Bone Repair Process in Defects of Diabetic Rats Filled with Autogenous Bone Graft and Covered with Homogenous Bone Matrix Membrane or Polytetrafluoroethylene Membrane.

Purpose: To analyze the process of repair of bone defects in diabetic rats filled with autogenous bone and covered with membranes of homogenous bone matrix or expanded polytetrafluoroethylene (ePTFE).

Materials And Methods: One hundred twenty male rats were divided into two groups: group 1 (IC), without systemic alterations (control), received an intravenous injection of citrate buffer at 0.01 M, pH 4.

Survival Without Neurological Impairment of a Patient With Rhino-Orbito-Cerebral Zygomycosis.

Rhinocerebral zygomycosis is a rare condition characterized by infection initially in the nose and paranasal sinuses with atypical symptoms consistent with sinusitis. Once established in the nasal sinuses, the infection can easily spread to the orbital region and brain. In the localized form of the infection, the mortality rate is approximately 10%, which increases in the occurrence of orbital involvement and survival in patients of cerebral dissemination is extremely rare.

Bone repair of surgical defects filled with autogenous bone and covered with demineralized bone matrix membrane or polytetrafluoroethylene membrane in rats.

Purpose: The aim of this study was to evaluate the behavior of a demineralized bone matrix membrane and a polytetrafluoroethylene (PTFE) membrane in the process of bone repair of surgical defects filled with autogenous bone in rats.

Materials And Methods: Sixty rats weighing approximately 250 g each were selected and separated into three groups: control group without membrane, demineralized bone matrix membrane group, and PTFE membrane group. Bilaterally, surgical defects of 2 mm in diameter were prepared in the tibiae.

The primary closure approach of dog bite injuries of the nose.

The nose holds an outstanding position on the face, acquiring great importance within the context of facial aesthetics. Because of the functional, psychological, and social aspects of trauma in a society increasingly demanding about aesthetics, treatment institution must reduce, as accurate as possible, the sequelae that hinder social integration. This clinical report relates an immediate nasal reconstruction of a complex animal bite wound.

[Evaluation of palpebral subtarsal approach in surgical treatment of orbito-zigomatic fractures].

Objective: To evaluate the complications, advantages and disadvantages of the subtarsal approach when used to exposure the orbital rim and orbital floor in orbitozygomatic fractures.

Methods: Retrospective study of the 41 subtarsal incisions that were used in 39 patients with fractures of the zygomatic complex and/or orbital floor, of blowout type, between January 2002 and December 2006.

Results: The observed complications were conjunctivitis, epiphora and noticeable scar, in six (14,6%), five (12,2%) and two (4.
