We report the clinical course of a patient with a rare iatrogenic surgical complication of transposition of the Parotid duct into the maxillary sinus after tooth extraction.
Oroantral fistula occurs most frequently following maxillary molar or premolar extraction. Closure of an oroantral fistula is frequently closed using the buccal mucoperiosteal flap first described by Rehrmann in 1936. Transposition of the Parotid duct is a rare surgical complication of this technique.
Differential diagnosis of nonspecific discharge from the nose should take this rare cause into account as it is a common symptom of this complication. A careful and full patient history and the correlation of nasal secretion with food intake can lead to the diagnosis.
我们报告了一例患者罕见的医源性手术并发症，即腮腺导管在拔牙后错位进入上颌窦。
发生口腔上颌窦瘘最常见于上颌磨牙或前磨牙拔牙后。奥罗安特拉瘘通常使用颊黏膜骨膜瓣闭合，该技术由 Rehrmann 于 1936 年首次描述。腮腺导管错位是该技术罕见的手术并发症。
从鼻腔排出的非特异性分泌物的鉴别诊断应考虑到这种罕见的原因，因为这是这种并发症的常见症状。仔细和全面的病史以及与食物摄入相关的鼻腔分泌物可以帮助诊断。
