Diagnostic contributions of videolaryngostroboscopy in the pediatric population.
Videolaryngostroboscopy (VLS) is a standard technique used for evaluating adult patients with dysphonia. However, while pediatric dysphonia affects 5% of children, children with dysphonia are traditionally examined with a flexible nasal endoscope. The purpose of this study was to determine whether VLS provides additional diagnostic yield in children. ⋯ Patients with a history of prolonged dysphonia for whom treatment has failed should be referred for evaluation by VLS. Videolaryngostroboscopy elucidates subtle features of different disease processes; clarifies the differences between benign mucosal disorders that might require surgical intervention; and helps identify inflammatory processes that contribute to dysphonia. To our knowledge, these findings have not previously been reported in the pediatric population. Although most pediatric dysphonia can be attributed to benign nodules, our results show that inflammatory conditions and benign lesions other than nodules contribute to dysphonia and are often overlooked and undertreated.

Effect of a novel anatomically shaped endotracheal tube on intubation-related injury.
To develop an anatomically shaped endotracheal tube (ETT) and to compare the degree of induced laryngeal injury of this ETT with that of a standard ETT using an animal model. ⋯ The modified ETT objectively caused less laryngotracheal damage compared with the standard ETT and may be of potential clinical benefit.
