Hemorrhage secondary to interforaminal implant surgery: anatomical considerations and report of a case.

Understanding the anatomy of the floor of mouth is very important as severe submandibular hemorrhages are life threatening. This case report illustrates the potential hemorrhage consequences of implant surgery within the interforaminal region. The highly vascularized interforaminal region is susceptible to hemorrhage, which can be induced simply by instruments causing vascular trauma. The risk of intraoperative bleeding can be minimized by painstaking preoperative clinical and radiological examination but cannot be averted as it is inherent in the underlying anatomy of the region.
