Abstract

Clinical studies were performed to assess the clinical outcome of laser assisted endonasal turbinate surgery in long-term. By means of a pulsed Ho:YAG laser emitting at (lambda) equals 2100nm 57 patients suffering form nasal obstruction due to allergic rhinitis and vasomotoric rhinitis were treated under local anesthesia. Furthermore 50 patients were treated by means of light of a diode laser. The light was fed into a fiber being introduced into a fiber guidance system which serves for suction of smoke and pyrolyse products. The distal part of this system could be bent in the range of -5 degrees up to 45 degrees due to the optical axes of the fiber. The study was conducted by a standardized questionnaire, photo documentation, allergy test, mucocilliar function test, rhinomanometry, radiology and histology. Within 2 weeks after laser treatment a significant improvement of nasal airflow correlating to the extent of the ablated turbinate tissue could be determined. This effect lasted up until 1 year post treatment resulting in an improved quality of life in more than 80 percent of the patients. Side effects like nasal dryness and pain were rare, no immediate complications were observed. The total treatment time took 3-8 minutes/turbinate and nasal packing was not necessary after the laser procedure. In conclusion laser treatment by means of the fiber guidance system can be performed as an outpatient procedure under local anesthesia with excellent ablation of soft tissue in a short treatment time with promising results. It will become a time and cost effective treatment modality in endonasal laser surgery.
