声门癌T_3病变术后的修复

Reconstruction of larynx with epiglottis and strip muscular flap after extended partial laryngectomy with T_3 category

为完善Ｔ３喉癌术后功能保全的方法，将会厌下拉与残留甲状软骨板及环状软骨构成新喉软骨支架，双侧带状肌肌瓣修复术腔创面，形成声门的扩约作用。共行４０例。结果：重建的新喉发音清晰易辩，进食无明显呛咳，功能满意。３年生存率８２．５％（３２／４０），５年生存率７２．９％（２７／３７）。结论：会厌软骨及双侧带状肌瓣与喉为同一术野，血运良好，易于成活，可修复范围广泛，为理想的喉修复材料。

Fourty patients with T_3 glottic cancer were treated by extended partial laryngectomy with reservation of epiglottis and posterior part of thyroid cartilage. The operative defect was covered by bilateral strip muscular flap to reconstruct the sphincter function of the glottis. The 3-year survival rate was 82.5% (32/40)and 5-year survival rate 72.9%(27/37). The function of the reconstructed laryngx was satisfactory. The authors believe that the strip muscular flap is a good material for the reconstruction of the new laryngx because of its good blood supply and widerange repairing capability.
