両側原発性上顎洞嚢胞例

Abstract

A rare case of primary bilateral maxillary cysts was reported. The patient was 46 year-old male, whose chief complaint was nasal obstruction. The case was diagnosed as primary bilateral maxillary cyst, on the basis of CT and MRI findings. The medial bony walls of the sinuses were destroyed. The bilateral maxillary sinuses were subsequently opened to the nasal cavity by endoscopic endonasal sinus surgery, and has been no sign of recurrence to date. Only two cases of primary bilateral maxillary cysts have been reported previously in Japan.
