An Exploratory Analysis of Early Care Differences and Risk of Post-Maxillary Advancement VPI in Individuals With Cleft Palate.
Cleft Palate Craniofac J
January 2025
Seattle Children's Hospital, Craniofacial Center, Seattle, WA, USA.
Objective: To investigate whether differences in early cleft care increase risk of velopharyngeal insufficiency (VPI) after maxillary advancement.
Design: Retrospective cohort study.
Setting: Large pediatric tertiary care hospital.
Aerodynamic and Acoustic Power in Infant Cry.

Utah Center for Vocology, University of Utah, Salt Lake City, UT; National Center for Voice and Speech, Salt Lake City, UT. Electronic address:
Objectives: Acoustic and aerodynamic powers in infant cry are not scaled downward with body size or vocal tract size. The objective here was to show that high lung pressures and impedance matching are used to produce power levels comparable to those in adults.
Study Design And Methodology: A computational model was used to obtain power distributions along the infant airway.
"My Voice Sounds Different": A Case of Acute Idiopathic Velopharyngeal Insufficiency.

November 2024
Pediatrics, Unidade Local de Saúde do Alto Minho, Viana do Castelo, PRT.
This report details a case of acute idiopathic velopharyngeal insufficiency in a previously healthy eight-year-old girl, presenting with sudden voice alteration and nasal regurgitation following mild respiratory symptoms. Physical examination identified unilateral velar paralysis with open rhinolalia, without additional neurological deficits. Extensive diagnostic evaluation, including nasopharyngoscopy, cerebral and cervical imaging, and infectious serologies, yielded unremarkable findings.

Identification and quantification of speech variations in velar production across various phonological environments have always been an interesting topic in speech motor control studies. Dynamic magnetic resonance imaging has become a favorable tool for visualizing articulatory deformations and providing quantitative insights into speech activities over time. Based on this modality, it is proposed to employ a workflow of image analysis techniques to uncover potential deformation variations in the human tongue caused by changes in phonological environments by altering the placement of velar consonants in utterances.

Article Synopsis
- Crocodylians have a specialized gular valve that forms a water-tight seal in their mouths, allowing them to dive while keeping their mouths open.
- This study reveals that the gular valve consists of an integrated dorsal component (the dorsal gular fold) and a mobile ventral part (the tongue and hyolingual apparatus), connected by a newly identified structure called the velar chord.
- The findings suggest that the tension in the velar chord changes the shape of the dorsal gular fold, affecting various behaviors like swallowing and vocalization beyond just diving.
