Objective:
The study was conducted to describe the diagnosis and management of pneumocephalus after acoustic tumor resection.
Study Design:
The study design was a retrospective chart review.
Setting:
The study was conducted as a tertiary otologic referral to the senior authors' practices (PAF, MDA).
Participants:
Three patients operated on for acoustic tumor in St. Vincent's General Hospital and the Scottish Hospital, Sydney, Australia, were studied.
Intervention:
Observation in both cases and surgery in a case in which tension pneumocephalus was progressive were performed.
Main Outcome Measure:
Recovery will follow either spontaneously or after intervention.
Results:
All patients had an uneventful recovery.
Conclusion:
In most cases, spontaneous resolution occurs. However, if surgical re-exploration is indicated, it is best performed via the blind sac subtotal petrosectomy of Fisch.
