The mini incision technique for carpal tunnel decompression using nasal instruments.

AIM Mini incision techniques for carpal tunnel release have become increasingly popular for the treatment of carpal tunnel syndrome. The main advantages of mini incision techniques are shorter recovery and return-to-work time. However, the risk of neurovascular injury still remains worrisome. We present a novel method to release the carpal tunnel by using nasal instruments. This novel technique combines the advantages of endoscopic and open techniques while utilizing standard instruments. The advantages, disadvantages and results of this technique are discussed. MATERIAL AND METHODS Forty-five patients (15 male, 30 female, age 28-62; mean 48) with isolated carpal tunnel syndrome were enrolled to the study. Atotal of 55 wrists (bilateral in 7 cases, the right wrist in 41 and the left wrist in 14) underwent carpal tunnel decompression with a mini longitudinal incision technique. Grip strength--key pinch and sensorial evaluations were performed in all patients by one examiner using the Pressure-Specified Sensory Device. RESULTS Significant differences between the pre- and postoperative periods were observed in either grip strength or pinch strength (p<0.05). No recurrence or injury to the neurovascular structures was noted in the follow-up period. CONCLUSION The technique is simple and effective, employs inexpensive instruments, and has a low complication rate.
