Step-by-step explanation:
The correct option for the procedure used to insert PE tubes in the eardrum is Myringotomy.
A myringotomy is a surgical procedure in which a small incision is made in the eardrum to drain fluid or release pressure from the middle ear. During this procedure, the PE tube is inserted into the incision to keep it open and allow proper ventilation of the middle ear.
