Comparative Study of Response Through Reduction in the Size of Hypertrophied Inferior Turbinate Causing Nasal Obstruction by Different Surgical Modalities: A Prospective Study

Abstract

Inferior turbinate hypertrophy is one of the major causes of nasal airway obstruction. Medical treatment often produces insufficient improvement. In these cases, surgical reduction of inferior turbinate can be proposed. Many different techniques are currently available. The aim of our study is to prospectively evaluate the effectiveness of three techniques i.e., electrocautery, cryotherapy and radiofrequency by comparing the response of patients to these three surgical modalities of turbinate reduction. A total of 90 patients presenting with nasal obstruction with or without allergic symptoms, fulfilling the inclusion and exclusion criteria, attending ENT OPD are included in the study. A prospective study was conducted on three groups of thirty patients with symptoms and signs of nasal obstruction associated with inferior turbinate hypertrophy of more than 3 months duration. Then the percentage of subjective improvement in nasal airway is used to assess treatment outcomes 1week, 1, 3, 6, 9 and 12 months after surgery. At the end of 12 months, 56.6 % of patients treated with electrocautery and 56.6 % of patients treated with cryotherapy showed 75 % improvement in nasal obstruction whereas 59.99 % of patients treated with radiofrequency showed 100 % improvement. No statistical difference in the amount of improvement in nasal obstruction was noted between the three treatment groups at the end of 12 months because of relatively small sample size. But clinically radiofrequency showed better subjective improvement in nasal obstruction when compared to cryotherapy and electrocautery.
