Sentinel node biopsy for primary salivary gland tumours; feasibility study of a new technique

Introduction/Aims: There is no consensus on management of the N0 neck in patients with primary salivary neoplasms. Lymphatic drainage of the salivary glands is not well understood and elective neck dissection may miss the at risk lymph nodes. Sentinel node biopsy (SNB) is an accurate staging tool in other solid tumours but has not been widely described in salivary gland disease. We show that lymphatic drainage from primary salivary malignancy can be accurately mapped using a combination of SPECT/CT and navigational surgery.
