title: Microvasculature of the human fetal laryngeal anterior commissure.
abstract: The vascular pattern of the injected with Mercox human fetal larynges, especially of the anterior commissure and surrounding it area, was analysed within the horizontal and frontal sections under a light microscope. The main result of our study was confirmation of existence of the avascular "plane zero" situated above the anterior commissure, which separates that structure from the supraglottic tier. That finding i.e. avascular separation between teh middle and upper laryngeal compartments, already present in the fetal period, has clinical implications as far as the spread of neoplastic process within the larynx is cancerued.
