ABSTRACT
BACKGROUND AND

OBJECTIVES:

Temperature-controlled radiofrequency inferior turbinate ablation (TCRFA) uses a feedback system to control thermal injury and achieve precise volumetric heating to induce specific scar formation. However, it requires costly single-use proprietary consumables. Comparable volumetric tissue heating may be achieved for a fraction of the cost by adjusting the power settings on traditional monopolar electrosurgery devices that use low-cost needle tips. This pre-clinical study aims to determine the optimized power parameters to achieve electrosurgical coagulum volume similar to that of TCRFA. STUDY DESIGN/MATERIALS AND

METHODS:

An electrosurgery submucosal diathermy (SMD) system (cut mode, 4-32 W, 5-120 seconds) and a temperature-controlled radiofrequency ablation system (standard clinical parameters for treating inferior turbinate hypertrophy) were used to coagulate egg white and chicken breast. Coagulum major and minor axis were measured, and lesion volume was approximated as prolate spheroid.

RESULTS:

No significant difference in volume was found between the temperature-controlled system and the electrosurgery system at 8 W for 30 seconds, 8 W for 60 seconds, 16 W for 30 seconds, 32 W for 5 seconds, and 32 W for 15 seconds. The time to achieve equivalent lesion size was significantly less in the SMD system when compared to the temperature-controlled system (P < 0.05).

CONCLUSION:

Electrosurgery handpieces may achieve similar lesion volume effects as the temperature feedback-controlled, single-use handpieces when set to the optimized parameters. SMD handpieces are significantly more cost and time effective than proprietary devices, and they are easily used in the office. SMD devices may be a more affordable alternative to temperature-controlled systems with comparable lesion volume effect and may be valuable for office-based therapy. Lasers Surg.
