The Basics of Velopharyngeal Function: A Brief Review for the ...
2012年10月1日 · In this article, I will provide a basic overview of the normal anatomy and physiology of velopharyngeal function. I will address topics such as the gross anatomy of the velopharyngeal mechanism, identification of the anatomy and function of the velopharyngeal musculature, and patterns of velopharyngeal closure that occur.
Fundamentals of Velopharyngeal Insufficiency - Springer
4 天之前 · The velopharyngeal insufficiency (VPI) is the inability of the velopharyngeal sphincter to seal the communication between the nasal cavities and the inferiorly located rest of the vocal tract during speech. The anatomical components of the velopharyngeal sphincter are the soft palate (velum), and the lateral and posterior pharyngeal walls.
Velopharyngeal Function and Disfunction - Cincinnati Children's ...
To produce most speech sounds, the air and sound need to be directed into the mouth and blocked from entering the nasal cavity. This is done through closure of the velopharyngeal valve. The velopharyngeal valve consists of the following structures: Velum (soft palate) Lateral pharyngeal walls − side walls of the throat.
Velopharyngeal Dysfunction - Children's Hospital of Philadelphia
What is velopharyngeal dysfunction? Velopharyngeal dysfunction (VPD) is a term used to describe disorders characterized by the abnormal function of the velopharyngeal valve, including velopharyngeal insufficiency (VPI). The velopharyngeal valve includes the soft palate as well as the pharynx and the side and back walls of the throat.
Velopharyngeal Insufficiency - StatPearls - NCBI Bookshelf
2023年1月12日 · Velopharyngeal insufficiency (VPI) is a disorder of the velopharyngeal (VP) sphincter or valve, which separates the nasal and oral cavities during speech, swallowing, vomiting, blowing, and sucking. The overall result is decreased speech intelligibility and significant functional and social impairment. It must be promptly diagnosed and treated ...
Diagnosis and Management of Velopharyngeal Dysfunction
Velopharyngeal dysfunction (VPD) describes any condition whereby the velopharyngeal valve does not properly close during the production of oral sounds, with multiple causes, including velopharyngeal mislearning (nasopharyngeal sound substitution for an oral sound), velopharyngeal incompetence (neurolophysiologic dysfunction causing poor ...
Management of velopharyngeal dysfunction: what is the role of …
This velopharyngeal (VP) closure is especially important when producing pressure sensitive sounds. During normal VP function, the posterior third of the soft palate moves posterior-superiorly, while the pharyngeal wall moves anteriorly and medially to form a sphincter to close the oral and nasal cavities.
Velopharyngeal Anatomy and Physiology | Perspectives of the …
2018年1月1日 · The purpose of this article is to provide a review of normal anatomy and physiology of the velopharynx. A brief application to velopharyngeal dysfunction and anatomical differences common to those with cleft palate will be provided. Judith Trost-Cardamone, The ASHA Leader, David L. Jones, SIG Perspectives, Kazlin Mason et al., SIG Perspectives,
Velopharyngeal Insufficiency: Etiopathology and Treatment
2017年9月20日 · SDB is due to obstruction of the velopharyngeal sphincter preventing the passage of the air column; even partial obstruction can lead to SDB. Research has shown that patients with cleft lip and palate have preexisting anatomical changes that favor the presence of SDBs such as apnea or hypopnea and in some patients surgeries attempting to ...
Anatomy of Velopharyngeal Portal - Springer
The purpose of this chapter is to describe the structure and function of the underlying musculature so that forces responsible for velopharyngeal movement can be more completely understood. However, it is not our intent to advance a theory of velopharyngeal physiology in this forum, but merely to summarize current thinking and controversies.
