What is the proper way to straighten out the ear canal in adults?

• A. Pull down and back
• B. Pull up and back
• C. Turn side to side
• D. Twist the ear

Answer: (B)

To inspect the ear canal with an otoscope, you need to straighten the canal so you have a clear, direct path to the tympanic membrane. In adults, pulling the pinna up and back accomplishes this by aligning the external auditory canal, making visualization easier and reducing pressure or discomfort. The angle of the canal in adults benefits from this upward and backward traction, whereas pulling down and back is the technique used for young children because their canal orientation differs. Turning the ear to the side or twisting it does not straighten the canal and can blur the view or irritate the ear. Gently exert the upward and backward pull to achieve a straightened canal for examination.
