Granulomatous orbital cellulitis is one of the most common ocular manifestations of granulomatosis with polyangiitis (Wegener's). The process is often refractory to conventional immunosuppressive therapy and requires a more radical treatment approach. However, surgical experience with this type of patients is limited. There have been just a few reported cases of orbital decompression in such patients and many authors have doubted the appropriateness of the procedure, since it is associated with a high risk of potentially fatal complications...

Highly coordinated iron and cobalt nitrides were successfully synthesized via direct chemical reaction between a transition metal and molecular nitrogen at pressures above approximately 30 GPa using a laser-heated diamond anvil cell. The synthesized novel transition metal nitrides were found to crystallize into the NiAs-type or marcasite-type structure. NiAs-type FeN could be quenched at ambient pressure, although it was gradually converted to the ZnS-type structure after the pressure was released. On the other hand, CoN was recovered with ZnS-type structure through a phase transition from NiAs-type structure at approximately a few gigapascals during decompression...

Injury to the peripheral sensory branches of the trigeminal nerve can follow a wide variety of craniofacial injuries. Many patients with facial fractures complain about the symptom of numbness to the distribution of injured nerve, which is indicative of hypoesthesia. Hyperesthesia involving the infraorbital nerve is rare in comparison to hypoesthesia secondary to facial trauma. The authors report on 2 patients with infraorbital nerve hyperesthesia in surgically repaired orbital fracture patients. Surgical decompression of the infraorbital nerve led to rapid resolution of hyperesthesia...

INTRODUCTION: Silent sinus syndrome is an unusual cause of progressive enophthalmos and hypoglobus due to atelectasia of the maxillary sinus associated with osteolysis of the orbital floor. This syndrome is classically idiopathic, but the term is also used to describe traumatic or iatrogenic (surgical orbital decompression) cases. CASE REPORT: We report the case of a 33-year-old man who presented with a left orbital trauma without functional disorder. Computed tomography (CT) scan revealed a nondisplaced fracture of the left orbital floor...

Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves' disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. There is an increased volume of extraocular muscles, orbital connective and adipose tissues. Clinical findings of thyroid-associated ophthalmopathy are soft tissue involvement, eyelid retraction, proptosis, compressive optic neuropathy, and restrictive myopathy...

Geriatric patients (age ≥ 65) are prone to complications after surgery and are at risk for severe thyroid eye disease (TED). In this study, we aim to identify preoperative demographic and TED patterns associated with geriatric patients who underwent decompression surgery, to examine the effect of age on postoperative strabismus rates, and to identify factors that may contribute to postoperative strabismus in the geriatric subgroup. We retrospectively reviewed patients who underwent thyroid-related orbital decompression surgery at the Kellogg Eye Center, University of Michigan, between 1999 and 2014...

Background: Eye prominence is a source of cosmetic "deformity" for many patients not afflicted by Graves. Objectives: To report our experience in using customized orbital decompression for purely aesthetic reason to reduce eye prominence in non-thyroid patients. Methods: Retrospective analysis of patients undergoing cosmetic orbital decompression by one surgeon. Surgical technique included customized graded orbital bony-wall decompression (lateral-wall, basin, medial-wall, posterior-strut) and intraconal fat removal using eyelid crease and/or caruncle incisions...

The literature regarding orbital decompression for thyroid eye disease is vast, spanning multiple specialty areas including neurosurgery, head and neck, maxillofacial and ophthalmic plastic surgery. Although techniques have advanced considerably over the more than 100 years during which this procedure has been performed, the four major approaches remain: transorbital, transcranial, transantral and transnasal. The explosion in literature related to orbital decompression has mostly involved minor technical variations on broader surgical themes...

INTRODUCTION: Surrounded by a variety of structures including the facial sinuses and the brain, the human orbit displays unique anatomical features. It is known that orbital volume correlates with age and sex. The aim of this study was to evaluate sexual dimorphism of orbital volume relative to the size of the skull, and to establish criteria for gender determination. METHODS: Orbital volume was measured from 3D models of the orbits. The volumes were expressed in relation to the centroid size of the skull, to ensure that any sexual dimorphism in orbital volume was not simply due to a difference in skull size...

REVIEW

Although most cases of thyroid eye disease (TED) can be managed medically, some refractory or severe cases are treated surgically with orbital decompression. Due to a lack of randomized controlled trials comparing surgical techniques for orbital decompression, none have been deemed superior. Thus, each case of TED is managed based on patient characteristics and surgeon experience. Surgical considerations include the extent of bony wall removal, the surgical approach, the choice of incision, and the use of fat decompression...
