颈部重叠埋置皮肤扩张器扩张修复颌面颈部瘢痕

目的 探讨在颈阔肌的浅层重叠埋置皮肤扩张器的皮肤扩张技术在颌面颈部瘢痕挛缩畸形修复中的应用及效果.方法 在颈阔肌浅面的同一剥离腔隙内重叠埋置2个扩张器,按期注水扩张,4～6周后行扩张器Ⅱ期手术.结果 自2004年以来应用这一技术整形修复颌面颈部瘢痕挛缩畸形16例,除1例颈部重叠埋置扩张器患者于晚期出现扩张器外露,及时手术处理后未影响最终手术效果外,其余均取得良好效果.结论 扩张器重叠埋置扩张技术与传统的皮肤扩张术相比,在相同时间内可提供更多的可利用的扩张皮肤,降低了与扩张术有关的并发症的发生率,特别是在颈阔肌浅面的重叠埋置扩张尤为适用于颌面颈部瘢痕的整形修复.

Repairing maxillofacial and neck scar by overlapping tissue expansion of neck

Objective To summarize overlapping tissue expansion of neck without platysma in repairing maxillofacial and neck scar contracture deformity.Methods Two expanders were buried in the same soft tissue pocket superficially to the platysma in an overlapping pattern,water injection were on schedule,and secondary operation was performed after 4 to 6 weeks.Results 16 cases of maxillofacial and neck scar contracture deformities were treated with overlapping tissue expansion of neck without platysma since 2004.Good results were achieved except one case of expander exposure,but the final resuit was good after suitable treatment.Conclusion The overlapping tissue expansion technique can provide much more expanded tissue and reduce complications compared with the traditional expansion technique,especially using overlapping tissue expansion of neck without platysma for repairing the defects at the maxillofacial and cervical region.
