Optimal treatment of midfacial gunshot wounds includes early definitive reconstruction of the bony scaffold to prevent soft tissue contraction. When this is not possible, secondary reconstruction is more difficult. The authors present a case of delayed reconstruction of a midface gunshot wound. Two months following a self-inflicted, submental gunshot wound and eventual rigid fixation of the remaining midfacial bony anatomy, two simultaneous radial forearm free flaps were utilized in the reconstruction. The first flap was folded onto itself to recreate the hard palate in conjunction with a split rib graft; the second flap filled the remaining soft-tissue defect and simultaneously provided lining for an eventual staged nasal reconstruction. The second stage of the nasal reconstruction was completed 5 weeks later with a calvarial bone graft and forehead flap. This dual microsurgical approach allowed for one-step reconstruction of both surfaces of the hard palate, resulting in separate oral and nasal cavities, and optimizing the patient's ability to speak and eat. Extensive soft-tissue contraction encountered in late reconstructions underscores the importance of an early, definitive, surgical approach in these difficult wounds.
面中部枪伤的最佳治疗方法包括早期对骨支架进行确定性重建,以防止软组织挛缩。若无法做到这一点,二期重建会更加困难。作者介绍了一例面中部枪伤延迟重建的病例。在自伤性颏下枪伤并最终对剩余面中部骨骼结构进行坚固固定两个月后,同时使用了两个桡侧前臂游离皮瓣进行重建。第一个皮瓣自身折叠,并结合劈开的肋骨移植来重建硬腭;第二个皮瓣填充剩余的软组织缺损,并同时为最终分阶段进行的鼻重建提供衬里。鼻重建的第二阶段在5周后通过颅骨骨移植和额部皮瓣完成。这种双重显微外科方法允许一步重建硬腭的两个表面,形成独立的口腔和鼻腔,并优化了患者的说话和进食能力。晚期重建中遇到的广泛软组织挛缩凸显了对这些复杂伤口采取早期、确定性手术方法的重要性。
