This report focuses on a potentially fatal hemorrhage arising from dental implant placement in the mandible. Anatomic considerations of the lingual artery and its divisions in the floor of the mouth are discussed. In addition, various methods of controlling bleeding from the floor of the mouth are reviewed. The case presented is unusual in that intraoral ligation of the transected vessel was possible despite the presence of massive sublingual, submental, and submandibular hematomas as well as severely distorted anatomy. This case represents a severe complication resulting from a seemingly minor oral surgical procedure. Those performing endosteal implant placement should be knowledgeable in the management of such complications.
本报告聚焦于下颌骨种植牙植入引发的潜在致命性出血。讨论了舌动脉及其在口腔底部分支的解剖学考量。此外，还回顾了控制口腔底部出血的各种方法。所呈现的病例不同寻常之处在于，尽管存在大量舌下、颏下及颌下血肿以及解剖结构严重扭曲的情况，仍有可能对横断血管进行口内结扎。该病例代表了看似轻微的口腔外科手术引发的严重并发症。进行骨内种植牙植入的人员应熟知此类并发症的处理方法。
