Effect of Low Reactive Level LASER Treatment for Foreign-Body Sensation in the Throat

Abstract

A double blind test was performed to evaluate the effectiveness of low reactive level laser (soft-laser) treatment for foreign-body sensation in the throat. One hundred and twenty patients with foreign-body sensation in the throat were studied. Sixty-six patients were treated with soft laser irradiation to the superior laryngeal nerve through the cervical skin. The other 54 patients served as a placebo group. The effectiveness of the treatment was compared between the two groups. An immediate remission of the foreign body sensation was observed in the patients with irradiation more than that of the placebo group. A significant difference of the remission of the foreign body sensation was observed just after the laser treatment (P=0.0175). No side effects were observed in any of the patients. It was concluded that soft-laser treatment was an effective and safe treatment for foreign-body sensation in the throat.
