Postoperative maxillary cyst is a rare complication of surgical intervention associated with maxillary sinuses. The present paper describes a 25-year-old man presenting with a lump sensation in the left cheek area after Le Fort I osteotomy and mandibular sagittal split osteotomy. The orthopantomograph revealed a bony defect in the left maxillary alveolus. On the computerized tomography, a 1x2x3cm sized, lower density mass, between the left paramedian side of the maxillary alveolar process and hard palate was observed. The cyst was drained and enucleated. More frequent post-operative maxillary cysts may occur with an increase of Le Fort I osteotomies.
