Endoscopy and cross-sectional imaging are considered indispensible for evaluation of larynx and oral cavity.USG is undoubtedly a powerful investigative tool in head and neck pathologies. Larynx and tongue are no exception. But, when compared to crosssectional imaging where USG does stand is the question raised and answered in this paper. It is important to follow a systematic USG technique to evaluate the larynx and the tongue. USG has accuracy of 71.4% while CT had 92.8% accuracy in assessing cancer of hypopharynx. USG has accuracy of 61%, while MRI has accuracy of 91% in assessing tongue cancer. Post cricoid extension and small PFS growth are not appreciable on USG in cases of larynx cancers, where as small intrinsic tongue muscle growths and alveolar involvement were not seen on USG in cases of tongue malignancy.USG can easily visualize vocal cord movements, pre-epiglottic space lesions and sub-mandibular duct involvement, which are relatively difficult to appreciate on cross-sectional imaging. Even though small tumors are difficult to visualize, USG can play a significant role in assessment of the tumor extension inside and outside the organ. Especially when cross-sectional imaging is unavailable, unaffordable, contraindicated and in post treatment follow up cases.
