Aims & objectives:– 

1)    To evaluate the sensitivity and specificity of detecting neoplastic cartilage invasion in laryngeal cancer patients with the use of spiral CT

2)    To evaluate if CT findings influenced the management and treatment planning in patients with ca larynx  

Materials and Methods:–

              This is a prospective conducted at Tertiary care centre, from July 2016  to October 2018 involving 40 patients, in whom mass lesion is seen on indirect laryngoscope & FNAC/ Biopsy proves it to be a case of carcinoma larynx. Equipment used during study was–Siemens Dual slice Helical Somatom Emotion Duo CT scanner  using multidetector CT with two slice spiral CT scanner, Somatom, Siemens (Germany)

Result :–  

1)    The CT can predict the cartilage invasion when combination of more than one criterion is used.

2)    CT helped in changing the management in significant number of laryngeal cancer patients.
