Microchirurgie par voie endoscopique au laser CO2 des carcinomes in situ glottiques.

OBJECTIVE: To evaluate the oncologic results of glottic carcinoma in situ (CIS) treated with transoral carbon dioxide laser microsurgery. METHODS: A retrospective review of 12 patients with glottic CIS previously untreated, treated with carbon dioxide laser transoral microsurgery between January 1990 and December 1999 was conducted. RESULTS: Initial and ultimate local control rates were 75%, and 100%, respectively. Three local failures occurred: two glottic CIS were treated by carbon dioxide laser transoral microsurgery, one squamous cell glottic carcinoma was treated by supracricoid partial laryngectomy with cricohyoidoepiglottopexy. The ultimate rate of laryngeal preservation rate was 100%. CONCLUSIONS: Based on the material of this study, recommended treatment for glottic CIS should be carbon dioxide laser transoral microsurgery. Difficulties in endoscopic exposure of the larynx is a contraindication. Further studies are necessary to confirm these preliminary results.
