RESUMEN
Background: The inaccuracies in clinical examination have been well-documented while advanced imaging modalities including computed tomography (CT) and magnetic resonance imaging (MRI) have been shown to have superior diagnostic accuracy in detecting occult and nodal metastasis. The aim of the present study was to identify as well as evaluate the inaccuracies in clinical examination and of clinical diagnostic criteria in known cases of oral squamous cell carcinomas (OSCCs) with the help of MRI. Methodology: A total of 24 patients attending as outpatients were included in the study while clinically diagnosed and histopathologically proven cases of OSCC were examined clinically and then, subjected to advanced imaging with the help of MRI. Statistical Analysis Used: Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 17.0 (SPSS Inc., Chicago, IL, USA) while paired t-test was performed for evaluating size of tumor and lymph node recorded on clinical and imaging findings. p<0.05 was considered statistically significant. Results: Detection of tumor size and lymph node metastasis were found to be higher in case of MRI than when accomplished by clinical staging alone while paired t-test values for difference in results were found to be statistically significant (p<0.05). Conclusions: The present study showed that clinical diagnostic criteria alone were not sufficient and reliable for detecting metastatic lymphadenopathy highlighting the significance of advanced imaging modalities like MRI for an efficient pre-operative diagnostic work-up as well as, as a tool for planning treatment in patients with OSCCs.
