title: [Treatment results of temporal bone area paragangliomas].
abstract: BACKGROUND
  Temporal bone paragangliomas are rare, benign neuroendocrine tumors. Depend on their location at skull base, they can extend intracranially and extracranially. They characterize by slowly growth and late nonspecific clinical manifestation. Location of tumor and anatomical condition require suitable operational technique and cause related complications.
  
  
  OBJECTIVE
  The aim of this study was analysis of surgical procedure and evaluation of treatment results of patients with paragangliomas of the temporal bone hospitalized in Department of Otolaryngology of Warsaw Medical University in years 2000-2010.
  
  
  METHODS
  34 cases of patients were retrospectively studied. Clinical data, level of tumor advancement according to Glasscock & Jackson and Fisch classification were analyzed. Intraoperative and imaging studies data were used to evaluate extent of lesions. Suitable operative approaches and outcome of treatment were also analyzed.
  
  
  CONCLUSIONS
  In group of 34 patients 26 of them had monocentric and 8 multicentric neoplasms. Age ranged 15-73-years-old. Most common symptoms were: loss of hearing, tinnitus and headache.
