[Partial laryngectomy for T3 glottic carcinoma].

OBJECTIVE

To explore the possibility of partial laryngectomy for T3 glottic carcinoma and selection of reconstruction methods.

METHODS

From January 1986 to January 1994, 78 patients with T3 glottic carcinomas were treated by partial laryngectomy. The operative techniques and the reconstruction methods were retrospectively analyzed.

RESULTS

The overall 3 and 5 years survival rates were 88.5% and 75.6% respectively. The local recurrence rate was 15.4%. The reconstruction methods for laryngeal defect repariring following partial laryngectomy were the use of pyriform sinus mucosa with thyroid perichondrium, epiglottic cartilage and bi-pedicaled and bi-muscular flap of strap muscle. The function of respiration, phonation and deglutition recovered well.

CONCLUSION

The partial laryngectomy is suitable for T3 glottic carcinoma. The selection of reconstruction method is based on the size of laryngeal defect.
