하마종 치료에서 설하선 절제의 필요성： 예비연구

Background and Objectives: Most ranulas develop as a result of salivary extravasation from the sublingual gland. Several treatment modalities have been reported, but the optimal is still controversial. We analyzed the effectiveness and potential risks of currently available surgical treatment modalities for ranula to determine one that was optimal. Materials and Methods: Sixty-four patients with ranulas underwent surgical procedures which included incision and drainage, marsupialization, ranula excision, and excision of sublingual gland with ranula. Recurrence and related complications were documented. Results: The recurrence rates of incision and drainage, marsupialization, ranula excision, excision of the sublingual gland with ranula were 100%, 35.7%, 18.8%, and 3.4%, respectively. The patients who underwent excision of the sublingual gland with ranula had minimal complications and recovered without any problems. There is no significant difference of recurrence rate accoding to the type of ranula. Conclusion: The surgical methods were more important factor than the types of ranula in the recurrence. Excision of sublingual gland with ranula should be considered in choosing the primary surgical treatment modality in any type of ranula. (J Clinical Otolaryngol 2010;21:61–66)
