Does the tumor thickness value of buccal squamous cell carcinomas, predict cervical nodal metastasis in clinically and radio-graphical neck negative (N0) thus sparing such patients unnecessary surgical procedures and it's associated morbidities? The aim of the study is to evaluate the prognostic value of tumor thickness cut off 4 mm in predicting cervical nodal metastases in a population of Egyptian patients presenting with Buccal Squamous Cell Carcinoma. The hypothesis is that patients with tumor thickness less than 4 mm will present with significantly less cervical nodal metastasis.
