BACKGROUND Bleeding within the supraglottic region can be a lethal complication after CO(2) laser microsurgery. Our aim was to propose endoluminal anatomical landmarks to locate the superior laryngeal vessels resulting in a safer microsurgery. METHODS Endoluminal dissections were made in 22 larynges without laryngeal disease. RESULTS The neurovascular structures were in the superior third o...

BACKGROUND Transoral robotic surgery (TORS) has facilitated organ-preserving surgery of the larynx. It has also presented a change in the surgical perspective. We performed cadaveric dissections using the robot to highlight the vascular and muscular anatomy of the supraglottic larynx. METHODS Cadaveric specimens underwent injection of their vasculature, and after injection a robotic surgical ...

The I-gel airway is a novel supraglottic airway that uses an anatomically designed mask made of a gel-like thermoplastic elastomer. We studied the positioning and mechanics of this new device in 65 non-embalmed cadavers with 73 endoscopies (eight had repeat insertion), 16 neck dissections, and six neck radiographs. A full view of the glottis (percentage of glottic opening score 100%) occurred i...

We have measured changes in supraglottic airway resistance (Rsg) produced by midazolam. Ten subjects were studied on two occasions, receiving in a random order either midazolam 0.1 mg kg-1 or placebo. Supraglottic pressures were measured using a balloon-tipped catheter and air flow with a pneumotachograph. Rsg were calculated at a flow rate of 0.3 litre s-1 during inspiration. No changes in Rsg...

Prune belly syndrome (PBS) is a rare congenital disease presenting characteristic triad of abdominal muscle deficiency, urinary tract abnormality, and cryptorchidism with associated anomalies various systems. We report the anesthetic management an infant PBS no obvious facial deformity in whom we encountered unanticipated difficult airway. Multiple attempts to secure airway different supraglott...
