Laser Doppler Vibrometry measurements of human cadaveric tympanic membrane vibration
OBJECTIVE To determine the feasibility of measuring tympanic membrane (TM) vibrations at multiple locations on the TM to differentiate normal eardrums from those with associated ossicular pathologies. DESIGN Cadaveric human temporal bone study. SETTING Basic science laboratory. METHODS A mastoidectomy and facial recess approach was performed on four cadaveric temporal bones to obtain acce...
متن کاملMiddle Ear Exploration Results in Suspected Otosclerosis Cases Referred to Amir-Almomenin and Golsar Hospitals, Rasht, 2001-2011: Are Ossicular and Footplate Area Anomalies Rare?
Introduction: Otosclerosis is a disease of bony labyrinth. Structural changes in the labyrinth often cause ossicular fixation, and thus conductive hearing loss. The purpose of this study was to evaluate middle ear exploration findings and frequency of ossicular and footplate area anomalies in patients with suspected otosclerosis referred to Amiralmomenin and Golsar Hospitals in Rasht, Iran. M...
متن کاملFirst results of a novel adjustable-length ossicular reconstruction prosthesis in temporal bones.
OBJECTIVES/HYPOTHESIS The performance of an ossicular replacement prosthesis (ORP) is influenced by its alignment and appropriate tension between the tympanic membrane and the stapes footplate. A novel ORP with a flexible element that potentially allows for length adjustment in situ is presented and tested for acoustic performance. STUDY DESIGN Laser Doppler vibrometry in fresh human cadaveri...
متن کاملThe natural vibration characteristics of human ossicles.
BACKGROUND Recently, a model of the ossicular chain for finite element analysis has been developed. However, the natural vibration characteristics of human ossicles have never been studied. Herein, we investigated the dynamic characteristics of the coupling of in-vivo ossicles using finite element analysis. METHODS The geometry of the ossicular chain was obtained by high-resolution computed t...
