Resection of Bilateral Masseter Hypertrophy and Buccal Fat Pad Associated with Genioplasty to Correct Aesthetic-Functional Disturbances in the Face.

Masseter hypertrophy is an uncommon condition, characterized by an increase in the volume of the masseter region, with the patient presenting functional and aesthetic complaints. Several therapeutic modalities have been suggested for this condition, however, a surgical approach usually presents consistent results in more complex cases. The objective of this article is to report a clinical case of masseter hypertrophy associated with class IV of Kin, treated through partial removal of the masseter muscle, bichectomy and genioplasty. Surgery was performed under general anesthesia in a hospital setting. The planning was previously carried out through prototyped models and radiographs to remove the excess bone shown in the mandibular angle region. Surgical treatment of masseter hypertrophy is effective and long-lasting in severe cases. Additional surgical procedures must be performed in order to provide the best possible result according to the facial deformity found. © The Association of Oral and Maxillofacial Surgeons of India 2022.
