OBJECTIVES: To compare the effectiveness of Endoscopic (endonasal transsphenoidal) repair of CSF leak with transcranial approach in terms of post-operative complications.  METHODOLOGY:   This study was conducted in the Department of Neurosurgery, Lady Reading Hospital, Peshawar. Total of 40 patients diagnosed according to inclusion criteria were enrolled and were divided into two groups. One group was treated with endonasal trans-sphenoidal repair, and another was treated with a trans-cranial approach. All patients were followed for 1 year.  RESULTS:  The mean age of enrolled patients was 35.4±11.6 years. There were 62.5% male and 37.5% female. In the endoscopic group the recurrence rate was observed in 3 (15%) of the patients while in the trans-cranial group the recurrence rate was observed in 2 (10%) of the patients. The overall recurrence and success rate was 8% and 92% respectively. About 4 patients developed an infection, which was treated successfully.  CONCLUSION:  It is concluded that the endoscopic approach is safe and effective. The endoscopic approach should be considered as standard procedure for treatment.

Objective: The aim of this study is to compare the outcome of endoscopic endonasal verus transcranial approach for cerebrospinal fluid leak repair. Study Design: Comparative study Place and Duration: Conducted at department of Neurosurgery, Mardan Medical Complex/ Bacha Khan Medical College, Mardan during the period from 1st January 2020 to 31st December 2021. Methods: Total eighty patients of both genders were presented in this study. Patients were aged between 20-65 years. Patients’ detailed demographics age, sex and body mass were recorded after taking written consent. Patients had CSF leaks and the history of CSF leak was presented. Patients were equally divided into two groups, I and II. Group I received endonasal technique and group II received transcranial approach. All the patients underwent MRI and CT scan. Complete follow up among both groups were taken in the duration of 8 months for the assessment of efficacy. Complete data was analyzed by SPSS 24.0 version. Results: Mean age of the patients in group I was 33.08±14.90 years with mean BMI28.4±3.12 kg/m2 and in group II mean age was 31.66±4.84 years with mean BMI 27.45±1108 kg/m2. Total 50 (62.5%) patients were males (25 in each group) and 30 (37.5%) patients were females (15 in each group). In group I recurrence rate was found in 3 (7.5%) cases and in group II recurrence rate was 6 (15%). 3 (7.5%) patients in group II developed infection but no infection rate was found in the endoscopic endonasal group. Satisfaction among patients in the endonasal group was greater than that of the transcranial group. Overall efficacy rate among both groups was 71 (88.8%). Conclusion: We concluded in this study that for repair of cerebrospinal fluid leak endoscopic endonasal approach was effective and safe method as compared to transcranial approach. Minimum rate of recurrence and high rate of recovery was fund in endonasal approach. Keywords: CSF, Endoscopic endonasal, Transcranial approach, Complications, Recurrence

Objectives Extended endoscopic approaches are useful for resection of selected craniopharyngiomas. Midline, extraventricular, and predominantly cystic lesions are good candidates for endoscopic resection. In this video, we demonstrate the endoscopic endonasal resection of a large suprasellar craniopharyngioma and discuss the nuances of the surgical technique. Design/Setting Surgical video of an extended endoscopic approach for resection of a suprasellar craniopharyngioma. Results We report the case of a 56-year-old woman who presented with bitemporal hemianopsia and visual acuity deterioration secondary to a large suprasellar solid–cystic lesion. The patient underwent an extended endoscopic transtuberculum approach for resection of the lesion, which was diagnosed as a papillary craniopharyngioma. This video discusses the anatomy and surgical technique applied for endoscopic resection of such lesions. Conclusion Endoscopic endonasal surgery is a useful technique for management of craniopharyngiomas. It is associated with good clinical outcomes in selected cases. Complications, such as postoperative CSF leak, may occur and should be carefully managed.The link to the video can be found at: https://youtu.be/EneOCiQE7yo.

<b><i>Introduction:</i></b> Endoscopic endonasal surgery (EES) has been slower to gain popularity in early childhood due to anatomical challenges. We sought to describe the safety and efficacy of EES in early childhood. <b><i>Methods:</i></b> All patients younger than 7 years who underwent EES at a large Cranial Base Center from 2002 to 2019 were reviewed as a retrospective cohort study. <b><i>Results:</i></b> Thirty-six patients underwent EES before the age of 7 years. Four patients had two-stage EES. Two patients required combined transcranial and endonasal approaches. The mean age at the time of initial surgery was 4 years (range: 1–6). Twenty patients were male, and 16 were female. Of 21 tumors intended for resection, 11 patients had gross total resections, and 10 had near total (&#x3e;95% tumor removed) resections. Nine patients (43%) had recurrences, of which 6 were craniopharyngiomas (<i>p</i> = 0.01). There was no difference in recurrence rates based on the degree of resection (<i>p</i> = 0.67). Three cerebrospinal fluid (CSF) leaks occurred following primary EES (8%). Following an increase in nasoseptal flap usage (31–52%) and CSF diversion (15–39%) in 2008, there was only one CSF leak out of 23 patients (4 vs. 15%; <i>p</i> = 0.54). Postoperatively, 1 patient developed a permanent new cranial neuropathy, and 1 patient developed a permanent visual field cut. Six patients developed permanent postoperative panhypopituitarism, of which all were craniopharyngiomas (<i>p</i> &#x3c; 0.001). The mean follow-up was 64 months. <b><i>Conclusions:</i></b> Early childhood EES is both safe and technically feasible for a variety of pathologies.

Background: The excellent visualization and minimally invasive approach employed in endoscopic endonasal procedures has now revolutionized the pituitary surgery, replacing the transnasal microscopic technique worldwide. However, it involves major shift in hand-eye co-ordination from static 3 dimensional images of microscope to 2 dimensional endoscopic images hence demands training and inter-disciplinary approach. Here we present our experiences in learning and developing a safe endonasal transsphenoidal endoscopic approach to resect pituitary adenomas.Methods: This prospective study was jointly conducted in the departments of ENT and Neurologicals surgery Kathmandu Medical College, Nepal, from September 2014 to August 2016. The endoscopic approach to the sphenoid sinus was performed by an Otolaryngologist and ablative surgery by Neurosurgeon. The ease of procedure, intra operative challenges, surgical cure, post-operative cerebro spinal fluid (CSF) leaks and postoperative complaints were analyzed.Results: Sixteen consecutive patients with pituitary adenoma (macro adenoma=13, micro adenoma =3) were analyzed. There were three intraoperative CSF leak, managed successfully. Two patients developed transient diabetes insipidus and surgical cure rate was 90%. No case had to be switched over to traditional microscopic route due to technical failure. There was no mortality.Conclusions: The endoscopic endonasal transsphenoidal approach to pituitary tumors is a safe and minimally invasive procedure, which can be employed safely in any of our centers in Nepal, equipped with endoscopic sinus surgery and endoscopically trained ENT and Neurosurgeons. A multi disciplinary approach provides good access, greater tumor excision and excellent postoperative follow up.Keywords: .

Abstract Introduction Decompression of the optic nerve within the optic canal is indicated for compressive visual decline. The two most common approaches utilized for optic canal decompression are a medial approach with an endoscopic endonasal approach and a lateral approach with a craniotomy. Our study is a cadaveric anatomical study comparing the length and circumference of the orbit decompressed via an endoscopic endonasal approach versus a frontotemporal craniotomy. Methods Five cadaveric specimens were utilized. Predissection computed tomography (CT) scans were performed on each specimen. On each specimen, a standard frontotemporal craniotomy with anterior clinoidectomy and superolateral orbital decompression was performed on one side and an endoscopic endonasal approach with medial wall decompression was performed on the contralateral side. Post-dissection CT scans were performed. An independent radiologist provided measurements of the length (mm) and circumference (degrees) of optic canal decompression bilaterally. Results The mean length of optic canal decompression for open and endoscopic approach was 13 mm (range 12–15 mm) and 12.4 mm (range 10–16 mm), respectively. The mean circumference of decompression for open and endoscopic approaches was 252.8 degrees (range 205–280 degrees) and 124.6 degrees (range 100–163 degrees), respectively. Conclusion The endoscopic endonasal and the transcranial approaches provide a similar length of optic canal decompression, but the transcranial approach leads to greater circumferential decompression. The endoscopic endonasal approach has the benefit of being minimally invasive, though. Ultimately, the surgical approach decision should be based on the location of the pathology and the surgeon's comfort.

Abstract Introduction Rathke's cleft cysts (RCC) are generally treated with transsphenoidal fenestration and cyst drainage. If no cerebrospinal fluid (CSF) leak is created, the fenestration can be left open. If CSF is encountered, a watertight closure must be created to prevent postoperative CSF leak, though sellar closure has theoretically been linked with higher recurrence rate. In this study, we investigate the relationship between sellar closure, rate of postoperative CSF leak, and RCC recurrence. Methods Retrospective review of a prospective database of all endoscopic endonasal RCC fenestrations and cases were divided based on closure. The “open” group included patients who underwent fenestration of the RCC, whereas the “closed” group included patients whose RCC was treated with fat and a rigid buttress ± a nasoseptal flap. The rate of intra- and postoperative CSF leak and radiographic recurrence was determined. Results The closed group had a higher rate of suprasellar extension (odds ratio [OR]: 8.0, p = 0.032) and intraoperative CSF leak (p ≤ 0.001). There were 54.8% intraoperative CSF leaks and no postoperative CSF leaks. Radiologic recurrence rate for the closed group (35.0%) was three times higher than the open group (9.1%; risk ratio [RR] = 3.85, p = 0.203), but not powered to show significance. None of the radiologic recurrences required reoperation. Conclusion Maintaining a patent fenestration between an RCC and the sphenoid sinus is important in reducing the rate of radiographic recurrence. Closure of the fenestration may be required to prevent CSF leak. While closure increases the rate of radiographic recurrence, reoperation for recurrent RCC is still an uncommon event.

Cerebrospinal fluid leak represents a frequent complication in Craniopharyngioma´s Endoscopic Endonasal Approach. A descriptive observational investigation was performed in 50 adult patients operated of Craniopharyngiomas by aggressive Expanded Endonasal Endoscopic Approach (EEEA) in “Hermanos Ameijeiras” Hospital since 2010 to 2019 using nasoseptal flap. The 14% of all patients develop CSF leak and 85,7 % of these cases had a great communication into third ventricle creating a cisternoventricular space. Was identified relation with tumor size, hypothalamic invasion and adhesion strength of tumour. Surgical cavity suffered hydrostatic and hydrodynamic pression than lead to CSF leak independent of multilayer reparation.

Background: Extended endonasal solo endoscopic approach for the non-pituitary lesions of the sellar and suprasellar regions are not new in the field of neurosurgery. Following endoscopic surgical approach of the pituitary adenoma, endoscopic neurosurgeon is eager to develop the skill for non-pituitary sellar & suprasellar lesions. Common sellar & suprasellar lesions are pituitary adenoma, craniopharyngioma, tuberculumselle meningioma and suprasellar germinoma. Objective: Traditional transsphenoidal approach gives exposure to the pituitary fossa, whereas extended approach provides exposure to the optic nerve, chiasm, acom complex and basal frontal lobe ,mammillary body, mid brain and laterally to the cavernous sinuses. Material & method: From November 2007 to March 2012, 12 cases of done by extended endonasal solo endoscopic approach among 12 cases of craniopharyngiomas. Patient’s history, clinical findings, pre-operative and post-operative visual acuity, visual field and radiological data were collected and analyzed. All patients underwent solo endoscopic extended transsphenoidal approach with or without nasoseptal flap technique for closure. Most of the patients were given lumbar drain as a treatment for CSF leak. Result: All patients were of age group of 10 to 60 years. Male were 8 (66.67%), female were 4 (33.33%) in number. Gross total removals were done in 7 cases out of 12 (58.33%) craniopharyngiomas and subtotal removal done in 5 (41.67%) cases. Visual acuity and field of vision were improved in all cases of craniopharyngiomas. One case (8.33%) of craniopharyngioma had prolong period of unconsciousness probably from hypothalamic disturbance. CSF leak developed in 2 (16.67%) cases. Patients with craniopharyngioma were required thyroxin and cortisol for replacement. Permanent diabetes insipidus developed in 5 cases (41.67%). Three patients required permanent CSF diversion via a ventriculoperitoneal shunt after documentation of postoperative HCP. There was one case of chemical meningitis, and two cases confirmed bacterial infections. Craniopharyngioma can be successfully resected via a purely endoscopic, endonasal approach. Craniopharyngioma have a higher rate of perioperative hydrocephalus and postoperative CSF leak compared with other tumor types in the same area. Conclusion: Extended transsphenoidal approach is an excellent alternative of skull base approach for the removal of most of the craniopharyngioma.The endoscopic endonasal route provides a good exposure, especially of the sub-chiasmatic and retro-chiasmatic areas, as well as of the stalk– infundibulum axis and the third ventricle chamber. It gives better visualization, improved postoperative visual outcome for less manipulation and low complication then craniotomy. However CSF leak and diabetes insipidus is common known complications which have to be manage promptly and appropriately. Bangladesh Journal of Neuroscience 2013; Vol. 29 (2) : 108-114

OBJECTIVEAnterior skull base meningiomas are benign lesions that cause neurological symptoms through mass effect on adjacent neurovascular structures. While traditional transcranial approaches have proven to be effective at removing these tumors, minimally invasive approaches that involve using an endoscope offer the possibility of reducing brain and nerve retraction, minimizing incision size, and speeding patient recovery; however, appropriate case selection and results in large series are lacking.METHODSThe authors developed an algorithm for selecting a supraorbital keyhole minicraniotomy (SKM) for olfactory groove meningiomas or an expanded endoscopic endonasal approach (EEA) for tuberculum sella (TS) or planum sphenoidale (PS) meningiomas based on the presence or absence of olfaction and the anatomical extent of the tumor. Where neither approach is appropriate, a standard transcranial approach is utilized. The authors describe rates of gross-total resection (GTR), olfactory outcomes, and visual outcomes, as well as complications, for 7 subgroups of patients. Exceptions to the algorithm are also discussed.RESULTSThe series of 57 patients harbored 57 anterior skull base meningiomas; the mean tumor volume was 14.7 ± 15.4 cm3 (range 2.2–66.1 cm3), and the mean follow-up duration was 42.2 ± 37.1 months (range 2–144 months). Of 19 patients with olfactory groove meningiomas, 10 had preserved olfaction and underwent SKM, and preservation of olfaction in was seen in 60%. Of 9 patients who presented without olfaction, 8 had cribriform plate invasion and underwent combined SKM and EEA (n = 3), bifrontal craniotomy (n = 3), or EEA (n = 2), and one patient without both olfaction and cribriform plate invasion underwent SKM. GTR was achieved in 94.7%. Of 38 TS/PS meningiomas, 36 of the lesions were treated according to the algorithm. Of these 36 meningiomas, 30 were treated by EEA and 6 by craniotomy. GTR was achieved in 97.2%, with no visual deterioration and one CSF leak that resolved by placement of a lumbar drain. Two patients with tumors that, based on the algorithm, were not amenable to an EEA underwent EEA nonetheless: one had GTR and the other had a residual tumor that was followed and removed via craniotomy 9 years later.CONCLUSIONSUtilizing a simple algorithm aimed at preserving olfaction and vision and based on maximizing use of minimally invasive approaches and selective use of transcranial approaches, the authors found that excellent outcomes can be achieved for anterior skull base meningiomas.

Abstract BACKGROUND Various approaches can be considered for decompression of the intracanalicular optic nerve. Although clinical experience has been reported, no quantitative study has yet compared the extent of decompression achieved by an endoscopic endonasal versus transcranial approach. OBJECTIVE Toward this aim, our morphometric analysis compared both approaches by quantifying the circumferential degree of optic canal decompression that is possible before any meningeal violation, which would result in cerebrospinal fluid (CSF) leak. METHODS From 10 cadaver heads, 20 optic canals were sequentially decompressed using an endoscopic endonasal approach and pterional craniotomy with extradural clinoidectomy. Dissections ended before violation of the sphenoid sinus during the transcranial approach, and before intracranial transgression from the endonasal corridor. Based on our study criteria, decompressions were not maximal for either approach, but were maximal before violating the other compartment. Decompression achieved from each approach was quantified using CT scans for each stage. RESULTS Greater circumferential bony optic canal decompression was obtained from transcranial (245.2°) than endonasal (114.8°) routes (P &lt; .001). By endonasal perspective, the anatomical point where the optic nerve traverses intracranially was approximated by the medial border of the anterior ascending cavernous internal carotid artery. CONCLUSION Our morphometric analysis comparing optic canal decompression for endonasal and transcranial corridors provides important guidance for this location. Ample visualization and wide exposure can be achieved via a transcranial approach with limited risk of CSF leak. A landmark, where the intracanalicular segment ends and optic nerve traverses intracranially, can mark the extent of decompression safely obtained before risking CSF leak.
