Nasopalatine duct cysts are the most common non-odontogenic cysts in the maxilla, and are conventionally treated through a sublabial or palatine approach. Recently, the endoscopic approach has been used, but experience is extremely limited. We treated a 29-year-old male with nasopalatine duct cyst by endoscopic marsupialization, but paresthesia of the incisor region occurred after surgery. This paresthesia gradually remitted within 6 months. The nasopalatine nerve, which innervates the upper incisor region, enters two lateral canals separately at the nasal floor and exits the central main canal at the palate. Damage to the bilateral nasopalatine nerves might lead to paresthesia, so we recommend careful examination for nerve fibers during endoscopic surgery, especially if fenestration is performed on both sides.
鼻腭管囊肿是上颌骨最常见的非牙源性囊肿，传统上通过唇下或腭部入路进行治疗。近来，内镜入路已被采用，但经验极其有限。我们通过内镜袋形缝合术治疗了一名29岁患有鼻腭管囊肿的男性患者，但术后出现了切牙区感觉异常。这种感觉异常在6个月内逐渐缓解。支配上前牙区的鼻腭神经在鼻底分别进入两条外侧管，并在腭部从中央主管道穿出。双侧鼻腭神经损伤可能导致感觉异常，因此我们建议在内镜手术期间仔细检查神经纤维，尤其是在双侧进行开窗时。
