Narrow-band UVB phototherapy of nasal polyps: results of a pilot study

Open, prospective, multicenter study on postoperative intranasal phototherapy in nasal polyposis

BACKGROUND

The therapeutic effect of ultraviolet (UV) light is generally attributed to its immunosuppressive and immunomodulatory effects. Since chronic inflammation is the major factor in the development of nasal polyposis, we have previously used mixed ultraviolet-visible light (mUV-VIS, Rhinolight®) phototherapy for the treatment of nasal polyps.

AIMS

In the present open, multicenter study, our aim was to delineate whether mUV-VIS applied postoperatively in vivo together with intranasal steroid treatment could reduce the recurrence of nasal polyps.

METHODS

After functional endoscopic sinus surgery, one group of patients received mUV-VIS light together with standard intranasal steroid (mometason furoate 2 × 200 μg) application for a 12-week treatment period, whereas the other patient group obtained only intranasal steroid for the same duration. We recorded nasal endoscopy images and obtained demographical and clinical data, total nasal score (TNS), and nasal obstruction symptom evaluation (NOSE). We performed acoustic rhinometry and measured nasal inspiratory peak flow. Follow-up was 12 months.

RESULTS

We found that the recurrence of nasal polyps was significantly diminished, and based on video-endoscopic measurements, the size and grade of recurrent polyps were significantly smaller in the phototherapy-receiving group. Nasal obstruction values and NOSE were significantly better throughout the follow-up period in the mUV-VIS light-treated group than in the intranasal steroid monotreatment group.

CONCLUSIONS

Rhinophototherapy together with standard nasal steroid application may have a supportive role in the treatment of recurrent bilateral nasal polyps.

State of the art treatment of nasal polyposis

BACKGROUND

Nasal polyposis represents the end point of multiple inflammatory pathways and controversy continues as to the exact roles of medical and surgical approaches in the management of nasal polyposis.

METHODS

A combination of both is often required to manage polyps adequately with surgery and intranasal steroids remaining the mainstay of therapy.

RESULTS

Fortunately, new technological advances are making surgery safer and more efficient. In the postoperative period, debridement is effective in reducing the formation of adhesions, and topical medications may play a beneficial role in preventing polyp reformation.

CONCLUSION

Additional investigations into the optimal perioperative medical management is needed to ensure optimal surgical outcomes.
