Window partial laryngectomy for the treatment of stage T2-3 glottic laryngeal carcinoma / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the operative effect and value of window partial laryngectomy for the treatment of stage T2-3 glottic laryngeal carcinoma.</p><p><b>METHODS</b>From Oct. 2000 to Dec. 2006, the stage T2-3 glottic laryngeal carcinoma of 48 patients by properly selected were performed with window partial laryngectomy and laryngeal reconstruction. Twenty nine males and 19 females were included. Their ages ranged from 43 to 78 years (median 57.0 years). Before operation and in the 6 months after operation, these targets including auditory mental evaluation of hoarse degree, active degree and symmetry of vocal cord, glottic width in the time of quiet breathing, glottic closing degree in the time of phonating, respiratory function and swallowing function were surveyed. In addition, the things of recurrence and metastasis of tumors together with survival time of patients were following investigated.</p><p><b>RESULTS</b>All patients were decannulated successfully and incisions were healed smoothly. No operative complication occurred. Except active degree of vocal cord (P = 0.343), there were respectively significant difference between two group targets of auditory mental evaluation of hoarse degree (all P <0.01), symmetry of vocal cord (P = 0.000), glottic width in the time of quiet breathing (P = 0. 001), glottic closing degree in the time of phonating (P = 0.001) and respiratory function (P=0.001) those were investigated before operation and after operation. The swallowing function wasn't influenced (P= 0.310). There were laryngostenosis in 1 case, recurrence in 1 case (2.1%), cervical lymph node metastasis in 1 case and hepatic metastasis in 1 case. Two cases died. 3-year and 5-year overall survival rate were respectively 96.9% and 88.9%.</p><p><b>CONCLUSIONS</b>The study showed that window partial laryngectomy was successful for treating stage T2-3 glottic laryngeal carcinoma by properly selected. This operation was effective for reducing surgical invasion and beneficial to resume respiratory and vocal function.</p>
