Microvascular Free Flap Outcomes in Maxillectomy Defects from Invasive Fungal Sinusitis. Laryngoscope 2024; 134:1642-1647. [PMID: 37772913 DOI: 10.1002/lary.31081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 09/13/2023] [Indexed: 09/30/2023]
Abstract
OBJECTIVES Microvascular free tissue transfer is routinely used for reconstructing midface defects in patients with malignancy, however, studies regarding reconstructive outcomes in invasive fungal sinusitis (IFS) are lacking. We aim to describe outcomes of free flap reconstruction for IFS defects, determine the optimal time to perform reconstruction, and if anti-fungal medications or other risk factors of an immunocompromised patient population affect reconstructive outcomes. METHODS Retrospective review of reconstruction for IFS (2010-2022). Age, BMI, hemoglobin A1c, number of surgical debridements, and interval from the last debridement to reconstruction were compared between patients with delayed wound healing versus those without. Predictor variables for delayed wound healing and the effect of time on free flap reconstruction were analyzed. RESULTS Twenty-seven patients underwent free flap reconstruction for IFS. Three patients were immunocompromised from leukemia and 21 had diabetes mellitus (DM). Patients underwent an average of four surgical debridements for treatment of IFS. The interval from the last IFS debridement to flap reconstruction was 5.58 months (±5.5). Seven flaps (25.9%) had delayed wound healing. A shorter interval of less than 2 months between the last debridement for IFS and reconstructive free flap procedure was associated with delayed wound healing (Fisher Exact Test p = 0.0062). Other factors including DM, BMI, HgA1c, and bone reconstruction were not associated with delayed wound healing. CONCLUSION Patients with maxillectomy defects from IFS can undergo microvascular-free flap reconstruction with good outcomes while on anti-fungal medication. Early reconstruction in the first 2 months after the last IFS debridement is associated with delayed wound healing. LEVEL OF EVIDENCE 4 Laryngoscope, 134:1642-1647, 2024.

Abstract
Introduction In patients who undergo a total laryngectomy, one of the most common techniques for voice rehabilitation is a tracheoesophageal prosthesis. Typically, this is accomplished using an endoscope down the oesophagus to visualise puncturing of the posterior tracheal wall; however, we present a case in which the use of an endoscope was not feasible, and a novel technique had to be utilised. Case report A mid-70s male who had a total laryngectomy secondary to laryngeal carcinoma was undergoing tracheoesophageal puncture for prosthesis placement, when it was noted that he had significant stenosis of his proximal oesophagus, precluding the use of an endoscope. The senior author decided to use intraoperative ultrasound to visualise the oesophageal lumen for proper placement of the puncture. Discussion This case demonstrates the ability of intraoperative ultrasound to visualise the oesophageal lumen and accurately place the tracheoesophageal puncture in cases where an endoscope cannot be used. Conclusion We present a novel technique in which ultrasound was used to visualise the oesophageal lumen and identify the needle puncturing the posterior tracheal wall for placement of a tracheoesophageal prosthesis.

Abstract
Sialolithiasis is the formation of a stone within the salivary gland, and approximately 80% of them occur within the submandibular gland. Sialolithiasis can lead to swelling and pain of the gland in the immediate phase and if left untreated, can lead to sialadenitis and even atrophy of the gland. Certain factors have already been established in the formation of sialolithiasis such as dehydration, tobacco smoke, autoimmune disorders and certain medications. One factor we theorise contributes to the formation of sialolithiasis is bony outgrowths on the tongue surface of the jaw, called mandibular tori. These outgrowths can lead to external compression of the submandibular duct, which leads to impeded salivary flow and the potential for sialolith formation. We present two cases in which individuals had submandibular sialolithiasis in the setting of extensive mandibular tori.

Abstract
Objective Identify trends in swallowing outcomes in p16+ oropharyngeal squamous cell carcinoma following neoadjuvant chemotherapy+surgery (NAC+S) versus neoadjuvant chemotherapy+surgery+radiation (NAC+S+R). Study Design Cohort study. Setting Single academic institution. Methods Swallowing outcome was measured using a validated questionnaire, MD Anderson Dysphagia Inventory (MDADI). MDADI scores were compared between NAC+S and NAC+S+R groups in short-term (<1 year), middle-term (1-3 years), and long-term (>3 years). Clinical factors associated with MDADI scores were explored using a linear mixed model. Statistical significance was established at p < .05. Results Sixty-seven patients met the inclusion criteria and were divided into 2 groups: NAC+S (57 [85.1%]) and NAC+S+R (10 [14.9%]). All patients had improved MDADI scores in the middle-term compared to short-term (NAC+S: score increase = 3.43, p = .002; NAC+S+R: score increase = 11.18, p = .044), long-term compared to short-term (NAC+S: score increase = 6.97, p < .001; NAC+S+R: score increase = 20.35, p < .001), and long-term compared to middle-term (NAC+S: score increase = 3.54, p = .043; NAC+S+R: score increase = 9.18, p = .026). NAC+S patients had better MDADI scores than NAC+S+R patients at short-term (83.80 vs 71.26, p = .001). There was no significant difference in swallowing function in the middle-term or long-term. Conclusion Regardless of treatment type, swallowing will likely be improved in the middle-term and long-term compared to the short-term. Patients treated with NAC+S+R will have worse short-term swallowing function. However, in the middle-term and long-term, there is no significant difference in swallowing function between patients treated with NAC+S and NAC+S+R.

Enhanced neoepitope-specific immunity following neoadjuvant PD-L1 and TGF-b blockade in HPV-unrelated head and neck cancer. J Clin Invest 2022; 132:161400. [PMID: 35727629 PMCID: PMC9479764 DOI: 10.1172/jci161400] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 06/16/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Head and neck squamous cell carcinoma not associated with human papillomavirus (HPV-unrelated HNSCC) is associated with high rates of recurrence and poor survival. METHODS We conducted a clinical trial in 14 patients with newly diagnosed, HPV-unrelated HNSCC to evaluate the safety and efficacy of neoadjuvant bintrafusp alfa, a bifunctional fusion protein that blocks programmed death-ligand 1 (PD-L1) and neutralizes transforming growth factor-beta (TGF-). RESULTS Bintrafusp alfa was well tolerated, and no treatment-associated surgical delays or complications occurred. Objective pathologic responses were observed and 12 of 14 patients (86%) were alive and disease free at one year. Alterations in regulatory T cell infiltration and spatial distribution relative to proliferating CD8 T cells indicated reversal of Treg immunosuppression in the primary tumor. Detection of neoepitope-specific tumor T cell responses, but not viral-specific responses, correlated with development of a pathologic response. Detection of neoepitope-specific responses and pathologic responses in tumors was not correlated with genomic features or tumor antigenicity but was associated with reduced pre-treatment myeloid cell tumor infiltration. These results indicate that dual PD-L1 and TGF- blockade can safely enhance tumor antigen-specific immunity and highlight the feasibility of multi-mechanism neoadjuvant immunotherapy in patients with HPV-unrelated HNSCC. CONCLUSION Our studies provide new insight into the ability of neoadjuvant immunotherapy to induce polyclonal neoadjuvant-specific T cell responses in tumors and suggest that features of the tumor microenvironment, such as myeloid cell infiltration, may be a major determinant of enhanced anti-tumor immunity following such treatment.

Diagnostic performance of the second-generation molecular tests in the assessment of indeterminate thyroid nodules: A systematic review and meta-analysis. Am J Otolaryngol 2022; 43:103394. [PMID: 35241290 DOI: 10.1016/j.amjoto.2022.103394] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 01/24/2022] [Accepted: 02/13/2022] [Indexed: 11/01/2022]
Abstract
OBJECTIVE The objective of this systematic review and meta-analysis was to evaluate the diagnostic performance of the second-generation molecular tests in the diagnosis of thyroid nodules with indeterminate fine-needle aspiration biopsy results. METHODS We searched PubMed, Google Scholar, Scopus, and Cochrane Library for studies published between January 2017 and March 2021. Inclusion criteria were indeterminate thyroid results from fine-needle aspiration (FNA) that included Bethesda categories III and IV, use of Afirma GSC, Thyroseq v3, and ThyGeNext as an index test, and conclusive histopathological results. Studies with no post-surgical diagnoses were excluded. For each included study, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were obtained. Sensitivity and specificity were pooled jointly using a bivariate binomial random-effects model. Statistical significance was indicated at p-value less than 0.05. RESULTS Our search yielded 431 non-duplicate articles, of which 15 were included in the study (7 GSC, 6 Thyroseq v3, and 2 ThyGeNext). ThyGeNext studies were excluded from the meta-analysis due to the small sample size. Pooled data for GSC studies on 472 thyroid nodules showed a sensitivity of 96.6 (95% confidence interval: 89.7-98.9%), specificity of 52.9% (23.4-80.5%), PPV of 63% (51-74%), and NPV of 96% (94-98%). Pooled data for ThyroSeq studies on 530 thyroid nodules showed a sensitivity of 95.1% (91.1-97.4%), specificity of 49.6% (29.3-70.1%), PPV of 70% (55-83%), and NPV of 92% (86-97%). There was no statistically significant difference in diagnostic performances of the two tests (p-values for sensitivity = 0.89, specificity = 0.82, PPV = 0.43, NPV = 0.17). CONCLUSION High sensitivity and high NPV in GSC and Thyroseq v3 have potential to help rule out malignancy among thyroid nodules with indeterminate cytology results. There was no difference in diagnostic performances between the two molecular tests indicating that either test is appropriate to determine the malignancy of thyroid nodules. Further long-term outcome data are warranted to make a clear recommendation.

Abstract
PURPOSE Office-based procedures in otolaryngology are increasingly utilized to increase efficiency, reduce cost, and eliminate risks associated with surgery. Gland-preserving surgical management of sialadenitis and sialolithiasis are often performed in the operating room, although many surgeons are moving this practice to clinic. We aim to determine the difference in patient charges and perioperative outcomes for salivary gland procedures performed in the clinic versus the OR. METHODS Retrospective series of patients presenting with sialolithiasis, acute or chronic sialadenitis, and stricture between 2010 and 2019. Demographics, perioperative variables, setting, and charge data were collected. RESULTS 528 patients underwent operative intervention (n = 427 office, n = 101 OR). Cohort demographics were comparable. Sialolithiasis was the most common presenting diagnosis in both cohorts. Both cohorts had similar rates of complete (p = 0.09) and partial (p = 0.97) response to treatment. A higher percentage of patients in the OR group reported no improvement (21.4 vs 12.2%, p = 0.034). Overall complications were similar (p = 0.582). Mean charges were statistically greater in the OR ($5560.35 OR vs $1298.33 office, p < 0.001). Operative time was significantly reduced in the office group (21.8 min vs 60.85 min, p < 0.001). CONCLUSIONS Appropriately selected patients can be successfully treated in outpatient clinic without compromising patient safety or quality while significantly reducing the financial burden to patients and the healthcare system.

Abstract
OBJECTIVE Thyroid and parathyroid surgeries are frequently performed with the aid of electromyogram endotracheal tubes. However, the most common adverse events have not been reported comprehensively. This study aimed to summarize the device adverse events, patient complications, and subsequent interventions related to electromyogram endotracheal tubes. METHODS In this retrospective cross-sectional analysis, the US Food and Drug Administration's Manufacturer and User Facility Device Experience database was queried for electromyogram endotracheal tube adverse events between 2010 and 2020. Data were extracted for devices used in thyroid and parathyroid surgery. RESULTS Of 198 included reports, the most common device-related adverse events were loss of response to nerve stimulation (34.8%), cuff perforation (18.2%), and tube lumen obstruction (13.6%). Of 98 patient complications, the most common included ventilation failure (n = 50), airway trauma (n = 22), and recurrent laryngeal nerve injury (n = 5). There was 1 periprocedural death reported. Reported interventions include reintubation performed in 60.1% of all device adverse events, extended hospitalization in 27.3% of airway trauma events, and 5 tracheostomies performed for ventilation failure events. Forty-one events resulted in case delays and 13 events led to aborted cases. The most reported adverse events occurred in 2018 (n = 35) and 2015 (n = 30). CONCLUSIONS The most commonly reported adverse events associated with electromyogram endotracheal tubes include loss of response to nerve stimulation, cuff perforation, ventilation failure, and airway trauma. Subsequent interventions include reintubation, tracheostomy, extended hospitalization, and aborted cases. Surgical teams should consider these adverse events when consenting patients and using these devices in thyroid and parathyroid cases.

Abstract
PURPOSE The present study was developed to evaluate the effectiveness of a simple rapid technique for de-epithelializing cutaneous flaps and grafts in parotidectomy reconstruction. MATERIALS AND METHODS 109 patients who underwent a parotidectomy with abdominal free dermal fat graft (FDFG) reconstruction between 2018 and 2021 were evaluated based on demographic factors, past medical/surgical history, type of parotidectomy performed, operative factors, and post-operative complications. These data were then stratified based on de-epithelialization technique as well as tumor malignancy status to determine any differences in complication rates or perioperative factors between electrocautery (EC) and cold knife (CK) techniques within both benign and malignant subgroups. RESULTS 77 of the 109 participants underwent FDFG de-epithelialization using monopolar electrocautery (EC) and the remaining 32 participants underwent de-epithelialization using traditional cold knife (CK) technique. There was no statistical difference among the two groups in overall complication rate. The EC group had a significantly shorter operation time ("EC vs. CK": 144.2 min vs. 174.7 min; p = 0.031). Additionally, histopathologic samples showed that both techniques left the underlying dermis intact and without damage. CONCLUSIONS This study demonstrated that there is no difference in complication rate or histology of FDFGs de-epithelialized using EC compared to CK. It was also shown that when controlling for confounders by looking solely at the benign subgroup of patients, EC de-epithelialization was a faster technique than CK. These findings suggest that EC is just as effective as CK, and may actually be a more efficient surgical technique to accomplish de-epithelialization of FDFG.

Abstract
OBJECTIVE To evaluate 2-year follow-up swallowing function in patients with human papillomavirus-related oropharyngeal squamous cell carcinoma (HPV+ OPSCC) who completed neoadjuvant chemotherapy and transoral robotic surgery (NAC+S). STUDY DESIGN Retrospective analysis of patients with OPSCC treated with NAC+S between 2010 and 2021. SETTING A single academic institution. METHODS This is a cross-sectional study of patient-reported swallowing function, assessed with the MD Anderson Dysphagia Inventory (MDADI) at least 2 years after completion of treatment. The inclusion criteria are patients with HPV+ OPSCC who underwent NAC+S at least 2 years ago. Those requiring adjuvant radiation or chemoradiation or experiencing relapse were excluded from the study. RESULTS Completed MDADIs were received from 37 patients at a median 3.8 years posttreatment (interquartile range, 2.0-8.6 years). Of those, 94.6% (n = 35) were male and 81.1% (n = 30) were White. The median age at OPSCC diagnosis was 59.0 years (interquartile range, 41-80 years). The most frequent primary subsite of OPSCC was the base of the tongue (n = 20, 54.1%), followed by the tonsils (n = 16, 43.2%). In addition, 75.7% (n = 28) had stage IVa disease (TNM seventh edition), and 29 (78.4%) had scores ≥80, classified as optimal function. When compared with patients who received bilateral neck dissection, patients who received unilateral neck dissection were associated with an age <65 years old (P = .036) and lower clinical TNM stage (P = .04), as well as higher composite, emotional, functional, and physical MDADI scores (P = .017, .046, .013, and .05, respectively). CONCLUSION Patients with OPSCC who were treated with NAC+S achieved satisfactory long-term swallowing outcomes. Unilateral neck dissection was significantly associated with higher MDADI scores in this patient cohort.

Abstract
BACKGROUND Prior to thyroid surgery, a subset of patients chronically uses steroids to manage medical conditions such as Grave's disease, auto-immune conditions, or organ transplantation. Existing literature describes adverse effects of prolonged steroid use on surgical outcomes, however there remains a paucity of data investigating the specific effects of steroid use on postoperative outcomes after thyroidectomy. This study aims to identify complication risks steroid users are predisposed to after thyroidectomy. MATERIALS AND METHODS The American College of Surgeons National Surgical Quality Improvement Program Database (ACS-NSQIP) was queried to identify and isolate all patients who had undergone thyroidectomy procedures by Current Procedure Terminology codes from 2005 through 2018. Univariate analysis was performed to compare steroid uses and non-steroid users. Coarsened exact matching was utilized to homogenize the two cohorts based on demographics and preoperative comorbidities. RESULTS A total of 153,595 thyroidectomies were initially included. After Coarsened exact matching, 116,861 patients were categorized as non-steroid users, and 2,965 as steroid users. The steroid cohort demonstrated significantly higher rates of any complication (P < 0.001) as well as overall surgical, cardiopulmonary, and renal complications. Individual complications such as superficial surgical site infections (P = 0.013), pulmonary embolism (P = 0.016), deep vein thrombosis (P = 0.011), progressive renal insufficiency (P = 0.006), and unplanned readmission (P = 0.026) were also increased. CONCLUSIONS Patients with chronic steroid use undergoing thyroidectomy are at an increased risk for surgical, cardiopulmonary, and renal complications. Further research on preoperative steroid management is necessary for optimizing outcomes in this population.

Abstract
BACKGROUND The oncologic outcomes of surgery alone for patients with American Joint Committee on Cancer 7th edition (AJCC 7th) pN2a and pN2b human papillomavirus-associated oropharynx squamous cell carcinoma (HPV+OPSCC) are not clear. METHODS The authors performed a 12-institution retrospective study of 344 consecutive patients with HPV+OPSCC (AJCC 7th pT0-3 N3 M0) treated with surgery alone with 6 months or more of follow-up using univariate and multivariate analyses. RESULTS The 2-year outcomes for the entire cohort were 91% (182 of 200) disease-free survival (DFS), 100% (200 of 200) disease-specific survival (DSS), and 98% (200 of 204) overall survival (OS). The 18 recurrences within 2 years were 88.9% (16 of 18) local and/or regional recurrences and 11.1% (2 of 18) distant metastases. Recurrences were not significantly associated with smoking, pT stage, or pN stage. The 16 patients with locoregional recurrences within 2 years all underwent successful salvage treatments (median follow-up after salvage: 13.1 months), 43.8% (7 of 16) of whom underwent salvage surgery alone for a 2-year overall salvage radiation need of 4.5% (9 of 200). The 2-year outcomes for the 59 evaluable patients among the 109 AJCC 7th pT0-2 N2a-N2b patients with 1 to 3 pathologic lymph nodes (LNs) were as follows: local recurrence, 3.4% (2 of 59); regional recurrence, 8.4% (5 of 59); distant metastases, 0%; DFS, 88.1% (52 of 59); DSS, 100% (59 of 59); OS, 96.7% (59 of 61); and salvage radiation, 5.1% (3 of 59). CONCLUSIONS With careful selection, surgery alone for AJCC 7th pT0-T2N0-N2b HPV+OPSCC with zero to 3 pathologic LNs without perineural invasion, extranodal extension, or positive margins results in high DFS, DSS, OS, and salvage treatment success. Because of the short-term follow-up, these data support further investigation of treatment de-escalation in this population.

Transoral robotic surgery versus nonrobotic resection of oropharyngeal squamous cell carcinoma. Head Neck 2021; 43:2259-2273. [PMID: 33899949 DOI: 10.1002/hed.26724] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Revised: 03/07/2021] [Accepted: 04/14/2021] [Indexed: 12/30/2022] Open
Abstract
The aim of this study is to evaluate the impact of transoral robotic surgery (TORS) compared to nonrobotic surgery (NRS) on overall survival in oropharyngeal squamous cell carcinoma (OPSCC). We performed a retrospective study of patients with HPV+ and HPV- OPSCC undergoing TORS or NRS with neck dissection using the National Cancer Database from the years 2010-2016. Among patients with OPSCC in our cohort, 3167 (58.1%) patients underwent NRS and 2288 (41.9%) underwent TORS. TORS patients demonstrated better overall survival than NRS patients (HPV+ patients: aHR 0.74, p = 0.02; HPV- patients: aHR 0.58, p < 0.01). Subsite analysis showed TORS was correlated with improved survival in base of tongue (BoT) primaries for both HPV+ (aHR 0.46, p = 0.01) and HPV- (aHR 0.42, p = 0.01) OPSCC. Compared to NRS, TORS is associated with improved overall survival for HPV+ and HPV- OPSCC, as well as greater overall survival for BoT primaries.

Abstract
OBJECTIVE The purpose of this study was to analyze the relationship between body mass index (BMI) and 30-day morbidity and mortality risk in patients undergoing tracheostomy using the American College of Surgeons National Quality Improvement Program (ACS-NSQIP). STUDY DESIGN This is a retrospective, cross-sectional, cohort study. SETTING Patients were identified with Current Procedural Terminology codes in the ACS-NSQIP database. SUBJECTS AND METHODS Patients who underwent tracheostomy from 2005 to 2018 were queried. They were stratified into four BMI classes and matched to normal BMI cohorts. Multivariate logistic regression was used to identify independent predictors for complications, readmissions, and unplanned reoperations within 30 days. RESULTS Among 3784 patients meeting inclusion and exclusion criteria, obesity was shown to be a significant independent risk factor for overall complications (OR 1.439, 95% CI 1.226-1.689, p < 0.001), postoperative acute renal failure (OR 10.715, 95% CI 1.213-94.646, p = 0.033), and unplanned readmissions (OR 1.702, 95% CI 1.095-2.647, p = 0.018). A significantly lower rate of postoperative transfusions was observed for obese patients (OR 0.581, 95% CI 0.432-0.781, p < 0.001). CONCLUSIONS Obesity was found to be independently associated with an increased risk of overall complication, developing acute renal failure, and having an unplanned 30-day readmission following tracheostomy. The risk of postoperative transfusion appears to be lower in obese patients. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVE There is increasing literature supporting the use of extracapsular dissection (ECD) for the treatment of select superficial lobe parotid tumors, though no objective criteria for selection has been proposed. Prior studies have suggested the minimum distance between the parotideomasseteric fascia and the tumor edge or minimum fascia-tumor distance (MFTD) as a useful measurement for the identification of superficial parotid tumors. The objective of this study is to demonstrate the utility of the minimum fascia-tumor distance in selecting candidates for extracapsular dissection of benign parotid tumors. METHODS This is a retrospective case-control study at a tertiary academic otolaryngology clinic. Twenty-three patients with prior surgical excision of benign parotid tumors that underwent surgeon-performed ultrasonography prior to excision of tumor were identified. Ultrasound images were reviewed and the minimum fascia-tumor distance was recorded and categorized by less than 3 mm or as 3 mm or greater. The primary outcome was successful completion of extracapsular dissection versus more extensive resection. RESULTS Thirteen patients had a minimum fascia-tumor distance less than 3 mm; eleven of thirteen (84.6%) successfully underwent extracapsular dissection. Ten patients had a minimum fascia-tumor distance of 3 mm or greater; one of ten (10%) successfully underwent extracapsular dissection. A minimum fascia-tumor distance less than 3 mm was sensitive, specific, and accurate in predicting successful ECD at 91.7%, 81.8%, and 87.0% respectively (OR 49.5, 95% CI 3.4-573.2). CONCLUSION Minimum fascia-tumor distance may be a useful measurement in identifying candidates for removal of benign parotid tumors with extracapsular dissection.

Abstract
BACKGROUND Although complication rates after thyroidectomy are well described in the literature, the timing of these events is less understood. This study delineates the timeline and risk factors for early adverse events after thyroidectomy. MATERIALS AND METHODS This study included a retrospective review of 161,534 patients who underwent thyroidectomy between 2005 and 2018 using the American College of Surgeons National Surgical Quality Improvement Program database. Time to specific complications was analyzed for all patients undergoing thyroidectomy, with further stratification of hemithyroidectomy and total thyroidectomy cohorts. Univariate analyses were conducted to analyze demographics, preoperative comorbidities, and complications. A multivariate logistic regression model was generated to identify significant risk factors for 7-day postoperative complications. RESULTS The overall complication rate was 3.28%. A majority of complications arose before discharge including the following: blood transfusion (96%), hematoma formation (68%), pneumonia (53%), and cardiac arrest (67%). Approximately 37% of unplanned reoperations occurred before discharge in the hemithyroidectomy versus 63% in the total thyroidectomy cohort. Greater than 65% of mortalities occurred after discharge in both groups. Complications generally occurring within 7 d for the entire cohort included the following: pneumonia (3; 2-8 [median postoperative day; interquartile range]), pulmonary embolism (6; 2-12), cardiac arrest (1; 0-5), myocardial infarction (2; 1-6), blood transfusions (0; 0-1), and hematoma formation (0; 0-2). Superficial surgical site infection (9; 6-16) occurred later. Patients who underwent outpatient surgery had a decreased risk of complications (odds ratio 0.41) in the 7-day postoperative period. CONCLUSIONS Although early complications after thyroidectomy are rare, they have a distinct time course, many of which occur after discharge. However, in selected patients undergoing outpatient thyroidectomy, overall risk of complications is decreased. Understanding timing helps establish better preoperative communication and education to improve postoperative expectations for the provider and patient.

Abstract
OBJECTIVES/HYPOTHESIS The aim of the study was to introduce and study the role of standardized views for ultrasound of the major salivary glands in resident learning and retention. STUDY DESIGN Methods description and prospective case series. METHODS Five otolaryngology residents and two patient models were recruited for this study. The participants were timed on their identification of the submandibular gland, sublingual gland, and parotid gland and associated key anatomic structures. Participants were then timed again immediately after being presented a standardized view for each salivary gland: the longitudinal submandibular gland, transverse parotid gland, and submental transverse views. The same participants were then timed one month later to determine retention. A Wilcoxon signed-rank test was used to evaluate whether time to identification was equal pre- and post-standardized view instruction. RESULTS There was a significant improvement from pre- to post-standardized view instruction in all glands, which was sustained one month later. Practically speaking, assessment times for all participants at the one-month measurement were reasonable, with averages of 71, 42, and 114 s for the submandibular gland, sublingual gland, and parotid gland respectively. CONCLUSIONS Standardized views provided otolaryngology ultrasonography learners with a reliable, fast, and memorable way to assess the salivary glands and their related structures.

Abstract
The Coronavirus Disease-2019 (COVID-19) pandemic has created an unprecedented economic and public health crisis in the United States. Following efforts to mitigate disease spread, with a significant decline in some regions, many states began reopening their economies. As social distancing guidelines were relaxed and businesses opened, local outbreaks of COVID-19 continue to place person on healthcare systems. Among medical specialties, otolaryngologists and their staff are among the highest at risk for becoming exposed to COVID-19. As otolaryngologists prepare to weather the storm of impending local surges in COVID-19 infections there are several practical measures that can be taken to mitigate the risk to ourselves and our staff.

Abstract
A 74-year-old man was referred to a tertiary academic otolaryngology clinic for evaluation of a left-sided neck mass with unknown primary. Nuclear imaging modalities revealed a primary cancer located at the left tongue base. Further investigation revealed the tumour to be a p16 positive squamous cell cancer with metastatic spread to cervical lymph nodes of multiple levels. The patient was found on initial investigation to have microstomia and a retrognathic mandible, which are typically considered unsuitable for robotic surgery due to difficulties obtaining adequate exposure.The patient underwent bilateral neck dissection, followed by transoral robotic-assisted left base of tongue resection. A midline intraoral mandibulotomy was performed to improve robotic access. Following tumour resection, the mandible was repaired using open reduction with internal plate fixation. Postoperative occlusion was maintained, and the patient recovered well from mandibulotomy with none of the morbidity or cosmetic defects associated with a traditional lip-split approach.

Abstract
BACKGROUND Implantable Dopplers (IDs) are widely used for postoperative free flap vascular monitoring. However, IDs may contribute to free flap complications or failure and better understanding of device malfunctions is needed. METHODS The U.S. Food and Drug Administration's Manufacturer and User Facility Device Experience database was queried for all reports of ID adverse events from two leading manufacturers (Cook Vascular and Synovis Life Technologies) in free flap surgery from January 2010 to March 2020. Reports were reviewed and categorized. A comparison of reoperations within select categories was performed using Chi-square analysis. RESULTS Of 209 included reports, the most common device malfunctions were venous anastomotic coupler misalignment (35.4%) and coupler ring detachment (24.4%). Synovis devices were used in 100% of reports of vessel compression and Cook Vascular devices were used in 77.7% of reports of probe detachment. Of 74 patient-related adverse events, the most common were reoperation (47.3%) and vessel occlusion (28.4%). Of five reported events of flap failure, two were associated with loss of ID signal. The proportion of Doppler signal loss events leading to reoperation was significantly greater than the proportion of any other Doppler-related event leading to reoperation. Intraoperative coupler replacement was the most commonly reported intervention (n = 86), and venous anastomosis with hand-suturing occurred in 30 device malfunctions. CONCLUSION This study demonstrates a variety of ID-related malfunctions. One-third of device malfunctions were associated with patient complications, and false-positive Doppler signal loss contributed substantially to the requirement of surgical re-exploration. These are important considerations for surgical teams utilizing IDs in free tissue transfer procedures.

Abstract
OBJECTIVE To evaluate surgical approaches and outcomes associated with accessory parotid gland neoplasms. DATA SOURCES MEDLINE, SCOPUS, and the Cochrane Central Register of Controlled Trials. REVIEW METHODS A systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was performed. Studies were included if they reported surgical management and outcomes of patients with accessory parotid gland neoplasms. RESULTS After screening 3532 records, 15 studies were included with a total of 187 patients. Benign tumors consisted of 61.5% of cases. External open, transoral, and preauricular endoscopic approaches were used for 82.3%, 11.3%, and 6.5% of cases, respectively. Accessory lobe resection alone, concurrent with partial parotidectomy, and concurrent with total parotidectomy were used in 54.8%, 43.0%, and 2.2% of cases, respectively. Complication rates were similar between histology groups (7.8% benign vs. 8.3% malignant, p = 0.82). Accessory lobe resection with concurrent partial parotidectomy had the lowest overall complication rate (6.3%). Resections limited to the accessory lobe were found to have an overall complication rate of 8.7%. CONCLUSION The results offer an overview of the surgical management and complications for accessory parotid gland tumors. Overall surgical complication rates found in these case series may be lower for management of accessory gland tumors than rates available in the literature for tumors within the main parotid gland.

Abstract
OBJECTIVES Recent literature suggests that outpatient head and neck surgery is safe and may decrease costs. This study assesses whether outpatient parotidectomy differs in complication type and rate from inpatient surgery. METHODS Patients who underwent parotidectomy at our institution from 2011 to 2019 were retrospectively reviewed and divided by inpatient or outpatient status. Complications including infection, seroma, salivary fistula, hematoma, and flap necrosis, as well as readmission rates were tabulated. Drain placement, related to tumor size, was also analyzed using a receiver operating curve. RESULTS 144 patients had available data for analysis. Nine of the 144 patients had complications. Seven of 98 outpatients and two of 46 inpatients had complications. There was no statistically significant difference in complication rate between the two groups (P = .518). Tumor size ≥4.62 cm3 was associated with drain placement (P = .044). CONCLUSION Outpatient parotidectomy is a safe and viable alternative for carefully selected patients.

Abstract
OBJECTIVES The present study was developed to evaluate the accuracy of in vivo ultrasound sizing for parotid and submandibular salivary gland calculi, as compared with ex vivo pathology sizing with a standard plastic ruler after extraction. STUDY DESIGN Retrospective chart review. SETTING Ultrasound is frequently used to size salivary calculi and make treatment decisions, but the accuracy of measurements from this modality has not been validated. SUBJECTS AND METHODS We evaluated and reviewed the charts and ultrasound examinations of 167 patients who underwent procedures for the treatment of sialolithiasis involving the parotid and submandibular glands. US examinations were performed between 2009 and 2016 in a tertiary-level hospital setting by the senior author. Measurements were collected from ultrasound evaluation before sialolithotomy, and pathology measurements were taken after removal. Ultrasound measurements in millimeters were compared with the measurements collected with a ruler. The differences were calculated and compared. RESULTS A total of 167 calculi measurements were compared. Good concurrent validity between pathology and ultrasound measurements was suggested by a Pearson correlation of 0.92 (95% CI, 0.887-0.937). On Bland-Altman plot, correlation of the difference between US and pathology measurements showed a mean difference of 0.095 mm (95% CI, -0.19 to 0.38 mm) with a limit of agreement ranging from -3.59 mm (95% CI, -3.84 to -3.34 mm) to +3.78 mm (95% CI, +3.53 to +4.03 mm). CONCLUSIONS Ultrasound is an accurate, relatively precise, and minimally invasive imaging tool for salivary gland sialolithiasis. Preoperative size of calculi can be used to guide management and clinical decision making. LEVEL OF EVIDENCE 2C.

Abstract
A 60-year-old woman was referred to the otolaryngologist for 18 months of left-sided tongue pain and taste changes. Surgeon-performed ultrasound of the submandibular region revealed a hyperechoic mass. Wharton's duct was dilated proximally and the submandibular gland demonstrated normal vascularity. While these findings were highly suspicious for submandibular gland sialolith, an in-office attempt at sialolithotomy suggested an alternate process or mass. After imaging failed to further elucidate an aetiology, surgical exploration revealed a well-circumscribed submandibular mass associated with the lingual nerve. The mass was removed en-bloc and pathology revealed a schwannoma of the lingual nerve.

Abstract
BACKGROUND Synovial osteochondromatosis is a rare but benign condition that can result in significant impairment of joint functionality. This case report documents an uncommon presentation of this disorder occurring within the temporomandibular joint, causing the patient significant pain, trismus, and difficulty with daily activities such as eating and speaking. A review of the literature including disease mechanisms and previously documented cases is included to provide comprehensive background for clinical decision-making.
CASE SUMMARY A 48-year-old male patient presented with a 3-mo history of trismus, crepitus with jaw movement and significant pain while chewing. Physical examination revealed a firm mass and tenderness to palpation at the right temporomandibular joint. Further workup revealed a bilobed mass extending into the joint space as well as significant bony erosion of the glenoid fossa. The patient underwent mass excision with joint reconstruction and pathology revealed synovial osteochondromatosis. The patient reported significant improvement in his symptoms postoperatively.
CONCLUSION This report outlines the investigative approach and treatment course of synovial osteochondromatosis. The positive outcome following surgical intervention in this case emphasizes the importance of interdisciplinary collaboration and the potential for improvement in quality of life of this patient population.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common cancer in the head and neck region, and is associated with high morbidity and mortality rates. Surgical resection is usually the primary treatment strategy for OSCC, and maintaining effective tumor resection margins is paramount to surgical outcomes. In practice, wide tumor excisions impair post-surgical organ function, while narrow resection margins are associated with tumor recurrence. Identification and tracking of these resection margins remain a challenge because they migrate and shrink from preoperative chemo or radiation therapies, and deform intra-operatively. This paper reports a novel near-infrared (NIR) fluorescent marking and landmark-based deformable image registration (DIR) method to precisely predict deformed margins. The accuracy of DIR predicted resection margins on porcine cadaver tongues is compared with rigid image registration and surgeon's manual prediction. Furthermore, our tracking and registration technique is integrated into a robotic system, and tested using ex vivo porcine cadaver tongues to demonstrate the feasibility of supervised autonomous tumor bed resections.

Abstract
This paper specifies a surgical robot performing semi-autonomous electrosurgery for tumor resection and evaluates its accuracy using a visual servoing paradigm. We describe the design and integration of a novel, multi-degree of freedom electrosurgical tool for the smart tissue autonomous robot (STAR). Standardized line tests are executed to determine ideal cut parameters in three different types of porcine tissue. STAR is then programmed with the ideal cut setting for porcine tissue and compared against expert surgeons using open and laparoscopic techniques in a line cutting task. We conclude with a proof of concept demonstration using STAR to semi-autonomously resect pseudo-tumors in porcine tissue using visual servoing. When tasked to excise tumors with a consistent 4mm margin, STAR can semi-autonomously dissect tissue with an average margin of 3.67 mm and a standard deviation of 0.89mm.

Interferometric focal length measurement of positive and negative lenses using a lateral-shearing cyclic path optical configuration setup and polarization phase-shifting interferometry. APPLIED OPTICS 2017; 56:8414-8419. [PMID: 29091620 DOI: 10.1364/ao.56.008414] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2017] [Accepted: 09/26/2017] [Indexed: 06/07/2023]
Abstract
We present a simple interferometric focal length measurement technique for measuring the focal length of positive and negative lenses using a lateral-shearing cyclic path optical configuration (CPOC) setup and polarization phase-shifting interferometry (PPSI). The technique requires an auxiliary lens, whose focal length need not be known accurately, for generating a focused point source at its focal plane. The focal point of the test lens is adjusted to be in the vicinity of the focus of the auxiliary lens. The radii of the resulting spherical wave fronts emerging from the test lens, due to the defocus, for two different longitudinal shifted positions of the test lens are measured using the lateral-shearing CPOC setup and PPSI. Focal length of the test lens is determined from the known longitudinal shift and from the measured radii of the spherical wave fronts. Results obtained for 200.0 mm convex and 100.0 mm concave test lenses are presented.

Minimally elevated preoperative parathyroid hormone level influences the management of primary hyperparathyroidism. Laryngoscope 2017; 128:1016-1021. [PMID: 28850730 DOI: 10.1002/lary.26699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2016] [Revised: 03/05/2017] [Accepted: 04/25/2017] [Indexed: 11/11/2022]
Abstract
OBJECTIVES/HYPOTHESIS To determine the effect of preoperative parathyroid hormone (PTH) level on the extent of surgery and the accuracy of parathyroid imaging in primary hyperparathyroidism. STUDY DESIGN Retrospective cohort. METHODS Final diagnosis of single-gland adenoma and its location versus multigland disease was established in this retrospective cohort study. Positive predictive value, negative predictive value, and accuracy of imaging were analyzed in relation to preoperative PTH levels. RESULTS Eighty-seven percent of the 218 patients enrolled in the study underwent unilateral targeted operation and had a 97.9% (95% confidence interval: 95.8%-100%) success rate. However, in patients with PTH <65 pg/mL, 28.6% had bilateral exploration compared to 10.3% in those with PTH ≥65 pg/mL (P = .042). In patients with PTH <65 pg/mL, 7/21 (33.3%) had inaccurate sestamibi findings compared to 24/174 (13.8%) in patients with PTH ≥65 pg/mL (P = .047). CONCLUSIONS Accuracy of sestamibi drops significantly, by threefold, in patients with mild primary hyperparathyroidism and PTH <65 pg/mL. Patients with PTH < 65 pg/mL have a 2.5-fold higher rate of bilateral operation to identify the hypersecreting gland(s) compared to patients with PTH ≥65 pg/mL. LEVEL OF EVIDENCE 4.

Importance of FNA Technique for Decreasing Non-diagnostic Rates in Thyroid Nodules. Head Neck Pathol 2017; 12:160-165. [PMID: 28819755 PMCID: PMC5953868 DOI: 10.1007/s12105-017-0844-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2017] [Accepted: 07/31/2017] [Indexed: 01/26/2023]
Abstract
To identify potential interventions that may lower the high non-diagnostic rates associated with ultrasound guided (US) fine needle aspiration (FNA) biopsy of the thyroid nodule. A case series of 164 thyroid nodule US-guided FNA was identified retrospectively. The following variables were analyzed in regards to diagnostic and non-diagnostic sampling: patient age, gender, size of nodule, biopsy technique (capillary vs. aspiration), needle gauge (23 vs. 25), and physician experience. The FNA diagnosis, and final pathology, when applicable, was recorded for each sample using the Bethesda criteria. Data was analyzed using the Fisher's exact test or the chi square test. After multivariate logistic regression, capillary action was independently associated with lower non-diagnostic rates (p = 0.01), while increasing patient age was associated with higher non-diagnostic rates (p = 0.018). Physician experience (p = 0.014) was not independently associated with lower non-diagnostic rates. Nodules that were "cystic >50%" were significantly more likely to yield a non-diagnostic result (p < 0.0001). After taking into account confounding variables, including physician experience, our data reveals a statistically significant decrease in non-diagnostic rates with the use of capillary action vs. aspiration technique in US-guided FNA. A major focus in healthcare today is providing cost-effective and minimally invasive care to the patient. In the setting of a rising incidence of thyroid disease, we believe our study demonstrates the need for a prospective analysis of the relationship between technique and non-diagnostic rates.

Abstract
The submental island flap was first described as a tool for facial reconstruction after tumor resection. It is now widely used for reconstructing numerous structures in the head and neck region of adults. Pediatric surgical reconstruction is a challenging task that continues to evolve over time. We describe two novel uses of this flap in the pediatric population. The submental island flap is an excellent option for reconstruction in pediatrics given its ease of elevation, excellent cosmetic outcomes, and low donor site morbidity.

Volumetric Facelift: Evaluation of Rhytidectomy with Alloplastic Augmentation. Ann Otol Rhinol Laryngol 2017; 119:174-80.

Abstract
Objectives Facial aging occurs as a result of soft tissue atrophy and resorption of the bony skeleton, which results in a loss of soft tissue volume and laxity of the overlying skin. Volumetric augmentation is a key component of facial rejuvenation surgery, and should be considered of equal importance to soft tissue lifting. Augmentation can be accomplished with synthetic fillers, autologous grafts, soft tissue repositioning techniques, and/or alloplastic implants. Only alloplastic implants, however, provide truly long-term volumetric correction. To date, there have been no large series dealing with the complications and results of implantation performed concurrently with rhytidectomy, which we have termed “volumetric rhytidectomy.” We present our experience with 100 patients treated with a combination of malar and chin implants and rhytidectomy, compared to 200 patients who underwent rhytidectomy alone. Methods The authors performed a retrospective review of patients treated with a combination of silicone malar and chin augmentation with rhytidectomy versus patients treated with rhytidectomy alone. Both groups of patients underwent close postoperative evaluation at 3 days, 1 week, 2 weeks, and 1 month. All patients were surveyed at 6 months to assess aesthetic satisfaction. Complication rates were noted and tabulated. Statistical analysis was performed to evaluate for any differences in the two groups. Results Between 2002 and 2006, 100 patients underwent malar and chin implantation along with rhytidectomy; 200 patients underwent rhytidectomy alone. In the first group, there were a total of 6 cases in which implant removal was necessary, and 2 cases in which revision was required. There were no statistically significant differences (p < 0.05) observed between the two groups with respect to major or minor hematoma, seroma, infection, sensory nerve injury, facial nerve injury, hypertrophic scarring, dehiscence, skin sloughing, or revision. Conclusions Volumetric rhytidectomy reliably augments the malar and mental areas, allows for subtle skeletal contouring, and results in successful rejuvenation. Rhytidectomy is relatively safe to perform concurrently with silicone augmentation, and does not result in an increased complication rate as compared to rhytidectomy alone.

Abstract
Transcranial masses in the infant population can leave considerable skull base defects following resection. Traditional reconstructive techniques can result in significant morbidity or poor cosmetic results. We present a case of a large skull base defect in a six week-old infant, after removal of a giant cranio-cervicofacial teratoma, which was reconstructed using a versatile submental island flap. Additionally, preoperative planning and intraoperative navigation was advanced with the use of a 3D constructed model of the patient's mass.

Abstract
PURPOSE It has been long known that sialendoscopy has both diagnostic and therapeutic benefits in the identification and treatment of sialadenitis. Sialendoscopy can also be used to triage patients with traumatic injury or foreign bodies lodged in the parotid gland. PROCEDURES We present a case of traumatic insertion a fishbone into the parotid gland parenchyma that was evaluated with sialendoscopy and successfully managed on the basis of stable endoscopy findings that correlated with improving symptomatology. MAIN FINDINGS We find that sialendoscopy presents a useful tool to help guide management. CONCLUSIONS We demonstrate that in an asymptomatic patient, foreign body impaction with absence of ductal obstruction on endoscopy can successfully be followed with simple observation.

Abstract
OBJECTIVE: To characterize gene expression in sinonasal polyps and to gain insight into change in expression after oral corticosteroid treatment. STUDY DESIGN AND METHODS: Nasal polyps were obtained before and after oral corticosteroid treatment and gene expression was analyzed with a focused gene array technique. RESULTS: Pretreated sinonasal polyps demonstrated high gene expression for chemokine and leukotriene receptor genes (CCR2, CCR5, CX3CL1, and LTB4R) in all patients. After treatment, the global effects of corticosteroids were evident on gene expression. CONCLUSIONS: Gene array techniques hold promise as a research method in sinonasal polyposis. The potential benefits, as well as the potential challenges, in using these research methods will be discussed.
