Abstract

Objective: To evaluate the results of using thinned anterior lateral thigh free flap with preservation of a fat island around the position of the transverse fascia perforator pedicles into the flap. Subject and method: A cross-sectional descriptive study, clinical intervention without a control group on a group of patients with large soft tissue defects in the maxillofacial region who were treated at Center for Caniofacial and Plastic Surgery, 108 Military Central Hospital from January 2016 to January 2022. Result: A total of 35 thinned anterior lateral thigh free flaps were used for patients who needed to shape soft tissue defects in the neck and face at the Center for Craniofacial and Plastic Surgery, 108 Military Central Hospital. The thinness of the flaps was from 1.3 to 3.5cm, the average was 2.4cm; Flap size from 6 × 18cm to 16 × 25cm, the average was 8.6 × 19cm. The thinness of the flap after thinning was from 0.3 to 0.8cm, the average was 0.5cm; The average time for thinning was 8.7 minutes. There were 31/35 flaps that were completely alive, 2 flaps failed not due to thinning of the flap but due to other causes. Conclusion: The ALT flap can be thinned with a simple technique. The near and long term results of using thinned ALT flap for shaping soft tissue defects in the cervicofacial area reached 88.6% and 86.2% respectively, both functional and aesthetic criteria, the flap dissection was clinically favorable advantages, the technique of thinning the flap is easy, takes less time, is safe in blood supply to the flap, has no difference compared to the anterior outer thigh flap that does not thin.
