    • otoscopy should includes inspection of the external ear and pinna INSPECT THE EXTERNAL MEATUS --discharge,blood or pus -masses -on insertion of speculum inspect the canal -skin -discharge -swelling -wax OTOSCOPY POSITION pt should be positioned e the head flexed laterally away from the examiner the external auditory canal has a bend which normally restricts the examiner,s view the pinna of the ear to be examined is held firmly and gently pulled upwards and backwards to straighten the canal using the hand not holding the otoscope HOLDING THE INSTRUMENT otoscope is held in the same hand as the ear being examined the speculum should be as wide as possible to comforttably fit into the ear canal holding the otoscope (like a pen) horizontally provides a secure cradle for the instrument the curled fingers can rest against the cheek and the handle will not catch the shoulder (as it may if held vertically) in addition this position will help protect against accidently pushing too deeply into the outer ear TYMPANIC MEMBRANE inspect the tympanic membrane identify the normal structure any insignificant variation in normal appearance report ur findings to examiner

    • Name some drugs which when ingested during pregnancy would cause this condition
    • Microtia

    • How will you manage this condition ?
    • Aural seroma
    • Needle aspiration with application of compression dressing to prevent reaccumulation.

    • Why is this external auditory canal narrow ?
    • What could be the cause ?
    • What could be the clinical problems faced by the patient ?
    • What surgery should be performed in this patient ?
    • Exostosis of external auditory canal.
    • It is common in swimmers.
    • These patients have conductive deafness, cerumen impaction.
    • Cerumen impaction is caused by abnormal self cleansing mechanism of the skin lining external canal in these patients.
