Surgical outcomes of cutaneous squamous cell carcinoma in the head and neck: analysis of resection margins, recurrences, and metastasis

Tumor depth was identified as the main determinant for achieving complete tumor resection, underscoring its prognostic relevance in cSCC. The low incidence of synchronous and metachronous lymph node metastases highlights the favorable local control achievable with adequate surgical margins and regular follow-up. The study further emphasizes the importance of early detection and structured surveillance, including regular head and neck ultrasonography, for the timely identification of metastatic disease and optimized patient management.
