Summary
Prophylactic antibiotics are not essential for endonasal duraplasty in most patients with cerebrospinal fluid (CSF) fistulae. This approach can be safely performed without antibiotic cover, especially for smaller lesions and low-risk individuals.
Area of Science:
- Neurosurgery
- Otolaryngology
- Infectious Disease
Background:
- Evidence does not consistently support prophylactic antibiotics for cerebrospinal fluid (CSF) fistulae.
- The necessity of antibiotic prophylaxis or therapy for operative closure of frontobasal dural lesions remains a question.
Purpose of the Study:
- To evaluate the efficacy and safety of endonasal duraplasty without antibiotic prophylaxis.
- To determine if antibiotic cover is mandatory for operative closure of frontobasal dural lesions.
Main Methods:
- A retrospective survey of 7 patients undergoing endonasal duraplasty without pre- or intraoperative antibiotics.
- Evaluation of hospital course, post-operative complications (including meningitis), need for antibiotic therapy, and diagnostic tests like the fluorescein test.
Main Results:
- 6 out of 7 patients had an uneventful postoperative course without inflammatory complications.
- No meningitis occurred in any patient; all duraplasties were successfully closed.
- One patient received antibiotics post-operatively due to fever; 5 had a negative fluorescein test.
Conclusions:
- Endonasal duraplasty is a satisfactory surgical approach for dural closure.
- Antibiotic prophylaxis may not be essential for endonasal duraplasty in small lesions without specific risk factors.
- Larger patient populations are needed to confirm these findings regarding antibiotic necessity.
