Abstract

The realization of customized earing plugs and earmolds for hearing aids requires an impression of the external auditory canal to obtain a siliconized mold. Silicone used for ear impressions is known to be safe and inert but deposition of silicone in the middle ear can middle and inner ear damages. We present a case of accidental injection of silicone in the middle ear and the Eustachian tube resulting in an erosion of the carotid canal. Laryngoscope, 133:3358-3360, 2023.
