Abstract:With the development of cross nanotechnology and new medical materials, many nano medical materials have been derived and applied in clinical diseases. The multifunctional nanocomposite hydrogels (MNH) exhibit outstanding performance in many different aspects due to the polymerization of nanoparticles with different characteristics in the hydrogels. It has become one of the current research hotspots. Due to its excellent tissue compatibility and stability, it is particularly suitable in the field of otology research, such as drug delivery in the middle ear and inner ear, optimization of cochlear implant(CI) technology, and auricle tissue engineering. In recent years, many studies have successfully applied MNH to some key areas of otology and achieved good results. This paper will review the research status and application prospects of MNH in the field of otology.
