ENT Trauma Physical Examination Findings
Critical Initial Assessment
Before any facial examination, ensure airway, breathing, and circulation (ABC) are stabilized, as maxillofacial trauma can cause airway compromise through hemorrhage, soft-tissue edema, and loss of facial architecture from fractures. 1
Systematic Physical Examination Components
Inspection and Palpation
- Palpate all facial bones systematically for step-offs and crepitus, which indicate underlying fractures 1
- Assess for facial asymmetry, deformity, and lacerations through visual inspection 1
- Examine for tenderness to palpation, contusion, or edema over the frontal bone, which suggests frontal bone injury 2
- Evaluate for pain with upper jaw manipulation, pain overlying zygoma, facial elongation, or zygomatic deformity, all indicating midface injury 2, 1
Neurological Assessment
- Test infraorbital nerve sensation, as paresthesia suggests midface injury involving the zygomaticomaxillary complex 2, 1
- Perform complete cranial nerve evaluation to detect nerve injury from facial trauma 1
Ophthalmologic Examination
- Conduct full visual acuity testing and extraocular movement assessment in all patients with facial trauma 1
- Ophthalmology consultation is mandatory for all orbital fractures to assess visual acuity, extraocular movements, and globe integrity 1
Dental and Occlusion Assessment
- Evaluate dental occlusion to detect maxillary or mandibular fractures 1
- Assess for malocclusion, which strongly suggests midface injury 2, 1
Cerebrospinal Fluid Leak Detection
- Examine for cerebrospinal fluid leak through nasal or aural drainage, particularly with frontal bone or skull base fractures 1
Cervical Spine Evaluation
- Cervical spine clearance is essential before any facial manipulation, as 11% of mandibular fracture patients and 7-19% of patients with significant maxillofacial trauma have concomitant cervical spine injury 2, 1
Specific Injury Patterns and Associated Findings
Frontal Bone Injuries
- Tenderness to palpation, contusion, or edema over the frontal bone are the primary clinical indicators 2
- Displaced posterior table fractures may indicate underlying dural disruption 3
Midface Injuries
- Pain with upper jaw manipulation combined with infraorbital nerve paresthesia has high specificity for zygomaticomaxillary complex fractures 2
- Facial elongation suggests maxillary fracture (Le Fort patterns) 2
- Periorbital ecchymosis, enophthalmos, and facial asymmetry indicate severe maxillary injuries 2
Vascular Injury Signs
- Vascular soft signs were present in 57% of penetrating neck injury patients and require systematic assessment 4
- Complex skull fractures or scalp degloving are risk factors for blunt cerebrovascular injury (BCVI), which carries significant morbidity and mortality if missed 2
Critical Pitfalls to Avoid
- Never manipulate the cervical spine before clearance, as the incidence of concomitant cervical spine fractures is 11.3% in patients with maxillofacial injuries 2
- Do not rely on physical examination alone to rule out significant injury, as 68% of facial fracture patients have concomitant intracranial injury requiring CT imaging 1
- Recognize that the absence of soft signs does not exclude injury in penetrating trauma, though the negative predictive value is 98.7% 4
