自体真皮脂肪复合组织块移植修复鼻背塌陷

目的 探讨自体真皮脂肪复合组织块在鼻背塌陷修复中作为填充材料的可行性、科学性及修复效果.方法 切取自体臀部或腹部真皮脂肪复合组织块（7.0 cm×1.0 cm×1.0 cm）,作为填充材料,对13例鼻背塌陷、鼻形不良者进行修复,酌情配合耳廓软骨加真皮脂肪复合组织块的伞状移植物,重塑鼻背、鼻尖的良好形态.结果 13例鼻背塌陷者,进行鼻背、鼻尖修复后,真皮脂肪复合组织块存活良好,切口均Ⅰ期愈合,且切口痕迹不明显.经1年随访,鼻外形改善、满意.结论 以自体真皮脂肪复合组织块或结合耳廓软骨移植修复鼻背塌陷,效果满意,且取材方便、无排异反应等,患者易于接受.

Application of autologous dermal-fat flap in repair of collapsed nasal dorsum

Objective To investigate the feasibility, rationality and efficacy of the autologous dermal-fat composite tissue used as filling materials in the repair of nasal dorsum collapse.Methods The dermal fat composite tissue block (7.0 cm× 1.0 cm × 1.0 cm) was removed from the buttocks or abdoman as filling materials. 13 cases of nasal dorsum and nasal-shaped misfits were treated by using an umbrella graft of the auricular cartilage plus dermal-fat composite tissue graft to reconstruct natual shape of nasal dorsum and tip. Results The nasal dorsum and tip were repaired in 13 patients with collapsed nasal dorsum. The dermal-fat composite tissue survived well, and the incisions were healed in stage Ⅰ and the incision trace was not obvious. After follow-up for one year, the shape of nose was much satisfactory. Conclusion It is a well-accepted and easy-going procedure to repair collapsed nasal dorsum with autologous dermal-fat or a combination of composite ear cartilage tissue graft, with satisfactory effect and no rejection reactions.
