Necessity of mastoidectomy in patients with chronic otitis media having sclerotic mastoid bone: a retrospective clinical study.

Objectives: 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.

Patients And 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.

Conclusion: Mastoidectomy is not an efficient procedure in chronic otitis media patients having sclerotic mastoid bone with dry or dried up tympanic cavity.
