Article Abstract
Hearing loss is one of the most common health problems and there is no suitable way to regenerate up to now. However, if the mechanism can be clearly clarified, physiological auditory regeneration may be a possibility. Organoids, artificially generated by pluripotent stem cells under three-dimensional (3D) culture system, are now considered attractive options for constructing different 3D models to study auditory regeneration and the potential mechanisms in vitro. Organoids are essentially miniature 3D models of specific organs or tissues, enabling scientists to investigate the causes of diseases, test new drugs, and explore personalized medicine within a controlled laboratory setting. Recent discoveries have demonstrated that stem cell-derived organoids can mimic environments in vivo and provide invaluable information for modeling cochlea micro-environment. In this paper, we will provide an overview of the progress achieved in inner ear organoids as a preclinical model, aiding our understanding and providing a more effective approach to addressing hearing loss.

Intratympanic (IT) delivery of dexamethasone (DEX) is widely used for treating inner ear disorders; however, its therapeutic efficacy is limited by poor permeability of the round window membrane (RWM). This study aimed to evaluate and compare the efficacy and safety of three pharmacological agents-histamine (HIS), 3% hypertonic saline (3% HS), and sodium caprate (SC)-as adjuvants for enhancing RWM permeability and improving IT-DEX delivery in a murine model. Following IT administration of each permeability enhancer followed by DEX injection, perilymph DEX concentrations were measured using ultra-high-performance liquid chromatography, and DEX receptor expression in the organ of Corti was assessed by immunofluorescence.

Sudden sensorineural hearing loss (SSNHL) is an acute hearing disorder that develops rapidly and is an otolaryngology emergency. Hyperbaric oxygen therapy (HBOT), a non‑pharmacological treatment, has gained increasing attention for SSNHL management. HBOT exerts therapeutic effects by increasing inner ear oxygen partial pressure, improving the microcirculation and reducing inflammation, as its main mechanisms.

Cardiospondylocarpofacial syndrome (CSCFS) is an extremely rare autosomal dominant disorder resulting from variant in the gene, which encodes the transforming growth factor-β-activated kinase 1 (TAK1). Only 26 cases of CSCFS have been reported worldwide. The main manifestations are growth retardation, hypotonia, dysmorphic facial features, skeletal and limb abnormalities, cardiac septal defects with valve dysplasia, cardiomyopathy, and deafness with inner ear malformations.

The plasma membrane is actively regulated by lipid transporters that create electrochemical gradients between leaflets, and passively by scramblases that dissipate these gradients. Membrane properties such as lipid packing are critical for the proper function of transmembrane proteins, particularly mechanosensitive ion channels. Mechanosensation is a key component of many sensory processes including balance, and hearing.
