Round window vibroplasty: Long-term results
Acta Oto-Laryngologica, 2012The round window (RW) approach in the use of the Vibrant Soundbridge(®) (VSB) is a safe and effective treatment of conductive and mixed hearing losses for a period of more than 3 years of device use.To investigate the long-term safety and efficacy as well as user satisfaction of patients with conductive and mixed hearing losses implanted with the VSB ...

The Journal of otolaryngology, 1977
Round window fistula as a cause of sudden hearing loss was diagnosed in five people. It was associated with a sudden change in middle ear pressure in three, with heavy lifing in one, and was probably caused by a significant blast exposure in the other.

The Normal Chinchilla Round Window Membrane
Archives of Otolaryngology - Head and Neck Surgery, 1982The chinchilla round window membrane consists of three layers: (1) an outer epithelial layer facing the middle ear cavity with tight junctions and numerous desmosomes, (2) a middle connective-tissue layer consisting of fibroblasts, fibrocytes, collagen, elastin, capillaries, and myelinated and unmyelinated nerves, and (3) an inner cellular layer with ...

Experimentally Induced Round Window Membrane Lesions
Acta Oto-Laryngologica, 1977This investigation confirmed previous studies indicating that the middle and inner ear of the guinea pig have a pronounced tendency to healing. Middle ear hemorrhage of surgical origin appears to stop quickly in the guinea pig. A surgically created perforation of the round window with or without removal of perilymphatic fluid by suction resulted in a ...

Endotoxin Permeability through the Round Window
Acta Oto-Laryngologica, 1988The permeability of the round window membrane to Salmonella typhimurium derived endotoxin was examined using a total of 17 chinchillas. One mg of endotoxin was instilled into the tympanic cavity via the superior bulla. Endotoxin activity in middle ear effusions (MEEs), perilymph (both inoculated and non-inoculated side), and sera was determined by ...

Rupture of the round Window Membrane
Annals of Otology, Rhinology & Laryngology, 1976A case of sudden deafness due to rupture of the round window membrane is presented. Nineteen similar cases have previously been reported in the literature. In a review of these twenty patients, it is noted that a history of concurrent physical effort or barotrauma was present in eighteen.

The round Window Membrane: Otological Observations
Annals of Otology, Rhinology & Laryngology, 1983The membrane of the round window serves as a barrier between the middle and inner ear and has a well-established role in cochlear physiology. It is important in many otological conditions; otitis media, otosclerosis, trauma, sequelae to drugs reaching the middle ear, tumors, congenital dysplasia, sudden deafness.

Endoscope-guided Round Window Fistula Repair
Otology & Neurotology, 2001Endoscope-guided round window membrane repair was performed to evaluate whether the approach is feasible in the treatment of a round window fistula.Retrospective case review.Tertiary care academic center.A 27-year-old man had been scuba diving 6 days previously in the Australian Great Barrier Reefs. He had poor hearing with tinnitus in the left ear and

Blood flow of the round window
Archives of Oto-Rhino-Laryngology, 1981Motion pictures of the blood flow of the round window in guinea pigs were taken. In this part the blood flow of the inner ear could be distinguished from that of the middle ear. Our motion pictures show that the blood flow of the inner ear can be observed through the round window membrane without an operation on the inner ear.

Permeability of the round window membrane
Archives of oto-rhino-laryngology, 1984Cefmetazole sodium, a cephamycin antibiotic, was shown to pass through the round window membrane into the inner ear of the guinea pig. The concentration of the drug in the inner ear fluid indicated that a larger amount of the drug reached the inner ear through the round window membrane than when administered intraperitoneally.
