Abstract
OBJECTIVES: To determine the necessity for lumbar drains during endoscopic cerebrospinal fluid (CSF) rhinorrhea repair.
METHODS: Thirty-three patients underwent endoscopic repair of CSF rhinorrhea without a lumbar drain during a 7-year period. The size of the dural defect ranged from a microleak (less than 1 mm dural defect) to a 3-cm dural defect of the anterior skull base.
RESULTS: All of the procedures in patients with smaller defects (<5 mm) were performed on an outpatient basis. Thirty-two patients (97%) had complete resolution of their CSF leak after 1 procedure without any recurrence (average follow-up 29 months).
CONCLUSION: A lumbar drain is not routinely necessary for successful closure of CSF rhinorrhea of any size. Smaller dural defects may be safely performed on an outpatient basis without complications. (Otolaryngol Head Neck Surg 1999;121:745-50.)
