Abstract

 

BACKGROUND:

Allergic rhinitis and nasal polyposis are common nasal diseases, but the available treatment modalities have only limited success.

 

OBJECTIVE:

To assess the therapeutic effect of low-energy narrow-band red light phototherapy on nasal clinical symptoms of allergic rhinitis and nasal polyposis.

 

METHODS:

In a double-blind randomized prospective study, 50 patients with allergic rhinitis and 10 with nasal polyposis received intranasal illumination at 660 nm for 4.4 minutes three times a day for 14 days (total dose 6 joules per day). Twenty-nine rhinitic patients and one patient with polyposis received equivalent sham illumination as placebo. Evaluation was based on symptom scores and a clinical assessment that included pre-treatment and post-treatment videotaped rigid and flexible nasendoscopy.

 

RESULTS:

Following treatment, improvement of symptoms was reported by 72% of the allergic rhinitis patients and objective improvement was endoscopically demonstrated in 70% of them as compared with 24% and 3%, respectively, in the placebo group. These differences were significant. No improvement was obtained in any of the patients with polyposis.

 

CONCLUSIONS:

Allergic rhinitis, if uncomplicated by polyps or chronic sinusitis, can be effectively treated by narrow-band red light illumination of the nasal mucosa at 660 nm, with marked alleviation of clinical symptoms. Whenever possible, candidates for phototherapy should be selected by endoscopic examination. Should be selected by endoscopic examination.
