The intricate physiological structure of the inner ear presents challenges for traditional medication treatment strategies, including systemic adverse responses, trouble penetrating the blood–labyrinth barrier, and low local cochlear concentration, resulting in poor therapeutic outcomes. An intriguing tactic that is extensively developed over decades is utilizing drug delivery systems to transport medication molecules to the inner ear. Herein, the challenges associated with inner ear delivery are discussed, cutting‐edge achievements in inner ear drug delivery systems are emphasized, including nano‐, micro‐, and macrocarriers, and finally opportunities to leverage advanced technologies to improve existing drug delivery strategies are highlighted.
