The long-term results of CO2 laser surgery in 45 patients with perennial allergic rhinitis were reviewed, and compared with the short-term results in 365 patients. Improvement was noted in 78% of the patients one month after laser surgery, and in 76% two years later. Symptoms of nasal blockage, sneezing and nasal discharge did not seem to be different between the short-term and long-term treatment groups. Laser surgery was more effective in younger than in older patients. The results were supported by the histological appearance of the nasal mucosa: a layer of abundant fibrous tissue was evident even 5 years after CO2 laser surgery.
