Carbon dioxide laser vaporization for turbinate: optimal conditions and indications

Auris Nasus Larynx. 2000 Apr;27(2):137-40. doi: 10.1016/s0385-8146(99)00061-9.


Carbon dioxide (CO2) laser vaporization for turbinate has rapidly gained acceptance in Japan for the treatment of allergic rhinitis.

Objective: The aim of this study was to examine the effects of laser output, patient age, and the presence of a deviated nasal septum on treatment outcome in patients with intractable allergic rhinitis.

Methods: The inferior turbinates were irradiated at an output of 3 or 5 W for 0.1 s.

Results: Of 67 patients, 43 (64.2%) were judged to have symptoms which improved markedly or moderately after a single treatment. Treatment was more effective with a laser output of 5 W than with an output of 3 W. However, treatment was judged less effective in patients aged 15 years or less than in older patients. The presence of a slightly deviated nasal septum had no effect on treatment outcome.

Conclusion: Although assessing outcome on the basis of symptoms is difficult, we believe that these findings will suggest the optimal conditions and indications for laser surgery for allergic rhinitis.
