Abstract
A method for cryogenically treating a target tissue comprises providing a cryogenic device having one or more tissue penetrating needle probes, and advancing the one or more tissue penetrating needle probes through skin disposed above the target tissue into the target tissue. The target tissue comprises a motor nerve. The method also includes cooling the target tissue with the one or more tissue penetrating needle probes, and temporarily disrupting signal conduction from the motor nerve thereby preventing contraction of a muscle operably coupled to the motor nerve. This reduces or eliminates hyperdynamic wrinkles of a patient's face.
