We reviewed 235 patients with laryngeal polyps treated by endolaryngeal microsurgery between January,1971 and December,1985. The patients were divided into 3 groups: those with vocal cord nodule, with vocal cord polyp (localized and diffuse) and with polypoid vocal cord.
Localized vocal cord polyp accounted for 49% the laryngeal polyps. Vocal cord nodule was more frequently observed in young adult females whose vocal cords were abused. This study suggested that mechanical stimulation, ageing and smoking were etiologic factors in polypoid vocal cord. However, smoking did not appear to be a factor in vocal cord nodule and localized vocal cord polyp. In addition,40.1% of the patients underwent surgery within one year from the onset of symptomes. The shortest duration of symptomes was observed in localized vocal cord polyp. The post-operative improvement rate was high in polypoid vocal cord.
