How useful is intraoral ultrasound (US) in the determination of tumor dimensions and margin location of oral tongue carcinoma?
Background: The invasive nature of oral tongue carcinoma tumors into the underlying tongue musculature makes it difficult to assess the deep margin. Tumor thickness (TT) or depth of invasion (DOI) have been widely studied and closely correlate with locoregional recurrence rates and predict occult nodal metastasis. US has been seen as particularly useful in resolving the interface between tongue tumors and the surrounding myo-architecture at the deep margin.
