title: Evaluation of cutaneous sensibility on infraorbital nerve area.
abstract: Normal facial sensibility on the area of the infraorbital nerve was determined in 24 healthy subjects. The measurement of two points discrimination distance and the evaluation of cutaneous pressure threshold were assessed on both sides on the zygomatic, paranasal, and superior labial skin. Cutaneous sensibility varied from region to region but was consistent from one normal individual to another. Cutaneous sensibility of the superior labial skin was more accurate than zygomatic and paranasal skin in all tests. Sex and dominant sides did not have significant influence on the results. The measurement of two point discrimination distance and the evaluation of cutaneous pressure threshold provided reliable and reproducible data that can be used as a standard to determine facial cutaneous sensibility.
