Abstract

Purpose

The purpose of this study is to determine the incidence and reasons for unplanned reoperation in oral and maxillofacial surgery.

Materials and Methods

During a 4-year period, a total of 169 patients undergoing reoperation were encountered. The clinical characteristics and causes were reviewed.

Results

There were 11,151 patients undergoing surgery, and the incidence of unplanned reoperation was 1.52%. The male-to-female ratio was 2.45:1. The average age in this cohort was 51.5 years. Among the common causes of 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 27.81%, respectively).

Conclusion

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 reoperation. Improving perioperative management and diagnostic capability might reduce the incidence of unplanned reoperation.
