Title: L221 Infantile Cochlear Deafness Unilateral; Chapter: Infections; Chapter . Neuroepithelial Deafness - This type of congenital deafness occurs in newborn puppies regardless of coat patterns. Because the spontaneous cochleosaccular lesions described in dogs and humans are comparable, it has been proposed that dogs can serve as an animal model for the study of this type of deafness (Johnsson et al., 1973; Steel and Bock, 1983; Cable et al., 1994; Lalwany et al., 1997). These melanocytes are vital for strial survival [8-11], which in turn is required to maintain a suitable environment for cochlear hair cells [12]. Conclusions: This case report describes the auditory and histopathologic findings of a cat that showed an ASNR during BAER test despite the presence of cochleosaccular deafness. This connection between Objective: This study describes the histopathologic findings of a patient with severe bilateral sensorineural hearing loss after perinatal and postnatal hypoxia and asphyxia.

Hereditary deafness can be of either cochleosaccular or neuroepithelial origin. Hereditary deafness, also known as loss of hearing at birth, might occur in Frenchies with white coat pigmentation. Pigment-associated deafness can also be found in horses, cattle, pigs, and other animals. Division of Community Health Promotion.
The presence of the ASNR in dogs and cats with congenital profound deafness associated with white pigmentation is in contrast with a saccular origin of these potentials because these animals often have cochleosaccular degeneration [7-9].

Cochleosaccular deafness is a hereditary condition linked to pigment in a dog's coat and eyes. Conditions such as rubella can lead to maldevelopment of the organ of Corti that causes inner ear deafness. The hereditary deafness can be classified as cochleosaccular, neuroepithelial, or congenital in origin. The majority of genetic deafness targets the hearing organ-cochlea. Sampaio, Michael M.
