Giant Cell Tumor of the Tendon Sheath (GCTTS), often manifested as a nodular mass in the hand, presents significant challenges for surgical intervention, particularly when located in the fingers. This study aimed to evaluate the impact of GCTTS excision on sensory function and to explore the relationship between surgical outcomes and factors such as smoking and nerve dissection. A retrospective analysis was conducted on 28 patients diagnosed with GCTTS in the fingers, who underwent surgical excision between March 2017 and March 2023. Preoperative and postoperative sensory functions were assessed using two-point discrimination and Semmes-Weinstein monofilament tests. The results indicated no significant difference in sensory function 6 months post-surgery, suggesting that meticulous surgical technique can mitigate the risk of iatrogenic nerve damage. The study highlights the importance of comprehensive diagnostic methodologies, including thorough medical history, physical examination, and radiological imaging, in guiding surgical strategies. Moreover, it emphasizes the significance of meticulous preoperative planning and the potential for preserving sensory function following GCTTS excision.
