BACKGROUND: Management of the N0 neck in patients with head and neck squamous cell carcinoma (SCC) remains controversial. We describe the outcome of patients who underwent transoral tumor excision and a wait-and-see policy for the neck staged N0 by ultrasonography-guided cytology (USgFNAC). Because selection of lymph nodes for USgFNAC is currently based on size criteria, we investigated the additional value of sentinel node (SN) identification. METHODS: The outcome of 161 patients with T1-T2 oral/oropharyngeal SCC was determined. In a subgroup of 39 patients the SN was identified and aspirated in addition. RESULTS: SN identification and aspiration was possible in 38 of 39 patients but without decreasing the false-negative rate of USgFNAC. During follow-up (12-99 months) 34 of 161 (21%) patients developed lymph node metastases. After therapeutic neck dissection and postoperative radiotherapy, 27 of 34 (79%) could be salvaged (88% regional control). CONCLUSIONS: Wait-and-see seems justified in case of negative USgFNAC. Strict follow-up with USgFNAC is required. SN identification and aspiration is feasible but did not improve lymph node selection. Copyright 2002 Wiley Periodicals, Inc.
