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
