OBJECTIVEThe authors previously described a graded approach to skull base repair following endonasal microscopic or endoscope-assisted tumor surgery. In this paper they review their experience with skull base reconstruction in the endoscopic era.METHODSA retrospective review of a single-institution endonasal endoscopic patient database (April 2010–April 2017) was undertaken. Intraoperative CSF leaks were graded based on size (grade 0 [no leak], 1, 2, or 3), and repair technique was documented across grades. The series was divided into 2 epochs based on implementation of a strict perioperative antibiotic protocol and more liberal use of permanent and/or temporary buttresses; repair failure rates and postoperative meningitis rates were assessed for the 2 epochs and compared.RESULTSIn total, 551 operations were performed in 509 patients for parasellar pathology, including pituitary adenoma (66%), Rathke’s cleft cyst (7%), meningioma (6%), craniopharyngioma (4%), and other (17%). Extended approaches were used in 41% of cases. There were 9 postoperative CSF leaks (1.6%) and 6 cases of meningitis (1.1%). Postoperative leak rates for all 551 operations by grade 0, 1, 2, and 3 were 0%, 1.9%, 3.1%, and 4.8%, respectively. Fat grafts were used in 33%, 84%, 97%, and 100% of grade 0, 1, 2, and 3 leaks, respectively. Pedicled mucosal flaps (78 total) were used in 2.6% of grade 0–2 leaks (combined) and 79.5% of grade 3 leaks (60 nasoseptal and 6 middle turbinate flaps). Nasoseptal flap usage was highest for craniopharyngioma operations (80%) and lowest for pituitary adenoma operations (2%). Two (3%) nasoseptal flaps failed. Contributing factors for the 9 repair failures were BMI ≥ 30 (7/9), lack of buttress (4/9), grade 3 leak (4/9), and postoperative vomiting (4/9). Comparison of the epochs showed that grade 1–3 repair failures decreased from 6/143 (4.1%) to 3/141 (2.1%) and grade 1–3 meningitis rates decreased from 5 (3.5%) to 1 (0.7%) (p = 0.08). Prophylactic lumbar CSF drainage was used in only 4 cases (< 1%), was associated with a higher meningitis rate in grades 1–3 (25% vs 2%), and was discontinued in 2012. Comparison of the 2 epochs showed increase buttress use in the second, with use of a permanent buttress in grade 1 and 3 leaks increasing from 13% to 55% and 32% to 76%, respectively (p < 0.001), and use of autologous septal/keel bone as a permanent buttress in grade 1, 2, and 3 leaks increasing from 15% to 51% (p < 0.001).CONCLUSIONSA graded approach to skull base repair after endonasal surgery remains valid in the endoscopic era. However, the technique has evolved significantly, with further reduction of postoperative CSF leak rates. These data suggest that buttresses are beneficial for repair of most grade 1 and 2 leaks and all grade 3 leaks. Similarly, pedicled flaps appear advantageous for grade 3 leaks, while CSF diversion may be unnecessary and a risk factor for meningitis. High BMI should prompt an aggressive multilayered repair strategy. Achieving repair failure and meningitis rates lower than 1% is a reasonable goal in endoscopic skull base tumor surgery.

Abstract Background The endoscopic endonasal approach (EEA) has become increasingly used for resection of skull base tumors in the sellar and suprasellar regions. A nasoseptal flap (NSF) is routinely used for anterior skull base reconstruction; however, there are numerous additional allografts and autografts being used in conjunction with the NSF. The role of perioperative cerebrospinal fluid (CSF) diversion is also unclear. Objective This study was aimed to analyze success of high-flow CSF leak repair during EEA procedures without use of CSF diversion through lumbar drainage. Methods A retrospective chart review of patients who had intraoperative high-flow CSF leak during EEA procedures at our institution between January 2013 and December 2017 was performed. CSF leaks were repaired with use of a fascia lata button graft and nasoseptal flap, without use of perioperative lumbar drains. Results A total of 38 patients were identified (10 male, 28 female). Patient BMIs ranged from 19.7 to 49 kg/m2 (median = 31 kg/m2), with 18 patients meeting criteria for obesity (BMI > 30 kg/m2) and 12 patients overweight (25 kg/m2 < BMI < 29.9 kg/m2). There was no incidence of postoperative CSF leak. Conclusion In our experience, the nasoseptal flap used in conjunction with the fascia lata button graft is a safe, effective and robust combination for cranial base reconstruction with high-flow intraoperative CSF leaks, without need for lumbar drains.

Rate Analysis

Introduction Post-operative CSF leak still represents the main drawback of Endoscopic Endonasal Approach (EEA), and different reconstructive strategies have been proposed in order to decrease its rate. Objective To critically analyze the effectiveness of different adopted reconstruction strategies in patients that underwent EEA. Materials and methods Adult patients with skull base tumor surgically treated with EEA were retrospectively analyzed. Data recorded for each case concerned patient demographics, type of surgical approach, histotype, anatomical site of surgical approach, intra-operative CSF leak grade (no leak (INL), low flow (ILFL), high flow (IHFL)), reconstructive adopted strategy, Lumbar Drain positioning, post-operative CSF leak rate and intra/post-operative complications. Results A total number of 521 patients (January 2012-December 2019) was included. Intra-operative CSF leak grade showed to be associated with post-operative CSF leak rate. In particular, the risk to observe a post-operative CSF leak was higher when IHFL was encountered (25,5%; Exp(B) 16.25). In particular, vascularized multilayered reconstruction and fat use showed to be effective in lowering post-operative CSF leaks in IHFL (p 0.02). No differences were found considering INL and ILFL groups. Yearly post-operative CSF leak rate analysis showed a significative decreasing trend. Conclusion Intra-operative CSF leak grade strongly affected post-operative CSF leak rate. Multilayer reconstruction with fat and naso-septal flap could reduce the rate of CSF leak in high risk patients. Reconstructive strategies should be tailored according also to the type and the anatomical site of the approach.

Pilocytic Astrocytomas

Abstract Backgrounds Pilocytic astrocytomas (PAs) are World Health Organization (WHO) grade I tumors, which are relatively common, and are benign lesions in children. PAs could originate from the cerebellum, optic pathways, and third ventricular/hypothalamic region. Traditional various transcranial routes are used for hypothalamic PAs (HPAs). However, there are few studies on hypothalamic PAs treated through the endoscopic endonasal approach (EEA). This study reports the preliminary experience of the investigators and results with HPAs via expanded EEAs. Methods All patients with HPAs, undergone EEA in our hospital from 2017 to 2019, were retrospectively reviewed. The demographic data, clinical symptoms, complications, skull base reconstruction, prognosis, and endocrinological data were all recorded and analyzed in detail. Results Finally, five female patients were enrolled. The average age of patients was 28.6 ± 14.0. All patients had complaints about their menstrual disorder. One patient had severe bilateral visual impairment. Furthermore, only one patient suffered from severe headache due to acute hydrocephalus, although there were four patients with headache or dizziness. Four cases achieved gross-total resection, and one patient achieved subtotal resection. Furthermore, there was visual improvement in one patient (case 5), and postoperative worsening of vision in one patient (case 4). However, only one patient had postoperative intracranial infection. None of the patients experienced a postoperative CSF leak, and in situ bone flap (ISBF) techniques were used for two cases for skull base repair. In particular, ISBF combined with free middle turbinate mucosal flap was used for case 5. After three years of follow-up, three patients are still alive, two patients had no neurological or visual symptoms, or tumor recurrence, and one patient had severe hypothalamic dysfunction. Unfortunately, one patient died of severe postoperative hypothalamus reaction, which presented with coma, high fever, diabetes insipidus, hypernatremia and intracranial infection. The other patient died of recurrent severe pancreatitis at one year after the operation. Conclusion Although the data is still very limited and preliminary, EEA provides a direct approach to HPAs with acceptable prognosis in terms of tumor resection, endocrinological and visual outcomes. ISBF technique is safe and reliable for skull base reconstruction.

Abstract BACKGROUND Proper skull base reconstruction after endoscopic endonasal pituitary surgery is of great importance to decrease the rate of complications. OBJECTIVE To assess the safety and efficacy of reconstruction with materials other than fat graft and naso-septal flaps (NSF) to avoid their associated morbidities. METHODS The authors’ institutional database for patients who underwent endoscopic endonasal approach for pituitary adenoma was reviewed. Exclusion criteria included recurrence, postradiation therapy, and reconstruction by fat graft or NSF. They were divided into group A, where collagen matrix (CM) (DuraGen® Plus Matrix, Integra LifeSciences Corporation, Plainsboro, New Jersey) alone was used; group B, where CM and simple mucoperiosteum graft were used and group C, which included cases without CM utilization. RESULTS The study included 252 patients. No age, gender, or body mass index statistically significant difference between groups. Group B included the largest tumor size (23.0 mm) in comparison to groups A (18.0 mm) and C (13.0 mm). Suprasellar extension was more frequently present (49.4%) in comparison to groups A (29.8%, P = .001) and C (21.2%, P &lt; .001). Postoperative cerebrospinal fluid (CSF) leak rate was 0%, 2.9%, and 6% in groups A, B, and C, respectively. In group B, the CSF leak rate decreased from 45.9% intraoperatively to 2.9% postoperatively (P &lt; .001). In group A, the CSF leak reduction rate was almost statistically significant (P = .06). CONCLUSION Utilization of CM and simple mucosperiosteal graft in skull base reconstruction following pituitary adenoma surgery is an effective method to avoid the morbidities associated with NSF or fat graft.

The Impact

OBJECTIVES: Reconstruction following endoscopic skull base surgery requires a high degree of success to avoid the morbidity of postoperative cerebrospinal fluid (CSF) leak. The impact on outcomes of CSF visualization with intrathecal fluorescein, however, is unknown. STUDY DESIGN: A retrospective review of patients undergoing endoscopic skull base surgery with intrathecal fluorescein. A possible correlation between intraoperative fluorescein identification and postoperative CSF leak was analyzed. RESULTS: 61 patients underwent surgery for a variety of lesions including pituitary adenoma (55.7%), encephalocele (14.8%), and meningioma (9.8%). Seven (19.4%) of the 37 patients with intraoperative fluorescein leak experienced postoperative CSF leak compared to 0 of the 24 patients who did not have intraoperative fluorescein leak ( P = 0.02). All cases of CSF leak resolved with lumbar drainage alone. CONCLUSIONS: The lack of intraoperative fluorescein leak-age correlates strongly with a low risk for postoperative CSF leak. This can be used to stratify the extent of skull base reconstruction required during endoscopic skull base surgeries.

Abstract Introduction Anterior skull base cerebrospinal fluid (CSF) leaks are managed successfully with endonasal surgery. Endoscopic closure of CSF leaks from posterior table of the frontal sinus remains challenging. Vascularized Hadad-Bassagasteguy flap (HBF) reconstruction of the skull base has increased CSF closure rates but does not extend to frontal sinus. We describe our technique using septal flap pedicled by anterior ethmoid artery (AEA) for repairing frontal defects. Method Retrospective review of cases of frontal CSF leak repair using the AEA flap reconstruction. Flap design: an anterior vertical septal mucosa incision at posterior border of the frontal sinusotomy is made and extended to nasal floor. Posterior vertical incision is made 1 cm posterior to the projection of the axilla of the middle turbinate on the septum and extended to nasal floor. A horizontal incision along the nasal floor joins the two incisions. The flap is raised and rotated into the frontal sinus over the posterior table reconstructed defect. Results Three patients identified. Two males, one female, aged 11, 33 and 56. Patient histories included recurrent bacterial meningitis following head trauma, recurrent sinusitis and fronto-ethmoidal osteoma, with intraoperative CSF leak and CSF rhinorrhea due to meningoencephalocele. The three posterior wall defects were successfully repaired endoscopically with multilayer reconstruction and the AEA septal flap. Conclusions The anterior ethmoid artery septal flap can be successfully utilised for frontal CSF leak repair. Flap is conveniently located for frontal sinus defects. When the septum is intact it provides an excellent final layer as part of multilayer reconstruction.

Abstract Objectives A variety of endonasal sellar repair techniques have been described; many are complex, multilayered, and carry potential morbidity. We propose an effective, technically simple single-layer repair for select sellar defects, including those with an intraoperative cerebrospinal fluid (CSF) leak. Our technique utilizes only a synthetic dural substitute inlay and dural sealant glue without packing or lumbar drainage. Design This is a retrospective review-based study. Setting This study was conducted at tertiary care center. Participants Patients who underwent endoscopic transsphenoidal surgery for pituitary adenoma and sellar reconstruction with the aforementioned inlay technique. Patients were selected for this technique if they had an identified intraoperative CSF leak, a patulous diaphragm (expanded and thinned diaphragma sella), or a comorbidity excluding them from a simpler onlay only reconstruction. Outcome Measures Postoperative CSF leak and sinonasal morbidity included in the study Results A total of 409 subjects were identified; 368 were initial resections. Gross total resection of the pituitary adenoma was achieved in 356 (87.0%) cases. Average tumor size was 2.6 ± 1.1 cm. Average tumor volume was 10.8 ± 12.1 cm3. There were 135 intraoperative CSF leaks and 196 patulous diaphragms. There were five postoperative CSF leaks (1.2%), all of which occurred in the first half of our series. Pre- and postoperative sino-nasal outcomes test-22 scores were 19.2 ± 18.2 and 18.8 ± 21.3 (p = 0.492), respectively. Conclusion A synthetic dural substitute inlay and dural sealant glue is an excellent single-layer repair for sellar defects, even those with an intraoperative CSF leak. This technique is highly effective in preventing postoperative CSF leaks and does not utilize packing or lumbar drainage. It also avoids the potential cost and morbidity associated with more complex and multilayered closures.

Background Pediatric pituitary adenoma is a rare skull base neoplasm, accounting for 3% of all intracranial neoplasms in children and 5% of pituitary adenomas. Compared with pituitary tumors in adults, secreting tumors predominate and longer disease trajectories are expected due to the patient age resulting in a natural history and treatment paradigm that is complex and controversial. Objectives The aims of this study were to describe a large, single-institution series of pediatric pituitary adenomas with extensive long-term follow-up and to conduct a systematic review examining outcomes after pituitary adenoma surgery in the pediatric population. Methods The study cohort was compiled by searching institutional pathology and operative reports using diagnosis and site codes for pituitary and sellar pathology, from 1956 to 2016. Systematic review of the English language literature since 1970 was conducted using PubMed, MEDLINE, Embase, and Google Scholar. Results Thirty-nine surgically managed pediatric pituitary adenomas were identified, including 15 prolactinomas, 14 corticotrophs, 7 somatotrophs, and 4 non-secreting adenomas. All patients underwent transsphenoidal resection (TSR) as the initial surgical treatment. Surgical cure was achieved in 18 (46%); 21 experienced recurrent/persistent disease, with secondary treatments including repeat surgery in 10, radiation in 14, adjuvant pharmacotherapy in 11, and bilateral adrenalectomy in 3. At the last follow-up (median 87 months, range 3–581), nine remained with recurrent/persistent disease (23%).Thirty-seven publications reporting surgical series of pediatric pituitary adenomas were included, containing 1,284 patients. Adrenocorticotropic hormone (ACTH)-secreting tumors were most prevalent (43%), followed by prolactin (PRL)-secreting (37%), growth hormone (GH)-secreting (12%), and nonsecreting (7%). Surgical cure was reported in 65%. Complications included pituitary insufficiency (23%), permanent visual dysfunction (6%), chronic diabetes insipidus (DI) (3%), and postoperative cerebrospinal fluid (CSF) leak (4%). Mean follow-up was 63 months (range 0–240), with recurrent/persistent disease reported in 18% at the time of last follow-up. Conclusion Pediatric pituitary adenomas are diverse and challenging tumors with complexities far beyond those encountered in the management of routine adult pituitary disease, including nuanced decision-making, a technically demanding operative environment, high propensity for recurrence, and the potentially serious consequences of hypopituitarism with respect to fertility and growth potential in a pediatric population. Optimal treatment requires a high degree of individualization, and patients are most likely to benefit from consolidated, multidisciplinary care in highly experienced centers.
