Abstract

Purpose: To evaluate the efficacy of minimally invasive particle implantation guided by different methods for head and neck malignancies based on propensity-matched score analysis.

Materials and methods: 120 patients with head and neck malignant tumors treated in our hospital from January 2021 to December 2023 were selected. The patients were matched by Propensity Score Matching (PSM) method at 1:1 and finally included in Computed Tomography (CT) guidance group (n = 60) and 3D print guide group (n = 60).

Results: The pain in the 3D print guide group was significantly lower than that in the CT guidance group at 3 days and 7 days after operation (P < 0.05). Preoperative tumor diameter, postoperative metastasis, and tissue edema were similar. However, the 3D printing guide group had smaller tumor diameters and fewer recurrences (P < 0.05). The 3D printing guide group also showed better curative effects and lower incidence of adverse reactions compared to the CT guidance group (P < 0.05), indicating its superiority in treatment safety and efficacy.

Conclusion: Minimally invasive particle implantation guided by a 3D-printed guide plate is safer and more effective than CT-guided treatment for head and neck malignancies.

Clinical trial number: Not applicable.
