    Computed tomography (CT) scanning aids orbital surgeons in diagnosing and planning surgeries by precisely locating orbital lesions. It helps differentiate tumors and track recurrence, improving patient outcomes.

    Area of Science:

    • Ophthalmology
    • Radiology
    • Neurosurgery

    Background:

    • Computed tomography (CT) scanning has become a vital tool for orbital surgeons.
    • Accurate localization of orbital lesions is crucial for effective diagnosis and surgical planning.

    Purpose of the Study:

    • To highlight the role of CT scanning in the diagnosis and management of orbital pathologies.
    • To assess the utility of CT scanning in surgical planning and postoperative follow-up.

    Main Methods:

    • Review of CT scan applications in orbital surgery.
    • Analysis of CT's ability to delineate lesions, assess invasion, and detect recurrence.

    Main Results:

    • CT scanning effectively localizes retrobulbar lesions and distinguishes intraorbital from extraorbital masses.

  • It guides surgical approaches by relating lesions to critical structures like the optic nerve and bony walls.
  • CT can detect intracranial extension and postoperative tumor recurrence, though polytomography may be superior for optic canal invasion.

    • Conclusions:

    • CT scanning significantly enhances orbital surgery by improving diagnostic accuracy and surgical planning.
    • Serial CT scans are recommended for postoperative follow-up to monitor for recurrence and differentiate from inflammation.
