Craniotomy & Repair of Anterior Cranial Fossa Floor

What is a craniotomy & repair of anterior cranial fossa floor?

This brain operation is performed to repair the cranial fossa floor and stop the leaking brain fluid.

A cut is usually made on the head through the hairline from ear to ear. A segment of skull bone is removed to allow access to the cranial fossa floor. The area of the leaking brain fluid is identified.

Another cut is made in your upper thigh. This will allow tissue to be taken which is to be used as donor tissue to repair the leaking area of the cranial fossa floor.

Tissue glue may also be used to assist with the repair of the leaking brain fluid. The skull bone is put back and closed with metal plates and screws.

The cuts are closed with stitches or staples.
