Endoscopic Endonasal Skull Base Repair

How Endoscopic Endonasal Skull Base Repair is performed

This procedure is often performed after the leak point is identified. Free mucosal grafts or vascularized nasal septum flaps can be selected as repair materials depending on the individual. Typically, the nasal cavity and sinuses are accessed through a nasal endoscope to expose the skull base defect, clean the edges, and prepare the recipient area. Autologous fascia/fat or artificial dural substitutes are placed in layers, and biological adhesives are used for coverage. If applicable, the pedicled nasal septum flap is used for reinforcement and nasal cavity support and fixation. Postoperative monitoring includes cerebrospinal fluid leakage, intracranial pressure, and signs of infection. The goal is to stably close the leak and promote mucosal healing. The above is general health information, not medical advice; specific information should be based on specialist evaluation and hospital protocols.
