The Anatomical Structure Of Laryngeal Measurement And Early Glottic Cancer Surgery And Efficacy Assessment

Objective: To explore the surgery way for T₁, T₂ glottic carcinoma.Methods: From 1997 to 2003, small partial laryngectomy were performed to 112 patients with T₁, T₂ ( T₁N₀M₀ , T₂N₀M₀ ) glottic carcinoma. Retrospectively reviewed and summarized the surgery approach, the curative results and advantages of the surgery treatment, comparing with the laser surgery and radiotherapy. The dynamic follow-up of the movement of the arytenoid cartilage, the reconstruction of the glottis rimae and the changes of the voice were analyzed. The preoperative and postoperative voice quality was compared with the software of Dr. speech system for windows.Results: All patients were healed in one stage about 6 or 7 days and took food with mouth postoperatively 2 or 3 days, and the trachea cannula was removed successfully during the days in hospital. The mean time of all patients with cannula was 7.3 days and the rate of removing the trachea cannula was 100 %. The movement of the arytenoid cartilage of 47 cases 1 week after surgery were weakened, the reconstructed glottis rimae was close to be normal after 6 months postoperatively. There was no significant difference in Shimmer and NNE between preoperative and postoperative 1 week( P > 0. 05), but there was significant differencebefore and after operation 2 months and half a year, and there was also significant difference in after operation 1 week, 2 months and 6 months ( P < 0. 01). 76 cases survived during 3 years' follow-up, 35 of 36 cases survived in 5 years' follow-up postoperatively (1 case died without definite causes), and the local recurrence was 2 cases, the salvage surgery procedure was total laryngectomy in one patient and wide-field laryngectomy in another.Conclusions: Partial laryngectomy achieves satisfied curative results and provides a clear operative view to resect the tumor completely. Reconstruct the function of the larynx, and improve the voice quality of the patients postoperatively. Therefore, partial laryngectomy is effective for Ti^ T2 ( T1N0M0 , T2N0M0 ) glottic carcinoma.
