ABSTRACT
Objective To investigate the pathological features and prognostic analysis in endoscopic strip-ping microflap excision of vocal cords leukoplakia.Methods A total of 186 cases with vocal cord leukoplakia and treated by endoscopic stripping microflap excision were retrospectively analyzed,calculated the ratios of recurrence and malignant transformation on keratosis without dysplasia,mild dysplasia,moderate dysplasia and severe dysplasia and carcinoma in situ.Then,the association of histopathological classification with recurrence and malignant transformation in vocal cord leukoplakia were evaluated.Results 87 cases of all 186 patients with vocal cord leukoplakia were kera-tosis without dysplasia,17 cases were recurrenced and 3 cases were developed to carcinoma;64 cases were mild dysplasia,15 cases were recurrenced and 7 cases were developed to carcinoma;29 cases were moderate dysplasia, 13 cases were recurrenced and 10 cases were developed to carcinoma;6 cases were severe dysplasia and carcinoma in situ,all 6 cases were recurrenced and 5 cases were developed to carcinoma.Conclusion The histopathological classi-fication is predictive factor for the risk of recurrence and malignant transformation in vocal cord leukoplakia.
