Peri-operative management of endoscopic endonasal cerebrospinal fluid leak repair: an international survey
Résumé
Purpose: Peri-operative management of nasal cerebrospinal fluid (CSF) leaks is not consensual due to limited evidence. The main aim of this study was to identify key factors in peri-operative management of endoscopic endonasal CSF leak repair among international experts.
Methods: A 60-item survey questionnaire collected opinions of members of international learned societies of ENT surgeons and neurosurgeons on nasal packing, post-operative instructions, antibiotic prophylaxis, and CSF volume depletion.
Results: The survey had 153 respondents (124 otorhinolaryngologists and 29 neurosurgeons). A resting position was recommended by 85% (130/151) of respondents for extended CSF leak of the anterior skull base, mainly in Fowler’s position (72% (110/153)). Nasal packing was used by 85% (130/153) of respondents; 33.3% (51/153) used it to stabilize the reconstruction, and 22.2% (34/153) to prevent bleeding. It was usually removed after 48 h in 44.4% of cases (68/153). CSF depletion was considered by 47.1% (72/153) of respondents in case of CSF leak recurrence and by 34.6% (53/153) in cases of increased intracranial pressure. All respondents gave specific postoperative instructions to patients including driving, running, swimming, diving restrictions and flighting restrictions. In subgroup analysis, ENT surgeons more often recommended a resting position than neurosurgeons (71% vs. 37.9% ; p = 0.0008) and prescribed more antibiotics (82.3% vs. 21.4% ; p < 0.0001).
Conclusion: Although postoperative management after CSF closure remains challenging and not codified, this international survey revealed some points of consensus concerning resting position and restriction of post-operative activities. Prospective clinical studies must be undertaken to evaluate their efficiency.
