SN mapping was feasible in patients with non-parotid salivary gland tumors, with a high detection rate using SPECT-CT. SN distribution was primarily ipsilateral but bilateral in two patients with minor salivary gland tumors. Identification of SN micrometastases highlights the potential of SLNB to improve staging accuracy. Our findings support further investigation of the SN technique as a diagnostic tool in the management of cN0 neck in this rare tumor group.
