hi,
thanks for sharing. i rarely perform subcision as i find it does not help that much in most acne scars. in other types of tethered scars featured in the article, that makes more sense. i think nerve damage across the entire face is pretty unlikely since nerves emanate very deep below the muscle except in the temple region where they lie more superficially. in that one area and also under the mandible (jawbone) the nerve can lie more superficially. in the cheek, you should be fine. in the central forehead, the nerve is a bit variable but theoretically could be injured if coming up right over the eyelid area where it terminates. it depends on the exact location but in general it is pretty hard to damage facial nerves with subcision technique in most of the face.
