Background and Objectives
: Benign neoplasms of the larynx are rare, and papillomas account for approximately 90% of these neoplasms. Other benign neoplasms of the larynx are very rare and form a hetergenous group. We present clinical manifestations of unusual benign neoplasms based on our experiences and review of literatures.
Materials and Method
: We reviewed retrospectively the clinical records of 14 patients with benign neoplasms of the larynx, excluding papillomas, that were examined in our department during 11-year period from 1995 to 2006.
: The presenting symptom was most commonly progressive dysphonia. Pathologic diagnosis revealed 5 cases of hemangioma, 3 granular cell tumor, 2 amyloidosis, 2 laryngocele, 1 schwannoma, 1 chondroma. Subsites of the neoplasms were 5 in true vocal cord, 3 in arytenoids, 2 in false vocal cord, 2 in supraglottis, and others were subglottis ; aryepiglottic fold. Treatment was surgical, by a external approach in 1 case of chondroma, and by laryngoscopic approach in other cases. In laryngoscopic approach, carbon dioxide laser was used in 10 cases. Postoperative course was satisfactory. Recurrence was encountered in I case of amyloidosis and revision operation was done 3 times. No recurrence was encountered in other cases.
: Uncommon benign neoplasms of the larynx require high index of suspicion and histological confirmation. Complete excision with an attempt to maintain normal structures generally results in cure.
