Acute dissecting hematoma: a complication of oral and maxillofacial surgery.

The ADH is an uncommon but potentially life-threatening bleeding complication after oral maxillofacial surgery. Prevention via adequate preoperative laboratory evaluation and meticulous mechanical hemostasis during surgery is important. In spite of these measures, cases will infrequently occur, necessitating rapid accurate diagnosis and effective therapy. Close monitoring and continual airway assessment and control are paramount. Local measures are usually effective in hemorrhage control and the use of prophylactic antibiotics is suggested.
