Transcricothyroid Endoscopic Subglottic Surgery for Posterior Glottic Stenosis: A Case Report.
Posterior glottic stenosis (PGS) is a rare but life-threatening condition mostly caused by damage to the interarytenoid mucosa by an endotracheal tube. In surgical treatment of PGS, airway patency is prioritized, and the laryngeal functions involved in swallowing and phonation are considerably sacrificed. In the majority of cases, lateralization of a vocal fold or partial excision of a vocal fold and arytenoid cartilage results in glottal closure insufficiency and deterioration of phonatory function. We present the first report of transcricothyroid endoscopic subglottic surgery to treat a 46-year-old man with PGS who was intubated for 10 days. Postoperative hypofunction was not observed in the aerodynamic examination and acoustic analysis, and phonatory function has been maintained within normal limits.
