Abstract
A 77-year-old male was seen with a chief complaint of dyspnea-like sensation. Mirror examination and fiberscopy revealed bulging at the anterior wall of the subglottic space. Laryngomicrosurgery was performed under general anesthesia. Operative finding revealed hard mass like ossification at the above mentioned area. X-ray CT examination and xerography demonstrated bony density area on the center of the inner side of the thyroid cartilage. This area corresponded to the location of the attachment of the median cricothyroid ligament to the thyroid cartilage. This case was suggested to be the ossification of the median cricothyroid ligament. There has been no report of the ossification of the median cricothyroid ligament in the literature.
