in addition to graft clarity, an acceptable refractive error is essential to consider a corneal transplant successful. the most common complication of penetrating keratoplasty (pk) is postkeratoplasty astigmatism which can result in decreased visual acuity, anisometropia, and mono-ocular diplopia. these complications can cause patient dissatisfaction, in spite of a successful transplant. intrao...

OBJECTIVE To examine the effects of rigid plate fixation (RPF) and subsequent removal on craniofacial growth in rabbits. DESIGN Randomized controlled experiment. SUBJECTS Thirty-two 6-week-old male New Zealand white rabbits. INTERVENTIONS Group 1 underwent exposure of the left nasofrontal suture and midzygomatic arch; group 2, RPF of the left nasofrontal suture and midzygomatic arch areas...

Introduction. The two possible justifications for surgery in craniosynostosis are first, to allow room for the growing brain, thus preventing damage to developing neural structures and second, to prevent or correct deformity . There is considerable doubt about the extent to which the first consideration is valid. Objective signs of increased intracranial pressure are rarely seen with a single c...

In an attempt to determine the best method for surgical removal of devitalized small colon lesions, 12 horses underwent a double small colon resection and end-to-end anastomosis. In 4 horses (study 1), an appositional single-layer (APP-1) suture pattern was compared with an inverting 2-layer (INV-2) suture pattern. In 8 horses (study 2), an appositional 2-layer (APP-2) suture pattern was compar...

In periodontal plastic surgery it is increasingly more evident the relavance of the protection of the gingival marginal anatomy through the realization of a conservative flap. Minimizing the recession of the treated tissue. A correct healing always needs to take into account the diameter and type of the suture and the time of removal from the wound.

purpose: to compare the refractive results of penetrating keratoplasty (pk) in two groups of patients with keratoconus undergoing corneal grafting with different amounts of donor-recipient disparity (0.25 and 0.5 mm). methods: as a randomized clinical trial and after performing a complete ocular examination and vitreous length measurement, 30 patients with keratoconus were randomly assigned in ...

BACKGROUND All-soft tissue suture anchors provide advantages of decreased removal of bone and decreased glenoid volume occupied compared with traditional tap or screw-in suture anchors. Previous published data have led to biomechanical concerns with the use of first-generation all-soft suture anchors. PURPOSE/HYPOTHESIS The purpose of this study was to evaluate the load to 2-mm displacement a...

BACKGROUND Purpose and hypothesis: Patellar ligament rupture is a rare disabling pathology requiring a surgical ligament suture protected by a frame. The gold standard is the steel cable, but its rigidity and the necessity of a surgical re-intervention for its removal render it unsatisfactory. The objective of this paper is to quantify the mechanical protection provided by the terylene® in comp...
