The accuracy of clinical neurosensory testing for nerve injury diagnosis

摘要: Purpose: The accuracy of the clinical neurosensory test to diagnose trigeminal nerve injuries has never been statistically evaluated. purpose this study was determine statistical efficacy using surgical findings as “gold” standard, and whether a correlation existed between sensory impairment score obtained by preoperative testing degree injury found at surgery. Materials Methods: A multisite, randomized, prospective, blinded, trial conducted on 130 patients with inferior alveolar (IAN) lingual (LN) injuries. Preoperatively, were provided three-level drop-out (NST), blind comparisons made postoperatively. Results: positive predictive negative values for LN-injured 95% 100%, respectively. IAN 77% 60%, There significant differences in distribution age, duration injury, cause presence neuropathic pain, trigger LN patient populations. relationship injury. Conclusions: NST is clinically useful method However, results are less efficient than injuries, have high incidence false-positive (23%) false-negative (40%) when different rates efficiency two groups may be attributable prevalence biologic covariates.
