    TLDR The flap effectively sealed leaks and served as a barrier, with minor complications, for anterior skull base surgery.
    The composite galeal frontalis pericranial flap was designed for anterior skull base surgery to address limitations of the traditional pericranial flap, particularly in providing a barrier between the nasal cavity and brain. This flap was used in 7 operations and featured a narrow pedicle to avoid complications like numbness and skin necrosis. The flap included the supratrochlear arteries but excluded the supraorbital artery, balancing toughness and blood supply. It was effective in sealing cerebrospinal fluid leaks and reconstructing the nasal cavity ceiling, though it was not suitable for massive cranial base defects. Mild complications included glabella depression and temporary visual issues, but the flap avoided numbness and skin necrosis. The study suggested this flap as a viable option for minimally invasive anterior cranial base surgery.
