Vasculature of the Crista ampullaris of the Rat as Seen in Microcorrosion Casts

Abstract: A scanning electron microscope study of corrosion cast preparations of the vessels of the crista ampullaris was carried out in adult rats. This method shows the microvasculature of the cristae in the three-dimensional model. As a result of this technique we have been able to demonstrate on microscopical level a particular microvasculature in the septum cruciatum of the crista in rat.

A scanning electron microscope study of corrosion cast preparations of the vessels of the saccule was carried out in adult rats. This method shows the microvasculature of the saccule in the three-dimensional model. As a result of this technique we have been able to demonstrate a particular microvasculature of the saccule in the rat's inner ear. The main blood supply of the saccule consists of the arterioles coming from the vestibulocochlear artery entering the anterior margin of the macula sacculi. A few branches of the anterior vestibular artery enter the macula sacculi from the superior margin. The saccular vein drains the venous blood from a dense capillary area underneath the striola to the posterior vestibular vein which eventually ends in the vein of the cochlear aqueduct.

Vascular Inner Ear Partition:A Concept for Some Forms of Sensorineural Hearing Loss and Vertigo

The results of a series of scanning electron microscopical studies were used to construct a model for the vascular pathways in the inner ear. Corrosion cast preparations of the vessels of the inner ear of the adult rat were used in this study. The inner ear is, like a hand, an end organ containing four sense organs (cochlea, saccule, utricle and the cristae ampullaris). All these specific inner ear structures have their own vascular supply. We have developed a blood flow diagram of the inner ear. This model was used for a classification of different types of ischemia in the inner ear and forms a concept for some forms of sensorineural hearing loss and vertigo. Four types of inner ear ischemia are proposed. In type I (a or b) of inner ear ischemia only the vessels of the cochlea are involved resulting in two types of hearing loss without vertigo. Type II is characterized by ischemia of a part of the cochlea and a part of the vestibular system. In type III (a or b) only the vestibular system is involved, while in type IV no blood circulation will be present in the inner ear resulting in total deafness and severe vertigo. Inner ear partition at ultramicroscopical level of these structures may be possible in the future and new imaging techniques will probably support the vascular schematic model presented in this study.
