Objective:
The purpose of this prospective, randomized, single-blinded, placebo-controlled study was to investigate the effects of radiofrequency ablation (RFA), diode laser, and microdebrider-assisted inferior turbinoplasty (MAIT) techniques on patients' quality of life (QOL) and to compare the techniques with a placebo procedure.
Methods:
A total of 98 consecutive patients with enlarged inferior turbinates due to persistent year-round rhinitis were randomized into placebo, RFA, diode laser, and MAIT groups at a ratio of 1:2:2:2. All the procedures were carried out under local anesthesia with the patients' eyes covered. Assessments were conducted prior to surgery and 3 months subsequent to the surgery. Quality of life was assessed with the Glasgow Health Status Inventory (GHSI).
Results:
The GHSI total score increased statistically significantly in all the groups, including placebo. There were no significant differences in the GHSI total score change between RFA, diode laser, and MAIT groups. The MAIT procedure improved the GHSI total score significantly more than the placebo procedure (P = .04).
Conclusion:
All inferior turbinate surgery techniques lead to a significant improvement in the patients' QOL, and no significant differences were found between the techniques. The placebo treatment also improved the QOL significantly. Only the MAIT technique improved the QOL significantly more compared to placebo.
