Acoustics of the human middle-ear air space.

Middle ear ventilation status postoperatively after translabyrinthine resection of vestibular schwannoma with mastoid obliteration and Eustachian tube occlusion: is the Eustachian tube enough to ventilate the middle ear without the mastoid air cell system?

BACKGROUND Gas pressure balance is essential for maintaining normal middle ear function. The mucosal surfaces of the middle ear, the mastoid air cell system (MACS), and the Eustachian tube (ET) play a critical role in this process; however, the extent that each of these factors contributes to overall middle ear ventilation is unknown. The objective of this study was to determine if the ET alone...

CASE REPORT Pneumolabyrinth After Otic Capsule-Disrupting Temporal Bone Fracture without Direct Connection with the Middle Ear Space

have been several reports on pneumolabyrinth after stapes surgery, it has been rarely observed after temporal bone fracture. Air within the inner ear can be found even in the case having otic capsule-disrupting temporal bone fracture without definite connection with the middle ear space, which suggests the possible connection between the inner ear and the air-filled mastoid or middle ear caviti...

A Biological Gear in the Human Middle Ear

A three-dimensional (3D) finite element (FE) model was developed to simulate the motion modes of the human middle ear structures. The model was based entirely on 3D reconstruction obtained from micro Computed Tomography (microCT) imaging. We solve the acoustics-structure interaction problem using COMSOL Multiphysics. Our results show that at low frequencies, the classical hinging motion is domi...
