      Optical coherence tomography and confocal laser scanning microscopy as non-invasive tools in the diagnosis of sinonasal inverted papilloma: a pilot study
      Optical coherence tomography (OCT) and confocal laser scanning microscopy (CLSM) are light-based imaging techniques that allow for a visualization of microscopic tissue properties in vivo. Our study was to examine whether they allow for differentiation of inverted papilloma (IP) from nasal polyps (NP). Five cases of IP and NP, respectively, were investigated intraoperatively with OCT and CLSM. Biopsies were taken of the investigated area and were analyzed ex vivo with ...

      Comparative study of presurgical skin infiltration depth measurements of melanocytic lesions with OCT and high frequency ultrasound
      A reliable, fast, and non-invasive determination of melanoma thickness in vivo is highly desirable for clinical dermatology as it may facilitate the identification of surgical melanoma margins, determine if a sentinel node biopsy should be performed or not, and reduce the number of surgical interventions for patients. In this work, optical coherence tomography (OCT) and high frequency ultrasound (HFUS) are evaluated for quantitative in vivo preoperative assessment of the skin ...

      Optical coherence tomography and confocal endomicroscopy for rhinologic pathologies: a pilot study
      Optical coherence tomography (OCT) and confocal endomicroscopy (CEM) have a well-established potential for early diagnosis of pre-malignant and early malignant lesions of the upper aerodigestive tract mucosa. Additional applications in ENT-diagnostics might facilitate a more widespread use by making the investment into the devices more economic. Both imaging techniques might also provide valuable information in nasal pathologies. OCT images were generated with a surgical microscope (Mller-Wedel Hi-R 1000) with an ...

      Corneal Responses to Eye Rubbing with Spectral Domain Optical Coherence Tomography
      Purpose: Surprisingly, a significant reduction (18.4%) in epithelial thickness was found after 15 seconds of eye rubbing measured using Holden-Payor optical pachometer reported in the literature. Hence, we aimed at studying the effects of compressive and shearing pressure associated with eye rubbing on total corneal, epithelial and Bowman’s membrane thickness using spectral domain OCT (SD-OCT). Methods: SD-OCT (Spectralis; Heidelberg Engineering) was used to acquire cross-sectional images of the ...

      An optical coherence tomography study for imaging the round window niche and the promontorium tympani
      Tympanosclerosis may involve the tympanic membrane, the ossicles, as well as the oval and round window niche, respectively. The surgical treatment of the obliterated oval window niche is most challenging. Beside stapesplasty, vibroplasty with coupling the floating mass transducer (FMT) onto the round window niche and into a new, so-called third window is indicated. In the latter situation, drilling a hole into the promontorium is necessary to couple the FMT ...

      OCT in the field of laryngology: further perspectives
      Early detection of cancerous lesions of the larynx may be the best method of improving patient quality of life and survival rates. New in-vivo technologies may be of great clinical relevance in improving the accuracy of sampling during microlaryngeal surgery. Optical coherence tomography (OCT) is an optical imaging technique that clearly identifies basement membrane violation caused by laryngeal cancer. With a microscope-based spectral domain OCT (SD-OCT) we reached in vivo ...

      Detection of tympanic membrane movement using film patch with integrated strain gauge, assessed by optical coherence tomography: experimental study
      Objective: We report an ex vivo and in vivo experimental study of a device designed to measure tympanic membrane movement under normal and pathological conditions, assessed using optical coherence tomography. Materials and methods: We designed two types of flexible, round film patch with integrated strain gauge, to be attached to the tympanic membrane in order to measure tympanic membrane movement. Tympanic membrane attachment was assessed using optical coherence tomography. The ...

      Optical coherence tomography allows for the reliable identification of laryngeal epithelial dysplasia and for precise biopsy: A clinicopathological study of 61 patients undergoing microlaryngoscopy
      Objectives/Hypothesis: A newly developed microscope-based spectral-domain optical coherence tomography (SD-OCT) device and an endoscope-based time-domain OCT (TD-OCT) were used to assess the inter-rater reliability, sensitivity, specificity, and accuracy of benign and dysplastic laryngeal epithelial lesions. Study Design: Prospective study. Methods: OCT during microlaryngoscopy was done on 35 patients with an endoscope-based TD-OCT, and on 26 patients by an SD-OCT system integrated into an operating microscope. Biopsies were taken from ...

      Explore Circulation Cardiology
      Both chronic and acute aortic conditions are challenges for primary care physicians and cardiac specialists. Longitudinal progression of chronic aortic diseases and appropriate timing of open or endovascular surgery are usually derived from serial noninvasive imaging studies. Rapid imaging is necessary as not to delay the diagnosis of a potentially life-threatening diagnosis. Given the frequency of missed cases of dissection, atypical presentation, and time-dependent morbidity and mortality, imaging is paramount ...
