Role of Endoscopy in Treatment of Complex Hydrocephalus in Children.

Complex hydrocephalus or loculated hydrocephalus is a challenging problem in the field of pediatric neurosurgery. Early diagnosis and treatment are paramount in order to ensure success of treatment. Therefore, alertness is required among pediatricians who are dealing with premature children and children having meningitis and/or intraventricular hemorrhage. Disproportionate hydrocephalic changes in CT scan of the brain are suspicious, whereas gadolinium-enhanced multiplanar MR imaging (axial, sagittal, and coronal) is the best diagnostic modality. The definitive treatment is surgical, yet the approach remains a matter of debate. Cyst fenestration, communicating the isolated compartments together and with the ventricular system, is the main strategy of treatment. Cyst fenestration can be performed through either microsurgery or endoscopy, in order to improve the hydrocephalus, decrease number of shunts, and reduce shunt revision rates. However, the endoscopic procedure has an advantage over microsurgery of being simple and minimally invasive. It is evident that uniloculated hydrocephalus carries better prognosis than multiloculated hydrocephalus; this can be attributed to the initial pathological disease contributing to the ventricular compartmentalization. Because of the bad prognosis in multiloculated hydrocephalus, and because there are few numbers of patients available in any given center, a multicentric prospective study with long-term follow-up evaluating the results of outcome and quality of life is warranted.

Endoscopic third ventriculostomy for management of hydrocephalus associated with Chiari malformation type II in children.

BACKGROUND: Hydrocephalus is commonly associated with Chiari malformation (CM) particularly CM type II. The traditional treatment of hydrocephalus in these patients has been cerebrospinal fluid diversion by shunts. Endoscopic third ventriculostomy (ETV) has emerged as an alternative procedure in these patients. PURPOSE: Assessment of the clinical and radiological outcomes of ETV in the management of hydrocephalus in children with CM II. METHODS: This is a prospective study conducted on 18 patients with CM II associated with hydrocephalus admitted to Cairo University hospitals between January 2020 and June 2021. These patients had been managed surgically by ETV. Clinical outcome was assessed based on improvement of manifestations of increased intracranial pressure while radiological outcome was based on the findings of postoperative computed tomography. In cases with early failure, serial lumbar puncture (LP) was performed for 2 days. RESULTS: ETV was performed as a secondary procedure in 4 cases. The overall success rate of the procedure was 72%, and its success rate as a secondary procedure was 100%. Serial LP was effective in decreasing early failure in 44.4% of cases. Radiological regression of hydrocephalic changes was detected in 50% of the cases. CONCLUSION: ETV is an efficient and safe procedure in the treatment of hydrocephalus in children with Chiari malformation II, particularly when performed as a secondary procedure. Serial LP following the procedure increases the success rate in patients with early failure.

Endoscopic treatment of intracranial cysts in infants: personal experience and review of literature.

BACKGROUND: A wide variety of intracranial cysts is known to occur in infants. If symptomatic, they require treatment; the ideal surgical treatment and indications of surgery are yet a matter of discussion. Traditional treatment is either by cystoperitoneal shunting, or microsurgical fenestration. Endoscopic treatment is an alternative procedure that avoids the invasiveness of open craniotomy and the complications caused by shunting. METHODS: This article reviews the endoscopic treatment of intracranial cysts in infants. The author presents personal experience by reviewing the results of endoscopic treatment in different subgroups among his series of pediatric patients extending over 20 years. RESULTS: Different types of intracranial cysts in infants were discussed and the role of endoscopy in the management of these patients was reviewed. The author also presented the results of endoscopic treatment of a personal series including 87 infants with intracranial cysts operated by the endoscopic procedure. CONCLUSIONS: It has been recommended to use the endoscopic procedure in the treatment of intracranial cysts in infants, because it is effective, simple, minimally invasive, and associated with low morbidity and mortality rates. However, an important prerequisite is the presence of an area of contiguity with the subarachnoid cisterns and/or the ventricular system.

Neurosurgical education in Egypt and Africa.

OBJECTIVE: Africa still significantly lags in the development of neurosurgery. Egypt, located in North Africa, is well-developed in this specialty, with the largest number of neurosurgeons among all African countries. This article provides insight into neurosurgical training in Egypt, the challenges African neurosurgeons are facing, and the requirements needed to enhance neurosurgical education and build up the required neurosurgical capacity in Africa. METHODS: The information presented in the current work was collected from databases of the Egyptian Society of Neurological Surgeons and the World Federation of Neurosurgical Societies. RESULTS: There are two types of neurosurgical certification in Egypt. The first type is granted by the universities (MD), and the second is awarded by the Ministry of Health (Fellow of Neurosurgery). The program in both types ranges from 6 to 9 years. The number of qualified neurosurgeons in Egypt constitutes one-third of the total number of African neurosurgeons. There is a significant shortage of neurological surgeons in Africa, and the distribution is entirely unbalanced, with the majority of neurosurgeons concentrated in the North and South regions. The most important challenge facing neurosurgery in Africa is lack of resources, which is considered to be the main obstacle to the development of neurosurgery. Other challenges include the limited number of neurosurgeons, lack of training programs, and lack of collaboration among the different regions. CONCLUSIONS: Proper collaboration among the different regions within the African continent regarding neurosurgical education will enhance African neurosurgical capacity and make neurosurgery an independent specialty. The definite functional polarity among different regions, regarding both the number of qualified neurosurgeons and the neurosurgical capacity, is an important factor that could help in the development of neurosurgery in this continent.

Virtual learning during the COVID-19 pandemic: a turning point in neurosurgical education.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has caused dramatic changes in medical education. Social distancing policies have resulted in the rapid adoption of virtual learning (VL) by neurosurgeons as a method to exchange knowledge, but it has been met with variable acceptance. The authors surveyed neurosurgeons from around the world regarding their opinions about VL and how they see the future of neurosurgical conferences. METHODS: The authors conducted a global online survey assessing the experience of neurosurgeons and trainees with VL activities. They also questioned respondents about how they see the future of on-site conferences and scientific meetings. They analyzed responses against demographic data, regions in which the respondents practice, and socioeconomic factors by using frequency histograms and multivariate logistic regression models. RESULTS: Eight hundred ninety-one responses from 96 countries were received. There has been an increase in VL activities since the start of the COVID-19 pandemic. Most respondents perceive this type of learning as positive. Respondents from lower-income nations and regions such as Europe and Central Asia were more receptive to these changes and wanted to see further movement of educational activities (conferences and scientific meetings) into a VL format. The latter desire may be driven by financial savings from not traveling. Most queried neurosurgeons indicated that virtual events are likely to partially replace on-site events. CONCLUSIONS: The pandemic has improved perceptions of VL, and despite its limitations, VL has been well received by the majority of neurosurgeons. Lower-income nations in particular are embracing this technology. VL is still evolving, but its integration with traditional in-person meetings seems inevitable.

Consensus statement from the International Consensus Meeting on the Role of Decompressive Craniectomy in the Management of Traumatic Brain Injury : Consensus statement.

BACKGROUND: Two randomised trials assessing the effectiveness of decompressive craniectomy (DC) following traumatic brain injury (TBI) were published in recent years: DECRA in 2011 and RESCUEicp in 2016. As the results have generated debate amongst clinicians and researchers working in the field of TBI worldwide, it was felt necessary to provide general guidance on the use of DC following TBI and identify areas of ongoing uncertainty via a consensus-based approach. METHODS: The International Consensus Meeting on the Role of Decompressive Craniectomy in the Management of Traumatic Brain Injury took place in Cambridge, UK, on the 28th and 29th September 2017. The meeting was jointly organised by the World Federation of Neurosurgical Societies (WFNS), AO/Global Neuro and the NIHR Global Health Research Group on Neurotrauma. Discussions and voting were organised around six pre-specified themes: (1) primary DC for mass lesions, (2) secondary DC for intracranial hypertension, (3) peri-operative care, (4) surgical technique, (5) cranial reconstruction and (6) DC in low- and middle-income countries. RESULTS: The invited participants discussed existing published evidence and proposed consensus statements. Statements required an agreement threshold of more than 70% by blinded voting for approval. CONCLUSIONS: In this manuscript, we present the final consensus-based recommendations. We have also identified areas of uncertainty, where further research is required, including the role of primary DC, the role of hinge craniotomy and the optimal timing and material for skull reconstruction.

Endoscopic treatment of intraventricular ependymal cysts in children: personal experience and review of literature.

OBJECT: Intracranial ependymal cysts are rare neuroepithelial cysts that occur less frequently than arachnoid cysts. The cysts are most often intraparenchymal, but they are rarely reported to be intraventricular. This study evaluates the role of endoscopy in the treatment of intraventricular ependymal cysts (IVECs). METHODS: Twelve pediatric patients (mean age 4.3 years) with symptomatic IVECs were the subject of this study. The cyst was located inside the lateral ventricle in all cases (100%), it was present in trigone (10 patients, 83.3%), and in temporal horn (2 patients, 16.7%). Concomitant hydrocephalus was present in two patients (16.7%). All patients underwent operations through a purely endoscopic procedure. Communication of the cyst with the subarachnoid space was performed in six patients (50%); endoscopic cystocisternostomy was performed in four patients (33.3%), and endoscopic cystoventriculostomy in two patients (16.7%). RESULTS: Postoperative clinical improvement associated with postoperative reduction in cyst size was encountered in ten patients (83.3%). Improvement of hydrocephalus occurred in both patients who had hydrocephalus (100%). There were no deaths or permanent morbidity. Among the follow-up period (mean 44.3 months), none of the patients required a repeat endoscopic procedure due to recurrence of symptoms or increase in cyst size. CONCLUSION: Intraventricular ependymal cysts can be effectively treated by endoscopy. Endoscopic fenestration of the cyst wall into subarachnoid space, basal cisterns, or ventricular system can be used in the treatment of these patients with postoperative symptomatic improvement and reduction of cyst size. The procedure is simple, effective, minimally invasive, and associated with low morbidity and mortality rates.

On the balance beam: facing the challenges of neurosurgical education in the third millennium.

Background: Neurosurgery is one of the most complex and challenging areas of medicine, and it requires an ongoing commitment to education and expertise. Preparing young neurosurgeons with comprehensive education that can allow them to achieve high professional standards is a pivotal aspect of our profession. Methods: This paper aims to analyze the current scenario in neurosurgical training identifying innovative methods that can guarantee the highest level of proficiency in our specialty. Results: Given the inherent high-stakes nature of neurosurgical procedures, there is a significant burden of responsibility in ensuring that neurosurgical training is of the highest caliber, capable of producing practitioners who possess not just theoretical knowledge but also practical skills and well-tuned judgment. Conclusion: Providing high-quality training is one of the major challenges that the neurosurgical community has to face nowadays, especially in low- and middle-income countries; one of the main issues to implementing neurosurgery worldwide is that the majority of African countries and many areas in Southeast Asia still have few neurosurgeons who encounter enormous daily difficulties to guarantee the appropriate neurosurgical care to their population.

Cystic dilatation of the ventriculus terminalis: A narrative review.

Introduction: The terminal ventricle, also known as the fifth ventricle, is a tiny relic cavity in the conus medullaris of the human spinal cord. Our purpose in bringing attention to this condition is to get the word out about the signs and symptoms, diagnostic hurdles, and therapeutic options available for it. Methods: All relevant studies involving patients diagnosed with ventriculus terminalis (VT) were retrieved from PubMed, Google Scholar, and Scopus. Studies published in complete English language reports were included. The terms VT, terminal ventricle, and 5th ventricle. Age, gender, presenting symptoms, magnetic resonance imaging findings, treatment, and outcome of patients with ventriculus terminalis were all included and recorded. Results: The average age of the patients was 39 years, and there were 13 men among them (14.4%). Motor deficits and sciatica were the most commonly reported symptoms in 38 and 34 patients (42.2%, 37.7%), respectively. In 48 patients (53.3%), cyst fenestration was performed, and in 25 patients (27.7%), myelotomy was performed. Fifty-eight patients (64.4%) saw a reduction in cyst size after surgery. The majority of patients reported an improvement in their symptoms in 64 cases (51.1%), with only three cases (3.3%) reporting a worsening. Conclusions: In cases where the VT is the source of symptoms such as motor, sensory, or bladder dysfunction, surgical intervention is recommended. This review compiles information from the available literature to shed light on the anatomy, clinical presentation, imaging, and treatment options for this variant. It also aims to pinpoint any potential drawbacks or restrictions connected to the surgical techniques.

Long-term outcome of surgical management of adult Chiari I malformation.

Chiari I malformation continues to inspire controversy. Debate still exists about surgical options. The aim of this study is to evaluate the long-term outcome of posterior fossa decompression procedure (PFD) in the treatment of adult Chiari I malformation, focusing on some factors or technical aspects which might influence the outcome. Forty-six adult patients with Chiari I malformation operated by PFD are the subject of this study. The group included 21 males and 25 females, with mean age of 37.4 years. Patients were divided into two groups: group I (32 cases) with syringomyelia and group II (14 cases) without syringomyelia. Group I was further subdivided into three subgroups according to the surgical procedure adopted: group Ia (12 cases) operated by PFD only, group Ib (14 cases) operated by PFD with fourth ventricular shunt, and group Ic (six cases) operated by PFD and syringosubarachnoid shunt. All cases included in group II were operated by PFD only. In group I, symptoms improved in 14 cases (43.8 %) and stabilized in 18 cases (56.3 %), whereas in group II, symptoms resolved in ten cases (71.4 %) and improved in four cases (28.6 %). Postoperative magnetic resonance imaging showed that the syrinx was resolved in 21 cases (65.6 %), improved in seven cases (21.9 %), and unchanged in four cases (12.5 %). Among the mean follow-up period (5.8 years), recurrence of symptoms occurred in five cases (10.9 %), all of them are included in group I, and were reoperated again. Posterior fossa decompression is recommended as the treatment of choice in adult Chiari I malformation with or without syringomyelia. The presence of syringomyelia predicts a less favorable response to surgical intervention. Syringosubarachnoid shunting did not improve the long-term outcome either clinically or radiologically. Implanting a fourth ventricular shunt in cases of syringomyelia associated with adhesions at the foramen of Magendie decreases the long-term incidence of recurrence significantly. For recurrent cases, re-exploration of the initial posterior fossa decompression is recommended before any consideration is given for direct management of the syrinx.

Endoscopic third ventriculostomy versus ventriculoperitoneal shunt in the treatment of obstructive hydrocephalus due to posterior fossa tumors in children.

OBJECT: This study compares endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) in the treatment of pediatric patients with marked obstructive hydrocephalus due to midline posterior fossa tumors. METHODS: Fifty-three pediatric patients with a midline posterior fossa tumor (32 medulloblastomas and 21 ependymomas) associated with marked hydrocephalus were studied. Patients were divided into two groups: group A (32 patients) operated by ETV with a mean follow-up of 27.4 months and group B (21 patients) operated by VPS with a mean follow-up of 25 months. RESULTS: Both procedures proved to be effective clinically and radiologically. In group A, intraoperative bleeding occurred in two cases (6.2%) and cerebrospinal fluid leakage in one case (3.1%). In group B, shunt infection occurred in two cases (9.4%), one of these two cases died 4.5 months postoperatively from ventriculitis. Subdural collection occurred in two cases (9.4%), epidural hematoma in one case (4.7%), and upward brain herniation in one case (4.7%). Endoscopic third ventriculostomy proved to be superior due to shorter duration of surgery (15 min versus 35 min), lower incidence of morbidity (9.3% versus 38%), no mortality (0% versus 4.7%), and lower incidence of procedure failure (6.2% versus 38%). CONCLUSION: The shorter duration of surgery, the lower incidence of morbidity, the absence of mortality, the lower incidence of procedure failure, and the significant advantage of not becoming shunt dependent make ETV be recommended as the first choice in the treatment of pediatric patients with marked obstructive hydrocephalus due to midline posterior fossa tumors.

Neurosurgical Wrong Surgical Site in Lower-Middle- or Low-Income Countries (LMICs): A Survey Study.

BACKGROUND: One of the most preventable errors of a surgeon's career is operating on the incorrect surgical site (ICSS). No study in any specialty has ever investigated the incidence of ICSS events in lower-income countries. This study focuses on identifying the occurrence of these events along with an analysis of potential causes leading to these unfortunate events. METHODS: The authors distributed a survey to neurosurgical colleagues from around the world. These surgeons were first asked to identify details about their practice and incidence and personal experience with ICSS in their own careers. At the end of the survey, they responded to questions about their knowledge of safety checklists. RESULTS: In this study there was a 63.4% response rate. When combined with those who participated through various social media platforms, there were 178 responses. The incidence rate for every 10,000 cases performed was found to be 22.8 in the cranial group, 88.6 in the cervical group, and 158.8 in the lumbar procedural group. This study identified that 40% of participants had never learned or experienced the ABCD time-out strategy and that 60% of surgeons did not use intraoperative navigation or imaging in their practices. The error has never been disclosed to the patient in 48% of the ICSS cases. CONCLUSIONS: Due to a lack of application of safety checklist protocol, there is an increased occurrence of ICSS events in lower-income countries. The results of this study demonstrate the necessity of investing time and resources dedicated to avoiding preventable errors.

The Impact of COVID-19 on Neurosurgical Services in Africa.

INTRODUCTION: COVID-19 has affected the global provision of neurosurgical services. We sought to review the impact of COVID-19 on the neurosurgical services in Africa. METHODS: A cross-sectional survey was distributed to African neurosurgeons seeking to review demographics, national and neurosurgical preparedness, and change in clinical services in April 2020. RESULTS: A total of 316 responses from 42 countries were received. Of these, 81.6% of respondents were male and 79.11% were under the age of 45 years. In our sample, 123 (38.92%) respondents were in training. Most (94.3%) respondents stated they had COVID-19 cases reported in their country as of April 2020. Only 31 (41.50%) had received training on managing COVID-19. A total of 173 (54.70%) respondents were not performing elective surgery. There was a deficit in the provision of personal protective equipment (PPE): surgical masks (90.80%), gloves (84.80%), N95 masks (50.80%), and shoe covers (49.10%). Health ministry (80.40%), World Health Organization (74.50%), and journal papers (41.40%) were the most common sources of information on COVID-19. A total of 43.60% had a neurosurgeon in the COVID-19 preparedness team; 59.8% were concerned they may contract COVID-19 at work with a further 25.90% worried they may infect their family. Mental stress as a result of COVID-19 was reported by 14.20% of respondents. As of April 2020, 73.40% had no change in their income. CONCLUSIONS: Most African countries have a national COVID-19 policy response plan that is not always fully suited to the local neurosurgery services. There is an ongoing need for PPE and training for COVID-19 preparedness. There has been a reduction in clinical activities both in clinic and surgeries undertaken.

A Continental Survey on the Impact of COVID-19 on Neurosurgical Training in Africa.

BACKGROUND: Containment measures for COVID-19 have affected surgical training globally. We sought to assess how neurosurgical training has been affected across Africa in April 2020. METHODS: A cross-sectional survey was distributed to African Neurosurgical trainees seeking to review demographics and effects of COVID on training. RESULTS: A total of 123 neurosurgery trainees responded from 23 African countries and a further 6 were abroad. A total of 91.80% were men, and 96.70% were training in public institutions. Only 41% had received training in COVID-19 with 61.79% worried that they would contract COVID-19 while performing their clinical duties. There was a marked reduction in clinical activities including a median reduction of elective surgery (-80%), clinics (-83%), and emergency surgery (-38.50%). A total of 23.58% of residents did not receive a formal salary, with 50% on less than $1000 USD gross per month. CONCLUSIONS: This is the first continental survey of neurosurgery trainees in Africa. COVID-19 has significantly affected clinical and learning opportunities. There are concerns of the long-term effects on their training activities for an uncertain period of time during this pandemic. Although there has been a global increase in e-learning, there is need to evaluate if this is accessible to all trainees.

Needs of Young African Neurosurgeons and Residents: A Cross-Sectional Study.

Introduction: Africa has many untreated neurosurgical cases due to limited access to safe, affordable, and timely care. In this study, we surveyed young African neurosurgeons and trainees to identify challenges to training and practice. Methods: African trainees and residents were surveyed online by the Young Neurosurgeons Forum from April 25th to November 30th, 2018. The survey link was distributed via social media platforms and through professional society mailing lists. Univariate and bivariate data analyses were run and a P-value < 0.05 was considered to be statistically significant. Results: 112 respondents from 20 countries participated in this study. 98 (87.5%) were male, 63 (56.3%) were from sub-Saharan Africa, and 52 (46.4%) were residents. 39 (34.8%) had regular journal club sessions at their hospital, 100 (89.3%) did not have access to cadaver dissection labs, and 62 (55.4%) had never attended a WFNS-endorsed conference. 67.0% of respondents reported limited research opportunities and 58.9% reported limited education opportunities. Lack of mentorship (P = 0.023, Phi = 0.26), lack of access to journals (P = 0.002, Phi = 0.332), and limited access to conferences (P = 0.019, Phi = 0.369) were associated with the country income category. Conclusion: This survey identified barriers to education, research, and practice among African trainees and young neurosurgeons. The findings of this study should inform future initiatives aimed at reducing the barriers faced by this group.

Do neurosurgeons follow the guidelines? A world-based survey on severe traumatic brain injury.

BACKGROUND: Traumatic brain injury (TBI) is going to be the third-leading cause of death worldwide, according to the WHO. Two European surveys suggested that adherence to brain trauma guidelines is poor. No study has compared compliance between low- (LMICs) and high-income (UHICs) countries. Hence, this study aimed to investigate differences in the management of severe TBI patients, comparing low- and high-income, and adherence to the BTF guidelines. METHODS: A web-based survey was spread through the Global Neuro Foundation, different neurosurgical societies, and social media. RESULTS: A total of 803 neurosurgeons participated: 70.4 from UHICs and 29.6% from LMICs. Hypertonic was administered as an early measure by the 73% and 65% of the responders in LMICs and UHICs, respectively (P=0.016). An invasive intracranial pressure monitoring was recommended by the 66% and 58% of the neurosurgeons in LMICs and UHICs, respectively (P<0.001). Antiseizure drugs (P<0.001) were given most frequently in LMICs as, against recommendations, steroids (87% vs. 61% and 86% vs. 81%, respectively). In the LMICs both the evacuation of the contusion and decompressive craniectomy were performed earlier than in UHICs (30% vs. 17% with P<0.001 and 44% vs. 28% with P=0.006, respectively). In the LMICs, the head CT control was performed mostly between 12 and 24 hours from the first imaging (38% vs. 23%, P<0.001). CONCLUSIONS: The current Guidelines on TBI do not always fit to both the resources and circumstances in different countries. Future research and clinical practice guidelines should reflect the greater relevance of TBI in low resource settings.

The safety and efficacy of anterior versus posterior decompression surgery in degenerative cervical myelopathy: a prospective randomized trial.

OBJECTIVE: The safety and efficacy of anterior and posterior decompression surgery in degenerative cervical myelopathy (DCM) have not been validated in any prospective randomized trial. METHODS: In this first prospective randomized trial, the patients who had symptoms or signs of DCM were randomly assigned to undergo either anterior cervical discectomy and fusion or posterior laminectomy with or without fusion. The primary outcome measures were the change in the visual analog scale (VAS) score, Neck Disability Index (NDI), and Nurick myelopathy grade 1 year after surgery. The secondary outcome measures were intraoperative and postoperative complications, hospital stay, and Odom's criteria. The follow-up period was at least 1 year. RESULTS: A total of 68 patients (mean age 53 ± 8.3 years, 72.3% men) underwent prospective randomization. There was a significantly better outcome in the NDI and VAS scores in the anterior group at 1 year (p < 0.05). Nurick myelopathy grading showed nonsignificant improvement using the posterior approach group (p = 0.79). The mean operative duration was significantly longer in the anterior group (p < 0.001). No significant difference in postoperative complications was found, except postoperative dysphagia was significantly higher in the anterior group (p < 0.05). There was no significant difference in postoperative patient satisfaction (Odom's criteria) (p = 0.52). The mean hospital stay was significantly longer in the posterior group (p < 0.001). CONCLUSIONS: Among patients with multilevel DCM, the anterior approach was significantly better regarding postoperative pain, NDI, and hospital stay, while the posterior approach was significantly better in terms of postoperative dysphagia and operative duration.

Endoscopic treatment of third ventricular colloid cysts: a review including ten personal cases.

The surgical treatment of colloid cysts has been traditionally difficult with high rate of postoperative complications. The variety of surgical options reflects the technical difficulty in removing these benign lesions with low morbidity. Microsurgical removal has for years been considered the "gold standard" of treatment, with the use of either a transcortical-transventricular or a transcallosal approach. Neuroendoscopic management is emerging as a safe, effective alternative to microsurgery. The present review discusses the role of endoscopy in the surgical treatment of third ventricular colloid cysts focusing on some factors, which might influence the outcome. The results have been presented from the literature and supplemented by the results of treating ten personal cases of third ventricular colloid cysts who were operated endoscopically in the Neurosurgical Department, Cairo University. This study aims at evaluating the endoscopic approach as a surgical line of treatment in the management of third ventricular colloid cysts and to see if it has already become superior over microsurgery.
