A specialized hand-portable device for use by a medical-technician in measuring the amount of head fore/aft-deviation from a "standardized norm" reference-point (manubrium of sternum). Configured in the form of an inverted T-shape, the vertical body portion of which serves as a common stanchion, including a horizontal lower scale-beam member having a sternal-probe. The vertical stanchion is adjustable fore/aft relative to the chest sternum; the probe's tip entity being shaped to lay naturally against one's sternal-notch. The upper portion of the stanchion includes a vertically adjustable second horizontal-probe member, the tip-rest thereof being formed to lightly impinge upon the zygomatic-arch region of one's face. The instrument is intitially set to "zero" on the sternal/reference-scale, which precalibration adheres to an "ideal norm" of reference, while leveling to a visual sight-bubble. Hence, consistent measurement deviation (to the millimeter) from this pre-established norm, reveals the patient's precise cranial-deviation relative to the fixed manubrium point. Armed with this data, a suitable correctional program may be prescribed and/or monitored to measure progression toward intended satisfactory results.
