摘要
A median palatal cyst is an uncommon nonodontogenic cyst, and patients usually present with a painless swelling or the sen-sation of a mass. The mass is typically a well-defined fixed swelling along the midline. The mass can cause slight elevation of the nasal floor or swelling and drainage from the hard palate. Surgical resection is usually recommended as a definite treatment.
We treated a 30-year-old man with a premaxillary mass with nasal obstruction. He had undergone surgery on both the maxilla and the mandible to correct malocclusion 10 years earlier. A physical examination revealed elevated mucosa of the nasal floor, resulting in near-total obstruction of the nasal cavity, and the gingival mucosa over the upper incisors was also swollen. Preoperative computed tomographic scan demonstrated a midline nonenhancing round cystic lesion in the premaxillary area. Surgical excision was performed via a sublabial approach under general anesthesia, and his recovery after surgery was uneventful.
