Weinstein enhanced sensory test—D monofilaments, which contain a set of 5 Semmes Weinstein monofilaments designed to evaluate tactile sensitivity in the face, were used to assess sensitivity in 2 locations innervated by the infraorbital nerve. Using a distal branch of the infraorbital nerve for sensory protection resulted in no detectable loss of sensation in the tested distribution of the infraorbital nerve in comparison with the contralateral face.
