Acoustic Screening of the “Wet voice”: Proof of Concept in an <i>ex vivo</i> Canine Laryngeal Model Open
Background Current protocols for bedside swallow evaluation have high rates of false negative results. Though experts are not consistently able to screen for aspiration risk by assessing vocal quality, there is emerging evidence that vocal…

Computational Modeling of Nasal Drug Delivery Using Different Intranasal Corticosteroid Sprays for the Treatment of Eustachian Tube Dysfunction Open
Eustachian tube dysfunction (ETD) is a common otolaryngologic condition associated with decreased quality of life. The first-line treatment of ETD is intranasal corticosteroid sprays (INCS). Computational fluid dynamics (CFD) was used to s…

Predicting critical closing pressure in children with obstructive sleep apnea using fluid-structure interaction Open
We present a noninvasive method for estimating critical closing pressure (Pcrit) using fluid-structure interaction (FSI) simulations and magnetic resonance imaging (MRI) scans in patients with obstructive sleep apnea (OSA). We used patient…

Impact of Vertical Stiffness Gradient on the Maximum Divergence Angle Open
Introduction During vocal fold vibration, the medial surface of both folds forms a convergent shape during opening and a divergent shape during closing. A greater maximum divergence angle is associated with greater closing forces which wil…

Best practices for emergency surgical airway: A systematic review Open
Objective In the case of an emergency surgical airway, current guidelines state that surgical cricothyrotomy is preferable to tracheotomy. However, complications associated with emergency cricothyrotomy may be more frequent and severe. We …

Comparative Treatment Outcomes for Patients With Idiopathic Subglottic Stenosis Open
In this cohort study of 810 patients with iSGS, endoscopic dilation, the most popular surgical approach for iSGS, was associated with a higher recurrence rate compared with other procedures. Cricotracheal resection offered the most durable…

Predicting Intelligibility Deficit in Dysphonic Speech with Cepstral Peak Prominence Open
Objectives: The aim of this study was to examine the potential of cepstral peak prominence (CPP) for predicting the intelligibility deficit in dysphonic speech. Methods: Sentences from Hearing-in-Noise Test were recorded from 18 speakers w…
View article: The Effect of Background Noise on Intelligibility of Dysphonic Speech
The Effect of Background Noise on Intelligibility of Dysphonic Speech Open
Purpose The aim of this study is to determine the effect of background noise on the intelligibility of dysphonic speech and to examine the relationship between intelligibility in noise and an acoustic measure of dysphonia: cepstral peak pr…
View article: Effect of vocal fold asymmetries on glottal flow
Effect of vocal fold asymmetries on glottal flow Open
Objectives/Hypothesis Voice disorders, such as unilateral vocal fold paralysis or paresis, and vocal fold scarring feature structural asymmetries of the vocal folds. Studies on how structural asymmetries affect voice has mostly been limite…
