Posterior glottic pathology.

In infants and children, pathology in the posterior glottis is usually congenital or acquired due to endotracheal intubation. Diagnostic errors and omissions are less likely to occur with an anaesthetic technique where no endotracheal tube is used, where the posterior commissure and arytenoids are deliberately separated by a laryngoscope and where movements of the vocal cords and arytenoids are carefully assessed.
