Iatrogenic tooth displacement is a rare complication during extraction of impacted molars, but displacement of a maxillary third molar into the maxillary sinus, infratemporal fossa, buccal space, pterygomandibular space, and lateral pharyngeal space has been reported. Currently, 6 published reports describe third molar displacement into the lateral pharyngeal space, only 1 of which involved the loss of a maxillary third molar into this area, which occurred after an attempted self-extraction by the patient. There have been no reported cases of iatrogenic displacement of the maxillary third molar during an extraction procedure. This article describes the recovery, under general anesthesia, of a maxillary third molar from the lateral pharyngeal space after an iatrogenic displacement.
医源性牙齿移位是拔除阻生磨牙过程中一种罕见的并发症，但上颌第三磨牙移位至上颌窦、颞下窝、颊间隙、翼下颌间隙和咽旁间隙的情况已有报道。目前，6篇已发表的报告描述了第三磨牙移位至咽旁间隙，其中仅有1例涉及上颌第三磨牙移位至该区域，该病例发生在患者尝试自行拔牙之后。尚无关于拔牙过程中上颌第三磨牙医源性移位的报道。本文描述了1例医源性移位至上颌第三磨牙从咽旁间隙在全身麻醉下的复位情况。
