An alternative procedure for conjunctivodacryocystorhinostomy - Supratrochlear artery-based island flap combined with buccal mucosal graft

Reconstruction of the total canalicular obstruction with destroyed medial canthal area is a challenging procedure for ophthalmic, plastic, and reconstructive surgeons. In the case presented, a supratrochlear artery-based island flap combined with a buccal mucosal graft was used for reconstruction of the medial canthal area. The medial canthal area was scarred significantly and demonstrated a medial ectropion and complete canalicular obstruction. To our knowledge, it is the first time for combined reconstruction of the medial canthal area and lacrimal drainage system in 1 stage, with island median forehead flap based on supratrochlear artery and buccal mucosal graft. During the 2-year follow-up period, no complication was encountered and the patient healed uneventfully.
