Facial paraganglioma is an extremely rare tumor that originates from abnormal paraganglionic tissue situated in the intrapetrous facial canal. A review of the English-language literature shows that only 8 cases of facial nerve paraganglioma have been published. In each case the facial glomus presented itself sporadically, completely independent of any other form of paraganglioma. This study reports an intrapetrous facial glomus that occurred in a case of multiple paragangliomas with a hereditary pattern. To our knowledge, this is the first report of such a combination.

Article Synopsis
- A case study was done on a big tumor called giant glomus jugulare paraganglioma, which can cause hearing loss and ringing in the ears.
- The tumor was successfully removed without hurting the patient's facial nerve, and there were no signs of the tumor coming back after 2 years.
- This kind of tumor can be hard to recognize early on because it often shows different symptoms, making it rare to diagnose correctly at first.

Background & Objective: Glomus tympanicum and jugulare tumors are highly vascular and are therefore commonly embolized before surgical resection to prevent intra-operative bleeding. We report a case of facial nerve paralysis after pre-operative embolization for a glomus tympanicum tumor with ethylene vinyl alcohol (EVOH also known as Onyx) embolic agent. We discuss the choice of embolic agent in relation to the risk of this complication and potential management strategies.

Glomus tympanicum is a type of glomus tumor that affects the middle ear, located at the auricular branch of the vagus nerve. Glomus tumors, in general, are rare, slow-growing tumors and may not require surgery in some patients. It can be challenging to manage due to its hypervascularity, location, and advanced stage of diagnosis.
