Abstract
Congenital subglottic stenosis (C-SGS) is a rare disease. In the case of severe stenosis, decannulation is often difficult. Our patient was a 4-year-old girl. Respiratory failure immediately after birth prompted the emergency tracheotomy. When she was 3 years old, a high degree of subglottic stenosis continuous from the vocal cord, bilateral vocal cord paralysis, and glottis stenosis were found. The stenosis did not improve after 1 year follow-up; therefore, we performed single-stage extended partial cricotracheal resection (ePCTR) and lateralization of the vocal cord (Ejnell procedure) simultaneously. Postoperative adhesion around the anterior laryngeal commissure and the granulation tissue around the right vocal cord made extubation difficult. We resected the adhesion and granulation tissue under a microlaryngoscope and enabled extubation on POD 19. She went home 3 months after surgery. At 1 year postsurgery, she remained well without any complication. For severe C-SGS, single-stage ePCTR, lateralization of the vocal cord, and postoperative microlaryngoscopic surgery were effective and enabled decannulation.
