Popis: Abstract Background Reconstruction of soft tissue defects following surgical tumor resection is important for quality of life in cancer patients with oral and oropharyngeal squamous cell carcinoma (SCC). This study presents a novel computer-aided reconstruction of soft tissue (CARST) technology employed with these patients. Methods We first described the CARST technology in detail in a report of a 34-year-old male patient with locally invasive right-sided tongue SCC following a nearly total glossectomy and reported the postoperative outcomes. This digital technology was applied to construct a 3D model from CT images, which was used to delineate surgical resection boundaries and design a personalized reconstruction of the soft tissue defect. A nonuniform rational B-spline (NURBS) was generated and applied to transform the 3D model into a 2D flap-cutting guide printed out using a 3D printer. We then reported a case-series study on oral and oropharyngeal SCC patients who were randomly assigned to receive the CARST (n = 15) or a traditional soft tissue reconstruction (n = 15). Clinicopathological features and short- and long-term postoperative outcomes between the two groups were compared. Results The patient with the tongue SCC had a successful CARST following surgical tumor resection without any complications. His speech and swallowing functions recovered well after surgery and he experienced no significant changes to his appearance following recovery. There was no recurrence within a 3-year follow-up period. Results of the case-series study showed that the CARST group had significantly shorter operative and post-operation hospital-stay time, a higher flap utilization rate, and a trend of less and milder postoperative complications, and they experienced no significant difference in intraoperative blood loss and long-term outcomes compared to the traditional group. Conclusion CARST is a safer and more efficient personalized technology of soft tissue reconstruction following surgical tumor resection in patients with oral and oropharyngeal SCC.
