Hearing aid dermatitis.

M Marshall, A Guill, R B Odom

    Archives of Dermatology

    Summary
    This summary is machine-generated.

    Allergic contact dermatitis from hearing aids was caused by methyl methacrylate monomer. Modifying the resin through heat curing reduced residual monomer, resolving the allergic reaction.

    Area of Science:

    • Dermatology
    • Otolaryngology
    • Materials Science

    Background:

    • Hearing aids are common assistive devices.
    • Contact dermatitis can arise from medical devices.
    • Allergens in device materials pose a risk.

    Observation:

    • A patient developed allergic eczematous contact dermatitis.
    • The dermatitis affected the external auditory canals and ears.
    • The patient wore bilateral "in-the-ear" hearing aids.

    Findings:

    • Patch testing identified methyl methacrylate monomer as the allergen.
    • Increased polymerization via heat curling reduced residual monomer.
    • This modification alleviated the patient's dermatitis.

    Implications:

    • Methyl methacrylate is a potential allergen in hearing aids.
    • Heat curing can improve hearing aid biocompatibility.
    • This highlights the importance of material assessment in medical devices.
