Quantification of functional results after facial burns by the faciometer.

In the present study the faciometer(R) is introduced in order to quantify the ranges of mimic movements observed after surgical treatment of facial burns. This instrument which consists of calipers and an electronic display was introduced in 1994 in order to measure the extent of facial palsy during reconstructive procedures. The study group consisted of 23 patients, who had been operated on for facial burns. The distances between standardised stable and moving points in the face were determined after mimic movements such as lifting of the eyebrows, maximum showing of the teeth and pursing of the lips. These distances were expressed as a percentage of the distance at rest. For comparison the scars were classified according to the Vancouver Scar Scale. In all patients the functional results after burn trauma in the face and, in some cases, asymmetries at rest could be objectified. Depending upon the severity of scarring, the distance between tragus and mouth was shortened between 0 and 19% after maximal showing of the teeth. In general the mouth region showed more functional deficits than the forehead. Comparing different manners of treatment, it could be objectively demonstrated that the results after deep burns requiring skin grafts were worse than those observed after more superficial lesions and other methods of coverage. The application of keratinocytes to close the burn showed highly variable results.
