AB  - PURPOSE: To investigate the efficacy of sagittal ultrasonography of the median 
      nerve in diagnosing carpal tunnel syndrome (CTS). METHODS: Seventy-six hands with 
      idiopathic CTS and 80 hands of asymptomatic subjects were included. All patients 
      with CTS underwent ultrasonographic examination, electrodiagnostic testing, and 
      CTS-6 assessment. In the sagittal ultrasonographic examination, the maximum and 
      minimum median nerve diameters (MNDs) were measured at the proximal and distal 
      ends of the carpal tunnel, respectively. The median nerve stenosis rate (MNSR) 
      was computed as (1 - minimum MND/maximum MND) x 100 (%). The cross-sectional area 
      (CSA) of the median nerve at the level of the pisiform was measured. RESULTS: In 
      the sagittal ultrasonographic examination, the mean maximum MNDs were 0.252 cm 
      and 0.202 cm, mean minimum MNDs were 0.145 cm and 0.165 cm, and mean MNSRs were 
      41.83% and 17.35% in the CTS and control groups, respectively; the mean maximum 
      MND and MNSR were considerably larger in the CTS group. The maximum MND and MNSR 
      were correlated with the electrodiagnostic testing results and CTS-6 score. The 
      MNSR with a cut-off value of 34.0% had a higher sensitivity and specificity than 
      the CSA in diagnosing CTS. CONCLUSIONS: Sagittal ultrasonographic examination is 
      useful in diagnosing CTS.
