Methodology for Intraoperative Laser Doppler Vibrometry Measurements of Ossicular Chain Reconstruction
OBJECTIVES Despite the increasing number of research concerning the applications of the Laser Doppler Vibrometry (LDV) in medicine, its usefulness is still under discussion. The aim of this study is to present a methodology developed in our Department for the LDV intraoperative assessment of ossicular chain reconstruction. METHODS Ten patients who underwent "second look" tympanoplasty were in...
متن کاملLaser 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 کاملBone cements as adjuvant techniques for ossicular chain reconstruction.
HYPOTHESIS The osseointegrative capacity of medical-grade bone cement can be used to improve fixation and prevent displacement of an ossicular prosthesis in a guinea pig model. BACKGROUND Successful ossiculoplasty requires a firm connection between the vibrating tympanic membrane and the inner ear. In patients requiring revision ossiculoplasty, half of failures are due to prosthesis displacem...
متن کاملSpatially encoded multibeam laser Doppler vibrometry using a single photodetector.
A laser Doppler vibrometer with single photodetector is introduced to measure the vibration on multiple points of target simultaneously. A 2 x 5 beam array with various frequency shifts is generated by three acousto-optic devices, illuminating different points on a vibrating object. The reflected beams interfere with a reference beam on a high-speed photodetector, and the signal is amplified an...
