Periorbital Trauma: A New Classification.

Overlooked injured structures in periorbital trauma could lead to aesthetic and functional deficits. As trauma may affect superficial, middle, and deep components, meticulous survey guided by a structured periorbital trauma classification is needed for proper management. Thus, a new classification for periorbital trauma is proposed to serve this purpose.

Minimizing the Submandibular Incision in Endoscopic Subcondylar Fracture Repair.

Endoscope-assisted treatment of mandibular condylar fractures is an evolving surgical technique of this controversial subject. The approach is performed through an intraoral and additional submandibular incision. This study presents a technique for minimizing the length of the optional submandibular incision.

Onlay bone graft maintenance using guided bone regeneration, platelet rich plasma, and their combination.

Onlay bone grafts have a bad reputation of resorption with loss of contour and volume. Rigid fixation reduces the incidence of resorption but does not prevent it. Literature shows reduction of resorption by applying guided bone regeneration (GBR) barriers and platelet-rich plasma (PRP).

Platelet-rich plasma versus platelet-poor plasma in the management of chronic diabetic foot ulcers: a comparative study.

Non healing diabetic foot ulcers and the resulting potential amputations present significant costs to the health care system and reduce patient quality of life. The goal of diabetic foot ulcer treatment is to obtain wound closure as expeditiously as possible. The use of platelet-rich plasma (PRP) to enhance wound healing has increased dramatically over the last decade.

A modification of the transverse forked flap to allow three-dimensional columella reconstruction.

The original transverse forked flap is effective in reconstructing the anterior wall of columella in a single stage without leaving a noticeable secondary deformity. A modification was done to allow reconstruction of the lateral walls of columella in addition. This three-dimensional reconstruction will provide enough coverage for a cartilage graft if used.

Guided bone regeneration at the donor site of iliac bone grafts for future use as autogenous grafts.

Background: Autogenous bone grafting is considered the standard in management of bony defects but has some disadvantages, including limited source of graft material, especially in children. This study represents an attempt to regenerate bone at the donor site of iliac bone grafts using the guided bone regeneration principle for future use in multistage bone reconstruction by grafting.

Methods: Critical size defects were created in 24 iliac bones of 12 skeletally mature New Zealand White rabbits.

Role of guided bone regeneration principle in preventing fibrous healing in distraction osteogenesis at high speed: experimental study in rabbit mandibles.

The formation of fibrous tissues at the distraction gap may result from the accumulation of rapidly migrating fibroblasts at the site of an osteotomy, especially when distraction is rapid. Addition of osteopromotive membranes could theoretically prevent fibroblasts from entering the distraction gap, allowing the osteotomy site to be filled with only osteogenic cells. This study is an attempt to achieve a rapid successful distraction without fibrosis through the use of collagen membranes.
