Delayed Onset Diplopia due to Minimal Orbital Floor Fractures 16 Months Previously / 대한이비인후과학회지

Ocular symptoms related to orbital fracture occur immediately after the fracture in most cases. However, authors experienced a delayed onset diplopia occurred 16 months after orbital floor fracture. A 19-year-old man, who had right orbital floor fracture 16 months ago, presented with diplopia of upward gaze. At the time of the fracture, no surgery was performed because the fracture was minimal and there were no particular symptoms. Physical examinations revealed a minor ocular motility restriction of upward gaze, but orbital floor showed no definite interval change on computed tomography. Severe adhesion between the orbital fat tissue and orbital floor was noted intraoperatively and the adhesion was dissected. After the operation, the patient showed remarkable improvement in diplopia and restriction of the ocular motility.

2 Cases of Optic Nerve Decompression of Two Traumatic Optic Neuropathies Using Intranasal Endoscope / 대한이비인후과학회지

Traumatic optic neuropathy is a complication resulting from facial trauma, with an incidence of 2% to 5%. The most widely accepted treatments include observation, high dose steroid, surgical decompression and combination therapy of steroid and surgical treatment. However, there has been no established mode of treatment and there are still debates about what the best treatment should be for the patients with optic canal fracture. We experienced two cases of traumatic optic neuropathies due to intracanalicular fracture of the optic canal after trauma. Surgical decompression was performed using an endoscope int-ranasally one day after injury as required for minimal invasive surgery. We report the results and progression of these two cases.

Reconstruction of Bony Orbit Using Endoscope and Polyethylene with Embedded Titanium for a Patient with Postoperative Enophthalmos / 대한이비인후과학회지

Enophthalmos means displacement of the globe into the bony orbit backward, and usually downward. In post-traumatic enophthalmos, the mechanisms that determine the globe position can be the enlargement of the orbital cavity, the herniation of orbital fat into the maxillary sinus, fat atrophy, loss of ligament support, and scar contracture. It can be reconstructed through several approaches such as transconjunctival, canthotomy, lower eye lid, coronal approach, and by using bone, cartilage, and alloplastic materials. The authors report a case of postoperative enophthalmos reconstructed through subciliary and transnasal endoscopic approaches using porous polyethylene with embedded titanium.
