Tumescent lidocaine is one protocol that is used in treatment as the panel has laid out. The justification for tumescent lidocaine is to provide a larger distance between underlying structures and the targeted pilosebaceous units. MiraDry can be painful due to collateral heat and theoretically this can reduce the risk of nerve injury from microwave heating. Prior to receiving treatment I would recommend asking your provider what protocol they utilize and why. The tumescent lidocaine protocol is considered to be safer and more comfortable with few side effects (e.g. edema of local tissue).
Yes, this is the new protocol. Better results and more comfortable. It's also safer for the deeper tissue. Best wishes, Dr. ALDO
