BACKGROUND The parapapillary gamma zone has recently been defined as the parapapillary region free of Bruch's membrane. Although it has been reported the presence of defects in peripapillary gamma zone, hitherto undescribed is the herniation of the retinal nerve fiver layer tissue into the peripapillary gamma zone defect with the resulting localized defects in the retinal nerve fiber layer. C...
BACKGROUND The optimal design of a skin flap requires an understanding of the concepts of tissue movement. OBJECTIVE The purpose of this manuscript was to demonstrate concepts of sliding and lifting tissue movement for flap reconstruction. METHODS Six similar defects located in the forehead-temple-eyebrow region were repaired using a different skin flap. RESULTS The specific flap design f...
Large area eyelid defects induced by human biting was rare. A 43-year-old man was bited by a human. His Blepharocoloboma size was 60% percent of the upper eyelid, the horizontal defect length of defect area was 25mm, the vertical height was 5mm,a small mass like lateral eyelid tissue was left on the Lateralis lid margin. The toughness of this lateral eyelid tissue was enough to support the late...

Method: This research was a cross sectional- descriptive study. Community included of all student with autism in Tehran and sample included 50 children with autism that selected by purposive samplin...
The aim of this study was to evaluate the osteocalcin immunoexpression during the bone repair treated with subcutaneous adipose tissue in rats and rabbits. Fourteen rats and 14 rabbits were used in the study. A critical-sized calvarial defect was created in each animal. The animals were divided into 4 experimental groups: RC (rat control), RbC (rabbit control), RAT (rat adipose tissue), RbAT (r...
with a small ventricular communication, to a large ventricular septal defect dominating the picture with mild obstruction. When the pulmonary stenosis is mild, whether the ventricular septal defect is small or large, a left-to-right shunt is always present, giving the clinical picture of a ventricular septal defect. On the other hand, if the stenosis is severe and the ventricular septal defect ...
A 32-year-old male came to the emergency room with a crescentric 4x11 cm tissue defect at the right temporo-parietal region. Brain tomography showed a tissue defect in the right parietal region but bone integrity was preserved. A free flap procedure was performed to protect the cranial bones. Two months after discharge from the hospital, he presented with a draining dirty wound that appeared ne...
Reconstruction of large abdominal wall defects is a challenging problem. Various reconstructive techniques have been described in the surgical literature each with its advantages and disadvantages. In this report we describe our experience in treating a patient with large abdominal wall defect by staged abdominal wall reconstruction utilizing prosthetic mesh in conjunction with tissue expanders...
A congenital or iatrogenic tissue defect often requires closure by open surgery or metallic components that can erode tissue. Biodegradable, hydrophobic light-activated adhesives represent an attractive alternative to sutures, but lack a specifically designed minimally invasive delivery tool, which limits their clinical translation. We developed a multifunctional, catheter-based technology with...
