    Transsphenoidal surgery causes temporary and permanent changes in the sinuses and sella. Radiologists should be aware of these findings and potential complications detectable by computed tomography (CT) scans.

    Area of Science:

    • Radiology
    • Neurosurgery
    • Otolaryngology

    Background:

    • Transsphenoidal surgery is a common procedure affecting the paranasal sinuses and sella.
    • Radiologists must be familiar with post-surgical imaging findings.

    Purpose of the Study:

    • To outline the expected imaging changes after transsphenoidal surgery.
    • To highlight complications detectable by computed tomography (CT).

    Main Methods:

    • Review of imaging findings following transsphenoidal surgery.
    • Identification of transient and permanent post-operative changes.
    • Detection of surgical complications using CT.

    Main Results:

    • Transient changes include soft-tissue-density debris in sinuses.

  • Permanent changes include residual packing material.
  • CT can detect complications like bleeding, CSF leaks, pneumocephalus, and compression.

    • Conclusions:

    • Familiarity with transsphenoidal surgery's imaging sequelae is crucial for radiologists.
    • CT is effective in identifying post-operative changes and complications.
    • Residual lesions may persist even after surgery and radiation therapy.
