Anatomy of the Velopharyngeal Valve

Anatomy of the Mitral Valve

In 1966 Barlow and Bosman(1) described a constellation of clinical fi ndings consisting of non-ejection systolic clicks and a late systolic murmur, T-wave abnormalities, and systolic aneurysmal billowing of the posterior mitral leafl et into the left atrium. Since then, in areas without rheumatic heart disease, mitral valve prolapse (MVP) has been portrayed as the most common form of valvular h...

Anatomy of the mitral valve.

According to Walmsley, 1 it was Andreas Vesalius who suggested the picturesque term “mitral” to describe the left atrioventricular valve owing to its resemblance to a plan view of the bishop’s mitre. Guarding the inlet to the left ventricle, the mitral valve prevents backflow to the left atrium during ventricular systole. In its open state, the valvar leaflets are like a funnel extending from t...

The Combination of Anatomy and Genioglossus Activity in Predicting the Outcomes of Velopharyngeal Surgery.

Objective This study aims to evaluate the combination of genioglossus (GG) activity and anatomical characteristics in predicting outcomes of velopharyngeal surgery in patients with obstructive sleep apnea (OSA). Study Design Case series with planned data collection. Setting Sleep medical center. Subjects and Methods Forty patients with OSA underwent overnight polysomnography with synchronous ge...

The effect of nasal speaking valve on the speech under experimental velopharyngeal incompetence condition.

Velopharyngeal incompetence (VPI) is a contributing factor to speech disorders, frequently accompanying disorders, such as cleft palate, congenital paralysis of the soft palate, and cerebrovascular disease. For the treatment of these types of dysarthria, a Nasal Speaking Valve (NSV), which regulates nasal emission utilizing one-way valve, has been reported to be effective. As the unpleasantness...
