[The use of bi-pedical rotatory door muscle-skin flap reconstruction in extended partial laryngectomy for late (T3 and T4) glottic cancer].

The purpose is to radical treatment for late glottic cancer by surgery, to restore the essential function of the larynx, 62 patients of late (T3 and T4) glottic cancer were treated by extended vertical partial and subtotal laryngectomy. At the same time, an appropriate method of reconstruction of laryngeal function by bi-pedical rotatory door muscle-skin flap was presented. The decannulation rate was 87.1% and 85.0% cases enjoyed satisfactory voice. All cases resumed normal mouth-food-taking. The conclusion is that selective treated with extended partial laryngectomy is effective for T3 and T4 glottic cancer.
