The Efficacy of Coblator in Turbinoplasty

Abstract

BACKGROUND Turbinate hypertrophy is one of the common causes of chronic nasal obstruction. In principle, therapeutic guidelines recommend medical treatment. Failure to treat turbinate thickening despite drug therapy may indicate the need for surgery. The main aim of this study was to determine the effect of radiofrequency surgery, among various other surgical procedures, on people with both nasal septal deviation and turbinate hypertrophy. METHODS Among people with nasal deviation who visited the subject hospital between July 2008 to July 2014, 21 people with nasal septal deviation and severe turbinate hypertrophy before their surgery had undergone septoplasty with turbinoplasty using radiofrequency combined with septoplasty. The degree of the turbinate's hypertrophy was appraised in all the patients before and after the surgery using the rhinoscopy, and acoustic rhinometry was objectively carried out. The subjective effect of the turbinoplasty using radiofrequency was explored through the visual analog scale (VAS) score. RESULTS The degree of contraction of the nasal mucosa after the rhinoscopy changed from Grades 3 and 4 (100%) to Grades 1 and 2 (95.2%) and Grades 3 (4.8%). The minimal cross-sectional area significantly increased from 0.44±0.07 to 0.70±0.07 cm2 (p<0.05). The nasal cavity volume increased from 4.79±0.49 to 6.76±0.55 cm2 (p<0.05). The subjective symptoms evaluated with VAS score a year after the surgery significantly improved (p<0.05). CONCLUSION Turbinoplasty using Coblator with septoplasty is an effective treatment method because it expands nasal cavity, has a low incidence of complications, subjectively improves symptoms, and has short treatment duration.
