Abstract Objective: A watertight and meticulous dural closure is an essential step after intradural neurosurgical procedures. When such a task cannot be performed, dural replacement materials and other adjunctive measures can provide an effective barrier between the subarachnoid compartment and the extradural space. Methods: We present our experience with a novel collagen-derived dural substitute in a series of 114 patients undergoing a variety of neurosurgical procedures. The patients were clinically or neuroradiologically observed, for immediate and delayed local or systemic complications related to the implant. In three patients who underwent reoperation after decompressive duraplasty and craniectomy for bone flap repositioning, we performed biopsy of the dural implant for histopathological studies. Results: None of the patients experienced local or systemic complications or toxicity related to the dural patch. None of the patients experienced a postoperative cerebrospinal fluid fistula, except one patient who underwent an endoscopic endonasal transsphenoidal marsupialization of a large intrasuprasellar arachnoid cyst; the fistula required reoperation for cerebrospinal fluid fistula repair and intravenous antibiotic therapy for bacterial meningitis. Postoperative magnetic resonance imaging scans showed signs of severe inflammatory response in only one patient who did not present any postoperative clinical symptom or neurological deficits. Three patients underwent reoperation for bone flap repositioning after decompressive craniectomy; in all patients, the dural substitute appeared to have promoted satisfactory dural regeneration, as confirmed by the histological studies. Furthermore, in such patients, no or minimal adherence with the other tissues and the brain cortex was observed. Conclusion: This study demonstrates that the new collagen-only biomatrix is a safe and effective dural substitute for routine neurosurgical procedures. The absence of local and systemic toxicity or complications and the scarce promotion of adherences and inflammation make this material appealing for its use as a dural substitute, even in cases in which the necessity of reoperation is foreseen.

<p class="abstract"><strong>Background:</strong> Cerebrospinal fluid (CSF) fistula is an abnormal CSF leakage due to bone and/or dural defect of the skull base and usually operated with endonasal endoscopic approach. The aim of this study was to determine the efficacy of an endonasal endoscopic approach in the repair of CSF leakage and to find the reasons of the recurrence of endoscopic procedure.</p><p class="abstract"><strong>Methods:</strong> The medical records of 24 patients that presented with the diagnosis of cerebrospinal fluid fistula and who had undergone endonasal endoscopic repair surgery were reviewed retrospectively.  </p><p class="abstract"><strong>Results:</strong> 13 patients (54.2%) were found to have spontaneous CSF fistulas without any history of trauma, while 11 patients (45.8%) had posttraumatic CSF fistulas. The mean body mass index (BMI) of patients was 31. 3 kg/m² (20.1-49.6). Nasal septal cartilage was used as a graft material in 19 patients (79%) while only fascia was used in 5 patients (21%). The evaluation of long-term results revealed recurrence in 4 patients (16.6%). Two of these patients required a second surgical repair.</p><p class="abstract"><strong>Conclusions:</strong> An endoscopic endonasal approach is a safe method with less morbidity and a reliable outcome in the repair of CSF fistulas. The most important causative factors in the recurrence of endoscopic repair of CSF leak might be to have high BMI and not to use multilayered graft material for closure of fistula.</p><p class="abstract"> </p>

Petromastoid Canal

Four locations for congenital cerebrospinal fluid fistula in the region of a normal labyrinth are reviewed. A congenital leak may occur through the petromastoid canal, a wide cochlear aqueduct, Hyrtl's fissure, or the facial canal. A fistula through the initial segment of the fallopian canal was successfully repaired in a two-year-old boy who had three episodes of meningitis following otitis media. Knowledge of these four sites of congenital defects provides a guideline for the surgeon in the identification and repair of cerebrospinal fluid leaks in the region of the labyrinth.

AbstractObjective:To present our experience in managing cerebrospinal fluid rhinorrhoea using the cartilage inlay (underlay) technique to repair skull base defects larger than 4 mm.Study design:Retrospective study involving patients presenting with cerebrospinal fluid rhinorrhoea between 1994 and 2008.Setting:Patients were treated in a tertiary referral centre for nose and sinus diseases. Patients' medical records were reviewed and analysed.Results:A total of 62 patients were operated upon using a cartilage inlay technique to repair bony skull base defects ranging in size from 4 to 20 mm (widest diameter). Of these 62 patients, 16 constituted revisions of earlier procedures undertaken elsewhere. The success rate of the technique was 100 per cent. Patient follow up ranged from six months to 16 years, with a median follow up of 15 months. Three patients had minor post-operative sinus infections; no serious complications were encountered.Conclusion:Extradural cartilage inlay appears to be an effective technique in the management of cerebrospinal fluid rhinorrhoea, especially for large defects and revision procedures. To our knowledge, the described patients represent the largest reported series of cerebrospinal fluid rhinorrhoea cases managed using the cartilage inlay technique. We believe that the crucial factors in our high success rate for cerebrospinal fluid fistula repair are: precise identification of the bony defect; meticulous preparation of the graft bed; careful elevation of the dura; judicious use of just enough graft tissue; and adequate graft support.
