What is the ideal tissue temperature range for RF tissue ablation?

The ideal tissue temperature range for RF (radiofrequency) tissue ablation is indeed between 50-90 degrees Celsius. This temperature range is critical because it is sufficiently high to achieve effective coagulation and necrosis of the targeted tissue without causing excessive damage to surrounding healthy structures. At temperatures below 50 degrees Celsius, the efficacy of the ablation process is significantly reduced, as tissue heating is insufficient to disrupt cellular integrity. Conversely, temperatures higher than 90 degrees Celsius can lead to unintended thermal injuries, potentially resulting in complications such as charring, which can impact the quality of the ablation and result in impaired healing or even damage to adjacent tissues. Therefore, maintaining tissue temperatures within this specific range ensures both the effectiveness of the procedure and minimizes risks associated with overheating.
