Normal cutaneous sensibility of the face.

Abstract

Normal values for facial sensibility were determined in 36 healthy subjects. Sensation was evaluated using static and moving two-point discrimination and pressure and vibratory threshold in four major regions of the head and neck. Each region was directly related to the area innervated by a particular peripheral sensory nerve (supraorbital, infraorbital, inferior alveolar-mental, or the great auricular nerve). Cutaneous sensibility varied from region to region but was consistent from one normal individual to another and in the same subject on different days. Measurements of pressure and vibratory thresholds provided the most reliable, reproducible data. A relationship of these data to the types of sensory receptors in facial skin and vermilion is postulated.
