The Use of a Nasolabial Island Flap in Vestibulo-sulcoplasty in a Patient with Recurrent Depressed Scar on the Modiolus

A 56-year-old woman with a recurrent depressed scar of the commissure, treated with a nasolabial island flap, is presented. On examination, the scar was located on the right modiolus involving the right upper gingivobuccal sulcus. A history of recurrent canine abscess was obtained. After excision of the scar and release of the vestibular fold, reconstruction of the defect was performed with a nasolabial island flap from the same side. The postoperative course was uneventful, with a good aesthetic and functional outcome.
