[A new endonasal therapy: the endoscopic YAG laser].

Therapeutical fiberscopy permits ambulatory treatment of benign lesions of the nose and cavum with the use of a flexible endoscope on a patient in the sitting position. YAG gives access to the nasal fossa and, more particularly, to the cavum conchae where it is of the utmost value, since this area is normally inaccessible under local anesthesia. In the cavum, we have been able to treat primarily inflammatory lesions of the adenoids, bridles, cysts, and cases of epipharyngitis and tubal catarrh. In the nasal fossa, although the YAG method provides a means for resorbing hypertrophic conchae, it is of special values for the management of polyposis. The removal of polyps allows to withhold the utilization of adrenal corticosteroids; to delay surgery; or even to reoperate patients with early recurrences. Two ventilation middle meatotomy operations have also been performed. Results from this destructive but precise method are promising.
