Abstract:
The number of people with hearing loss disorders is enormous, causing great physical and mental stress to patients, as well as a huge social burden. Among these patients, hearing loss caused by inner ear lesions accounts for a large proportion. Therefore, treatment of the inner ear is important. Inner ear drug delivery systems, which can reduce the side effects of systemic drug administration by delivering drugs directly to the inner ear, are important in sensorineural hearing loss. Here, the development of inner ear drug delivery systems is focused, including the complex physiological structure that they face, types of drugs delivered, routes of administration, and forms of drug delivery carrier platforms. Recent studies in this process are presented and it is concluded with a summary and outlook on the problems faced and possible solutions.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...
