Free Flap Reconstruction of Recalcitrant Defects in Cleft Palate Patients.

[INTRODUCTION] Defects of the palate can be as a result of oronasal fistula of cleft patients and the ablative surgery of tumors. There are many studies about reconstruction of the defects of plate in the literature and most of them are related to tumor surgery. Despite the use of free flaps in cleft patients being not a new approach, the articles in the literature are very few. The authors describe the experience of oronasal fistula reconstructions with free flaps with a new modification of tensionless inset of the free flap's pedicle.

[PATIENTS AND METHODS] Between 2019 and 2022, 2 males and 1 female, 3 consecutive cleft patients underwent free flap surgery because of recalcitrant palatal defects. One patient had 5 and each of remain had 3 unsuccessful reconstructive attempts previously. The age of patients was ranged from 20 to 23 years old. Radial forearm flap was the option of oral lining reconstruction for all patients. In 2 patients, the flap was modified as a skin tail was linked to the flap for covering the pedicle as tensionless closure.

[RESULTS] There was a mucosal swelling in first patient who underwent classical pedicle inset as mucosal tunneling. In 1 patient there was a spontaneous bleeding from the anterior side of the flap and it stopped without medical interventions, spontaneously. There was no additional complication. All flaps survived without anastomosis problems.

[CONCLUSION] Incision of the mucosa rather than tunneling provides good surgical exposure and bleeding control and modified flap design may be beneficial and reliable for tensionless pedicle inset and covering.
