      Evaluation of middle ear reconstruction by endoscopic Optical Coherence Tomography

      Introduction Endoscopic Optical Coherence Tomography (eOCT) allows high-resolution 3-dimensional imaging of the tympanic membrane and the adjacent areas of the middle ear. Doppler-OCT enables oscillation measurement. Thus, the postoperative outcome of tympanoplasty can be evaluated. Material and Methods 5 Patients were examined after tympanoplasty using eOCT. The system utilizes a near infrared laser with a central wavelength of 1300 nm and a working range of 8 mm. The thickness of the tympanic membrane and of the reconstruction were determined as well as the coupling of the prostheses. Furthermore, the oscillation of the reconstructed tympanic membrane and of the prostheses was ...

    2. Endoscopic Optical Coherence Tomography in Diagnostics of Otosclerosis

      Endoscopic Optical Coherence Tomography in Diagnostics of Otosclerosis

      Introduction: Endoscopic Optical Coherence Tomography (eOCT) enables both high-resolution contact-free 3D-imaging of the tympanic membrane and spatial and frequency-resolved oscillation measurement via Doppler-OCT. Thus it is possible to detect causes of conduction hearing loss. In case of otosclerosis, changes in oscillation amplitude at the umbo had been showed via Laser-Doppler-Vibrometry. Material and Methods: The eOCT system utilizes a swept source laser with a wave length around 1300nm. Field-of-view and working distance are 10 mm. Sound stimulus was a Chirp in the frequency range between 0.5 and 5 kHz at 95 dB. Morphological and functional measurements were done on 12 ...

    3. A System for Clinical Use of Endoscopic Optical Coherence Tomography

      A System for Clinical Use of Endoscopic Optical Coherence Tomography

      Introduction: Optical Coherence Tomography (OCT) allows non-invasive high-resolution imaging of tissues. With a penetration depth of a few millimeters it's possible to image the tympanic membrane and the close-by part of the tympanum, e.g. for diagnostics of otitis media and middle ear effusion. In the field of in vivo examination there are difficulties in access to the human tympanic membrane due to the narrow and curved external ear canal. We report a compact endoscopic OCT system for use in clinical research. Methods: We use a 3,5 mm endoscopic GRIN lens for video endoscopy and OCT. OCT is ...
