Jugular Paragangliomas

Background: Jugular paragangliomas are rare, almost exclusively benign and slowly growing tumors. Arising from the cells of paraganglia in jugular bulb, they infiltrate the temporal bone and later grow intracranially. Because of insidious onset, their diagnosis is relatively late. Patients at presentation usually complain of pulsatile tinnitus and hearing loss, lasting for years. Also common are palsies of the cranial nerves in the area of tumor growth – i.e., facial, glossopharyngeal, vagal, accessory and hypoglossal nerves. Surgical resection is the standard treatment, though technically demanding because of difficult approach to the lateral cranial base and vital structures in the area. The team for treating such patients comprises an ENT specialist, interventional radiologist and a neurosurgeon. The purpose of this article is to review clinical experiences with the treatment of jugular paragangliomas at our Department of ENT and Maxillofacial Surgery of the University Medical Centre Maribor.Methods: We reviewed the documentation of ten patients treated for jugular paraganglioma in the last 15 years, and presented the clinical data in a table.Results: Nine patients were treated by preoperative embolization and surgical resection. Surgery was contraindicated in one patient with highly dominant venous drainage on the side of the tumor and aplastic transverse sinus on the opposite side. She was treated by primary radiotherapy. One patient with intracranial tumor growth was treated by subtotal resection and adjuvant radiotherapy. At presentation, lower cranial nerve palsies were present in 60 % of our patients. With the other 40 % we managed to preserve the nerve function postoperatively. Facial nerve function practically normalized in all patients with anterior transposition of the nerve. Our patients were provided with postoperative rehabilitation and corrective procedures such as vocal cord medialization and BAHA hearing aid implantation.Discussion: Despite the risks, the surgical treatment is effective in halting the disease and preserving cranial nerve function. The results of our work demonstrate that our patients are provided with a thorough and comprehensive care.

Introduction: Jugular foramen tumor is a rare tumor. Jugular foramen schwannoma is rarer. This type of tumor may present in combination of different cranial nerve palsies in the form of different syndromes or may also be diagnosed incidentally. Management of such tumor is not straight forward.Case reports: Two young male presented with headache, vomiting, gait instability, right sided hearing loss. Clinically they had different cranial nerves dysfunction. Imaging showed jugular foramen tumor extending from posterior fossa to almost common carotid bifurcation at neck in both cases. Near total microsurgical excisions of the tumor were done through retrosigmoid suboccipital plus transmastoid high cervical approach with facial nerve mobilization in one case and without mobilization in other case. In case 1 combination of lower cranial nerve palsies is unique with inclusion of VIII nerve and that does not belong to any of the jugular foramen syndromes (i.e. Vernet, Collet- Sicard, Villaret, Tapia, Schmidt, and Jackson). Here IX, X, XI, XII and VIII cranial palsies was present (i.e.Collet-Sicard syndrome plus VIII nerve syndrome!). In the second case there was IX & X dysfunction with VIII dysfunction.

ABSTRACT:Dysarthria, dysphagia and repeated aspiration in a 54-year-old woman diagnosed and treated for myasthenia gravis 7 years earlier were initially thought to represent a late exacerbation of myasthenia. A cervical mass invading the jugular foramen and causing multiple lower cranial nerve palsies was biopsied and found to represent invasive ectopic thymoma.

Condyle Fracture

Abstract Background Multiple lower cranial nerve palsies have been attributed to occipital condyle fractures in older children and adults, but no clinical details of other possible mechanisms have been described in infants. Case Report A 33-month-old boy suffered blunt head trauma. A bilateral skull base fracture was diagnosed, with favorable outcome during the first days after trauma. On the sixth day, the patient began to refuse drinking and developed hoarseness. Physical examination and additional investigations revealed paralysis of left VII, IX, X, and XI cranial nerves. A follow-up computed tomography (CT) scan disclosed a left petrous bone fracture involving the lateral margin of the jugular foramen, and a cranial magnetic resonance imaging (MRI) study showed a left cerebellar tonsil contusion. He improved after methylprednisolone was started. Three months later, he was asymptomatic, although mild weakness and atrophy of the left sternocleidomastoid and trapezius muscles remained 1 year later. Discussion A posttraumatic “jugular foramen syndrome” is rare in children, but it has been reported shortly after occipital condyle fracture, affecting mainly IX, X, and XI cranial nerves. In this toddler, delayed symptoms appeared with unilateral involvement. While an occipital fracture was ruled out, neuroimaging findings suggest the hypothesis of a focal contusion as a consequence of a coup-contrecoup injury. Conclusion This exceptional case highlights the importance of gathering physical examination, anatomical correlation, and neuroimaging to yield a diagnosis.

Abstract Objectives This study aimed to demonstrate resection of a craniovertebral junction (CVJ) meningioma via the posterolateral approach. Design The study is designed with a two-dimensional operative video. Setting This study is conducted at department of neurosurgery in a university hospital. Participants A 50-year-old woman who presented with lower cranial nerve findings due to a left-sided lower clival meningioma (Fig. 1). Main Outcome Measures Microsurgical resection of the meningioma and preservation of the neurovascular structures. Results The patient was placed in park-bench position and a left-sided retrosigmoid suboccipital craniotomy, followed by C1 hemilaminectomy and unroofing the lip of the foramen magnum, was performed. The dural incision extended from the suboccipital region down to the posterior arch of C2 (Fig. 2). The arachnoid overlying the tumor was incised, revealing the course of the cranial nerve (CN) XI on the dorsolateral aspect of the tumor. The left vertebral artery (VA) was encased by the tumor which was originating from the dura below the jugular foramen. The mass was resected in a piecemeal fashion eventually. At the end of the procedure, all relevant cranial nerves and adjacent vascular structures were intact. Postoperative magnetic resonance imaging (MRI) confirmed total resection and the patient was discharged home on postoperative day 3 safely. Conclusions Microsurgical resection of the lesions of the CVJ are challenging as this transition zone between the cranium and upper cervical spine has a complex anatomy. Since adequate exposure of the extradural and intradural segments of the VA can be obtained by the posterolateral approach, this approach can be preferred in cases with tumors anterior to the VA or when the artery is encased by the tumor.The link to the video can be found at: https://youtu.be/d3u5Qrc-zlM.

The Individual

In this retrospective study, oncologic and functional results of 46 patients treated for glomus jugulare tumor are reported. The standard surgical approach was the combined transmastoid-transcervical approach, modified according to the individual tumor growth, and eventually combined with a transtemporal or a suboccipital approach. Complete tumor removal resulted in a cure rate of 90%. New-onset cranial nerve palsies developed in less than 22% of patients. In 54% of cases it was possible to retain middle ear function. From a total of 12 patients with incomplete tumor removal and postoperative irradiation, progressive tumor growth was noted in 4 patients, and was controlled by salvage irradiation or surgery. Radical tumor removal by ablative surgery can be modified by efforts to reduce mutilating resections. In their place, individually tailored and combined multidirectional surgical approaches may allow total tumor removal with lower morbidity.

Internal carotid dissection most commonly presents as headache, focal neurological deficits or stroke. Rarely it can manifest itself by causing a palsy of the lower cranial nerves (IX, X, XI, XII). The reported incidence of isolated cranial nerve palsies is rare. We report a case of an internal carotid artery dissection manifesting as isolated XII (hypoglossal) cranial nerve palsy.

<b><i>Introduction:</i></b> A number of neurological complications of COVID-19 have been identified, including cranial nerve paralyses. We present a series of 10 patients with lower cranial nerve involvement after severe COVID-19 infection requiring hospitalization in an intensive care unit. <b><i>Methods:</i></b> We conducted a retrospective, observational study of patients admitted to the post-intensive care unit (p-ICU) of Besançon University Hospital (France) between March 16 and May 22, 2020. We included patients with confirmed COVID-19 and cranial neuropathy at admission to the p-ICU. All these patients were treated by orotracheal intubation, and all but one underwent prone-position ventilation therapy. <b><i>Results:</i></b> Of the 88 patients admitted to the p-ICU, 10 patients (11%) presented at least 1 cranial nerve palsy. Of these 10 patients, 9 had a hypoglossal nerve palsy and 8 of these also had a deficit in another cranial nerve. The most frequent association was between hypoglossal and vagal palsies (5 patients). None of the patients developed neurological signs related to a global neuropathy. We found no correlation between the intensity of the motor limb weakness and the occurrence of lower cranial nerve palsies. All but 2 of the patients recovered within less than a month. <b><i>Conclusion:</i></b> The mechanical compressive hypothesis, linked to the prone-position ventilation therapy, appears to be the major factor. The direct toxicity of SARS-CoV-2 and the context of immune dysfunction induced by the virus may be involved in a multifactorial etiology.

ABSTRACT Background and Objectives: Neurinoma arising from other than nonvestibular cranial nerves is less prevalent. Here we present our experiences regarding the clinical profile, investigations, microneurosurgical management, and the outcome of nonvestibular cranial nerve neurinomas. Materials and Methods: From January 2005 to December 2011, the recorded documents of operated nonvestibular intracranial neurinomas were retrospectively studied for clinical profile, investigations, microneurosurgical management, complications, follow-up, and outcomes. Results: The average follow-up was 24.5 months. Total number of cases was 30, with age ranging from 9 to 60 years. Sixteen cases were males and 14 were females. Nonvestibular cranial nerve schwannomas most commonly originated from trigeminal nerve followed by glossopharyngeal+/vagus nerve. There were three abducent nerve schwannomas that are very rare. There was no trochlear nerve schwannoma. Two glossopharyngeal+/vagus nerve schwannomas extended into the neck through jugular foramen and one extended into the upper cervical spinal canal. Involved nerve dysfunction was a common clinical feature except in trigeminal neurinomas where facial pain was a common feature. Aiming for no new neurodeficit, total resection of the tumor was done in 24 cases, and near-total resection or gross total resection or subtotal resection was done in 6 cases. Preoperative symptoms improved or disappeared in 25 cases. New persistent deficit occurred in 3 cases. Two patients died postoperatively. There was no recurrence of tumor till the last follow-up. Conclusion: Nonvestibular schwannomas are far less common, but curable benign lesions. Surgical approach to the skull base and craniovertebral junction is a often complex and lengthy procedure associated with chances of significant morbidity. But early diagnosis, proper investigations, and evaluation, along with appropriate decision making and surgical planning with microsurgical techniques are the essential factors that can result in optimum outcome.

Object. Electromyography (EMG) monitoring is expected to reduce the incidence of motor cranial nerve deficits in cerebellopontine angle surgery. The aim of this study was to provide a detailed analysis of intraoperative EMG phenomena with respect to their surgical significance.Methods. Using a system that continuously records facial and lower cranial nerve EMG signals during the entire operative procedure, the authors examined 30 patients undergoing surgery on acoustic neuroma (24 patients) or meningioma (six patients). Free-running EMG signals were recorded from muscles targeted by the facial, trigeminal, and lower cranial nerves, and were analyzed off-line with respect to waveform characteristics, frequencies, and amplitudes. Intraoperative measurements were correlated with typical surgical maneuvers and postoperative outcomes.Characteristic EMG discharges were obtained: spikes and bursts were recorded immediately following the direct manipulation of a dissecting instrument near the cranial nerve, but also during periods when the nerve had not yet been exposed. Bursts could be precisely attributed to contact activity. Three distinct types of trains were identified: A, B, and C trains. Whereas B and C trains are irrelevant with respect to postoperative outcome, the A train—a sinusoidal, symmetrical sequence of high-frequency and low-amplitude signals—was observed in 19 patients and could be well correlated with additional postoperative facial nerve paresis (in 18 patients).Conclusions. It could be demonstrated that the occurrence of A trains is a highly reliable predictor for postoperative facial palsy. Although some degree of functional worsening is to be expected postoperatively, there is a good chance of avoiding major deficits by warning the surgeon early. Continuous EMG monitoring is superior to electrical nerve stimulation or acoustic loudspeaker monitoring alone. The detailed analysis of EMG-waveform characteristics is able to provide more accurate warning criteria during surgery.
