Ambidextrous Surgical Skills Training: What is Left to Do it Right?

Ambidextrous surgical skills may enhance efficiency and precision during complex procedures. However, their integration into surgical education remains limited. This study evaluates the feasibility and effectiveness of nondominant hand surgical training and its impact on skill acquisition and confidence among junior medical students.

A pilot randomized controlled trial (RCT) was conducted.

Participants attended structured suturing workshops involving demonstrations and supervised hands-on practice with their assigned hand (dominant or nondominant). Workshops were held at a university medical school, led by right- and left-handed surgical residents.

First- and second-year medical students with minimal suturing experience were randomized into 2 groups: NDom (nondominant hand training) and Dom (dominant hand training). Surgical skill performance was assessed pre- and postworkshop using a modified assessment rubric. Confidence levels and perceptions regarding ambidextrous surgical training were evaluated through questionnaires.

A total of 43 participants completed the study (NDom: n = 25; Dom: n = 18). Both groups demonstrated significant improvement in surgical skills (NDom: 1.2 ± 1.6-5.4 ± 2.1, p < 0.001; Dom: 1.8 ± 2.2 to 5.4 ± 1.3, p < 0.001), with no significant difference in skill acquisition between groups (p = 0.292). Notably, nondominant hand training also improved dominant hand skills (1.4 ± 1.9-5.0 ± 2.4, p < 0.001). Confidence in suturing skills and their application in the operating room increased significantly across both groups. Additionally, 97.7% of participants supported incorporating ambidextrous training into surgical education.

Ambidextrous surgical training is feasible and enhances surgical skills in both hands. Training the nondominant hand not only improves its dexterity but also strengthens dominant hand skills. Given the high level of participant support, integrating nondominant hand training into early medical curricula may optimize surgical proficiency and efficiency. Further research is needed to assess long-term outcomes.
