introduction: in order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. one of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...
L’objectif principal était d’évaluer les résultats auditifs de la chirurgie l’otite moyenne chronique cholestéatomateuse (OMCC) l’adulte lors l’exérèse du malleus en comparaison à un groupe sans exérèse malleus. secondaire le rôle auditif stapes entre deux groupes. Notre étude cohorte observationnelle monocentrique incluait patients adultes opérés d’OMCC acquise avec ossiculoplastie 2015 et 201...
The objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. Twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. After dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. Finally, all data were evaluated and analysed using the Sigma Statt software. T...
Traumatic fracture of the malleus handle without tympanic membrane perforation is a rare incidence. Diagnosis of conductive hearing loss can only be confirmed with manipulation of the ossicles under sedation as computerized tomography is not informative. We present a 39-year-old lady with Q-tip injury when she get sudden phone call.
OBJECTIVE To report an original method of ossicular reconstruction with intact stapes and absent malleus. Ossiculoplasty is performed with a total ossicular replacement prosthesis positioned from the stapes footplate to the under-surface of the tympanic membrane, using a Silastic banding technique to stabilize the prosthesis. STUDY DESIGN A prospective study of ossicular reconstruction using ...
Middle ear dynamics in response to seismic stimuli in the Cape golden mole (Chrysochloris asiatica).
The hypertrophied malleus in the middle ear of some golden moles has been assumed to be an adaptation for sensing substrate vibrations by inertial bone conduction, but this has never been conclusively demonstrated. The Cape golden mole (Chrysochloris asiatica) exhibits this anatomical specialization, and the dynamic properties of its middle ear response to vibrations were the subjects of this s...
