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).
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.
How are NPCS diagnosed?
Nasopharyngeal cancer (NPC) is most often diagnosed when a person goes to a doctor because of symptoms such as a lump in the neck or stuffy nose, but no signs of a cold. The doctor will take a history and do an exam. The patient may then be sent to see an ear, nose and throat (ENT) specialist.
Where does nasopharyngeal cancer spread?
Most people with nasopharyngeal carcinoma have regional metastases. That means cancer cells from the initial tumor have migrated to nearby areas, such as lymph nodes in the neck. Cancer cells that spread to other areas of the body (distant metastases) most commonly travel to the bones, lungs and liver.
Where is the fossa of Rosenmuller?
nasopharynx
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 does the trigeminal nerve supply?
The trigeminal nerve is the largest and most complex of the 12 cranial nerves (CNs). It supplies sensations to the face, mucous membranes, and other structures of the head. It is the motor nerve for the muscles of mastication and contains proprioceptive fibers.
What is early stage nasopharyngeal cancer?
Stage I is early-stage nasopharyngeal cancer that has not spread to lymph nodes or distant parts of the body. Stage II is nasopharyngeal cancer that may have spread to nearby tissues and lymph nodes but has not spread to distant parts of the body.

What is nasopharynx oropharynx?
The nasopharynx represents the most superior portion of the pharynx, bounded superiorly by the skull base and inferiorly by the soft palate. The nasopharynx connects the nasal cavity to the oropharynx and contains the Eustachian tube openings and adenoids.
What is the pathophysiology of targettrotter’s triad?
Trotter’s triad is a unique symptom complex associated with malignant tumours invading the lateral wall of nasopharynx. Pathognomonic features in sequential order include ipsilateral conductive hearing loss, trigeminal nerve neuralgia affecting the mandibular division and palatal asymmetry.
