N2 - BACKGROUND: Since the early 80's, chronic nasal obstruction due to hyperplastic turbinates is treated by laser light. Comparative clinical studies were performed to assess the clinical outcome of laser assisted endonasal turbinate surgery in longterm.METHODS: By means of a pulsed Ho:YAG laser emitting light at lambda = 2100 nm (0.8 - 1.2 J/pulse, 4 - 8 Hz), 69 patients suffering from nasal obstruction due to allergic rhinitis (46 %) and vasomotor rhinitis (54 %) were treated under local anesthesia. Furthermore, 50 patients (52 % with allergic rhinitis and 48 % with vasomotor rhinitis) were treated by means of a GaAlAs-diode laser (c. w., lambda = 940 nm, 8 - 10 W). The treatment time took 3 - 10 min/turbinate and nasal packing was not necessary after the laser procedure. The study was conducted by a standardized questionnaire, photo documentation, allergy test, mucociliar function test, rhinomanometry, and acoustic rhinometry.RESULTS: Within 4 weeks after laser treatment, an improvement of nasal airflow correlating to the extent of the ablated turbinate tissue could be determined in more than 80 % of the patients. Rhinomanometry revealed a significant improvement of the nasal airflow 6 months and 1 year after the laser treatment compared to the preoperative data. Side effects like nasal dryness and pain were rare (< 5 %). Diode laser treatment revealed more effective results than Ho:YAG laser treatment, however there was no significant difference between the two investigated groups. Patients suffering from vasomotor rhinitis showed far better results in long term in comparison to allergic rhinitis patients.CONCLUSIONS: Ho:YAG and diode laser treatment can be performed as an outpatient procedure under local anesthesia in a short treatment time with promising results. It could become a time and cost effective treatment modality in endonasal laser surgery.
