Objective- To evaluate the biological compatibility of differentiated stem cells embedded in poly-vinyl-alcohol (PVA) scaffolds for repair of distal femoral cartilage defect. Design- Experimental in vivo study. Animals- Twelve adult male New Zealand white rabbits were used which were divided into two groups (I, II) six rabbits each. Procedures- Mesenchymal stem cells were isolated from h...
Introduction: The standard methods for reconstruction of soft tissue defects in legs are gastrocnemius flap for proximal third defects, soleus flap for middle third and free flap in the distal third. However, there are problems with the use of free flap, like increased operative time, damage of major vessels and the need for experienced microsurgeon. In this study we examined the ability of the...
Objective: Piezoelectric surgical instruments are widely used in medicine and dentistry. Devices with new features produced day by offered to surgeons. The aim of this study is evaluate the effects old generation piezosurgery conventional rotary hand tools on bone after osteotomy histopathologically, histochemically histomorphometrically. Material Methods: In parietal bones 12 rabbits, defects ...
Nowadays, different materials have been used for regeneration of interosseous defects and Neo-Os is one of them. The objective of this study was to evaluate histologically the influence of Neo-Os® particles on bone regeneration using rabbit caivarias defects with and without protection of Gore-Tex® barrier membrane. A cutaneous- periosteal incision and flap was made on the forehead of 32 rabbit...
Background: Lip carcinoma is a common cancer with a good prognosis and when patients refer early in the course of disease the results of treatment are acceptable. Surgical procedures for reconstruction of lip defects are the use of remaining lip tissue, tissue from the opposite lip, adjacent cheek tissue, distant flaps and microvascular free flaps. The bitemporal (visor) flap is a regional...
Reconstruction of the anterior skull base is one of the greatest challenges for reconstructive surgeons. Sometimes, the defect is so large that a local flap is insufficient for the reconstruction. In this report, we present a case of malignant meningioma of the anterior skull base. The tumor was treated by surgical excision resulting in a large defect from the anterior skull base to the nasal c...
This paper describes a new technique in the repair of the hand defect with digital extensor tendon injury. The anterolateral thigh flap with the thick femoral fascia has been used in the reconstruction of the composite defect of the dorsal hand, especially the defect of tendon. This technique requires short period of treatment and hence causes less damage to the donor site but shows a better re...

OBJECTIVES To validate a critical-size mandibular bone defect model in miniature pigs. MATERIALS AND METHODS Bilateral notch defects were produced in the mandible of dentally mature miniature pigs. The right mandibular defect remained untreated while the left defect received an autograft. Bone healing was evaluated by computed tomography (CT) at 4 and 16 weeks, and by micro-CT and non-decalci...
