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.

Abstract Objectives A variety of endonasal sellar repair techniques have been described; many of which are complex, expensive, and carry potential morbidity but are felt to be necessary to prevent postoperative cerebrospinal fluid (CSF) leaks. We propose an effective, technically simple repair for select sellar defects utilizing an onlay of regenerated oxidized cellulose. Design Retrospective review of patients from a single neurosurgeon who underwent endoscopic transsphenoidal surgery for pituitary adenoma and sellar reconstruction with only an onlay of regenerated oxidized cellulose. Patients were selected for this repair technique based on the absence of: (1) intraoperative identification of a CSF leak, (2) patulous diaphragm (expanded diaphragm sella herniating to or through sellar floor defect), and (3) other prohibiting comorbidities. Setting The present study was conducted at a tertiary care center. Participants In this study, pituitary adenoma patients were the participants. Outcome Measures Main outcome measure of the study is postoperative CSF leak. Results A total of 172 patients were identified. Of these, 153 were initial resections of pituitary adenomas. Gross total resection was achieved in 142 (82.6%) cases. Average tumor size was 2.2 ± 1.1 cm. Average tumor volume was 10.4 ± 19.8 cm3. No patients had intraoperative CSF leaks. All cases were repaired with only an onlay of regenerated oxidized cellulose. There were two postoperative CSF leaks (1.16%). Pre and postoperative SNOT-22 scores were 12.9 ± 11.9 and 14.3 ± 14.9 (p = 0.796), respectively. Conclusion The use of an onlay of regenerated oxidized cellulose alone is an effective repair technique for select sellar defects. This technique does not result in increased postoperative CSF leak rates and avoids the higher relative cost and potential morbidity associated with more complex, multilayered closures.

Postoperative cerebrospinal fluid (CSF) leaks still occur in patients without intraoperative CSF leaks after endoscopic endonasal pituitary adenoma surgery. We propose a reconstructive technique, the sellar floor flap (SFF), for universal sellar anatomical reconstruction. A total of 113 patients without intraoperative CSF leaks after endoscopic endonasal pituitary adenoma surgery from July 2013 to June 2016 were reviewed: 43 underwent sellar reconstruction with the SFF (the SFF group) and 70 underwent sellar packing only (the nonreconstruction group). No case of postoperative CSF leak was reported in the SFF group, whereas 7 cases were reported in the nonreconstruction group ( P < .05). The SFF is suitable for universal reconstruction after endoscopic endonasal pituitary adenoma surgery and may decrease postoperative CSF leak.

OBJECTIVECerebrospinal fluid (CSF) rhinorrhea is among the most common complications following transsphenoidal surgery for sellar region lesions. The aim of this study was to review the authors’ institutional experience in identifying, repairing, and treating CSF leaks associated with direct endonasal transsphenoidal operations.METHODSThe authors performed a retrospective review of cases involving surgical treatment of pituitary adenomas and other sellar lesions at the University of Southern California between December 1995 and March 2016. Inclusion criteria included all pathology of the sellar region approached via a direct microscopic or endoscopic endonasal transsphenoidal approach. Demographics, pathology, intraoperative and postoperative CSF leak rates, and other complications were recorded and analyzed. A literature review of the incidence of CSF leaks associated with the direct endonasal transsphenoidal approach to pituitary lesions was conducted.RESULTSA total of 1002 patients met the inclusion criteria and their cases were subsequently analyzed. Preoperative diagnoses included pituitary adenomas in 855 cases (85.4%), Rathke’s cleft cyst in 94 (9.4%), and other sellar lesions in 53 (5.2%). Lesions with a diameter ≥ 1 cm made up 49% of the series. Intraoperative repair of an identified CSF leak was performed in 375 cases (37.4%) using autologous fat, fascia, or both. An additional 92 patients (9.2%) underwent empirical sellar reconstruction without evidence of an intraoperative CSF leak. Postoperative CSF leaks developed in 26 patients (2.6%), including 13 (1.3% of the overall group) in whom no intraoperative leak was identified. Among the 26 patients who developed a postoperative CSF leak, 13 were noted to have intraoperative leak and underwent sellar repair while the remaining 13 did not have an intraoperative leak or sellar repair. No patients who underwent empirical sellar repair without an intraoperative leak developed a postoperative leak. Eight patients underwent additional surgery (0.8% reoperation rate) for CSF leak repair, and 18 were successfully treated with lumbar drainage or lumbar puncture alone. The incidence of postoperative CSF rhinorrhea in this series was compared with that in 11 other reported series that met inclusion criteria, with incidence rates ranging between 0.6% and 12.1%.CONCLUSIONSIn this large series, half of the patients who developed postoperative CSF rhinorrhea had no evidence of intraoperative CSF leakage. Unidentified intraoperative CSF leaks and/or delayed development of CSF fistulas are equally important sources of postoperative CSF rhinorrhea as the lack of employing effective CSF leak repair methods. Empirical sellar reconstruction in the absence of an intraoperative CSF leak may be of benefit following resection of large tumors, especially if the arachnoid is thinned out and herniates into the sella.

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.

Objective: Diagnosis of cerebrospinal fluid (CSF) leaks is sometimes challenging in the postoperative period following pituitary and ventral skull base surgery. Intrathecal fluorescein (ITF) may be useful in this setting. Design: Retrospective chart review Setting: Tertiary care center Methods and Participants: All patients who underwent pituitary and ventral skull base surgery performed by a single rhinologist between January 2017–March 2020 were included. There were 103 patients identified. Eighteen patients received 20 ITF injections due to clinical suspicion for CSF leak during the postoperative period without florid CSF rhinorrhea on clinical exam. Computed tomography scans with new or increasing intracranial air and intra-operative findings were used to confirm CSF leaks. Clinical courses were reviewed for at least 6 months after initial concern for leak as the final determinate of CSF leak. Main Outcome Measures: Specificity and safety of ITF Results: Eleven (61%) ITF patients were female and 7 (39%) were male. Average patient age was 52.50±11.89. There were 6 patients with confirmed postoperative CSF leaks, 3 of whom had evaluations with ITF. ITF use resulted in 2 true positives, 1 false negative, 17 true negatives and 0 false positives. ITF sensitivity was 67%, specificity was 100%, and positive and negative predictive values were 100% and 94.4%, respectively. There were no adverse effects from ITF use. Conclusions: Existing modalities for detecting postoperative CSF leaks suffer from suboptimal sensitivity and specificity, delayed result reporting, or limited availability. Intrathecal fluorescein represents a specific and safe test with potential utility in the postoperative setting.

Object Spontaneous and medically induced CSF leaks are uncommonly associated with pituitary adenomas. The aim of this study was to further characterize the clinical scenarios most closely associated with this phenomenon. Methods A review of the literature was conducted to identify all cases of nonsurgical CSF leaks associated with pituitary adenomas. The authors aimed to identify associated risk factors and management strategies used to treat these tumors and repair the CSF leak site. Results Fifty-two patients with spontaneous or medically induced CSF leaks in the setting of a pituitary adenoma were identified from 29 articles published from 1980 through 2011. In 38 patients (73%), CSF rhinorrhea developed following initiation of medical therapy, whereas spontaneous CSF leakage developed as the presenting symptom in 14 patients (27%). The patients' mean age was 42.8 years (range 23–68 years). There were 35 males and 17 females. Forty-two patients (81%) had a prolactinoma, with the remaining patients having the following tumors: nonfunctioning pituitary adenoma (6 patients), growth hormone–secreting adenoma (2 patients), mammosomatotroph cell adenoma (1 patient), and ACTH-secreting adenoma (1 patient). Infrasellar tumor invasion into the paranasal sinuses was specifically reported in 56% of patients. The medical agents associated with CSF leakage were dopamine agonists (97%) and somatostatin analogs (3%). The average time from initialization of medical treatment to onset of rhinorrhea was 3.3 months (range 3 days–17 months). Nonsurgical management was successful in 4 patients, including 1 who had successful resolution with a temporary lumbar drain. Forty-six patients (88%) underwent surgical intervention to treat the CSF leak and/or resect the tumor. In 2 patients, surgery was not performed due to medical contraindications or patient preference. Conclusions Nonsurgical development of CSF rhinorrhea may occur in the setting of pituitary adenomas, especially following favorable response of invasive prolactinomas to initiation of dopamine agonist therapy. Additional cases have been reported as the presenting symptom of a pituitary adenoma and are likely to be related to decreased tumor volume due to intrinsic infarction or hemorrhage, ongoing invasion, and/or increases in intracranial pressure. Surgical repair, preferentially via a transsphenoidal approach, is the recommended initial treatment for definitive repair of the CSF leak and achievement of maximal tumor resection.

Background Spontaneous cerebrospinal fluid (CSF) leaks are largely attributed to idiopathic intracranial hypertension and typically present as skull base defects with or without prolapse of intracranial contents. However, in our practice, we have encountered a distinct type of spontaneous CSF leak that presents in a different manner. Objective To discuss a newly-classified, difficult to treat, subset of spontaneous CSF leaks that present as excavation of the bone of the skull base in a tunnel- or canal-like fashion by a meningocele or meningoencephalocele instead of as a localized area of bony dehiscence. Methods A retrospective review was performed at a tertiary care rhinology practice to identify a subset of CSF leak patients with an excavating/canal-like skull base defect visualized radiographically on computed tomography (CT) scan or magnetic resonance imaging and/or endoscopically in the operating room. Results The cohort of patients consisted of 7 females and 1 male with an average age of 53.6 years and a self-reported race of 4:3:1 African-American: Caucasian-Indian. All patients presented with CSF rhinorrhea. The most common leak site was the cribriform and upper septum. Six of the 8 patients had multiple defects and/or progression of their skull base defects, and 5 patients required multiple and/or repeat repairs in the operating room. Seven of the 8 patients underwent a cisternogram because the excavating nature of the leaks made it difficult to identify the specific leak site on high-resolution CT scan alone. Conclusion In spontaneous CSF leaks that are difficult to identify or recur soon after a proper repair, an excavating pattern should be considered. Failure to recognize this type of leak and all of its tributaries, to fully unroof the excavated bone to completely resect the meningocele, and to visualize and close the site of origin will likely result in failure and recurrence of CSF leak.

ObjectiveTo compare surgical outcomes between 2 techniques for cribriform cerebrospinal fluid leak (CSF) repair with middle turbinate preservation (MTP) vs middle turbinate resection (MTR). A secondary outcome is to examine the effectiveness of collagen dura matrix (CDM) as a grafting material for repair of isolated cribriform skull base defects.Study DesignA retrospective chart review was performed of consecutive patients who underwent cribriform CSF repair at Emory University over the past 15 years.SettingTertiary care rhinology practice.SubjectsAdult patients with cribriform defects limited to the cribriform plate that did not extend lateral to the middle turbinate (MT) and were reconstructed with a free graft (mucosal or synthetic).MethodsPatients were stratified into 2 primary groups by surgical technique: MTP vs MTR. A subset of patients underwent repair with CDM alone and was analyzed separately for CSF repair failure rate.ResultsOf 68 patients identified with cribriform defects, 42 underwent repair with MTP and 26 underwent repair with MTR. Average follow-up time was 495 days. Patients with idiopathic intracranial hypertension were also equally distributed ( P = .20). Primary CSF leak repair success was 95.6%, with 100% of leaks ultimately repaired. A subset of 39 patients underwent repair with CDM alone, with a primary repair success rate of 94.9%.ConclusionsWe present an effective method for repair of cribriform CSF leaks while preserving the MT. CDM can be successfully used as a free graft alone for repair of isolated cribriform CSF leaks.

OBJECTIVE While multiple studies have evaluated the length of stay after endonasal transsphenoidal surgery (ETS) for pituitary adenoma, the potential for early discharge on postoperative day 1 (POD 1) remains unclear. The authors compared patients discharged on POD 1 with patients discharged on POD > 1 to better characterize factors that facilitate early discharge after ETS. METHODS A retrospective chart review was performed for patients undergoing ETS for pituitary adenoma at a single tertiary care academic center from February 2005 to February 2020. Discharge on POD 1 was defined as a discharge within 24 hours of surgery. RESULTS A total of 726 patients (mean age 55 years, 52% male) were identified, of whom 178 (24.5%) patients were discharged on POD 1. These patients were more likely to have pituitary incidentaloma (p = 0.001), require dural substitutes and DuraSeal (p = 0.0001), have fewer intraoperative CSF leaks (p = 0.02), and have lower postoperative complication rates (p = 0.006) compared with patients discharged on POD > 1. POD 1 patients also showed higher rates of macroadenomas (96.1% vs 91.4%, p = 0.03) and lower rates of functional tumors (p = 0.02). POD > 1 patients were more likely to have readmission within 30 days (p = 0.002), readmission after 30 days (p = 0.0001), nasal synechiae on follow-up (p = 0.003), diabetes insipidus (DI; 1.7% vs 9.8%, p = 0.0001), postoperative hypocortisolism (21.8% vs 12.1%, p = 0.01), and postoperative steroid usage (44.6% vs 59.7%, p = 0.003). The number of patients discharged on POD 1 significantly increased during each subsequent time epoch: 2005–2010, 2011–2015, and 2016–2020 (p = 0.0001). On multivariate analysis, DI (OR 7.02, 95% CI 2.01–24.57; p = 0.002) and intraoperative leak (OR 2.02, 95% CI 1.25–3.28; p = 0.004) were associated with increased risk for POD > 1 discharge, while operation epoch (OR 0.46, 95% CI 0.3–0.71; p = 0.0001) was associated with POD 1 discharge. CONCLUSIONS This study demonstrates that discharge on POD 1 after ETS for pituitary adenomas was safe and feasible and without increased risk of 30-day readmission. On multivariate analysis, surgical epoch was associated with decreased risk of prolonged length of stay, while factors associated with increased risk of prolonged length of stay included DI and intraoperative CSF leak. These findings may help in selecting patients who are deemed reasonable for safe, early discharge after pituitary adenoma resection.

AbstractObjective:Intraoperative identification of cerebrospinal fluid (CSF) leakage is critical in successful closure after endoscopic cranial base surgery. Intrathecal injection of fluorescein is quite useful in identifying CSF leaks. However, complications have been reported with various doses and the technique has fallen out of favor. We explored the safety of low-dose intrathecal fluorescein administered to patients undergoing endoscopic cranial base surgery.Methods:A retrospective chart review and postoperative patient survey were performed. The nature and incidence of complications and subjective complaints were recorded in 54 patients who underwent endoscopic, endonasal approaches to the anterior cranial base and received intrathecal fluorescein after premedication with dexamethasone and diphenhydramine.Results:Intraoperative CSF leak was identified with fluorescein in 46.3% of the patients and helped determine the reconstruction technique. Postoperative CSF leak occurred in 9.3% of the patients and resolved with lumbar drainage. There were no seizures. Most side effects were nonspecific, transient, and likely not caused by fluorescein including malaise (57.4%), headache (51.9%), dizziness (31.5%), or nausea/vomiting (24.1%). Three patients (5.6%) experienced persistent subjective lower extremity weakness (n = 2) and numbness (n = 2) postoperatively; however, two of them had undergone lumbar drainage.Conclusion:Low-dose injection of intrathecal fluorescein after premedication with steroid and antihistamine agents is generally safe. Most symptoms are nonspecific and transient, likely caused by the surgery or lumbar drainage. However, fluorescein should be administered with some caution because it may be responsible for occasional lower extremity weakness and numbness.
