What is an opening at the head?

An opening at the head typically refers to a surgical procedure or medical condition where an incision or access point is made at the cranial area. This can occur during surgeries such as craniotomy, where part of the skull is removed to access the brain for treatment. It may also refer to openings in the skull due to trauma or congenital conditions. The term can vary in context, so it's important to consider the specific medical situation being discussed.
