Trauma to the external ear, can result in a hematoma, a wound to an outline or a fracture. Subperichondrale hematoma (cauliflower ear) The perichondrium supplies blood to the ear cartilage. A blunt outer ear trauma can trigger a subperichondrales hematoma. The accumulation of large amounts of blood between the perichondrium and the cartilage can interrupt the blood supply to the cartilage and turns around the outer ear or part of a shapeless, reddish-livid mass. Avascular necrosis of the cartilage can follow. The subsequent destruction leads to the typical in boxers and wrestlers cauliflower ear. The treatment consists in the immediate removal of the blood clot by incision and prevention of relapse by a continuous seam about a dental cotton roll or by conditioning a Penrose drain, and an additional pressure bandage. Because these injuries for infection and abscess formation tend (500 mg 3 times daily, for. Example, cephalexin) over five days a starling effective antibiotic given. Tips and risks if we fail to make a subperichondriales hematoma drain, which can lead to permanent auricular deformities. Lacerations With injuries of the external ear are sewn the skin edges whenever possible. When the cartilage is penetrated, it will be repaired unless it is not enough skin available to cover the crack. Damaged cartilage whether repaired or not, splinted externally with benzoin-impregnated cotton and protected with a bandage. Haematomas oral antibiotics will be given. Human bite wounds are at high risk of infection, including a possible infection of the cartilage, a potentially serious complication. The treatment includes a thorough debridement of dead tissue, prophylactic antibiotics (eg, amoxicillin / clavulanic acid 500 to 875 mg po 2 times daily for 3 days.) And possibly antivirals (see table: bites of humans or mammals: Antimicrobial drugs). Wounds that h <12 old can be closed, but older wounds should be allowed secondary to heal. Any cosmetic deformities are then treated later. A complete breaks or a partial demolition is supplied by an ENT specialist or a plastic surgeon. Trauma as a result of mandibular fractures severity blows against the lower jaw can be transferred to the front wall of the auditory canal (posterior wall of the glenoid fossa). Displaced fragments of a fractured front wall can lead to stenosis of the channel and need to be surgically reduced or removed in general anesthesia.
