OBJECTIVE To compare surgical outcomes between pharyngeal flap, sphincter pharyngoplasty, and combined Furlow palatoplasty and sphincter pharyngoplasty in the management of pediatric velopharyngeal insufficiency. STUDY DESIGN Case series with chart review. SETTING Tertiary care pediatric hospital. SUBJECTS AND METHODS After exclusion of children with velocardiofacial syndrome, 96 patients...

none) or who have been so subsidised bv the manufacturers. What would happen if everv university hospital applied the same restrictions? More worrying to me is the fact that where local National Health Service management labours under the delusion that drugs account for a considerable proportion of the overall costs of anaesthesia and intensive care a new breed of second class university depart...

Surgical management of velopharyngeal insufficiency by attachment of posterior pharyngeal flap or construction of sphincter pharyngoplasty is reviewed. Posterior pharyngeal flap surgery is well established, with a long history dating back to the 19th century. Flaps have been based superiorly, inferiorly, or laterally. There have been reports of airway obstruction and obstructive sleep apnea ass...

The aim of this study was to evaluate changes in the pharyngeal airway in growing children and adolescents and to compare these with a group of children who received activator-headgear Class II treatment. The sample consisted of 64 children (32 males and 32 females), 32 had a combined activator-headgear appliance for at least 9 months (study group) followed by fixed appliance therapy in most pa...

The acquisition and maintenance of shape is critical for the normal function of most cells. Here we investigate the morphology of the pharyngeal glands of Caenorhabditis elegans. These unicellular glands have long cellular processes that extend discrete lengths through the pharyngeal musculature and terminate at ducts connected to the pharyngeal lumen. From a genetic screen we identified severa...

INTRODUCTION  Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction. OBJECTIVE  To verify the correlation between nasopha...

The pharynx of Caenorhabditis elegans is a nearly self-contained neuromuscular organ responsible for feeding. To identify genes involved in the development or function of the excitable cells of the pharynx, I screened for worms with visible defects in pharyngeal feeding behavior. Fifty-two mutations identified 35 genes, at least 22 previously unknown. The genes broke down into three broad class...

The 22q11 deletion (22q11DS; velo-cardio-facial syndrome/DiGeorge syndrome) is characterized by defects in the derivatives of the pharyngeal apparatus. Mouse genetic studies have identified Tbx1, a member of the T-box family of transcription factors, as being responsible for the physical malformations of the syndrome. Mice heterozygous for a null mutation in Tbx1 have mild anomalies, whereas ho...
