目的 总结通过留“桥”技术形成的细长皮管在鼻小柱再造中的应用。方法 196 8年 3月～ 1998年 8月 ,利用留“桥”技术形成细长皮管 ,分次转移 ,修复复杂鼻小柱缺损共 18例。采用上臂内侧纵行皮管 13例 ,颈部锁骨上横行皮管 5例 ,设计皮管宽度 2 .0～ 2 .5 cm,长度 11～ 15 cm,皮管中段 3～ 7cm于其一侧留“桥”。结果18例皮管均成活 ,无并发症 ,随访 3～ 6 0个月 ,再造鼻小柱外形、质地、色泽、抗损伤能力均良好。结论 为保证细长皮管的血运 ,皮管中段需留“桥”,二期断“桥”。此皮管能提供外形精致、相对丰富的组织 ,在修复鼻小柱缺损 ,特别是合并鼻尖、鼻中隔、鼻翼部分缺损 ,或伴有口鼻周围软组织缺损时 ,可修复多处畸形 ,效果良好。缺点是疗程稍长。
OBJECTIVE: To summarize the application of the thin skin tube formed by the left “bridge” technique in the reconstruction of columella. Methods March 1996 ~ August 1998, the use of left “bridge” technology to form elongated skin tube, graded transfer, repair of complex nasal column defects in 18 cases. Thirteen cases of medial longitudinal arm of upper arm and 5 cases of lateral transverse skin neck of neck were designed. The width of skin tube was designed to be 2.0-2.5 cm and length of 11-15 cm. “bridge”. Results 18 cases of skin were alive, no complications, follow-up of 3 to 60 months, reconstruction of nasal column shape, texture, color, anti-injury ability were good. Conclusion In order to ensure the blood supply of the elongated skin tube, a “bridge” should be left in the middle of the skin tube and the “bridge” should be broken in the second phase. This skin tube can provide exquisite and relatively rich tissue. It can repair multiple deformities and repair well, especially when it is combined with nasal tip, nasal septum, nasal part defect or soft tissue defect around the nose and nose. The disadvantage is the longer course of treatment.
