When a patient presents with ear canal dermatitis and wears hearing aids, patch testing for (meth)acrylates relevant to their specific device type should be considered, as sensitization profiles differ across mould types.
Identifying device-specific (meth)acrylate sensitization profiles enables more targeted patch-testing protocols and may guide material selection during hearing aid fitting to reduce allergic contact dermatitis in patients.
- 01Allergic contact dermatitis (ACD) from hearing aid ear moulds is linked to (meth)acrylate chemicals used in their manufacture.
- 02Sensitization profiles — the specific (meth)acrylates triggering reactions — vary by hearing aid device type.
- 03Clinicians should consider device type when selecting patch-test panels for suspected hearing aid ACD.
- 04Findings support the need for device-specific material transparency from hearing aid manufacturers.
Different hearing aid ear mould device types produce different (meth)acrylate sensitization profiles in patients with allergic contact dermatitis.
