Canalolabyrinthine schwannoma is a rare subtype of neuroma. Only 1 case has been described in the literature. We report the clinical case of a 51-year-old Caucasian female with Meniere's disease-like symptoms. Magnetic resonance imaging showed right VIII cranial nerve schwannoma that had different characteristics from the classical described types. The peculiar features of our case of intralabyrithine canalolabyrinthine schwannoma directed the surgeon and radiologist to tailored considerations for follow-up and therapy...

The European Academy of Otology and Neurotology (EAONO) has previously published a consensus document on the definitions and classification of cholesteatoma. It was based on the Delphi consensus methodology involving the broad EAONO membership. At the same time, the Japanese Otological Society (JOS) had been working independently on the "Classification and Staging of Cholesteatoma." EAONO and JOS then decided to collaborate and produce a joint consensus document. The EAONO/JOS joint consensus on "Definitions, Classification and Staging of Middle Ear Cholesteatoma" was formally presented at the 10th International Conference on Cholesteatoma and Ear Surgery in Edinburgh, June 5-8, 2016...

Here, we provide a literature overview of cases with protruding molding material for earplugs or hearing aids and subsequent required treatment, including our own cases. Patients at risk are those with impaired tympanic membranes or who previously underwent otologic surgery. Symptoms such as otalgia, tinnitus, and vertigo are alarming but do not always arise. In case of doubt, a CT scan is of additive value to prepare for adequate surgical removal and to limit potential damage. A stepwise approach for the clinician on how to address these challenging cases is presented, based upon the literature and our own experience...

A cholesteatoma is a relatively common condition within the middle ear cavity, whereas a cholesteatoma of the squamous part of the temporal bone is an exceptionally rare entity. A case of an iatrogenic cholesteatoma located in the squamous part of the temporal bone is presented, which was revealed by an intermittent purulent discharge from an opening above the right ear 20 years after retroauricular myringoplasty. The diagnosis of an iatrogenic cholesteatoma is often made after several years of evolution, sometimes even at the stage of complications...
