What should you know about otoscope for medical students?

An otoscope combines illumination, magnification and a viewing tip to examine the external ear canal and tympanic membrane. A useful observation describes the canal, wax or discharge, the membrane’s colour and position, visible landmarks, and whether the view is complete. Findings should be interpreted with symptoms and examination context; a red membrane alone does not establish a diagnosis. Review the general Otoscope explanation for device basics.

Check the light, choose an appropriate clean tip and explain the examination. Seat the patient comfortably, stabilise the head and use the correct pinna movement for age. Advance only under direct vision, without force, and compare sides when appropriate. Record what was seen and what could not be seen. Stop for significant pain, bleeding or resistance, and ask a supervisor to reassess. Human consultation pathways include Child Health Consultation and GP Consultation.

Seek senior review for sudden hearing loss, severe pain, marked canal swelling, bleeding, purulent discharge, a suspected foreign body, trauma or a non-visible eardrum when the clinical concern remains high. Escalate urgently for neurological symptoms, severe vertigo, facial weakness or a rapidly unwell patient. Do not label an uncertain finding when the view is incomplete.

Ask how to improve patient positioning, which landmarks should be documented, when pneumatic assessment is appropriate in your setting, and which appearances require immediate senior input. Request feedback on technique rather than relying on a single image or impression.
