Acquired nasopharyngeal stenosis after radiation treatment for nasopharyngeal carcinoma.

INTRODUCTION: Nasopharyngeal stenosis (NPS) is a rare and morbid complication following radiation therapy for nasopharyngeal carcinoma. This review provides an update on management and prognosis. METHODS: A comprehensive PubMed review using the terms "nasopharyngeal stenosis," "choanal stenosis," and "acquired choanal stenosis" was performed. RESULTS: Fourteen studies identified 59 patients who developed NPS after radiotherapy for NPC. 51 patients underwent endoscopic nasopharyngeal stenosis excision by cold technique (80-100% success). The remaining 8 underwent carbon dioxide (CO2) laser excision with balloon dilation (40-60% success). Adjuvant therapies included postoperative topical nasal steroids in 35 patients. The need for revision was 62% in the balloon dilation group, vs 17% in the excision group (p-value <0.01). CONCLUSION: When NPS occurs after radiation, primary excision of scarring is the most effective method of management with less need for revision surgery relative to balloon dilation.

Point-of-care ultrasound scan as the primary modality for evaluating parotid tumors.

Objectives: This study aimed to explore ultrasonography as a single imaging modality for the initial assessment of parotid lesions compared to computed tomography (CT) and magnetic resonance imaging (MRI). Methods: A retrospective cross-sectional study was performed on 264 parotid gland lesions evaluated in a dedicated point-of-care ultrasound (POCUS) clinic with concurrent fine needle biopsy (FNB). Two hundred and nine of these lesions also underwent CT or MRI imaging. Histopathology results, when available, were recorded and compared to imaging impressions. Results: Surgeon-performed POCUS classified parotid masses accurately when compared to final histopathology (90/96, 94%). Using predefined criteria, POCUS determined the nature of parotid lesions more definitively than the descriptive CT or MRI radiology reports (p <.001). Sub-analysis showed that ultrasonography was able to distinguish between benign pathologies with high degree of accuracy (Warthin tumor-82%, pleomorphic adenoma-64%). Conclusions: POCUS can accurately distinguish between benign and malignant parotid lesions. POCUS may suffice as the only imaging study for benign lesions, obviating the need for additional cross-sectional imaging. This can be combined with fine needle or core biopsy in the same visit, resulting in expedient diagnosis, low cost, and lack of radiation exposure. Level of Evidence: 2b, individual cross-sectional cohort study.

Milan system for reporting salivary gland cytopathology: Adoption and outcomes in a community setting.

BACKGROUND: Milan system for reporting salivary gland cytopathology (MSRSGC) was introduced to standardize reporting of salivary gland cytopathology. METHODS: A retrospective review of ultrasound-guided fine needle biopsy of salivary gland lesions was performed between January 2018 and May 2021 at a community otolaryngology practice. Diagnostic accuracy and rate of diagnostic sialoadenectomy were calculated. RESULTS: A total of 203 FNAs (fine needle aspiration) were performed in 184 patients. MSRSGC was utilized in 87/203 cytopathology reports, with a diagnostic accuracy of 84%. Descriptive reporting was used in 115 FNAs, with a diagnostic accuracy of 89% (p = 0.68). Sialoadenectomy rate was 41% for MSRSGC compared to 36% in descriptive cytopathology (p = 0.48). CONCLUSIONS: MSRSGC is as accurate as descriptive cytopathology and the rate of diagnostic sialoadenectomy between both groups is similar in our community. The MSRSGC brings uniformity and standardization to the FNA reporting process.

Nasolacrimal Duct Obstruction: An Unusual Presentation of Sarcoidosis.

Lacrimal drainage system disorders leading to epiphora are a common ophthalmologic complaint. When such a patient is identified, the ophthalmologist frequently collaborates with the otolaryngologist to perform a dacryocystorhinostomy (DCR). In rare cases, sinonasal sarcoidosis may lead to nasolacrimal duct obstruction (NLD) and dacryocystitis. A 48-year-old Caucasian female was referred to the Otolaryngology clinic for evaluation of a 6-month history of persistent right-sided nasal obstruction and epiphora. After physical examination and computerized tomography (CT) scan, she was diagnosed with right NLD with dacryocystitis. The patient underwent right endoscopic DCR. Pathology from the lacrimal bone and nasal tissue demonstrated noncaseating granulomas suggestive of sarcoidosis. Postoperative evaluation including lung CT scan confirmed systemic sarcoidosis. Nasolacrimal duct obstruction very rarely is the presenting symptom in patients with sarcoidosis. Imaging is necessary to rule out other causes of NLD, and histopathology is essential for diagnosis. Noncaseating granulomas are found along the nasal tissue and lacrimal sac, specifically in the subepithelial layer. Treatment consists of DCR, either endoscopic or external. Both approaches achieve long-lasting resolution of symptoms but may require revision from inflammation and scarring. There is no consensus on the use of intraoperative or postoperative steroids.

Survival and prognostic factors of salivary gland malignant mixed tumor-not otherwise specified: A population-based analysis.

OBJECTIVE: Malignant mixed tumors of the salivary gland are a group of neoplasms comprised of carcinoma-ex-pleomorphic adenoma, carcinosarcoma, and metastasizing pleomorphic adenoma. An alternative classification, malignant mixed tumor-not otherwise (MMT-NOS), is a diagnosis of exclusion for neoplasms that do not fit the previous histologically profiled subtypes. The objective was to provide a comprehensive assessment of MMT-NOS and determine prognostic factors. METHODS: This retrospective cohort study queried the Surveillance, Epidemiology, and End Results database for patient and tumor characteristics of US patients with MMT-NOS of the major salivary glands from 1973 to 2016. Kaplan-Meier and Cox regression analysis were performed to determine 5-year survival and prognostic factors. RESULTS: 434 patients were identified with a mean age at diagnosis of 61.5 years. The majority of neoplasms were high grade and stage (70.8% grade III/IV; 63.8% stage III/IV). Extraparenchymal extension (40.6%) and lymph node involvement (28.5%) were common; distant metastases (2.4%) were rare. Treatment included surgery (93.0%), radiation (51.6%), and chemotherapy (10.4%). Facial nerve sacrifice was common (50.8%). Median survival was 66.5 months. 5-year overall and disease-specific survival were 65.7% and 83.0%, respectively. In multivariate analysis, nodal involvement (HR 7.0; P < 0.001), surgery-radiation-chemotherapy (HR 6.1; P = 0.02), extraparenchymal extension (HR 2.50; P = 0.04), and tumor size >4 cm (HR 1.3; P = 0.03) were prognostic factors. CONCLUSION: Despite high stage and grade at diagnosis, MMT-NOS portends a good 5-year prognosis and low rate of distant metastasis. Prognostic factors were nodal involvement, tumor size, and extraparenchymal extension.

Pediatric Septal Perforation Repair With the Endoscopic Anterior Ethmoid Artery Flap.

Pediatric nasal septal perforations can lead to crusting, obstruction, whistling, and recurrent epistaxis. Current approaches for pediatric nasal septal repair center on combination endonasal and external approaches. Herein we describe the successful utilization of a purely endoscopic anterior ethmoid artery flap, an established technique in adults, for nasal septal perforation repair in 3 children aged 12 to 13 years who presented with septal perforations ranging in size from 6 to 12 mm. Successful closure was achieved with an endoscopic anterior ethmoid artery flap, with all patients achieving complete closure and symptom resolution. Children with nasal septal defects are typically treated with temporizing measures until early adulthood, when definitive open repair may be performed. Our initial experience with the anterior ethmoid artery flap technique suggests that this surgery may be easily performed in children as young as 12 years, without the use of previously described adjunctive procedures such as turbinate translocation.

A pilot study on pediatric mononucleosis presenting with abscess.

CONTEXT: To describe this new clinical entity, diagnosis, and potential management of pediatric intratonsillar/peritonsillar abscesses in children affected by infectious mononucleosis. METHODS: After institutional review board approval, a retrospective chart review of patients who underwent testing for infectious mononucleosis and also had a computed tomography scan of the head and neck was completed. Those who did not have imaging showing the palatine tonsils and those with insufficient testing to diagnose infectious mononucleosis were excluded. MAIN FINDINGS: One hundred patients were included in the study; 15 had a peritonsillar abscess and 29 had an intratonsillar abscess. Four of the patients with a peritonsillar abscess (26.7%) had a positive Monospot or Epstein-Barr virus IgM result, and two of 15 (13.3%) had positive rapid strep or culture results. Of the 29 patients with an intratonsillar abscess, eight (27.6%) had a positive Monospot or Epstein-Barr virus IgM result while two (6.9%) had a positive rapid strep or culture result. Of those with bilateral intratonsillar abscess, five of 12 (41.7%) patients showed laboratory markers for infectious mononucleosis compared with three of 17 (17.6%) with unilateral intratonsillar abscess. This difference was not statistically significant (Fischer's, p = 0.218). CONCLUSION: In our cohort of patients undergoing computed tomography scan and acute infectious mononucleosis testing, patients with intratonsillar and peritonsillar abscess tested positive for mononucleosis markers more commonly than for streptococcus markers. Recognizing uncomplicated intratonsillar and peritonsillar abscess in the setting of infectious mononucleosis in these pediatric patients may help tailor management in this population.

The Índice Flesch-Szigriszt and Spanish Lexile Analyzer to evaluate Spanish patient education materials in otolaryngology.

OBJECTIVES/HYPOTHESIS: Evaluate the reading difficulty of Spanish patient education materials using the validated Índice Flesch-Szigriszt (INFLESZ) and Spanish Lexile Analyzer, and to identify relationships between English and Spanish readability formulas. STUDY DESIGN: Cross-sectional analysis. METHODS: All otolaryngology-related patient education articles written in Spanish from the health libraries of the top 10 US News & World Report-ranked hospitals, top 10 Doximity-ranked otolaryngology residencies, the American Academy of Otolaryngology-Head and Neck Surgery website, and the US National Library of Medicine online section on ears, nose and throat were collected. Reading difficulty was assessed using the INFLESZ and Spanish Lexile Analyzer. Additional readability assessments included the traditional English tools: Flesch-Kincaid Grade Level, Flesch Reading Ease Score, and the Simple Measure of Gobbledygook score. RESULTS: A total of 497 articles were reviewed. The average INFLESZ score for all articles was 57.75, which is considered normal and requires the reading ability of a student who finished Escuela Secundaria Obligatoria or 10th grade equivalent in the United States. The average Spanish Lexile measure for all articles was 1062L, equivalent to a reading level between the 6th and 12th grade. English readability tools calculated a more difficult reading level compared to Spanish tools when performed on the same text. CONCLUSIONS: Current Spanish patient education materials in otolaryngology may be too difficult for the average Spanish-speaking reader to understand. Future improvements may be warranted to improve the readability of educational materials and increase health literacy. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:E21-E26, 2018.
