Preoperative staging protocol included indirect laryngoscopy, direct microlaryngoscopy and contrast enhanced CT scan. The histologic findings were compared with the clinical findings and the CT scan MR images. The impact of each diagnostic method on pretherapeutic staging was analyzed.<o:p></o:p></span></p> <p class="MsoNormal"><b><span lang="EN-IN" style="font-family:&quot;Times New Roman&quot;,serif">RESULTS<o:p></o:p></span></b></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:normal"><span lang="EN-IN" style="font-size:12.0pt;&#10;font-family:&quot;Times New Roman&quot;,serif">The CT staging of laryngeal carcinoma showed very high accuracy in staging subglottic and supraglottic tumours (100%), (77.7%) respectively in comparison to clinical staging and lower accuracy (66.66%) in staging glottic tumours. Underestimation of all tumours was 15% &nbsp;of cases (especially small and superficial lesions).<o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"><b><span lang="EN-IN" style="font-family:&quot;Times New Roman&quot;,serif">&nbsp;</span></b></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"><b><span lang="EN-IN" style="font-family:&quot;Times New Roman&quot;,serif">CONCLUSION<o:p></o:p></span></b></p> <p class="MsoNormal"><span lang="EN-IN" style="font-size:12.0pt;line-height:115%;&#10;font-family:&quot;Times New Roman&quot;,serif">The accuracy of clinical staging decreased from glottic to supraglottic to subglottic tumours. Conversely, the staging accuracy of sectional imaging is best in subglottic tumours and supraglottic tumours and lower in glottic tumours.<o:p></o:p></span></p> <p class="MsoNormal" style="text-align:justify"><span lang="EN-IN" style="font-size:14.0pt;line-height:115%;font-family:&quot;Times New Roman&quot;,serif">&nbsp;</span></p>
