A tracheostomy is a surgically made hole that goes through the front of your neck into your trachea, or windpipe. A breathing tube, called a trach tube, is placed through the hole and directly into your windpipe to help you breathe. A tracheostomy may be used to help people who need to be on ventilators for more than a couple of weeks or who have conditions that block the upper airways.
During pathological changes of the sternocleidomastoid the clinical picture of the wryneck occurs (bending of the head to the affected muscle and rotation to the healthy side). A classic example for this condition is the muscular torticollis, a tonic spasm of the sternocleidomastoid.unction. A unilateral contraction of the sternocleidomastoid muscle flexes the cervical vertebral column to the same side (lateral flexion) and rotates the head to the opposite side. A bilateral innervation leads to an elevation of the head (dorsal extension).
