Conchal contractility after inferior turbinate hypertrophy treatment:A prospective, randomized clinical trial

The aim of this study is to evaluate the effects of these two methods (Nasal corticosteroids (NCS) and radiofrequency (RF) application) on conchal contractility utilizing objective rhinologic measurement parameters. 82 patients were presented with the complaint of nasal obstruction and diagnosed with inferior turbinate hypertrophy and were included in the study. Patients in Group 1 received NCS for 12weeks. Patients in Group 2 were administered RF to their inferior turbinates. Acoustic rhinometry and rhinomanometry tests with and without decongestant were performed. In the evaluation of the contractility difference of rhinometry parameters, there was not a significant difference among pre and postoperative acoustic rhinometric parameters in Group 1. Whereas in Group 2, postoperative contractility difference was significantly decreased compared to preoperative values. In the evaluation of the contractility difference of rhinomanometric parameters, no significant difference was found between pre and postoperative values in Group 1. However, postoperative contractility difference was significantly decreased compared to preoperative values in Group 2 in terms. Because the RF procedure produces fibrosis in the vascular tissues, inferior turbinates do not have a shrinking response to decongestant administration. Administration of NCS administration maintains the contractility function compared to RF application.
