OK-432 sclerotherapy in head and neck lymphangiomas: long-term follow-up result.

INTRODUCTION Nonsurgical treatments, such as sclerotherapy have been attempted for head and neck lymphagiomas. Of the available sclerosing agents, picibanil has shown satisfactory short-term treatment results in many studies, but no study has presented long-term treatment results. Accordingly, in the present study, the authors retrospectively reviewed the long-term treatment results of picibanil sclerotherapy. MATERIALS AND METHODS Fifty-five lymphangioma patients who underwent picibanil sclerotherapy were enrolled. Data about initial and long-term response, recurrence, and excision rate were collected. RESULTS Initial response rates were 83.5 percent and long-term response rates were 76.3 percent. CONCLUSION Initial and the long-term response rate were equally good for lymphangioma.
