Carpal tunnel syndrome is the most common tapped nerve entrapment neuropathy. Conservative and surgical treatment options are avaliable for carpal tunnel syndrome. Wilson`s double incision and Bromley`s mini incision techniques are the most prefered surgical techniques. Recurrent carpal tunnel syndrome is defined as: reoccurence of the complaints which are regressed after surgery but reoccured in long term follow-up. Most common cause of the failure after surgery is insufficient release of transvers carpal ligament. Conservative treatment is not efficient for patients with recurrent carpal tunnel syndrome. Also isolated neurolysis and carpal tunnel decompression are not efficient enough. In revision surgery synovial flaps, muscle flaps and autologous fat transfers could be applied. We prefer `Hypotenar Fat Pad Flap` in these cases.
