Head and neck squamous cell carcinoma: US-guided fine-needle aspiration of sentinel lymph nodes for improved staging--initial experience.
Ultrasonography (US)-guided fine-needle aspiration with cytologic examination was combined with lymphoscintigraphy for the identification of sentinel lymph nodes (SLNs) in 12 patients with a squamous cell carcinoma of the oral cavity or oropharynx. Dynamic lymphoscintigraphy and a hand-held gamma probe were used to depict the SLNs to be aspirated. Cytologic examination of the aspirated SLNs revealed neck lymph node status in patients who underwent neck dissection (n = 6). In patients who underwent only transoral excision, one false-negative cytologic result was observed. This combined approach is expected to improve the detection of occult neck lymph node metastases.
