Repositioning of a Traumatically Displaced Globe With Maxillary Antrostomy: Review of the Literature and Treatment Recommendations

Traumatic prolapse of the globe into the anterior cranial fossa: a case report

“…The increased intraorbital pressure causes the orbital bones to break or buckle at their weakest point. This weakest point is most commonly the posterior aspect of the orbital floor, medial to the infraorbital canal and the lamina papyracea of the ethmoid bone [4]. However, blowout fractures of the orbital roof are rarely seen.…”

“…Most researchers have agreed that the dislocated globe should be replaced into the orbital cavity as soon as possible [4,11,12]. Avulsion of the optic nerve and its blood supply is the most common mechanism producing total loss of vision in an intact, severely displaced globe [11].…”

“…Treatment delays may increase the risk of complications such as edema and strain on adnexal structures, especially in the optic nerve and central retinal artery, and this risk increases with time. A twisted or stretched retinal artery may damage the blood supply of the optic nerve, increasing the probability of irreversible vision loss [3,4,11]. Besides, the variability of visual outcomes also depends on the degree to which the optic nerve is distorted [13].…”

Immediate Surgical Management of Traumatic Dislocation of the Eye Globe into the Maxillary Sinus: Report of a Rare Case and Literature Review

“…[23][24][25][26][27] Globe dislocation into maxillary sinus 19 cases. 1,3,6,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] We found 19 cases of globe dislocation into the maxillary sinus summarized in ►Table 1 as follows: One was enucleated 2 months after misdiagnosis as traumatic enucleation. 32 Seven were documented no vision or no light perception.…”

“…27 Although controversy exists regarding the specific surgical and medical management of grossly displaced globes, most investigators have agreed that every attempt should be made to anatomically reposition a displaced globe within the orbital pyramid as soon as possible. 42 Treatment delays increase the risk of complications as edema and strain on the optic nerve and central retinal artery increase with time. The period that the central retinal artery is twisted or stretched further compromises the blood supply to the optic nerve, increasing the probability of irreversible vision loss.…”
