Endoscopic Reconstruction of the Anterior Skull Base using a Pedicled Nasoseptal Flap through the Superior Meatus

Key Points

• To evaluate the effectiveness of utilizing a pedicled nasoseptal flap for reconstructing the anterior skull base after tumor removal.
• Conducted endoscopic surgery on a 17-year-old male with suspected meningioma.
• Utilized a Draf IIb approach to remove the right frontal beak and the tumor.
• Employed a pedicled nasoseptal flap with the posterior nasal artery as the blood supply for reconstruction.
• Maintained olfactory mucosa by using the superior meatus for flap placement.
• No signs of recurrence or cerebrospinal fluid leaks observed after 1 year and 6 months post-surgery.
• Surgery minimized impact on the patient's sense of smell, as the olfactory mucosa was preserved.
