Vascular anomalies of the inner ear have been documented in only a few isolated case reports. The goal of our study was to describe, qualify and quantify vascular variations of the inner ear in 122 temporal bones from 64 pediatric subjects aged between 0 and 10 years. The average age was 11.6 months. Horizontal sections of the temporal bone, examined by light microscopy, revealed vessels coursing freely through the perilymphatic space of the cochlea, especially in the apical turn. Other findings included abnormally wide vessels in the stria vascularis as well as a vascular malformation of the internal auditory canal. Our study demonstrated more atypical vessels in the cochlea than in the vestibular labyrinth. We found a statistically significant positive correlation between vascular variations of the inner ear and concomitant cardiac anomalies or endolymphatic hydrops. We also discuss the possible etiology and potential significance of these findings in terms of disturbances of the function of the inner ear.

Even cochlear vascular anomalies and pathology in human Arterial vascularization of the human cochlea: historical aspects 13 scala tympani [41] and the human stria vascularis [42] could be demonstrated with the microdissection method with surface preparations [43].…”

The history of vascularization of the human cochlea began with the first anatomical description of the cochlea in the 16th century. Three different periods are recognizable in the development of knowledge concerning this subject: the macroscopic period, with the description of the structure of the cochlea from the 16th to the 19th century; the microscopic period, with the description of the part of the organ of Corti in the 19th century; and the injection period, with the description of the fine vascularization of the cochlea in the 20th century. Various techniques were used during these three periods, which will be presented here, using only original references. This historical study reveals the ingenuity of the researchers in using different aspects of technological progress to enhance their performance in research.

“…The fact that a sensorineural hearing loss often begins in the high-tone area suggests that the corresponding part of the cochlea, the basal turn, is also the most vulnerable part of the cochlea [10,11], Vascular anomalies can produce hearing loss and even tinnitus [12], Experimental work has proved that obstruction of the ar terial supply gives more severe and rapid damage to the inner ear than obstruction of the venous drainage [13].…”

This paper reports the results of a scanning electron microscopy study of corrosion cast preparation of the vessels in the cochlea of the rat. This method confirms the general findings about the cochlear vascularization, but also gives the opportunity to study the detailed pattern of the vascular supply of the stria vascularis in the round window area. The basal end of the stria vascularis has a remarkably different vascular anatomy compared with the other areas of the cochlea. The possible role of the vessels in the round area is discussed.
