Facial Harmony Restored: Botulinum Toxin in the Management of Masseteric Hypertrophy - A Case Study

Abstract

Masseter muscle hypertrophy (MMH) is a benign enlargement of the masseter muscle, often resulting in a square-shaped facial appearance and potential temporo mandibular joint(TMJ) disorders. This case report highlights a 45-year-old Female presenting with TMJ pain, teeth clenching, and snoring Clinical examination revealed bilateral masseter hypertrophy, classified as Type II, prompting a non-surgical treatment approach using botulinum toxin-A (Botox).

A six-point injection technique was employed for even toxin distribution, resulting in significant muscle volume reduction and improved facial aesthetics after six months. Additionally, a snoring device was prescribed, successfully reducing snoring and enhancing sleep quality. This report emphasizes the efficacy of the six-point Botox injection technique for Masseter muscle hypertrophy and underscores the need for standardizing this protocol through further research.
