[Light-guide instruments for low-intensity laser therapy in ORL practice].

Manipulators with monofibre light-guides have been specially designed for otorhinolaryngologic instruments commonly used in routine drug therapy for intracavital treatments. Quartz enclosed in a protective polyethylene sheath is used as the monofibre light-guide with a light conductor 400 microns in diameter and 2 to 3 m in length. It can be built in the following instruments: an ear catheter, a maxillary sinus lavage cannula, a subclavian artery catheter, and a laryngeal bougie. The use of monofibres allows considerable widening the application field of the low power laser therapy in otorhinolaryngologic practice. Moreover, in compliance with human engineering requirements it managed to preserve most standard manipulations otolaryngologist makes use in the course of routine clinical practice with conventional instruments.
