One of the most preferred surgical metod is radiofrequency tecnique. Coblation submucosal reduction turbinator (SCT);new surgical device; started to use recently. Since the method is new, very few study has been done yet. We compare coblation radiofrequency (CR) with SCT. Material and methods: Patients with only inferior turbinate hypertrophy but no other diseases included in study. Paranasal CT was made to all patient to rule out turbinate bone hypertrophy. Group 1 32 patient; performed CR. Group 2 25 patients performed SCT. To all patients preoperative and 3 weeks later post operative mucosiliary activity test was performed. Nasal flow was measured with nasal flow meter preoperatively and 3 weeks post operatively. VAS and NOSE was measured. Results compared between two groups. SCT performed under general; CR performed under local anesthesia. Results: There was significant nasal flow changes in CR group. (p < 0.001) There was no difference in pre-and-post operatively saccharin test results in CR group. (p = 0.385) There was slightly nasal flow gain in SCT group but this was not statistically significant. (p < 0.192) Also there was no statistically significant changes in pre-and-post operatively saccharin test results in SCT group. (p = 0.167) There was no difference between two groups in terms of post operative nasal flow values and mucociliary activity. (respectively p = 0.562, p = 0.355). (Table 2). Both two tecnique has significant increase in VAS and NOSE scores. (p < 0.001). Conclusions: According to our study two tecnique is suitable and safe for nasal mucociliary activity. Tecniques has positive effect on nasal flow, VAS and NOSE scores. 1. Introduction Inferior turbinate is a structure that has important functions in nasal physiology. It has important functions in filtering, heating, humidifying the air taken and adjusting the nasal airflow [1,2]. However, hyper- trophy of the inferior turbinate decreases the nasal flow and causes nasal obstruction. Inferior turbinate hypertrophy is one of the most frequently seen reasons of nasal obstruction [3]. Medical treatment is the first-line treatment for this condition, which is frequently encountered in daily ENT practice. Saline spreys, nasal steroids, oral antihistamines, nasal antihistamines and oral montelukasts are frequently used in medical treatment. Surgical treat- ment comes to the fore in the cases that do not respond to medical treatment [4]. There are many surgical methods that are developed for inferior turbinate hypertrophy. Foremost among them inferior turbinate later- alization, submucosal resection, laser reduction, electrocauterization, and radiofrequency reduction take place [4,5]. Radiofrequency inferior turbinate reduction involves the direct ap- plication of a high-frequency current to the inferior turbinate, friction between inferior turbinate ions lead to submucosal damage. This thermal energy is lower than other cautery techniques but generated energy cause enough submucosal injury. Technique is popular because it can be applied by local anesthesia [6,7]. Several devices designed for radiofrequency. In our daily practice we use coblation radiofrequency (CR) device (Coblation™ Reflex). The wand is inserted in to the turbinate and activated for 10 s. Probe can be used several times during surgery to provide reduction on turbinate [4]. As the technology progresses, new devices are being used for in- ferior turbinate reduction. Inferior turbinate submucosal coblation turbinator (SCT) has become a new method. In this method, the tur- binate incised vertically to entry and mucosa is elevated and a tunnel created. Submucosal reduction is performed in the tunnel with the help of coblation turbinator wand (Coblation™ Turbinator™). Since the method is new, very few study has been done yet [8]. Coblation Turbinator™ is the first wand designed specifically for turbinate surgery and has an actice electrode that produces the plasma field. It has intergrated irrigation, bipolar an suction connected. It was found to be a safe technique [8]. For these reason, we wanted to compare this new technology with radiofrequency that our traditional technology for reduction turbinate surgery. Thus it was aimed to determine whether this novel technology could replace the radiofrequency inferior turbinate surgery. https://doi.org/10.1016/j.amjoto.2019.05.019 Received 17 March 2019 ⁎ Corresponding author at: Ankara Ataturk Reseach and Training Hospital, Turkey.
