Ear Drum Surgery for Perforations
A perforated ear drum (tympanic membrane) can cause conductive hearing loss by disrupting sound transmission to the middle ear bones. This damage often results from injury or repeated infections and may also affect the ossicular chain.
Tympanoplasty is the procedure used to repair the ear drum, and it may include ossicular chain reconstruction if the bones are damaged. The surgery uses a small tissue graft, typically taken from behind the ear, to restore the drum’s function and improve hearing.
Frequently Asked Questions
A perforated ear drum can result from injury, such as trauma to the ear, or from repeated ear infections. These causes can damage the tympanic membrane and potentially affect hearing.
A perforated ear drum disrupts the normal transmission of sound to the middle ear bones, causing conductive hearing loss. This interference reduces the efficiency of sound conduction, leading to partial hearing impairment.
Tympanoplasty is a surgical procedure used to repair a perforated ear drum. It involves using a small tissue graft, often taken from behind the ear, to close the perforation and restore the ear drum's function to improve hearing.
Ossicular chain reconstruction is performed during tympanoplasty if the middle ear bones are damaged in addition to the ear drum perforation. This helps restore the proper conduction of sound to improve hearing outcomes.
The graft used in tympanoplasty to repair the ear drum is typically a small piece of tissue taken from behind the ear. This tissue effectively helps close the perforation and promotes healing.
