Trapezius Botulinum Toxin: Baseline Observation of Shoulder Ridge Elevation

Trapezius botulinum toxin administration targets muscular fullness along the junction between the neck and shoulder line. In this pre-procedure photographic assessment, prominent elevation of the trapezius ridge is visible extending from the posterior neck outward toward the shoulder line.

Evaluating muscular prominence along this contour requires precise identification of individual muscle volume and symmetry. Establishing this baseline anatomical ridge confirms the treatment area along the shoulder line prior to neurotoxin injection.
