The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area. It is also a key anatomic landmark for localizing disease processes in the surrounding spaces of ...
Nasopharyngeal carcinoma, also known as nasopharyngeal cancer, is classified as a malignant neoplasm, or cancer, arising from the mucosal epithelium of the nasopharynx, most often within the lateral nasopharyngeal recess or fossa of Rosenmüller (a recess behind the entrance of the eustachian tube opening).
Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). Clinical significance [ edit ]
A parapharyngeal abscess is a deep neck space abscess of the parapharyngeal space (or pharyngomaxillary space), which is lateral to the superior pharyngeal constrictor muscle and medial to the masseter muscle. [1] This space is divided by the styloid process into anterior and posterior compartments.
The torus tubarius (or torus of the auditory tube) is an elevation of the mucous membrane of the nasal part of the pharynx formed by the underlying base of the cartilaginous portion of the Eustachian tube (auditory tube). The torus tubarius is situated behind the pharyngeal orifice of the auditory tube. [1]
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
It is innervated by vagus nerve (cranial nerve X) via the pharyngeal plexus. It raises the pharynx and larynx during deglutition (swallowing) and laterally draws the pharyngeal walls up. It opens the pharyngeal orifice of the Eustachian tube during swallowing to allow for the equalization of pressure between it and the pharynx.
The function of the muscle is to obstruct the pharyngeal port at the moment that the pharyngeal lateral walls move towards each other. [ 2 ] [ 19 ] It is important that the width and the level of insertion of the flap are properly constructed, because if the flap is too wide, the patient can have problems with breathing through the nose, which ...
