OBJECTIVE To determine the usefulness of porous high-density polyethylene implants (Medpor) in a variety of facial skeletal deformities and subcutaneous defects, excluding those associated with acute maxillofacial trauma. DESIGN Case series. SETTING Academic tertiary care referral center in Baltimore, Md. PATIENTS Thirty-four patients (age range, 20-74 years) with facial deformities requi...

Magnetoencephalography (MEG) signals are influenced by skull defects. However, there is a lack of evidence of this influence during source reconstruction. Our objectives are to characterize errors in source reconstruction from MEG signals due to ignoring skull defects and to assess the ability of an exact finite element head model to eliminate such errors. A detailed finite element model of the...

A novel artificial bone substitute composed of bioactive MegaGen synthetic bone (MGSB) and hyaluronate (HA) hydrogels was successfully developed for bone tissue engineering applications. HA is known to play important roles in bone regeneration due to its angiogenic and osteoconductive characteristics. Accordingly, HA hydrogel was designed to supply HA continuously for effective bone regeneratio...
