Conservative surgery in larynx carcinoma
The larynx is the principal organ of the relationship of man´s life, with such important functions as breathing, phonation and swallowing.
Neoplastic lesions of the larynx involves primarily the glottis so that early diagnosis and conservative treatment is more likely than in other body locations. The early tumors classified as T1 and T2 glottic have good results with microsurgical radiotherapy and some of them but mainly those that involve the anterior commissure, classified as T2b, the T1 and T2 supraglottis by its location can be treated with from conservative surgery larynx cordectomy to partial laringectomy. However it is common to find patients with more advanced stages in our service. We present the experience in 18 patients for conservative surgery, showing the evolution and results.
We performed a retrospective cross-sectional study conducted at the ENT and HNS Service in the period between 1993 and 2006 in 115 patients diagnosed with carcinoma of the larynx. Of these, 18 patients (16%) were early carcinomas (T1, T2), of which 8 patients (44%) were glottic and 10 patients (56%) supraglottic
The results of treatment of T1 and T2 glottic cancer are the same as with microsurgery than with CXR.
As an exception is the most effective T1b where open conservative surgery.
In the T1 and T2 supraglottic cancer focus more conservative surgical locoregional radiotherapy gives better results as primary treatment.
There are few treatment protocols including microsurgery, except in small tumors of epiepiglotis, including few Chemo-radiotherapy protocols with gue organ preservation techniques include micro resection.
In relation to the voice CXR eventually leaves better than microsurgery and voice quality after this last one will be better with cold than with laser instruments.
The video strobe is essential for the prognosis of early lesion of the glottis with the observation of the mucosal wave.
