2. Fig 1
Right wrist of a 49-year-old man diagnosed with CTS through electrodiagnosis. The proximal carpal tunnel, median nerve, and flexor tendon groups are shown between the pisiform and scaphoid bones. Proximal CSAs of the median nerve and carpal tunnel are shown at the scaphoid-pisiform level (A). Proximal CSAs of the median nerve and carpal tunnel were greater at the right side than the left side (B). (Right proximal CSA of the median nerve, left proximal CSA of the median nerve, right proximal CSA of the carpal tunnel, and left proximal CSA of the carpal tunnel were 14mm2, 10mm2, 224mm2, and 164mm2, respectively.)

3. Fig 2
Distal CSAs of the median nerve and carpal tunnel at the trapezium-hook of the hamate level. Distal CSAs of the median nerve and carpal tunnel were also greater at the right side (A) than the left side (B). (Right distal CSA of the median nerve, left distal CSA of the median nerve, right distal CSA of the carpal tunnel, and left proximal CSA of the carpal tunnel area were 14mm2, 10mm2, 188mm2, and 142mm2, respectively.)
