Background
- Must distinguish zygomatic arch fracture from Zygomaticomaxillary (tripod) fracture
- Tripod fracture = fracture of zygomatic arch, lateral and inferior orbital rims, and lateral wall of maxillary sinus
Clinical Features
- Flattening of malar eminence
- Ipsilateral eye may appear to tilt due to pulling of lateral canthus
- Trismus (due to masseter spasm or impingement of temporalis muscle or coronoid process)
- Palpate posterior surface of arch for tenderness/loss of space compared to other side
Differential Diagnosis
Maxillofacial Trauma
- Ears
- Nose
- Oral
- Other face
- Zygomatic arch fracture
- Zygomaticomaxillary (tripod) fracture
- Related
Evaluation
- CT Sinus/Face
Management
- Analgesia
- If concomitant sinus fracture, prophylactic antibiotics are indicated (amoxicillin/clavulanate, doxycycline, or clindamycin)
Disposition
- Discharge
- Outpatient plastic surgery follow-up in 1 week
