Cholesteatoma Attic Ct

Ct ct is the modality of choice for diagnostic assessment of cholesteatomas due to its ability to demonstrate the bony anatomy of the temporal bone in exquisite detail. The mass extends superiorly into the attic and appears to have eroded through the tegmentum as well as through the fallopian canal of the facial nerve and perhaps the lateral semicircular canal. The scutum and lateral attic wall were the most common bony erosions in the middle ear bony wall 64 3 and the incus was the most eroded ossicle in the middle ear 88 2.

Cholesteatoma attic ct.

A cholesteatoma is an abnormal skin growth in the middle ear. A discrete soft tissue lesion is seen in middle ear cavity. Often presents with a malodorous ear discharge with associated hearing loss. Ct is required for preoperative planning reconstruction of ossicles if needed and to exclude perforation of the bony tegmen.

The study showed that a high incidence of cholesteatoma in the third decade of life. Upon reaching the posterolateral wall of the attic further expansion of the cholesteatoma is deflected superiorly toward the aditus ad antrum and mastoid antrum. Cholesteatoma is an accumulation of squamous epithelium and keratin debris that usually involves the middle ear and mastoid. As the cholesteatoma fills the aditus ad antrum the adjacent lateral semicircular canal is at risk.

Cholesteatomas appear as regions of soft tissue attenuation exerting mass effect and resulting in bony erosion. This case is a. A cholesteatoma is an abnormal noncancerous skin growth that can develop in the middle section of your ear behind the eardrum. Cholesteatomas are not cancerous as the name may suggest but can cause significant problems because of their erosive and expansile properties.

Here learn about the causes symptoms treatment and complications of a cholesteatoma. The pars flaccida cholesteatoma originates in prussak space and usually extends posteriorly while the pars tensa cholesteatoma originates in the posterior mesotympanum and tends to extend posteromedially. Although benign it may enlarge and invade adjacent bone. It may be a birth defect but it s most commonly caused by repeated.

Case contributed by. Diagnosis is clinical based on history and otoscopic findings. Axial bone window left sided otitis media reaching upto epitympanum and prussack s space and communicating with mastoid antrum with collection in mastoid air cells. Cholesteatoma is a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and or mastoid process.
