Management of pseudomeningocele following neurotologic procedures.
OBJECTIVES: A pseudomeningocele results from the escape of cerebrospinal fluid through a dural defect with trapping of subarachnoid fluid in surrounding soft tissue. The present study evaluates the incidence of pseudomeningocele following neurotologic procedures and delineates an algorithm for management.
METHODS: A retrospective review of 375 consecutive patients undergoing neurotologic procedures at a single institution identified 17 patients with the postoperative complication of pseudomeningocele.
RESULTS: The incidence of pseudomeningocele formation was 4.5% in the present study. Fourteen pseudomeningoceles resolved with nonoperative management including pressure dressing, bed rest, and lumbar spinal drainage. Three patients failed nonoperative management and required surgical procedures for resolution. All patients ultimately had resolution of their pseudomeningocele.
CONCLUSION: Skull-base pseudomeningoceles occur as a complication following neurotologic procedures and can cause complications as they enlarge. The majority of these cases can be dealt with in a nonsurgical manner, but those failing to respond to conservative management should be considered for surgical intervention.
