Paraganglioma of the larynx is an uncommon lesion. To our knowledge, only 12 cases have been reported, in Japan.
We treated a 33-year-old female with a paraganglioma on the larynx. She was complaining of hoarseness for six months. Indirect laryngoscopic examination demonstrated a large submucosal tumor on the right arytenoid. After CT, MRI, angiography and embolization, we resected the tumor by an external approach with tracheotomy under general anesthesia. Paralysis of the right vocal cord occurred post-operatively, but improved after two months. Histological examination demonstrated that the paraganglioma arose from the laryngeal nerve. There has not been any recurrence for 19 months.
Key words :paraganglioma, larynx, external approach
