Coblation lesion formation in a porcine tongue model

The porcine tongue model describes the relationship between lesion size and cold ablation device settings. Setting, but not time, significantly affects lesion size. The coblation setting and treatment time directly impact the amount of energy delivered. Additionally, submucosal normal saline injection significantly increases lesion size at all settings and application times. Given the average lesion diameter described in this study, placing lesions 1 cm apart will optimize the area affected by coblation while minimizing lesion overlap.
