Abstract
Chronic otitis media, with or without cholesteatoma, is one of the more common in-dications for performing a mastoidectomy. Mastoidectomy permits access to remove cholesteatoma matrix or diseased air cells in chronic otitis media. Mastoidectomy is one of the key steps in placing a cochlear implant. Here a mastoidectomy allows the surgeon access to the middle ear through the facial recess. A complete mastoidectomy is not necessary; therefore, the term anterior mastoidectomy is often used (anterior to the sigmoid sinus). A mastoidectomy is often an initial step in lateral skull base surgery for tumours involving the lateral skull base, including vestibular schwannomas, meningiomas, temporal bone paragangliomas (glomus tumours), and epidermoids or repair of CSF leaks arising from the temporal bone.
