J Korean Neurosurg Soc 2024; 67:122-129. [PMID: 37643721 PMCID: PMC10788546 DOI: 10.3340/jkns.2022.0273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 02/27/2023] [Accepted: 04/17/2023] [Indexed: 08/31/2023] Open
Abstract
Paragangliomas are rare neuroendocrine tumors that are usually benign in nature. They may be either familial or sporadic in their occurrence. Numerous neuroendocrine tumors are collectively included under the umbrella of paragangliomas. Among them, carotid body tumors and glomus jugulare tumors are extremely rare. Thus, we present a rare case of 29-year-old male who was admitted with hearing difficulties and tinnitus in the left ear, with swelling on the left side of the neck. Based on clinical and radiological findings, a diagnosis of left-sided glomus jugulare with carotid body tumor was made. The patient underwent a twostage surgery with an interval of approximately 2 months. Histopathology revealed a paraganglioma. Herein, we present the clinical features, imaging findings, management, and a brief review of literature on the classification, evaluation, and management of carotid body and glomus jugulare tumors. Paraganglioma is a slow-growing tumor. The synchronous occurrence of carotid body and glomus jugulare tumors is infrequent. Microsurgical resection remains the primary treatment modality. Therefore, our patient underwent two-stage surgery. The rarity of occurrence and the proximity and adherence to vital neurovascular structures have resulted in the treatment of paragangliomas remaining a challenge.

Abstract
To analyse and report various aspects of lateral skull base surgery by describing the incidence and demographic variables, diagnostic and management challenges, surgical choices along with complications and their management and the long term morbidity and survival outcomes in our experience of 15 years. Retrospective review of complete records of all cases operated for lateral skull base tumors at a tertiary care teaching institution in India between timespan of 15 years from 2003 to 2018 was undertaken. 53 cases were selected and analysed. Those having follow up of less than 6 months were excluded. Outcomes were assessed in terms of incidence of types of tumors, benign or malignant, age and sex variation of the patients, staging status at presentation, status of facial and other lower cranial nerves pre-operatively, surgical techniques with complications if any, recurrences and survival. Of 35 benign tumors, tympanojugular paragangliomas were most common. Average age for these was 53 years with 19 females and 14 males. All were non-functional. Tinnitus and hearing loss were most common presentations. Class B2 and C1 tumors were most commonly encountered and the ITF A approach was most commonly used. Hearing loss and Facial palsy were commonest complication post-operatively. There were 2 recurrences. 18 malignancies were observed. Most were stage IV at presentation. Otorrhea and otalgia were most common presenting symptoms followed by hearing loss. 5 year survival was 55%. Successful treatment of lateral skull base lesions requires a multimodality therapy with team approach. Surgical resection is the primary management choice with variable approaches. ICA status related to the tumor is the most important consideration. Malignancies require more aggressive treatment for obtaining clear margins along with pre/post-op chemoradiation. Good results with acceptable complications can be obtained even with advanced tumors.

Abstract
OBJECTIVE To compare preoperative and postoperative lower cranial nerve (LCN) function between Class C1 and C2 tympanojugular paraganglioma (TJP) with/without intracranial intradural (Di)/extradural (De) extensions, according to the experience of a single surgeon over four decades. STUDY DESIGN Retrospective review. SETTING Quaternary referral center for otology and skull base surgery. MATERIAL AND METHODS A chart review was conducted of all the patients operated for C1/C2 TJPs from September 1983 to December 2018. The tumors were classified as: Limited-Group (C1/C2 without Di/De extensions) and Extended-Group (C1/C2 with Di/De extensions). RESULTS Of 159 patients, 107 (67.3%) were women; the mean age at surgery was 46.5 years. The Limited-Group (56.6%) comprised C1 (41.1%) and C2 (58.9%) tumors; the Extended-Group (43.4%) comprised C1+Di/De (14.5%) and C2+Di/De (85.5%) tumors. The prevalence of preoperative LCN palsy was 11.9 times higher in Extended than Limited tumors: 61.9% versus 4.9% (p < 0.05). The risk for postoperative LCN palsy was 4.7 times greater in Extended than Limited tumors: 29.2% versus 12.9%, p = 0.01. CONCLUSION Especially in younger patients, complete removal of Limited C1/C2 tumors, before they extend intracranially, reduces the risk of dysfunctionality of LCNs and the burden of residual tumor. The incidence of new tumors increased over four decades. However, new-postoperative LCN palsy did not occur in any Limited C1/C2 tumors operated after the year 2000, and declined to less than 10% of Extended C1/C2 tumors.

Abstract
<br><b>Introduction:</b> Injuries of the carotid artery constitute a rare group of injuries. This study presents results of the treatment of 44 patients with iatrogenic carotid artery injuries for over 20 years. The patients were treated by the team of doctors of the Department of Vascular, General and Transplant Surgery in Wroclaw in the years 1997–2017 (Head of the Department Prof. Klemens Skóra, MD, and Prof. Piotr Szyber, MD, PhD – material used with permission).</br>
<br><b>Aim:</b> Aims of the analysis are: to estimate the frequency of different forms of iatrogenic injuries to the common and internal carotid artery, to evaluate the results of treatment, to assess the most effective surgical method depending on the type of injury, and develop an effective preoperative, intraoperative and postoperative regimen.</br>
<br><b>Discussion and results:</b> The frequency of various carotid artery injuries (blunt, acute, traffic) was constant between years, but the number of iatrogenic injuries definitely increased over time. The prognosis for patients with carotid artery injury, especially when combined with multi-organ trauma, is the gravest. Significantly better treatment results were achieved with both acute and iatrogenic injuries. This is mainly due to easier and quicker diagnosis and better conditions for assisting patients.</br>
<br><b>Conclusions:</b> In iatrogenic injuries, a well-designed surgical scheme, i.e. primarily the administration of UTH and placing a temporary suction drain by the first operating team, reduces the risk of neurological complications.</br>

Diameter-Based Volumetric Models May Inadequately Calculate Jugular Paraganglioma Volume Following Sub-Total Resection. Otol Neurotol 2021; 42:e1339-e1345.

Abstract
BACKGROUND As gross total resection of jugular paragangliomas (JPs) may result in cranial nerve deficits, JPs are increasingly managed with subtotal resection (STR) with postoperative radiological monitoring. However, the validity of commonly used diameter-based models that calculate postoperative volume to determine residual tumor growth is dubious. The purpose of this study was to assess the accuracy of these models compared to manual volumetric slice-by-slice segmentation. METHODS A senior neuroradiologist measured volumes via slice-by-slice segmentation of JPs pre- and postoperatively from patients who underwent STR from 2007 to 2019. Volumes from three linear-based models were calculated. Models with absolute percent error (APE) > 20% were considered unsatisfactory based on a common volumetric definition for residual growth. Bland-Altman plots were used to evaluate reproducibility, and Wilcoxon matched-pairs signed rank test evaluated model bias. RESULTS Twenty-one patients were included. Median postoperative APE exceeded the established 20% threshold for each of the volumetric models as cuboidal, ellipsoidal, and spherical model APE were 63%, 28%, and 27%, respectively. The postoperative cuboidal model had significant systematic bias overestimating volume (p = 0.002) whereas the postoperative ellipsoidal and spherical models lacked systematic bias (p = 0.11 and p = 0.82). CONCLUSION Cuboidal, ellipsoidal, and spherical models do not provide accurate assessments of postoperative JP tumor volume and may result in salvage therapies that are unnecessary or inappropriately withheld due to inaccurate assessment of residual tumor growth. While more time-consuming, slice-by-slice segmentation by an experienced neuroradiologist provides a substantially more accurate and precise measurement of tumor volume that may optimize clinical management.

Abstract
BACKGROUND The cerebellopontine angle (CPA) is a narrowed skull base area containing important cranial nerves and vessels and bordering with eloquent areas of the posterior fossa. Tumors of the CPA are a heterogeneous group and can have extradural, intradural/extra-axial, or intra-axial origins. Their vascular supply changes depending on their anatomic origin. Symptomatic, large CPA tumors require surgical resection in order to prevent irreversible, severe neurological damages. However, its tight and strategical location make surgery in the CPA very challenging and require appropriate pre-surgical planning. Pre-surgical diagnosis is of great importance as it allows us to choose the optimal management for the particular patient. This is of further significance when encountering high-risk lesions such as hypervascular tumors. Neurosurgeons should utilize every available pre-surgical diagnostic modalities as well as neo-adjuvant treatments in order to reduce such risks. METHODS We review all reported cases of hypervascular lesions of the CPA and discuss the roles of angiography and stereotactic radiosurgery in their management. RESULTS Three lesions of the CPA can be considered as truly hypervascular: hemangioblastomas, hemangiopericytomas and paragangliomas. All lesions share many radiological features. However, each lesion has a different anatomical origin and hence, has a characteristic vascular supply. Pre-surgical angiography can be utilized as a diagnostic tool to narrow down the differential diagnosis of a vascular CPA lesion, based on the predominant supplying vessel. In addition, pre-surgical embolization at time of angiography will narrow the associated surgical risks. CONCLUSIONS Angiography is a crucial diagnostic and therapeutic tool, helping both in narrowing the presurgical differential diagnosis and in controlling intraoperative bleeding. Because of the high surgical risks associated with resection of vascular tumors in the CPA, noninvasive treatments, such as stereotactic radiosurgery, also may have a crucial role.

Abstract
OBJECTIVE The aim of this study was to analyze the neurological functional outcome and recurrent risks in surgically treated jugular foramen paragangliomas (JFPs) and to propose an individualized therapeutic strategy. METHODS Clinical charts and radiological information were reviewed retrospectively in 51 consecutive cases of JFPs. Less-aggressive surgical interventions were adopted with the goal of preserving neurovascular structures. Scheduled follow-up was performed. RESULTS The mean age of the patients in the cases reviewed was 41.6 years, and the group included 27 females (52.9%). The mean preoperative Karnofsky Performance Scale (KPS) score was 78.4. The mean lesion size was 3.8 cm. Forty-three cases (84.3%) were Fisch Type D, including 37 cases (72.5%) of Type Di1 and Di2. Thirty-seven cases (72.5%) were Glasscock-Jackson Type III-IV. Gross-total resection and subtotal resection were achieved in 26 (51.0%) and 22 (43.1%) cases, respectively. Surgical morbidities occurred in 23 patients (45.1%), without surgery-related mortality after the first operation. The mean postoperative KPS scores at discharge, 3 months, 1 year, and most recent evaluation were 71.8, 77.2, 83.2, and 79.6, respectively. The mean follow-up duration was 85.7 months. The tumor recurrence/regrowth (R/R) rate was 11.8%. Compared with preoperative status, swallowing function improved or stabilized in 96.1% and facial function improved or stabilized in 94.1% of patients. A House-Brackmann scale Grade I/II was achieved in 43 patients (84.3%). Overall neurological status improved or stabilized in 90.0% of patients. Pathological mitosis (HR 10.640, p = 0.009) was the most significant risk for tumor R/R. A 1-year increase in age (OR 1.115, p = 0.037) and preoperative KPS score < 80 (OR 11.071, p = 0.018) indicated a risk for recent poor neurological function (KPS < 80). Overall R/R-free survival, symptom progression-free survival, and overall survival at 15 years were 78.9%, 86.8%, and 80.6%, respectively. CONCLUSIONS Surgical outcomes for JFPs were acceptable using a less-aggressive surgical strategy. Most patients could adapt to surgical morbidities and carry out normal life activities. Preserving neurological function was a priority, and maximal decompression with or without radiotherapy was desirable to preserve a patient's quality of life when radical resection was not warranted. Early surgery plus preoperative devascularization was proposed, and radiotherapy was mandatory for lesions with pathological mitosis.

Abstract
The aim of this study was to report the postoperative lower cranial nerves (LCNs) function in patients undergoing surgery for tympanojugular paraganglioma (TJP) and to evaluate risk factors for postoperative LCN dysfunction. A retrospective case review of 122 patients having Fisch class C or D TJP, surgically treated from 1988 to 2012, was performed. The follow-up of the series ranged from 12 to 156 months (mean, 39.4 ± 32.6 months). The infratemporal type A approach was the most common surgical procedure. Gross total tumor removal was achieved in 86% of cases. Seventy-two percent of the 54 patients with preoperative LCN deficit had intracranial tumor extension. Intraoperatively, LCNs had to be sacrificed in 63 cases (51.6%) due to tumor infiltration. Sixty-six patients (54.09%) developed a new deficit of one or more of the LCNs. Of those patients who developed new LCN deficits, 23 of them had intradural extension. Postoperative follow-up of at least 1 year showed that the LCN most commonly affected was the CN IX (50%). Logistic regression analysis showed that intracranial transdural tumor extension was correlated with the higher risk of LCN sacrifice (p < 0.05). Despite the advances in skull base surgery, new postoperative LCN deficits still represent a challenge. The morbidity associated with resection of the LCNs is dependent on the tumor's size and intradural tumor extension. Though no recovery of LCN deficits may be expected, on long-term follow-up, patients usually compensate well for their LCNs loss.

Abstract
Paragangliomas (PGLs) are tumours originating from neural crest-derived cells situated in the region of the autonomic nervous system ganglia. Head-and-neck PGLs (HNPGLs) originate from the sympathetic and parasympathetic paraganglia, most frequently from the carotid bodies and jugular, tympanic and vagal paraganglia, and are usually non-catecholamine secreting. Familial PGLs are considered to be rare, but recently genetic syndromes including multiple PGLs and/or phaeochromocytomas have been more thoroughly characterised. Nowadays, genetic screening for the genes frequently implicated in both familial and sporadic cases is routinely being recommended. HNPGLs are mostly benign, generally slow-growing tumours. Continuous growth leads to the involvement of adjacent neurovascular structures with increased morbidity rates and treatment-related complications. Optimal management mostly depends on tumour location, local involvement of neurovascular structures, estimated malignancy risk, patient age and general health. Surgery is the only treatment option offering the chance of cure but with significant morbidity rates, so a more conservative approach is usually considered, especially in the more difficult cases. Radiotherapy (fractionated or stereotactic radiosurgery) leads to tumour growth arrest and symptomatic improvement in the short term in many cases, but the long-term consequences are unclear. Early detection is essential in order to increase the chance of cure with a lower morbidity rate. The constant improvement in diagnostic imaging, surgical and radiation techniques has led to a safer management of these tumours, but there are still many therapeutic challenges, and no treatment algorithm has been agreed upon until now. The management of HNPGLs requires a multidisciplinary effort addressing the genetic, surgical, radiotherapeutic, oncological, neurological and endocrinological implications. Further progress in the understanding of their pathogenesis will lead to more effective screening and earlier diagnosis, both critical to successful treatment.

Abstract
Objective The objective of this study is to discuss the management of advanced glomus jugulare tumors (GJTs) presenting with intradural disease and concurrent brainstem compression. Study Design This is a retrospective case series. Results Over the last decade, four patients presented to our institution with large (Fisch D2; Glasscock-Jackson 4) primary or recurrent GJTs resulting in brainstem compression of varying severities. All patients underwent surgical resection through a transtemporal, transcervical approach resulting in adequate brainstem decompression; the average operative time was 12.75 hours and the estimated blood loss was 2.7 L. All four patients received postoperative adjuvant radiotherapy in the form of intensity-modulated radiation therapy or stereotactic radiosurgery. Combined modality treatment permitted tumor control in all patients (range of follow-up 5 to 9 years). Conclusion A small subset of GJTs may present with intracranial transdural extension with aggressive brainstem compression mandating surgical intervention. Surgical resection is extremely challenging; the surgical team must be prepared for extensive operating time and the patient for prolonged aggressive rehabilitation. Newly diagnosed and recurrent large GJTs involving the brainstem may be controlled with a combination of aggressive surgical resection and postoperative radiation.

Abstract
BACKGROUND The definitive treatment for head and neck paraganglioma (PG) is surgical excision. Unfortunately, surgery, particularly of vagal paraganglioma (VPG; "glomus vagale") and foramen jugulare ("glomus jugulare") tumors, may be complicated by injuries to the lower cranial nerves, a high price to pay for treatment for a benign tumor. Alternatively these tumors may be followed without treatment, or irradiated. The purpose of this review was to compare the existing evidence concerning the efficacy and safety of surgery, external beam radiotherapy (EBRT), and stereotactic radiosurgery (SRS), for jugular paragangliomas (JPGs) and VPGs. METHODS Relevant articles were reviewed using strict criteria for systematic searches. Forty-one surgical studies met the criteria which included 1310 patients. Twenty articles including 461 patients treated with EBRT, and 14 radiosurgery studies comprising 261 patients were also evaluated. Results were compared between treatment modalities using analysis of variance (ANOVA) tests. RESULTS A total of 1084 patients with JPGs and 226 VPGs were treated with different surgical procedures. Long-term control of the disease was achieved in 78.2% and 93.3% of patients, respectively. A total of 715 patients with JPG were treated with radiotherapy: 461 with EBRT and 254 with SRS. Control of the disease with both methods was obtained in 89.1% and 93.7% of the patients, respectively. The treatment outcomes of a JPG treated with surgery or radiotherapy were compared. Tumor control failure, major complication rates, and the number of cranial nerve palsies after treatment were significantly higher in surgical than in radiotherapy series. The results of SRS and EBRT in JPGs were compared and no significant differences were observed in tumor control. Because only 1 article reported on the treatment of 10 VPGs with radiotherapy, no comparisons with surgery could be made. Nevertheless, the vagus nerve was functionally preserved in only 11 of 254 surgically treated patients (4.3%). CONCLUSION There is evidence that EBRT and SRS offer a similar chance of tumor control with lower risks of morbidity compared with surgery in patients with JPGs. Although the evidence is based on retrospective studies, these results suggest that surgery should be considered only for selected cases, but the decision should be individual for every patient.

Abstract
BACKGROUND AND PURPOSE The applied approach to the jugular foramen is a combination of the juxtacondylar approach with the subtemporal fossa approach type A. The purpose of this study is to present our results of treatment of jugular paragangliomas using the aforementioned approach. MATERIAL AND METHODS Twenty-one patients (15 women, 6 men) with jugular paragangliomas were included in the study. The neurological status of the patients was assessed before and after surgery as well as at the conclusion of treatment. The approximate volume of the tumour, its relation to large blood vessels, cranial nerves and brainstem, as well as consistency and vascularity were also assessed. RESULTS The duration of symptoms ranged from 3 to 74 months. In 86% of patients hearing loss was the predominant symptom. The less frequent symptoms included pulsatile tinnitus in the head, dysphagia and dizziness. Approximate volume of the tumours ranged from 2 to 109 cm3. A gross total resection was achieved in 71.5% of patients. The postoperative performance status improved in 38% of patients, did not change in 38% and deteriorated in 24% of patients. CONCLUSIONS A proper selection of the range of the approach to jugular foramen paragangliomas based on their topography and volume reduces perioperative injury without negative consequences for the radicality of the resection.

Abstract
As it became clear that patients with paraganglioma (PGL) syndromes had a higher risk of multifocal tumors, we changed our surgical strategy to avoid the possibility of bilateral cranial nerve paralysis. The juxtacondylar approach offers advantages for some jugular foramen tumors, including types C and D temporal PGLs. This approach allows exposure of the jugular foramen without skeletonizing or transposing the facial nerve. It improves the surgeon's ability to distinguish between the pars vascularis and the pars nervosa at the jugular foramen, and it helps to save functioning of the lower cranial nerves. There is already considerable experience using the juxtacondylar approach for patients suffering from schwannomas and meningiomas involving the jugular foramen. Some limitations have been noted for using the juxtacondylar approach with jugular PGLs that are related to their vascular nature. In this article we demonstrate its use for the management of eight patients with locally advanced temporal PGLs and how it can be combined with an infratemporal fossa approach.

Abstract
ABSTRACT
Paragangliomas or glomus tumors are usually low-grade hypervascular tumors occurring in various sites of the autonomic nervous system including the carotid body, glomus vagale and glomus tympanicum. Although the grading of the tumor suggests a benign clinical course, the tumor can be locally malignant and surgical management is sometimes difficult because of postoperative functional loss and local recurrence. In addition, the operative field is generally very bloody and tissue planes are not always well-defined.
Though the optimal management of paraganglioma occurs in a multidisciplinary setting, considering the excellent local control rates with primary irradiation alone, a nonsurgical definitive approach should initially be considered.

Abstract
To determine the clinical features, investigations, intra-operative findings, surgical approaches used and the results of the treatment for paragangliomas of the head and neck. Retrospective study of 14 cases of paragangliomas in head and neck seen over a period of 10 years including five carotid body tumors, seven glomus jugulares and two glomus tympanicums. HRCT scans and bilateral carotid angiography were done in all cases of glomus jugulare. Pre-operative embolization was done in most cases. The trans-cervical approach was used for all cases of carotid body. In three cases of Type B jugulare tumors, a post-aural tympanotomy was used. A Fisch Type A approach was done for three cases of Type D jugulare tumors. Postaural tympanotomy approach was used for both patients with glomus tympanicum. In one case of extratympanic glomus jugulare tumor with hypoglossal palsy, a neck exploration was done to isolate and excise the tumor. Five patients with carotid body tumors presented as unilateral, painless, pulsatile swelling in the upper neck. Intra-operatively, three of the tumors were classified into Shamlin's Grade II and one each into Grade III and Grade I. A carotid blow-out occurred in one of the patients with Grade II disease, which was managed. ECA resection had to be done in one case. Seven patients were diagnosed to have glomus jugulare and two with glomus tympanicum. Six glomus jugulare tumors presented with hearing loss, ear discharge and obvious swelling. Glomus tympanicums presented with hearing loss but no bleeding from the ear. On examination, tumors presented with an aural polyp with no VII nerve deficits. Both tympanicums were classified as Fisch Type A, three of the jugulares classified as Type B, two as Type D2 and one as Type D1. Tumors were found to be supplied predominantly by the ascending pharyngeal artery. In three cases of Type B jugulare tumors, a post-aural tympanotomy was used. A Fisch Type A approach was done for three cases of Type D jugulare. The transcanal approach was used for both patients with glomus tympanicum. Paragangliomas are uncommon tumors that need accurate diagnosis and skilled operative techniques. Though the surgical approaches may appear complicated, the removal provides good cure rates with minimal morbidity and recurrence. Lateral skull base approaches should be the armamentarium of every head and neck surgeon.

Abstract
UNLABELLED Descriptive retrospective study of 14 patients with paragangliomas (PGL) attended in the University Hospital of Vigo (Pontevedra) during the last 25 years to evaluating their characteristics and neuroendocrine potential. RESULTS 71.4% were diagnosed due to mass tumoral effect, 21.4% due to adrenergic symptoms and 7.1% incidentally. Regarding to symptoms and signs 66.7% of PGL Simpatic (PGLS) and 40% of PGL Parasimpatic (PGLPS) presented adrenergic symptoms. Urine catecholamine analysis was carried out to 4 PGLS and high levels were found in all patients. The tumoral size reached a mean value of 37.8+/-18.9 mm, there were not differences found between both types of tumors. Inmunohistoquimia showed positive Chromogranine A stain in all patients. Two PGLS were maligns. Eleven patients had positive outcome, 2 PGLS died, and 1 PGLPS remains not cured. CONCLUSIONS High percentage of patients had clinical manifestations related to catecholamine hyperproduction. We believe that due to the risk related to surgical treatment, malignance, multiple location and family associations, it would be advisable to carry out a complete examination prior to surgery.

Abstract
Intrasellar paragangliomas are very rare lesions with only six previous cases described in the literature. We present a further case of intrasellar paraganglioma. The patient was a 52 yr-old man who developed two transient ischemic attacks. A CT scan showed an intra- and supra-sellar expanding lesion, which was regarded as a possible non-functioning pituitary macro-adenoma. Removal of the lesion was accomplished by transsphenoidal surgery. Histological examination was diagnostic of a paraganglioma. We review the literature and discuss pathological features and possible pathogenesis of sellar and parasellar paragangliomas, underlining the necessity to consider paraganglioma in the differential diagnosis of sellar lesions.

Abstract
Majority of the cerebellopontine angle (CPA) tumors are acoustic neuromas, while bulk of the non-acoustic tumors are formed by meningiomas and epidermoid cysts. Primary paraganglioma is a rare tumor in this location, with only two such cases having been reported in the literature, till date. Recently, a case has been described wherein a paraganglioma was apparently arising as a primary lesion in the cerebellar hemisphere. We report another case of an intracranial paraganglioma of the CPA in a 40-year-old female, which did not have any vascular attachment but had focal cerebellar extension.

Abstract
Paragangliomas of the head and neck are highly vascular lesions originating from paraganglionic tissue located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas). Diagnostic imaging can be considered in two clinical situations: (1) patients who present with clinical symptoms suggestive of a paraganglioma, and (2) individuals from families with hereditary paragangliomas. It is not only necessary to detect and characterize the lesion, but also to study the presence of multiplicity. For these purposes, MR imaging, and especially 3D TOF MRA, is the modality of choice. CT scanning is especially useful to show destruction of the temporal bone. Angiography in combination with embolization will mainly be used prior to surgical resection, but can also be used for diagnostic purposes when the diagnosis is not yet clear. Many parameters play a role in the decision to treat of which multifocality and impairment of cranial nerves are the most important. The primary therapeutic option for paragangliomas is complete excision of tumor with preservation of vital neurovascular structures. Resection however, should be balanced against a more conservative "wait and scan" policy or palliative treatments such as radiotherapy.

Abstract
The use of skull base techniques in the treatment of benign skull base tumors has allowed access to areas of the brain once considered inaccessible. The most common benign skull base tumors encountered in neurosurgical practice are benign meningiomas, schwannomas, and glomus jugulare tumors. Gross total resection of these lesions gives patients the best possible chance of a cure. In this paper, we review the rationale for the use of skull base surgery techniques for benign skull base tumors.

Abstract
Paragangliomas of the head and neck are preferably treated surgically. Planning the surgical approach for temporal bone paragangliomas is performed according to the Fisch classification. Small temporal paragangliomas can be removed in a transtympanic or transmastoidal procedure. Locally advanced paragangliomas of the head and neck have to be embolized presurgically. An occlusion test is also recommended to check the possibility of a resection of the internal carotid artery. Type C and D temporal bone paragangliomas can be removed by different infratemporal approaches. Alternatively, some type C(1,2 )and De,i(1,2) temporal bone paragangliomas can be removed via variations of the juxtacondylar approach. Glomus caroticum tumors are resected transcervically. In cases of contraindications for surgery or in palliative situations radiotherapy is recommended.

Abstract
Object
Tumors of the glomus jugulare are benign, slow-growing paragangliomas. Their natural history, surgical treatment, and outcome have been well addressed in the recent literature; however, there remains a subgroup of complex tumors—multiple, giant, malignant, neuropeptide-secreting lesions, and those treated previously by an intervention with an adverse outcome—that is high risk, presents surgical challenges, and is associated with treatment controversy. In this article the authors report on a series of patients with complex glomus jugulare tumors and focus on treatment decisions, avoidance of complications, surgical refinements, and patient outcomes.
Methods
In this retrospective study, the patient population was composed of 11 male and 32 female patients (mean age 47 years) with complex tumors of the glomus jugulare who were treated by the senior author within the past 20 years. These include 38 patients with giant tumors, 11 with multiple paragangliomas (seven bilateral and four ipsilateral), two with tumors that hypersecreted catecholamine, and one with a malignant tumor. Six patients had associated lesions: one dural arteriovenous malformation, one carotid artery (CA) aneurysm, two adrenal tumors, and two other cranial tumors.
All but one patient presented with neurological deficits. Cranial nerve deficits, particularly those associated with the lower cranial nerves, were the prominent feature. Twenty-eight patients underwent resection in an attempt at total removal, and gross-total resection was achieved in 24 patients. Particularly challenging were cases in which the patient had undergone prior embolization or CA occlusion, after which new feeding vessels from the internal CA and vertebrobasilar artery circulation developed.
The surgical technique was tailored to each patient and each tumor. It was modified to preserve facial nerve function, particularly in patients with bilateral tumors. Intrabulbar dissection was performed to increase the likelihood that the lower cranial nerves would be preserved. Each tumor was isolated to improve its resectability and prevent blood loss. No operative mortality occurred. In one patient hemiplegia developed postoperatively due to CA thrombosis, but the patient recovered after an endovascular injection of urokinase. In four patients a cerebrospinal fluid leak was treated through spinal drainage, and in five patients infection developed in the external ear canal. Two of these infections progressed to osteomyelitis of the temporal bone. There were two recurrences, one in a patient with a malignant tumor who eventually died of the disease.
Conclusions
Despite the challenges encountered in treating complex glomus jugulare tumors, resection is indicated and successful. Multiple tumors mandate a treatment plan that addresses the risk of bilateral cranial nerve deficits. The intra-bulbar dissection technique can be used with any tumor, as long as the tumor itself has not penetrated the wall of the jugular bulb or infiltrated the cranial nerves. Tumors that hypersecrete catecholamine require perioperative management and malignant tumors carry a poor prognosis.

Abstract
BACKGROUND The juxtacondylar microsurgical approach is an adequate alternative to the classical infratemporal approach for the resection of tumors of the jugular foramen. PATIENTS AND METHODS Retrospectively, we report on our experience with eight patients suffering from tumors of the jugular foramen with different etiologies, who were treated successfully via the juxtacondylar approach with interdisciplinary cooperation. RESULTS The advantage of the juxtacondylar approach is that there is no need to expose and transpose the facial nerve. Additionally, reduction or translocation of the posterior wall of the auditory canal and removal of the ossicular chain are not necessary. CONCLUSIONS Tumors of the jugular foramen can be safely removed without damaging the facial nerve or auditory capacity, with a comparatively much better overview over the vascular and neural structures of the jugular foramen. This more neurosurgically orientated skull base approach is not very well known in the ENT surgical literature.

Abstract
The purpose of this study was to evaluate (18)F-DOPA whole-body positron emission tomography ((18)F-DOPA PET) as a biochemical imaging approach for the detection of glomus tumours. (18)F-DOPA PET and magnetic resonance imaging (MRI) were performed in ten consecutive patients with proven mutations of the succinate dehydrogenase subunit D ( SDHD) gene predisposing to the development of glomus tumours and other paragangliomas. (18)F-DOPA PET and MRI were performed according to standard protocols. Both methods were assessed under blinded conditions by two experienced specialists in nuclear medicine (PET) and diagnostic radiology (MRI). Afterwards the results were compared. A total of 15 lesions (four solitary and four multifocal tumours, the latter including 11 lesions) were detected by (18)F-DOPA PET. Under blinded conditions, (18)F-DOPA PET and MRI revealed full agreement in seven patients, partial agreement in two and complete disagreement in one. Eleven of the 15 presumed tumours diagnosed by (18)F-DOPA PET were confirmed by MRI. The correlation of (18)F-DOPA PET and MRI confirmed three further lesions previously only detected by PET. All of them were smaller than 1 cm and had the signal characteristics of lymph nodes. For one small lesion diagnosed by PET, no morphological MRI correlate could be found even retrospectively. No tumour was detected by MRI that was negative on (18)F-DOPA PET. All tumours diagnosed by MRI showed a hyperintense signal on T2-weighted images and a distinct enhancement of contrast medium on T1-weighted images. The mean tumour size was 1.5+/-0.5 cm. (18)F-DOPA PET seems to be a highly sensitive metabolic imaging procedure for the detection of glomus tumours and may have potential as a screening method for glomus tumours in patients with SDHD gene mutations.

Abstract
OBJECT Tumors of the glomus jugulare are benign, slow-growing paragangliomas. Their natural history, surgical treatment, and outcome have been well addressed in the recent literature; however, there remains a subgroup of complex tumors--multiple, giant, malignant, neuropeptide-secreting lesions, and those treated previously by an intervention with an adverse outcome--that is high risk, presents surgical challenges, and is associated with treatment controversy. In this article the authors report on a series of patients with complex glomus jugulare tumors and focus on treatment decisions, avoidance of complications, surgical refinements, and patient outcomes. METHODS In this retrospective study, the patient population was composed of 11 male and 32 female patients (mean age 47 years) with complex tumors of the glomus jugulare who were treated by the senior author within the past 20 years. These include 38 patients with giant tumors, 11 with multiple paragangliomas (seven bilateral and four ipsilateral), two with tumors that hypersecreted catecholamine, and one with a malignant tumor. Six patients had associated lesions: one dural arteriovenous malformation, one carotid artery (CA) aneurysm, two adrenal tumors, and two other cranial tumors. All but one patient presented with neurological deficits. Cranial nerve deficits, particularly those associated with the lower cranial nerves, were the prominent feature. Twenty-eight patients underwent resection in an attempt at total removal, and gross-total resection was achieved in 24 patients. Particularly challenging were cases in which the patient had undergone prior embolization or CA occlusion, after which new feeding vessels from the internal CA and vertebrobasilar artery circulation developed. The surgical technique was tailored to each patient and each tumor. It was modified to preserve facial nerve function, particularly in patients with bilateral tumors. Intrabulbar dissection was performed to increase the likelihood that the lower cranial nerves would be preserved. Each tumor was isolated to improve its resectability and prevent blood loss. No operative mortality occurred. In one patient hemiplegia developed postoperatively due to CA thrombosis, but the patient recovered after an endovascular injection of urokinase. In four patients a cerebrospinal fluid leak was treated through spinal drainage, and in five patients infection developed in the external ear canal. Two of these infections progressed to osteomyelitis of the temporal bone. There were two recurrences, one in a patient with a malignant tumor who eventually died of the disease. CONCLUSIONS Despite the challenges encountered in treating complex glomus jugulare tumors, resection is indicated and successful. Multiple tumors mandate a treatment plan that addresses the risk of bilateral cranial nerve deficits. The intrabulbar dissection technique can be used with any tumor, as long as the tumor itself has not penetrated the wall of the jugular bulb or infiltrated the cranial nerves. Tumors that hypersecrete catecholamine require perioperative management and malignant tumors carry a poor prognosis.

Abstract
The management of vagal paragangliomas is extremely challenging. Treatment of these lesions must be tailored individually for each patient. The best treatment modality depends on the patient's age and health and the size and extent of the tumor. This article discusses clinical presentation, multicentric and malignant vagal paragangliomas, evaluation, embolization, surgical management, and special considerations in the management of vagal paragangliomas.

Abstract
Paragangliomas of the head and neck are ubiquitous in their distribution, originating from the paraganglia or glomus cells within the carotid body, vagal nerve, middle ear, jugular foramen, and numerous other locations. The typical patient is middle-aged and presents late in the course of the disease, with a painless slow-growing mass. Clinical manifestations include hoarseness of voice, lower cranial nerve palsies, pulsatile tinnitus, and other neuro-otologic symptoms. The overall prognosis of patients with a cervical paraganglioma is favorable, whereas its temporal bone counterpart often results in recurrence, residual tumor, and neurovascular compromise when in the advanced stage. Pathologic examination reveals a characteristic biphenotypic cell line, composed of chief cells and sustentacular cells with a peripheral fibrovascular stromal layer that are organized into a whorled pattern ("zellballen"). Imaging hallmarks of paragangliomas of the head and neck include an enhancing soft-tissue mass in the carotid space, jugular foramen, or tympanic cavity at computed tomography; a salt-and-pepper appearance at standard spin-echo magnetic resonance imaging; and an intense blush at angiography. Imaging studies depict the location and extent of tumor involvement, help determine the surgical approach, and help predict operative morbidity and mortality. Surgical treatment is definitive. Radiation treatment is included as a palliative adjunct for the exceptional paraganglioma not amenable to surgery.

Abstract
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 multilating resections. In their place, individually tailored and combined multidirectional surgical approaches may allow total tumor removal with lower morbidity.

Abstract
Glomus tumours of the skull base are rare, but as they present with symptoms of hearing loss and tinnitus they are a clinical entity of which audiologists should be aware. This paper describes the findings of the major series of skull base glomus tumours found in the literature, and notes that the contribution of conductive and sensorineural components varies with tumour classification. The reported incidence of hearing loss and tinnitus in glomus tympanicum and glomus jugulare is reviewed and compared with the Cambridge series, in which two tumours were Fisch type A, four type B, two type C and five type D. In each case a mixed hearing loss was found, though the extent of sensorineural impairment was variable. The length of history of tumours limited to the middle-ear was far shorter (mean 8 months) than for more extensive lesions (type B, mean 64 months; C, 48 months; and D, 23 months). Eleven patients (85%) reported the symptom of hearing loss, and 12 (92.5%) of tinnitus, and some patients had experienced these symptoms for some time without seeking the advice of an otologist. It may be concluded that the presence of subjective pulsatile tinnitus or a retrotympanic mass should be considered an indication for an otological opinion, wherein the use of high resolution imaging techniques and arteriography will be considered in conjunction with detailed audiological assessment. Audiologists should be aware of the possibility of glomus tumour in such cases.

Abstract
A 42-year-old woman presented with otorrhea 22 years after extracranial resection of a norepinephrine-secreting glomus jugulare tumor with intravascular embolization and radiation therapy to the intracranial portion of the tumor. Tumor growth was arrested and was associated with a decrease in blood and urine norepinephrine levels. Extensive evaluation of the otorrhea, including computerized tomography-cisternography, gadolinium-enhanced magnetic resonance imaging, and arteriography showed marked diffuse necrosis of the temporal bone and skull base with limited tumor vascularity. Cerebrospinal fluid (CSF) collected from the right ear showed norepinephrine levels of 2975 pg/ml; plasma norepinephrine levels were normal. The precise site of CSF leakage could not be delineated. Exploration of the posterior fossa revealed a large dural defect at the anteromedial aspect of the petrous bone through which CSF flowed over the surface of the residual extradural glomus tumor. The defect was successfully sealed with a fascial patch. Postoperatively, CSF norepinephrine levels were normal and no further leakage was observed.

Abstract
Complete resection with conservation of cranial nerves is the primary goal of contemporary surgery for glomus jugulare tumors. This publication reports the value of combined surgical approaches in achieving this goal in 12 patients with extensive tumors. Eleven of these tumors were classified as Fisch Class C and/or D, while eight were categorized as Jackson-Glasscock Grade III or IV. Intracranial (intradural) extension was present in 10 patients; four patients had tumor extension into the clivus and two into the cavernous sinus. The petrous internal carotid artery (ICA) was involved in eight and the vertebral artery (VA) in one. Subtemporal-infratemporal, retrosigmoid, and/or extreme lateral transcondylar approaches were added to the usual transtemporal-infratemporal approach. This improved the exposure, provided early control of the petrous ICA, and facilitated tumor removal from the clivus, cavernous sinus, posterior fossa, and foramen magnum, allowing a single-stage resection in eight patients. Ten patients had a complete microscopic resection with no mortality. The facial nerve was preserved in nine cases, with tumor involvement requiring nerve resection followed by grafting in the remaining three. Mobilization of the facial nerve was avoided in five cases; of these, three had intact function and two had House-Brackmann Grade III function on follow-up review. Only one patient had a mild persistent swallowing difficulty. The ICA was preserved in 10 patients and resected in two, while the VA required reconstruction in one case. There were no instances of stroke, and blood transfusions were required in five patients who had tumors with nonembolizable ICA or VA feeders. While complete resection provides the best possibility for cure, the important role of adjuvant radiation therapy in cases with residual tumor is discussed. The importance of degrees of brain-stem compression and vascular encasement is emphasized in classifying the more extensive tumors.

Abstract
During the years 1984 to 1991, of 32 patients who had one large glomus or carotid body tumour, six were found to have other paragangliomas. Excluded from the above total of 32 are patients whose only lesion was a solitary glomus tympanicum. No two patients had identical problems and no pattern emerged on which patient management in any particular case could be based. The major problems associated with the tumours themselves and their treatment is the risk to hearing and the lower cranial nerves. Individual cases and their treatment are discussed.

Abstract
Two cases of paraganglioma arising from the parasellar region are presented. Both occurred in middle-aged women who sought treatment of headaches but who had no endocrinological dysfunction; one case was associated with ophthalmoplegia from cavernous sinus involvement. Diagnosis in both cases was confirmed by typical histological appearance and cytochemical demonstration of immunoreactive chromogranin in tumor cells. The pathological features and possible pathogenesis of parasellar paragangliomas are discussed.

Abstract
A 12-year-old girl presented with bilateral carotid-body paragangliomas and a unilateral jugular paraganglioma. The tumours were surgically removed. This is a rare combination of tumours in any patient and previously unreported in a child of this age. Her father died of a cerebellar astrocytoma and her mother underwent surgical removal of a large mediastinal paraganglioma. The association of astrocytoma with familial paragangliomas has never been documented. The literature on the epidemiology and inheritance pattern of familial paragangliomas is reviewed. The need for thorough pre-operative evaluation of the patient and close follow-up of family members is stressed.
