Background:
Reconstruction of the oral cavity commonly results in trismus and lip incompetence.
Aim And Objectives:
In this study, we aim to describe an innovative design of a radial forearm free flap for resurfacing bilateral buccal defects and simultaneous functional lower lip reconstruction in a single stage.
Materials And Methods:
Between January 2010 and December 2019, 6 males underwent simultaneous buccal and lower lip reconstruction with a radial forearm free flap. The mean age of the patients was 57.3 years (range, 50-68 years). The defects were caused by trismus release and due to previous treatments. The mean size of the defects was 17.9 cm in length and 3.25 cm in width. Flaps were harvested, including the proximal perforators of the radial vessels, and the inset began in the buccal area opposite the anastomosis side.
Results:
Flap size ranged from 16 to 21 × 2 to 4 cm. The recipient vessels used were the superficial temporal (4) and facial (2). All flaps survived. Lip infection was seen in 2 cases and managed conservatively. The mean follow-up was 19.2 months (range, 12-28 months). The mean increase in the interincisal distance was 10.7 mm. Oral continence was good in all patients. Speech intelligibility was considered total in 4 patients and partial in the remaining 2.
Conclusion:
The radial forearm flap constitutes an option for simultaneous lower lip reconstruction and resurfacing of bilateral buccal areas after trismus release. The procedure provides a thin and pliable reconstruction using only 1 donor site and 1 set of recipient vessels.
