Abstract

Squamous cell carcinoma comprises 95% of laryngeal carcinomas. It is usually detected by laryngoscopic evaluation. Imaging plays an important role in the evaluation of submucosal extension and staging of this malignancy. Supraglottic, glottic and sublottic regions are separately evaluated. In supraglottic region extension of the mass to preepilottic and paraglottic spaces and cartilges invasion are assssed. Bilateral TVCs and anterior commissure are evaluated in the glottic region and cricoid ring is scrutinized in subglottic area. Complete evaluation of cervical lymph nodes and distant metastasis are the next step. Hypopharyngeal SCC can involve pyriform sinus, post-cricoid and posterior pharyngeal walls. These must be differentiated from laryngeal carcinoma extension.
