Object The goal of this study was to demonstrate the efficacy of a simple and reliable technique for anterior skull base and craniofacial reconstruction in patients who have undergone excision of tumors via the subcranial approach. Methods There were 63 patients who had undergone 71 anterior skull base resections of tumors via the aforementioned approach. Twenty-nine cases (41%) involved malignant tumors and 42 (59%) involved benign tumors. Reconstruction of the anterior skull base was performed by a single team who used double-layer fascial graft. Limited dural defects were reconstructed using the temporalis fascia, whereas large anterior skull base defects were reconstructed using a fascia lata sheath. Reconstruction was achieved without the support of bone graft or titanium mesh and without pericranial, galeal, or free flaps. Pericranial flap wrapping of the frontonasoorbital segment was performed to prevent osteoradionecrosis if postoperative radiotherapy was planned. The incidence of cerebrospinal fluid (CSF) leakage, intracranial infection, and tension pneumocephalus was 5.6%. Histopathological examination of fascia lata grafts obtained in patients who had undergone a second procedure demonstrated integration of vascularized fibrous tissue to the graft, as well as local proliferation of a newly formed vascular layer embedding the fascial sheath. Conclusions The use of a double-layer fascial graft alone was adequate for prevention of CSF leakage, meningitis, tension pneumocephalus, and brain herniation. The double-layer fascial flap provided a simple and reliable means for anterior skull base reconstruction after en bloc resection of both malignant and benign tumors.

Abstract Background : Cerebro-spinal fluid rhinorrhea may follow surgical and traumatic events, and may be spontaneous. Various techniques have been employed for reconstruction of the skull base following a CSF leak. Recent years have seen the development of endoscopic, transnasal techniques for reconstruction of the anterior skull base. We describe our experience with a novel corkscrew technique (CST), which entails harvesting a fascia lata graft, and placement of a wedge-shaped construct above the aperture in the skull base dura. This technique serves to prevent dislodgement of the construct extracranially, and lateral displacement of the construct away from the opening. Methods : We operated 28 cases of CSF leak, in 26 patients, with a transnasal endoscopic approach. Twelve were operated using the CST and 16 with standard technique (ST), with a mean follow-up of over 5 years.Results : The success rate in alleviating the leak was 91.7% in the CST group, and 87.5% in the ST group. Altogether, our complication rate was 8.3% in the CST group, and 37.5% in the ST group. None of the differences were statistically significant. Conclusions : We recommend the use of a wedge-shaped, fascia lata based construct for transnasal endoscopic repair of anterior skull base CSF leaks.

Abstract Background Pedicled nasoseptal flap (PNSF) has significantly improved the surgical outcomes of endoscopic endonasal approach (EEAs) by reducing cerebrospinal fluid (CSF) leakage. The purpose of this study is to assess the feasibility of using a PNSF for anterior skull base (ASB) reconstruction and to describe a method to compensate for a short flap based on our results. Methods In this cadaveric study, ASB dissection without sphenoidotomy was performed using 10 formalin-fixed and 5 fresh adult cadaver specimens, and the sufficiency of the PNSF to cover the ASB was assessed. After the sphenoidotomy, the length by which the PNSF fell short in providing coverage at the posterior wall of the frontal sinus (CPFS), and the extent of the anterior coverage from the limbus (CL) of the sphenoid bone was measured. Results Without sphenoidotomy, the mean length of the remaining PNSF after the coverage of the posterior wall of the frontal sinus was 0.67 cm. After sphenoidotomy, the PNSF fell short by a mean length of 2.10 cm, in providing CPFS. The CL was 1.86 cm. Based on these findings, defects resulting from an endoscopic resection of ASB tumors were reconstructed using PNSF without total sphenoidotomy in 3 patients. There were no postoperative CSF leaks or complications. Conclusions The use of PNSF for ASB reconstruction may be insufficient to cover the entire ASB defect after removal of large lesions which need total sphenoidotomy. When possible, by leaving some portion of the anterior sphenoid wall for supporting the PNSF, successful ASB reconstruction could be achieved in endoscopic resection of ASB tumors. Additional methods might be needed in some cases of large ASB lesions wherein the anterior sphenoid wall should be removed totally and the ASB defect is too large.

Abstract Objectives Reconstruction after open surgery of anterior skull base lesions is challenging. The fascia lata graft is our workhorse for achieving dural sealing and preventing cerebrospinal fluid leak and meningitis. This study seeks to analyze the donor and recipient site complication rates after fascia lata reconstruction. Methods This is a retrospective review of all open anterior skull base operations in which a double-layer fascia lata graft was used for the reconstruction of the defect from 2000 to 2016 at the Tel-Aviv Sourasky Medical Center, a tertiary referral center in Israel. Results Of the 369 patients operated for skull base lesions, 119 underwent open anterior skull base surgery and were reconstructed with a fascia lata graft. The patients' mean age was 47.1 years, and 68 (57.1%) were males. The overall postoperative early and late donor site complication rates were 6.7% (n = 8) and 5.9% (n = 7), respectively. Multivariate analysis found minor comorbidities and persistent/recurrent disease as being predictors for early-term complications. The overall postoperative early central nervous system (CNS) complication rate was 21.8% (n = 26), while 12.6% (n = 15) of the patients had late postoperative CNS complications. Conclusion Reconstruction of open anterior skull base lesions with fascia lata grafting is a safe procedure with acceptable complication and donor site morbidity rates.

The advent and widespread development of endonasal endoscopic techniques have recently expanded the frontiers of skull base surgery. The reduced invasiveness, wider and adjustable visualization of the operative field, and lack of postoperative cosmetic defects are well-known advantages of the endonasal endoscopic approaches compared with traditional surgical exposures both in adults and in children. The need to avoid disruption of facial growth centers and permanent tooth roots represents a further special consideration in favor of these endoscopic techniques in children. The authors report on a case of solitary myofibroma involving the ethmoid, mesial orbits, and anterior skull base with intracranial intradural expansion in a 17-month-old girl. The occurrence of such proliferative disease along the skull base is exceedingly rare. The tumor was successfully excised via an endoscopy-assisted cranionasal approach in which a transcranial microsurgical exposure was combined with endonasal endoscopic access to ensure a radical resection and optimize skull base reconstruction. To the authors' knowledge, the patient in this case is the youngest reported patient in the literature who has undergone treatment with this surgical strategy. The outcome in this patient underscores the feasibility and safety of endoscopic endonasal surgery even in toddlers and early childhood.
