Endoscopic Orbital Decompression Part 1 of 3

Indications:

  • Proptosis
  • Corneal exposure from Grave‚Äôs orbitopathy

Highlights:

  • Sphenoethmoidectomy to fully expose the lamina papyracea
  • Maxillary antrostomy should be large for adequate exposure of orbital floor
  • Removal of lamina papyracea
  • Incise periorbita from posterior to anterior so that view is not obscured as orbital fat prolapses into nasal cavity

Keep in Mind/Things to Remember:

  • Concurrent lateral decompression may be necessary for additional reduction in proptosis
  • Avoid bone removal in the region of frontal recess so as not to obstruct frontal outflow from prolapsing orbital fat
