1. Feature Of The Week 11/15/09: A Comparison between Optical Coherence Tomography and Histology of Laryngeal Epithelial Thickness
  
  Explore Optical Coherence Tomography News Nov 15 2009 Otolaryngology
  
  Feature Of The Week 11/15/09: While applications of optical coherence tomography in ophthalmology and cardiology have very successfully transitioned from the research world to the commercial world many other fields have lagged behind. One such area is the field of Otolaryngology. While much of the technology developed in both the academic and commercial worlds is directly applicable to applications in otolaryngology there remain some unique features such as probe design and a need for additional clinical data to determine where OCT will be most beneficial. Numerous researchers around the world are working in this field. Researchers from the ...

2. Gradient-index lens rod based probe for office-based optical coherence tomography of the human larynx
  
  Explore SPIE Digital Library Feb 11 2009 Gastroenterology , Otolaryngology
  
  Optical coherence tomography (OCT) is an evolving noninvasive imaging modality that has been used to image the human larynx during surgical endoscopy. The design of a long gradient-index lens-based probe capable of capturing images of the human larynx by use of spectral domain OCT during a typical o ... [J. Biomed.

  Optical coherence tomography (OCT) is an evolving imaging modality that combines interferometry with low-coherence light to produce high-resolution tissue imaging. Cross-sectional in vivo images were obtained using an OCT device consisting of a Michelson interferometer, 1.3-µm broadband light source, and a handheld fiberoptic imaging probe. Image pixel resolution approached 10 µm. The mucosa of the oral cavity and oropharynx were examined in 41 patients during operative endoscopy. Optical coherence tomographic imaging was combined with endoscopic photography for gross and histologic image correlation. Optical coherence tomographic images of the oral cavity and oropharynx provided microanatomical information on the epithelium, basement ...

4. Optical Coherence Tomography–Enhanced Microlaryngoscopy: Preliminary Report of a Noncontact Optical Coherence Tomography System Integrated With a Surgical Microscope

  Objectives: Optical coherence tomography (OCT) is a new imaging modality that uses near-infrared light to produce cross-sectional images of tissue with a resolution approaching that of light microscopy. We have previously reported use of OCT imaging of the vocal folds (VFs) during direct laryngoscopy with a probe held in contact or near-contact with the VFs. This aim of this study was to develop and evaluate a novel OCT system integrated with a surgical microscope to allow hands-free OCT imaging of the VFs, which could be performed simultaneously with microscopic visualization. Methods: We performed a prospective evaluation of a new method ...

5. Optical Coherence Tomography of the Newborn Airway
  
  Explore annals.com Jun 21 2008 Otolaryngology , Pulmonology
  
  Objectives: Acquired subglottic stenosis in a newborn is often associated with prolonged endotracheal intubation. This condition is generally diagnosed during operative endoscopy after airway injury has occurred. Unfortunately, endoscopy is unable to characterize the submucosal changes observed in such airway injuries. Other modalities, such as magnetic resonance imaging, computed tomography, and ultrasound, do not possess the necessary level of resolution to differentiate scar, neocartilage, and edema. Optical coherence tomography (OCT) is an imaging modality that produces high-resolution, cross-sectional images of living tissue (8 to 20 μm). We examined the ability of this noninvasive technique to characterize the newborn airway in ...
