1. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology
Abstract : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. READ MORE

2. Middle ear mechanics : using temporal bone experiments to improve clinical methods
Abstract : BackgroundThe middle ear transmits and amplifies sound vibrations from the tympanic membrane via three ossicles to the inner ear. Moreover, it contains two muscles, the stapedius muscle (SM) which protects the inner ear from loud noise, and the tensor tympani (TT) whose function is still debated. READ MORE

3. On Pressure Regulation of the Middle Ear
Abstract : The middle ear (ME) pressure is regulated by gas diffusion over the ME mucosa and pressure equalizations via the Eustachian tube (ET). Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. READ MORE

4. Pitch, loudness and frequency selectivity in low-frequency hearing loss
Abstract : Patients with Ménière's disease and cochlear hydrops show fluctuating low-frequency hearing loss (FLFHL). At present these changes are followed as patients' subjective reports and occasional measurements. READ MORE

5. Fibroblast Contractility in vivo and in vitro : Effects of Prostaglandins and Potential Role for Inner Ear Fluid Homeostasis
Abstract : Fibroblasts continuously strive to organize and compact the surrounding extracellular matrix (ECM). Recent data suggest that this cellular contractility controls interstitial fluid homeostasis in loose connective tissues (CT). READ MORE
