Harju T, et al. - In this prospective randomized study, researchers sought to compare radiofrequency ablation, diode laser, and microdebrider-assisted inferior turbinoplasty in the treatment of chronic nasal obstruction in a one-year follow-up, and to pay specific attention to the impact of the procedures on the inferior turbinates contractility capacity. This investigation was performed at Tampere University Hospital, Tampere, Finland, between February 2014 and September 2017. In total, 77 patients attended the one-year control visit and had technically reliable acoustic rhinometry results. In the one-year follow-up, all three techniques reduced the severity of nasal obstruction significantly. Though submucosal fibrosis continued to increase, all the techniques significantly improved the volume of the anterior nasal cavity. Inferior turbinate contractility decreased with every examined technique to the normal level from the preoperative congested state following the surgery.
