内視鏡下歯根嚢胞切除術の一症例

抄録

The radicular cyst is the most common form of odontogenic cyst. We report on the first case of a large radicular cyst, successfully and radically treated with endoscopic sinus surgery (ESS). The most important points in the surgery for radicular cysts are complete removal of the cyst and treatment of the causative tooth. To meet these criteria, the cyst wall was totally extirpated via the inferior meatal approach and the canine fossa approach. After removal of the cyst wall, the root of the causative tooth was resected with a diamond cutting instrument. This approach has been widely adopted for the surgery of maxillary sinus disease, and is therefore a simple technique for oto-rhino-laryngologists. The ESS technique is very useful in cases of a large radicular cyst extending to the maxillary sinus because it is less invasive for the patient than a conventional approach.
