Wegener's granulomatosis causing subglottic stenosis: Experiences at a tertiary care hospital of the Eastern India

Objectives: To study the clinical profile and management of Wegener's granulomatosis (WG) with subglottic stenosis (SGS) at a tertiary teaching hospital in Eastern India. Methods: This prospective study incorporated a case series of six patients treated between 2007 and 2015 for WG with SGS. The demographic details of the patients, such as age, sex, clinical presentation, laryngeal endoscopy, imaging, laboratory tests, and medical and surgical options, are described. Results: Of the six patients, five had laryngeal symptoms, such as hoarseness or breathing difficulty, at the time of presentation. There were four female and two male patients ranging in age from 14 to 62 years. The diagnosis of all six patients was confirmed via histopathological examination. Of the six patients, one had isolated subglottic involvement, and four had a positive antineutrophilic cytoplasmic autoantibody (C-ANCA) test on presentation. All of the patients received immunosuppressant and steroid therapies at the time of diagnosis. Five patients required tracheostomy with subglottic dilatation with cold steel instruments followed by the local injection of steroids and mitomycin-C application. Four patients have shown clinical improvement. Conclusion: Although WG is a rare clinical condition, it is often confused with common ailments, which delays diagnosis, and it may involve the subglottis. The subglottis is a vital part of the laryngotracheal airway, and mild obstruction can be life threatening. The accurate and timely diagnosis of WG helps to prevent life-threatening complications, such as SGS.
