Endoscopic skull base surgery requires reliable reconstruction of large defects. New anteriorly pedicled flaps, alongside the nasoseptal flap, offer improved coverage for challenging anterior skull base reconstructions.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Surgical Innovation

Background:

  • Endoscopic skull base surgery creates large defects requiring repair to separate cranial and nasal cavities.
  • The nasoseptal flap is a common method for anterior skull base reconstruction but has limitations for extremely anterior defects.
  • Defects involving the frontal beak, posterior frontal table, and anterior cribiform plate pose reconstruction challenges.

Purpose of the Study:

  • To evaluate the efficacy of anteriorly pedicled flaps for anterior skull base reconstruction.
  • To address the limitations of the nasoseptal flap in reconstructing extensive anterior skull base defects.
  • To expand the reconstructive options for complex skull base defects.

Main Methods:

  • Review of alternative anteriorly pedicled flaps, including bipedicled anterior septal and anteriorly based inferior turbinate flaps.

Coronoid-Temporalis Pedicled Flap for Orbital Floor Defect Reconstruction

Published on: December 5, 2025

  • Exploitation of vascular supply from the anterior septum and lateral nasal wall for flap design.
  • Application of these flaps for reconstruction of frontal beak, posterior frontal table, and anterior cribiform plate defects.

    • Main Results:

    • The nasoseptal flap is limited in reaching extremely anterior skull base defects.
    • Bipedicled anterior septal flaps reliably reconstruct frontal beak and posterior frontal table defects.
    • Anteriorly based inferior turbinate flaps successfully reconstruct anterior defects.
    • Anteriorly pedicled flaps provide vascularized mucosal coverage for various endoscopic skull base regions.

    Conclusions:

    • Anteriorly pedicled flaps are valuable additions to the reconstructive armamentarium for endoscopic skull base surgery.
    • These flaps overcome the limitations of the nasoseptal flap for extensive anterior defects.
    • The described flaps enable comprehensive vascularized mucosal coverage of the anterior skull base.
