Abstract:
The successful reconstruction of anterior skull base defects following transcribriform or transsphenoidal surgery is pivotal in mitigating the communication between the external environment and the cranial cavity. This intervention is crucial to prevent potential complications, including cerebrospinal fluid leakage and meningitis. The ideal reconstructive flap should possess sufficient vascularity and be of ample size to adequately cover vital nerves and vessels. Predominantly, the nasoseptal flap is employed for the repair of skull base defects. This flap is vascularized by the posterior division of the sphenopalatine artery, ensuring sufficient coverage of the defects. A significant advantage of the nasoseptal flap is its rotational capability, allowing for mobilization and repositioning to effectively cover the defect. Nonetheless, the rotational tension on the nasoseptal flap running from the nasal cavity to the skull base may affect the distal margin of the flap. Alleviation of this tension can be achieved through the insertion of multiple minuscule incisions in the vertical axis of the flap’s border. This report introduces and elaborates on this technique.
