The extraction of retained and completely impacted third molars is one of the most common surgical procedures performed by dental practitioners with low rates of complications. The accidental displacement during the surgeries of the maxillary third molar into adjacent anatomical spaces is one of the most critical problems that can arise. The most common sites of migration during surgical interventions are the infratemporal fossa, the pterygomandibular space, the maxillary sinus, the buccal space, and the lateral pharyngeal space. In this paper, two cases in which a maxillary third molar accidentally was displaced into the buccal space are presented, the retrieval of the tooth via intra-oral approach is explained, and the anatomical spaces implications are discussed.
拔除阻生及完全埋伏的第三磨牙是牙科医生最常进行的外科手术之一，并发症发生率较低。上颌第三磨牙手术过程中意外移位至相邻解剖间隙是可能出现的最关键问题之一。手术干预期间最常见的移位部位是颞下窝、翼下颌间隙、上颌窦、颊间隙和咽旁间隙。本文介绍了两例上颌第三磨牙意外移位至颊间隙的病例，解释了经口内途径取出牙齿的方法，并讨论了解剖间隙的影响。
