Since the Jako 20 Century 70's introduction of laser technology to the ENT field, many scholars have tried to various laser for the treatment of chronic rhinitis .all the many advantages of laser performance. The author in August 2002 to February 2003 under nasal endoscopy during the use of GaAlAs semiconductor laser treatment for the treatment of 32 patients with chronic rhinitis patients achieved satisfactory results.

1.           materials and methods

1.1   clinical data 32 patients were 18 males and 14 females, aged 17 to 72 years, mean 39 years, persistent nasal obstruction for more than six months, up to 8 years, part of a runny nose, tinnitus, dripping with decongestants is not sensitive; who had no history of nasal and sinus surgery; sinus CT exclude sinusitis, nasal polyps, turbinate bone hypertrophy. Nasal endoscopy, bilateral in 18 cases of chronic hypertrophic rhinitis, allergic rhinitis and 8 cases, 3 cases of chronic simple rhinitis, nasal septum deviation and inferior turbinate back with varying degrees of proliferative lesions in 3 cases.

1.2   Treatment methods Nasal endoscopy (Stryker Corporation production), diameter 4 mm 0 ° endoscope angle view, TV monitoring system (Trinitron Color Video Monitor, 1998 by Sony corporation), using the GaAlAs diode laser therapy, a wavelength of 810 nm, maximum output power of 25 W, with 600μm SMA905 standard output fiber (contact), aiming beam for the 650nm red laser diode.

Patients were supine, with 1% tetracaine cotton pad into the nasal cavity three times as the mucosal surface anesthesia, hypertrophic mucosa at the back end of middle turbinate can use 1% lidocaine local anesthesia under endoscopic screening recess butterfly . Fiber laser output issued in endoscopic nasal turbinate hypertrophy and polypoid changes organizations, output power 12 ~ 15 W, laser light with continuous output mode, along the free margin of the inferior turbinate direct gasification front to back, to the organization contracted the nasal cavity to form a good airway and the back end of inferior turbinate, the exposed area after the nostril diameter not less than 5mm. Observe patients after 1 h, no bleeding, and adverse reactions. 1% ephedrine nasal cavity, 5% cortisone alternating nasal fluid, clear nasal discharge 2 times, 1 week after basically no nasal discharge, 2 weeks to recover basic .
