Microsurgical Reconstruction of Extensive Lower Lip Defects: An Algorithm for Free Flap Selection and Functional Outcomes.

[BACKGROUND] Large defects of the lower lip pose a difficult challenge for any reconstructive surgeon. When there is limited local tissue available to resurface the defects, free flaps are the preferred option.

[AIM AND OBJECTIVES] We reported our experience in the reconstruction of extensive lower lip defects. The authors propose a new algorithm for microsurgical technique selection and assessment of the functional outcomes obtained.

[MATERIALS AND METHODS] A retrospective review of all microsurgical reconstructions of extensive lower lip defects by the senior author for 10 years was performed. The functional outcomes assessed included speech, feeding, and oral continence. Patients were stratified according to their status of simultaneous mandible resection (none, marginal, segmental).

[RESULTS] Fifty-one patients were included in this study. Almost all patients (96.1%) achieved intelligible speech. Only 1 patient experienced severe drooling. Most patients could eat a solid or soft diet (72.5%). Mandible resection was associated with the worst feeding outcomes.

[CONCLUSIONS] Microsurgical reconstruction of extensive lip defects is safe and provides good results. Free flap selection should take into account the location of the defect, the resected structures, and the body mass index of the patient. Feeding status seems to be inversely correlated with the amount of mandibular resection.
