Feb 3, 2022 · The fossa of Rosenmüller, also known as the posterolateral pharyngeal recess, is the most common site of origin for nasopharyngeal carcinoma 5. It is located superior and posterior to the torus tubarius (the posterior projection of the cartilaginous portion of the Eustachian tube) and is formed by mucosal reflection over the longus colli muscle 2.

Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). At the base of this recess is the retropharyngeal lymph node (the node of Rouvière). This is clinically significant in that it may be involved in certain head and neck cancers, notably nasopharyngeal cancer.

Fossa of Rosenmüller is a herniation of the nasopharyngeal mucosa through this deficiency between skull base and superior most fibers of the superior constrictor muscle. Through this gap bridged only by the pharyngobasilar fascia, the eustachian tube enters the nasopharynx with its two muscles, one on each side.

Jul 5, 2021 · The fossa of Rosenmüller, also known as the posterolateral pharyngeal recess, is located superior and posterior to the torus tubarius (posterior projection of the cartilaginous portion of the Eustachian tube), formed by the mucosal reflection over the longus colli muscle.

Key words: Nasopharynx, Fossa of Rosenmüller, Nasopharyngeal carcinoma, Cone beam computed tomography. The location of Rosenmüller fossa (RF), also known as the lateral pharyngeal recess, is in the superior-most side of the lateral surface of the nasopharynx (1). In 1808, the RF anatomy was first mentioned by Johann Christian Rosenmüller (2).

The fossa of Rosenmüller, also known as the posterolateral recess, is the most common site of origin for nasopharyngeal carcinoma. It is located superior and posterior to the torus tubarius (the posterior projection of the cartilaginous portion of the eustachian tube), and is formed by mucosal reflection over the longus colli muscle.

Behind the ostium of the auditory tube is a deep recess, the pharyngeal recess (fossa of Rosenmüller). IMAIOS is a company which aims to assist and train human and animal practitioners. Serving healthcare professionals through interactive anatomy atlases, medical imaging, collaborative database of clinical cases, online courses...

Mar 20, 2016 · The lateral wall of the nasopharynx includes the fossa of Rosenmüller, located lateral and posterior to the torus tubarius (the cartilaginous opening of Eustachian tube); the fossa is the most common site of primary nasopharyngeal carcinoma (NPC) (Figs. 3.1 and 3.2).

Two cases of mucous retention cysts originating from the fossa of Rosenmüller are described, together with their character-istic radiologic appearance, which allows differentiation from other types of lesions in this region. The differential diagnosis and treatment options are discussed.

Feb 18, 2019 · The objective of this study was to assess Rosenmüller fossa (RF) anatomy and neighboring structures using cone beam computed tomography (CBCT). A total of 1000 patients were analyzed using CBCT.
