Middle ear surgical results in hearing improvement with tympanosclerosis

Abstract

Background: Tympanosclerosis is one of complications of chronic otitis media with accumulation of hyaline and calcified deposits intra tympanic membrane and middle ear's membrane. In most cases these plaques are of minimal clinical significance and result in trivial hearing dysfunction. Methods: 60 patients diagnosed with chronic otitis media and tympanosclerosis who were candidates for operation and met inclusion criteria were evaluated. Audiometric evaluations were assessed before and after surgery. Intra operative findings and Post operative clinical results were also evaluated after surgery. Results: 25(43.1%) patients were male and 33(56.9%) were female. Hearing dysfunction was monolateral in 62.1% and bilateral in 37.9%. The most common location of ossicular chain fixation is between incus and malleus reported in 24(41.3%) patients. Conclusion: Middle ear surgery result is astonishing although other factors such as severity of sclerosis and fixation localization may also be influential in surgical results.
