Objective: With advancements in respiratory interventional techniques, bronchoscopic intervention technology has emerged as a viable approach for managing postintubation tracheal stenosis (PITS). However, there was a paucity of research investigating the potential impact of stenosis characteristics and morphology (such as stenosis degree, length, type, and morphology) on bronchoscopic intervention treatment prognosis for PITS patients. This study was to assess the impact of various preoperative stenosis characteristic factors on the bronchoscopic cure rate among patients.

Laryngeal granuloma, vocal process granuloma, or post-intubation granuloma are benign, inflammatory lesions of the arytenoid cartilage vocal process. The etiology of laryngeal granulomas is multifactorial, such as chronic irritation due to endotracheal intubation, vocal cord injury or trauma, and gastroesophageal reflux disease. They can arise postoperatively after mucosal injury due to orotracheal intubation.

The diagnosis of head and neck spindle cell squamous carcinoma (SC-SCC) is often challenging. Lesions with a prominent inflammatory infiltrate and reactive vessels may have a granulation tissue-like appearance, therefore being difficult to distinguish from reactive lesions, like contact ulcers, post-intubation granulomas, inflammatory pseudotumors, or benign vascular lesions. In this study, we analyzed the clinicopathological features of a series of 17 head and neck SC-SCC with granulation tissue-like appearance.

This case concerns a 54-year-old patient presenting to the Emergency Department with acute dyspnea and a loud stridor. Fiberscopy showed a large subglottic granuloma, most likely resulting from recent endotracheal intubation because of a severe COVID-19 infection. Increase in COVID-19 associated intubations may result in an increase of post-intubation granulomas.

Article Synopsis
- - Severe cases of COVID-19 can lead to orotracheal intubation (OTI), which may result in a complication known as post-intubation laryngeal injury (PI-LI), potentially occurring more frequently in COVID-19 patients.
- - A study reported on six COVID-19 patients who developed dyspnea post-recovery, with all showing abnormal findings during endoscopy and five having undergone OTI for a median of 9 days.
- - The study highlights the critical need for healthcare providers to recognize PI-LI as a potential issue in patients with dyspnea after COVID-19, suggesting that otolaryngologists should conduct endoscopic examinations for proper diagnosis and treatment.
