A Reproducible Peritonsillar Abscess Incision and Drainage Model for Junior Trainees.

OBJECTIVES: To describe the design and construction of a reproducible, low-cost, peritonsillar abscess (PTA) incision and drainage simulator and assess its impact on trainees' confidence. METHODS: The 2-part simulator we developed consisted of a manikin head with a fixed, partially open mouth and a modular PTA mold. The mold is created by injecting a lotion and water mixture into plastic bubbles, followed by silicone solidification. Neodymium magnets secure the silicone-abscess packet to the manikin's palate. The simulator was utilized during an academic otolaryngology residency training program Annual Otolaryngology Boot Camp. A self-assessment Likert scale questionnaire was used to evaluate participants' confidence before and after simulator training. Fourth-year medical students and junior (first and second year) residents who participated in the boot camp and agreed to complete the evaluation were included. RESULTS: Three medical students, 17 PGY-1, and 10 PGY-2 residents agreed to complete the evaluation. All trainees agreed the model was useful for learning skills. The overall post-training confidence Likert scores of participants, and PGY-1 residents in particular, significantly improved compared to their pre-training scores (P < .001). CONCLUSIONS: Our model offers an affordable and efficient training opportunity for residents to enhance their competence in managing PTAs. This approach, with its simple yet effective design and low production cost, shows potential for scalability on a broader scale.

Development of hypothyroidism following hemithyroidectomy: A population-based study.

PURPOSE: Hypothyroidism is a known possibility after hemithyroidectomy, with a highly variable incidence in the literature ranging from 8 to 60 %. Incidence of hypothyroidism after hemithyroidectomy was evaluated with a secondary aim to assess incidence in patients with Hashimoto's disease. MATERIALS & METHODS: A retrospective study using the TriNetX global federated research network was performed. We included patients within the last 15 years that were ≥18 years of age and had Current Procedural Terminology codes for hemithyroidectomy. Patients were excluded if they had a total or completion thyroidectomy at any time, a history of thyroid cancer, were preoperatively either on levothyroxine, diagnosed with hypothyroidism, or had a Thyroid Stimulating Hormone ≥ 4 m[IU]/L. We assessed the 3 month incidence of hypothyroidism postoperatively based on the International Classification of Diseases code, TSH ≥ 4 m[IU]/L, or taking levothyroxine after surgery. RESULTS: 6845 patients met the inclusion criteria. Most of the cohort was female (67 %) and white (63 %). The mean age at surgery for this population was 54 ± 14.8 years. During the 15 years of data, we found the 3-month incidence of hypothyroidism following hemithyroidectomy to be 23.58 %. The median time to develop the disease was 41.8 months. A subgroup analysis of those with Hashimoto's revealed a 3-month incidence of 31.1 % of patients developing hypothyroidism after surgery. CONCLUSIONS: This population-based study gives additional insight into the incidence of hypothyroidism after hemithyroidectomy. This will help improve perioperative patient counseling and management.

Bell's Palsy and COVID-19: Insights from a Population-Based Analysis.

Background: Coronavirus disease 2019 (COVID-19) has been linked to Bell's palsy and facial paralysis. Studies have also shown increased risk of Bell's palsy in unvaccinated COVID-19 patients. Objective: To compare the relationship between Bell's palsy and COVID-19 infection and vaccination. Design: This is a retrospective longitudinal study. Methods: The COVID-19 research network was used to identify patients with facial palsy presenting to 70 health care organizations in the United States. The incidence of Bell's palsy was measured within an 8-week window after COVID-19 test or vaccination event in identified patients. Results: Incidence of facial palsy diagnosis (0.99%) was higher than the background rate within 2 months of COVID-19 infection. When compared with their negative counterparts, patients with COVID-19 infection had significantly higher risk of Bell's palsy (risk ratio [RR] = 1.77, p < 0.01) and facial weakness (RR = 2.28, p < 0.01). Risk ratio was also amplified when evaluating Bell's palsy (RR = 12.57, p < 0.01) and facial palsy (RR = 44.43; p < 0.01) in COVID-19-infected patients against patients who received COVID-19 vaccination. Conclusion: In our patient population, there is a higher risk of developing facial palsy within 2 months of COVID-19 infection versus vaccination. Vaccinated patients are not at higher risk of developing facial palsy.

A Systematic Review of Peritonsillar Abscess Simulators: Enhancing Training and Identifying the Need for Standardization.

OBJECTIVES: To systematically review the literature regarding previously described peritonsillar abscess (PTA) drainage simulation. DATA SOURCES: PubMed, Scopus, Web of Science, Ovid, and Cochrane. REVIEW METHODS: A search of the abovementioned databases was performed in August 2022 using the terms "peritonsillar abscess/quinsy," "incision/drainage/aspiration," and "simulation." No time restrictions were applied. We included studies that clearly described how their PTA models were built and underwent validation from experts and/or evaluation from trainees. Articles describing a model only without any evaluation and reports in languages other than English were excluded. RESULTS: Our search initially yielded 80 articles after duplicate removal, 10 of which met our criteria and were included. Two studies trained participants on both needle aspiration and incision and drainage (I&D), four studies on I&D only, and four on needle aspiration only. 87.5% to 100% of junior residents reported minimal exposure to PTA prior to simulation. Five studies provided some form of validation to their models. The value of the simulators to train participants on skills received better appreciation than their anatomical fidelity. The perceived confidence level of trainees in managing PTA, which was assessed in 7 studies, substantially improved after training. CONCLUSION: PTA simulation improves the confidence of trainees to perform PTA drainage. There is, however, a lack of standardization and evidence regarding transfer validity among PTA simulators. The development of a standardized PTA simulator could allow for more widespread use and increase resident comfort with this procedure in a pre-clinical setting.

Free Flap Outcomes for Head and Neck Surgery in Patients with COVID-19.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) affects the vascular system, subjecting patients to a hypercoagulable state. This is of particular concern for the success of microvascular free flap reconstruction. This study aims to report head and neck free flap complications in patients with COVID-19 during the perioperative period. We believe these patients are more likely to experience flap complications given the hypercoagulable state. METHODS: This is a multi-institutional retrospective case series of patients infected with COVID-19 during the perioperative period for head and neck free flap reconstruction from March 2020 to January 2022. RESULTS: Data was collected on 40 patients from 14 institutions. Twenty-one patients (52.5%) had a positive COVID-19 test within 10 days before surgery and 7 days after surgery. The remaining patients had a positive test earlier than 10 days before surgery. A positive test caused a delay in surgery for 16 patients (40.0%) with an average delay of 44.7 days (9-198 days). Two free flap complications (5.0%) occurred with no free flap deaths. Four patients (10.0%) had surgical complications and 10 patients had medical complications (25.0%). Five patients (12.5%) suffered from postoperative COVID-19 pneumonia. Three deaths were COVID-19-related and one from cancer recurrence during the study period. CONCLUSION: Despite the heightened risk of coagulopathy in COVID-19 patients, head and neck free flap reconstructions in patients with COVID-19 are not at higher risk for free flap complications. However, these patients are at increased risk of medical complications. LEVEL OF EVIDENCE: 4 Laryngoscope, 2023.

Examining the relationship between COVID-19 and Bell's palsy: Experience of a single tertiary care center.

BACKGROUND: While the etiology of Bell's palsy (BP) is largely unknown, current evidence shows it may occur secondary to the immune response following a viral infection. Recently, BP has been reported as a clinical manifestation of coronavirus disease (COVID-19). OBJECTIVES: To investigate an association between COVID-19 infection and BP. Additionally, to evaluate the need for COVID-19 testing in patients who present with BP. METHODS: Hospital records of patients who presented to a single tertiary care center with BP in 2020 and 2021 were reviewed for presenting symptoms, demographics, COVID-19 infection and vaccination status. RESULTS: There was no statistically significant difference between patients with BP who had a positive or negative COVID test in terms of sex, BMI, age, race, smoking history or alcohol use. All 7 patients with BP and a positive COVID test were unvaccinated. Of the total cohort of 94 patients, 82 % were unvaccinated at the time of the study. None of the 17 patients who were vaccinated had a positive COVID test. A history of BP showed no statistical significance (10.3 % vs 14.3 %, p-value 0.73). CONCLUSION: We discovered a limited cohort of patients who underwent COVID-19 testing at the time of presentation for BP. Though there have been recent studies suggesting a COVID-19 and BP, we were unable to clearly identify a relationship between COVID-19 and BP. Interestingly, all patients with facial paralysis and COVID-19 were unvaccinated. To further study this relationship, we recommend consideration of a COVID-19 test for any patient that presents with facial paralysis.

Prognostic significance of time trends in treatment of head and neck squamous cell carcinoma.

PURPOSE: To analyze the impact of demographic, clinical, and management variables on time to treatment initiation (TTI) and overall survival (OS). STUDY DESIGN: Retrospective chart review. MATERIALS AND METHODS: Medical records of patients diagnosed with head and neck cancer from 2018 to 2020 were reviewed. Univariate linear and Cox-regressions identified predictors of TTI and OS. Kaplan Meier (KM) curves assessed the difference in survival by diagnostic year and TTI. RESULTS: 381 patients met eligibility criteria. Median TTI was 35.0 days (IQR: 25.0-49.0). Only 10.8 % of all patients reported any treatment delay, with TTI exceeding 90 days found in 3.7 % of patients. TTI increased with African American race (p = 0.02), ED referrals (p = 0.02), and direct admission status (p = 0.01). When compared to treatment with surgery alone, TTI was shorter in patients undergoing surgery with adjuvant radiation (p = 0.02), adjuvant chemoradiation (p = 0.04), and salvage surgery (p = 0.04). Univariate Cox-regressions found smoking (p = 0.01), direct admission status (p = 0.02), increased duration of symptoms (p = 0.02), placement of PEG tubes (p < 0.01) and tracheostomies (p < 0.01), combination treatment (p < 0.01), and surgery with adjuvant chemoradiation treatment (p = 0.01) to increase mortality risk. Disease characteristics, including tumor size (p < 0.01), presence of nodal disease (p = 0.02), and late-stage disease (p < 0.01), increased mortality risk. TTI and diagnostic year did not impact survival. CONCLUSIONS: Our analysis determined several demographic, referral, and treatment factors impacted TTI. However, increased TTI did not impact survival. Characteristics consistent with advanced disease worsened OS. Despite the pandemic burden, patients diagnosed in 2020 showed no difference in short-term survival compared to prior years.

Clinical outcomes following intraoperative pedicle disruption in fibula free flaps.

OBJECTIVES: Iatrogenic injury of the fibula free flap pedicle is rare. Postoperative flap survival and reconstructive outcomes following intraoperative pedicle severance are unknown. This study assesses free flap outcomes following accidental severance of the peroneal vessels. METHODS: Multi-institutional retrospective chart review from 2000 to 2020. RESULTS: Of 2975 harvested fibula free flaps, 26 had a history of pedicle severance during surgical reconstruction. Reasons for intraoperative pedicle severance included transection during muscular dissection 10/26 (39%), accidental severance with the bone saw 12/26 (46%), and other 4/26 (15.6%). The surgeon responsible for pedicle severance included residents 5/26 (19%), fellows 10/26 (39%), attendings 10/26 (39%), and unknown 1/26 (3.9%). The pedicle artery and vein were severed 10/26 (39%), artery 8/26 (31%), and vein 8/26 (31%). Truncated pedicle vessels were used 3/26 (11.7%), intraoperative anastomoses were performed 23/26 (89%). Postoperative revision in the OR within 7 days of surgery was required 6/26 (23%); 4 flaps were salvaged and 2 flaps failed, both arterial thrombosis. Flap failure was attributed to vascular thrombosis. Long-term flap survival and successful reconstructions were reported 24/26 (92%). CONCLUSION: Accidental severance of fibula free flap pedicle vessels can be corrected with intraoperative repair, without affecting long-term flap survival or reconstructive outcomes. Protecting the flap vessels while using the bone saw and during intramuscular dissection prevents accidental severance.

Free Flap Donor Sites in Head and Neck Reconstruction.

Microvascular free tissue transfer, also referred to as free flaps surgery, is a reconstructive technique that has become a foundational component of complex head and neck reconstruction. There have been considerable advancements in the field over the last 30 years including the number and variety of free flaps. Each of these free flaps has unique characteristics that must be considered for the defect when selecting a donor site. Here, the authors focus on the most common free flaps used in head and neck reconstruction.

Loss to Follow-up in Head and Neck Cancer: A Systematic Review of Randomized Controlled Trials.

OBJECTIVE: To evaluate the reporting and rates of loss to follow-up (LTFU) in head and neck cancer (HNC) randomized controlled trials based in the United States. DATA SOURCES: Pubmed/MEDLINE, Cochrane, Scopus databases. REVIEW METHODS: A systematic review of titles in Pubmed/MEDLINE, Scopus, and Cochrane Library was performed. Inclusion criteria were US-based randomized controlled trials focused on the diagnosis, treatment, or prevention of HNC. Retrospective analyses and pilot studies were excluded. The mean age, patients randomized, publication details, trial sites, funding, and LTFU data were recorded. Reporting of participants through each stage of the trial was documented. Binary logistic regression was performed to evaluate associations between study characteristics and reporting LTFU. RESULTS: A total of 3255 titles were reviewed. Of these, 128 studies met the inclusion criteria for analysis. A total of 22,016 patients were randomized. The mean age of participants was 58.6 years. Overall, 35 studies (27.3%) reported LTFU, and the mean LTFU rate was 4.37%. With the exception of 2 statistical outliers, study characteristics including publication year, number of trial sites, journal discipline, funding source, and intervention type did not predict the odds of reporting LTFU. Compared to 95% of trials reporting participants at eligibility and 100% reporting randomization, only 47% and 57% reported on withdrawal and details of the analysis, respectively. CONCLUSION: The majority of clinical trials in HNC in the United States do not report LTFU, which inhibits the evaluation of attrition bias that may impact the interpretation of significant findings. Standardized reporting is needed to evaluate the generalizability of trial results to clinical practice.

A case report of uremic tumoral calcinosis in the head and neck and literature review of calcified lesions of the head and neck.

Soft-tissue calcifications in the head and neck are relatively common and are the result of a wide variety of benign and malignant pathologies. They can present a diagnostic challenge given the broad range of underlying etiologies. Uremic tumoral calcinosis (UTC) is a rare complication of end-stage renal disease (ESRD) resulting from metastatic soft tissue calcification. Common sites include periarticular soft tissues of the shoulders, elbows, and hands (Pan and Chen, 2016). UTC can also affect the cervical spine and mimic osteosarcomas (Zhou et al., 2018). We present the case of a 71-year-old female with hypertension, left carotid artery stenosis, mitral valve prolapse, and ESRD secondary to diabetes mellitus type II (DMII) on peritoneal dialysis who was found to have large, heterogeneous, bilateral calcified neck masses. Given her clinical history, laboratory results, and imaging findings, she was diagnosed with UTC. In addition to this case, we provide an overview of tumoral calcinosis (TC) and a differential diagnosis for calcified lesions of the head and neck.

Incidence and medical complications of COVID-19 in the total laryngectomy population: A population-based study.

OBJECTIVES: Laryngeal and hypopharyngeal cancers treated with total laryngectomy (TL) may provide a unique avenue for COVID-19 to infect cancer patients. The objective of this investigation was to identify incidence of COVID-19 infection and potential complications in TL patients. MATERIALS AND METHODS: Data was extracted from TriNetX COVID-19 research network from from 2019 to 2021 and ICD-10 codes were utilized to query for laryngeal or hypopharyngeal cancer, and outcomes of interest. Cohorts were propensity score-matched based on demographics and co-morbidities. RESULTS: A query of active patients in TriNetX from January 1, 2019 to December 31, 2021 identified 36,414 patients with laryngeal or hypopharyngeal cancer out of the 50,474,648 active patients in the database. The overall COVID-19 incidence in the non-laryngeal or hypopharyngeal cancer population was 10.8% compared to 18.8% (p < 0.001) in the laryngeal and hypopharyngeal cancer group. Those who underwent TL had a statistically significant increased incidence of acquiring COVID-19 (24.0%) when compared to those without TL (17.7%) (p < 0.001). TL patients with COVID-19 had a higher risk of developing pneumonia RR (risk ratio) 1.80 (1.43, 2.26), death 1.74 (1.41, 2.14), ARDS 2.42 (1.16, 5.05), sepsis 1.77 (1.37, 2.29), shock 2.81 (1.88, 4.18), respiratory failure 2.34 (1.90, 2.88), and malnutrition 2.46 (2.01, 3.01) when matched with those COVID-19 positive cancer patients without TL. CONCLUSIONS: Laryngeal and hypopharyngeal cancer patients had a higher rate of acquiring COVID-19 than patients without these cancers. TL patients have a higher rate of COVID-19 compared to those without TL and may be at a higher risk for sequalae of COVID-19.

Temporal Bone Resection for Squamous Cell Carcinoma of the Lateral Skull Base: Systematic Review and Meta-analysis.

OBJECTIVE: Temporal bone squamous cell carcinoma (TBSCC) is rare and often confers a poor prognosis. The aim of this study was to synthesize survival and recurrence outcomes data reported in the literature for patients who underwent temporal bone resection (TBR) for curative management of TBSCC. We considered TBSCC listed as originating from multiple subsites, including the external ear, parotid, and external auditory canal (EAC), or nonspecifically from the temporal bone. DATA SOURCES: PubMed, Cochrane Library, Embase, and manual search of bibliographies. REVIEW METHOD: A systematic literature review conducted in December 2020 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Survival data were collected from 51 retrospective studies, resulting in a pooled cohort of 501 patients with TBSCC. Compared to patients undergoing lateral TBR (LTBR), patients undergoing subtotal (SBTR) or total (TTBR) TBR exhibited significantly higher rates of stage IV disease (P < .001), positive surgical margins (P < .001), facial nerve involvement (P < .001), and recurrent disease (P < .001). A meta-analysis of 15 studies revealed a statistically significant 97% increase in mortality in patients who underwent STBR or TTBR. On multivariate analysis, recurrent disease was independently associated with worse overall survival (P < .001). On univariate analysis, facial nerve involvement was also associated with decreased overall survival (P < .001). CONCLUSION: Recurrent disease was associated with risk of death in patients undergoing TBR. Larger prospective multi-institutional studies are needed to ascertain prognostic factors for a wider array of postoperative outcomes, including histology-specific survival and recurrence outcomes.

Job market in head and neck surgery: A survey and analysis of recent fellowship graduates.

OBJECTIVE: Recent years have seen increase in individuals pursuing postgraduate fellowships in head and neck (HN) surgery. This has presented concerns about insufficient jobs where graduates can apply their scope of specialized training. METHODS: Data was collected in two manners- a survey and a manual online search of American Head and Neck Society (AHNS) fellowship graduates. A 25-question survey was sent in 2021 to approximately 400 HN fellows who graduated between 2010 and 2020. The AHNS list of graduates from the same years were searched online to collect information including gender, graduation year, fellowship training, and current job practice. RESULTS: Of the 78 survey responses, 64.1 % were male and 34.6 % female. 96.2 % reported ablative, 84.6 % microvascular, and 82.1 % TORS training. Mean number of interviews was 4 with most interviewing during the 3rd quarter (January to March). Majority reported being in academic and university-based practices (79.6 %). Online search was done on 393 graduates. Since 2010 the number of graduates almost doubled. There was a statistically significant increase in females by year (p = 0.022). There was a significant decrease (p = 0.022) in graduates with additional fellowship training from that of their AHNS fellowship. There was also a statistically significant increase in graduates being in academic practices (p = 0.022). CONCLUSION: Despite growing numbers, there appears to be more graduates entering an academic practice, although the definition of an academic HN practice may be evolving. These results provide guidance on how to approach the job search in a select market. LEVEL OF EVIDENCE: II.

The impact of microscopic versus macroscopic extranodal extension in oral cavity squamous cell carcinoma: National cancer database analysis and review of the literature.

OBJECTIVE: To analyze the prognostic significance of microscopic vs macroscopic extranodal extension and to assess the impact of chemoradiation on overall survival among patients with oral cavity squamous cell carcinoma and varying degrees of extranodal extension. METHODS: Utilizing the National Cancer Database, we performed a retrospective cohort study of 7975 patients with oral cavity squamous cell carcinoma and varying degrees of extranodal extension who underwent primary surgical intervention. Propensity-score matched models following Cox regression analyses allowed us to assess the impact of adjuvant radiation alone vs adjuvant chemoradiation on overall survival in patients with microscopic extranodal extension and macroscopic extranodal extension. RESULTS: 7975 patients with oral cavity squamous cell carcinoma were included in the final analysis. Within this cohort, 25.4% had microscopic extranodal extension and 5.2% had macroscopic extranodal extension. On univariate analysis, we found that microscopic and macroscopic extranodal extension were associated with decreased overall survival when compared to those with positive nodes without extranodal extension (HR = 1.67; 95% CI 1.56, 1.79 and HR = 1.88; 95% CI 1.66, 2.14, respectively). On multivariate analysis after propensity-score matching, we found no significant difference in overall survival in patients who received adjuvant radiation alone vs. adjuvant chemoradiation for both microscopic and macroscopic extranodal extension. CONCLUSION: Our data suggest that microscopic extranodal extension in oral cavity squamous cell carcinoma is associated with worse overall survival than patients without extranodal extension following primary surgical intervention with neck dissection. The results of this study also suggest that the addition of chemotherapy to adjuvant radiation may not provide a significant survival benefit in patients with oral cavity squamous cell carcinoma with microscopic and macroscopic extranodal extension. Comprehensive assessment of the benefits of adjuvant chemoradiation in the setting of microscopic vs macroscopic extranodal extension would need to be studied in a randomized controlled trial.

Impact of intraoperative ischemia time on acute complications of head and neck microvascular free tissue transfer: A systematic review and meta-analysis.

BACKGROUND: To evaluate the relationship between intraoperative ischemia time with acute microvascular free tissue transfer (MFTT) complications in head and neck reconstruction. METHODS: A systematic review using PRISMA guidelines was performed. Inclusion encompassed all available studies published and indexed using PubMed, Medline, and Embase. Meta-analyses were performed using the Cochrane Review Manager tool. Methodological Index for Non-Randomized Studies (MINORS), the Revised Cochrane risk-of-bias tool for randomized trials, and the NIH Study Quality Assessment Tool for non-randomized prospective studies. RESULTS: A total of 430 citations were reviewed. 25 were included in our overall qualitative analysis, and 14 for meta-analysis. When comparing ischemia times for flaps with and without complications, no significant difference was observed (p = 0.98). Additionally, in a separate cohort, no significant effect was realized when correlating ischemia time to overall rates and total complications. CONCLUSION: Ischemia time was not significantly different between those with and without acute flap complications.

Medicare reimbursement trends from 2000 to 2020 in head and neck surgical oncology.

BACKGROUND: Considering limited data exploring reimbursement trends at the subspecialty level within head and neck surgical oncology, we sought to characterize these trends for head and neck-specific codes from 2000 to 2020. METHODS: Using the Centers for Medicare and Medicaid Services' Physician Fee Schedule Look-Up Tool, reimbursement data, adjusted to 2020 U.S. dollars, for 37 head and neck surgical oncologic procedure codes were collected from 2000 to 2020. RESULTS: From 2000 to 2020, despite gross reimbursement for all head and neck procedures increasing by 23.2%, when adjusted for inflation, physician reimbursement decreased by 19.4%. Only 4 of 37 examined codes increased in net reimbursement over the study period. CONCLUSION: Medicare reimbursement for the most common head and neck oncologic procedure codes decreased from 2000 to 2020. Further research is necessary to explore the implications of these trends on the delivery of patient care.

Occult nodal metastasis in major salivary gland malignancy: An update from the National Cancer Database.

OBJECTIVES: Malignant salivary gland tumors are rare neoplasms that are vastly heterogenous in their histological patterns and clinical behaviors. As a consequence, studies have lacked the robust sample sizes needed to define treatment strategies. In this study, we used the National Cancer Database to identify the incidence of occult nodal metastasis and effect on overall survival for the most common malignant salivary gland subtypes. A retrospective review of patients in the National Cancer Database with primary site malignancies of major salivary glands between 2004 and 2016 was performed. Subjects included in the study underwent surgical treatment with and without adjuvant radiation and had complete information on TNM pathological stage. MATERIALS AND METHODS: 8,689 patients with primary malignant salivary gland cancer were analyzed. The sample was stratified by histologic subtype. Univariate analysis of lymph node metastasis of the whole cohort showed a higher risk of death (p < 0.001), when compared to those without. Also when comparing occult vs evident metastasis, the risk of death was higher for the latter (p < 0.001). RESULTS AND CONCLUSION: Occult cervical lymph node metastasis ranged from 14.9% to 35.8% in malignant salivary gland cancers, depending on histological subtype. Occult nodal metastasis was a poor prognostic factor with significantly worse overall survival.

Bone Union of Osseous Microvascular Free Tissue Transfer in Mandibular Reconstruction.

OBJECTIVES: Osseous microvascular free tissue transfer (MFTT) is the gold standard for reconstruction for most segmental mandibulectomy defects. The most common osseous MFTT utilized in reconstruction is the fibular, scapular, and osteocutaneous radial forearm (OCRF) free flap. We evaluated postoperative bone union as well as clinical complications following MFTT and the impact of various patient and reconstructive characteristics, including type of osseous MFTT. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary care academic hospital. METHODS: This study examined patients who underwent osseous MFTT for mandibular defects from January 2017 to January 2019. RESULTS: An overall 144 osteotomies in 58 patients were evaluated. Of the 144 junctions, 28 (19.4%) showed radiographic nonunion. Patients who underwent preoperative (odds ratio [OR] = 0.30, P = .027) and postoperative (OR = 0.28, P = .003) radiation had a significantly lower bone union score. Time from surgery to postoperative imaging was associated with higher bone union scores (OR = 1.07, P = .024). When bone union scores were compared among types of MFTT, fibular (OR = 5.62, P = .008) and scapular (OR = 4.69, P = .043) MFTT had significantly higher scores than OCRF MFTT. Twelve (20.7%) patients had postoperative complications. There was no statistically significant correlation between clinical complications and various variables, including type of osseous MFTT. CONCLUSION: Pre- and postoperative radiation and time from surgery have an impact on bone union. Regarding the type of MFTT, fibular and scapular MFTT appeared to have higher bone union when compared with OCRF. There was no impact of bone union or type of osseous MFTT on clinical complications.

Incidence of synchronous malignancies found during triple endoscopy in head and neck cancer.

OBJECTIVES: To investigate the incidence of synchronous malignancies identified during triple endoscopy in patients with head and neck squamous cell carcinoma. METHODS: A retrospective chart review of patients from a tertiary academic medical center was performed. Patients with a primary head and neck squamous cell carcinoma who underwent triple endoscopy were included. Operative, radiographic, and pathology reports were reviewed to evaluate for the presence of synchronous malignancies in the aerodigestive tract diagnosed through endoscopy. Demographics, relevant medical history, including tobacco and alcohol use, and tumor characteristics were recorded. Univariate and multivariate regression analyses were conducted to assess for associations with synchronous malignancy on triple endoscopy. RESULTS: 215 patients were reviewed, 164 of which had a biopsy-positive head and neck squamous cell carcinoma and underwent triple endoscopy. Synchronous lesions were found in 8 patients (4.9%). Of the synchronous lesions, only two were identified on esophagoscopy and bronchoscopy; the remaining six were found on direct laryngoscopy. Clinical comorbidities including smoking and alcohol history, tumor p16 status, and tumor stage were not associated with presence of synchronous lesions. A positive synchronous lesion on positron emission tomography was significantly correlated with finding a synchronous lesion on triple endoscopy (p = 0.006). CONCLUSION: This study shows the incidence of synchronous lesions on triple endoscopy to be closer to 5%. While endoscopic examination can be useful in the anatomic characterization of head and neck malignancies, the low incidence of synchronous malignancies suggests that the need for triple endoscopy may be considered on a case-by-case basis.
