A double-layer fascial graft effectively reconstructs the anterior skull base after tumor removal, preventing complications like cerebrospinal fluid leaks and infections. This method is simple and effective for both benign and malignant tumors.

Area of Science:

  • Neurosurgery
  • Oncology
  • Plastic Surgery

Background:

  • Anterior skull base reconstruction is critical after oncological resections.
  • Various techniques exist, but optimal methods for preventing complications remain a focus.

Purpose of the Study:

  • To present a refined method for anterior skull base reconstruction.
  • To evaluate the efficacy of a double-layer fascia lata graft in preventing complications.

Main Methods:

  • Retrospective study of 109 patients undergoing 120 anterior skull base resections.
  • Utilized double-layer fascia lata grafts for large defects, with other grafts/flaps for specific bone or orbital involvements.
  • Pericranial flaps were used to prevent osteoradionecrosis when radiotherapy was planned.

Role of Diffusion MRI Tractography in Endoscopic Endonasal Skull Base Surgery

Published on: July 5, 2021

Main Results:

  • The overall incidence of cerebrospinal fluid leak, intracranial infection, and tension pneumocephalus was 5%.
  • Histopathological analysis of reoperated grafts showed successful integration and vascularization.
  • A double-layer fascial graft alone proved sufficient for preventing major complications.

Conclusions:

  • A double-layer fascial graft is adequate for preventing cerebrospinal fluid leak, meningitis, tension pneumocephalus, and brain herniation.
  • The described method offers a simple and effective approach for anterior skull base reconstruction post-tumor resection.
