Round window vibroplasty in chronic ear surgery: comparison with conventional hearing rehabilitation
Acta Oto-Laryngologica, 2013Functional hearing results with round window vibroplasty in chronically disabled middle ears were comparable and, at high frequencies, superior to the results achieved with previously used conventional hearing aids even after extended surgery. Soft tissue transfer appears to be more important than floating mass transducer (FMT) alignment with the round

Inner Ear Decompression Sickness Combined with a Fistula of the round Window
Annals of Otology, Rhinology & Laryngology, 1990Inner ear barotrauma with rupture of the round or oval window secondary to diving and decompression sickness (DCS) of the inner ear can be a difficult diagnosis to differentiate. The dive profile or associated elements of DCS will often confirm the diagnosis. Occasionally, diagnosis is made during recompression or during operation.

Hearing Research, 2010
Mechanical stimulation of the round window (RW) with an active middle ear prosthesis (AMEP) has shown functional benefit in clinical reports in patients with mixed hearing loss (MHL). Further objective physiological data on the efficacy of RW stimulation is needed, however, to demonstrate that RW stimulation with an AMEP can generate input to the inner

Experimental Round Window Rupture with Middle Ear Effusion
Acta Oto-Laryngologica, 1983The effects of laceration of the round window membrane were investigated using the auditory brainstem response in guinea pigs with or without middle ear effusion. Sensorineural hearing impairment occurred in the lower basal turn of the cochlea with middle ear effusion.

Oval window absence, bony closure of round window, and inner ear anomaly
The Laryngoscope, 1974AbstractUnusual temporal bone findings are presented in a seven‐and‐one‐half‐year‐old female with marked hearing impairment and multiple congenital anomalies. The oval window was absent bilaterally, with no stapedio‐vestibular joint development on the right side and incomplete development on the left side. The round window membranes were normal, but on

Rupture of the Round Window Membrane in Inner Ear Barotrauma
Archives of Otolaryngology - Head and Neck Surgery, 1974Two cases of rupture of the round window membrane resulted from inner ear barotrauma. Both patients were experienced divers who had difficulty in autoinflation while diving. One suffered from increasing deafness over several days with mild vertigo; both ears were affected. The other had pronounced vertigo without any cochlear symptoms or signs.

Inner ear biocompatibility of lipid nanocapsules after round window membrane application
International Journal of Pharmaceutics, 2011Nanoparticle-mediated drug delivery represents the future in terms of treating inner ear diseases. Lipid core nanocapsules (LNCs), 50 nm in size, were shown to pass though the round window membrane (RWM) and reached the spiral ganglion cells and nerve fibers, among other cell types in the inner ear.

Oxygenation Through the Round Window Membrane and the Inner Ear Function
Auris Nasus Larynx, 1985The effect of oxygenation through the round window membrane was estimated using polarographic technique and the combined action potential of the inner ear. The calculated amount of oxygen permeable through the round window membrane (14% in room air and 80% in pure oxygen) revealed to have very limited effect in maintaining the inner ear potential ...

Acoustic stimulation on the round window for active middle ear implants
Computers in Biology and Medicine, 2018Many clinical reports have discussed the effectiveness of stimulating the ear's round window (RW) with a tool to mitigate conductive and mixed hearing loss. The RW is one of the two openings from the middle ear into the inner ear. Various methods have been proposed to construct a highly efficient, easily implanted, and reliable RW transducer.
