Case description

An attic cholesteatoma is defined as an epidermoid cyst found in the attic. This is differentiated from an infected retraction pocket of the pars tensa or a retraction pocket cholesteatoma. CSF otorrhea occurs only if a perforation in the eardrum or a defect in the external ear canal is present. This is often the case when the leakage results from trauma or previous ear surgery. However, in the absence of such a defect, the fluid flows down the eustachian tube and manifests as a clear rhinorrhea. In this situation, it must be differentiated from a spinal fluid leak from other areas of the skull base, such as the sinuses. The reverse is also important to remember; just because the leak is through the nose does not mean that an otologic source is not a possibility.
