Intraoral ultrasonography with wrapped acoustic coupling medium

In patients with cancer of the tongue, the thickness and depth of the tumour are important independent prognostic factors for local recurrence, subclinical nodal metastasis, and survival.1–3 Intraoral ultrasonography is useful for assessing both factors,1–3 and intraoral colour Doppler sonography helps to predict delayed cervical lymph node metastases in early-stage cancer of the tongue.2 Without the use of echo jelly, direct contact of the probe with an oral lesion can lead to poor quality images, (and can also cause discomfort), and repeated use of the probe may transmit pathogens if it is not cleaned properly.
