Free-flap reconstructions offer superior outcomes for skull base defects, demonstrating better wound healing and fewer complications than pedicled flaps. Microvascular free-tissue transfer is recommended for moderate to large cranial base reconstructions.

Area of Science:

  • Plastic Surgery
  • Neurosurgery
  • Craniofacial Reconstruction

Background:

  • Skull base defects pose significant reconstruction challenges.
  • Traditional methods include pericranial flaps and pedicled myocutaneous flaps.

Purpose of the Study:

  • To compare the efficacy of local, pedicled, and free-flap reconstructions for skull base defects.
  • To identify the safest and most economical reconstruction method.

Main Methods:

  • Retrospective analysis of 90 skull base defect reconstructions over 10 years.
  • Comparison of outcomes between pericranial, pedicled myocutaneous, and free-flap techniques.

Main Results:

  • Pericranial flaps provided reliable dural sealing.

  • Free-flap reconstructions showed higher uncomplicated primary wound healing (95% vs. 62.5%).
  • Free flaps had significantly lower rates of flap loss (0%), CSF leak (5%), meningitis, and abscess (0%).

    • Conclusions:

    • Microvascular free-tissue transfer is the safest and most economical option for moderate to large composite skull base defects.
    • Free-flap reconstruction offers superior outcomes compared to pedicled myocutaneous flaps.
