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...

BACKGROUND AND AIM To assess the success rate of implants placed in atrophic ridges, regenerated by means of block bone grafts harvested from iliac crest, calvaria or intraoral donor sites (mandibular ramus, chin). METHODS AND MATERIALS A systematic review of all prospective and retrospective studies analyzing the success rate of implants placed simultaneously or as a second surgery following...

BACKGROUND Incisional hernias occur frequently after abdominal surgery and can cause serious complications. The choice of a type of open operative repair is controversial. Determining the type of open operative repair is controversial, as the recurrence rate may be as high as 54%. OBJECTIVES To identify the best available open operative techniques for incisional hernias. SEARCH STRATEGY Ele...

BACKGROUND We report our results after 100 urethroplasties for the treatment of urethral stricture both at the bulbar and penile urethra, using different techniques. METHODS 100 patients with the diagnosis of anterior urethral stricture, that were submitted for urethroplasty in the period 1997-2007. Of them, 57 treated by end to end urethroplasty. 4 patients underwent augmented free graft ana...

The aim of the present retrospective chart review was to determine the relationship between nonvascularized osseous graft remodeling and the three-dimensional (3D) features of grafts and recipient sites, the anatomical recipient regions and different graft sources. 32 iliac crest or chin grafts were onlay-positioned in the mandible or maxilla of 14 patients. CT scans, taken before implant posit...

This study evaluated the effect of retentive areas on onlay preparations on the dimensional alterations in condensation and addition silicone materials. A standard model with an onlay preparation was made. Each impression material was used through the double or simultaneous impression technique (n=25), resulting in a hundred impressions of the same model. Impressions were poured with type IV de...

OBJECTIVE To assess the use of tunica vaginalis graft plus onlay preputial island flap in urethral reconstructive surgery in rabbits through histopathology. MATERIAL AND METHODS We developed an experimental model of urethroplasty that resembles one-stage complex hypospadias surgery with divided urethral plate. The tunica vaginalis graft is dorsally placed to recreate the urethral plate and th...

BACKGROUND Asians with short nose lack the cartilage needed to extend the length of the nose. A rhinoplasty technique using lower lateral cartilage (LLC) repositioning and ear cartilage grafting allows for sufficient nasal lengthening and nasal tip mobility in the correction of short nose in Asians. METHODS Short nose was classified into 3 subtypes: type I, II, or III. During LLC repositionin...

The aim of this study was to assess the nostril symmetry following primary cleft rhinoplasty done with either a dorsal onlay or columellar strut graft in patients with non-syndromic complete unilateral cleft lip and palate. In this retrospective study 30 consecutive patients treated with autogenous or alloplastic dorsal onlay grafts and 30 consecutive patients treated with autogenous or allopla...
