Background:
The cervicomental angle is a critical anatomical feature in neck aesthetics, and age-related changes can lead to sagging, platysma bands, and loss of definition. Traditional neck rejuvenation techniques focus on tightening the horizontal platysma but often fail to restore the cervicomental angle. This study evaluated a minimally invasive hyoid suspension (MIHS) lift, which anchors the platysma to the prehyoid deep cervical fascia through a limited submental incision.
Methods:
Between October 2023 and July 2024, 6 female patients (mean age, 63.0 y) underwent the MIHS lift alongside face lift and liposuction. The technique involved minimal subcutaneous dissection and direct platysma anchoring to reduce scarring and tissue trauma. The submental incision was limited to approximately 2 cm. Outcomes were assessed using the Knize cervicomental classification and the Gupta platysma band grading. Two surgeons performed all procedures and evaluations.
Results:
Neck contour and the cervicomental angle improved in all patients, with no complications. Preoperatively, 2, 1, and 3 patients were classified as Knize cervicomental class I, II, and III, respectively; postoperatively, all patients achieved class I. Platysma bands resolved in all patients. Submental scarring was minimal and inconspicuous on clinical examination.
Conclusions:
The MIHS lift appears to offer a low-morbidity, natural-appearing option for neck contouring by minimizing invasiveness. Although early outcomes are promising, further validation is needed. This technique may be useful for individuals prone to hypertrophic scarring (eg, Asian patients).
