title: Sinus wall reconstruction for sigmoid sinus diverticulum and dehiscence: a standardized surgical procedure for a range of radiographic findings.
abstract: OBJECTIVE
  To describe the radiographic presentation, surgical treatment, and complications of pulse-synchronous tinnitus (PST) due to sigmoid sinus diverticulum and dehiscence.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  Tertiary care, academic medical center.
  
  
  METHODS
  Thirteen patients (14 ears) surgically treated for PST due to sigmoid sinus diverticulum and dehiscence.
  
  
  METHODS
  Transmastoid reconstruction of the sinus wall with a standardized technique.
  
  
  METHODS
  Resolution of PST and complications of surgery.
  
  
  RESULTS
  All patients had complete resolution of their PST after surgery. There were 2 major postoperative complications, neither of which resulted in permanent morbidity.
  
  
  CONCLUSIONS
  Sigmoid sinus diverticulum and dehiscence is a surgically treatable cause of PST, with a high rate of success. The radiographic diagnosis may be subtle and easily overlooked. Complications of surgery can be serious, and vigilance must be maintained to ensure prompt diagnosis and treatment.
