Surgical removal of the mandibular third molars is one of the most common procedures performed by dentists, as well as by oral and maxillofacial surgeons. Accidental displacement of teeth or roots into the fascial spaces, during surgical removal of the mandibular third molars, is a rare, but serious complication. Herein, we present 2 cases of iatrogenically displaced mandibular third molar roots into the sublingual space, which were successfully removed under local anesthesia intraorally. In addition to methods to minimize the risk of accidental tooth or root displacement, the importance of recognizing this complication and the methods of retrieval are also discussed.
下颌第三磨牙的外科拔除是牙医以及口腔颌面外科医生最常进行的手术之一。在拔除下颌第三磨牙的手术过程中,牙齿或牙根意外移位至筋膜间隙是一种罕见但严重的并发症。在此,我们报告2例医源性下颌第三磨牙牙根移位至舌下间隙的病例,均在局部麻醉下经口成功取出。除了尽量降低牙齿或牙根意外移位风险的方法外,还讨论了识别这种并发症的重要性及取出方法。
