An investigation was made of applying a pulsed diode laser emitting at the wavelengths of 0.63 to 0.65 micrometers to treat various otolaryngological diseases, such as rhinosinusitis, acute rhinitis, vasomotor rhinitis, allergic rhinitis, the illness of the lymphoid ring, adenoiditis, chronic tonsillitis, pharyngitis, and catarrhal and suppurative otitis. The therapeutic effect produced by the pulsed diode laser was compared with that of conventional therapeutic lasers. It was found that the pulsed low-intensity laser radiation in the red spectrum region offered a number of advantages over conventional laser therapeutic techniques.
