The ears of stridulating crickets are exposed to loud self-generated sounds that might desensitise the auditory system and reduce its responsiveness to environmental sounds. We examined whether crickets prevent self-induced auditory desensitisation, and measured the responsiveness of the peripheral auditory system of the cricket (acoustic spiracle, tympanic membrane and tympanic nerve) during p...

OBJECTIVE The goal of this study was to analyze whether tympanic plexus neurectomy is a successful surgical option in patients with intractable otalgia. STUDY DESIGN A retrospective single institution study from the experience of two surgeons was conducted. METHODS Records of adult patients with intractable unilateral otalgia of likely glossopharyngeal origin were reviewed, with institution...

Rats are potentially very useful for auditory research because the middle ear structures are easily approachable and because rats are relatively inexpensive. The goal of the present study was to better characterize the mechanics of the rat middle ear by measuring frequency responses at multiple points on the tympanic membrane and manubrium. A laser Doppler vibrometer was used to measure the vib...

Hemangiomas of the external auditory canal, involving the posterior bony canal and the adjacent tympanic membrane, although rare, are considered a specific disease entity of the human external auditory canal. Hemangiomas of the tympanic membrane and/or external auditory canal are rare entities; there are 16 previous case reports in the literature. It is a benign vascular tumor. It generally occ...

The mechanical behavior of the tympanic membrane displays both non-linearity and viscoelasticity. Previous finite-element models of the tympanic membrane, however, have been either non-linear or viscoelastic but not both. In this study, these two features are combined in a non-linear viscoelastic model. The constitutive equation of this model is a convolution integral composed of a non-linear e...

BACKGROUND AND PURPOSE The prevalence of tympanic plate fractures, which are associated with an increased risk of external auditory canal stenosis following temporal bone trauma, is unknown. A review of posttraumatic high-resolution CT temporal bone examinations was performed to determine the prevalence of tympanic plate fractures and to identify any associated temporal bone injuries. MATERIA...
