Abstract
BACKGROUND Prolactinomas are common tumours that significantly reduce quality-of-life (QOL) due to sellar mass effect, secondary hypogonadism, and the peripheral effects of prolactin. Understanding the factors that influence QOL would provide insights into therapeutic targets to optimise patient outcomes and improve wellbeing in prolactinoma. METHODS A systematic review was performed in accordance with the PRISMA statement. Studies that reported patient QoL using validated metrics were included. Bias and methodological rigour were assessed using the MINORS criteria. RESULTS A total of 18 studies were identified studies were available for review, comprising 877 patients. Most were small cross-sectional studies at high risk of bias. Prolactinoma exhibit worse QOL than healthy controls, particularly mental and psychosocial wellbeing. QOL is also worse than patients with non-functional adenomas, but better than those with Cushing's disease and acromegaly. QOL correlates with prolactin levels, and approaches population baseline with prolonged biochemical control. Dopamine agonists and surgery both improve overall QOL, however improvements are more rapid with surgery. CONCLUSION Poor quality of life in prolactinoma is multifactorial, related to biochemical control, side effects of therapy, and sellar mass effect. Targeting persistent symptoms, reducing healthcare costs, and reducing side-effects of therapy are avenues to improving QOL in patients with prolactinoma.

Abstract
Foramen magnum meningiomas are challenging lesions owing to their proximity to the lower brainstem, vertebrobasilar system, and lower cranial nerves.1,2 Tumor size, origin, morphology, relationship to neurovascular structures, and bony anatomy determine the optimal surgical approach.2,3 Classically, far lateral approaches have been the workhorse approach to the foramen magnum. Variations of the far lateral including transcondylar and extended transcondylar (paracondylar), with or without transposition of the vertebral artery, are sometimes used for a more lateral approach to the brainstem and clivus. Here, we present a 60-year-old male patient presenting with a large foramen magnum meningioma. Preoperative workup includes computed tomography and MRI with angiography to assess for posterior circulation dominance, anatomic variants including posterior inferior cerebellar artery origin, venous, and bony anatomy.1,4 An extreme far lateral provides access anterior to the vertebral artery to extend exposure beyond the standard far lateral approach. This comprised transcondylar drilling, bony mobilization of the V3 Vertebral artery from C1 foramen transversarium, and dural mobilization of vertebral artery with a dural cuff at its site of dural entry. The patient tolerated the procedure, gross total resection was achieved, and the patient was discharged home. This video demonstrates in detail the steps of exposure, condylar drilling, vertebral artery transposition, and dural opening. These maneuvers can be difficult to conceptualize yet are key to successful extended transcondylar exposure. The patient gave informed consent for surgery and video recording. Institutional Review Board approval was deemed unnecessary.

Abstract
BACKGROUND Supraclinoid Internal Carotid Artery (ICA) aneurysms require additional access to standard pterional craniotomy via extradural clinoidectomy. Existing texts and surgical videos lack clarity, explanation and a clear step by step process. CASE DESCRIPTION We present a case of a ruptured supraclinoid ICA aneurysm and extradural clinoidectomy along with 3D reconstructed imaging of the case anatomy to guide its resection. Real-time unedited on table rerupture provides an example of management. CONCLUSION Extradural Anterior Clinoidectomy is a key maneuver in cerebrovascular surgical armamentarium for clipping of supraclinoid aneurysms. Stereotypical Pathological or Surgical Anatomy, its application, and availability with 3D imaging should be facilitates the framing and learning of normal physiological anatomy.

Abstract
Intradural lumbar disk herniation (ILDH) is a rare variant and accounts for 0.33%-1.5% of lumbar disk herniations. Although clues exist on preoperative imaging, they remain subtle and most cases of ILDH are diagnosed intraoperatively. Intraoperative ultrasound is a useful adjunct in diagnosing and managing ILDH. We present a case to demonstrate the features of an intradural herniated disk on ultrasound imaging and highlight the utility of intraoperative ultrasonography in establishing diagnosis, guiding dural opening, and confirming adequate nerve root decompression following diskectomy.

Abstract
BACKGROUND Headache is a common symptom in patients with pituitary adenomas. Research on whether resection of pituitary adenomas via the endoscopic endonasal approach (EEA) affects headaches is limited, and the pathophysiology of headaches associated with pituitary adenomas remains unclear. This study aimed to determine if resection of pituitary adenomas via the EEA improves headaches and investigate factors that may be associated with headaches in patients with pituitary adenoma. METHODS A prospectively collected database of 122 patients undergoing resection of pituitary adenoma via the EEA was analyzed. Patient-reported headache severity was collected prospectively using the Headache Impact Test (HIT-6) at preoperative baseline and 4 postoperative time points (3 weeks, 6 weeks, 3 months, and 6 months). RESULTS Adenoma size and subtype, cavernous sinus invasion, and hormonal status were not associated with preoperative headache burden. In patients with preoperative headaches (HIT-6 score >36), significant decreases in HIT-6 score were observed postoperatively at 6 weeks (5.5-point improvement, 95% CI 1.27-9.78, P < 0.01), 3 months (3.6-point improvement, 95% CI 0.01-7.18, P < 0.05), and 6 months (7.5-point improvement, 95% CI 3.43-11.46, P < 0.01). The only factor associated with headache improvement was cavernous sinus invasion (P = 0.003). Adenoma size and subtype and hormonal status were not associated with postoperative headache burden. CONCLUSIONS Resection via the EEA is associated with significant improvement in headache-related impact on patient functioning from ≥6 weeks after surgery. Patients with cavernous sinus invasion are more likely to experience improvement in headaches. The mechanism of headaches associated with pituitary adenoma still requires clarification.

Abstract
BACKGROUND Incorrect level spinal surgery is an avoidable complication, with significant ramifications. Several pre-operative spinal marking techniques have been described to aid intraoperative localisation. METHODS A systematic search of Ovid MEDLINE, and EMBASE was performed from inception to July 2022. All publications describing cases of internal spinal marking were included for further analysis. 22 articles describing 503 patients satisfied our eligibility criteria. RESULTS A number of localisation techniques, including endovascular coiling (n = 16), fiducials (n = 177), dye (n = 109), needle/fixed wire (n = 199), cement (n = 4), and gadolinium tubes (n = 1) were described. The highest rates of technical success were observed with endovascular coiling, fiducials, cement and dye (100 %), and complication rates were lowest with endovascular coiling, fiducials and cement (0 %). CONCLUSIONS Overall, internal spinal marking was effective and safe. When considering practicality and efficacy, fiducial marking appears the optimal technique, as it can be performed in the outpatient setting under local anaesthesia. This review demonstrates the need for more targeted investigation into localisation methods in spinal surgery.

Abstract
Water balance is fundamental to all homeostasis. The hypothalamic pituitary adrenal (HPA) axis influences water balance through the effects of corticotropin releasing hormone (CRH) and cortisol on arginine vasopressin (AVP) secretion, and the peripheral effects of cortisol on hemodynamic and renal water handling. In this review, we explore the complex interplay of glucocorticoids with water balance, with particular attention to hyponatremia and pituitary surgery.

Abstract
BACKGROUND MR imaging is key in the diagnostic work-up of Cushing disease. The sensitivity of MR imaging in Cushing disease is not known nor is the prognostic significance of "MR imaging-negative" disease. PURPOSE Our aim was to determine the overall sensitivity and prognostic significance of MR imaging localization of Cushing disease. DATA SOURCES We performed a systematic review of the MEDLINE and PubMed databases for cohort studies reporting the sensitivity of MR imaging for the detection of adenomas in Cushing disease. STUDY SELECTION This study included 57 studies, comprising 5651 patients. DATA ANALYSIS Risk of bias was assessed using the methodological index for non-randomized studies criteria. Meta-analysis of proportions and pooled subgroup analysis were performed. DATA SYNTHESIS Overall sensitivity was 73.4% (95% CI, 68.8%-77.7%), and the sensitivity for microadenomas was 70.6% (66.2%-74.6%). There was a trend toward greater sensitivity in more recent studies and with the use of higher-field-strength scanners. Thinner-section acquisitions and gadolinium-enhanced imaging, particularly dynamic sequences, also increased the sensitivity. The use of FLAIR and newer 3D spoiled gradient-echo and FSE sequences, such as spoiled gradient-echo sequences and sampling perfection with application-optimized contrasts by using different flip angle evolutions, may further increase the sensitivity but appear complementary to standard 2D spin-echo sequences. MR imaging detection conferred a 2.63-fold (95% CI, 2.06-3.35-fold) increase in remission for microadenomas compared with MR imaging-negative Cushing disease. LIMITATIONS Pooled analysis is limited by heterogeneity among studies. We could not account for variation in image interpretation and tumor characteristics. CONCLUSIONS Detection on MR imaging improves the chances of curative resection of adenomas in Cushing disease. The evolution of MR imaging technology has improved the sensitivity for adenoma detection. Given the prognostic importance of MR imaging localization, further effort should be made to improve MR imaging protocols for Cushing disease.

Abstract
OBJECTIVE Superficial siderosis (SS) is a disabling neurodegenerative condition that may be caused by spinal dural defects. Surgical repair is increasingly performed, however clinical outcomes remain unclear. METHODS A systematic search of PubMed, MEDLINE, and EMBASE was conducted (inception to February 2020). Studies reporting cases of (i) superficial siderosis, (ii) spinal dural defect, (iii) and surgical closure of the defect were included. Demographic characteristics, clinical presentation, operative technique and clinical outcome were extracted for patient-level analysis. RESULTS A total of 26 publications were included, which reported 38 patients with a median age of 58 years, and a male predominance (78.9 %). Ataxia (85.7 %) and hearing loss (80.0 %) were the most common presenting symptoms. The causative dural defect was most commonly ventral in location (91.7 %) and most commonly identified by CT myelography (48.6 %). Operative technique was highly variable and included primary suture, fibrin glue, dural substitute, or tissue (fat or muscle) graft. Clinical improvement was reported in 21 %, with stabilisation of symptoms in the majority (66 %) and clinical deterioration in 13.2 %. Surgical complications were observed in 7.9 %. CONCLUSION In patients with superficial siderosis and spinal dural defect, operative closure leads to improvement or stabilisation of symptoms in the vast majority (87%) of patients.

Abstract
OBJECTIVE Incidental, asymptomatic pituitary adenomas require nuanced, shared decision-making, which is limited by a poor understanding of their natural history and effects on quality of life (QOL). A greater understanding of the effects of surgery would inform evidence-based care. METHODS A multicenter review of consecutive pituitary adenomas resected via an endoscopic endonasal approach (EEA) between late 2016 and mid-2021 was performed, with prospective, longitudinal QOL assessment (at 3 and 6 weeks and at 3, 6, and 12 months) postoperatively using the 35-item Anterior Skull Base Questionnaire. RESULTS Of 366 adenomas resected during the study period, 52 (14.2%) were incidentally discovered, of which 51 (98.1%) were macroadenomas. Preoperative QOL in patients with these incidentalomas was better than in those with adenomas presenting with endocrinopathy (p < 0.01), visual failure (p = 0.02), or headache (p = 0.03). Surgery was performed due to visual field deficits (13.5%, n = 7); ophthalmoplegia (1.9%, n = 1); radiological compression or contact of the optic apparatus (63.5%, n = 33); functional status (growth hormone-secreting tumor) (5.8%, n = 3); and clinically significant growth (15.4%, n = 8). Surgical outcomes were excellent, with vision improved in 100% (7/7) and complete resection in 84.6% (44/52). There were 2 (3.8%) cases of new cortisol deficiency, 3 (5.8%) cases of transient postoperative diabetes insipidus, and 4 (7.7%) cases of postoperative hyponatremia. There were no perioperative complications and no cases of postoperative CSF leakage. QOL transiently decreased during the first 3 weeks after surgery, then improved to above baseline levels by 3 months (p = 0.03) and continued to improve throughout the first postoperative year (p = 0.03). All surgical indications demonstrated an overall mean improvement in QOL at 3 months. QOL benefits were not affected by age or tumor size. CONCLUSIONS Resection of pituitary adenomas via the EEA provided a tangible benefit for patients within 3 months. Surgery via the EEA is safe, effective, and beneficial for patients with pituitary incidentalomas meeting accepted criteria for intervention.

Abstract
BACKGROUND Predicting extent of resection before pituitary surgery is imperative for operative planning and patient counseling. In the era of endoscopic endonasal transsphenoidal surgery (EEA), a specific, reliable tool for predicting resection of macroadenomas would have widespread applications. OBJECTIVE To identify factors that predict resection of pituitary macroadenomas through the EEA. METHODS A prospectively maintained, multicenter database of 277 consecutive macroadenomas resected through the EEA was analyzed. Multivariate logistic regression identified predictors of gross total resection (GTR). A simple scoring system, the Hardy, Age, Clival, Knosp, Depth (HACKD) Score, was developed and tested. RESULTS GTR was achieved in 82.3% (228/277) of cases. Older than 50 years (odds ratio [OR] 2.96, P = .01), clival extension (OR 5.87, P < .01), Hardy grade C or D suprasellar extension (OR 3.91, P = .01), Knosp grade 3 or 4 cavernous sinus invasion (OR 7.62, P < .01), and tumor depth >20 mm (OR 5.14, P < .01) were all associated with subtotal resection. The HACKD score, awarding 1 point each for Hardy grade C or D, and older than 50 years, and 2 points each for clival extension, Knosp grades 3 or 4, and tumor depth >20 mm, demonstrated excellent discriminative ability (AUROC 0.887, 95% CI: 0.839-0.934). The rate of GTR progressively decreased with a higher HACKD score. Rates of GTR were 95.8% (182/190) for low (HACKD ≤2), 59.5% (44/74) for moderate (HACKD 3-5), and 15.4% (2/13) for high (HACKD 6+) HACKD scores. CONCLUSION The HACKD score is a simple and accurate tool based on the largest study analyzing predictors of GTR in pituitary macroadenomas operated through the EEA.

Abstract
Patient quality of life (QOL) is an important metric of surgical success. To guide therapeutic advances in pituitary adenoma surgery, a validated, comprehensive instrument to quantify QOL is required. We aim to evaluate the validity of the 35 item anterior skull base questionnaire (ASBQ-35) in patients undergoing pituitary adenoma surgery. A total of 168 patients undergoing endoscopic resection of pituitary adenomas underwent longitudinal QOL assessment using the ASBQ-35 and the 22-item Sinonasal Outcomes Test (SNOT-22) over the first postoperative year. Validity of the ASBQ-35 was assessed by internal consistency, test-retest reliability, responsiveness to clinical change, and concurrent validity with the SNOT-22. Internal consistency of the ASBQ-35 was excellent, with a Cronbach's alpha > 0.95 across all timepoints. Test-retest reliability between 3 and 6 months (ICC = 0.82, p < 0.001) and 6 months and 12 months (ICC = 0.78, p < 0.001) was robust. Concurrent validity with SNOT-22 was strong across all timepoints (absolute Pearson r ≥ 0.63, p < 0.001). Mean ASBQ-35 scores were significantly worse at 3 weeks compared to preoperative baseline (mean difference - 0.28, p < 0.01); however, by 12 months, scores had significantly improved (mean difference + 0.24, p < 0.01), indicating that the scale is responsive to clinical change. Each of the 6 domains of the ASBQ, and all 35 component questions, contributed to the discriminative of the ASBQ to measure QOL during the first postoperative year. The ASBQ-35 is a valid, comprehensive tool for assessing QOL after endoscopic pituitary adenoma surgery. Each component of the ASBQ-35 contributed to the overall assessment of QOL during the first postoperative year.

Abstract
OBJECTIVE The relationship between lumbar disc herniation (LDH) size and the severity of preoperative pain and its impact on postoperative recovery is incompletely understood. This study was conducted to investigate the association between herniated disc fragment weight and pain before and after microdiscectomy. METHODS A consecutive series of patients from an ongoing randomised controlled trial (ACTRN12616001360404) were included in this study. Included patients were aged between 18 and 75, had a clinical diagnosis of radiculopathy, and MRI evidence of a concordant single-level lumbar disc herniation. All patients underwent standard microdiscectomy without aggressive discectomy or curettage of the endplates. Disc fragment weight was measured intraoperatively. RESULTS A total of 122 patients with a mean age of 49.5 ± 12.8 years, were included. The median weight of disc fragment was 0.545 g (95% CI 0.364 - 0.654 g). There was no relationship between disc weight and the duration of symptoms (p = 0.409) severity of preoperative leg pain (p = 0.070) or preoperative back pain (p = 0.884). Disc fragment weight was demonstrated to have no correlation with clinically significant postoperative leg pain improvement (p = 0.535) or back pain (p = 0.991). Additional LDH factors, including radiological percentage of canal compromise (p = 0.714), herniation classification (p = 0.462), and vertebral level (p = 0.788) were also shown to have no effect on leg pain outcomes. CONCLUSIONS Disc fragment weight had no effect on the severity of pain at presentation or after microdiscectomy. Patients benefit from surgery equally, regardless of the size of LDH.

Abstract
BACKGROUND Craniopharyngiomas are morbid tumors that significantly reduce patients' quality of life (QoL). The lifelong burden of endocrine, visual, hypothalamic, and limbic dysfunction can have disastrous consequences for the physical and psychosocial health of patients. Elucidating the factors that influence QoL could guide therapeutic interventions to improve patient well-being. METHODS A systematic review was performed in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement using the PubMed and Medline databases. Studies that had reported patient QoL using validated metrics in both adult and pediatric populations were included. Bias and methodological rigor were assessed using the MINORS (methodological index for nonrandomized studies) criteria. RESULTS A total of 25 studies, including 2025 patients, were available for review. Most studies were small, retrospective, cohort studies with a high risk of bias. The QoL of the patients with craniopharyngioma was lower than that of the general population. Hypothalamic involvement was consistently the strongest predictor of QoL. Endocrinopathy contributed to morbidity but could be ameliorated by hormone replacement therapy. Social and emotional dysregulation and a poor memory are common complaints after surgery, and iatrogenic damage to the infundibulum, hypothalamus, limbic system, and frontal lobes might underlie these concerns. Sleep-wake cycle dysfunction and hypothalamic obesity are serious consequences of hypothalamic damage. CONCLUSIONS An experienced multidisciplinary team is necessary to optimally manage the complex cases of these patients. The poor QoL of patients with craniopharyngioma is multifactorial. However, the contribution of iatrogenesis is not insubstantial. Improved surgical techniques, focusing on hypothalamic preservation, and adjuvant treatment options are required to improve the well-being of these patients.

Abstract
OBJECTIVE To establish the effect of endoscopic endonasal surgery (EES) on quality-of-life (QoL) in symptomatic Rathke cleft cyst (RCC). METHODS Analysis of 38 patients with RCC treated by EES, with regular overall (ASBQ-35) and sinonasal-specific (SNOT-22) QoL assessment during the first postoperative year. A systematic literature review of large case series was performed with pooled analysis. RESULTS In our series, mean age was 53.6 years with a female predominance (73.7%). Larger cysts were seen in males (p < 0.01), those with hypogonadism (p = 0.04), and visual dysfunction (p = 0.04). Complete normalisation of vision was seen in 83.3%. Persistence of visual dysfunction postoperatively was associated with diabetes (p = 0.005), hypertension (p = 0.02), suprasellar only location (p = 0.001), and monocular field cut (p = 0.02). Surgery did not significantly effect hormonal function. Sinonasal QoL transiently worsened after surgery, resolving within 3 weeks. A parallel transient worsening of overall QoL normalised by 6 weeks, and remained at preoperative baseline thereafter. These results were comparable to the literature, where 76.4% demonstrated improvement of vision and 13.1% had recurrence after treatment. There was no significant difference in outcomes between EES and microscopic approaches. CONCLUSIONS We report longitudinal QoL outcomes in RCC for the first time. Vision commonly improves with surgery, but endocrinopathy is likely to persist. Microvascular risk-factors may compromise visual improvement. Surgery causes a transient worsening of sinonasal symptoms that resolves within 3-6 weeks, but patients may not experience significant improvement in QoL within the first postoperative year.

Abstract
OBJECTIVE The objective of this study was to establish the effect of endoscopic endonasal surgery on longitudinal quality of life (QOL) in patients with anterior skull base meningioma. METHODS A prospectively collected cohort of consecutively operated anterior skull base meningiomas was analyzed. All cases were performed using the endoscopic endonasal approach (EEA). Sinonasal-specific and overall QOL were measured using the 22-Item Sinonasal Outcome Test and the Anterior Skull Base Questionnaire longitudinally (at 3 weeks, 6 weeks, and 3, 6, and 12 months) across the first postoperative year. The relationship between surgical and QOL outcomes to clinical and radiological characteristics was analyzed using multivariate regression. RESULTS Fifty cases were available, with a mean age of 61.5 years and female predominance (74.0%). Visual dysfunction and headache were the most common presenting symptoms, and tumors commonly took origin from the planum (46.0%), tuberculum (44.0%), and olfactory groove (24.0%). Median tumor volume was 4.6 cm3. Visual improvement was noted in 73.1% of cases with preoperative field deficits, while nonimprovement was associated with greater tumor height (p = 0.04). Gross-total resection was not possible in patients with 360° vessel encasement and high-grade cavernous sinus extension with ophthalmoplegia. Postoperative diabetes insipidus was observed only in cases with suprasellar extension. Sinonasal-specific QOL worsened transiently after surgery but returned to baseline levels after 3 weeks. Olfaction and taste scores returned to preoperative baseline scores within the year. Overall QOL at presentation was worse in those with larger tumors (p = 0.04) and visual failure (p = 0.04) and better in those presenting with headache (p = 0.04). Transient worsening of QOL was seen in the first 3 weeks, which returned to baseline by 6 weeks, and then improved to above preoperative levels at 6 months and beyond. Worse QOL at baseline (p = 0.01) and visual improvement (p = 0.01) predicted QOL improvement after surgery. CONCLUSIONS Longitudinal QOL in anterior skull base meningioma has been examined for the first time. Endoscopic endonasal surgery improves overall QOL after a transient 3-week worsening due to the sinonasal morbidity of the approach. Visual function is intimately tied to QOL, with worse vision associated with worse preoperative QOL, and QOL improving in parallel with visual restoration after surgery. The EEA is associated with better visual outcomes and should be the preferred approach in accessible tumors.

Abstract
BACKGROUND Patient-reported quality of life (QOL) is a vital metric for surgical success. OBJECTIVE To assess the effect of surgery on QOL in the largest prospectively collected, longitudinal cohort of surgically managed pituitary adenomas. METHODS A consecutive surgical adenoma cohort (n = 304) between late 2016 and mid-2020 underwent a scheduled overall (Anterior Skull Base Questionnaire-35) and sinonasal-specific (Sinonasal Outcome Test-22) QOL assessment. Scores were stratified by adenoma subtype and analyzed for clinical predictors of QOL changes. RESULTS The average age was 53.8 ± 16 yr, and 53% of participants were female. 60.9% of adenomas were nonfunctioning while adrenocorticotropic hormone adenomas (16.4%), growth hormone adenomas (14.1%), and prolactinomas (5.9%) were the most prevalent secreting adenomas. Baseline overall QOL differed between tumor types (P = .006), with adrenocorticotropic hormone adenomas worse than growth hormone adenomas (P = .03) and nonfunctioning pituitary adenomas (NFPA) (P < .001). Sinonasal QOL worsened in the 3 wk after surgery but returned to baseline by 6 wk and beyond. Overall QOL worsened at 3 wk after surgery (P < .001) but significantly improved from baseline by 3 mo (P = .009) and beyond (P < .001). Emotional functioning improved soon after surgery, followed by performance and pain, and then, by 6 mo, physical function and vitality. Predictors of improved QOL were sellar/suprasellar lesions (P = .01), prolactinomas (P = .003), and NFPA (P = .04). Conversely, new postoperative hypopituitarism (P = .04) and larger adenoma volume (P = .04) predicted QOL worsening. CONCLUSION QOL is worsened after surgery at early time points. Prolactinomas and NFPA enjoy significant QOL improvements from surgery as early as 3 mo postoperatively. Other functional tumors may experience early benefits in younger patients without hypopituitarism and when isolated to the sellar/suprasellar region. These findings provide valuable information for counseling patients and setting expectations for surgery.

Abstract
INTRODUCTION Frailty is a state of physiological vulnerability that negatively influences surgical outcomes. The effect of frailty on pituitary adenoma surgery, however, is not clear, and patients may be wrongly denied surgery because they are "too frail". We examined the effects of frailty on surgical outcome and quality-of-life (QoL) in patients undergoing endoscopic transsphenoidal resection of pituitary adenomas. METHODS A prospective, consecutive cohort of surgically managed pituitary adenoma was analysed. Frailty was defined by the 5-factor modified Frailty Index (mFI-5) and the Charlson Comorbidity Index (CCI). QoL was measured by the anterior skull base questionnaire (ASBQ) and sinonasal outcomes test (SNOT). RESULTS Of 304 patients with pituitary adenomas, 42 (13.8%) were frail (mFI5 of > 1). Frail patients tended to have smaller adenomas (p < 0.0001) with less suprasellar extension (p < 0.0001). Both overall (ASBQ) and sinonasal-specific (SNOT) QoL were not affected by frailty on multivariate analysis. Endocrine and visual outcomes were similarly not worsened by frailty. Overall, medical complications were uncommon, and perioperative morbidity or mortality was not significantly greater in the frail group. CONCLUSION Frail patients experience the same QoL benefits from surgery as their non-frail counterparts, and have equivalently successful visual and endocrine outcomes. Frailty should not be seen as a barrier to successful surgical management of pituitary adenomas.

Abstract
OBJECTIVE To identify risk factors for the development of postoperative diabetes insipidus (DI) in a modern cohort of endoscopic endonasal transsphenoidal surgery. METHODS Analysis of prospectively collected data of 449 consecutive patients operated on for anterior skull base pathology. DI was defined as a polyuria (> 250 ml/h for ≥ 2 consecutive hours) polydipsia syndrome associated with hypotonic urine with or without hypernatraemia. Multivariate logistic regression was used to identify predictors of postoperative DI. A simple scoring system was then created. RESULTS Postoperative DI occurred in 46 (10.2%) patients. The development of DI did not affect quality of life. Predictors of DI on multivariate analysis included suprasellar extension (OR 2.2; p = 0.04), age < 50 years (OR 2.8; p = 0.003), craniopharyngioma histology (OR 6.7; p = 0.002), and Kelly grade 3 intraoperative CSF leak (OR 2.1; p = 0.04). The SALT score was created based on these characteristics, with one point awarded for each feature present, and predicted DI with fair to good predictive value in our cohort (AUROC 0.735 (95%CI 0.65-0.82)). The rates of postoperative DI were 4.0%, 6.5%, 15.0%. 36.8% and 85.7% for SALT scores of zero, one, two, three, and four, respectively. CONCLUSIONS The SALT score predicts postoperative DI with fair to good accuracy, and now requires prospective external validation. Improved prediction of DI could optimize resource allocation and facilitate individualised preoperative patient counselling. We also provide our algorithm for diagnosis and treatment of DI.

Abstract
Knowledge of anatomy and its variations is the key to safe and efficient surgery. The endoscopic endonasal route to the sella has evolved to become the preferred route to access a wide variety of diseases. We describe the skeletal, vascular, and neural anatomic variations that could be encountered from the nasal phase, through the sphenoid phase, to the sellar phase of the operative exposure. A preoperative checklist is also provided.

Abstract
A local sphenoid mucosal flap (SMF) is naturally raised during endonasal exposure of the sella. Typically, these flaps are repositioned; however, they could be used in place of a nasoseptal flap (NSF) for closure of low-grade CSF leaks. In this study, we aim to establish the safety and efficacy of SMF closure for low-grade CSF leaks and to assess the impact on sinonasal quality of life (QoL) compared to NSF closure. In a consecutive, prospective cohort of anterior skull base pathology, data regarding sellar and suprasellar extension (Hardy grade), cavernous sinus invasion (Knosp grade), intraoperative (Kelly grade) and postoperative CSF leak, and sino-nasal QoL data (SNOT-22) were analysed. Of 187 patients with no/low flow (Kelly 0-1) intraoperative CSF leak, 127 (67.9%) received a SMF and 60 (32.1%) received a NSF. A total of 141/187 (75.4%) had no intraoperative leak, while 46/187 (24.6%) had grade-1 leaks. SMF were used in 70.9% (100/141) of cases without intraoperative leak, and 58.7% (27/46) of cases with Kelly grade-1 leaks. Hardy grade 4, grade E and Knosp grade 4 lesions were all more commonly closed with a NSF (p < 0.05). Two patients (1.1%) had postoperative CSF leaks, both in the SMF group, and both after no discernible intraoperative leak. Sinonasal QoL was below baseline for up to 3 months postoperatively. SMF cases tended to have better sinonasal QoL for up to 6 weeks after surgery. Thus, in the largest cohort to date, SMF are a safe alternative to NSF for closure low-grade skull base defects. Sinonasal QoL was better in the first 6 weeks after SMF closure than NSF closure.

Abstract
Disorders of tonicity, hyponatraemia and hypernatraemia, are common in neurosurgical patients. Tonicity is sensed by the circumventricular organs while the volume state is sensed by the kidney and peripheral baroreceptors; these two signals are integrated in the hypothalamus. Volume is maintained through the renin-angiotensin-aldosterone axis, while tonicity is defended by arginine vasopressin (antidiuretic hormone) and the thirst response. Edelman found that plasma sodium is dependent on the exchangeable sodium, potassium and free-water in the body. Thus, changes in tonicity must be due to disproportionate flux of these species in and out of the body. Sodium concentration may be measured by flame photometry and indirect, or direct, ion-sensitive electrodes. Only the latter method is not affected by changes in plasma composition. Classification of hyponatraemia by the volume state is imprecise. We compare the tonicity of the urine, given by the sodium potassium sum, to that of the plasma to determine the renal response to the dysnatraemia. We may then assess the activity of the renin-angiotensin-aldosterone axis using urinary sodium and fractional excretion of sodium, urate or urea. Together, with clinical context, these help us determine the aetiology of the dysnatraemia. Symptomatic individuals and those with intracranial catastrophes require prompt treatment and vigilant monitoring. Otherwise, in the absence of hypovolaemia, free-water restriction and correction of any reversible causes should be the mainstay of treatment for hyponatraemia. Hypernatraemia should be corrected with free-water, and concurrent disorders of volume should be addressed. Monitoring for overcorrection of hyponatraemia is necessary to avoid osmotic demyelination.

Abstract
Pyramidal weakness, that is, the weakness that preferentially spares the antigravity muscles, is considered an integral part of the upper motor neuron syndrome. Despite its name, pyramidal weakness has very little to do with the pyramidal tract, and preeminent texts on neurology, neuroanatomy, and clinical examination differ considerably in their descriptions and localization of this enigmatic finding. Evidence from human and nonhuman primate studies demonstrates that lesions confined only to the corticospinal (pyramidal) tract cause significant deficits in fine motor control of the hand, but do not cause posturing or patterned weakness of the extremities. Lesioning of the corticofugal fibers, particularly the corticoreticular and corticopontine tracts, leads to dysbalanced output from reticulospinal, and vestibulospinal systems, which along with changes in rubrospinal tract output balance, probably accounts for the pyramidal weakness pattern. Importantly, this would delineate that pyramidal weakness could only be incited by lesions above the brainstem. It has also been suggested that the inherently greater strength of the antigravity musculature is the substrate for pyramidal weakness, independent of any preferential motor innervation. These hypotheses require further testing in myometric studies with carefully selected participants.

Abstract
Treatment of unruptured intracranial aneurysms can reduce the risk of subarachnoid hemorrhage and its associated morbidity and mortality. However, current methods to predict the risk of rupture and optimize treatment strategies for intracranial aneurysms are limited. Assessment of intra-aneurysmal flow using 4-dimensional magnetic resonance imaging (4D MRI) is a novel tool that could be used to guide therapy. A systematic search of the literature was performed to provide a state-of-the-art review on 4D MRI assessment of unruptured intracranial aneurysms. A total of 18 studies were available for review. Eccentric flow on 4D MRI is associated with a greater aspect ratio and peak wall shear stress (WSS). WSS, vorticity, and peak velocity are greater in saccular than fusiform aneurysms. Unstable aneurysms are associated with greater WSS, peak wall stress, and flow jet angle and may exhibit wall enhancement. In comparison to computational fluid dynamics (CFD), 4D MRI has a lower spatial resolution and reports lower WSS and velocity magnitudes, but these parameters equalize when spatial resolution is matched. 4D MRI demonstrates the intra-aneurysmal hemodynamic changes associated with flow diversion, including significantly decreased flow velocity. Thus, 4D MRI is a novel, noninvasive imaging tool used for the evaluation of hemodynamics within intracranial aneurysms. Hemodynamic indices derived from 4D MRI appear to correlate well with the simulated (CFD) values and may be used to measure the success of endovascular therapies and risk factors for aneurysm growth and rupture.

Abstract
BACKGROUND Tension pneumocephalus (TP) is a rare but feared complication of endoscopic endonasal skull base surgery. In contrast to simple pneumocephalus, which is common after endoscopic transnasal approaches and managed conservatively, TP represents a neurosurgical emergency and mandates urgent decompression. CASE DESCRIPTION Here we present 2 cases of TP as a consequence of positive pressure ventilation following endoscopic endonasal skull base surgery. Both occurred during resuscitation for postoperative hypoxia. These cases prompted the development of an institution-wide protocol to identify and manage patients at risk of TP after extended skull base approaches. CONCLUSIONS To our knowledge, these are the only such cases of postoperative TP following positive pressure ventilation in the literature.

Abstract
BACKGROUND The endoscopic endonasal approach to the skull base avoids some of the surgical morbidity associated with a transcranial approach, however it often results in large skull-base defects requiring secure closure. The nasoseptal flap has become the preferred method for closure of such defects but may be associated with its own morbidity. METHODS A consecutive cohort of patients with skull base pathology with prospectively collected quality of life data using ASBQ and SNOT was analysed. They were grouped into those who received a nasoseptal flap and those who did not. Pre-operative total ASBQ and SNOT scores, and their individual components, were compared to data collected at days 1, 3, and 7; six-weeks; and 3, 6, and 12-months postoperatively. RESULTS Of 158 patients available for analysis, nasoseptal flaps were performed in 52 (33%). Average follow-up (±standard deviation) was 8.1 ± 3.9 months for ASBQ data and 8.2 ± 3.8 months for SNOT data. In the first post-operative week, nasal symptoms and otalgia were worse in the flap group. At six-weeks and beyond, there was no difference between groups in overall ASBQ or SNOT scores, or in the rate of clinically-significant improvement in SNOT or ASBQ scores or their components. CONCLUSION In the largest cohort of patients to date, the use of a nasoseptal flap is associated with nasal symptoms and otalgia in the acute post-operative period, but is not associated with any long-term detriment to quality of life after endoscopic skull base surgery.

Abstract
Intraoperative localization in spinal surgery is essential to facilitate the best surgical outcome and to avoid wrong-site surgery. Intraoperative fluoroscopy is generally adequate, but anatomical variation, body habitus, and the inherent difficulties of fluoroscopy at certain levels may lead the surgeon astray. Here, the authors present their technique for preoperative localization that relies solely on fixed anatomical landmarks using CT-guided, percutaneously placed radiopaque markers. In the outpatient setting, low-dose CT scanning of the neuraxis is performed to identify fixed landmarks and, under local anesthesia and CT guidance, a pushable microcoil is inserted through a Chiba needle into the periosteum of the pedicle at the level of interest. The patient returns home with no precautions while the coil is in situ, and then the patient returns sometime later for surgery. Intraoperatively, typically a single lateral radiograph is required to visualize the coil and the level. Preoperative placement of radiopaque markers at the level of interest is an effective tool for avoiding wrong-site surgery, especially in circumstances in which fluoroscopy may be troublesome. The authors' method is accurate, effective, and expeditious and can be performed easily in the outpatient setting.

Abstract
PURPOSE The pituitary gland is an unusual site for metastatic spread, but as patients with metastatic malignancy are living longer, it may become more prevalent. Compression of important anatomy adjacent to the sella may produce disabling symptoms and endocrine derangement, leading to significant morbidity. METHODS An ambispective review of patient records between 2013 and 2017 from three neurosurgical centres was performed. After identifying cases, further investigation was performed to evaluate patient demographic, symptoms at presentation, radiological and histological findings, management, and outcome. RESULTS Our investigation identified 12 patients with pituitary metastasis. The average age of the cases was 63.4 years, with breast (n = 4) and lung (n = 4) being the most common primary cancers. In half the cases there was a history of metastatic disease, while in one-quarter of cases, pituitary symptoms were the first sign of malignancy. Adenohypophyseal dysfunction (83%), diabetes insipidus (DI) (75%), headache (67%) and visual field defects (67%) were the most common findings at presentation. Glucocorticoid replacement increased the sensitivity for diagnosis of DI. All cases were contrast enhancing on MRI and the endoscopic trans-sphenoidal approach was preferred for biopsy and debulking. CONCLUSIONS The pituitary should not be overlooked as a site of metastasis and sellar symptoms may be the first presentation of neoplastic disease. Any biochemical or clinical sign of pituitary pathology in a patient with known cancer should raise suspicion for sellar metastasis. Moreover, the development of DI or ophthalmoplegia from any pituitary lesion is suggestive of metastatic disease even in patients with no known primary.
