Abstract
The purpose of the study was to examine the various preoperative predictive factors of inferior turbinate surgery and to find possible factors that predict an optimal subjective response using 3 common surgical techniques-radiofrequency ablation (RFA), diode laser, and microdebrider-assisted inferior turbinoplasty (MAIT)-in a randomized, prospective study with a 1-year follow-up. The patients filled a visual analogue scale (VAS) questionnaire regarding the severity of nasal obstruction prior to and 1 year after surgery. A VAS score improvement of 3 points or more was chosen as an optimal subjective response. Univariate and multivariate regressions were used to evaluate the effect of the predictive factors. In total, 80 patients attended a 1-year control visit. In the multivariate analysis, patients without anterior septal deviation had a statistically significantly higher odds ratio of a satisfactory subjective response compared to patients with anterior septal deviation (5.6; 95% CI: 1.4-23.1; P = .02). Patients treated with RFA had a statistically significantly higher odds ratio of an optimal subjective response compared to patients treated with MAIT (9.0; 95% CI: 1.5-54.2; P = .02). Anterior septal deviation seems to decrease the likelihood of an optimal subjective response to inferior turbinate surgery, which supports the consideration of concomitant septoplasty at least in clear cases to optimize the subjective response. Radiofrequency ablation had a significantly higher likelihood of an optimal subjective response compared to MAIT. Further investigations regarding the findings are needed.

Inferior turbinate enlargement due to chronic rhinitis is one of the main causes of chronic nasal obstruction.[1]
The purpose of the present study is to examine various preoperative predictive factors of inferior turbinate surgery and to try to find possible factors that predict an optimal subjective response to inferior turbinate surgery
Some 65% of the patients treated with microdebrider-assisted inferior turbinoplasty (MAIT), 75% with the diode laser, and 89% with Radiofrequency ablation (RFA) had a visual analogue scale (VAS) score improvement for the severity of nasal obstruction of 3 points or more
Summary
Inferior turbinate enlargement due to chronic rhinitis is one of the main causes of chronic nasal obstruction.[1] If the conservative treatment of rhinitis with intranasal corticosteroids does not relieve the nasal obstruction enough, inferior turbinate surgery can be considered.[2,3] Various techniques have been described for the reduction of enlarged inferior turbinates. Radiofrequency ablation (RFA) and microdebrider-assisted inferior turbinoplasty (MAIT) are the most commonly used techniques worldwide,[4] and diode laser treatment has gained in popularity in recent years.[5]. There are not many studies that have evaluated the effect of various possible predictive factors on the results of the surgery Most of those studies have dealt with the predictive effect of the preoperative vasoconstriction test on inferior turbinate surgery results.[6,7,8]
