Disease and Treatment-Related Sequelae in Patients with Complex Jugulotympanic Paraganglioma

Background: Jugulotympanic paraganglioma (JTP) are benign, high-vascularized lesions that frequently invade the jugular foramen, temporal bone, the upper neck, and the posterior fossa cavity, resulting in a wide variety of clinical symptoms. Methods: In this retrospective study, we assess the clinical symptoms and discuss the individual multidisciplinary treatment and outcome of 22 patients with JTP. Results: In 12 patients, a hearing deficit was the presenting symptom, whereas pulsatile tinnitus and otalgia were present in six and four patients respectively. Facial nerve involvement was seen in six patients (three HB Grade 1–2 and three HB Grade 4–6). Four patients presented with lower cranial nerve impairment. Rare symptoms were ataxia caused by brainstem compression and papilledema due to cerebral sinus obstruction. A new or worsening of the preoperative facial nerve or lower cranial nerve function occurred in two and four patients respectively. Conclusion: The treatment strategy and the surgical approach for JTP should be tailored to the tumor extension and the patient’s clinical symptoms.
