Objectives/Hypothesis: Awake, unsedated in‐office upper airway procedures are performed frequently and have high completion rates, yet less is known about the patients' pain experience and potentially influencing factors. It is also unclear if patients' pain experiences become worse with repeated procedures. We identified procedure‐ and patient‐related factors that might influence procedural completion and pain scores. Study Design: Retrospective chart review. Methods: Pre‐, intra‐, and post‐procedure pain scores were collected prospectively for awake unsedated upper airway procedures performed at a single institution over a 5‐year period. Patient factors reviewed were demographics, body mass index, psychiatric and/or pain diagnosis, and related medications. Procedure factors reviewed were procedure type, route, side, and performance of the same procedure multiple times. Patients reported their pain level before, during, and after the procedure using a standard 0 to 10 scale. Maximum pain score change (PΔmax), or the difference between highest and lowest reported pain levels, was calculated. Descriptive and multivariate analyses were performed. Results: Procedure completion was 98.7% for 609 first time patients and 99.0% in 60 patients undergoing 292 repeat procedures. PΔmax did not covary with age, gender, or BMI. PΔmax covaried with pain and psychiatric conditions and associated medications. PΔmax was highest for injection medialization and lowest for tracheoscopy. PΔmax decreased over time for those undergoing multiple identical procedures. Conclusions: Procedures were performed with a very high completion rate and low pain scores. Age, sex, and BMI did not affect pain experience. A combination of pain and psychiatric conditions did. Injection medialization had the highest PΔmax and tracheoscopy the lowest.

Objectives/hypothesis: Chronic frontal sinus infection is managed with a combination of medical and surgical interventions. Frontal bone osteomyelitis due to recurrent infection following trauma or prior open surgery may require more significant debridement. Free tissue transfer may allow for extensive debridement with replacement of tissue, and definitive eradication of osteomyelitis.Study Design: Retrospective chart review.Methods: Patients undergoing free flap obliteration of the frontal sinus for frontal bone osteomyelitis at a single institution were included in the study. Clinical, radiologic, and surgical data were collected. Surgeries before and after free flap obliteration were compared by Wilcoxon signed rank test.Results: Fifteen patients were identified; however, one patient had less than 6 months of follow-up and was excluded from analysis. Of the remaining 14 patients, mean follow-up duration was 26 months (range, 6-120 months). Mean number of surgeries prior to free flap was 3.7 (range, 1-8 surgeries). Free flap obliteration resolved chronic frontal sinusitis in all patients. Two patients experienced postoperative infection, and the overall complication rate was 29%. Eight patients underwent cranioplasty (six immediate, two delayed) without complication. All patients received planned courses of postoperative antibiotics. A statistically significant decrease in the number of surgeries after free flap obliteration was observed P ≤ .01).Conclusions: Extensive debridement followed by free tissue transfer and antibiotics offers a definitive treatment for complicated, recurrent frontal osteomyelitis. Simultaneous cranioplasty provides immediate protective and aesthetic benefit without complication. Consideration should be given for free tissue transfer and cranioplasty earlier in the algorithm for treatment of refractory frontal sinus osteomyelitis.Level Of Evidence: 4 Laryngoscope, 129:1497-1504, 2019.

Objective To determine the volume of ventral skull base tumor removed following endoscopic endonasal (EEA) resection using MRI-based volumetric analysis and to evaluate the inter-rater reliability of such analysis. Design Retrospective case series. Setting Academic tertiary care hospital. Participants EEA patients November 2012 to August 2015. Main Outcome Measures Volumetric analysis of pre- and immediately postoperative MR imaging was performed independently by two investigators. The percentage of total tumor resected was evaluated according to resection goal and tumor type. Results A total of 39 patients underwent resection. Intraclass correlation coefficients between the raters were 0.9988 for preoperative and 0.9819 for postoperative images. Tumors (and average percentage removed) included 17 nonsecreting pituitary adenomas (95.3%), 8 secreting pituitary adenomas (86.2%), 4 meningiomas (81.6%), 3 olfactory neuroblastomas (100%), 2 craniopharyngiomas (100%), 1 large B-cell lymphoma (90.5%), 1 germ cell neoplasm (48.3), 1 benign fibrous connective tissue mass (93.4%), 1 epidermoid cyst (68.4%), and 1 chordoma (100%). For tumors treated with intent for gross total resection, 96.9 ± 4.8% was removed. Conclusion EEAs achieved tumor resection rates of ~97% when total resection was attempted. The radiographic finding of residual tumor is of uncertain clinical significance. The volumetric analysis employed in this study demonstrated high inter-rater reliability and could facilitate further study. [ABSTRACT FROM AUTHOR]

Background  Biphenotypic sinonasal sarcoma is a recently described malignancy showing dual differentiation with both myogenic and neural elements. Due to its histologic similarities to other sinonasal malignancies, it is a diagnostic challenge. Objective  The main purpose of this article is to report a case of biphenotypic sinonasal sarcoma and to consolidate data and provide a comprehensive review regarding pathological differences between biphenotypic sarcoma and other sinonasal malignancies and diagnostic modalities used for biphenotypic sarcoma. Material and Methods  A systematic review of all cases of biphenotypic sinonasal sarcoma was performed using electronic databases (PubMed and Medline). Data collected included age, gender, symptoms, sub-site of origin, immunophenotyping, metastasis, recurrence, treatment, duration of follow-up, and survival outcomes. Results  Ninety-five cases of biphenotypic sarcoma were found with mean age at diagnosis of 52.36 years (range, 24-87 years). Female to male ratio was 2.27:1. Extra-sinonasal extension was present in 28%. Immunophenotyping revealed that S-100 and SMA (smooth muscle actin) were consistently positive, while SOX-10 was consistently negative. PAX3-MAML3 fusion [t (2; 4) (q35; q31.1)] was the most common genetic rearrangement. Surgical excision with or without adjuvant radiotherapy was the most frequent treatment modality used. Recurrence was observed in 32% of cases with follow-up. None of the cases reported metastasis. Three patients had died at the time of publication that included one case with intracranial extension. Conclusion  Biphenotypic sarcoma is distinct sinonasal malignancy with unique clinicopathological features. Testing involving a battery of myogenic and neural immunomarkers is essential for diagnostic confirmation and is a clinically useful endeavor when clinical suspicion is high.
