Embryonic in situ development is strictly regulated within the specific microenvironment of developing tissues. However, for regenerative medicine purposes (supplementation of damaged tissues/organs), transplantation to ectopic sites has been considered. To investigate developmental potential of fetal epiglottic epithelia at an ectopic site, fetal epiglottis was transplanted under the kidney ca...
The CobraPLATM is an alternative device for airway management. We report a case of airway obstruction caused by incarceration of the epiglottis in the epiglottic bars of the CobraPLATM during general anesthesia. Although the CobraPLATM was placed without difficulty on the first attempt, signs of airway obstruction were noted 2 h after insertion of the CobraPLATM. Using fiberoptic bronchoscopy, ...
OBJECTIVES Optical coherence tomography, an imaging modality using near-infrared light, produces cross-sectional tissue images with a lateral pixel resolution of 10 microm. However, normative data is first needed on epithelial thickness for lesion characterisation, and, to date, little exists. The purpose of our study is to measure normal laryngeal epithelial thickness by in vivo optical cohere...
causing an inability of the epiglottis to retroflex adequately during deglutition. The epiglottis then acted as an impediment to swallowing, instead of moving out of the way of the food bolus. Cervical osteophytes were one cause of pharyngeal crowding. However, pharyngeal crowding was also seen after anterior cervical spine surgery due to an increase in pharyngeal wall thickness. We therefore i...
BACKGROUND The upper airway tends to be obstructed during anesthesia in spontaneously breathing patients. The purpose of the current study was to determine the effect of increasing depth of propofol anesthesia on airway size and configuration in children. METHODS Magnetic resonance images of the upper airway were obtained in 15 children, aged 2-6 yr. Cross-sectional area, anteroposterior dime...
