Which term describes buildup of ear wax blocking ear canal?

• A. Nystagmus
• B. Cerumen impaction
• C. Otitis
• D. Retinal detachment

Answer: (B)

This describes a blockage caused by ear wax buildup in the ear canal, known as cerumen impaction. Cerumen, or ear wax, is produced to protect and lubricate the ear; normally it moves out of the canal on its own. When wax accumulates and hardens, it can block the canal, leading to fullness, muffled hearing, and sometimes mild discomfort or tinnitus. It’s treated by softening the wax with drops and then removing it safely with suction or gentle irrigation.

Other terms don’t fit: nystagmus is an involuntary eye movement problem, not related to the ear canal. Otitis refers to an ear infection, which involves inflammation and often pain or discharge rather than a simple wax buildup. Retinal detachment is a serious eye condition affecting the retina, not the ear.
