An auditory ossicles prosthesis has a head plate for abutment against an eardrum, and a shaft arranged on said head plate for bridging a tympanic cavity from the eardrum up to a stirrup or a stirrup footplate, and the head plate has a throughgoing passage through which the shaft can be pushed more or less so as to be cut at an opposite side of the head

Abstract Four auditory ossicles have been preserved from two of the individuals in the triple burial, Dolní Věstonice 14 and 15 (Figures 9.1 and 9.2). The former individual retains a left malleus and incus, both of which are well preserved but have their surfaces covered by thin calcareous encrustations. The malleus of Dolní Věstonice 15

Auditory ossicles from southwest Asian Mousterian sites
Journal of Human Evolution, 2008The present study describes and analyzes new Neandertal and early modern human auditory ossicles from the sites of Qafzeh and Amud in southwest Asia. Some methodological issues in the measurement of these bones are considered, and a set of standardized measurement protocols is proposed. Evidence of erosive pathological processes, most likely attributed

High Resolution Computed Tomography of Auditory Ossicles
Acta Radiologica, 1990Auditory ossicular sections were scanned at section thicknesses (mm)/section interspaces (mm) of 1.5/1.5 (61 patients), 1.0/1.0 (13 patients) or 1.5/1.0 (33 patients). At any type of section thickness/interspace, the malleal and incudal structures were observed with almost equal frequency. The region of the incudostapedial joint and each component part

Biomechanical properties of sterilized human auditory ossicles
Journal of Biomechanics, 1999Bone allograft material is treated with sterilization methods to prevent the transmission of diseases from the donor to the recipient. The effect of some of these treatments on the integrity of the bone is unknown. This study was performed to evaluate the effect of several sterilization methods on the mechanical behaviour of human middle ear bones. Due

Vascular Channels in the Auditory Ossicles in Man
Annals of Otology, Rhinology & Laryngology, 1974A second, extended study was made on the pattern of internal vascular anatomy of the stapes, incus, and malleus, employing serially sectioned specimens and reconstructions prepared from the sections. The descriptions and figures account, in detail, for the structural features in a specimen of a newborn infant and a 19-year-old male.

The auditory ossicles are composed of three small bones in the upper tympanic cavity. Ossicles are bound to each other by joints, thus creating an ossicular chain. They connect the tympanic membrane with the oval window to conduct the sound from the air to the fluid of the cochlea.

BONE CONDUCTION THROUGH THE AUDITORY OSSICLE CHAIN
Archives of Otolaryngology - Head and Neck Surgery, 1950IN THE performance of a bone conduction test the bone conduction tip is placed over the mastoid bone. This position of the bone conductor tip gives a theoretic constant. If all mastoid bones conducted sound waves equally well the bone conduction test would give a true estimation of the condition of the cochlea being examined, but the air cell ...

CHANGES IN THE AUDITORY OSSICLES IN OTOSCLEROSIS
Archives of Otolaryngology - Head and Neck Surgery, 1954IT WAS pointed out by Holmgren 1 in 1938 that in certain cases of otosclerosis the mobility of the malleus was either reduced or totally absent. Two parallel hairs inserted in a Siegle-Bruning speculum enabled him to judge the extent to which the handle of the malleus moves under compression and decompression.

Histochemical Study on Auditory Ossicle Matrices
British Journal of Audiology, 1969In a previous paper (24) a histochemical analysis of the constituent substrates of the stapedial footplate matrix and the mechanism by which this matrix can be degraded, enabled us to demonstrate that: (a) 24 hours treatment in citrate and acetate buffers, as well as trypsin and collagenase digestions determined only a weak reduction of the ...
