暂无{Abstract}: <B>UNASSIGNED: </B>Primary explosion injuries with fireworks can lead to devastating and geometrically complex facial traumas that present a challenge to the reconstructive surgeon. Our patient, a woman in her early thirties, was hit directly in her chin by a large artillery shell firework. This caused complete soft tissue loss of the lower lip and chin beyond the oral commissures, complicated further by a comminuted mandible fracture.<BR><B>UNASSIGNED: </B>After external fixation, our patient underwent a 2-stage reconstruction with a novel composite flap arrangement. Soft tissue coverage and lip reconstruction were performed with opposing bilateral radial forearm free flaps. The outer flap constituted the soft tissue of the new chin and outer lower lip, whereas the inner flap composed the intraoral lining. In the second stage, portions of the inner upper lip mucosa and superior orbicularis oris muscle were flipped down as a bipedicle, axial pattern "bucket-handle" type flap to the lower lip to reconstruct the vermilion. A graft of fascia lata was attached to the modioli of the orbicularis oris and interpositioned beneath the vermilion flap and the radial forearms to restore static and some dynamic sphincter control. One month later, the mandibular fractures underwent open reduction and internal fixation.<BR><B>UNASSIGNED: </B>Two months after soft tissue reconstruction with no complications, our patient had satisfactory aesthetic outcomes, oral competence, and speech.<BR><B>UNASSIGNED: </B>This case has shown that use of bilateral, fascia lata-reinforced radial forearm flaps may be an effective choice for soft tissue reconstruction and oral competence restoration in cases of severe facial explosion trauma.
