Between the prominent sternal origin and the broad ribbon-like clavicular origin is a slight triangular depression which overlies the inferior part of the internal jugular vein. By dividing the cervical fascia along the anterior and posterior borders of the muscle the surgeon is able to retract it backwards and forwards so as to obtain free access to the structures deep to it. If the posterior fibres of the muscle are divided at their clavicular and mastoid attachments the muscle can be still more freely mobilised. In dividing the fascia along its posterior border the cutaneous branches of the cervical plexus are generally divided, but care is taken not to injure the accessory nerve. Should it be found necessary to remove the upper third or more of the muscle, the divided end is stitched to the levator scapulae or to the scalenus medius, according to the amount resected. In dividing the muscle completely across at the lower part of the neck, as is done, for example, in congenital wry-neck, the close relation of the anterior and external jugular veins to its corresponding borders must be kept in mind.
