A non-invasive halo-type cervical brace includes an anterior vest overlying the patient's chest and secured tightly by straps extending behind the patient's back. The vest carries a rigid frame structure, including a U-shaped halo frame extending under the patient's chin and around the sides of the patient's head. The halo frame fastens to the frame by upright supports with adjustments aligning the orientation of the halo frame around the patient's head and relative to the anterior vest. A non-invasive halo mask affixed to the halo frame includes a two-part flexible halo immobilized in a position encircling the patient's head, extending generally horizontally around the forehead, the sides and back (occipital region) of the head. The halo includes (1) a semi-rigid forehead band adjustable in length and affixed to the halo frame and extending around the forehead, and (2) a padded occipital support secured against the rear of the patient's head with pressure applied by adjustable straps extending from the occipital support to the halo frame. A flexible trapeze-type chin support affixed to the inside of the halo frame extends under the patient's chin. The chin support is adjustable to apply immobilizing pressure under the chin. The insides of the forehead band and chin support include skin adhesion layers of a non-skid material for frictional contact with the skin to enhance immobilization by avoiding relative motion between the skin and pressure applied by the halo and chin support during use.
