What to know about an iPhone otoscope

An otoscope uses light and magnification to help view the ear canal and eardrum. An iPhone attachment may add a camera so an image or video can be seen and shared. The view can be limited by earwax, a narrow canal, movement, poor lighting, or an attachment that does not fit correctly. A picture may not show the full ear or reveal how the eardrum moves.

Ear pain, blocked hearing, discharge, fever, or balance symptoms can have different causes. An image alone may not distinguish infection, irritation, wax, a foreign object, or a problem deeper in the ear. Children may also move suddenly, making insertion unsafe.

Do not push an iPhone otoscope or any object into the ear canal, especially in a child. Stop if there is pain, resistance, bleeding, dizziness, or coughing. Avoid trying to remove deeply lodged wax or a foreign object with the device. Clean the attachment as directed and do not share it without appropriate cleaning.

Use the image as information to discuss with a clinician, not as a reason to start leftover drops or antibiotics. A GP consultation can include symptom history and an examination; for a child, a child health consultation may be more suitable. Bring the device or image if a clinician asks to see it, while remembering that direct examination may still be needed.

Arrange prompt assessment for severe ear pain, new hearing loss, ear discharge, bleeding, fever, swelling behind the ear, or a suspected foreign object. Seek urgent help for severe dizziness, facial weakness, confusion, or a serious injury. For babies and young children, persistent crying, poor feeding, or marked sleepiness with ear symptoms warrants medical advice.

Ask whether the image is clear enough to be useful, whether the ear canal and eardrum can be examined directly, and whether wax or infection is present. Ask which drops are suitable, whether hearing should be checked, and what changes should prompt a follow-up visit.
