The Nd: YAG laser is used because of its ability to combine its flexible laser fibers with nasal endoscopes. The Nd: YAG is mainly a vaporizing and coagulating laser. Our experiences at our hospital in the management of endoscopic sinonasal diseases with YAG laser are reviewed. The charts of 27 patients who underwent endoscopic surgery with laser from October 1991 through May 1992 were reviewed and were displayed by a VTR-system. The laser fibers may be inserted into channels that are part of a sheath through which the fiberscope may pass or may be taped with the rigid endoscope. The mean age was 41 years (5 years old to 74 years old). 18 patients had chronic sinusitis. 5 of 27 patients had allergic rhinitis. YAG laser, coupled with a 4mm Storz endoscope or flexible fiberscope was used at a spot size. Almost all patients were relieved of a nasal obstruction, and 8 patients reported fewer complaints of nasal discharge or choanal drip. Concerning plain X-ray findings, only 3 cases revealed diminished shadows. 95% of the patients obtained a significantly improved or completely free nasal airway. Using the endoscope, the pyogenic polypose mass can be removed afterward vaporizing and coagulating the tissue. In the case of a polypose mass which may be extensive, and partially blocks, the nasal cavity or middle meatus, foramen fontanelle can be removed eventually by a lasser.
