What is the incision made from behind the ear across the top of the head that permits examination of the brain?

• A. Bicoronal Incision
• B. Occipitocranial Cut
• C. Coronal Craniotomy
• D. Intermastoid Incision

Answer: (D)

The main idea here is a wide, scalp-sparing approach that gives broad access to the cranial vault. A bicoronal incision starts behind one ear, travels over the vertex of the head, and ends behind the other ear. This creates a large scalp flap that can be reflected to expose the skull for a craniotomy, making it the best match for examining the brain.

The other described approaches don’t fit this description: an incision along the mastoid region (behind the ear) doesn’t extend across the top of the head; a coronal craniotomy refers to the bone opening created by the incision but isn’t itself the incision name; an occipitocranial cut goes from the occipital area and doesn’t traverse the crown.
