“…Local oral examination was done to rule out other pathologies (diagnosis by exclusion), and masseteric palpation done at rest and during clench was done to confirm the diagnosis. [ 2 13 ] Later, all possible causes that could cause masseter thickness alteration such as dental caries, parafunctional habits, and occlusal abnormalities were corrected. If the “swelling” persisted even after all nonpharmacological interventions, surgical correction was planned [Figures 1 – 8 ].…”

Introduction: The association of mandibular gonial angle, facial height, and jaw relationship in masseteric hypertrophy (MH) has not been adequately described for the typical Indian population. The aim of this study was to report the gonial angle relationship with facial height parameters in cases diagnosed with bilateral MH and its possible influence on the treatment plan. Materials and Methods: This is a retrospective study based on archival records of bilateral MH cases surgically treated over a 10-year period at the author's center. Patients' records fulfilling inclusion and exclusion criteria were considered for the study. Age, gender, upper anterior facial height (UAFH), lower anterior facial height (LAFH), upper posterior facial height (UPFH), ramus height (also a reflection of the lower posterior facial height), and gonial angle were collected along with the type of bite (open/normal/deep), surgical procedure (debulking with/without bone removal), and concomitant jaw bone corrections (yes/no). These were subjected to statistical analysis using SPSS, and P ≤ 0.05 was taken as statistically significant. Results: Overall, 21 patients formed the study group comprising 9 females and 12 males. Gender influenced the UAFH, LAFH, UPFH, ramus height, and gonial angle significantly. Males had higher values than females. Normal bite had an obtuse gonial angle than the deep bite, and the difference was statistically significant ( P = 0.036). When the gonial angle was acute or square faced, the need for other surgical procedures was high and the difference was statistically significant ( P = 00.048). Discussion and Conclusion: The results are discussed in the light of Indian skeletal anthropometry. The relationship of the gonial angle with facial height parameters in bilateral MH cases in this part of the world is presented.

“…This is of particular significance in women, as increase in their bulk gives rise to a squarish or rectangular facial shape and an outward flaring and broadening of the angle regions, which results in a masculine and unappealing appearance. 2 The problem is further compounded if the enlargement is unilateral, leading to an obvious asymmetry.…”

Facial asymmetry is one of the commonest causes of impaired aesthetics, serving as a strong motivation for patients to seek corrective treatment. Benign masseteric hypertrophy is a well-known, albeit uncommon condition of rather obscure etiology, resulting from unilateral or bilateral increase in volume and bulk of the masseter muscle, that may or may not be accompanied by hyperostosis of the underlying bony angle of the mandible. This report elaborates a modified surgical modality and operative technique that effectively addresses both, the hard as well as soft tissue malformations in the region simultaneously, and is associated with the least incidence of relapse and recurrence of the condition. A 26-year-old woman with severe facial asymmetry resulting from unilateral masseteric hypertrophy was taken up for surgical debulking of the masseter. Surgical resection of one-third of the hypertrophied muscle bulk from its inner or medial aspect, followed by shaving of bony spurs and recontouring of angle of the mandible, was done. The surgical technique described is a definitive, efficacious, and reliable intervention for successful and long-term management of idiopathic masseter muscle hypertrophy that results in an excellent and long-lasting aesthetic outcome.
