Abstract
BACKGROUND Transcanal endoscopic ear surgery (TEES) has become popular in recent years in the treatment of glomus tympanicum tumors (GTT). The most significant risk for TEES is bleeding. In some cases, preoperative vascular embolization is performed to mitigate bleeding during TEES. However, guidelines regarding the necessity and efficacy of preoperative vascular embolization have not been established yet. CASE PRESENTATION This report aimed to assess the necessity and usefulness of preoperative vascular embolization in TEES for GTT by comparing the surgical findings of TEES without preoperative vascular embolization (Case 1) and TEES with preoperative vascular embolization (Case 2). Compared to Case 1, Case 2 included less bleeding and a more convenient procedure. However, no significant difference was observed. CONCLUSIONS For GTT confined to the middle ear cavity (Glasscock-Jackson Grade II or less), when performed by a proficient otolaryngologist, TEES alone is sufficient without preoperative vascular embolization.

Abstract
OBJECTIVE To evaluate the clinical and audiological outcomes of transcanal endoscopic resection of middle ear paragangliomas. STUDY DESIGN Retrospective multicenter study. SETTING Tertiary referral center and private otology clinic. PATIENTS Patients who underwent transcanal endoscopic surgery between January 2015 and September 2020. INTERVENTIONS Transcanal endocope-assisted resection of middle ear paragangliomas. MAIN OUTCOME MEASURES Demographic data. RESULTS Twenty-three patients (2 men, 21 women) with a mean (standard deviation [SD]) age of 50.5 (11.8) years and stage 1 or 2 disease were included in the study. The mean follow-up time was 2.7 years (range, 1-5 yr). Preoperatively, the mean (SD) air-conduction threshold was 33.8 (17.9) dB, and the mean (SD) air-bone gap was 13.1 (13.9) dB. Postoperatively, the mean (SD) air-conduction threshold was 25.7 (10.2) dB, the mean (SD) air-bone gap was 6.3 (6.1) dB. The mean (SD) hospital stay was 27.7 (9.9) hours. No tumor regrowth was detected on magnetic resonance imaging during postoperative follow-up. CONCLUSIONS Endoscopic transcanal tumor resection is effective and feasible in the treatment of stage 1 and 2 tumors and is associated with short operative time, low risk of perioperative and postoperative complications, and rapid discharge.

Abstract
PURPOSE Brain tumours have an incidence of 1.15 to 5.14 cases per 100,000 children and are associated with significant morbidity and mortality. Radiosurgery has become a promising approach to manage these paediatric CNS tumours. The aim of the present study was to analyse the efficacy of radiosurgery in the treatment of a variety of paediatric tumours of CNS. METHODS This retrospective study was conducted from 1997 to 2012 at a single Neurosurgery centre. All paediatric patients (≤ 18 years of age) with CNS tumours who were treated with gamma knife radiosurgery (GKRS) and had a minimum follow up of 6 months were included in the study. Patients with lesions other than tumours were excluded. Clinical, radiological and GKRS planning data was collected and analysed in all patients. RESULTS A total of 76 children with brain tumours had GKRS during the study period. Of these, 40 children (with 61 neoplasms) had follow-up available and were included in the study. The mean age was 16 years (6-18 years). Seventeen patients received primary GKRS, 20 patients received secondary, and 3 patients received both. The median tumour volume was 3.3 cm3 (0.14-38.9 cm3). The mean dose was 12.56 Gy at 50% isodose line. The majority of the tumours were meningioma (n = 20) followed by acoustic schwannoma (n = 17). The mean treatment time was 67.04 min. Thirty-three tumours responded favourably to GKRS, 24 showed a stable size, 3 had no response while 1 progressed, requiring surgery. CONCLUSION GKRS has the potential to become an indispensable tool in the management of paediatric brain neoplasms.

Abstract
Jugular foramen paragangliomas (JFP) are benign tumors of neural crest origin that are located along the temporal bone in the region of the jugular bulb and middle ear. The optimal management of these lesions includes surgical excision with or without preoperative embolization as well as stereotactic radiotherapy. The use of preoperative embolization in the treatment of JFP has shown great promise to bridge patients to surgery by diminishing complication rates and decreasing intraoperative bleeding. We present three successful polyvinyl alcohol (PVA) particle embolizations of patients presenting with symptomatic JFPs. All patients recovered completely in the short term with no bleeding during or after resection of paragangliomas and they were discharged free of their presenting symptoms. Early clinical and imaging diagnosis followed by adequate treatment including preoperative transcatheter particle embolization and surgical or radiosurgical interventions can lead to excellent outcomes.

Abstract
Head and neck paragangliomas (HNPs) are rare, usually benign hyper vascularized neuroendocrine tumors that traditionally have been treated by surgery, with or without endovascular embolization, or, more recently stereotactic radiosurgery (SRS). The aim of our study is to determine the clinical and radiographic effectiveness of SRS for treatment of HNPs. A systematic search of electronic databases was performed, and 37 articles reporting 11,174 patients (1144 tumors) with glomus jugulare (GJT: 993, 86.9%), glomus tympanicum (GTT: 94, 8.2%), carotid body tumors (CBTs: 28, 2.4%), and glomus vagale (GVT: 16, 1.4%) treated with SRS definitively or adjuvantly were included. The local control (LC) was estimated from the pooled analysis of the series, and its association with SRS technique as well as demographic and clinical factors was analyzed. The median age was 56 years (44-69 years). With a median clinical and radiological follow-up of 44 months (9-161 months), LC was 94.2%. Majority of the patients (61.0%) underwent Gamma Knife Radiosurgery (GKS), but there was no statistically significant difference in LC depending upon the SRS technique (p = 0.9). Spearmen's correlation showed that LC was strongly and negatively correlated with multiple parameters, which included female gender (r = - 0.4, p = 0.001), right-sided tumor (r = - 0.3, p = 0.03), primary SRS (r = - 0.5, p ≤ 0.001), and initial clinical presentation of hearing loss (r = - 0.4, p = 0.001). To achieve a LC ≥ 90%, a median marginal dose (Gy) of 15 (range, 12-30 Gy) was required. The results corroborate that SRS in HNPs is associated with good clinical and radiological outcome.

Abstract
BACKGROUND Glomus jugulare tumors (GJTs) are uncommon and locally disruptive tumors that usually arise within the jugular foramen of the temporal bone. Surgery was the treatment of choice up until recently. In the last decades, however, radiosurgery has surfaced as a promising alternative treatment by providing excellent tumor control with low risk of cranial nerve injuries. Our aim was to examine the results of radiosurgery specifically, linear accelerator stereotactic radiosurgery (LINAC SRS) for GJT treatment. We hypothesized that radiosurgery will reduce the size of the tumor and improve neurological symptoms. DESIGN AND METHOD Between January 1, 1994 and December 31, 2013, 30 patients with GJTs were treated in Sheba Medical Center using LINAC SRS treatment. Comprehensive clinical follow-up was available for 23 patients. Sixteen patients were female and seven males with a median age of 64 years, with a range of 18-87 years. In 19 of the patients, LINAC SRS was the primary treatment, whereas in the remaining four cases, surgery or embolization preceded radiosurgery. The median treated dose to tumor margin was 14 Gy (range 12-27 Gy), and the median tumor volume before treatment was 5 ml (range 0.5-15 ml). RESULTS Following the LINAC SRS treatment, 14 of 23 patients (60%) showed improvement of previous neurological deficits, nine patients (40%) remained unchanged. At the end of a follow-up, tumor reduction was seen in 13 patients and a stable volume in eight (91% tumor control rate). Two cases of tumor progression were noted. Three patients (13%) had post- SRS complications during the follow-up, two of which achieved tumor control, while in one the tumor advanced. CONCLUSIONS LINAC SRS is a practical treatment option for GJTs, with a high rate of tumor control and satisfactory neurological improvement.

Abstract
BACKGROUND Glomus tumors are rare and benign hypervascular tumors. Surgery represented the mainstay of their treatment, even if it has been associated with high morbidity and mortality rates. Recently, the treatment shifted to a multimodal approach and Gamma Knife radiosurgery represents one of the treatment options. METHODS Authors retrospectively analyzed the clinical and radiological outcome of a series of patients who underwent Gamma Knife radiosurgery for glomus tumors. RESULTS Thirty patients underwent Gamma Knife radiosurgery. Mean tumor volume was 7.69 cc (range 0.36-24.6). Mean tumor margin dose was 16 Gy (range 13-18). Median follow-up was of 91 months (mean 90; range 11-172). Overall clinical control rate was 100%; overall volumetric tumor control rate was 96.6%. Patients' and tumors' characteristics, treatment data, and outcome have been analyzed. CONCLUSION Gamma Knife radiosurgery represents a safe and effective treatment for glomus tumors. Longer follow-up and larger cohort studies are needed to definitively outline the role of Gamma Knife radiosurgery for glomus tumors.

Abstract
BACKGROUND Glomus jugulare tumors (GJTs) are rare benign tumors, which pose significant treatment challenges due to proximity to critical structures. OBJECTIVE To evaluate the long-term clinical and radiological outcome in patients undergoing stereotactic radiosurgery (SRS) for GJTs through retrospective study. METHODS Forty-two patients with 43 GJTs were treated using Gamma Knife radiosurgery (GKRS; Elekta AB, Stockholm, Sweden) at our institute from 1997 to 2016. Clinical, imaging, and radiosurgery data were collected from an institutional review board approved database. RESULTS Most patients were females (n = 35, 83.3%) and median age was 61 yr (range 23-88 yr). Median tumor volume and diameter were 5 cc and 3 cm, respectively, with a median follow-up of 62.3 mo (3.4-218.6 mo). Overall, 20 patients (47.6%) improved clinically and 14 (33.3%) remained unchanged at last follow-up. New onset or worsening of hearing loss was noted in 6 patients (17.2%) after SRS. The median prescription dose to the tumor margin was 15 Gy (12-18 Gy). Median reduction in tumor volume and maximum tumor diameter at last follow-up was 33.3% and 11.54%, respectively. The 5-yr and 10-yr tumor control rates were 87% ± 6% and 69% ± 13%, respectively. There was no correlation between maximum or mean dose to the internal acoustic canal and post-GK hearing loss (P > .05). CONCLUSION SRS is safe and effective in patients with GJTs and results in durable, long-term control. SRS has lower morbidity than that associated with surgical resection, particularly lower cranial nerve dysfunction, and can be a first-line management option in these patients.

Abstract
OBJECTIVE To evaluate the safety and efficacy of SRS treatment of central neurocytomas (CNCs), cavernous sinus hemangiomas (CSHs), and glomus tumors (GTs); and to compare upfront stereotactic radiosurgery (SRS) and adjuvant SRS in the treatment of these hypervascular tumors. METHODS This was a retrospective review of consecutive CNCs, CSHs, and GTs treated with SRS between 1993 and 2017. Tumor response was categorized based on volumetric analysis on magnetic resonance imaging: (1) tumor regression [> 10% decrease in tumor volume (TV)]; (2) stable tumor (≤ 10% change in TV); or (3) tumor progression (> 10% increase in TV). RESULTS Sixty hypervascular tumors (CNC: 28; CSH: 16; GT: 16) underwent SRS between 1993 and 2017. Margin doses were 13 Gy, 12 Gy, and 14 Gy for CNCs, CSHs, and GTs, respectively. Tumor regression was observed in 54 tumors (90%) with initial SRS after a median follow-up of 82 months. Relative reductions in TVs for CNCs were 38%, 52%, and 73% at 12, 24, and 48 months, respectively. Relative reductions in TVs for CSHs were 51%, 68%, and 88% at 12, 24, and 48 months, respectively. Relative reductions in TVs for GTs were 22%, 31%, and 47% at 12, 24, and 48 months, respectively. Upfront SRS was performed in 26 patients (43%). No difference in relative TV reductions were found between upfront and adjuvant SRS. Adverse radiation effects were observed in five patients. No mortality was encountered. CONCLUSION SRS for hypervascular tumors is associated with high rates of tumor regression with low risk of complications. No significant difference in rates of relative TV reduction were found between upfront and adjuvant SRS. Hence, upfront SRS may be considered in select patients.

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
OBJECTIVEThe morbidity of gross-total resection of jugular paraganglioma (JP) is often unacceptable due to the potential for irreversible lower cranial neuropathy. Stereotactic radiosurgery (SRS) has been used at the authors' institution since 1990 for the treatment of JP and other benign intracranial tumors. Conventional means of assessing tumor progression using linear measurements or elliptical approximations are imprecise due to the irregular shape and insinuating growth pattern of JP. The objective of this study was to assess long-term tumor control in these patients by using slice-by-slice 3D volumetric segmentation of serial MRI data.METHODSRadiographic data and clinical records were reviewed retrospectively at a single, tertiary-care academic referral center for patients treated from 1990 to 2017. Volumetric analyses by integration of consecutive tumor cross-sectional areas (tumor segmentation) of serial MRI data were performed. Tumor progression was defined as volumetric growth of 15% or greater over the imaging interval. Primary outcomes analyzed included survival free of radiographic and clinical progression. Secondary outcomes included new or worsened cranial neuropathy.RESULTSA total of 85 patients were treated with Gamma Knife radiosurgery (GKRS) for JP at the authors' institution over the last 27 years. Sixty patients had pretreatment and serial posttreatment contrast-enhanced MRI follow-up suitable for volumetric analysis. A total of 214 MR images were analyzed to segment tumor images in a slice-by-slice fashion to calculate integral tumor volume. The median follow-up duration was 66 months (range 7-202 months). At 5 years the tumor progression-free survival rate was 98%. Three tumors exhibited progression more than 10 years after GKRS. Estimated survival free of radiographic progression rates (95% confidence interval [CI]; n = number still at risk) at 5, 10, and 15 years following radiosurgery were 98% (95% CI 94%-100%; n = 34), 94% (95% CI 85%-100%; n = 16), and 74% (95% CI 56%-98%; n = 6), respectively. One patient with tumor progression required treatment intervention using external beam radiation therapy, constituting the only case of clinical progression. Two patients (3%) without preexisting lower cranial nerve dysfunction developed new ipsilateral vocal fold paralysis following radiosurgery.CONCLUSIONSSRS achieves excellent long-term tumor control for JP without a high risk for new or worsened cranial neuropathy when used in primary, combined modality, or recurrent settings. Long-term follow-up is critical due to the potential for late radiographic progression (i.e., more than 10 years after SRS). As none of the patients with late progression have required salvage therapy, the clinical implications of this degree of tumor growth have yet to be determined.

Abstract
OBJECTIVES The objectives were to evaluate the audiological outcomes, response of symptoms, and response of tumor volume in patients with glomus jugulare tumors treated solely with single fraction gamma knife radiosurgery. STUDY DESIGN Single institution retrospective review. SETTING Academic, tertiary referral center. PATIENTS The diagnosis code for glomus jugulare was used to identify patients. Only those who underwent gamma knife radiosurgery were included. Those previously treated with any modality were excluded. A total of 12 patients were included for the tumor response and symptom response data and 7 of those were included in the audiometric analysis. MAIN OUTCOMES MEASURES Audiometric data at most recent follow-up compared with presentation, subjective improvement in pulsatile tinnitus, and change in tumor volume at most recent follow-up compared with pretreatment. RESULTS The average time to most recent follow-up was 27.6 months. There was no significant change in pure-tone average or word recognition. Pulsatile tinnitus completely resolved or improved in 80% of patients. Cranial neuropathies were stable or improved. A single patient experienced facial nerve paresis 2 years after treatment, which resolved with steroid treatment. Tumor control was 100% and the average change in tumor volume was a decrease of 37%. CONCLUSION Single modality gamma knife radiosurgery treatment of glomus jugulare tumors seems to be safe. Treatment results in decreased tumor volume and improved pulsatile tinnitus in most patients. There was no significant progression of hearing loss after treatment. Lower cranial nerve function remains stable in all patients.

Abstract
Background Paragangliomas are benign neuroendocrine tumors derived from the glomus cells of the vegetative nervous system. Typically, they are located in the region of the jugular bulb and middle ear. The optimal management is controversial and can include surgical excision, stereotactic radiosurgery and embolization. Case Report We report the endovascular approach to three patients harboring glomus jugulare paragangliomas. In all cases incomplete occlusion of the lesions was achieved and recanalization in the follow-up period was revealed. Two patients presented no clinical improvement and the remaining one experienced a transient withdrawal of tinnitus. Conclusions It is technically difficult to achieve complete obliteration of glomus jugulare tumors with the use of embolization and the subtotal occlusion poses a high risk of revascularization and is not beneficial in terms of alleviating clinical symptoms.

Abstract
INTRODUCTION Temporal bone paragangliomas (TBPs) are benign tumors arising from neural crest cells located along the jugular bulbus and the tympanic plexus. In general surgical excision, radiotherapy and wait-and-scan protocols are the main management modalities for TBPs. OBJECTIVE In this paper we aim to present our clinical experience with TBPs and to review literature data. METHODS The patients who were operated for tympanomastoid paraganglioma (TMP) or tympanojugular paraganglioma (TJP) in our clinic in the last 15 years were enrolled in the study. A detailed patient's charts review was performed retrospectively. RESULTS There were 18 (52.9%) cases with TMPs and 16 (47.1%) cases with TJPs, a total of 34 patients operated for TBPs in this time period. The mean age was 50.3± 11.7 (range 25-71 years). The most common presenting symptoms were tinnitus and hearing loss for both TMPs and TJPs. Gross total tumor resection was achieved in 17 (94.4%) and 10 (62.5%) cases for TMPs and TJPs, respectively. Five patients (31.2%) with TJP experienced facial palsy following the operation. For all the patients the mean follow-up period was 25.8 months (range 4-108 months). CONCLUSION In conclusion, based on our findings and literature review, total surgical excision alone or with preoperative embolization is the main treatment modality for TBPs. However radiotherapy, observation protocol and subtotal resection must be considered in cases of preoperative functioning cranial nerves, large tumors and advanced age.

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
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
OBJECTIVE To analyze the long term outcomes after surgery in tympanomastoid paragangliomas. STUDY DESIGN Retrospective study. METHODS The charts of 145 patients with tympanomastoid paragangliomas managed between 1988 and 2013 were reviewed. The clinical features, audiological data, pre- and postoperative notes were noted. The tumors were staged according to the modified Fish and Mattox classification. The surgical approaches for all patients were formulated according to the surgical algorithm developed at our center. RESULTS 34 (23.5%), 46 (31.7%), 22 (15.2%), 18 (12.4%) and 25 (17.2%) patients were diagnosed to have TMP class A1, A2, B1, B2 and B3 tumors respectively. Gross tumor resection was achieved in 141 (97.2%) patients. The facial nerve was uncovered in four patients and infiltrated in three. The cochlea was found eroded in seven cases. The mean follow-up was 48.4 months. Recurrence was seen in one patient (0.7%). In the cases where the facial nerve was preserved (n=143), the nerve function was graded as HB grade 1 in 138 patients (97%). Postoperatively, the mean AC showed an improvement in all categories except in class B2 and B3, which corresponds to the classes that include patients who underwent subtotal petrosectomy. CONCLUSION We report the long term surgical outcomes in tympanomastoid paragangliomas in the largest series published till date. It is possible to completely eradicate all types of tympanomastoid paragangliomas with minimum sequelae by choosing the correct surgical approach to achieve adequate exposure for individual tumor classes as described in our classification and algorithm.

Abstract
OBJECT Glomus tumors usually display indolent behavior, and the effectiveness of radiation in stopping their growth can be assessed after long-term follow-up. Currently only midterm results of radiosurgery are available, so the authors included patients treated by Gamma Knife at least 10 years ago in this study to obtain a perspective of long-term results. METHODS During the period from 1992 to 2003, the Gamma Knife was used to treat 46 patients with glomus tumors. The age of the patients ranged from 21 to 79 years (median 56 years). Gamma Knife radiosurgery was the primary treatment in 17 patients (37%). Open surgery preceded radiosurgery in 46% of cases, embolization in 17%, and fractionated radiotherapy in 4%. The volume of the tumor ranged from 0.2 to 24.3 cm(3) (median 3.6 cm(3)). The minimal dose to the tumor margin ranged between 10 and 30 Gy (median 20 Gy). RESULTS One patient was lost for follow-up after radiosurgery. Clinical follow-up was available in 45 patients and 44 patients were followed with MRI in a follow-up period that ranged from 12 to 217 months (median 118 months). Neurological deficits improved in 19 (42%) of 45 patients and deteriorated in 2 patients (4%). Tumor size decreased in 34 (77%) of 44 patients with imaging follow-up, while an increase in volume was observed in 1 patient (2%) 182 months after radiosurgery and Gamma Knife treatment was repeated. One patient underwent another Gamma Knife treatment for secondary induced meningioma close to the glomus tumor 98 months after initial radiosurgical treatment. Seven patients died 22-96 months after radiosurgery (median 48 months), all for unrelated reasons. CONCLUSIONS Radiosurgery has proved to be a safe treatment with a low morbidity rate and a reliable long-term antiproliferative effect.

Abstract
OBJECTIVE To characterize the clinical presentation, surgical management, and outcomes of a large consecutive cohort of patients with glomus tympanicum (GT) tumors managed at a single tertiary referral group over 4 decades. STUDY DESIGN Retrospective review. SETTING Tertiary neurotological referral center. SUBJECTS AND METHODS All patients underwent surgical treatment of histopathologically confirmed GT between January 1973 and March 2014. Audiometric outcomes were reported according to AAO-HNS guidelines, and tumor stage was described using the Glasscock-Jackson classification system. RESULTS There were 115 patients (90.4% women; mean age, 55.2 years) who met the inclusion criteria; 38 (33.0%) cases of GT were stage I, 51 (44.3%) stage II, 10 (8.7%) stage III, and 16 (13.9%) stage IV. There were 108 (93.9%) patients who underwent gross total removal, while 7 (6.1%) received less than complete resection for advanced disease that was adherent to the petrous carotid artery, facial nerve, stapes footplate, or round window. Two patients who underwent gross total resection experienced transient facial paresis, and 1 had internal carotid injury with stroke. No patients had been diagnosed with recurrent disease at a mean follow-up of 30.4 months. CONCLUSION Surgery remains the treatment of choice for GT, providing a high rate of tumor control and resolution of aural symptoms with a low risk of complications. The surgical approach and extent of resection should be tailored to the patient. Gross total resection can be performed in over 90% of patients; however, leaving a limited adherent tumor remnant on the facial nerve or carotid artery should be considered with advanced infiltrative disease to prevent unnecessary morbidity.

Abstract
The primary treatment goal of radiotherapy for paragangliomas of the head and neck region (HNPGLs) is local control of the tumor, i.e. stabilization of tumor volume. Interestingly, regression of tumor volume has also been reported. Up to the present, no meta-analysis has been performed giving an overview of regression rates after radiotherapy in HNPGLs. The main objective was to perform a systematic review and meta-analysis to assess regression of tumor volume in HNPGL-patients after radiotherapy. A second outcome was local tumor control. Design of the study is systematic review and meta-analysis. PubMed, EMBASE, Web of Science, COCHRANE and Academic Search Premier and references of key articles were searched in March 2012 to identify potentially relevant studies. Considering the indolent course of HNPGLs, only studies with ≥ 12 months follow-up were eligible. Main outcomes were the pooled proportions of regression and local control after radiotherapy as initial, combined (i.e. directly post-operatively or post-embolization) or salvage treatment (i.e. after initial treatment has failed) for HNPGLs. A meta-analysis was performed with an exact likelihood approach using a logistic regression with a random effect at the study level. Pooled proportions with 95% confidence intervals (CI) were reported. Fifteen studies were included, concerning a total of 283 jugulotympanic HNPGLs in 276 patients. Pooled regression proportions for initial, combined and salvage treatment were respectively 21%, 33% and 52% in radiosurgery studies and 4%, 0% and 64% in external beam radiotherapy studies. Pooled local control proportions for radiotherapy as initial, combined and salvage treatment ranged from 79% to 100%. Radiotherapy for jugulotympanic paragangliomas results in excellent local tumor control and therefore is a valuable treatment for these types of tumors. The effects of radiotherapy on regression of tumor volume remain ambiguous, although the data suggest that regression can be achieved at least in some patients. More research is needed to identify predictors for treatment success.
