Superficial Temporal Artery Posterior Branch Flap for Reconstruction of Composite Oral/Perioral Defects.

Purpose: Defects involving total lower and/or upper lip often extend to intraoral and/or perioral areas. Flaps based on superficial temporal artery, either as pedicled or free flaps, can be used for reconstruction of various head and neck defects. In this clinical study, we tried to demonstrate the application of a pedicled flap based on the posterior branch of superficial temporal artery in 3-dimensional reconstruction of these composite oral/perioral defects as a successful alternative in cases where microvascular tissue transfer cannot be performed.

Patients And Methods: Six male patients with composite perioral/oral defects who underwent reconstruction with a pedicled flap based on the posterior branch of the superficial temporal artery between April 2020 and December 2020 were evaluated retrospectively. Demographic data, topographic data of defects, and the dimensions of the flaps were gathered from patient files. All patients required reconstruction after tumor resection.

Results: All flaps survived without any signs of partial or total necrosis. Postoperatively, the patients did not report any oral incompetence or drooling, and they were able to fully close their mouths.

Conclusions: Pedicled flaps based on the posterior branch of superficial temporal artery provide reliable results in composite perioral/oral reconstruction.
