Background

  • Consists of 4 contiguous potential spaces bounded by the muscles of mastication:
    • Masseteric, superficial temporal, deep temporal, pterygomandibular
  • Bacteria gain entry to the space from[1]:
    • Odontogenic (tooth extractions, periodontitis, pericoronitis, dental caries, pulpitis, etc) - most common source
    • Trauma (e.g. to the TMJ)
    • Surgery
    • Injections (e.g. inferior alveolar block)
  • Spaces communicate with the tissue planes that extend down the neck to the mediastinum

Clinical Features

  • Initial symptoms are similar to TMJ disease
  • Trismus
  • Tenderness to muscles of mastication
  • Facial swelling and erythema
  • Fever, malaise, dysphagia

Differential Diagnosis

Facial Swelling

Evaluation

  • CT of facial bones with IV contrast

Management

  • Clindamycin IV
  • Consult ENT for surgical drainage of abscess

Disposition

  • Admit
