Conventional protocols typically involve injecting across the entire muscle, necessitating a high number of injection points and larger total doses, which may increase the risk of bruising, patient discomfort, and potential immunogenicity. Recent anatomical studies using Sihler's staining have demonstrated that motor innervation is predominantly concentrated in the upper portion of the platysma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims<\/jats:title>\n                    <jats:p>To evaluate a neural distribution\u2013based BoNT\u2010A injection strategy targeting only the motor\u2010rich upper platysma, compared with the conventional whole\u2010muscle injection approach.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifteen patients with prominent platysmal bands received BoNT\u2010A injections (JETEMA THE TOXIN, JETEMA Inc., Korea) in a split\u2010side design: The right platysma was injected using a conventional 30\u2010point technique, and the left platysma received 15 targeted injections in the upper portion based on mapped motor entry points.
