The authors present a fully endoscopic endonasal repair of a spontaneous CSF leak caused by a defect in the anterior fossa floor. Patients were positioned supine in a Mayfield headholder in slight extension. A complete ethmoidectomy was performed to expose the defect. The middle turbinate was removed to increase visualization and allow for more working room. The defect was identified and exposed. A nasoseptal flap was raised and placed over the defect. A free-mucosal graft fashioned from the removed middle turbinate was placed on the nasoseptal donor site. The video can be found here: http://youtu.be/gAN2cvQVXCE.

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.

The Impact

OBJECTIVEEpidermoid cysts (ECs) commonly extend to involve the ventral cisterns of the cranial base. When present, symptoms arise due to progressive mass effect on the brainstem and adjacent cranial nerves. Historically, a variety of open microsurgical approaches have been used for resection of ECs in this intricate region. In recent years, the endoscopic endonasal approach (EEA) has been proposed as an alternative corridor that avoids crossing the plane of the cranial nerves. To date, there is a paucity of data in the literature regarding the safety and efficacy of the EEA in the treatment of ECs of the ventral cranial base.METHODSThe authors reviewed a prospectively acquired database of EEAs for resection of ECs over 8 years at Weill Cornell, NewYork-Presbyterian Hospital. All procedures were performed by the senior authors. Standardized clinical and radiological parameters were assessed before and after surgery. Statistical tests were used to determine the impact of previous surgery and tumor volume on extent of resection and recurrence as well as the method of closure on rate of CSF leak.RESULTSBetween January 2009 and February 2017, 7 patients (4 males and 3 females; age range 16–70 years) underwent a total of 8 surgeries for EC resection utilizing the EEA. Transplanum and transclival extensions were performed in 3 and 5 patients, respectively. Methods of closure incorporated a gasket seal in 6 of 8 procedures and a nasoseptal flap in 7 of 8 procedures. Gross-total resection (GTR) was achieved in 43% of patients, and near-total resection (> 95%) was obtained in another 43%. Complications included diabetes insipidus (n = 2), postoperative CSF leak (n = 2), transient third cranial nerve palsy (n = 1), and epistaxis (n = 1). With a mean follow-up of 43.5 months, recurrence has been observed in 2 of 7 patients. In 1 case, reoperation for recurrence was required 71 months following the initial surgery. Use of the gasket-seal technique with nasoseptal flap coverage significantly correlated with the absence of postoperative CSF leakage (p = 0.018). GTR was achieved in 25% of the patients who had prior surgeries and in 50% of patients without previous resections. The mean volume of cysts in which GTR was achieved (4.3 ± 1.8 cm3) was smaller than that in which subtotal or near-total resection was achieved (12.2 ± 11 cm3, p = 0.134).CONCLUSIONSThe EEA for resection of ECs of the ventral cranial base is a safe and effective operative strategy that avoids crossing the plane of the cranial nerves. In the authors’ experience, gasket-seal closure with nasoseptal flap coverage has been associated with a decreased risk of postoperative CSF leakage.

OBJECTIVEThe vascularized nasoseptal flap (NSF) has become the workhorse for skull base reconstruction during endoscopic endonasal surgery (EES) of the ventral skull base. Although infrequently reported, as with any vascularized flap the NSF may undergo ischemic necrosis and become a nidus for infection. The University of Pittsburgh Medical Center’s experience with NSF was reviewed to determine the incidence of necrotic NSF in patients following EES and describe the clinical presentation, imaging characteristics, and risk factors associated with this complication.METHODSThe electronic medical records of 1285 consecutive patients who underwent EES at the University of Pittsburgh Medical Center between January 2010 and December 2014 were retrospectively reviewed. From this first group, a list of all patients in whom NSF was used for reconstruction was generated and further refined to determine if the patient returned to the operating room and the cause of this reexploration. Patients were included in the final analysis if they underwent endoscopic reexploration for suspected CSF leak or meningitis. Those patients who returned to the operating room for staged surgery or hematoma were excluded. Two neurosurgeons and a neuroradiologist, who were blinded to each other’s results, assessed the MRI characteristics of the included patients.RESULTSIn total, 601 patients underwent NSF reconstruction during the study period, and 49 patients met the criteria for inclusion in the final analysis. On endoscopic exploration, 8 patients had a necrotic, nonviable NSF, while 41 patients had a viable NSF with a CSF leak. The group of patients with a necrotic, nonviable NSF was then compared with the group with viable NSF. All 8 patients with a necrotic NSF had clinical and laboratory evidence indicative of meningitis compared with 9 of 41 patients with a viable NSF (p < 0.001). Four patients with necrotic flaps developed epidural empyema compared with 2 of 41 patients in the viable NSF group (p = 0.02). The lack of NSF enhancement on MR (p < 0.001), prior surgery (p = 0.043), and the use of a fat graft (p = 0.004) were associated with necrotic NSF.CONCLUSIONSThe signs of meningitis after EES in the absence of a clear CSF leak with the lack of NSF enhancement on MRI should raise the suspicion of necrotic NSF. These patients should undergo prompt exploration and debridement of nonviable tissue with revision of skull base reconstruction.

The authors present the case of a 21-year-old female with a progressive bitemporal hemianopsia. Cranial MR imaging revealed a large cystic suprasellar, retrochiasmatic lesion consistent with craniopharyngioma. The lesion was fully resected through an endoscopic endonasal transsphenoidal and transplanum approach. Closure of the resultant dural defect was performed with a bilayer fascia lata button and autologous mucoperichondrial nasoseptal flap. Each portion of this procedure was recorded and is presented in an edited high-definition format. The video can be found here: http://youtu.be/i3-qieLlbVk.

Fluid Leak

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.

Abstract We present a case of cerebrospinal fluid (CSF) leak after endoscopic endonasal resection of a large clival chordoma in an obese patient. The leak was at the lower reconstruction at the craniocervical junction and had failed repositioning. Using the V-Loc™ wound closure device (Covidien, New Haven, Connecticut) to suture the nasoseptal flap to the nasopharyngeal fascia, a water-tight seal was created and, along with a lumbar drain, the patient healed successfully. CSF leak after an endoscopic endonasal approach (EEA) to intradural pathologies remains one of the more common complications.1-4 Various closure techniques have been developed5-8 with success in mitigating this risk, but all have their limitations and rely on multiple layers including vascularized flaps like the nasoseptal flap.9-11 Endonasal suturing of graft materials offers the advantage of creating a water-tight seal. We present the use of the V-Loc™ wound closure device (Covidien) to successfully seal a postoperative CSF leak. The absorbable V-Loc™ wound closure device does not require the surgeon to tie knots, which is the most challenging step in a deep, 2-dimensional corridor. The suture is barbed and is anchored by threading the needle through a prefabricated loop at the end of the suture which locks in place. Each throw of the suture through tissue maintains the suture line as the barbs catch the tissue and prevent retraction. After successful closure, the needle can simply be cut off. The V-Loc™ wound closure device (Covidien) is a safe and effective adjunct to reconstruction after endoscopic endonasal skull base surgery as it provides an option for graft/flap suturing. A written release from the patient whose name or likeness is submitted as part of this Work is on file.

Operative Outcome

Background: Naso-septal Rescue Flap(NSRF) technique involves the preservation of unilateral posterior septal artery pedicle without harvesting full Naso-Septal Flap (NSF). This enables usage of NSF flap when needed while allowing enough exposure to resect tumor completely. This also provides with added advantage of tailoring flap according to preference to cover the defect post tumor removal. This technique involves partial harvestation of only the most superior and posterior aspect of the flap to protect its pedicle, providing better instrumentation for the sphenoid sinus. At the end of the procedure, if there is unexpected CSF rhinorrhea or resultant bony defect is large then Nasoseptal flap is harvested from the rescue flap. As very few studies have been conducted for rescue flap technique in anterior skull base defect reconstruction following excision of sellar/supra-sellar lesions, the technique requires further validation, hence the present study is being undertaken. Objectives: To study the post-operative outcome of Nasal Septal Rescue Flap (NSRF) in terms of donor site morbidity and CSF leak. To study the post-operative outcome of posterior nasoseptal flap in terms of donor site morbidity and CSF leak. Methodology: A cross-sectional study will be conducted at Department of E.N.T, AVBRH, Sawangi Wardha, during a period of August 2020 to August 2021. A sample size of 20 within 18 -70 years of age with sellar/supra-sellar lesions will be included for the research. Results: The observations obtained will be analyzed statistically and will be discussed in light of literature available. Conclusion: This study will help in formulating the guidelines for the NSF harvest with the goal of preventing unnecessary harvest, thereby decreasing peri-operative and post-operative disadvantages as well as preserving the flap for reconstruction in patients requiring revision surgery.

Background: Vascularized nasoseptal flaps allow for the reconstruction of large dural defects and have remarkably reduced the incidence of postoperative complications during endoscopic endonasal skull base surgery. Nevertheless, some complications related to nasoseptal flap have been reported. Flap necrosis is a rare, but serious issue is associated with meningitis and cerebrospinal fluid (CSF) leak. Case Description: We performed endoscopic endonasal removal of the tuberculum sella meningioma in a 39-year-old woman with a history of Turner syndrome using abdominal fat, fascia, and a vascularized nasoseptal flap for dural and skull base defect reconstruction. After surgery, she developed CSF leak, and reoperation revealed partial necrosis of the septal flap that caused leakage. At this time, with a concern that removal of the necrotic part may lead to the insufficient size of the flap, we filled the gap tightly with fat pieces. However, the CSF leak recurred, and thus, we performed debridement of the necrotic region and reformed the multilayered reconstruction, following which she no longer experienced CSF leakage. Conclusion: Our case suggested that partial rather than total flap necrosis could occur, possibly due to variances of vascular anatomy, leading to focal ischemia. Debridement of the necrotic region may be an important solution for recurrent cerebrospinal leakage secondary to partial necrosis of a nasoseptal flap.
