안와주위 봉와직염을 초래한 함치성 낭종 1례

Dentigerous cysts are rare developmental anomalies in maxillary sinus which arise from accumulation of fluid between the reduced enamel epithelium and tooth crown in associated with unerupted tooth. These are often asymptomatic and detected incidentally on routine radiographs for screening purpose. Occasionally, they can be large and cause symptoms related to expansion and impingement on contiguous structures. The potentiality to become ameloblastomas, epidermoid carcinomas, or mucoepidermoid carcinomas has been pointed frequently. Therefore, proper diagnosis and treatment are recommended.

Recently, the authors have experienced a case of dentigerous cyst in the right maxillary sinus resulting in periorbital cellulitis. This cyst was removed successfully by enucleation through the Caldwell Luc's approach.
