Cartilage implants: material, (usually from the patient's rib), is implanted to create an anterior projection on the pharyngeal wall. Most of the time, the success rate is low because the surgeons could not get a large enough sample from the ribs to stay in place in the pharyngeal wall. Later, several surgeons only performed this surgery on ...
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.
In 1876, Schenborn also attempted to reduce the amount of air entering the nasal cavity by developing the first true inferior based pharyngeal flap surgery, where a flap of tissue was sutured into the velum and attached to the lower end of the posterior pharyngeal wall. Modifying his technique, Schoenborn published a superior based pharyngeal ...
A common method to treat Velopharyngeal insufficiency is pharyngeal flap surgery, where tissue from the back of the mouth is used to close part of the gap. Other ways of treating velopharyngeal insufficiency is by placing a posterior nasopharyngeal wall implant (commonly cartilage or collagen) or type of soft palate lengthening procedure (i.e ...
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.
The danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V.
The pharyngeal raphe is a raphe that serves as the posterior attachment for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle). [1] [2] Two sides of the pharyngeal wall are joined posteriorly in the midline by ...
A posterior space abscess causes swelling in the posterior pharyngeal wall, and lockjaw is minimal. Other structures within the carotid sheath may be involved, causing rigors, high fever, bacteremia, neurologic deficit, or a massive haemorrhage caused by carotid artery rupture.
