A comparison of neurosensory alteration and recovery pattern among different types of orthognathic surgeries using the current perception threshold

Short-term effects of orthognathic surgery on somatosensory function and recovery pattern in the early postoperative period

“…The main type of injury might be nerve compression (15), which causes more damage to A-beta fibers than to A-delta or C fibers (3). These results are consistent with the findings of Park et al (16). Recently, Luo et al.…”

“…MDT was assessed using a standardized set of modified von Frey filaments (Optihair2-Set; Marstock Nervtest, Schriesheim, Germany) exerting forces between 0.25 and 512 mN. MPT was assessed using custom-made, weighted, pinprick stimuli with fixed stimulus intensities (8,16,32,64,128,256, and 512 mN; diameter of flat contact area, 0.2 mm; PinPrick; MRC Systems GmbH, Heidelberg, Germany). VDT was assessed with a Rydel-Seiffer tuning fork (64 Hz, 8/8 scale; example available at Arno Barthelmes & Co. GmbH, Tuttlingen, Germany) applied with suprathreshold vibration intensity.…”

The Current Perception Threshold Test Differentiates Categories of Mechanical Neck Disorder

“…However, the CPT method has been used to evaluate peripheral sensory dysfunction 28 been successfully applied in many clinical studies. 12,29,30,42,43,47,54 Despite emerging literature about the usefulness of CPT, there are limitations. For example, hyperesthetic, normative, and hypoesthetic values of rapid CPT are not yet well established, and the test threshold values can vary according to the location of the test.…”

“…The CPT test has been used successfully as a reliable and valid assessment in different clinical studies for sensory evaluation. 28,33,[40][41][42][43]47,52,54,56,74 The CPT test has been reported to be consistent across occasions (intertrial reliability, intraclass correlation coefficient [ICC] = 0.73-0.82; test-retest reliability, ICC = 0.47-0.86; P<.001) in patients with neck disorder, and the test threshold was associated with neck disability. 67 However, no study has evaluated its ability to discriminate subgroups of neck pain.…”

Clinical Predictors of Permanent Neuropathy in Patients with Peripheral Painful Traumatic Trigeminal Neuropathy

“…The Neurometer QST procedures were matched with another previous study that evaluated neurosensory alteration in orthognathicsurgeries. 7) Stimuli were delivered at 250 Hz to assess the sensory threshold associated with A-δ fiber stimulation, and at 2,000…”
