Understanding Cholesteatoma
Cholesteatoma is a benign growth behind the eardrum caused by trapped skin cells and keratin. Normally shed during ear cleaning, if this skin penetrates the eardrum, it can build up and form a cholesteatoma. Untreated, it may erode the ossicles, causing hearing loss, and can spread to the mastoid or inner ear, leading to permanent hearing damage. Serious complications, such as facial paralysis, hydrocephalus, meningitis, or a brain abscess, may arise and often require surgical removal.
Cholesteatoma Surgery and Treatment
The main aim of treatment for cholesteatoma is to control infection and prevent bone damage, with hearing restoration being secondary. For small cholesteatomas with manageable hearing loss, microscopic cleaning during an office visit may suffice. However, advanced cases typically require surgery, such as mastoidectomy, to remove the cholesteatoma and infections from the mastoid bone.
Additional procedures might include tympanoplasty to reconstruct the eardrum and ossicular reconstruction to replace eroded middle ear bones with prosthetics. Since cholesteatomas can recur, diligent post-surgical follow-up is crucial, and further surgery may be necessary to ensure complete removal.
Frequently Asked Questions
A cholesteatoma is a benign growth behind the eardrum caused by trapped skin cells and keratin. Normally, these skin cells are shed during ear cleaning, but if they penetrate the eardrum, they can accumulate and form a cholesteatoma. This growth can cause serious ear damage if left untreated.
If untreated, a cholesteatoma can erode the ossicles causing hearing loss, and may spread to the mastoid or inner ear leading to permanent hearing damage. Serious complications include facial paralysis, hydrocephalus, meningitis, or a brain abscess, all of which require prompt medical intervention.
Treatment aims first to control infection and prevent bone damage, with hearing restoration being secondary. Small cholesteatomas may be cleaned microscopically during an office visit, while advanced cases often require surgical procedures such as mastoidectomy to remove the growth and infection from the mastoid bone.
The primary surgery for cholesteatoma removal is mastoidectomy, which removes the cholesteatoma and infected tissue from the mastoid bone. Additional procedures like tympanoplasty may be performed to reconstruct the eardrum, and ossicular reconstruction may replace damaged middle ear bones with prosthetics to help restore hearing.
Cholesteatomas can recur even after surgical removal. Diligent post-surgical follow-up is essential to monitor healing and detect any regrowth early. Additional surgery may be necessary to ensure complete removal and prevent further complications.
While hearing restoration is a secondary goal, surgical procedures such as ossicular reconstruction can help improve hearing by replacing eroded middle ear bones with prosthetics. However, the primary aim is to control infection and prevent further damage to preserve existing hearing.
