Pierre Robin sequence [a] (/ p j ɛər r ɔː ˈ b æ̃ /; [3] abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities.The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway.
Multiview videofluoroscopy is a radiographic technique to view the length and movement of the velum (soft palate) and the posterior and lateral pharyngeal (throat) walls during speech. The advantage of this technique is that the entire posterior pharyngeal wall can be visualized. Disadvantages include the following: 1.
Additionally, aberrant pharyngeal vascular anatomy can serve as a contraindication to the pharyngeal flap surgical procedure. Internal carotid arteries within the pharyngeal walls can take an atypical medial course through the posterior aspect of the pharyngeal wall, particularly in patients with velocardiofacial syndrome.

Augmentation pharyngoplasty is a kind of plastic surgery for the pharynx (soft tissue at the back of the mouth) when the tissue at the back of the mouth is not able to close properly. It is typically used to correct speech problems in children with cleft palate .
Glossoptosis is a medical condition and abnormality which involves the downward displacement or retraction of the tongue. [1] It may cause non-fusion of the hard palate , causing cleft palate . It is one of the features of Pierre Robin sequence and Down syndrome .
Tornwaldt's disease is a rare benign disorder caused by persistent notochord remnants. [3] This disease almost remains asymptomatic. [citation needed] At about the 10th week of embryonic development, the pharyngeal pouch forms by adhesion of the pharyngeal ectoderm to the cranial end of the notochord.
A Zenker's diverticulum, also pharyngeal pouch, is a diverticulum of the mucosa of the human pharynx, just above the cricopharyngeal muscle (i.e. above the upper sphincter of the esophagus). It is a pseudo diverticulum or false diverticulum (only involving the mucosa and submucosa of the esophageal wall, not the adventitia), also known as a ...
