title: Necessity of mastoidectomy in patients with chronic otitis media having sclerotic mastoid bone: a retrospective clinical study.
abstract: OBJECTIVE
  This study aims to investigate the efficiency of mastoidectomy during tympanoplasty procedures in patients having sclerotic mastoid bone with dry or dried up tympanic cavity.
  
  
  METHODS
  The study included 146 patients (66 males, 80 females; mean age 28.6 years; range 16 to 52 years) having sclerotic mastoid bone who underwent tympanoplasty between March 2010 and March 2013. Patients were divided into two groups: group A (34 males, 58 females; mean age 25.8 years; range 17 to 47 years) underwent only tympanoplasty, while tympanoplasty + mastoidectomy were performed on group B (32 males, 22 females; mean age 29.8 years; range 16 to 52 years). All outcomes were evaluated including the actual state of the tympanic membrane graft and level of hearing.
  
  
  RESULTS
  While postoperative perforation and retraction rates were not significantly different between the two groups, results of group A were superior to group B in terms of operation duration and hearing results.
  
  
  CONCLUSIONS
  Mastoidectomy is not an efficient procedure in chronic otitis media patients having sclerotic mastoid bone with dry or dried up tympanic cavity.
