Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Cholesteatoma is a destructive lesion that progressively expands in the middle ear, mastoid or petrous bone and leads to destruction of the nearby structures. Erosion, which is caused by bone resorption of the ossicular chain and otic capsule, may cause hearing loss, vestibular dysfunction, facial paralysis and intracranial manifestations

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cholesteatoma has three Classical forms: (1) Congenital, primary or genuine cholesteatoma: occurs behind an intact tympanic membrane. Primary acquired cholesteatoma: looks like a limited diverticulum of the pars flaccida with little or no history of otorrhea. Secondary acquired cholesteatoma: develops with posterosuperior perforations in eardrum and expansion of the disease process into the antrum, mastoid, attic and middle ear. Granulation tissue, polyps and foul- smelling otorrhea are common findings in this type

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with cholesteatoma

Patients with cholesteatoma in one ear that will compared with the other healthy one.

Multislice computed tomography temporal bone

Intervention Type RADIATION

Patients with cholesteatoma will undergo multislice computed tomography (MSCT) temporal bone images. Then The Tegmen level will be determined and compared with the other normal ear at the same patient
