Clinically node-negative oral squamous cell carcinoma poses a treatment challenge. Occult metastases occur in a significant number of patients. Surgeons traditionally perform elective neck dissection to address this risk.
Sentinel lymph node biopsy offers a less invasive alternative. It identifies the first draining lymph nodes. Surgeons then examine these nodes for cancer cells. A negative result allows them to avoid full neck dissection.
Researchers compare both approaches in early-stage tumours. They analyse detection rates of occult disease. Sentinel biopsy shows high sensitivity in selected patients. It reduces unnecessary surgery as a result.
Elective neck dissection remains the standard in many centres. It provides comprehensive staging. However, it increases surgical morbidity. Patients experience more shoulder dysfunction and longer recovery.
Furthermore, studies evaluate oncological outcomes. Both methods achieve similar regional control in T1 and T2 cases. Survival rates do not differ significantly. Quality of life improves with the biopsy approach.
The choice depends on tumour location and surgeon expertise. Floor-of-mouth lesions sometimes complicate sentinel mapping. Additional imaging and frozen-section analysis support accurate decisions.
Therefore, sentinel lymph node biopsy serves as a valid option in experienced hands. It minimises overtreatment. Elective dissection continues for higher-risk or technically difficult cases. Ongoing trials will further refine patient selection.
