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.
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 ...
Nasopharyngeal cyst refers to cystic swelling arising from midline and lateral wall of the nasopharynx. The commonest cyst arising from lateral wall is the nasopharyngeal branchial cyst, whereas the mucus retention cysts are the commonest to arise from the midline. [1] Sometimes nasopharyngeal cyst may directly refer to Tornwaldt cyst. [2]
A CT scan shows a solid mass of Tornwaldt's cyst and MRI shows a glass-shaped lesion with fluid on the upper part of the posterior nasopharyngeal wall. Additionally, a cystic mass in the upper part of the nasopharyngeal wall and mucopurulent discharge from upper part of the mass can be seen on nasal endoscopy. Among them MRI is the best for ...
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.
Retropharyngeal abscess (RPA) is an abscess located in the tissues in the back of the throat behind the posterior pharyngeal wall (the retropharyngeal space).Because RPAs typically occur in deep tissue, they are difficult to diagnose by physical examination alone.
[126] [127] [5] This is due to evidence suggesting that transmission rates of HPV from women to men are higher than from men to women, as women often have a higher immune response to infection. [5] [128] In 2008, there were 22,900 cases of oral cavity cancer, 12,250 cases of laryngeal cancer, and 12,410 cases of pharyngeal cancer in the United ...
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 ...
