[Reconstruction with pyriform sinus mucosa in partial laryngectomy].

OBJECTIVE: To assess the effectiveness of reconstruction with pyriform sinus mucosa in partial laryngectomy and resumed laryngeal function. METHOD: A total of 198 cases of laryngeal cancer who had undergone partial laryngectomy from 1980 to 1995 in our hospital were retrospectively reviewed. Defect of larynx were repaired with pyriform sinus mucosa in all cases. Surgery of local lesions: 87 cases underwent supraglottic horizontal partial laryngectomy, 65 vertical or extended vertical partial laryngectomy, 46 horizontal vertical partial laryngectomy. RESULT: In cases underwent supraglottic horizontal partial laryngectomy, postoperative decannulation rate is 100%, 5 year survival rate is 84.70% and functions of voice, respiration and deglutition were all preserved well. In cases underwent vertical or extended vertical partial laryngectomy, decannulation rate is 87.67% and 5 year survival rate is 86.15%. Functions of respiration and deglutition are good but existent hoarseness. In the earlier stage after operation, there was serious aspiration in the cases underwent horizontal vertical laryngectomy and it took patients more time to overcome aspiration by practice. In this group, decannulation rate is 82.60% and 5 year survival rate is 78.26%. all cases present hoarseness and part of them can't be extubated because of glottic stenosis. CONCLUSION: The authors believe that this method of surgery is safe and beneficial to some patients with partial laryngectomy. Laryngeal functions can be well preserved with this technique.
