Intraoperative endoscopic photos with and without false cord retraction via the Lindholm laryngeal distending forceps were obtained from the Seattle Children's Hospital airway endoscopy photo library. Analysis was performed using imaging software. Comparisons of visible vocal cord and glottic opening areas as well as anterior commissure angles with and without the Lindholm laryngeal distending forceps were performed with a paired and unpaired Student t test.Results: The use of the Lindholm laryngeal distending forceps increased the glottic opening by a mean of 359% (95% confidence interval [CI], 255%-463%) and increased visualized true vocal cord area by 337% (197%-477%). Angle at the anterior commissure increased from a mean of 24.9° to a mean of 71.5°, resulting in a net mean angle increase of 46.6° (95% CI, 40.2°-52.9°). All measured changes were statistically significant with P values <.01.Conclusions: When placed at the level of the false vocal folds, Lindholm laryngeal distending forceps will, at least in certain cases, greatly increase the visible area of the superior surface of the vocal folds, the anterior commissure, and, by increasing the glottic opening, the subglottic region. This improved visualization may enhance the surgeon's ability to diagnose and treat pathologies in these anatomic regions during direct laryngoscopy. pubtype: Academic Journal doctype: research Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
