Diode laser treatment of hyperplastic inferior nasal turbinates.
Background and Objective Different laser types have been used for the treatment of hyperplastic inferior nasal turbinates. The clinical experiences of its treatment by means of a diode laser are presented. Study Design/Materials and Methods A total of 76 patients suffering from nasal obstruction due to hyperplastic inferior nasal turbinates were treated with a continuous diode laser (wavelength of lambda = 940 nm, laser parameter 10 W/energy/turbinate 5 kJ) in "noncontact" mode and under local anesthesia. All patients were refractory to conservative medical treatment. Fifty patients (26 of 50 [52%] with allergic rhinitis and 24 of 50 [48%] with vasomotor rhinitis) were included into this clinical trial with a follow-up of 1 year. The study was conducted by a questionnaire, photo documentation, allergy test, mucociliary clearance test, rhinomanometry, acoustic rhinometry, conventional radiology of the paranasal sinuses, and histology.


RESULTS
The mean operation time took 6 min/turbinate, no nasal packing was necessary and no immediate complications (e.g., major bleeding) were observed. During the first 2-4 weeks, nasal obstruction was correlated to the extent of postoperative edema and nasal crusting. Statistical analysis revealed significant improvement of the nasal airflow (rhinomanometry) and nasal cavity volume (acoustic rhinometry) 6 months and 1 year after laser surgery, respectively. A total of 86% of the patients described a subjective improvement of nasal airflow 6 months and 76% of the patients 1 year after laser treatment. The mucociliary function test showed no significant variation in comparison to the preoperative measurements 1 year after laser treatment.


CONCLUSIONS
Diode laser treatment of hyperplastic inferior nasal turbinates is a useful procedure, which can be performed as an outpatient surgery under local anesthesia, resulting in a controlled coagulation and ablation of the soft tissue. The short operation time and the good results provide an excellent patient acceptance.
