Commissurorraphy in the Dog

Commissurorraphy is a surgical procedure designed to move the lip commissure rostrally. This procedure may be helpful as a unilateral procedure in cases of unilateral mandibulectomy to support tongue function and improve esthetics. Bilateral commissurorraphy is utilized in cases of radical bilateral mandibulectomy and as a salvage procedure for support of bilateral mandibular fractures in cases where rigid surgical fixation is not feasible. Dehiscence is the most likely complication of commissurorraphy. Tension can be reduced at the rostral extent of the incision by utilizing mattress sutures, intravenous fluid tubing, and/or buttons to prevent tearing through sutures.
