Objective:
To study the clinical characteristics of different potassium titanium phosphate(KTP) laser types and surgical the recuperating course of cordectomy under suspension laryngoscope.
Method:
Follow-up observation were applied on 76 patients with cordectomy. Restoration of laryngeal structure and change of the quality of voice were observed and recorded.
Results:
Type 1, normal laryngeal structure and function were restored postoperatively after 3 months; Type 2, a fold like vocal cord (new vocal cord) appeared 3 months later. Laryngeal structure was basically restored; Type 3, a mucosal fold appeared postoperatively after 6 months in most patients, but it lost motion function. Recurrence time was mainly found 2-4 months. Recurrence rate was 6.7%. Two and 5-year survival rate were 100%.
Conclusions:
Cordectomy with KTP laser can result in good effect and less injury. Type 2, 3 can retain thyroarytenoid muscle as much as possible on the basis of radical cure.
