Managing a long-recurring primary orbital hemangiopericytoma.

Hemangiopericytomas are uncommon vascular neoplasms that originate from the pericytes lining capillaries and postcapillary venules. Few cases of primary orbital hemangiopericytoma have been reported. We present a 61-year-old woman with longstanding, recurrent benign orbital hemangiopericytoma and results of its successful removal.

A novel solution for superficially placed calcium hydroxylapatite (Radiesse) in the inferior eyelid.

Injectable fillers such as calcium hydroxylapatite (Radiesse) have become increasingly prevalent given their availability as an office procedure as well as their satisfying results. Calcium hydroxylapatite is well suited for use along bony structures in the face such as the inferior orbital rim and zygoma. On the other hand, it is not well suited for injection into the soft periorbital tissues and eyelid.

Timing of return to normal activities after orbital floor fracture repair.

Background: Orbital floor fractures are among the most common facial fractures, and patients and surgeons often ask when the patient can resume normal activities after surgical treatment. This study attempted to address this basic issue by examining wound strength and histologic characteristics after orbital floor fracture repair with three commonly used materials.

Methods: Twenty-one female goats were anesthetized under general anesthesia.

Beveled osteotomy with lateral wall advancement and interpositional bone grafting for severe thyroid orbitopathy.

Purpose: To present a new technique for orbital decompressions for patients with severe thyroid orbitopathy that minimizes complications while maximizing the amount of decompression. This method involves advancing the lateral orbital wall in such a way as to promote osseous union and minimize cosmetic deformities.

Methods: This paper represents a case series (42 eyes from 26 patients) of orbital decompressions for severe thyroid related orbitopathy.

Assessment of biomechanics of orbital fracture: a study in goats and implications for oculoplastic surgery in humans.

Purpose: To determine the biophysical characteristics of energy absorption of the various orbital structures and the amount of force/energy required to produce an orbital fracture in goats, and to interpret results in terms of human clinical applicability.

Design: Experimental animal study.

Methods: The energy required to fracture the orbit on direct globe impact was measured.

Improved prosthetic motility with placement of a second coupling PEG.

Purpose: Integrated coupled orbital implants have been shown to improve prosthetic motility over noncoupled orbital implants. Some patients are limited in prosthetic motility despite this coupling for various mechanical and physiological reasons. A common limitation of motility in anophthalmic rehabilitation is forniceal constriction or scarring.
