality of Life Scale into Italian language (PANQOL-It).

Methods

the instrument was translated and psychometric properties were subsequently assessed by administering the PANQOL-It to 124 outpatients together with the Depression Anxiety Stress Scale (DASS21) and the Understanding and Communicating domain of the World Health Organization Disability Assessment Schedule II (WHODAS II-D1). The internal consistency, test-retest reliability, construct and criterion-related validity were assessed.

Results

Cronbach's alpha coefficient was 0.92 for the total score and ranged from 0.44 to 0.90 in the seven domains. Significant test-retest reliability was observed (intraclass-correlation = 0.75; p < 0.01). Moderate correlation was reported between facial dysfunction domain and objective facial involvement (p < 0.01). Moderate to strong correlations were observed between anxiety, general health domains and all subscales of the DASS21, and between WHODAS II-D1 and general health and energy domains (p < 0.01). These latter results indicated good construct and criterion-related validity respectively.

Conclusions

PANQOL-It presented more than acceptable psychometric properties and its adoption is justified for both clinical and research purposes.

The Role of Primary Mitochondrial Disorders in Hearing Impairment: An Overview

Background. Defects of mitochondrial DNA (mtDNA) involved in the function of the mitochondrial electron transport chain can result in primary mitochondrial diseases (PMDs). Various features can influence the phenotypes of different PMDs, with relevant consequences on clinical presentation, including the presence of hearing impairment. This paper aims to describe the hearing loss related to different PMDs, and when possible, their phenotype. Methods. A systematic review was performed according to PRISMA guidelines, searching Medline until December 2022. A total of 485 papers were identified, and based on specified criteria, 7 were included in this study. Results. A total of 759 patients affected by PMDs and hearing loss were included. The age of patients ranged from 2 days to 78 years old, and the male-to-female ratio was 1.3:1. The percentage of subjects affected by hearing loss was 40.8%, (310/759), and in most cases, hearing impairment was described as sensorineural, bilateral, symmetrical, and progressive, with different presentations depending on age and syndrome severity. Conclusions. PMDs are challenging conditions with different clinical phenotypes. Hearing loss, especially when bilateral and progressive, may represent a red flag; its association with other systemic disorders (particularly neuromuscular, ocular, and endocrine) should alert clinicians, and confirmation via genetic testing is mandatory nowadays.

Physical Therapy for Benign Positional Vertigo of Posterior Canal: The Role of Alternated Epley and Semont Maneuvers

OBJECTIVE

To investigate if alternated Epley (EP) and Semont (ST) maneuvers could be more effective than repetition of the same in benign paroxysmal positional vertigo of posterior semicircular canal (pBPPV).

DESIGN

We retrospectively reviewed the outcome of pBPPV patients treated with a second maneuver for the persistence of positional nystagmus.

STUDY SAMPLE

Forty-seven patients underwent 2 STs, 64 with 2 EPs, and 71 EPs followed by ST. Videonystagmography and Dizziness Handicap Inventory (DHI) questionnaire were performed.

RESULTS

Absence of positional nystagmus was achieved after 2 maneuvers in 136 patients with pBPPV: 65.9% in the ST group, 70.3% in the EP group, and 84.5% in the EP-ST group. Alternated EP and ST were significantly more effective than repeated ST (P = .03), while we found no significant difference when compared with repeated EP (P = .07). At 1-month follow-up, 12 patients showed persistent positional nystagmus without difference between groups. After 1 month, the 46 patients with negative outcome had significantly higher DHI values (P = .01) than other 136 patients with pBPPV.

CONCLUSIONS

Alternated EP and ST seemed more effective than repeating the same maneuver in treating pBPPV, and this should be confirmed in prospective clinical studies. Resolution of nystagmus after maneuvers was fundamental to reduce handicap deriving from dizziness as reported in DHI.

Validity of the Italian adaptation of the Hearing Handicap Inventory for the Elderly (HHIE-It)

Objective

The aim of this study was to assess the validity and reliability of the Italian translation of the Hearing Handicap Inventory for the Elderly (HHIE).

Methods

A sample of 275 adults, aged > 65 years, filled out the Italian version of the HHIE (HHIE-It) together with the MOS 36-Item Short Form Health Survey (SF-36). Seventy-one participants answered the questionnaire a second time after six weeks. The internal consistency, test-retest reliability, construct and criterion validity were evaluated.

Results

Cronbach's alpha was 0.94 and suggested a high internal consistency. There was also a significant intraclass correlation coefficient (ICC) between test and retest scores. In addition, Pearson's correlation coefficient between the two scores was high and significant. High and significant correlation coefficients were also found between the HHIE-It score and the pure tone average threshold of the better ear and between the HHIE-It and the subscales Role-emotional, Social Functioning and Vitality of the SF-36. These latter results indicate good construct and criterion validity, respectively.

Conclusions

The HHIE-It maintained the reliability and validity of the English version suggesting its utility for both clinical and research purposes.

Monitoring of Auditory Function in Newborns of Women Infected by SARS-CoV-2 during Pregnancy

BACKGROUND

Gestational SARS-CoV-2 infection can impact maternal and neonatal health. The virus has also been reported to cause newborn sensorineural hearing loss, but its consequences for the auditory system are not fully understood.

OBJECTIVE

The aim of this study was to evaluate the impact of maternal SARS-CoV-2 infection during pregnancy on newborn' hearing function during the first year of life.

METHODS

An observational study was conducted from 1 November 2020 to 30 November 2021 at University Modena Hospital. All newborns whose mother had been infected by SARS-CoV-2 during pregnancy were enrolled and underwent audiological evaluation at birth and at 1 year of age.

RESULTS

A total of 119 neonates were born from mothers infected by SARS-CoV-2 during pregnancy. At birth, five newborns (4.2%) presented an increased threshold of ABR (Auditory Brainstem Evoked Response), but the results were confirmed only in 1.6% of cases, when repeated 1 month later, while the ABR thresholds in all other children returned to normal limits. At the 1-year follow-up, no cases of moderate or severe hearing loss were observed, while concomitant disorders of the middle ear were frequently observed.

CONCLUSIONS

Maternal SARS-CoV-2 infection, regardless of the trimester in which it was contracted, appears not to induce moderate or severe hearing loss in infants. It is important to clarify the possible effect of the virus on late-onset hearing loss and future research is needed.

Negative Outcome of Temporalis Fascia Graft in Tympanoplasty with Excessive Bleeding: A Retrospective Study

Background and Objectives: Non-autologous graft materials hold promise for tympanic membrane (TM) perforation closure. In the present manuscript, we aimed to evaluate the influence of clinical and surgical (i.e., graft materials) characteristics on tympanoplasty outcome in chronic otitis media (COM). Materials and Methods: We retrospectively reviewed clinical and surgical characteristics of COM patients with TM perforation treated with tympanoplasty and mastoidectomy. Univariate and multivariate appropriate tests were applied. Results: We used xenograft (porcine submucosal collagen) in 163 patients, and temporalis fascia in 210. The mean follow-up time was 37.2 months. Postoperative TM perforation (i.e., negative outcome) was detected in 11.6% of cases with xenograft, and in 12.8% with temporalis fascia. Performing uni- and multivariate analysis, we determined that large (three or all quadrants) TM perforation (p = 0.04) and moderate-to-severe intraoperative bleeding (p = 0.03) were independent prognostic factors of negative outcome. Considering the 197 patients with moderate-to-severe intraoperative bleeding, we disclosed that the use of temporalis fascia (p = 0.03) was an independent risk factor of postoperative TM perforation. Conclusions: According to our results, large TM perforation and moderate-to-severe intraoperative bleeding were independent prognostic factors of negative outcome in adult COM patients treated with tympanoplasty. In the sub-group of COM patients with excessive intraoperative bleeding, use of temporalis fascia was associated with negative outcome; these patients could benefit from xenograft materials. These findings should be tested in large randomized clinical trials.

From Hype To Reality: A Narrative Review on the Promising Role of Artificial Intelligence in Larynx Cancer Detection and Transoral Microsurgery

Early larynx cancer detection plays a crucial role in improving treatment outcomes and recent studies have shown promising results in using artificial intelligence for larynx cancer detection. Artificial intelligence also has the potential to enhance transoral larynx microsurgery. This narrative review summarizes the current evidence regarding its use in larynx cancer detection and potential applications in transoral larynx microsurgery. The utilization of artificial intelligence in larynx cancer detection with white light endoscopy and narrow-band imaging helps improve diagnostic accuracy and efficiency. It can also potentially enhance transoral larynx microsurgery by aiding surgeons in real-time decision-making and minimizing the risk of complications. However, further prospective studies are warranted to validate the findings, and additional research is necessary to optimize the integration of artificial intelligence in our clinical practice.

Cochlear Implantation Following Transcanal Infrapromontorial Approach for Vestibular Schwannoma: A Case Series

Background: Cochlear implantation (CI) following endoscopic transcanal infrapromontorial vestibular schwannoma (VS) dissection is a feasible intervention in intracanalicular VS, with minimal extension into the cerebellopontine angle, but no audiologic results have ever been reported in the literature. Methods: From 2015 to 2021 in the Otorhynolaryngology Departments of Modena and Verona, three patients underwent this intervention. All were suffering from sporadic left-sided intracanalicular Koos I VS. Intraoperative electrically evoked auditory brainstem responses and electrophysiological measurements were performed before and after the placement of the electrode array, respectively. Since device activation one month after the surgery, each patient was followed up with audiometric tests, data logging, electrode impedance measurements and neural response telemetry performed at each scheduled fitting session at 15 days and 3, 6, 12 and 24 months. Results: Only in patient No. 3, an auditory benefit was observed and still evident even 36 months after activation. Impedances increased progressively in patient No. 1 and a benefit was never reported. Patient No. 2 left the follow-up for worsening comorbidities. Conclusions: CI following transcanal infrapromontorial VS resection is a beneficial intervention. The residual cochlear nerve after the tumour dissection and the course of electrophysiological measurements in the postoperative period were the main predictive factors for audiological outcomes.

Psychological Profile and Social Behaviors of Patients with Hyperacusis

Increased noise sensitivity refers to the abnormal subjective response to external sounds, with a prevalence of between 8% and 15.2% in the adult population as suggested by epidemiological studies. The basic neural mechanism of hyperacusis still remains obscure, so therapies for this often-devastating symptom remain elusive. The aim of this study was to assess psychological profiles in patients with presbycusis without tinnitus in a perspective case-control design. All subjects were initially submitted to audiological evaluation (tympanometry, recordings of the acoustic reflex thresholds, pure tone audiometry) and subsequently were administered the following questionnaires: the hyperacusis questionnaire (HQ), the brief symptom inventory (BSI), and the modified somatic perception questionnaire (MSPQ). Patients with hyperacusis reported a total score and subscales (attentional, social, and emotional) of the HQ significantly higher than controls. They also reported higher scores of the MSPQ and significantly higher mean values with concern to the somatization, obsessive-compulsive, interpersonal sensitivity, depression, and anxiety subscales of the BSI. These results show that psychological distress, as expressed by higher level of somatic attention, somatization, anxiety, and depression, is a significant factor to consider for a complete diagnosis and effective treatment of hyperacusis. For a correct diagnosis of patients seeking help for hyperacusis, their psychological distress should also be assessed, regardless of their hearing abilities. Further studies are required to investigate the pathological mechanisms that are involved in the onset of hyperacusis in patients with normal hearing and those with sensorineural hearing loss.

The Effect of the Use of Hearing Aids in Elders: Perspectives

Older adults with hearing loss have difficulties during conversation with others because an elevated auditory threshold reduces speech intelligibility, especially in noisy environments. Listening and comprehension often become exhausting tasks for hearing-impaired elders, resulting in social isolation and depression. The aim of the present study was to investigate the advantages of hearing aid use in relation to relief from listening-related fatigue, which is still controversial. Participants included a sample of 49 hearing-impaired elders affected by presbycusis for whom hearing aids were prescribed. The Modified Fatigue Impact Scale was used to assess cognitive, physical and psychosocial fatigue. The vitality subscale of the Short Form Health Survey 36 and a single item of the multi-dimensional Speech, Spatial and Quality Hearing Scale (“Do you have to put a lot of effort to hear what is being said in conversation with others?”) were also used. The Cognitive Failures Questionnaire was used to investigate daily errors related to lack of memory and reduced mindedness. Hearing aids rehabilitation resulted in improved speech intelligibility in competing noise, and a significant reduction in cognitive and psychosocial fatigue and listening effort in conversation. Vitality was also improved and a significant reduction in the Cognitive Failures Questionnaire scores was observed. Findings from the study indicate that the use of hearing aids in older impaired-listeners provide them not only with an increased auditory function but also with a reduction in listening-related fatigue and mindedness.

Occlusal splint therapy in patients with Ménière's disease and temporomandibular joint disorder

Objective

This retrospective study aimed to verify the outcomes of stabilising occlusal splint therapy prescribed to 22 patients with unilateral definite Ménière’s disease and comorbid temporomandibular joint disorder.

Methods

The results of a battery of audiometric and vestibular tests were recorded before and after 6 months of treatment, as well as the scores of disease-specific questionnaires.

Results

The average hearing threshold in the affected ear and the acoustic immittance were unchanged. No spontaneous and positional nystagmus were recorded. Caloric hypo-responsiveness and vestibular myogenic evoked responses did not vary. No changes of stabilometric body sway parameters in eyes opened condition and with optokinetic stimulation delivered to the unaffected labyrinth were observed. A significant reduction was recorded in eyes closed condition and with the optokinetic stimulation toward the affected ear. The Tinnitus Handicap Inventory, the Situational Vertigo Questionnaire and the Numeric Pain Rating Scale scores improved. The number of vertigo attacks was reduced.

Conclusions

Occlusal splint therapy is a favourable option to reduce aural symptoms of Ménière’s disease and comorbid temporomandibular joint disorder, even if its pathophysiological mechanism remains elusive.

Endoscopic Anatomy of the Chorda Tympani: Systematic Dissection, Novel Anatomic Classification, and Surgical Implications

HYPOTHESIS

A transcanal endoscopic approach enables visualization of the variable course of the chorda tympani inside the middle ear.

BACKGROUND

The chorda tympani is the longest intrapetrous branch of the facial nerve. Despite having been investigated in several studies, a description of its tympanic tract from an endoscopic point of view is lacking in the literature.

METHODS

We performed transcanal endoscopic dissections of 44 human cadaveric head and ear specimens. The entry point of the chorda tympani into the middle ear was classified into four categories according to its location, and as covered or dehiscent according to its appearance. The chordal eminence (CE) was defined as absent, shallow, intermediate, prominent, or fused, based on its shape and extension. The relationship of the chorda tympani to adjacent bony and ligamental structures was assessed.

RESULTS

The tympanic tract of the chorda tympani was divided into three portions. The periannular segment was dehiscent in 54.5% of specimens, with type II being the most frequent entry point configuration (52.3%). In the interossicular segment, the nerve consistently passed lateral to the incus and medial to the malleus. The course of the intrapetrous segment was independent from the conformation of the tensor fold and supratubal recess.

CONCLUSION

The transcanal endoscopic approach allows a detailed description of tympanic segment of the chorda tympani. Novel anatomic classifications of the chorda tympani and CE are proposed herein to highlight their possible surgical implications during otologic procedures.

Quality of life in vestibular schwannoma: a comparison of three surgical techniques

OBJECTIVE

Through years, interest in quality of life (QoL) among patients affected by vestibular schwannoma (VS) has increased. The expansion of the indications for endoscopic ear surgery allowed the development of the transcanal transpromontorial surgery (TTS) for VS removal. The objective of the present study was to assess QoL in a cohort of VS patients operated on by translabyrinthine (TL), retrosigmoid (RS) and TTS approach.

METHODS

The study was conducted on 111 patients who underwent surgery for VS between January 2017 and January 2020 at two different institutions. Patients fulfilled three questionnaires during follow-up: Glasgow Benefit Inventory, Depression Anxiety Stress Scales-21 and Penn Acoustic Neuroma Quality-Of-Life. The association between sex, age, date of surgery, tumor size, post-operative facial nerve (FN) function and QoL outcomes was assessed.

RESULTS

An overall subjective impairment was demonstrated in all groups. Age, Koos staging and FN functions were associated to distinct QoL outcomes.

CONCLUSIONS

QoL decreases in patients surgically treated for VS. The TTS may allow improved scores in many domains, confirming to be a subjectively well-tolerated technique.

Unexpected hearing improvement after treatment with valganciclovir in a child with congenital cytomegalovirus infection

A 32-week preterm-born male with symptomatic congenital cytomegalovirus infection was treated with valganciclovir. He was also affected by congenital severe bilateral hearing loss and, unexpectedly, a normalization of the hearing threshold was reached at one year of age. The improvement of hearing level in relationship with both the late development of the auditory system and the administration of antiviral therapy is discussed. This case also highlights the importance of early diagnosis of congenital cytomegalovirus associated with close follow-up.

The Atopy Index Inventory: A Brief and Simple Tool to Identify Atopic Patients

INTRODUCTION

Atopy and ear, nose and throat (ENT) diseases are frequently associated; however, no clinical tool has been proposed so far to discriminate which patients could be atopic and therefore deserving of a further immunoallergological evaluation.

OBJECTIVE

The aim of this study was to assess and validate a set of dichotomous responses suitable for predicting the presence of atopy in adult patients.

METHODS

An 11-item questionnaire, i.e., the Atopy Index Inventory (AII), comprised of 4 questions regarding the clinical history for allergic disease and 7 questions evaluating the presence of the most frequent clinical signs affecting allergic patients, was developed and administered to 226 adult subjects (124 atopic subjects and 102 healthy, not atopic subjects). The atopic condition was proven by an immunoallergological evaluation according to the diagnostic criteria of the EAACI guidelines. Internal consistency and clinical validity were tested.

RESULTS

In healthy subjects, the first 4 variables of the AII returned a 100% correct response (all answered "no") and were defined as "decisive" responses. In the logistic regression analysis, when decisive items were negative, the atopic condition was confirmed when answering "yes" to at least 3 "probability" items (cut-off = 2.69). The difference in AII scores between allergic and healthy group was significant using the Mann-Whitney U test (p < 0.0001). The sensitivity and specificity of the AII were 0.97 and 0.91, respectively, with a true predictive value of 0.92 and a false predictive value of 0.97. The ROC curve showed an area of 0.94, with an OR of 0.88 (95% CI 0.87-0.97, p = 0.0001). The internal consistency as determined by the Cronbach α coefficient was 0.88.

CONCLUSION

The AII has been proven to be a brief, simple and sufficiently accurate tool for screening ENT patients in search of atopic individuals and to allow their clinical management.

Evaluation of Performance and Tolerability of Nebulized Hyaluronic Acid Nasal Hypertonic Solution in the Treatment of Chronic Rhinosinusitis

BACKGROUND

Nasal solutions are part of the recommended therapy of chronic rhinosinusitis (CRS). Formulations containing hyaluronic acid (HA) may represent a promising topical treatment in CRS patients in light of the anti-inflammatory and protective effect of HA on the sinonasal mucosa.

OBJECTIVE

Primary aim was to evaluate the performance of a new nebulized HA nasal hypertonic solution in the relief of symptoms of CRS. Secondarily, evaluation of symptoms improvement, endoscopic nasal findings, and safety profile were assessed.

METHODS

A monocenter, single arm, not controlled, premarket clinical trial on a new nasal solution containing HA was performed. All the included patients had a history of previously diagnosed or recurrent CRS or they had received a clinical diagnosis of CRS defined, according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2012. Each patient was evaluated on 3 visits. Endoscopic nasal examination and Nasal Obstruction Symptom Evaluation Instrument questionnaire filling were performed during each visit. Patients' adherence to treatment and overall satisfaction, patients' and investigator's global evaluation of performance, and safety parameters were also assessed.

RESULTS

Eighty patients were enrolled. The use of the investigated HA nasal solution revealed to be significantly effective in the relief of symptoms of CRS. According to daily patients' diaries, several signs and symptoms significantly improved after therapy. The comparison between endoscopic assessments before and after treatment confirmed improvement of the condition in at least 75% of patients. Seventy-four percent of the patients were quite or very satisfied with the treatment and 80% reported an improvement. The investigator's global assessment of performance was in agreement with this view, as more than 80% of the patients were considered clinically improved.

CONCLUSIONS

The use of the investigated new nebulized HA nasal hypertonic solution is an effective and safe the treatment of CRS.

Different Audiologic Outcomes in Twins with Congenital Cytomegalovirus Infection

Congenital cytomegalovirus (cCMV) infection is a major cause of hearing loss in children. A few cases of cCMV twin pregnancies are reported in the literature. Twins can react differently to maternal infection, but hearing loss is rarely evaluated. Two couples of twins with cCMV infection and different audiologic outcomes are reported. The first couple of twins was composed by two male twins, both affected by cCMV infection. The first born had normal hearing function, and the second born had sensorineural hearing loss (SNHL). In the second couple, a male and a female twin, only the male twin was affected by cCMV infection, and both had normal hearing function. In this case series, an interesting finding was the association between the presence of viral DNA in liquor and hearing loss in one newborn. Further research is needed to better understand the pathophysiology of SNHL caused by cCMV infection.

The psychometric properties of the Italian adaptation of the Health Orientation Scale (HOS)

Background

A novel approach suggested that cognitive and dispositional features may explain in depth the health behaviors adoption and the adherence to prevention programs. The Health Orientation Scale (HOS) has been extensively used to map the adoption of health and unhealthy behaviors according to cognitive and dispositional features. Coherently, the main aim of the current research was to assess the factor structure of the Italian version of the HOS using exploratory and confirmatory factor analysis and testing the construct validity of the scale by assessing differences in health orientations between tobacco cigarette smokers and nonsmokers.

Method

The research protocol was organized in two studies. Study 1 evaluated the dimensionality of the HOS in a sample of Northern Italian healthy people. Three hundred and twenty-one participants were enrolled; they were 229 women (71.3%) and 92 men (28.7%). In Study 2, the factor structure and construct validity of the HOS Italian version was assessed trough confirmatory factor analysis using a tobacco cigarette smokers and nonsmokers population. Two hundred and nineteen participants were enrolled; they were 164 women (75.2%) and 55 men (24.8%).

Results

In Study 1, a seven factors solution was obtained explaining 60% of cumulative variance instead of 10 factors solution of the original version of the HOS. In Study 2, the factor structure of the Italian version of the HOS was confirmed and applied to the smokers and nonsmokers; nonsmokers reported higher values than smokers in Factor 1 (MHPP) [t (208) = − 2.739 p < .007] (CI 95–4.96% to −.809), Factor 2 (HES) [t (209) = − 3.387 p < .001] (CI 95–3.93% to -. 1.03), Factor 3 (HIC) [t(213) = − 2.468 p < .014] (CI 95–2.56% to −.28) and Factor 7 (HEX) [t(217) = − 3.451 p < .001] (CI 95%- 1.45 to .39).

Conclusions

Results of the Italian adaptation of HOS lead to a partial redistribution of items and confirmed 7 subscales to distinguish psycho-cognitive dispositional dimensions involved in health orientation styles.

A case-control study of visually evoked postural responses in childhood with primary headaches

BACKGROUND

Disorientation, nausea, confusion, dizziness, and displacement are frequently complained by headache-suffering children. Anyhow, the cause of these symptoms is still unclear, and a dysfunction of vestibular pathways or their alteration due to central pain pathways hyper-activation, has been proposed. The aim of this study is to use posturography to explore the balance function of headache-suffering children during pain-free periods.

METHODS

Posturography was performed on 19 migraineurs, 11 tension-type headache sufferers, and 20 healthy controls. Posturographic measures were performed during headache-free periods under different conditions: with eyes opened, eyes closed, and during right and left optokinetic stimulation. The last 2 conditions were used to mimic unreliable visual signals that can confound vestibular system.

RESULTS

During eyes-closed conditions, headache-suffering children displayed higher displacements than healthy controls, since statokinesiogram surface was higher in tension-type headache sufferers and migraineurs compared with controls (P value = 0.0095). Romberg's index, indicating the overall stability of the subject, was lower in healthy controls than in headache sufferers (P = 0.0139), thus suggesting a vestibular impairment in the seconds. Moreover, both during right and left optokinetic stimulation, the statokinesiogram length was higher in headache-suffering children (P < 0.0001). Thereafter, statokinesiogram surface was higher in migraineurs during right optokinetic stimulation (P = 0.0388) than in tension-type headache sufferers when stimulation was directed on the opposite side (P = 0.0249).

CONCLUSIONS

These results suggest a central alteration of vestibular pathways in headache-suffering children, that makes balance function more dependent from visual inputs than healthy subjects, even in inter-ictal phases.

Gusher in stapes surgery: a systematic review

OBJECTIVE

The aim of this study is to perform a systematic literature review on the occurrence of gusher during stapes surgery, to understand its surgical management and outcomes.

METHODS

The PRISMA standard was applied to identify English, Italian or French-language studies, related to stapes surgery and mentioning gusher or perilymphatic leak. Full-texts lacking information on the management of gusher and/or the post-operative hearing outcome were excluded.

RESULTS

Twenty-four articles were eventually included. Seventy-six patients were involved in the qualitative synthesis. The management of gusher mostly consisted in covering the oval window and/or filling the tympanic cavity, with absorbable and autologous graft materials. Packing of the external auditory canal was reported in 51 patients (67%). Gusher was related to complete/profound loss of hearing in 25% of the cases and to a worsening of hearing function in 31% of patients. In 19% of patients an improvement in hearing tests was reported; in 28% the hearing function was unchanged. Post-operative vestibular symptoms were reported in 7 patients, and were mainly mild and transient. The absence of vestibular symptoms was underlined in 9 cases, while in 79% of the patients the authors did not provide information.

CONCLUSION

The unexpected occurrence of gusher during stapes surgery represents a relevant issue for the otologic surgeon. Its management most commonly consists in plugging the oval window and the tympanic cavity. In most of the cases, a stapes prosthesis could be positioned. The results on hearing and vestibular functions are widely variable.

Are periodontal outcomes affected by personality patterns? A 18-month follow-up study

OBJECTIVES

This research aims to study the relationship between personality traits and periodontal clinical outcomes by taking into account the level of anxiety and depression, periodontal health and oral hygiene behaviour of patients affected with gingivitis or moderate periodontitis requiring periodontal therapy.

MATERIAL AND METHODS

The periodontal data of 40 systemically healthy patients affected by gingivitis or moderate periodontitis were collected at baseline and 18 months later. The psychological variables, dental awareness and adherence intent of the patients were assessed through questionnaires, and only those patients that exhibited a higher degree of compliance were included in the study. The personality traits (cluster A: paranoid, schizoid, schizotypal; cluster B: borderline, antisocial, narcissistic, and histrionic; cluster C: avoidant, dependent, and obsessive-compulsive) and the level of anxiety and depression of the patients were assessed. Patients were instructed with oral hygiene measures and were treated with periodontal therapy.

RESULTS

Clusters A and B showed a consistent tendency for reduced levels of oral hygiene (increased full-mouth plaque score - FMPS). The results from cluster B were found to be significantly related to deep periodontal pockets at baseline. On the contrary, cluster C seemed to be linked to clinically better indices, particularly in terms of full-mouth-bleeding-score and pocket depth, both at baseline and 18 months later. The results collected from clusters B and C were directly correlated with anxiety, depression and FMPS. Moreover, anxiety was directly correlated with the patient's need for professional oral-care.

CONCLUSIONS

Personality traits appear to play a significant role in determining the therapeutic outcomes of periodontal therapy in themselves. Thus, it is ideal for several important psychological, affective or behavioural factors to be associated with various personality traits so as to orient the outcome of periodontal therapy.

Changes in physical activity among coronary and hypertensive patients: A longitudinal study using the Health Action Process Approach

OBJECTIVES

Physical activity (PA) is a key factor in cardiovascular disease prevention. Through the Health Action Process Approach (HAPA), the present study investigated the process of change in PA in coronary patients (CPs) and hypertensive patients (HPs).

DESIGN

Longitudinal survey study with two follow-up assessments at 6 and 12 months on 188 CPs and 169 HPs.

MAIN OUTCOME MEASURES

Intensity and frequency of PA.

RESULTS

A multi-sample analysis indicated the equivalence of almost all the HAPA social cognitive patterns for both patient populations. A latent growth curve model showed strong interrelations among intercepts and slopes of PA, planning and maintenance self-efficacy, but change in planning was not associated with change in PA. Moreover, increase in PA was associated with the value of planning and maintenance self-efficacy reached at the last follow-up Conclusions: These findings shed light on mechanisms often neglected by the HAPA literature, suggesting reciprocal relationships between PA and its predictors that could define a plausible virtuous circle within the HAPA volitional phase. Moreover, the HAPA social cognitive patterns are essentially identical for patients who had a coronary event (i.e. CPs) and individuals who are at high risk for a coronary event (i.e. HPs).

Posturographic destabilization in eating disorders in female patients exposed to body image related phobic stimuli

Human postural control is dependent on the central integration of vestibular, visual and proprioceptive inputs. Psychological states can affect balance control: anxiety, in particular, has been shown to influence balance mediated by visual stimuli. We hypothesized that patients with eating disorders would show postural destabilization when exposed to their image in a mirror and to the image of a fashion model representing their body ideal in comparison to body neutral stimuli. Seventeen females patients attending a day centre for the treatment of eating disorders were administered psychometric measures of body dissatisfaction, anxiety, depression and underwent posturographic measures with their eyes closed, open, watching a neutral stimulus, while exposed to a full length mirror and to an image of a fashion model corresponding to their body image. Results were compared to those obtained by eighteen healthy subjects. Eating disordered patients showed higher levels of body dissatisfaction and higher postural destabilization than controls, but this was limited to the conditions in which they were exposed to their mirror image or a fashion model image. Postural destabilization under these conditions correlated with measures of body dissatisfaction. In eating disordered patients, body related stimuli seem to act as phobic stimuli in the posturographic paradigm used. If confirmed, this has the potential to be developed for diagnostic and therapeutic purposes.

Cognitive vulnerability to depressive symptoms in children: the protective role of self-efficacy beliefs in a multi-wave longitudinal study

The current multi-wave longitudinal study on childhood examined the role that social and academic self-efficacy beliefs and cognitive vulnerabilities play in predicting depressive symptoms in response to elevations in idiographic stressors. Children (N = 554; males: 51.4 %) attending second and third grade completed measures of depressive symptoms, negative cognitive styles, negative life events, and academic and social self-efficacy beliefs at four time-points over 6 months. Results showed that high levels of academic and social self-efficacy beliefs predicted lower levels of depressive symptoms, whereas negative cognitive styles about consequences predicted higher depression. Furthermore, children reporting higher social self-efficacy beliefs showed a smaller elevation in levels of depressive symptoms when reporting an increases in stress than children with lower social self-efficacy beliefs. Findings point to the role of multiple factors in predicting children's depression in the long term and commend the promotion of self-efficacy beliefs and the modification of cognitive dysfunctional styles as relevant protective factors.

A preliminary study on the relationship between central auditory processing and childhood primary headaches in the intercritical phase

BACKGROUND

Recently, an increasing number of articles have appeared on central auditory processing disorders, but in the literature there is only one study that evaluated the possible correlation between migraine in the critical phase and central auditory processing. The aim of our study was to assess the correlation between auditory processing information and childhood primary headaches in the intercritical phase.

METHODS

This is an observational study. We enrolled 54 patients, 30 with primary headache (migraine and tension headache) and 24 normal controls, matched for sex and age. The mean age at first observation was 9 years 10 months; the duration of observational follow-up was 2 years. Both groups had normal audiological and neurological profiles, normal peripheral hearing acuity and normal cognitive and behavioral skills. We excluded patients who had undergone pharmacological prophylactic treatment for headaches in the 6 months preceding the study and subjects with a frequency of headache lower than one every two months. After enrolment, both groups were analyzed with a computerized test battery for Speech Perception Tests in silence and in noise background to assess speech perception disabilities. In addition, with a test battery of Speech Perception Tests, we compared patients with migraines and tension-type headaches. The non-parametric χ2 test, the Mann-Whitney U-test and the Wilcoxon signed ranks test were used for statistical analysis. P-values <0.05 were considered significant and STATA 10 software was used for statistical analyses.

RESULTS

Our results showed that patients with primary headache (migraine and tension-type headache), had a deficit of auditory processing in noisy background compared to control cases, but we found no significant differences when we compared patients with migraine and tension-type headache.

CONCLUSIONS

This is a work in progress and further studies are needed to assess the relationship between the impairment of auditory processing and primary headache, not only to improve the diagnostic approach to primary headache, but also to improve therapeutic intervention.

A Psychometric Evaluation of the Group Environment Questionnaire in a Sample of Professional Basketball and Soccer Players

Psychometric properties of the Group Environment Questionnaire were investigated in a large sample of soccer ( n = 222) and professional basketball players ( n = 375). Confirmatory factor analysis was performed both on the total sample and on the two subsamples through a multi-group approach; associations between cohesion and the duration of belonging to the team were also explored. Results confirmed the four-factor structure proposed by Carron's original model even though some items with low loadings were eliminated. No significant associations were found between team cohesion and the duration of belonging to the team.

Effect of a fixed combination of nimodipine and betahistine versus betahistine as monotherapy in the long-term treatment of Ménière's disease: a 10-year experience

Despite an abundance of long-term pharmacological treatments for recurrent vertigo attacks due to Ménière's disease, there is no general agreement on the their efficacy. We present the results of a retrospective study based on a 10-year experience with two long-term medical protocols prescribed to patients affected by Ménière's disease (diagnosed according to the American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium guidelines) who completed treatments in the period 1999-2009. A total of 113 medical records were analysed; 53 patients received betahistine-dihydrochloride at on-label dosage (32 mg die) for six months, and 60 patients were treated with the same regimen and nimodipine (40 mg die) as an add-therapy during the same period. Nimodipine, a 1,4-dihydropyridine that selectively blocks L-type voltage-sensitive calcium channels, has previously been tested as a monotherapy for recurrent vertigo of labyrinthine origin in a multinational, double-blind study with positive results. A moderate reduction of the impact of vertigo on quality of life (as assessed by the Dizziness Handicap Inventory) was obtained in patients after therapy with betahistine (p < 0.05), but a more significant effect was achieved in patients treated by combined therapy (p < 0.005). In the latter group, better control of vertigo was seen with a greater reduction of frequency of attacks (p < 0.005). Both protocols resulted in a significant improvement of static postural control, although a larger effect on body sway area in all tests was obtained by the fixed combination of drugs. In contrast, no beneficial effect on either tinnitus annoyance (as assessed by the Tinnitus Handicap Inventory) and hearing loss (pure-tone average at 0.5, 1, 2, 3 kHz frequencies of the affected ear) was recorded in patients treated with betahistine as monotherapy (p > 0.05), whereas the fixed combination of betahistine and nimodipine was associated with a significant reduction of tinnitus annoyance and improvement of hearing loss (p < 0.005). It was concluded that nimodipine represents not only a valid add-therapy for Ménière's disease, and that it may also exert a specific effect on inner ear disorders. Further studies to investigate this possibility are needed.

Herpes zoster oticus: a clinical model for a transynaptic, reflex pathways, viral transmission hypotheses

Reactivation of the varicella-zoster virus (VZV) along the sensory nerves innervating the ear, including the geniculate ganglion, is responsible for herpes zoster oticus (HZO). In some cases, HZO is associated with polyneuropathy of the cranial nerves, although the mechanism of this involvement is not known. To explain this phenomenon and based on some clinical considerations, the present authors hypothesize an intersynaptic spread of VZV along the reflex pathways of the brainstem.

Otolaryngology fantastica: the ear, nose, and throat manifestations of Munchausen's syndrome

OBJECTIVES/HYPOTHESIS

Munchausen's syndrome (MS) is a form of severe, chronic, factitious disorder with physical symptoms. Some essential features define MS, such as recurrent, feigned, or simulated illness; peregrination (traveling or wandering); pseudologia fantastica; and drug abuse. Munchausen's syndrome by proxy (MSBP) classically involves a parent or other caregiver who inflicts injury or induces illness in a child. The aim of the present study was to summarize and study the main ear, nose, and throat (ENT) manifestations of MS and MSBP.

STUDY DESIGN

A systematic literature review carried out in a tertiary university referral center.

METHODS

An appropriate string was run on PubMed to retrieve articles dealing with ENT manifestations of MS and MSBP. A double cross-check was performed on citations and full-text articles found using selected inclusion and exclusion criteria.

RESULTS

In total, 24 articles were finally included in the study, describing 30 cases of MS or MSBP involving the ENT region; 15/30 (50%) cases involved the face, most often presenting as facial pain or facial swelling; and 7/30 (23.3%) cases presented with symptoms involving the ear. Six cases out of 30 (20%) were MSBP.

CONCLUSIONS

MS and MSBP may present with symptoms involving the head and neck area, particularly the face and external ear canal. The ENT specialist should suspect MS in patients with strange and long-lasting symptoms, so as to avoid misdiagnosis and unnecessary treatments that waste time and money in the healthcare sector.
