Feasibility study of ultrasound-guided resection of tongue cancer with immediate specimen examination to improve margin control – Comparison with conventional treatment

•Feasibility study: ultrasound-guided tongue tumor resection in 10 patients.•Results are compared with a historical cohort of conventionally treated patients.•Amount of free margins achieved by ultrasound was significantly higher.•Mean overall margin distance achieved by ultrasound was not significantly higher.•Ultrasound-guided tongue tumor resections improves margin control. Squamous cell carcinoma of the tongue (SCCT) is preferably treated by surgery. Free resection margins (≥5 mm) provide local control and disease-free survival. However, close (1–5 mm) and positive margins (
