INTRODUCTION
Laryngeal hemangiomas are relatively rare in the head and neck area. Most infantile laryngeal hemangiomas resolve on their own, but adult laryngeal hemangiomas (ALHs) do not tend to spontaneous resolve. ALHs located on the arytenoids are a special kind of ALH because of the location and the morphological characteristics of the arytenoids. Compared to other laryngeal hemangiomas, the loose connective tissue of the arytenoids can cause the base of ALHs to be more fully exposed. ALHs located on the arytenoids should be treated because food often goes through the arytenoids. A ruptured tumor can induce serious bleeding, causing blood to flow into the respiratory tract; this can result in death. Many methods have been used to treat ALHs. The optimal surgical approach remains controversial. Some authors advise against ALH excision1. However, Steiner and Ambrosch2 state ALHs can be successfully removed if they are pedunculated or limited to specific areas. In this study, we review the results of 29 cases of ALHs located on the arytenoids to evaluate the treatment methods of excision and conventional chemotherapy.
