Abstract
Objectives:
(1) Compare intramural bipolar electrocautery and radiofrequency coblation in the treatment of inferior turbinate hypertrophy with regard to objective and subjective improvement in nasal obstruction, rate and type of complications, experience during the procedure, and rate of recovery. (2) Describe 2 minimally invasive techniques in the management of turbinate hypertrophy with a comprehensive literature review of the efficacy of these methods.
Methods:
A prospective, randomized, single blinded study from 2008 to 2010 at a single tertiary medical center. Adult patients with inferior turbinate hypertrophy refractory to medical management were randomized to 2 groups based on which nostril they felt to be more obstructed. Patients were then treated with radiofrequency coblation in one nostril and intramural bipolar cautery in the other. Subjective and objective data, including use of a visual analog scale (VAS) for subjective outcomes, acoustic rhinometry, and nasal endoscopy, were then obtained from each patient comparing the 2 techniques.
Results:
Radiofrequency coblation was significantly less painful than intramural bipolar cautery for the early postoperative period (P < .02), was considered less painful during the procedure (P =.03), and produced less crusting at 3 weeks (P = .009). Both interventions were similar in subjective and objective improvements in nasal obstruction as measured by acoustic rhinometry and subjective VAS outcomes.
Conclusions:
Radiofrequency coblation seems to offer an equivalent alternative to bipolar electrocautery for the treatment of inferior turbinate hypertrophy with less discomfort during the procedure and early postoperative period.
