Life-size photograph transparencies: a method for the photographic detection and documentation of recovery from facial paralysis.

We describe a simple and objective practical method for the detection of recovery from facial paralysis by multiple photographic assessments. The photographs are printed as life-size transparencies representing maximal effort. Each time the patient attends for review the new transparency is overlapped on the previous one and the difference can be detected easily. The prints are filed with the patient's notes for future reference. To achieve this system a specific photographic protocol is mandatory in order to avoid technical artefacts. We believe that this system avoids many of the complexities of other grading systems and is very suitable for use at outpatient follow-up.
