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.
