title: Pneumocephalus after acoustic neuroma surgery.
abstract: OBJECTIVE
  The study was conducted to describe the diagnosis and management of pneumocephalus after acoustic tumor resection.
  
  
  METHODS
  The study design was a retrospective chart review.
  
  
  METHODS
  The study was conducted as a tertiary otologic referral to the senior authors' practices (PAF, MDA).
  
  
  METHODS
  Three patients operated on for acoustic tumor in St. Vincent's General Hospital and the Scottish Hospital, Sydney, Australia, were studied.
  
  
  METHODS
  Observation in both cases and surgery in a case in which tension pneumocephalus was progressive were performed.
  
  
  METHODS
  Recovery will follow either spontaneously or after intervention.
  
  
  RESULTS
  All patients had an uneventful recovery.
  
  
  CONCLUSIONS
  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.
