Mentalis Muscle Reconstruction: An Innovative Technique.

ABSTRACT

BACKGROUND: The mentalis muscle is a significant component of the lower lip; its injury could impair appearance and function. This study presents a surgical strategy for treating mentalis muscle rupture to restore muscle tension and improve function. METHODS: Medical records and photographs of 2 patients with mentalis muscle rupture were reviewed. After physical examinations, 3-dimensional computed topographies were conducted to evaluate chin appearance further. The surgical strategy was designed according to individual malformations and requests. RESULTS: Both patients injured their mentalis muscles in childhood and presented to our clinic with a concave deformity at the center of the chin and impaired mentalis muscle function. The surgical procedure involved the reconstruction of the mentalis muscle by reassembling the muscle flaps and releasing the scarred soft tissue. Both patients were satisfied with the outcome. CONCLUSIONS: Mentalis muscle rupture requires surgical correction. The study proposes an innovative approach that enables patients to achieve a more harmonious appearance and improve function.
