A method for measuring labial/facial flaccidity, commonly known as a labial/lip, or facial droop. The method includes the use of a labial goniometer, a hand held device, composed of two flat shanks which are joined in the middle by a grommet that serves as a pivot point. The pivot point allows the shanks to be rotated relative to one another. One shank has a double flare/straight edge and the other a double straight edge. The shank with the double flare is calibrated in degrees, over the range of 0 DEG to 30 DEG , above and below a middle reference centerline that runs longitudinally along the entire length of the shank. This design allows for thirty degree measured movement from the centerline of the flared shank in either direction of rotation from the pivot point. With a patient sitting vertically erect, the curved portion of the flared shank is placed horizontally along the labial/lip seal line, directly under the upper lip tubercle and perpendicular to the philtrum. The labial goniometer's circular grommet is placed in direct alignment to the central philtrum, but under the upper lip tubercle. The reference line on the straight edge shank is used to measure the degree of facial droop by adjusting the shank with the double straight edge upward or downward over the degree range. The measurement of labial/facial flaccidity can be made on either side of the patient's labial facial area. |
