Q

What is congenital torticollis?

A

CN: Congenital Torticollis is a disorder produced by fibrous tissue tumor which forms in the Sternocleidomastoid M. which causes the head to turn and the face to look away from the affected side. A hematoma can arise and impinge on the Spinal Accessory N. which denervates the Stenocleidomastoid M.
