Effect of facial sensory re-training on sensory thresholds . Nearly 100 % of patients experience trauma to the trigeminal nerve during orthognathic surgery , impairing sensation and sensory function on the face . In a recent randomized clinical trial , people who performed sensory re-training exercises reported less difficulty related to residual numbness and decreased lip sensitivity than those who performed standard opening exercises only . We hypothesized that re-training reduces the impaired performance on neurosensory tests of tactile function that is commonly observed post-surgically . We analyzed thresholds for contact detection , two-point discrimination , and two-point perception , obtained during the clinical trial before and at 1 , 3 , and 6 months after surgery , to assess tactile detection and discriminative sensitivities , and subjective interpretation of tactile stimulation , respectively . Post-surgery , the retrained persons exhibited less impairment , on average , than non-retrained persons only in two-point perception ( P < 0.025 ) , suggesting that retrained persons experienced or interpreted the tactile stimuli differently than did non-retrained persons .
