context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...

The case is presented of a 12-year old boy who sustained severe penetrating ocular trauma while playing on a domestic trampoline. A main spring broke under tension and the hook had struck the eye at high velocity and penetrated the sclera. Primary repair was undertaken but on review it became apparent the eye could not be salvaged. Evisceration was carried out and an orbital implant was placed....

PURPOSE To investigate microbiologic trends and role of biofilm on periorbital biomaterials surgically explanted for recalcitrant infection. METHODS A search of the Bascom Palmer Eye Institute, University of Miami Miller School of Medicine microbiology laboratory electronic database was conducted from 1980 to 2010. Culture results were analyzed from submitted periorbital biomaterials explante...

INTRODUCTION Reconstruction of cranial defects is an essential component of skull base surgery as it aids in restoring functionality, providing coverage of intradural structures, and achieving optimal cosmesis. In acoustic neuroma surgery, tumor removal and subsequent reconstruction of the skull base defect are equally important elements. All three approaches utilized in acoustic neuroma surger...

To investigate the trend of restoration postoperative eye movements after orbital blowout fractures by analyzing percentage Hess area ratio (HAR%). This was a retrospective study patients who underwent blow out reconstruction surgery within 28-days post injury. Eye were measured preoperatively and 3, 6, 12 months operatively chart. Orbital classified into three shapes: trap-door fracture with m...

Facial prostheses aim to restore the appearance, contours, and esthetics of the face while consequently enhancing patients' self-esteem and reintegration into social life. Restoring unilateral missing ocular and orbital tissues is a challenging task that requires great skill from the clinician (anaplastologist) to accurately mimic the opposing natural tissues. Bilateral defects present addition...

The aim of this article is to investigate a retrocaruncular approach for repairing medial orbital wall fractures. A total of 10 fresh cadaver orbits were dissected to investigate a transconjunctival approach to the orbit posterior to the caruncle. Medical records of consecutive patients with medial orbital wall fractures repaired via a retrocaruncular incision at Wilmer Eye Institute over a 10-...

OBJECTIVES Transpositioning of the inferior alveolar nerve to prevent injury in lower jaw has been advocated for orthognathic, pre-prosthetic and for implant placement procedures. However, the concept of infra-orbital nerve repositioning in cases of mid-face fractures remains unexplored. The infraorbital nerve may be involved in trauma to the zygomatic complex which often results in sensory dis...

There is an increasing need to understand the mechanical properties of human orbital fat and its encapsulating connective tissue (OFCT), but such knowledge is not available in the current literature. The purpose of the present study is to examine the mechanical properties of the OFCT. From 5 pairs of 76- to 92-year-old Caucasian human eyes and 33 5- to 7-month-old porcine eyes, 5 human and 11 p...
