Carcinoma Larynx:the Role of Ct Scan in Diagnosis and Staging (A Study of 50 Cases)

Laryngeal carcinoma accounts for 1% of all cancers 95% of all being squamous cell carcinoma. Modalities available for diagnosis and staging are clinical examination, direct and indirect scopy, biopsy and histopathological examination, CT and MRI.CT is the standard imaging modality for evaluation of carcinoma of larynx because of its easy availability, inherently high spatial resolution, faster acquisition time and recent advances like MDCT. AIMS AND OBJECTIVES:To determine accuracy of CT scan in diagnosing and detecting spread,cartilage invasion and lymphnodal metastases of laryngeal carcinoma and comparing it with histopathological findings. MATERIALS AND METHODS: A prospective observational study of 50 cases of either suspected or scopy/biopsy proven laryngeal carcinoma were evaluated with CT scan and the findings were than compared with per-operative or histopathological findings. CONCLUSION:Cross sectional imaging like CT is important and most widely used modality to delineate the extent of primary ,nodal spread and to evaluate deeper structures especially in endoscopically proven neoplasms with easy availability and affordability.
