Surgical treatment of proptosis bulbi by three-wall orbital decompression

Orbital Decompression in the Endoscopic Age

“…5 Since then, a variety of surgical techniques have been described, in which 1 to 4 of the bony orbital walls are removed to allow decompression of the enlarged orbital contents. [6][7][8][9][10][11] Introduced by Ogura in the 1950s, transantral decompression with removal of the medial and inferior orbital walls was widely adopted by otolaryngologists for treatment of Graves' orbitopathy. Although this approach was effective at reducing proptosis, it resulted in a relatively high incidence of postoperative diplopia (40%-65%) and ocular dystopia (4.5%), or ''setting sun syndrome,'' which occurs when the inferior corneal margin is displaced below the lower eyelid margin.…”

“…[15][16][17] However, the reported incidence of patients who develop new-onset diplopia following endoscopic decompression still ranges from 19% to 45%. 5,10,13,15,[17][18][19][20][21][22][23][24] This wide variation in the reported results likely reflects differences in surgical techniques.…”
