Deep subcutaneous cervical emphysema related to mastoid fracture in an adolescent patient - case report
Abstract: A fracture of the mastoid bone should be considered in the work-up of a head and neck traumatic injury. A well-pneumatized mastoid can absorb forceful impacts, protecting middle and inner ear structures. Fractures of the mastoid, followed by Valsalva maneuver can lead to subcutaneous cervical emphysema.
