CO2 laser has been used widely in the treatment of various diseases in the head and neck area. We used CO2 laser in 36 patients with laryngeal cancer (glottis) and in 42 with allergic rhinitis.
CO2 laser was applied via laryngomicrosurgery to laryngeal cancers. Seven patients were not cured by laser and underwent laryngectomy. The patients were followed for 19 to 90 months (mean 48 months). Thirty-five patients (97%) survived without any evidence of recurrence. From this follow-up study we conclude that:
1) T1a can be treated by laser alone, 2) T1b can be treated by laser alone or by a combination of laser and radiation, 3) A careful selection of cases for laser use is required in T2 patients.
The inferior turbinates of allergic rhinitis patients were vaporized by CO2 laser. Improvement of nasal stuffiness was observed in 83% of the patients. Laser did not reduce rhinorrhea or sneezing as well as it did stuffiness. Laser was effective in controlling in 60% rhinorrhea in 54% of the patients treated in, and in controlling sneezing. Laser enables a surgeon to perform the operation with minimum hemorrhage. The patients die not complain of pain during or after operation. The operation can be done on an out-patient basis.
