BACKGROUND With the increasing use of hydroxyapatite orbital implants, the complication of exposure has become apparent to oculoplastic surgeons. Many kinds of patch grafts, such as sclera, dermis, and hard palate mucosa, have been used to cover exposed hydroxyapatite implants with inconsistent results. In this study, the authors use a newly developed technique, autogenous retroauricular myoper...

purpose: to determine the efficacy of primary placement of a titanium sleeve and peg on hydroxyapatite (ha) orbital implants. methods: this retrospective non-comparative interventional case series was performed on 34 patients undergoing enucleation. a standard enucleation technique with primary ha implantation was performed, in which titanium sleeve and peg were placed primarily during the init...

Reconstruction materials and techniques for the base of the skull have undergone rapid developments and differentiation in recent years. While mostly autotransplants, collagens or resorbable alloplastic materials are preferred for duraplasties, pronounced organ-specific differences can be observed in the reconstruction of hard tissues. The use of polymethylmethacryl bone cement, once wide-sprea...

Two case reports are used to illustrate the signs and symptoms, complications and treatments of chronic socket inflammation due to intraorbital implants. The ophthalmic examination, surgeries and treatments are documented. Two anophthalmic cases that underwent enucleation and multiple orbital surgeries to enhance the anophthalmic socket volume developed pain, intense discharge and contracted ca...

The high sensitivity of CT in detecting metallic orbital foreign bodies has been previously described [1-6] . While there has been some success in detecting glass fragments , detecting intraorbital foreign bodies made of wood has been very unsatisfactory [1, 2, 69]. Plastic orbital implants are easily recognized on CT as high-attenuation-value images [6, 7]. This report presents two cases of pl...

THIs implant was developed with the object ofincreasing the degree ofmovement obtained with the Allen type ofburied orbital implant. The satisfactory way in which these implants are retained in the orbit is demonstrated by the large number which have now more than fulfilled the 2-year follow-up period suggested by Choyce (1952). The retention of the magnetic form of implant appears to be as goo...

BACKGROUND Macular edema is a common complication of uveitis and represents a therapeutic challenge, especially in children. Recently, intravitreal dexamethasone implants have been shown to decrease intraocular inflammation and to control uveitic macular edema in patients with non-infectious intermediate or posterior uveitis. FINDINGS An 11-year-old boy with bilateral granulomatous idiopathic...

OBJECTIVE To assess the effects of hydroxyapatite cement (HAC) on the developing feline craniofacial skeleton. DESIGN Fronto-orbital craniotomies were performed on 14 kittens and reconstructed by autograft or HAC. By design, animals in which the craniofacial skeleton was reconstructed with HAC also underwent obliteration of the left frontal sinus. After achievement of skeletal maturity, anima...

OBJECTIVE To evaluate the success of the temporoparietal fascial flap (TPFF) in the primary or secondary reconstruction of difficult orbital defects and to review the surgical techniques. DESIGN Retrospective analysis. SETTING Tertiary medical center. PATIENTS Nine patients with diverse orbital cavity or periorbital soft tissue and bony defects due to trauma, benign or malignant neoplasms...

BACKGROUND The surgical placement of orbital implants for eviscerations, enucleations, and secondary implantations can cause severe postoperative pain that may not be relieved with high doses of narcotics. We analyzed the effectiveness of a method for postoperative pain control in orbital implant surgery using an orbital epidural pain catheter connected to a patient-controlled analgesia bupivac...
