Introduction: The aim of our study is to present our experience in treating laryngeal cancers with endoscopic CO2 laser surgery.

Materials and Methods: This retrospective study was conducted from January 2008 to December 2012 at Antoine Lacassagne Center of Nice. The functional and oncologic results of this surgical technique were analyzed and discussed.

Results: The average length of hospital stay was 2.5 days. Phonatory results were considered excellent in 75% of our patients who maintained satisfactory phone communication skills after their interventions. Chronic hoarseness was the most common reason for bilateral or extended cordectomies. On the oncologic basis, histologic exam showed 90% of our margins were normal. The clinical control showed excellent laryngeal preservation in 94.23%. In 5 years, the overall survival was estimated at 96.15%.

Conclusion: This study shows the benefit of the laser endoscopic microsurgery for the preservation of laryngeal functions and the local histologic control, essentially for early stage laryngeal cancers.
