Anatomy of the Velopharyngeal Valve

Abstract

Introduction: Understanding the normal anatomy and physiology of the velopharyngeal mechanism is the first step in providing appropriate diagnosis and treatment for children born with cleft lip and palate. The function of the velopharyngeal mechanism is to create a tight seal between the velum and pharyngeal walls to separate the oral and nasal cavities for various purposes, including speech. Objective of the review: To study the anatomy of velopharyngeal valve and its dysfunction Summary: The velopharyngeal valve is very important for normal speech production. This valve is made up of the following structures: Velum (also called soft palate) Lateral pharyngeal walls – the side walls of the throat Posterior pharyngeal wall – the back wall of the throat Conclusion: Understanding the anatomy of velopharyngeal valve is important to know various types of dysfunction
