A Case of Cavernous Hemangioma of Hypopharynx Treated by Holmium YAG Laser

Abstract

Superficial hypopharynx hemangioma is generally treated by KTP laser, however, we used Holmium YAG laser in this case. Hemangioma was located at the pirif orm sinus. We have performed laser treatment on the surrounding normal tissue of the hemangioma and completely excised it without tracheotomy and with less bleeding. In comparison to Holmium YAG laser and other types (KTP or NdYAG) of laser, Holmium YAG laser is reported to be less damage to neighbor tissues. This case appeared to get good course and laryngeal edema was not observed through the admission. The indication of using Holmium YAG laser treatment is considered to depend on the size of tumor, diameter smaller than 2cm, and to be situated superficial The authors considered the effectiveness of Holmium YAG laser.
