Eligibility Criteria
Inclusion Criteria:

The presence of symptoms such as nocturnal, posture-related, or movement-related paresthesias, along with possible pain, in the area supplied by the median nerve in the hand, lasting for more than 3 months.

Detailed Description
Carpal tunnel syndrome represents the most prevalent type of entrapment neuropathy. Anatomically, the carpal tunnel is formed by the carpal bones and lies beneath the transverse carpal ligament, housing nine tendon sheaths of the forearm flexors along with the median nerve. From a clinical perspective, individuals with carpal tunnel syndrome typically experience sensory symptoms such as paresthesia and hypoesthesia, as well as motor impairments and pain within the region supplied by the median nerve, all resulting from mechanical compression and localized ischemia.

In the classification of CTS, participants are diagnosed with mild, moderate, or severe CTS, and various treatment options are available for each category. Treatment options aimed at alleviating symptoms include physical therapy, splinting, wrist injections, and surgical procedures Ultrasound-guided injections of peripheral nerves are typically more advantageous than blind injections because minimize the risk of damaging crucial vascular structures in the adjacent tissue alongside the nerves and decrease the likelihood of intraneural injections.

CTS can also be treated surgically, although the literature has not provided sufficient evidence to establish the superiority of one surgical technique over another. However, these procedures are known to be effective by reducing the volume of the carpal tunnel, thereby relieving pressure on the median nerve. In CTS surgery, following a mini-incision, the dissection proceeds through fat and fascial tissue until the flexor retinaculum is reached, ensuring decompression of the median nerve. The advantages of the mini-incision technique include the preservation of neurovascular structures, a low risk of complications, and a high level of patient satisfaction, making it a prominent surgical approach.

The aim of this study is to compare ultrasound-guided perineural injection of the median nerve with the classic minimal incision surgical technique for median nerve decompression in participants diagnosed with mild, moderate, and severe carpal tunnel syndrome.
