title: Endoscopic correction of eyebrow asymmetry in associated forehead soft-tissue injuries.
abstract: Supported by anatomical principles, a subgaleal endoscopically assisted selective myotomy of the forehead and glabellar muscles was used to achieve eyebrow symmetry in patients with unilateral facial nerve palsy and associated forehead soft-tissue injuries. Selective myotomy equalizes the agonist-antagonist muscle relationship on both sides of the forehead, thereby allowing the untouched muscle to exert its activity without opponent restriction. Selective myotomy allows for the management of the muscles' group action as well as individual manipulation of each muscle in accordance with its participation in the eyebrow deformity.
