A small bursa between the masseter muscle and the zygomatic arch or mandibular ramus, reducing friction during masticatory movement. It is more consistently present at the zygomatic arch attachment than at the mandibular insertion.
Masseter bursitis is an uncommon cause of facial pain and jaw swelling, occasionally coexisting with masseteric hypertrophy in bruxists. It presents as lateral facial swelling over the ramus that is exacerbated by chewing. MRI differentiates it from a parotid mass, masseter tumour, or mandibular pathology. Botulinum toxin injection into the masseter simultaneously addresses bruxism and associated bursitis.
Bursal inflammation at the zygomatic arch producing lateral facial swelling and jaw pain with chewing, associated with bruxism and masseter hypertrophy, treated with activity modification and botulinum toxin.
