Background: The reported incidence of hematoma following male rhytidectomy ranges from 7.9 to 12.9 percent. In 1976, it was demonstrated that postoperative hypertension is a key etiologic factor in hematoma formation and postoperative use of Thorazine was recommended to control blood pressure. This study analyzes the incidence of hematoma after male rhytidectomy at one institution after a strict and aggressive perioperative blood pressure control regimen was iniated. Methods: From 1.982 to 2002, 985 patients with a mean age of 61 years (range, 49 to 72),ears) underwent rhytidectomy. Thirty-six patients required surgical evacuation of expanding hematoma after rhytidectomy. Operative procedures were performed by more than 100 different plastic surgery attending surgeons, residents, and fellows. Results: The overall incidence of hematoma during this study period was 4.24 percent. Age, medical history, medications, style of anesthesia, rhyddectomy technique and combination of-procedures, and length of operation were not independent risk factors for determining who was more likely to develop a hematoma. Thirty-three percent of the patients requiring Surgical evacuation had systolic blood pressure greater than 150 mmHg and diastolic blood pressure greater than 90 mmHg preoperatively, intraoperatively, and postoperatively. Over a 30-year period, the incidence of hematoma requiring surgical evacuation has decreased From 8.7 percent to 3.97 percent after initiation of-a strict perioperative blood pressure control regimen. Conclusion: Despite the lower incidence of hematoma following male rhytidectomy today as compared with 30 years ago, the incidence in men (3.97 percent) remains higher than that in women (I to 3 percent).
