Subjective results of laser surgery for allergic rhinitis

Inferior turbinates of 389 patients with perennial allergic rhinitis were vaporized by a defocused carbon dioxide (CO2) laser beam, using specially designed handpieces. This laser surgery can be done under local anesthesia as an outpatient procedure, with no pain or bleeding. One month after laser surgery, 78% of 389 patients had excellent or good results, while 21 had no improvement, subjectively. Seventy-two of 389 patients were followed for over 2 years, and 61 of the 72 had excellent or good results. Twenty-seven of the 72 cases need revaporization because of recurrence. Patients with relapse less than one year after surgery had little improvement in subjective symptoms, even after revaporization; while patients with relapse more than one year after surgery responded well, and long-term results were favorable. All things considered, laser surgery is an effective treatment for perennial allergic rhinitis.
