Purpose
The oral squamous cell carcinoma is one of the rapidly growing oral cancers and is the 6th most common cancers in the world. Squamous cell carcinoma of lower gingivo-buccal complex and tongue are most common cancers in the Indian sub-continent.
The choice of appropriate treatment for patients with oral cancer depends largely on accurate pre-treatment staging.
The value of imaging in the staging of oral cancers is in judging operability, assessment of the prognostic characteristics and dimensions of the primary tumour, depth of tumour invasion and the presence of lymphadenopathy.
Excellent soft-tissue discrimination of MRI readily reveals tumour invasion and spread to surrounding structures and is a very useful tool for providing the details of structures within the oral cavity.
AIMS AND OBJECTIVES:
1)To assess the relationship between the depth of invasion and the occurrence of cervical lymph node metastasis.
2)To assess the diagnostic accuracy of MRI in predicting depth of tumour invasion in oral cancers and to correlate it with histopathology.
3)To emphasize the importance of MR Imaging as a valuable tool for carrying out the loco-regional staging of oral cavity cancers with an extreme degree of precession.
