title: [Lateral petrosectomy in pathology of the temporal bone].
abstract: BACKGROUND
  Certain problems in ear surgery are caused by temporal bone cholestetoma and chronic otitis media complicated by deafness, facial nerve dysfunction, vertigo or meningcephalocele. Lateral petrosectomy offers possibility of radical treatment and prevention of temporal bone destruction and following complications.
  
  
  OBJECTIVE
  It is an analysis of indications for lateral petrosectomy and it's results as a treatment of otitis media and temporal bone cholesteatoma. The possibility of synchronous cochlear implantation is noted.
  
  
  METHODS
  Retrospective analysis of 62 patients after lateral petrosectomy, operated in the Department of Otolaryngology at the Medical University of Warsaw in 2001-2009. The group consisted of thirty one men and thirty one women.
  
  
  RESULTS
  Thirty two patients suffered from chronic granuloma or chronic choleateatoma otitis media or temporal bone cholesteatoma. Seventeen patients suffered from deafness prior surgery. Cochlear implantation was possible in five patients: two of them after cranium fracture, two with deafness caused by chronic otitis media and one with deafness caused by osteoradionecrosis. Intraoperative CSF leak was observed of eight patients. In one case lateral perosectomy was used as a treatment of CSF leak after removal of cerebellopontine tumor. There was no evidence of CSF leak after surgery. Facial nerve dysfunction was observed in fifteen cases.
  
  
  CONCLUSIONS
  Lateral petrosectomy offers possibility of radical treatment in same patients with chronic otorrhea. The total removal of cholesteatoma prevents intracranial and intratemporal complications in case of chronic otitis media. Patients after lateral petrosectomy require systematic ENT and radiological (CT, NMR) examination.
