BACKGROUND Since the introduction of fourth- and fifth-generation silicone gel implants, manufacturers have conducted several prospective, multicenter trials to examine their safety and efficacy. However, these studies were not standardized with regard to surgeon skill, pocket placement, operative technique, adjunct therapies, or postoperative management. OBJECTIVE The purpose of this study w...

We present a new method of treatment for nasal valve dysfunction caused by insufficiency or stenosis in a patient who refused open septum revision despite a significant degree of septum deviation. The Anterior Spreader Flap (ASF) technique was suggested as an alternative to open nasal septum revision and was performed under local anesthesia. Computational fluid dynamics (CFD) tests were perform...

OBJECTIVES We evaluate the long-term surgical and hearing results using a canal wall down mastoidectomy technique followed by cavities obliteration, canal wall reconstruction and ossiculoplasty without staging. METHODS A total of 44 patients between January 2002 and October 2009 were selected and 27 of them were revision cases. Preoperative and postoperative pure tone average (PTA) and air-bo...

During a period of nine years (1982-1991), Pauwels' osteotomy was performed for 38 cases of femoral neck non-:::union:::. 32 led to consolidation with one osteotomy (84%) and 6 failed (3 needed revision (92%), one died and two were lost to follow-up). The length of follow-up was 2-11 years, the average time of non-:::union::: 12 months (ranging from 4 months to 13 years) and the mean patien...

We present a technique for determining certain pairs of qualitative simulation predictions to be mutually contradictory . This leads the simulator to produce more informative outputs, which results in improved performance in reasoning tasks like model revision and diagnosis .

background: a rare and devastating complication following anterior cruciate ligament (acl) revision reconstruction is femoral fracture.    case presentation: a 35-year old male soccer player with a history of acl tear from the previous year ago, who underwent arthroscopic acl reconstruction and functioned well until another similar injury caused acl re-rupture. revision of acl reconstruction wa...
