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
AIMS AND BACKGROUND The treatment of glomus jugulare tumors (GJT) remains controversial due to high morbidity. Historically, these tumors have primarily been managed surgically. The purpose of this retrospective review was to assess the tumor and clinical control rates as well as long-term toxicity of GJT treated with radiosurgery. METHODS Between 1993 and 2014, 30 patients with GJT (31 tumors) were managed with radiosurgery. Twenty-one patients were female and the median age was 59 years. Twenty-eight patients (93%) were treated with radiosurgery, typically at 14 Gy ( n = 26), and 2 patients (7%) with stereotactic radiosurgery. Sixteen cases (52%) had undergone prior surgery. RESULTS The mean follow-up was 4.6 years (range 1.5-12). Crude overall survival, tumor control, clinical control, and long-term grade 1 toxicity rates were 97%, 97%, 97%, and 13% (4/30), respectively. No statistically significant risk factor was associated with lower tumor control in our series. Univariate analysis showed a statistically significant association between patients having 1 cranial nerve (CN) involvement before radiosurgery and a higher risk of lack of improvement of symptoms (odds ratio 5.24, 95% confidence interval 1.06-25.97, p = .043). CONCLUSIONS Radiosurgery is an effective and safe treatment modality for GJT. Patients having 1 CN involvement before radiosurgery show a higher risk of lack of improvement of symptoms.

Abstract
OBJECTIVE Determine treatment outcomes of stereotactic radiosurgery (SRS) for glomus jugulare tumors (GJT), focusing on three-dimensional volume change and symptoms before and after SRS, as well as complications related to SRS. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Thirty-eight patients treated with SRS between 2000 and 2015. INTERVENTION SRS treatment of GJT. MAIN OUTCOME MEASURES The tumor volumes on pre- and posttreatment imaging were compared utilizing the Leskell GammaPlan treatment plan software to assess tumor progression. Pre- and posttreatment symptoms, Fisch classification, and complications were recorded. RESULTS The mean radiographic follow-up was 39.1 months. The mean dose-to-tumor margin was 13.2 Gy. The mean tumor size at treatment was 5.8 and 5.2 cm at last follow-up. Thirty-three patients had follow-up imaging suitable for analysis. When defining both 10 and 15% tumor size increases as significant, 27 (82%) and 29 (88%) tumors decreased in size or remained stable, respectively. For the seven tumors with documented pre-SRS growth, treatment success was 86%. The mean marginal dose for treatment success and failure were 13.2 and 13.7 Gy, respectively. Patients receiving a higher margin dose had a greater risk of tumor progression (p = 0.0277). Fisch classification did not impact tumor progression rate. Initial tumor volume had no significance on tumor response to SRS. CONCLUSIONS SRS is an effective treatment option for GJT. Both initial tumor volume and Fisch classification did not impact tumor progression. There were no significant patient or lesion characteristics that distinguished treatment success and/or failure.

Abstract
BACKGROUND Paragangliomas are highly vascular and predominantly benign neoplasms that traditionally have been treated by surgery, embolization, and/or external beam radiotherapy. The aim of this study was to evaluate long-term local tumor control and the safety of radiosurgery for head and neck paragangliomas. METHODS Data were obtained from prospectively maintained databases of patients affected by brain tumors treated with radiosurgery at our institution. The inclusion criteria were histologically proven or radiologic-suspected diagnosis of paragangliomas; a follow-up period of at least 12 months, an magnetic resonance imaging-based tumor growth control analysis and a signed written consent. Twenty patients (21 paragangliomas) met the eligibility criteria and were included in the present study. All patients were clinically and radiologically evaluated before and after treatment. RESULTS The mean follow-up at the time of the present analysis was 46 months. Seven patients had a follow-up longer than 60 months. Seven lesions underwent a single-session radiosurgery with a mean dose of 12.2 Gy (range 11-13 Gy). Fourteen lesions underwent multisession radiosurgery with a mean dose of 25.7 Gy (range 20-30 Gy) delivered in 3-5 fractions. The mean tumor volume for single-session radiosurgery was 4 cc (range 1.4-9.2). The mean volume for multisession radiosurgery was 18.9 cc (range 1.3-50.9). None of the lesions showed progression on radiology during the follow-up period. Neurologic conditions generally are maintained or improved. CONCLUSIONS Both single and multisession radiosurgery were confirmed as a safe and effective treatment modality for paragangliomas. Multisession radiosurgery appears effective to treat large lesions.

Abstract
OBJECTIVE Glomus jugulare tumors are rare indolent tumors that frequently involve the lower cranial nerves (CNs). Complete resection can be difficult and associated with lower CN injury. Gamma Knife radiosurgery (GKRS) has established its role as a noninvasive alternative treatment option for these often formidable lesions. The authors aimed to review their experience at the National Centre for Stereotactic Radiosurgery, Sheffield, United Kingdom, specifically the long-term tumor control rate and complications of GKRS for these lesions. METHODS Clinical and radiological data were retrospectively reviewed for patients treated between March 1994 and December 2010. Data were available for 75 patients harboring 76 tumors. The tumors in 3 patients were treated in 2 stages. Familial and/or hereditary history was noted in 12 patients, 2 of whom had catecholamine-secreting and/or active tumors. Gamma Knife radiosurgery was the primary treatment modality in 47 patients (63%). The median age at the time of treatment was 55 years. The median tumor volume was 7 cm3, and the median radiosurgical dose to the tumor margin was 18 Gy (range 12-25 Gy). The median duration of radiological follow-up was 51.5 months (range 12-230 months), and the median clinical follow-up was 38.5 months (range 6-223 months). RESULTS The overall tumor control rate was 93.4% with low CN morbidity. Improvement of preexisting deficits was noted in 15 patients (20%). A stationary clinical course and no progression of symptoms were noted in 48 patients (64%). Twelve patients (16%) had new symptoms or progression of their preexisting symptoms. The Kaplan-Meier actuarial tumor control rate was 92.2% at 5 years and 86.3% at 10 years. CONCLUSIONS Gamma Knife radiosurgery offers a risk-versus-benefit treatment option with very low CN morbidity and stable long-term results.

Abstract
We came across a case of jugular foramen mass causing positional hoarseness on turning the head left and disappearing on returning the head to a straight position. Hoarseness of voice due to vagus nerve involvement is seen in jugular foramen mass but positional hoarseness has never been seen before. We report this rarest presentation and discuss the pathophysiology behind it.

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
Stereotactic radiosurgery (SRS), a very highly focused form of therapeutic irradiation, has been widely recognized as a viable treatment option in the management of intracranial pathologies including benign tumors, malign tumors, vascular malformations and functional disorders. The applications of SRS are continuously expanding thanks to the ever-increasing advances and corresponding improvements in neuroimaging, radiation treatment techniques, equipment, treatment planning and delivery systems. In the context of glomus jugulare tumors (GJT), SRS is being more increasingly used both as the upfront management modality or as a complementary or salvage treatment option. As its safety and efficacy is being evident with compiling data from studies with longer follow-up durations, SRS appears to take the lead in the management of most patients with GJT. Herein, we address current concepts, recent advances and future perspectives in SRS of GJT in light of the literature.

Abstract
BACKGROUND The purpose of this study was to share our review of surgical strategies and long-term outcomes in the management of tympanojugular paragangliomas. METHODS This was a retrospective study with a literature review. The records of 184 patients with 185 tympanojugular paragangliomas were analyzed for tumor class, surgical procedure, preoperative vascular management, and perioperative sequelae. RESULTS Of class C1, C2, C3, and C4 tumors, we found 46 (24.9%), 95 (51.3%), 41 (22.2%), and 3 (1.6%), respectively. One hundred four (56.2%) tumors had intracranial extensions and 8 (4.3%) involved the vertebral artery. A single-stage procedure was adopted in 158 (85.4%) tumors. The infratemporal fossa type A approach was used in all cases. In 17 patients (9.7%), an intra-arterial stenting of the internal carotid artery was performed. Gross-total tumor removal was achieved in 166 cases (89.7%) and 4 (2.4%) among them developed a recurrence. CONCLUSION A thorough understanding of skull base techniques and a logical decision-making process in the management of tympanojugular paragangliomas can achieve a high rate of success in terms of recurrences and complications. © 2015 Wiley Periodicals, Inc.

Abstract
BACKGROUND The optimal treatment of glomus jugulare tumors (GJTs) remains controversial. Due to the critical location, microsurgery still provides high treatment-related morbidity and a decreased quality of life. Thus, we performed stereotactical radiosurgery (SRS) for the treatment of GJTs and evaluated the long-term outcome. METHODS Between 1991 and 2011, 32 patients with GJTs underwent SRS using a linear accelerator (LINAC) either as primary or salvage therapy. Twenty-seven patients (median age 59.9 years, range 28.7-79.9 years) with a follow-up greater than five years (median 11 years, range 5.3-22.1 years) were selected for retrospective analysis. The median therapeutic single dose applied to the tumor surface was 15 Gy (range 11-20 Gy) and the median tumor volume was 9.5 ml (range 2.8-51 ml). RESULTS Following LINAC-SRS, 10 of 27 patients showed a significant improvement of their previous neurological complaints, whereas 12 patients remained unchanged. Five patients died during follow-up due to old age or other, not treatment-related reasons. MR-imaging showed a partial remission in 12 and a stable disease in 15 patients. No tumor progression was observed. The actuarial overall survival rates after five, ten and 20 years were 100%, 95.2% and 79.4%, respectively. CONCLUSIONS Stereotactic LINAC-Radiosurgery can achieve an excellent long-term tumor control beside a low rate of morbidity in the treatment of GJTs. It should be considered as an alternative therapy regime to surgical resection or fractionated external beam radiation either as primary, adjuvant or salvage therapy.

Abstract
PURPOSE To analyze the results after surgery or stereotactic radiotherapy (SRT) in the treatment of cervical paragangliomas. Against this background, the decision-making algorithm used in the treatment of carotid body tumors (CBTs) and vagal paragangliomas (VPs) was reevaluated relative to the existing literature on the topic. MATERIALS AND METHODS Retrospective study between 2000 and 2012. A total of 27 CBTs and nine VPs in 32 patients were treated. Shamblin class I: 59.3% (n=16); class II: 29.6% (n=8); class III: 11.1% (n=3). Treatment modalities were surgery, radiotherapy, or observation. The end points for analysis were long-term tumor control and integrity of the cranial nerves. RESULTS 21 CBTs and seven VPs underwent surgery; SRT was performed in three CBTs and two VPs. Three CBTs were clinically observed. Permanent nerve paresis followed after surgery for CBTs in five patients (20%) and in all patients with VPs. No impaired cranial nerve function resulted after SRT. The median follow-up period was 4.7 years. The tumor control rate after therapy for CBTs and VPs was 100%. One CBT that received clinical observation showed slow tumor progression. CONCLUSIONS A surgical procedure should be regarded as the treatment of choice in patients with small CBTs. In larger CBTs, particularly in elderly patients with unimpaired cranial nerves, radical surgery should be regarded critically. As surgery for VPs caused regularly impairment of cranial nerves with functional disturbances of various degrees a comprehensive consultation with the patient is mandatory and nonsurgical strategies should be discussed.

Abstract
We evaluated the treatment results of robotic stereotactic radiosurgery (SRS) in our patients with unresectable glomus jugulare tumors (GJTs). The medical charts of fourteen patients with GJT, who were treated with robotic SRS, were retrospectively evaluated. The gross tumor volume was described as the clinical target volume. The median dose to the tumor was 25 Gy in median 5 fractions. The dose was normalized to 80% isodose line. All patients were evaluated for tumor growth and clinical outcome every 6 months in the first 2 years and then annually. Median follow-up was 39 months (range, 7–60 months). Lesions were stable in 8 patients, and tumor regression was observed in 6 patients. We did not observe any treatment related toxicity in our patients. In conclusion, according to our early experience, robotic SRS seems to be successful treatment option in the management of unresectable GJTs.

Abstract
Object
Glomus tumors are rare skull base neoplasms that frequently involve critical cerebrovascular structures and lower cranial nerves. Complete resection is often difficult and may increase cranial nerve deficits. Stereotactic radiosurgery has gained an increasing role in the management of glomus tumors. The authors of this study examine the outcomes after radiosurgery in a large, multicenter patient population.
Methods
Under the auspices of the North American Gamma Knife Consortium, 8 Gamma Knife surgery centers that treat glomus tumors combined their outcome data retrospectively. One hundred thirty-four patient procedures were included in the study (134 procedures in 132 patients, with each procedure being analyzed separately). Prior resection was performed in 51 patients, and prior fractionated external beam radiotherapy was performed in 6 patients. The patients' median age at the time of radiosurgery was 59 years. Forty percent had pulsatile tinnitus at the time of radiosurgery. The median dose to the tumor margin was 15 Gy. The median duration of follow-up was 50.5 months (range 5–220 months).
Results
Overall tumor control was achieved in 93% of patients at last follow-up; actuarial tumor control was 88% at 5 years postradiosurgery. Absence of trigeminal nerve dysfunction at the time of radiosurgery (p = 0.001) and higher number of isocenters (p = 0.005) were statistically associated with tumor progression–free tumor survival. Patients demonstrating new or progressive cranial nerve deficits were also likely to demonstrate tumor progression (p = 0.002). Pulsatile tinnitus improved in 49% of patients who reported it at presentation. New or progressive cranial nerve deficits were noted in 15% of patients; improvement in preexisting cranial nerve deficits was observed in 11% of patients. No patient died as a result of tumor progression.
Conclusions
Gamma Knife surgery was a well-tolerated management strategy that provided a high rate of long-term glomus tumor control. Symptomatic tinnitus improved in almost one-half of the patients. Overall neurological status and cranial nerve function were preserved or improved in the vast majority of patients after radiosurgery.

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
INTRODUCTION Temporal bone paragangliomas are rare, benign neuroendocrine tumors. Depend on their location at skull base, they can extend intracranially and extracranially. They characterize by slowly growth and late nonspecific clinical manifestation. Location of tumor and anatomical condition require suitable operational technique and cause related complications. AIM The aim of this study was analysis of surgical procedure and evaluation of treatment results of patients with paragangliomas of the temporal bone hospitalized in Department of Otolaryngology of Warsaw Medical University in years 2000-2010. MATERIAL AND METHODS 34 cases of patients were retrospectively studied. Clinical data, level of tumor advancement according to Glasscock & Jackson and Fisch classification were analyzed. Intraoperative and imaging studies data were used to evaluate extent of lesions. Suitable operative approaches and outcome of treatment were also analyzed. CONCLUSION In group of 34 patients 26 of them had monocentric and 8 multicentric neoplasms. Age ranged 15-73-years-old. Most common symptoms were: loss of hearing, tinnitus and headache. Preoperative embolization was carried in 10 cases. Most common surgery technique: tympanotomy and hypotympanotomy posterior and infratemporal fossa of Fisch type A approaches. Radiotherapy was used in 2 cases and surgery with radiation therapy in 7 cases. Most commonly observed complication in surgical treatment was intermittent paresis.

Abstract
Surgery for jugular paraganglioma (PGL) tumors often results in the acquisition of neurological deficits where none had been present previously. This has a significant impact on the quality of life. Radiotherapy is a recognized alternative therapy. The aim of this study was to compare the results of radiotherapy and surgery for the management of jugular PGL in terms of function and tumor control to define a treatment algorithm. We conducted a retrospective and comparative analysis of the treatment of 41 patients by conventional radiotherapy and 47 patients by surgery via tertiary referral at an academic medical center. Forty-seven patients with type C and/or D jugular PGLs (mean age, 46 years) underwent surgery after endovascular embolization between 1984 and 1998 using an infratemporal fossa type A approach. The facial nerve was transposed in 18 patients. An adjunctive neurosurgical procedure was required in 14 patients. Mean follow-up was 66 months (range, 17 months to 14 years). Forty-one patients with type C jugular PGLs (mean age, 59.5 years) were treated by external beam or conformational radiotherapy between 1988 and 2003 with a total mean dose of 45 Gy (range, 44 to 50 Gy). Mean follow-up was 50 months (range, 18 months to 13 years). The primary outcome measures were tumor control and cranial nerve status. Surgical resection, total or subtotal, yielded an overall 86% rate of either cure or tumor stabilization. Radiotherapy achieved local control in 96% of patients. For surgery, the main postoperative complications were dysphagia, aspiration, and facial paralysis. Patients treated by radiotherapy developed minor disabilities. We concluded that radiotherapy and surgery achieve similar oncologic outcomes, but the former achieves tumor control with less morbidity. Our data favor radiotherapy as treatment for jugular PGLs, but we acknowledge that the aims of these two treatment modalities are different, namely, eradication of tumor by surgery versus stabilization of tumor with radiotherapy. The search for the better quality of life has to be weighed against the uncertainty of the long-term behavior of the tumor.

Abstract
Swallowing problems following jugular foramen surgery are more common than is often acknowledged and affect up to a third of our patients. They have a significant effect on quality of life. We have become more proactive in this respect and anticipate these problems before they become established. In this article we present our management protocol that has evolved over the past 30 years as a result of our experience treating 134 glomus jugulare tumors. Our current protocol involves a thorough preoperative assessment of swallowing. After jugular foramen surgery, patients undergo further evaluation using fiberoptic endoscopic evaluation of swallowing (FEES), videofluoroscopy, and manometry. Those with prolonged or poorly compensated dysphagia are offered rehabilitation surgery. We describe this technique, which has proved beneficial to our patients. Guidelines for management are proposed.

Abstract
Object
Because of the rarity of glomus jugulare tumors, a variety of treatment paradigms are currently used. There is no consensus regarding the optimal management to control tumor burden while minimizing treatment-related morbidity. In this study, the authors assessed data collected from 869 patients with glomus jugulare tumors from the published literature to identify treatment variables that impacted clinical outcomes and tumor control rates.
Methods
A comprehensive search of the English-language literature identified 109 studies that collectively described outcomes for patients with glomus jugulare tumors. Univariate comparisons of demographic information between treatment cohorts were performed to detect differences in the sex distribution, age, and Fisch class of tumors among various treatment modalities. Meta-analyses were performed on calculated rates of recurrence and cranial neuropathy after subtotal resection (STR), gross-total resection (GTR), STR with adjuvant postoperative radiosurgery (STR+SRS), and stereotactic radiosurgery alone (SRS).
Results
The authors identified 869 patients who met their inclusion criteria. In these studies, the length of follow-up ranged from 6 to 256 months. Patients treated with STR were observed for 72 ± 7.9 months and had a tumor control rate of 69% (95% CI 57%–82%). Those who underwent GTR had a follow-up of 88 ± 5.0 months and a tumor control rate of 86% (95% CI 81%–91%). Those treated with STR+SRS were observed for 96 ± 4.4 months and had a tumor control rate of 71% (95% CI 53%–83%). Patients undergoing SRS alone had a follow-up of 71 ± 4.9 months and a tumor control rate of 95% (95% CI 92%–99%). The authors' analysis found that patients undergoing SRS had the lowest rates of recurrence of these 4 cohorts, and therefore, these patients experienced the most favorable rates of tumor control (p < 0.01). Patients who underwent GTR sustained worse rates of cranial nerve (CN) deficits with regard to CNs IX–XI than those who underwent SRS alone; however, the rates of CN XII deficits were comparable.
Conclusions
The authors' analysis is limited by the quality and accuracy of these studies and may reflect source study biases, as it is impossible to control for the quality of the data reported in the literature. Finally, due to the diverse range of data presentation, the authors found that they were limited in their ability to study and control for certain variables. Some of these limitations should be minimized with their use of meta-analysis methods, which statistically evaluate and adjust for between-study heterogeneity. These results provide the impetus to initiate a prospective study, appropriately controlling for variables that can confound the retrospective analyses that largely comprise the existing literature.

Abstract
Background Glomus jugulare is a slowly growing, locally destructive tumor located in the skull base with difficult surgical access. The operative approach is, complicated by the fact that lesions may be both intra and extradural with engulfment of critical neurovascular structures. The tumor is frequently highly vascular, thus tumor resection entails a great deal of morbidity and not infrequent mortality. At timeslarge residual tumors are left behind. To decrease the morbidity associated with surgical resection of glomus jugulare, gamma knife surgery (GKS) was performed as an alternative in 13 patients to evaluate its safety and efficacy. Methods A retrospective review of 13 residual or unresectable glomus jagulare treated with GKS between 2004 and 2008.. Of these, 11 patients underwent GKS as the primary management and one case each was treated for postoperative residual disease and postembolization. The radiosurgical dose to the tumor margin ranged between 12-15 Gy. Results Post- gamma knife surgery and during the follow-up period twelve patients demonstrated neurological stability while clinical improvement was achieved in 5 patients. One case developed transient partial 7th nerve palsy that responded to medical treatment. In all patients radiographic MRI follow-up was obtained, the tumor size decreased in two cases and remained stable (local tumor control) in eleven patients. Conclusions Gamma knife surgery provids tumor control with a lowering of risk of developing a new cranial nerve injury in early follow-up period. This procedure can be safely used as a primary management tool in patients with glomus jugulare tumors, or in patients with recurrent tumors in this location. If long-term results with GKS are equally effective it will emerge as a good alternative to surgical resection.

Abstract
Paragangliomas are highly vascular and predominantly benign neoplasms that have traditionally been treated by surgery, embolization and/or external beam radiotherapy (EBRT). The aim of this study is to evaluate the short-term local tumor control and safety of CyberKnife radiosurgery for these lesions. Nine patients, eight with jugular glomus paragangliomas and one with a carotid body paraganglioma, were treated. The target contouring was performed on merged CT and MR images. Eight patients were treated with doses ranging from 11 to 13 Gy (mean 12.5 Gy) in a single fraction and one with 24 Gy in three fractions prescribed to 72-83% isodose line. The mean follow-up was 20 months. One patient died from unrelated causes. There were no local recurrences. All eight patients also demonstrated neurological stability or improvement. Neither cranial nerve palsies have arisen, nor has deterioration beyond baseline been observed. In conclusion, CyberKnife radiosurgery appears to be both safe and effective in the treatment of skull base paragangliomas. Determining whether long-term complications will arise will require further investigation.

Abstract
INTRODUCTION Glomus jugulare tumours represent a great therapeutic challenge. Previous papers have documented good results from Gamma Knife surgery (GKS) with these tumours. However, the relationship between clinical improvement and tumour shrinkage has never been assessed. MATERIALS AND METHODS There were 14 patients, 9 women and 5 men. The mean follow-up period was 28 months (range 6 to 60 months). All the tumours except one were Fisch type D and the mean volume was 14.2 cm(3) (range 3.7-28.4 cm(3)). The mean prescription dose was 13.6 Gy (range 12-16 Gy). RESULTS None of the tumours have continued to grow. Eight are smaller and 6 unchanged in volume. Two patients with bruit have had no improvement in their symptoms. Among the other 12 patients, 5 have had symptomatic improvement of dysphagia, 4 in dysphonia, 3 in facial numbness, 3 in ataxia and 2 in tinnitus. Individual patients have experienced improvement in vomiting, vertigo, tongue fasciculation, hearing, headache, facial palsy and accessory paresis. One patient developed a transient facial palsy. Symptomatic improvement commonly began before any reduction in tumour volume could be detected. The mean time to clinical improvement was 6.5 months whereas the mean time to shrinkage was 13.5 months. CONCLUSIONS Gamma Knife treatment of glomus jugulare tumours is associated with a high incidence of clinical improvement with few complications, using the dosimetry recorded here. Clinical improvement would seem to be a more sensitive early indicator of therapeutic success than radiological volume reduction. Further follow-up will be needed.

Abstract
OBJECTIVES Jugular foramen paraganglioma is a locally invasive, benign tumor, which grow slowly and causes various symptoms such as pulsatile tinnitus and low cranial nerve palsy. Complete surgical resection is regarded as the ideal management of these tumors. The goal of this study is to identify the clinical characteristics and most effective surgical approach for jugular foramen paraganglioma. METHODS Retrospective analysis of 9 jugular foramen paraganglioma patients who underwent surgical resection between 1986 and 2005 was performed. Clinical records were reviewed for analysis of initial clinical symptoms and signs, audiological examinations, neurological deficits, radiological features, surgical approaches, extent of resection, treatment outcomes and complications. RESULTS Most common initial symptom was hoarseness, followed by pulsatile tinnitus. Seven out of 9 patients had at least one low cranial nerve palsy. Seven patients were classified as Fisch Type C tumor and remaining 2 as Fisch Type D tumor on radiologic examination. Total of 11 operations took place in 9 patients. Total resection was achieved in 6 cases, when partial resection was done in 3 cases. Two patients with partial resection received gamma knife radiosurgery (GKS), when remaining 1 case received both GKS and two times of revision operation. No mortality was encountered and there were few postoperative complications. CONCLUSION Neurologic examination of low cranial nerve palsy is crucial since most patients had at least one low cranial nerve palsy. All tumors were detected in advanced stage due to slow growing nature and lack of symptom. Angiography with embolization is crucial for successful tumor removal without massive bleeding. Infratemporal fossa approach can be considered as a safe, satisfactory approach for removal of jugular foramen paragangliomas. In tumors with intracranial extension, combined approach is recommended in that it provides better surgical view and can maintain the compliance of the patients.

Abstract
What is believed to be the first case of a glomus jugulare tumor presenting with intracerebellar hemorrhage is described. A 25-year-old normotensive man suddenly suffered from severe headache, nausea, vomiting, vertigo, and ataxia due to an intracerebellar hemorrhage. Magnetic resonance imaging and angiography revealed a highly vascular jugulare foramen tumor extending into the intracranial space adjacent to the hematoma. Total removal of the tumor was performed successfully via the combined pre- and retrosigmoid approach, and the histologic diagnosis was a glomus jugulare tumor. We concluded that one of the numerous draining veins on the surface of intracranial tumor, which were observed during the operation, was the origin of the intracerebellar hemorrhage.

Abstract
ObjectGlomus jugulare tumors (GJT) have traditionally been treated by surgery or fractionated external-beam radiotherapy. The aim of this retrospective study was to determine the tumor control rate, clinical outcome, and short-term complications of stereotactic radiosurgery in subsets of patients who are poor candidates for these procedures, based on age, medical problems, tumor size, or prior treatment failure.MethodsThe Leksell Gamma Knife was used to treat 16 patients harboring symptomatic, residual, recurrent, or unresectable GJTs. The age of the patients ranged from 12 to 77 years (median 46.5 years). Gamma Knife surgery (GKS) was performed as primary treatment in five patients (31.3%). Microsurgery preceded radiosurgery in 10 patients (62.5%) and fractionated radiotherapy in three patients (18.8%). The median tumor volume was 9.8 cm3 (range 1.7–20.6 cm3). The median marginal dose applied to a mean isodose volume of 50% (range 37–70%) was 18 Gy (range 14–20 Gy).Neurological follow-up examinations revealed improved clinical status in 10 patients (62.5%), a stable neurological status in six (37.5%), and no complications. After radiosurgery, follow-up imaging was conducted in 14 patients; the median interval from GKS to the last follow up was 18.5 months (range 4–28 months). Tumor size had decreased in six patients (42.9%), and the volume remained unchanged in the remaining eight (57.1%). None of the tumors increased in volume during the observation period.Conclusions According to the authors' experience, GKS represents a useful therapeutic option to control symptoms and may be safely conducted in patients with primary or recurrent GJTs with no death and no acute morbidity. Because of the tumor's naturally slow growth rate, however, long-term follow-up data are needed to establish a cure rate after radiosurgery.

Abstract
Abstract
OBJECTIVE:
Glomus jugulare tumors are generally considered slow-growing, benign lesions. However, their pronounced local aggressiveness frequently results in severe neurological deficits. Surgical removal is rarely radical and is usually associated with morbidity. There is increasing evidence that stereotactic radiosurgery, particularly gamma knife radiosurgery (GKR), may play a relevant role as a therapeutic option in these tumors.
METHODS:
Between 1996 and 2005, we used GKR to treat 20 patients bearing growing glomus jugulare tumors, mostly classified as Glasscock-Jackson Grade IV or Fisch Stage D1. Follow-up (mean, 50.85 mo) data was available for 20 patients (four men, 16 women; mean age, 56 yr): eight out of 20 tumors were surgical recurrences, three out of 20 patients had GKR as the primary treatment, and 11 out of 20 patients previously underwent endovascular embolization. Regarding the radiosurgical dose planning, the average tumor volume was 7.03 cm3 (range, 1.5–13.4 cm3) and the mean marginal dose was 17.3 Gy (range, 13–24 Gy).
RESULTS:
Neurological signs and symptoms were unchanged in 13 out of 20 patients. An improvement of cranial nerve function was observed in five patients and hearing deterioration was observed in two patients. Tumor volume was unchanged in 11 out of 20 patients and was slightly (≤ 20%) decreased in eight out of 20 patients. In one unusual case of a bulky cavernous sinus recurrence, neoplastic regression was particularly pronounced.
CONCLUSION:
Despite the constraints of the limited case material, considering the estimated doubling time of these rare tumors (4.2 yr), our preliminary results with GKR at a mid-term follow-up examination suggest an effective tumor growth control with negligible incidence of untoward sequelae.

Abstract
A 44-year-old woman presented with a history of increasing left hypoacusis and sporadic vertigo. CT scan revealed a tumor occupying the mastoid, middle ear, and external auditory canal. After surgical removal, a typical secretory meningioma was diagnosed. The histological hallmark and the immunohistochemical profile of secretory meningiomas are reviewed. The differential diagnosis of this tumor in this location is also commented on. As far as we know, primary temporal bone meningiomas with secretory histology have not been previously reported in the medical literature.

Abstract
PURPOSE The management of paragangliomas is controversial. Observation, surgery, external-beam radiotherapy (EBRT), and stereotactic radiosurgery (SRS) may, alone or in combination, be appropriate, depending on the size and extent of the tumor, previous treatment, and patient age, general health, and neurologic condition. Few data exist regarding long-term tumor control and late effects after EBRT or SRS. METHODS AND MATERIALS We performed a retrospective review of all patients treated with EBRT or SRS for paraganglioma at our institution between 1967 and 1994. The endpoints of the study were tumor control and late complications. RESULTS The 33 patients in this study had a median follow-up of 13 years (range, 4 months to 36 years). The 10-year tumor control rate was 92% (95% confidence interval, 75-98%). At the last follow-up visit, no patient had developed a radiation-induced malignancy. CONCLUSION External-beam RT and SRS are safe and effective for enlarging and/or symptomatic paragangliomas. The risk of developing a delayed radiation-induced malignancy after EBRT or SRS is low. This risk must be weighed against the significant immediate and permanent risk of cranial nerve deficits if the tumor is untreated or is surgically resected. This risk must also be weighed against the immediate but low risk of surgical mortality.

Abstract
Microsurgical resection remains the mainstay of treatment for truly benign brain tumors that can be safely resected because of the potential for permanent cure with most histologic findings, including most of the histologic findings discussed in this article. Physicians must keep in mind the indolent nature of many of the benign brain tumors and realize that many patients are likely to live out normal life spans if tumor control is achieved. Therefore, it is not sufficient simply to consider local tumor control rates and short-term toxicity risks when choosing between surgery, stereotactic radiosurgery, and fractionated radiotherapy. Patients need to be apprised of all therapeutic options and to make their decisions with all information required to evaluate the risks and benefits. For benign brain tumors, these decisions may have consequences that last for decades.

Abstract
OBJECTIVE The surgical removal of a jugular foramen (JF) tumor presents the neurosurgeon with a complex management problem that requires an understanding of the natural history, diagnosis, surgical approaches, and postoperative complications. Cerebrospinal fluid (CSF) leakage is one of the most common complications of this surgery. Different surgical approaches and management concepts to avoid this complication have been described, mainly in the ear, nose, and throat literature. The purpose of this study was to review the results of CSF leakage prevention in a series of 66 patients with JF tumors operated on by a multidisciplinary cranial base team using a new technique for cranial base reconstruction. METHODS We retrospectively studied 66 patients who had JF tumors with intracranial extension and who underwent surgical treatment in our institutions from January 1987 to December 2001. Paragangliomas were the most frequent lesions, followed by schwannomas and meningiomas. All patients were operated on using the same multidisciplinary surgical approach (neurosurgeons and ear, nose, and throat surgeons). A surgical strategy for reconstruction of the cranial base using vascularized flaps was carried out. The closure of the surgical wound was performed in three layers. A specially developed myofascial flap (temporalis fascia, cervical fascia, and sternocleidomastoid muscle) associated to the inferior rotation of the posterior portion of the temporalis muscle was used to reconstruct the cranial base with vascularized flaps. RESULTS In this series of 66 patients, postoperative CSF leakage developed in three cases. These patients presented with very large or recurrent tumors, and the postoperative CSF fistulae were surgically closed. The cosmetic result obtained with this reconstruction was classified as excellent or good in all patients. CONCLUSION Our results compare favorably with those reported in the literature. The surgical strategy used for cranial base reconstruction presented in this article has several advantages over the current surgical techniques used in cases of JF tumors.

Abstract
OBJECT Glomus jugulare tumors are rare tumors that commonly involve the middle ear, temporal bone, and lower cranial nerves. Resection, embolization, and radiation therapy have been the mainstays of treatment. Despite these therapies, tumor control can be difficult to achieve particularly without undo risk of patient morbidity or mortality. The authors examine the safety and efficacy of gamma knife surgery (GKS) for glomus jugulare tumors. METHODS A retrospective review was undertaken of the results obtained in eight patients who underwent GKS for recurrent, residual, or unresectable glomus jugulare tumors. The median radiosurgical dose to the tumor margin was 15 Gy (range 12-18 Gy). The median clinical follow-up period was 28 months, and the median period for radiological follow up was 32 months. All eight patients demonstrated neurological stability or improvement. No cranial nerve palsies arose or deteriorated after GKS. In the seven patients in whom radiographic follow up was obtained, the tumor size decreased in four and remained stable in three. CONCLUSIONS Gamma knife surgery would seem to afford effective local tumor control and preserves neurological function in patients with glomus jugulare tumors. If long-term results with GKS are equally efficacious, the role of stereotactic radiosurgery will expand.

Abstract
OBJECT The optimal management of glomus jugulare tumors remains controversial. Available treatments were once associated with poor outcomes and significant complication rates. Advances in skull base surgery and the delivery of radiation therapy by stereotactic radiosurgery have improved the results obtained using these treatment options. The authors summarize and compare the contemporary outcomes and complications for these therapies. METHODS Papers published between 1994 and 2004 that detailed the use of radiosurgery or surgery to treat glomus jugulare tumors were reviewed. Eight radiosurgery series including 142 patients and seven surgical studies including 374 patients were evaluated for neurological outcome, change in tumor size (radiosurgery) or percent of total resection (surgery), recurrences, tumor control, need for further treatment, and complications. The mean age at treatment for patients who underwent surgery and radiosurgery was 47.3 and 56.7 years, respectively. The mean follow-up duration was 49.2 and 39.4 months, respectively. The surgical control rate was 92.1%, with 88.2% of tumors totally resected in the initial surgery. A cerebrospinal fluid leak occurred in 8.3% of patients who underwent surgery and recurrences were found in 3.1%; the mortality rate was 1.3%. Among patients who underwent radiosurgery, tumors diminished in 36.5%, whereas 61.3% had no change in tumor size, and subjective or objective improvements occurred in 39%. Despite the presence of residual tumor in 100% of radiosurgically treated patients, recurrences were found in only 2.1%, the morbidity rate was 8.5%, and there were no deaths. CONCLUSIONS Death and recurrences after these treatments are infrequent, and therefore both treatments are considered to be safe and efficacious. Although surgery is associated with higher morbidity rates, it immediately and totally eliminates the tumor. The radiosurgery results are very promising, although the incidence of late recurrence (after 10-20 years) is unknown.

Abstract
ObjectJugular foramen tumors are rare skull base lesions that present diagnostic and complex management problems. The purpose of this study was to evaluate a series of patients with jugular foramen tumors who were surgically treated in the past 16 years, and to analyze the surgical technique, complications, and outcomes.MethodsThe authors retrospectively studied 102 patients with jugular foramen tumors treated between January 1987 and May 2004. All patients underwent surgery with a multidisciplinary method combining neurosurgical and ear, nose, and throat techniques. Preoperative embolization was performed for paragangliomas and other highly vascularized lesions. To avoid postoperative cerebrospinal fluid (CSF) leakage and to improve cosmetic results, the surgical defect was reconstructed with specially developed vascularized flaps (temporalis fascia, cervical fascia, sternocleidomastoid muscle, and temporalis muscle). A saphenous graft bypass was used in two patients with tumor infiltrating the internal carotid artery (ICA). Facial nerve reconstruction was performed with grafts of the great auricular nerve or with 12th/seventh cranial nerve anastomosis. Residual malignant and invasive tumors were irradiated after partial removal.The most common tumor was paraganglioma (58 cases), followed by schwannomas (17 cases) and meningiomas (10 cases). Complete excision was possible in 45 patients (77.5%) with paragangliomas and in all patients with schwannomas. The most frequent and also the most dangerous surgical complication was lower cranial nerve deficit. This deficit occurred in 10 patients (10%), but it was transient in four cases. Postoperative facial and cochlear nerve paralysis occurred in eight patients (8%); spontaneous recovery occurred in three of them. In the remaining five patients the facial nerve was reconstructed using great auricular nerve grafts (three cases), sural nerve graft (one case), and hypoglossal/facial nerve anastomosis (one case). Four patients (4%) experienced postoperative CSF leakage, and four (4.2%) died after surgery. Two of them died of aspiration pneumonia complicated with septicemia. Of the remaining two, one died of pulmonary embolism and the other of cerebral hypoxia caused by a large cervical hematoma that led to tracheal deviation.ConclusionsParagangliomas are the most common tumors of the jugular foramen region. Surgical management of jugular foramen tumors is complex and difficult. Radical removal of benign jugular foramen tumors is the treatment of choice, may be curative, and is achieved with low mortality and morbidity rates. Larger lesions can be radically excised in one surgical procedure by using a multidisciplinary approach. Reconstruction of the skull base with vascularized myofascial flaps reduces postoperative CSF leaks. Postoperative lower cranial nerves deficits are the most dangerous complication.

Abstract
PURPOSE To evaluate the role of fractionated stereotactic conformal radiotherapy (FSRT) as a noninvasive method in the management of large chemodectomas of the skull base. METHODS AND MATERIALS Twenty-two patients with chemodectomas of the skull base were treated with FSRT at our institution. Ten patients received primary RT, and 12 patients were treated for recurrent or progressive disease after primary surgery (8 patients) or embolization (4 patients). The median total dose was 57.6 Gy, with a median of 1.8 Gy/fraction. The median target volume was 71.8 cm3 (range, 10.5-212.2 cm3). The most common symptoms at the initial diagnosis were pulsatile tinnitus (16 patients), hearing loss (14 patients), and balance disturbance (14 patients). Twelve patients had additional cranial nerve deficits. RESULTS The median follow-up was 5.7 years (range, 19-177 months). The actuarial overall survival rate was 89.5% at 5 and 10 years. The actuarial local control rate was 90.4% at 5 and 10 years. Seven patients (32%) had a partial response and 13 (59%) had stable disease of the irradiated chemodectoma. Two symptomatic patients developed recurrence after 19 and 32 months. Neurologic dysfunction improved or completely resolved in 59% and stabilized in 32%; 9% of patients experienced impairment of preexisting neurologic dysfunction. No patient developed new neurologic deficits after FSRT. RT was interrupted in 1 patient because of a maxillary bone abscess. In all other patients, no acute or late adverse reactions greater than Common Toxicity Criteria Grade 2 were seen. CONCLUSION Fractionated stereotactic conformal radiotherapy is an effective and well-tolerated noninvasive treatment for chemodectomas, with excellent tumor control rates and a low risk of morbidity. It is an option for patients at greater risk of microsurgical resection or with residual and recurrent tumors.

Abstract
Giant glomus tumors pose a challenge to the Otologist by virtue of their location and vascularity. A vast majority of them present with tinnitus, conductive hearing loss and cranial nerve palsies. We report the case of a 16-year-old male patient who presented with sudden right-sided sensorineural hearing loss. This is an unusual presentation of a giant glomus tumor. We present the clinical features and management of this unusual case.

Abstract
BACKGROUND Glomus jugular tumours are usually managed by microsurgical resection and/or radiotherapy with considerable risk for treatment-related morbidity. The role of Gamma Knife Radiosurgery (GKRS) in the management of these lesions remains to be defined. METHOD Between May 1992 and November 2000, 19 patients with glomus tumours underwent GKRS at our department. Nine patients received radiosurgery for residual or recurrent paragangliomas following microsurgical resection and in 10 cases GKRS was performed as primary treatment. The median tumour volume was 5.22 ccm (range: 0.38-33.5 ccm). Marginal doses of 12-20 Gy (median 14 Gy) were applied to enveloping isodose volume curves (Range: 30-55%, median 50%). FINDINGS Except for an 81-year-old patient who died 9 months after radiosurgery the observation time ranged from 1.5 to 10 years (median 7.2 yrs). The total tumour control rate was 94.7% (7 cases with decreased and 11 with stable tumour size). The only patient with tumour progression (5.3%) underwent repeated radiosurgical treatment 85 months after initial GKRS. A newly diagnosed second lesion in the cavernous sinus was treated radiosurgically as well 53 months after the first Gamma Knife procedure. On clinical examination 10 patients (52.6%) presented with improved and 8 patients (42.1%) with unchanged neurological status. Deterioration in one patient (5.3%) was not related to tumour or radiosurgery. INTERPRETATION As GKRS demonstrated to be a minimally invasive treatment alternative to microsurgery and radiotherapy with no acute or chronic toxicity it should be considered more frequently in the primary or adjuvant strategy for glomus jugular tumours.

Abstract
BACKGROUND The optimal treatment for patients with glomus jugulare tumor (GJT) of the skull base remains controversial. Surgical excision is associated with a high incidence of cranial nerve injury, decreased quality of life, and high mortality. Fractionated radiotherapy is used to control the majority of these tumors, but disadvantages are a prolonged therapy interval and exposition of adjacent brain tissue to irradiation. The authors present the results of a study on 12 of 14 consecutively admitted patients who were treated using linear accelerator-based radiosurgery (LINAC-RS), an innovative method for the treatment of GJT. METHODS From May 1991 to March 2001, 14 patients with GJT were treated with stereotactic LINAC-RS for continued growth of tumor or of remaining tumor after surgery. Twelve patients (9 women and 3 men; age range, 28-71 years; median age, 59 years) with a median follow-up of 4 years (range, 0.8-9,0 years), were selected for retrospective analysis. A median single dose of 15 grays (Gy; range, 11-20 Gy) was applied to the surface of the tumor. RESULTS After undergoing LINAC-RS, 8 of 12 patients (67%) reported partial or complete subjective improvement, whereas complaints remained unchanged in 4 patients (33%). Neurologic status improved in 3 patients (25%) and remained unchanged in 8 patients (67%). Magnetic resonance images showed tumor shrinkage in 8 patients (67%) and no further progression in 4 patients (33%). CONCLUSIONS LINAC-RS is an effective and safe therapy for patients with GJT and may be used as an alternative to surgical resection. Compared with fractionated radiotherapy, LINAC-RS has some advantages. However, to clarify the question of long-term tumor control, longer observation times are required.

Abstract
BACKGROUND We evaluated toxicity and long-term efficacy of stereotactic radiosurgery in patients with symptomatic or progressive glomus jugulare tumors. METHODS Twenty-five consecutive patients (age, 30-88 years; 17 women, 8 men) who underwent stereotactic radiosurgery with the Leksell Gamma Knife (dose, 12-18 Gy) were prospectively followed. MRI and clinical examinations were performed at 6 months and 1, 2, and 3 years, and then every 2 years. RESULTS None of the tumors increased in size, 17 were stable, and 8 decreased (median imaging follow-up, 35 months; range, 10-113 months). Symptoms subsided in 15 patients (60%); vertigo occurred in 1, but balance improved with vestibular training (median clinical follow-up, 37 months; range, 11-118 months). No other new or progressive neuropathy of cranial nerves V-XII developed. CONCLUSIONS Stereotactic radiosurgery can achieve excellent tumor control with low risk of morbidity in the treatment of glomus jugulare tumors. The lower cranial nerves can safely tolerate a radiosurgical dose of 12 to 18 Gy.

Abstract
OBJECTIVES/HYPOTHESIS Surgery is considered to be the mainstay of treatment for glomus jugulare tumors. A subset of patients are poor surgical candidates based on age, medical problems, tumor size, or prior treatment failure. The purpose of this study was to review our results with stereotactic radiosurgery (gamma knife treatment) in this group of patients, with particular attention to adverse reactions and symptom relief. STUDY DESIGN Retrospective review and phone survey. METHODS Charts were reviewed for size and location of tumor, history of previous treatment, symptoms before and after treatment, amount of radiation received, acute and late complications, and functional level before and after treatment. Pre-treatment and posttreatment magnetic resonance imaging scans were also reviewed. Identified patients were then contacted for a phone interview. RESULTS Eight patients were identified. Phone interviews were conducted with four patients. Four patients had failed previous treatment. Follow-up ranged from 7 to 104 months. One patient experienced an acute complication: intractable vertigo requiring hospitalization. No patient experienced delayed cranial neuropathies. No patient reported worsening of any of the following symptoms: pulsatile tinnitus, hearing loss, facial weakness, hoarseness, or difficulty swallowing. Three patients reported improvement in their pulsatile tinnitus. Two patients reported improvement in hearing loss, and one patient each reported improvement in vertigo and difficulty swallowing. CONCLUSIONS Preliminary results suggest that stereotactic radiosurgery is useful to control symptoms and may be delivered safely in patients with primary or recurrent glomus jugulare tumors who are poor surgical candidates.

Abstract
PURPOSE This study was conducted to evaluate the toxicity and efficacy of stereotactic radiosurgery treatment of glomus jugulare tumors. METHODS AND MATERIALS Between March 1990 and January 1995, nine patients underwent stereotactic radiosurgery with the Leksell Gamma Knife Unit for glomus jugulare tumors. Previous treatment had failed in four patients. The seven female and two male patients had a median age of 67 years. RESULTS The median time from stereotactic radiosurgery to the most recent clinical follow-up was 20 months (range 7-65 months). Subjectively, 7 of 9 patients noted a decrease in the intensity of their symptoms. Objectively, 8 of 9 tumors remained stable in size by serial magnetic resonance imaging scans and one was smaller. There was no acute or chronic toxicity. CONCLUSION This early experience suggests that stereotactic radiosurgery is a promising treatment for glomus jugulare tumors.
