Displacement of an impacted maxillary third molar into the infratemporal fossa is frequently mentioned but rarely reported. Imaging and retrieval of such a displaced tooth is difficult and requires urgent referral and hospitalisation for removal under general anaesthetic. The use of image intensification equipment in theatre allows removal of such a displaced tooth with minimal morbidity and is recommended. Prevention of displacement with the use of a distal retractor is strongly recommended when surgically removing impacted maxillary third molars.
上颌第三磨牙阻生并移位至颞下窝的情况虽常被提及，但鲜有报道。此类移位牙的影像学检查及取出操作困难，需要紧急转诊并住院接受全身麻醉下的拔除手术。术中使用影像增强设备可使此类移位牙的拔除创伤降至最低，故推荐使用。在手术拔除上颌阻生第三磨牙时，强烈建议使用远中牵开器以防止移位。
