Abstract
The purpose of this study was to determine the incidence of and reasons for unplanned reoperations in oral and maxillofacial surgery. During a 4-year period, a total of 169 patients undergoing reoperations were encountered. The clinical characteristics and causes were reviewed. There were 11,151 patients who underwent surgery, and the incidence of unplanned reoperations was 1.52%. The male-to-female ratio was 2.45:1. The average age in this cohort was 51.5years. Among the common causes of an unplanned return to the operating room, the most common were reoperations performed for postoperative bleeding, diagnostic issues, and vascular crisis (32.54%, 28.40%, and 29.59%, respectively). The unplanned reoperation rate was 1.52%. The main causes were postoperative bleeding, diagnostic issues, and vascular crisis. Patients with malignant tumors or microvascular flaps were more likely to undergo unplanned reoperations. Improving perioperative management and diagnostic capability might reduce the incidence of unplanned reoperations.
