KTP/532 YAG laser treatment for allergic rhinitis

Background: The purpose of this study was to investigate the efficacy of the KTP/532 YAG laser to reduce nasal congestion and discharge in patients with allergic rhinitis. Methods: Forty-eight patients with symptoms of allergic rhinitis were treated with the KTP/532 laser. All had positive skin tests for common allergens. Treatments were provided on an ambulatory basis in one to three sessions under local anesthesia with lidocaine nose spray. Outcome was determined by daily symptom reports and regular endoscopy examination and interviews for 12 months. Results: Treatment was very well tolerated. There were no major side effects. At examination after 1 year, nasal obstruction was improved in 69% and nasal discharge in 40% of cases. Conclusion: The KTP/532 YAG laser is effective for the treatment of nasal obstruction and discharge. Comparison with other techniques showed it to be the most effective in reducing nasal discharge. It can be done as an office procedure and does not damage the nasal mucous membrane, The KTP/532 YAG laser is effective as an additional treatment for patients refractory to medication.
