Head and neck squamous cell carcinoma is the sixth most common malignant tumor in the world. Cervical lymph node metastasis is frequently encounted on the date of diagnosis. Surgical resection is one of the most important treatment methods for head and neck squamous cell carcinoma with or without lymph node metastasis. At present, for cN0 patients, prophylactic neck dissection is recommended for squamous cell carcinoma originating in suprglottic, hypopharyngeal and oropharyngeal areas et al. Related studies reported that less than 30% of patients with cN0 were confirmed to have lymph node metastasis in postoperative pathological examination, who underwent neck dissection. Unnecessary neck dissection may increase complication incidence, such as neurovascular injury, chylous leakage, sialosyrinx. Accurate preoperative assessment is helpful to reduce unnecessary neck dissection. Sentinel lymph node biopsy were proved to be effective in reducing prophylactic lymph node dissection in breast cancer, melanoma and other malignant tumors. Compared with γ probe detection and indolyanine green injection, microbubble and contrast-enhanced ultrasound has no radiation and disturbance to resection margins in sentinel lymph nodes detection. Furthermore, surgeons could conduct lymph node puncture biopsy simultaneously under ultrasound guidance, which can further minimize surgical trauma. At present, the role of microbubble and contrast-enhanced ultrasound in sentinel lymph node detection and biopsy is rarely reported in head and neck squamous cell carcinoma. This study aims to explore the accuracy of peritumoral microbubbles and contrast-enhanced ultrasound for sentinel lymph nodes biopsy in predicting cervical lymph node metastasis in head and neck squamous cell carcinoma.
