[Minimally invasive treatment in early glottic cancer and vocal cord dysplasia].
OBJECTIVE
To investigate the pathologic and clinical diagnosis of early stage glottic carcinoma and the vocal cord dysplasia and the results of the minimally invasive treatment.


METHODS
Thirty-two cases of early glottic cancer (T1N0M0) and 20 cases of vocal dysplasia were treated with mucous stripping and minimally invasive cordectomy under the micro-suspension laryngoscope. The pathomorphology was observed with continuous sections.


RESULTS
After 3-4 years follow-up, 26 cases of early glottic cancer remained tumor free, 3 cases relapsed and 2 cases received the re-stripping operation. twenty cases of vocal cord dysplasia were classified as: leucoplakia of vocal cord, mild atypical hyperplasia, moderate atypical hyperplasia and advanced hyperplasia. None of them had malignant change after 3 years follow-up.


CONCLUSIONS
The laryngeal micro-operation under the micro-suspension laryngoscope is an effective and safe cure procedure, it provides a definite diagnostic method for the early stage glottic carcinoma and the vocal cord dysplasia.
