BACKGROUND: Phototherapy has a profound immunosuppressive effect, and phototherapeutic methods using both ultraviolet (UV) and visible light are therefore widely used for the therapy of various inflammatory skin diseases. It is also proposed that phototherapy, using a combination of UV-A (25%), UV-B (5%) and visible light (70%), may represent a therapeutic alternative in patients with allergic rhinitis.
METHOD: Seventy-nine patients were randomly assigned to receive either a combination of UV-A (25%), UV-B (5%) and visible light (70%), in the phototherapy group, or low-intensity visible light, in the control group. The efficacy of treatment was assessed by means of total nasal symptom score before treatment and 1 month after the end of treatment.
RESULTS: Total nasal scores decreased in both groups but the decrease was highly significant in the active treatment group when compared with the placebo (p < 0.001).
CONCLUSIONS: This study demonstrates that phototherapy may be an effective modality in the treatment of allergic rhinitis especially in cases of which commonly used drugs either are contraindicated and/or have insufficient efficacy.
Highly sensitive instrumental methods such as rhinopneumography, rhinorheography, rheoencephalography and segmented sphygmography were used to measure the efficacy of contact laser therapy of the pterygopalatine ganglion to treat vasomotor rhinitis and trigeminal neuralgia. This method proved efficient in the case of the nervous form of vasomotor rhinitis, Sluder syndrome, and trigeminal neuralgia. Stable remission developed in 60% of patients.
Magnet-laser therapy was used to treat vasomotor rhinitis in 90 patients. A constant magnet of 50 mT was applied to the exterior of the nose, and an infrared laser beam was applied via a light-guide to the reflexogenic zones of concha inferior. The radiation power density was 5 mW/cm2. The magnetic exposure time was 6-10 min and the laser exposure time was 3-5 min for each half of the nose. The therapeutic course was 8-12 sessions. The therapeutic results depended on the type of vasomotor rhinitis, clinical disorders, and duration of the disease. Good results were seen in 84 (93.3%) patients out of 90 cases. Stable remission was recorded in 61.1% patients, significant improvement of clinical manifestations of vasomotor rhinitis was observed in 32.2% cases. Best results were reported in patients with autonomic forms of vasomotor rhinitis who suffered from short-term disease and vasodilation disorders.
