1. A cervical collar including an anterior component for coupling to a posterior component having an anatomical contour to circumferentially surround a neck, and a mandibular support having an anatomical contour and coupling to the anterior component, the anterior component defining a vertical centerline, the anterior component comprising:
an upper part arranged for receiving the mandibular support, the upper part having first and second wing portions extending from a central portion of the upper part, the upper part having a tab extending from an upper peripheral segment of the upper part at the central portion thereof and adapted to secure to the mandibular support;
a lower part connected to the upper part, the lower part having first and second wing portions extending from a central portion of the lower part, the first and second wing portions of the lower part are pivotally connected to the first and second wing portions of the upper part, respectively;
first and second fasteners fixably attached to the first wing portions and the second wing portions of the upper and lower parts, respectively;
wherein the cervical collar forms a tracheal opening centrally located on the anterior component, the tracheal opening has a periphery defined by a lower peripheral segment of the upper part and opposite the upper peripheral segment, and an inner peripheral segment of the lower part located at the central portions, thereof;
wherein the lower part defines first and second slots located on opposite sides of the tracheal opening, third and fourth fasteners extend through the upper part and engage the first and second slots to facilitate height adjustment of the tracheal opening by relative movement of the lower part along the third and fourth fasteners guided by the first and second slots;
wherein height adjustment of the upper part relative to the lower part maintains connection of the mandibular support and the posterior component to the anterior component and the anatomical contours of both the mandibular support and the posterior component;
further comprising a height mechanism connecting to the upper and lower parts for maintaining the height of the lower part relative to the upper part, the height mechanism being located above and outside of a sternal support;
wherein the height mechanism includes a tensioning device connected to the upper part and arranged on the vertical centerline, wherein the tensioning device is mounted on an outer surface of the upper part, the tensioning device is rotatable around an axis perpendicular to and intersecting the vertical centerline;
wherein at least one cable engages between the upper and lower parts and is arranged to be shortened or lengthened for height adjustment relative to the upper and lower parts by the tensioning device to move the lower part relative to the upper part;
wherein a height of the tracheal opening is arranged to vary according to a length of the at least one cable, wherein the tensioning device is located on the upper part above the tracheal opening.
