Abstract
Any type of otosurgical procedure involves the risk of inner ear damage. As middle ear surgery is also performed for functional reasons this risk should be taken into consideration.
Myringoplasty is one of the various surgical techniques for the management of (CSOM-TT) disease. It is defined as simple surgical repair of a (TM) perforation without ossicular reconstruction. The presence of a perforation of TM with intermittent discharge and hearing loss of conductive nature are the indications of myringoplasty. It is a beneficial procedure done for closing TM and improving hearing.
The measurement of BC is not necessarily a true reflection of the function of the inner ear. Middle ear makes a contribution to BC and correction of a middle ear conductive lesion causes an apparent improvement in inner ear function.
The study showed that no significant change in bone conduction by improvement or worsening following myringoplasty by one month either with permeatal or postauricular approach with tragal cartilage graft , and there is no risk of inner ear depression or cochlear damage after myringoplasty.
No obvious difference between permeatal and postauricular approaches as regard improvement of hearing measured by air bone gap from audiometry pre- and one month postoperative, and so the selection of approach depends on another factors other than hearing improvement.
