Daniela Páez Mantilla, Claudio Krstulovic, Manuel Mateos Fernández, Herminio Pérez Garrigues
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...

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...

Bilateral sudden onset hearing loss and vestibular dysfunction due to metastatic carcinoma of the internal auditory canal (IAC) on both sides is an extremely rare occurrence. This is a challenging case in neuro-otology that is difficult to relieve by medical support, and spontaneous compensation by vestibular rehabilitation is minimal. The spread of tumor cells to the cerebrospinal space indicates poor prognosis. We present a patient with stage-III gastric carcinoma who experienced sudden hearing loss and severe imbalance...

OBJECTIVE: Diabetes is the most common glucose level dependent metabolic disorder and studies have shown that hearing impairment can be a long-term subclinical complication. Studies to investigate auditory system involvement in diabetes has focused majorly on the auditory brainstem response (ABR), otoacoustic emission, and basic audiological measures. Hence in the current study, we used speech-evoked ABR (S-ABR) as a tool to see the effect of diabetes on both a transient and sustained response of the auditory brainstem to a conventionally used consonant-vowel (CV) stimuli /da/...
