ANATOMIC INVESTIGATION OF THE INTERNAL ACOUSTIC MEATUS VASCULARIZATION (Abstract): Knowledge of anatomical variants of the vasculo nervous elements of the internal acustic meatus helps to understand the pathophysiology of some patterns of hearing disturbances. The purpose of this study was to clarify the spacial relationship of the labyrinthine artery and the vascular loop of the anterior inferior cerebellar artery, based on the data issued from anatomical dissections under operating microscope on the colored gelatin injected specimens. All the specimens dissected presented a vascular loop formed by the anterior inferior cerebellar artery or the labyrinthine artery. The origin, number and trajects of the labyrinthine artery presents a wide variety, even in the case of the same individual (left right).
Key words: ANTERIOR INFERIOR CEREBELLAR ARTERY, LABYRINTHINE ARTERY, INTERNAL ACOUSTIC MEATUS, VASCULAR LOOP
