What is the fossa of Rosenmüller?

The fossa of Rosenmüller is a bilateral projection of the nasopharynx just below the skull base. It is also called the lateral pharyngeal recess or simply the pharyngeal recess. The fossa is covered by nasopharyngeal mucosa and is the most common site of origin of nasopharyngeal carcinoma (NPC).

What is found in the pharyngeal recess?

At the base of this recess is the retropharyngeal lymph node (the Node of Rouvier). This is clinically significant in that it may be involved in certain head and neck cancers, notably nasopharyngeal cancer.

What is Trotter Triad?

Trotter’s syndrome is a clinical triad of unilateral deafness, neuralgia affecting branches of the trigeminal nerve, and defective mobility of the soft palate, which is caused by malignant tumors involving the lateral pharyngeal recess (Rosenmüller’s fossa).

What is Thornwaldt cyst?

A Tornwaldt cyst (Thornwaldt cyst) is a developmental benign cyst [1]. It presents in the midline within the nasopharynx. It represents a persistent communication between the roof of the nasopharynx and the notochord.

What drains into pharyngeal recess?

The Pharyngeal recess is a deep recess behind the ostium of the pharyngotympanic (Eustachian) tubethat connects the middle ear cavity (tympanum) with the nasopharynx. It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx.

Which branch of trigeminal nerve is involved in Trotters Triad?

Trotter’s syndrome is a cluster of symptoms associated with certain types of advanced nasopharyngeal carcinoma. The cause of pain is the mandibular nerve of the foramen ovale, through which the tumor enters the calvarium.

What neuralgia means?

Neuralgia is pain in a nerve pathway. Generally, neuralgia isn’t an illness in its own right, but a symptom of injury or particular disorders. In many cases, the cause of the pain is not known. The pain can generally be managed with medication, physical therapies or surgery.

What is levator Veli palatini?

The levator veli palatini (levator) muscle is considered to be the primary muscle responsible for velar elevation. As its name implies, it functions to elevate the velum to create closure between the oral and nasal cavities (Moon and Kuehn, 2004).
