A 30 year old female with absolute glaucoma status post-evisceration developed recurrent orbital implant exposure and scleral melting. We successfully treated the large conjunctiva defect by utilizing secondary implant of dermis fat graft for tissue growth and tension-free conjunctiva closure. The patient was satisfied with the postoperative outcome, and no major complications were observed in ...
Orbital emphysema is usually caused by trauma and fracture of an orbital bone, allowing air to pass from the sinuses into the orbit. Orbital emphysema without any significant trauma is rare. We present a case of a 67-year-old-woman who complained of left exophthalmos without any history of trauma, sneezing, or sinus surgery. Computed tomography scanning showed left orbital emphysema protruding ...
INTRODUCTION In orbital reconstruction, the optimal location of a predefined implant can be planned preoperatively. Surgical results can be assessed intraoperatively or postoperatively. A novel method for quantifying orbital implant position is introduced. The method measures predictability of implant placement: transformation parameters between planned and resulting implant position are quanti...
Repair of orbital bone defects caused by trauma, infection or cancer is a continuous challenge in reconstructive surgery. Few studies have reported the application of tissue engineering for the repair of orbital bone defects in large animal models. Thus, we investigated the effects of tissue-engineered bone enhanced by the human bone morphogenetic protein-2 (BMP2) on the repair of orbital wall ...
We present a case of a 79-year-old man with a non-symptomatic pulsatile proptosis of the left eye. Magnetic resonance imaging revealed a meningocele into the left orbit due to an osseous defect in the orbital roof.
BACKGROUND Mucoceles are slowly expanding cystic lesions with respiratory epithelium containing mucus most commonly affecting the frontal and ethmoidal sinuses. They are caused by obstruction of sinus ostium. Mucoceles exert pressure on the bony boundaries and due to the proximity to the brain and orbit extension to these areas are common. CASE PRESENTATION A case of a frontal mucocele with a...
purpose : to report a patient with orbital pseudotumor masquerading as orbital cellulitis case report : a 42-year-old woman was referred to orbit and oculoplastic clinic with 6 days history of left orbital pain, proptosis, lid edema and fever. clinical finding included severe lid edema, chemosis, conjunctival injection and severe restriction in extraocular motility. she was diagnosed as orbital...
Loss of eye leads to significant psychological trauma which necessitate rehabilitation. Restoring defects with prostheses will uplift status such patients by re-establishing the facial structures and appearance, eventually returning them their normal life. Even though prefabricated orbital are available, lack proper fitting indirectly affect comfort aesthetics. Custom-made prosthesis is still p...
