“…Extra caution should be taken in the presence of risk factors such as tympanostomy tubes, tympanic membrane perforations, and retraction pockets, and when the patient has a history of previous surgery, such as mastoidectomy [1] . The first case report was published in 1983 [6] , and a literature search revealed 40 similar cases published in English, varying only in external or also middle ear involvement [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] . Table 1 provides an overview of those 34 cases in the literature with middle ear involvement and for whom the respective (surgical) removal procedures were described.…”

“…All of these relatively acute symptoms may be considered alarming, and referral would therefore be indicated. Notably, in cases of delayed presentation, symptoms such as perforation, persistent discharge, and conductive hearing loss may mimic chronic otitis media (n=4) [10,11] .…”

“…This is pivotal in the presence of risk factors because the molding material can flow with relative ease into the hypotympanum, mesotympanum, and even the Eustachian tube [2,5,6,10,13] .…”

CASE PRESENTATIONS Case 1Our first case is a 7-year-old girl with bilateral grommets who underwent earplug adjustment for swimming lessons. Upon introduction of the silicone material, the patient immediately complained of otalgia, and the audiology assistant realized she had forgotten to apply a cotton ball before introducing the silicone impression material. The girl was referred to our center; orange silicone material was observed in both ears. Importantly, the silicone material had caused hearing loss and immediate pain, but no other symptoms. It was not yet clear how deeply the material protruded into the (middle) ear.A high-resolution computed tomography (CT) scan was then performed in order to evaluate the protrusion of the material. The CT scan illustrated that on both sides, the external meatus was obstructed, and the material reached the tympanic membrane without protrusion into the middle ear. After informed consent was obtained, the silicone material was removed without complications. Otoscopy confirmed the (pre-existing) grommets to be in the correct position without damage to the tympanic membrane. Case 2Our second case is a 20-year-old male who consulted an audiologist to obtain custom earplugs because of his work in a high-noise environment as a baker. Immediately after injection, the patient suffered from otalgia and hearing loss without vertigo or tinnitus. 345Impression Material in the External and Middle Ear: an Overview of the Literature and a Stepwise Approach for RemovalHere, 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.
