Facial sensibility testing in the normal and posttraumatic population.

A reliable, reproducible, simple examination of facial sensibility is described. Evaluation of 60 healthy subjects established normal values, trends, and variations of facial sensibility. Comparison of these normal values with 20 posttraumatic patients revealed that postfacial fracture sensibility testing was abnormal. Abnormalities in pressure threshold testing was most consistently associated with functional sensory complaints. Twelve of the 20 patients had significant sensory complaints at one year following the trauma.
