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 ...
On its lateral wall is the pharyngeal opening of the auditory tube, somewhat triangular in shape and bounded behind by a firm prominence, the torus tubarius or cushion, caused by the medial end of the cartilage of the tube that elevates the mucous membrane. Two folds arise from the cartilaginous opening:
The maxillary prominence forms the lateral wall and floor of the orbit, and in it are ossified the zygomatic bone and the greater part of the maxilla; it meets with the medial nasal prominence, from which, however, it is separated for a time by a groove, the naso-optic furrow, that extends from the furrow encircling the eyeball to the nasal pit.
The torus tubarius is situated behind the pharyngeal orifice of the auditory tube. [ 1 ] The torus tubarius is very close to the tubal tonsil , [ 1 ] which is sometimes also referred to as the tonsil of (the) torus tubarius . [ 2 ]
Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). Clinical significance [ edit ]
The canthus (pl.: canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet. [1] More specifically, the inner and outer canthi are, respectively, the medial and lateral ends/angles of the palpebral fissure. The bicanthal plane is the transversal plane linking both canthi and defines the upper boundary of ...
In this flap, lateral ports exist on both sides of the pharyngeal flap to assist in drainage, nasal breathing, and nasal resonance. Using the pressure-flow studies of Warren and colleagues as a basis for lateral port size, Hogan placed a 4 mm diameter catheter through the lateral ports on either side of the flap to tailor the port size to the ...
The signs and symptoms of an infratemporal space infection are swelling of the face in the region of the sigmoid notch, swelling of the mouth in the region of the maxillary tuberosity and marked trismus (difficulty opening the mouth), since some of the muscles of mastication are restricted by the swelling.
