This study introduces a simpler osteoplastic bone flap technique as an alternative to orbitozygomatic (OZ) craniotomy. This novel approach offers improved surgical access and better patient outcomes, including enhanced cosmesis.

Area of Science:

  • Neurosurgery
  • Surgical Techniques
  • Craniotomy

Background:

  • Standard orbitozygomatic (OZ) craniotomy is a common neurosurgical approach.
  • This technique involves zygoma removal, potentially leading to complications.
  • A simpler alternative is sought to improve surgical outcomes.

Purpose of the Study:

  • To present a novel one-piece osteoplastic bone flap technique.
  • To evaluate its efficacy as an alternative to standard OZ craniotomy.
  • To highlight its advantages in neurosurgical procedures.

Main Methods:

  • Development of a one-piece osteoplastic bone flap incorporating frontal, temporal, and lateral orbital rim.
  • Cadaveric dissection of 14 sites in seven heads for initial evaluation.

  • Clinical application in over 200 patients with diverse pathological lesions.

    • Main Results:

    • The technique simplifies the craniotomy by obviating zygoma removal.
    • It provides comparable surgical view and advantages to standard OZ craniotomy.
    • Benefits include avoidance of temporalis muscle atrophy, improved bone union, and decreased infection risk.

    Conclusions:

    • The osteoplastic bone flap technique is a technically simpler and effective alternative to OZ craniotomy.
    • It offers improved long-term cosmesis and warrants consideration in neurosurgery.
    • This approach enhances patient outcomes and surgical feasibility.
