What should you know about smartphone otoscope?

This device combines a small camera or lens with a light and a phone display. It may show wax, redness, fluid, discharge, or a view of the eardrum when the angle is suitable. A dark, blurred, or incomplete image does not prove that the ear is normal. Pain, reduced hearing, ringing, dizziness, fever, or discharge also need to be considered alongside any image.

The ear canal is delicate, especially in children. A camera attachment can miss a problem or make an existing injury worse if it is pushed inward. The image can also be difficult to interpret because normal ear canals vary in colour and shape.

Follow the device instructions and use only a clean, correctly sized tip. Rest your hand against the cheek to reduce sudden movement, and stop if there is pain, resistance, bleeding, or distress. Do not use it to dig out wax, remove a foreign object, or place drops based only on what you see. Do not share an uncleaned tip between people.

For a child with ear symptoms, arrange a Child Health Consultation. For an adult, a GP Consultation can combine the image with an examination and hearing history.

Seek prompt medical advice for severe or worsening ear pain, new hearing loss, blood or pus from the ear, a foreign object, marked dizziness, facial weakness, or fever with a child who seems very unwell. Urgent assessment is also sensible after an injury to the ear or head. Do not delay care while trying to obtain a clearer phone image.

Ask whether the canal and eardrum were fully visible, whether wax or infection could explain the symptoms, and whether hearing should be checked. You can also ask if the device is suitable for your age group and what signs should prompt reassessment.
