硬化療法が著効した喉頭血管腫の１例

Abstract

Laryngeal hemangioma is a comparatively rare benign tumor of the larynx. Surgical removal, laser therapy, cryosurgery and sclerotherapy are some of the treatment modalities employed.We report a case of laryngeal hemangioma occurring in the right arytenoid. The patient was a 46-year-old woman complaining of an abnormal sensation in her larynx. The tumor was treated by injecting 5 % ethanolamine oleate, a sclerosing agent which has been used endoscopically in the treatment of esophageal varices through a direct laryngoscope. Two days after the operation, we found a slight edema in the larynx, but it was not necessary to perform a tracheostomy. The tumor had been reduced to a very small one in the right arytenoid one year after the operation. The treatment modality described above has three advantages : there is little bleeding during the operation, almost no scars or organic defects are left after the procedure, and it is easier to perform compared to other surgical treatments. Therefore, we recommend it as a first choice treatment, especially for small laryngeal hemangiomas.
