Introduction: This study aims to investigate the Carpal Tunnel Syndrome (CTS) levels of the patients predi-agnosed with CTS by electromyography (EMG) by using the scanning model.

Materials and methods: The study included thirty-two wrists of 22 patients with positive elec-tromyography examination with a preliminary CTS diagnosis. Cases with previous trauma, sur-gery, steroid injection involving the wrist region, and cases who reported systemic diseases such as uncontrolled diabetes, gout, and kidney failure were excluded from the study. In the study, ultrasound measurements of the control and patient groups were compared.

Results: Of the 22 patients aged 31-71 included in our study, 4 (18%) were male, and 18 (82%) were female. The analysis of the research data revealed significant differences between the patient and control groups in terms of the mean area of the median nerve in the carpal tunnel, the mean anteroposterior diameter, mean transverse diameter, the anteroposterior diameter of the median nerve in the distal forearm, and the mean anteroposterior diameter ratio at the level of the carpal tunnel.

Conclusion: The ultrasonography measurements in patients diagnosed with CTS by clinical examination and electrodiagnostic examination are significant in terms of revealing the findings related to the damage of the median nerve and the anatomical differences.
