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.
