A 'residual cholesteatoma' may develop if the initial surgery failed to completely remove the original; residual cholesteatomas typically become evident within the first few years after the initial surgery. A 'recurrent cholesteatoma' is a new cholesteatoma that develops when the underlying causes of the initial cholesteatoma are still present.
A mastoidectomy is a procedure performed to remove the mastoid air cells [1] near the middle ear. The procedure is part of the treatment for mastoiditis, chronic suppurative otitis media or cholesteatoma. [2]
Surgery for cholesteatoma offers the most advantages for using the endoscope instead of the microscope. Failures in cholesteatoma surgery are most common in certain areas of the anatomy of the tympanic cavity, such as the facial recess, sinus tympani, anterior attic, and the protympanum which are poorly accessed with the microscope.

Some mastoiditis is caused by cholesteatoma, which is a sac of keratinizing squamous epithelium in the middle ear that usually results from repeated middle-ear infections. If left untreated, the cholesteatoma can erode into the mastoid process, producing mastoiditis, as well as other complications.
Otology and neurotology encompass more complex surgery of the inner ear not typically performed by general otolaryngologists, such as removal of vestibular schwannoma, cholesteatoma, labyrinthectomy, surgery of the endolymphatic sac for Ménière's disease and cochlear implant surgery.
Surgery may be required if there is extension into the mastoid bone, or if a concurrent cholesteatoma is identified during surgery or biopsy. In general, patients have an excellent outcome after appropriate therapy.
Cholesteatoma; It can also be used to treat patients with inadequate conductive hearing from previous middle ear surgery. Stapes implant The stapesplasty prosthesis ...
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.
