2. Externalear trauma The external ear, consisting of the auricle and external auditory canal (EAC), is generally more vulnerable to physical trauma. The auricle is very vulnerable to both blunt and sharp trauma.
3. The most common complication from blunt trauma to the ear is the formation of auricular hematoma. Failureto recognize and treat this condition early usually leads to an ugly deformity of the pinna known as a “cauliflower” ear.
12. Longitudinal fractures 80% of Temporal Bone Fractures Lateral Forces along the petrosquamous suture line 15 20% Facial Nerve involvement 15- EAC laceration
13. Transverse fractures 20% of Temporal Bone Fractures Forces in the Antero - Posterior direction 50% Facial Nerve Involvement EAC intact
14. Penetrating Trauma Increase in violence and firearms Associated with more dismal outcome More likely to involve intracranial lesions
