There is no consensus on the ideal management of premalignant lesions of th
e larynx. Published reports describe the use of mucosal. stripping, microsu
rgical techniques, CO2 laser excision and ablation, and even conservation l
aryngeal surgery and radiotherapy. We performed a retrospective evaluation
of 43 men and 11 women who underwent serial excision of dysplastic lesions
with the microflap technique between 1990 and 2001. The average age of the
patients was 57.2 years; 64% had a history of cigarette smoking, and 46% a
history of alcohol consumption. The lesions were located on the middle part
of the left vocal fold in 65% and on the mid-portion of the right vocal fo
ld in 66%. The patients were followed for an average of 4.4 years. Of the 2
0 patients with severe dysplasia or carcinoma in situ treated with the micr
oflap technique, only I progressed to invasive disease. Overall, there was
a reduction in the severity of dysplasia after each procedure (p =.0008). T
he microflap technique reliably reduced the severity of dysplastic lesions
of the vocal fold and was effective in local disease control.
