골성형 피판을 이용한 치성골종 제거 1례

Once, C-L operation was a fundmental treatment of chronic maxillary sinusitis. However nowadays, the effectiveness of the operation has decreased because of some problems such as facial asymmetry, numbness, and tenderness. Functional endoscopic sinus surgery has substituted the procedure, but still the C-L operation is useful for some diseases. The problems were caused by the removal of mucosa and the bony wall of the sinus. To prevent such complications, the authors gave C-L operation to a patient through the osteoplastic technique. The procedure has been performed on dentogenous osteoma patient. Anterior bony wall of maxillary sinus was incised using the drill, oscillating saw, and osteotome. Then, pathologic lesions in the sinus were completely removed which increased visual field and preserved the sinus mucosa. Finally, the window on the sinus was closed with the bone lid from the original site. The surgical field was good enough to complete removal of the diseases and preserve the sinus mucosa. There were no complications and recurrence. We suggest that the osteoplastic technique is needed in certain diseases which C-L operation would provide to give better visual fields and less opportunity of complications.
