Idiopathic masseter muscle hypertrophy.

Kebede B, Megersa S - Ethiop J Health Sci (2011)

Bottom Line: In some cases prominent Exostoses at the angle of the mandible are noted.Although it is tempting to point to Malocclusion, Bruxism, clenching, or Temporomandibular joint disorders, the etiology in the majority of cases is unclear.Treatment usually involves resection of a portion of the Masseter muscle with or without the underlying bone.

ABSTRACT
Benign Masseteric Hypertrophy is a relatively uncommon condition that can occur unilaterally or bilaterally. Pain may be a symptom, but most frequently a clinician is consulted for cosmetic reasons. In some cases prominent Exostoses at the angle of the mandible are noted. Although it is tempting to point to Malocclusion, Bruxism, clenching, or Temporomandibular joint disorders, the etiology in the majority of cases is unclear. Diagnosis is based on awareness of the condition, clinical and radiographic findings, and exclusion of more serious Pathology such as Benign and Malignant Parotid Disease, Rhabdomyoma, and Lymphangioma. Treatment usually involves resection of a portion of the Masseter muscle with or without the underlying bone.

Figure 2: Antero-posterior radiograph showing spur development in the left angle of the mandible.

Mentions: An antero-posterior and lateral oblique radiography was taken to rule out unilateral masseter muscle hypertrophy. The finding showed a compensatory hypertrophy in the area of muscle insertion due to the increase of the muscle size and tension. Prominence of the mandible angle and bone spur development was detected (Fig. 2).
