The modiolar arteriole is a small blood vessel that supplies blood to the inner ear, specifically to the modiolus, a spiral structure within the cochlea. It is a branch of the labyrinthine artery, which itself is a branch of the internal carotid artery. The modiolar arteriole plays a crucial role in maintaining the blood supply to the sensory structures of the inner ear, including the spiral ganglion and the organ of Corti, which are essential for hearing and balance.

The modiolar arteriole is typically located in the modiolus, a bony structure that runs through the center of the cochlea. It provides a rich blood supply to the sensory structures, ensuring their proper functioning and preventing damage from ischemia. The modiolar arteriole is also involved in the regulation of fluid balance within the inner ear, as it helps to maintain the endolymphatic space, which is crucial for the transmission of sound waves into electrical signals.

The modiolar arteriole is a critical component of the inner ear's vascular system, and its proper functioning is essential for maintaining normal hearing and balance. Any disruption or damage to the modiolar arteriole can lead to hearing loss, tinnitus, and vertigo. Therefore, understanding the anatomy and physiology of the modiolar arteriole is important for the diagnosis and treatment of inner ear disorders.
