Background and Objectives:Conventional turbinoplasty and laser-assisted partial turbinoplasty (LAPT) are commonly performed to control nasal obstruction secondary to inferior turbinate hypertrophy. Coblation, one of radiofrequency electro-compare the postoperative outcome of Coblation-asisted partial turbinoplasty (CAPT) with that of LAPT. Materials and Method:Forty-one patients with nasal obstruction due to inferior turbinate hypertrophy refractory to medical therapy were prospectively evaluated with a folow-up period of 6 months. Twenty-one patients (42 sides) were treated with LAPT, and 20 patients (39 sides) with CAPT. Postoperative changes in degre of nasal obstruction, minimal cross-sectional area (MCA) (V5), operation time, duration of crust formation, operation-associated pain, intraoperative bleeding and episodes of delayed bleeding were compared betwen the two surgical methods. Results:Crust was formed for a shorter postoperative period and operation-associated pain was less in the LAPT group. Nasal patency (MCA and V5) was more improved and operation time was shorter in the CAPT group. However, there were no significant diferences in improvement of nasal obstruction and operation-associated bleeding between the two groups. Conclusion:Thorough knowledge of advantages and limitations of LAPT and CAPT is required for clinicians to make appropriate use of surgical tols for the given patient characteristics and medical environment.
