Typical Clinical Scenarios

An adult presents to the emergency department after a dog bite with an avulsed segment of the orbicularis oris muscle causing significant loss of continuity and impaired lip function; the patient is admitted for urgent surgical restoration of muscle continuity to preserve oral competence and facial symmetry. A reattachment procedure is performed under open exposure to reapproximate the separated facial muscle to its normal anatomical location. Typical codes: 0KM10ZZ
An adolescent involved in a motor vehicle collision has partial avulsion of the zygomaticus major muscle with overlying soft tissue lacerations; after initial stabilization and imaging, the patient is taken to the operating room for definitive surgical reattachment of the facial muscle to restore smile function and prevent long-term dysfunction. The procedure is performed via an open approach to access and secure the muscle to its original attachment. Typical codes: 0KM10ZZ
A middle-aged patient returns to the hospital weeks after attempted outpatient repair of a traumatic facial laceration because persistent discontinuity of the levator labii superioris muscle results in asymmetry and functional deficit; inpatient re-exploration and reattachment of the facial muscle to its suitable location is performed to correct the failed initial repair. Typical codes: 0KM10ZZ, 0KM14ZZ
