Imbrication of Anterior Digastric with Advancement of the Posterior Digastric and Its Implications in Neck Aesthetics.

Background: To describe a novel technique to modify the proportional length of the anterior-to-posterior digastric muscles to improve neck aesthetics. Objective: To provide an objective measure to quantify neck rejuvenation and a novel technique to adjust the digastric ratio. Design: We retrospectively compared 52 patients who had neck rejuvenation with or without digastric manipulation. Preoperative and postoperative images were analyzed and compared with computer software using a novel analysis technique to measure the digastric ratio and neck height. Distances between the menton, cervical point (CP), and gonion were measured. Results: The anterior-to-posterior digastric ratio improved an average of 26.5% (p < 0.01) in the new technique group, 15.9% in the control group. Distance of the CP to the inferior edge of the mandible decreased an average of 13.9% using the new technique. Conclusion: The ratio of anterior-to-posterior digastric muscle appears to improve as well as the neck height with manipulation of the digastric muscles.

Determining the association of insurance coverage and survival outcomes in patients with olfactory neuroblastoma utilizing machine learning.

KEY POINTS: We use machine learning to examine health insurance and mortality in olfactory neuroblastoma. Private insurance significantly improved survival even after adjusting for confounders. The regression model also found no statistical difference between Medicare and no insurance.

Microbial Changes Associated With Oral Cavity Cancer Progression.

OBJECTIVE: To examine the oral microbiome in the context of oral cavity squamous cell carcinoma. STUDY DESIGN: Basic science research. SETTING: Academic medical center. METHODS: Oral swabs were collected from patients presenting to the operating room for management of oral cavity squamous cell carcinoma and from age- and sex-matched control patients receiving surgery for unrelated benign conditions. 16S ribosomal RNA (rRNA) sequencing was performed on genetic material obtained from swabs. A bacterial rRNA gene library was created and sequence reads were sorted into taxonomic units. RESULTS: Thirty-one control patients (17 males) and 35 cancer patients (21 males) were enrolled. Ages ranged from 23 to 89 (median 63) for control patients and 35 to 86 (median 66) for cancer patients. Sixty-one percent of control patients and 63% of cancer patients were smokers. 16S analyses demonstrated a significant decrease in Streptococcus genera in oral cancer patients (34.11% vs 21.74% of the population, p = .04). Increases in Fusobacterium, Peptostreptococcus, Parvimonas, and Neisseria were also found. The abundance of these bacteria correlated with tumor T-stage. CONCLUSION: 16S rRNA sequencing demonstrated changes in bacterial populations in oral cavity cancer and its progression compared to noncancer controls. We found increases in bacteria genera that correspond with tumor stage-Fusobacteria, Peptostreptococcus, Parvimonas, Neisseria, and Treponema. These data suggest that oral cancer creates an environment to facilitate foreign bacterial growth, rather than implicating a specific bacterial species in carcinogenesis. These bacteria can be employed as a potential marker for tumor progression or interrogated to better characterize the tumor microenvironment.

Right Vocal Cord Paralysis Caused by Histoplasmosis: A Case Report.

OBJECTIVES: Histoplasma capsulatum is a prevalent dimorphic fungus, reaching an exposure rate of 90% in endemic areas such as the Midwest and Central United States. We report an unusual presentation of dysphonia due to right vocal cord paralysis caused by mediastinal lymphadenopathy from histoplasmosis. METHODS: A 73-year-old male presented to an otolaryngology clinic with 4 months of hoarseness. Flexible strobolaryngoscopy demonstrated right vocal cord paralysis in lateral position and a full length glottic gap. Computerized tomography (CT) scan showed enlargement of a right paratracheal node. RESULTS: A lymph node biopsy was obtained and showed histoplasmosis. He was treated with a 3-month course of pozaconazole. He then received a vocal cord medialization injection 2 months after symptom onset, which produced favorable improvement of his symptoms at 8-month follow up. CONCLUSIONS: One other case report in the literature has reported left vocal cord paralysis related to histoplasmosis. This first case of right vocal cord paralysis was extremely unusual and is not often included in the differential diagnosis of vocal cord paralysis.

Development and Validation of a Decision Analytical Model for Posttreatment Surveillance for Patients With Oropharyngeal Carcinoma.

Importance: Clinical practice regarding posttreatment radiologic surveillance for patients with oropharyngeal carcinoma (OPC) is neither adapted to individual patient risk nor fully evidence based. Objectives: To construct a microsimulation model for posttreatment OPC progression and use it to optimize surveillance strategies while accounting for both tumor stage and human papillomavirus (HPV) status. Design, Setting, and Participants: In this decision analytical modeling study, a Markov model of 3-year posttreatment patient trajectories was created. The training data source was the American College of Surgeon's National Cancer Database from 2010 to 2015. The external validation data set was the 2016 International Collaboration on Oropharyngeal Cancer Network for Staging (ICON-S) study. Training data comprised 2159 patients with OPC treated with primary radiotherapy who had known HPV status and disease staging information. Patients with American Joint Committee on Cancer, 7th edition stage III to IVB disease and those with clinical metastases during the time of primary treatment were included. Data were analyzed from August 1 to October 31, 2020. Main Outcomes and Measures: Main outcomes included disease stage and HPV status, specific disease transition probabilities, and latency of surveillance regimens, defined as time between recurrence incidence and disease discovery. Results: Training data consisted of 2159 total patients (1708 men [79.1%]; median age, 59.6 years [range, 40-90 years]; 401 with stage III disease, 1415 with stage IVA disease, and 343 with stage IVB disease). Cohorts predominantly had HPV-negative disease (1606 [74.4%]). With model-optimized regimens, recurrent disease was discovered a mean of 0.6 months (95% CI, 0.5-0.8 months) earlier than with a standard surveillance regimen based on current clinical guidelines. Recurrent disease was discovered using the optimized regimens without significant reduction in sensitivity. Compared with strategies based on reimbursement guidelines, the model-optimized regimens found disease a mean of 1.8 months (95% CI, 1.3-2.3 months) earlier. Conclusions and Relevance: Optimized, risk-stratified surveillance regimens consistently outperformed nonoptimized strategies. These gains were obtained without requiring any additional imaging studies. This approach to risk-stratified surveillance optimization is generalizable to a broad range of tumor types and risk factors.

In-office Endonasal Minor Revision Rhinoplasty.

The revision rhinoplasty presents many unique challenges to the facial plastic surgeon. While many cases will require a full revision in the operating room, there are several isolated deformities which may be repaired in the office via an endonasal approach. This provides many benefits to the patient and surgeon including decreased cost, shorter recovery time, avoidance of general anesthesia, and less discomfort. It is critical to identify defects appropriate for endonasal repair, establish clear expectations with the patient, and work within one's skill set and level of experience. The surgeon who can comfortably navigate both open and endonasal techniques can offer their patients a comprehensive set of solutions for revision rhinoplasty. In this article we outline the defects amenable to this type of repair as well as technical considerations for each defect addressed. We hope it serves as a useful framework for the range of deformities the rhinoplasty surgeon may take on for in-office repair.

Functional outcomes after extracapsular dissection with partial facial nerve dissection for small and large parotid neoplasms.

PURPOSE: Multiple surgical options exist for benign parotid tumors without agreement upon a single, best approach. We evaluated the short-term outcomes and rate of complications using the ECD-FND technique for small and large parotid neoplasms involving the superficial and deep lobes of the parotid gland using a categorical approach. MATERIAL AND METHODS: A single surgeon retrospective cohort study with analysis of patient demographics, outcomes, and complication rates was conducted of patients undergoing the ECD-FND for benign parotid neoplasm. Cases from May 2014 to May 2020 with at least 6 months follow up were considered. Complications were assessed by chart review and tumors were categorized by size and by European Salivary Gland Society (ESGS) classification assigned by a neuroradiologist. RESULTS: Fifty-one patients who underwent ECD-FND of suspected benign parotid mass met inclusion criteria. The most common histology was pleomorphic adenoma (56.9%) followed by Warthin's tumor (19.6%). Overall rate of complications was 31.4% with no major complications. Most patients (88.2%) had normal facial nerve function immediately after surgery and all recovered completely in the post operative period. Sialocele occurred in 15.7% of patients with 87.5% resolved within one month and seromas occurred in four patients (7.8%). There was no significant difference in complication rates between the size of tumor (p = 0.889), depth (p = 0.770), or ESGS classification (p = 0.846). CONCLUSIONS: The ECD-FND technique achieved excellent facial nerve outcomes among our cohort, which included a - proportion of large (>3 cm) and deep lobe tumors. Complications rates and outcomes were similar for larger and deep lobe tumors that underwent a ECD-FND approach. LEVEL OF EVIDENCE: 3.

Effect of margin status and pathological grade in treatment of sinonasal mucoepidermoid carcinoma.

OBJECTIVES: The purpose of this study was to investigate the association of demographic factors, grade, margin status, and treatment modalities for overall survival in patients with sinonasal mucoepidermoid carcinoma (SNMEC). STUDY DESIGN: Retrospective database review. METHODS: The National Cancer Database was queried for patients of all ages with SNMEC between 2004 and 2015. Univariate Kaplan-Meier and multivariate Cox regression analyses were performed to evaluate the association of suspected prognostic factors with overall survival. Subgroup analysis by margin status and grade was performed. RESULTS: A total of 239 patients with SNMEC were included in the analysis. The 5-year overall survival was 63.6%. Prognostic factors associated with decreased survival include age over 70 years (P = .027), sphenoid primary site (P = .002), and advanced-stage malignancy (P = .024). Improved survival was associated with surgery achieving negative margins (P = .001). Adjuvant radiation was associated with improved survival (hazard ratio [HR] = 0.25, P = .015) in the negative-margin group but was not found to be a statistically significant factor in the positive-margin group (HR = 0.66, P = .509). CONCLUSIONS: This investigation is the largest to date to analyze the association of treatment modalities with overall survival in SNMEC and subgroup analysis by histopathologic grade and surgical margin status of treatment outcomes. Surgery remains the mainstay of treatment in patients with SNMEC. However, administration of radiation may confer survival benefit to patients with negative margins.

Treatment modalities in sinonasal mucosal melanoma: A national cancer database analysis.

OBJECTIVES/HYPOTHESIS: The purpose of this study was to investigate the association of demographic factors, tumor stage, and treatment modalities for overall survival in patients with sinonasal mucosal melanoma (SNMM). STUDY DESIGN: Retrospective database review. METHODS: The National Cancer Database was queried for patients of all ages with SNMM between 2004 and 2015. Univariate Kaplan-Meier and multivariate Cox regression analyses were performed to evaluate the association of suspected prognostic factors with overall survival. RESULTS: A total of 1,874 patients with SNMM were included in the analysis. The 5-year overall survival was 24%. Prognostic factors associated with decreased survival include advanced age (hazard ratio [HR]: 1.02, 95% confidence interval [CI]: 1.01-1.03), T4 disease (HR: 1.44, 95% CI: 1.09-1.89), and presence of distant metastases (HR: 3.22. 95% CI: 2.06-5.04). Improved survival was associated with surgical resection only when margins were negative (HR: 0.44; 95% CI: 0.30-0.65). In patients with metastatic disease, administration of immunotherapy (HR: 0.14; 95% CI: 0.04-0.49) was associated with improved survival. Surgical approach, radiotherapy, and chemotherapy were nonsignificant predictors of survival. CONCLUSIONS: This investigation is the largest to date to analyze the association of treatment modalities with overall survival in SNMM. Surgery remains the mainstay of treatment in patients with SNMM. However, administration of immunotherapy may confer survival benefit to patients with metastatic disease.

Survival in low-grade and high-grade sinonasal adenocarcinoma: A national cancer database analysis.

OBJECTIVES/HYPOTHESIS: The purpose of this study was to investigate survival differences between low-grade and high-grade sinonasal adenocarcinoma (SNAC) by examining demographics, tumor characteristics, and treatment modalities. STUDY DESIGN: Retrospective database analysis. METHODS: The National Cancer Database was queried for patients with SNAC between 2004 and 2015. Univariate and multivariate analyses were performed for all cases of SNAC. Subsequent analysis focused on low-grade (grade 1 and grade 2) and high-grade (grade 3 and grade 4) SNAC. RESULTS: A total of 1,288 patients with SNAC were included in the main cohort and divided into low grade (n = 601) and high grade (n = 370). The 5-year overall survival for all patients, low-grade, and high-grade was 54%, 64%, and 38%, respectively. Prognostic factors associated with decreased survival for the main cohort include advanced age (hazard ratio [HR]: 1.04; 95% confidence interval [CI]: 1.03-1.06), Charlson-Deyo score (HR: 1.37; 95% CI: 1.05-1.78), grade 2 (HR: 2.21; 95% CI: 1.26-3.86], grade 3 (HR: 3.67; 95% CI: 2.09-6.45), and grade 4 (HR: 3.31; 95% CI: 1.38-7.91). Radiotherapy was associated with improved overall survival for high-grade SNAC (HR: 0.41; 95% CI: 0.24-0.70) but not for low-grade SNAC (HR: 1.05; 95% CI: 0.59-1.85). CONCLUSIONS: This investigation is the largest to date analyzing the association of treatment modalities with overall survival in SNAC. Surgery remains paramount to treatment, with radiotherapy offering additional survival benefit for high-grade SNAC. Administration of chemotherapy was not associated with improved survival.
