Effectiveness of classical chordectomy in the treatment of cancer of the glottis.

From 1980 to 1992, 85 patients diagnosed with tumour of the glottis, localized exclusively in the vocal cord area, had undergone surgery. A 90% 5-year survival rate without recurrences had been obtained. Taking into account the cases of life-saving surgery, the percentage of the 5-year survivals amounted to 94%. Considerably better results were obtained by the excision of the entire vocal cord and not just one of its sections (1/2, 2/3 etc.). The degree of deformation of the voice following chordectomy was assessed by means of acoustic and laryngographic methods (Laryngograph Processor PCLX). A 13% rate of irregularity in the functioning of the neoglottis, following surgery, was observed. The Jitter-Shimmer co-efficients were established. The results of the deformation of the voice following chordectomy were presented on the J-S scale and compared with other partial surgeries performed on patients with tumours of the glottis. All of the acoustic and laryngographic findings were presented in the from of mean values most representative of chordectomy.
