Sentinel lymph node biopsy in parotid gland carcinoma.

Indications for elective neck dissection (ELND) and its extent in N0-staged patients with parotid gland carcinoma are inconsistent. Therefore, a pilot study was performed to test the feasibility and efficacy of radioguided sentinel lymph node biopsy (SLNB) in these tumors. A total of 6 patients underwent lymphoscintigraphy, SLNB, and level II-IV ELND.
