[Laser treatment of sinusitis in general practice assessed by a double-blind controlled study]

The effect of Low Level Laser therapy (Galium-Aluminium-Arsenide laser, 30 mW/830 nm, Unilaser 2000 3B) on sinuitis was evaluated in a double-blind randomised clinical study comprising 60 patients from general practice. All patients received three treatments (90 seconds radiation on each sinus) with one to three days interval. No statistically significant differences in pain relief, well-being or duration of illness were observed between patients treated with laser and a placebo.
