Usefulness of Laryngoscopy and Computerized Tomography as Combined Diagnostic Modality for Accurate Diagnosis and Appropriate Treatment Selection in Laryngeal Malignancies
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 5
Abstract
Introduction: Cancer can develop in any part of the larynx, but the cure rate is affected by the location of the tumor. For the purposes of tumor staging, the larynx is divided into three anatomical regions: The glottis (true vocal cords, anterior, and posterior commissures); the supraglottis (epiglottis, arytenoids and aryepiglottic folds, and false cords); and the subglottis. Aim: The aim of the study is to study about the involvement of the pre-epiglottic and paraglottic spaces in tumors of larynx and to trace the extent of spread of tumour from one region to other regions. Materials and Methods: 30 cases were selected in which there was good clinicopathological correlation and growth patterns could be compared with computerized tomography (CT) findings. Results: 60% patients have pre-epiglottic space involvement seen in CT, which could not be found in laryngoscopic. True vocal cord involvements are picked up as same in both CT and laryngoscopic examination. Anterior commissure involvement is detected more in CT and is about 50%. Whereas in laryngoscopic examinations 23% were detectable. Conclusion: All cases of laryngeal malignancies combined CT and laryngoscopic examination should be taken for accurate diagnosis and appropriate treatment selection.
