Abstract

Trauma, congenital malformation and aging process can be a cause of the deviation of laryngeal prominence in the thyroid cartilage. Among these, the senility is the most common cause. Usually, ossification in the thyroid cartilage has occurred symmetrically, but the asymmetrical event leads to the shift of laryngeal prominence. Also, such deformity can provoke protrusion of false vocal fold. A 75-year-old man with hoarseness and globus sense in throat visited our clinic. Five years ago, he experienced a blunt trauma on left midline neck and had a concave deformity in the left thyroid cartilage lamina. Laryngoscopic findings revealed a marked protrusion in the left false vocal fold. We performed the laryngeal microsurgery to discriminate the tumorous condition. The pathology revealed non-pathologic mucosa. We report a unique and didactic case with a brief literature review.
