The main purpose of this research was to do an intraindividual comparison of outcomes between the open ulnar incision (OUI) and the Paine retinaculotome with palmar incision (PRWPI) techniques in patients with bilateral carpal tunnel syndrome (CTS). The patients underwent OUI surgery on one hand and PRWPI surgery on the contralateral hand. The patients were evaluated with the Boston carpal tunnel questionnaire, visual analogue scale for pain, palmar grip strength, and fingertip, key, and tripod pinch strengths. Both hands were examined in the preoperative and postoperative periods after 2 weeks, 1 month, and 3 and 6 months. Eighteen patients (36 hands) were evaluated. The symptoms severity scale (SSS) scores were higher, in the preoperative period, in the hands that underwent surgery with PRWPI ( -value = 0,023), but lower in the 3rd month postoperative ( -value = 0.030). The functional status scale (FSS) scores were lower in the periods of 2 weeks, 3 months, and 6 months ( -value = 0,016) on the hands that underwent surgery with PRWPI. In a different two-group module study, the PRWPI group presents the SSS scores average on the 2nd week and 1st month, and the FSS scores average on the 2nd week, less 0.8 and 1.2 points respectively comported to open group. The hands that underwent surgery with PRWPI presented significantly lower SSS scores at 3 months postoperative, and lower FSS scores at 2 weeks, and 3 and 6 months postoperative, compared to open surgery group.
