Abstract
PURPOSE: The purpose of this study was to compare primary and secondary wound closure with a buccal mucosal-advancement flap technique on the postoperative course after mandibular impacted third molar surgery. METHODS: The study was conducted on 150 patients who required surgical removal of impacted mandibular third molars under local anesthesia. The study subjects were divided into three groups of 50 patients each, based on the type of closure over the third molar socket. Patients in group I underwent primary closure of the socket with hermetic suturing of the flap, including the vertical release. In group II, a secondary closure was performed, leaving the socket communicating with the oral cavity. In group III, a buccal mucosal-advancement flap technique was employed to achieve primary closure of the flap over the socket while leaving the anterior vertical release, generously patent. All the patients were assessed for pain using the visual analogue scale (VAS), swelling, and mouth opening at postoperative intervals of 2, 4, and 7 days. The wound healing was assessed on day 7. RESULTS: Patients in the buccal mucosal-advancement flap group had significantly less pain and swelling and increased mouth opening compared with primary and secondary closure. Wound dehiscence was seen in 18 patients and alveolar osteitis in 4 patients in primary closure. Delayed wound healing with food accumulation was seen in 6 patients in secondary closure. No complications of flap dehiscence or breakdown were observed in the buccal mucosal-advancement flap group. CONCLUSION: This study concludes that the buccal mucosal-advancement flap technique was a superior closure technique with less pain, swelling, trismus, and satisfactory wound healing compared with both primary and secondary closure after mandibular third molar surgery.
