He also stressed that stapedial
reflex testing <em>should not be presented as a diagnostic tool for autism</em>.
In this photograph down the external auditory canal with the tympanic membrane elevated, the pulsatile stapedial
artery can be seen running over the stapes footplate, between the anterior and posterior crura.
Mixed hearing loss gives the impression of stapedial
The thickness of the stapedial
crura from the outer to the inner surface is between 103 [micro]m and 134 [micro]m, which means that it is much shorter than the maximal diffusion distance in bone.
The theory of vascular injury, primarily to the stapedial
artery, is one that has held weight throughout the years.
reflex was absent on both sides, while the multiple-frequency tympanogram indicated a resonance frequency of 1000 Hz on the left and of 1100 Hz resonance on the right side.
Among their topics are the anatomy and physiology of the outer and middle ear, physical principles of aural acoustic immittance, acoustic stapedial
reflex, middle ear measurement in infants and children, and middle ear disorders and case examples.
Conductive deafness due to stapedial
abnormalities, associated with external ear malformations and congenital facial palsy (Sellars syndrome), is inherited as an AD disorder in a Cape Town family of Indian stock.
--Auditory alterations: deafness, stapedial
ankylosis, adysplasia of the pinna.
Jugal absent or vestigial; alisphenoid Oligoryzomys strut absent; stapedial
foramen present (pattern 2; Voss, 1988; except in Oligoryzomys rupestris); mesoloph and mesolophid frequently present (Fig.
The most common location of this disorder is the oval window, and it can lead to stapedial
ankylosis and subsequent conductive hearing loss.
Further, several studies attribute this variation to mechanical resonance and sound transfer function of the ear canal, the action of stapedial
reflexes, and genetics.
