Active middle ear implants (AMEIs) are medical devices intended to treat hearing loss by stimulation of the middle and inner ear structures. This study investigated the use of the Vibrant Soundbridge (VSB) (MED-
It is important to retract the fat slightly to prevent the edges of the perforation from growing inward to the middle ear and to avoid the formation of a cholesteatoma. The success rate is similar to paper patch but inferior to more formal tympanoplasty; moreover, it is dependent on the ...
Further study is required to validate these results in broader groups and investigate long-term consequences.Yousef, Medhat F.Audiovestibular Unit, Otolaryngology Department, College of Medicine, Menoufia University, Shibin El Koum, EgyptHajr, Eman...
Basically, the implanted portion is attached to one of the ossicles in the middle ear and drives the ossicles directly to deliver sound to the cochlea. Currently, Vibrant Soundbridge (MED-EL Corp.), Esteem middle ear implants (Envoy Medical), Maxum hearing implant (Ototronix LLC), and ...
Based on a histopathologic and immunohistochemical study of 48 cases, Torske et al[11] suggested using "neuroendocrine adenoma of the middle ear" as a more descriptive term, for it not only reflects its dual nature but also its benign clinical behavior. Moreover, they propose an undifferentiated...

Today, the standard method to predict output levels of active middle ear implants (AMEIs) before clinical data are available is stapes vibration measurement in human cadaveric ears, according to ASTM standard F2504-05. Although this procedure is well established, the validity of the predicted outpu...

for implantation in the middle ear, such as low noise charge to voltage amplification, bio-compatibility and low form factor packaging. Experiments in temporal bones should be performed, and finallyin vivotests ought to be successful and prove the functionality of the device in the long term. ...
“Lindau tumor”is the older term for cerebellarhemangioblastoma. Synonyms of the VHL-associatedendolymphatic sactumor have included “Heffner tumor,” aggressive papillarymiddle ear tumor(APMET),papillary adenomaor adenocarcinoma oftemporal bone, and low-grade adenocarcinoma of probable endolymphatic sac ...
