✦ Synopsis
To present a new concept of outcome analysis after immediate reconstruction of traumatic lesions of the frontal branch of the facial nerve. With the aid of laser surface scanning, changes induced by frontal muscle contraction, i.e. frowning, in skin surface area on the forehead were measured in nine patients after repair of traumatic transection of the frontal branch of the facial nerve and in 10 healthy volunteers. With laser surface scanning analysis, consistent changes in surface area on the forehead were measured in both patients and healthy volunteers. Symmetry of 74±15% in forehead wrinkling was obtained 12 months after coaptation of the transected nerve. Laser surface scanning is a promising tool to assess outcome after repair of facial nerve laceration. It is easy to use, yields reproducible results and might be used in the future for other procedures.
