Extensive Cholesteatomas: Presentation, Complications and Management Strategy

AbstractTo document the clinical presentation, complications, management strategy and post-operative outcomes of extensive cholesteatomas. Cholesteatoma is a well demarcated cystic lesion derived from an abnormal growth of keratinizing squamous epithelium in the temporal bone. Cholesteatomas commonly involve the middle ear, epitympanum, mastoid antrum and air cells and can remain within these confines for a considerable period. Bony erosion is present confined to ossicular chain and scutum initially, but as the cholesteatoma expands, erosion of the otic capsule, fallopian canal and tegmen can occur. Erosion of the tegmen tymapani or tegmen mastoideum may lead to development of a brain hernia or cerebrospinal fluid leakage. Invasion of jugular bulb, sigmoid sinus, internal carotid artery are noticed in extensive cholesteatoma and are quite challenging and requires expertise. Neurosurgical intervention should be considered along with the otological management in the same sitting in all possible cases. A retrospective review of 12 patients were carried out to assess the clinical presentation, complications, surgical management and postoperative outcomes of extensive cholesteatomas presenting at our centre between January 2017 and December 2019. CT or MRI findings, extent of cholesteatoma intra-operatively along with the status of major neurovascular structures and disease clearance, and the post-operative outcomes including morbidity and mortality were noted. All patients underw...
