A median palatal cyst is an uncommon nonodontogenic cyst, and patients usually present with a painless swelling or the sensation 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.
腭正中囊肿是一种罕见的非牙源性囊肿，患者通常表现为无痛性肿胀或肿物感。肿物通常是沿中线边界清晰的固定性肿胀。该肿物可导致鼻底轻度抬高或硬腭肿胀及溢液。通常建议手术切除作为确定性治疗方法。我们治疗了一名30岁男性，其前上颌肿物伴鼻塞。他在10年前曾接受过上颌骨和下颌骨手术以矫正错牙合畸形。体格检查发现鼻底黏膜抬高，导致鼻腔几乎完全阻塞，上前牙区的牙龈黏膜也肿胀。术前计算机断层扫描显示前上颌区中线有一个无强化的圆形囊性病变。在全身麻醉下经唇下入路进行了手术切除，术后恢复顺利。
