Colgajo de avance miomucoso del bermellón para la reconstrucción de defectos superficiales del labio

Área de la Ciencia:

• Plastic Surgery
• Reconstructive Surgery
• Oral and Maxillofacial Surgery

Sus antecedentes:

• Reconstructing vermilion (lip border) defects presents challenges in restoring appearance, function, and sensation.
• The vermilion myomucosal advancement flap utilizes adjacent native tissue for reconstruction.
• This study assesses the efficacy of this flap for full-thickness vermilion defects.

Objetivo del estudio:

• To evaluate the outcomes of vermilion myomucosal advancement flaps in reconstructing full-thickness lip defects.
• To assess aesthetic satisfaction, scar quality, and sensory recovery post-surgery.

Principales métodos:

• Retrospective review of 17 patients with vermilion defects (<50% lip width) reconstructed with myomucosal advancement flaps.
• Outcomes assessed at 12 months postoperatively.
• Aesthetic and scar assessments using Visual Analog Scale (VAS) and Patient and Observer Scar Assessment Scale (POSAS); sensory testing via Semmes-Weinstein Monofilament (SWM).

Principales resultados:

• 17 patients (mean age 42.9 years) with average 1.9 cm defects were included.
• High patient (mean VAS 9.24) and observer (mean VAS 8.76) satisfaction reported, with low scar scores.
• Excellent sensory recovery (SWM scores near healthy tissue) and oncologic margins achieved; only one minor complication (dehiscence).

Conclusiones:

• The vermilion myomucosal advancement flap is a safe, reliable, single-stage solution for small to moderate vermilion defects.
• The procedure yields superior aesthetic, functional, and sensory results with minimal morbidity.
• A 2:1 flap-to-defect length ratio is recommended for surgical planning.
