This report describes a ''trap door'' exposure of the cervicothoracic
junction. The method combines a standard anterior approach to the spin
e along the medial border of the sternocleidomastoid muscle with both
a partial median sternotomy and an anterolateral thoracotomy. Transect
ion of the clavicle is not required and the sternoclavicular joint is
preserved. With this method, all important ventral paravertebral vesse
ls, nerves, and associated soft tissue are fully identified and readil
y mobilized as needed. The method provides full bilateral anterior exp
osure from the C-4 through at least the T-3 vertebral levels, as well
as unilateral anterolateral access to the upper thoracic spine.
