The patient was a 12-year-old boy. Immediately after birth, he presented cyanosis, a laryngeal fiber scan revealed subglottic stenosis, and emergency tracheostomy was performed at another hospital. Since then, the tracheal cannula had been changed by the local physician and the patient had remained under observation; however, no active therapeutic intervention had been performed. Then, the patient was referred to our hospital for a thorough examination and treatment, with the aim of closing the tracheal hole. Preoperative CT raised the suspicion of chondroma and chondrosarcoma. For the subglottic stenosis, we performed subglottic laryngectomy and T-tube implantation through a laryngeal crown. The specimen was not neoplastic, rather it was cartilage tissue. We diagnosed the patient with congenital subglottic stenosis due to an anomaly of the cricoid cartilage. The postoperative course was good, and the T-tube was removed approximately 3 months after the operation. The tracheal hole was closed at approximately 1 year and 4 months after the operation. In this article, we report a case of congenital subglottic stenosis for which surgical treatment was successfully performed, and also discuss the pathogenesis and pathophysiology of the disease with some review of the relevant literature.
