Endoscopic Orbital Decompression Part 2 of 3

Indications:

• Proptosis
• Corneal exposure from Grave’s 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
