[Clinic and pathological analysis the larynx leukoplakia in 74 cases].

OBJECTIVE

To study the clinic and pathological features of leukoplakia of the larynx, and reduce canceration rate.

METHOD

Seventy-four postoperative patients of leukoplakia of the larynx were followed up for four years by telephone or clinic service.

RESULT

None of eighteen cases of pure leukoplakia was recurrence. Fifty-six cases were leukoplakia with epithelial dysplasia histologically. Seven out of fifty-six postoperative cases occurred hoarseness; three out of fifty-six postoperative cases recurred, and accepted twice or more operations successively; three out of fifty-six postoperative cases occurred canceration.

CONCLUSION

Operation is the main means for the treatment of leukoplakia of the larynx, and the effect is comparatively well. The patients with histological epithelial dysplasia should be pay great attention because of their higher canceration rate, and enlarged operation ranges appropriately with the patient consent could effectually prevent recurrence or canceration during the early lesions. Close observation is important for these patients.
