Final answer:
The procedure that involves making an incision into the eardrum is known as myringotomy, a term derived from medical prefixes and suffixes.
Step-by-step explanation:
Using knowledge of prefixes and suffixes in medical terminology, a medical assistant should identify the term for a procedure that involves an incision into the eardrum as myringotomy. This term combines the suffix '-otomy', meaning incision or cutting, with the prefix 'myring-', which refers to the membrane of the eardrum, also known as the tympanic membrane. This procedure is often performed to relieve pressure caused by excess fluid in the middle ear, a condition that can result from acute otitis media or chronic inflammation.
