objective- this study aimed to evaluate the feasibility of using platelet rich fibrin membrane as a novel on-lay patching biomaterial in canine esophagotomy and its effects on esophageal wound healing. design- experimental study. animals- eight adult mixed breed dogs of both sexes equally allocated to control and treatment groups. procedures- longitudinal incisions measuring 3 cm were made in t...

OBJECTIVES Since the resurgence in the use of buccal mucosa (BM) in substitution urethroplasty in the late 1980s and early 1990s, there has been controversy as to which surgical technique is the most appropriate for its application. METHODS The authors performed an updated literature review. Several centres have published widely on this topic, and the points considered include the use BM in d...

STATEMENT OF PROBLEM Preparation designs and ceramic thicknesses are key factors for the long-term success of minimally invasive premolar partial coverage restorations. However, only limited information is presently available on this topic. PURPOSE The purpose of this in vitro study was to evaluate the fracture resistance and failure modes of ceramic premolar partial coverage restorations wit...

Background Lateral sphenoid encephaloceles present a surgical challenge. These encephaloceles may be difficult to access given their lateral location and proximity to the neural and vascular structures of the sphenoid floor, pterygopalatine fossa, and lateral and superior sphenoid walls. Additionally, many patients have idiopathic intracranial hypertension, increasing the risk of recurrence. Wh...

OBJECTIVE To compare the outcomes of three different urethroplasty techniques (onlay, buccal mucosa, Koyanagi type I) used in the reconstruction of severe hypospadias. PATIENTS AND METHODS Over 10 years (1997-2007), 300 severe hypospadias cases were treated with a mean follow up of 2 years (1-105 months); 203 were operated by the same surgeon of whom 184 completed follow up. Three main techni...

Synthetic onlays that are implanted onto the surface of the cornea have the potential to become an alternative to spectacles and contact lenses for the correction of refractive error. A successful corneal onlay is dependent on development of a biocompatible polymer material that will maintain a healthy cornea after implantation and that will promote growth of corneal epithelial cells over the o...
