“…Similar to the present study, previous study used a facial artery perforator flap combined with a separate DAO chimeric flap, and they reported satisfaction in all patients 15 . However, the facial artery perforator flap can be used for limited height defects with obvious facial scar formation at the donor site.…”

Additionally, our aesthetic results were satisfactory, with high POSAS scores for both the surgeon and the patients, although not statistically significant between the two groups.…”

“…The DAO flaps play a crucial role in reconstructing sensate lips and functional oral sphincters of normal dimensions without invading or enervating the upper lip and avoiding microstomia in reconstructing large defects 13,14 . In literature, DAO muscle chimeric flap has been described in conjunction with facial artery perforator flaps as a dependable reconstructive option for lower lip defects 15 . However, using DAO muscle as a separate muscle flap to reconstruct oral sphincters has not been widely adopted, and there is a shortage of its functional outcomes.…”

Background Lower lip reconstruction aims to maintain facial subunit function and aesthetics. We present a minor modification of the McGregor flap technique, in which depressor anguli oris (DAO) muscle is separately elevated as a chimeric flap together to investigate the outcomes for reconstructing lower lip defects using various functional parameters. Methods The study included patients who underwent surgical repair of lower lip defects using a McGregor fan flap with or without DAO muscle chimeric flap between January 2018 and May 2021. The patients were divided into our modified technique with DAO chimeric flap (study group) and conventional McGregor (control group). The primary outcomes were functional evaluation of oral competency, speech intelligibility, and tactile sensation of reconstructed lip outcomes. The functional satisfaction and Patient and Observer Scar Assessment Scale (POSAS) were analyzed. Results A total of 20 patients were enrolled (10 patients for each group). Excellent oral competence was present in 12 patients, favorably significant in patients with DAO chimeric flap (n = 8/10, p = 0.018). All patients had intelligible speech with insignificant differences between the two groups. No patients demonstrated differences to light touch from baseline sensation at 1 year. Patients in the study group reported more lip function satisfaction (p = 0.049). The POSAS score indicates satisfaction with the appearance of all patients. Conclusion McGregor fan technique combined with DAO muscle chimeric flap offers a good choice by maintaining sensory and motor functions. Our minor modification can ensure the integrity of the oral sphincter, leading to improved lower lip function.
