A craniotomy for the repair of a dural or cerebrospinal fluid (CSF) leak is a surgical procedure aimed at addressing leaks that may occur from the nose, known as rhinorrhea, or from the external auditory canal, referred to as otorrhea. These leaks can arise due to trauma or as complications following surgical interventions. The procedure involves a detailed approach where imaging studies, which are separately reportable, are conducted to accurately identify the location of the CSF leak. During the surgery, an incision is made on the skull at the identified site of the leak, allowing for the exposure of the skull. Burr holes are drilled into the skull, and a saw is utilized to connect these holes, creating a bone flap that can be lifted to access the underlying dura mater. Once the dura is exposed, the surgeon locates the tear and repairs it using sutures, fibrin glue, or a dural patch, ensuring the integrity of the dura is restored. After the repair, the bone flap is repositioned and secured in place with sutures, wire, or miniplates and screws. Finally, the soft tissue and skin are meticulously closed in layers to promote proper healing and recovery.
