Surgery of tympanosclerosis

Area of Science:

• Otolaryngology
• Audiology
• Pathophysiology

Background:

• Tympanosclerosis is a common finding in the middle ear, often associated with chronic otitis media.
• Surgical intervention is frequently required for symptomatic tympanosclerosis, especially when it affects hearing or middle ear structures.

Purpose of the Study:

• To classify tympanosclerosis based on patho-physiological characteristics.
• To evaluate the efficacy of surgical management, including a two-stage procedure, for tympanosclerosis.
• To assess post-operative hearing outcomes in patients undergoing surgery for tympanosclerosis.

Main Methods:

• Retrospective analysis of 85 surgically treated cases of tympanosclerosis from 1984 to 1995.
• Classification of tympanosclerosis based on patho-physiological criteria.
• Application of a planned two-stage surgical procedure in 36 cases, with an 18-month interval.
• Statistical analysis of hearing improvement using Chi-square (chi 2) and the Glasgow Benefit Plot.

Main Results:

• Satisfactory short-term hearing improvement (2-5 years post-operatively) was observed in the majority of patients.
• A two-stage procedure was predominantly used for stapes surgery.
• One case of anacusis and one recurrence were noted in patients not undergoing stapes surgery.

Conclusions:

• Surgical treatment, particularly staged procedures, can lead to satisfactory short-term hearing improvement in tympanosclerosis.
• Further research may be needed to fully understand long-term outcomes and rare complications like anacusis and recurrence.
