Background: Periosteum-mediated bone regeneration (PMBR) is a known mandibular reconstruction. Though poorly understood and unpredictable, the concerns of developmental changes to donor recipient tissues shared by other treatment options appear nonexistent. The definitive role periosteum during in any mammal remains understood.
 Objective: To characterise genetic determinants PMBR mammals ...

OBJECTIVE To use the periosteum as a barrier in treatment of buccal Grade II furcation defects of lower molars. MATERIALS AND METHODS This technique was performed on 12 patients with bilateral buccal Grade II furcation defects of lower molars. On a random basis, one furcation defect of each pair was selected for the control group and other for the experimental group. Debridement was done in t...

Human jaw periosteum tissue contains osteoprogenitors that have potential for tissue engineering applications in oral and maxillofacial surgeries. To isolate osteoprogenitor cells from heterogeneous cell populations, we used the specific mesenchymal stem cell antigen-1 (MSCA-1) antibody and compared two magnetic separation methods. We analyzed the obtained MSCA-1(+) and MSCA-1(-) fractions in t...

Introduction: In contrast to endochondral growth with ossification of a pre-existing cartilaginous matrix, cranial sutures act as intramembranous bone growth sites. New bone is produced at the sutural edges by proliferation of mesenchymal cells and subsequent differentiation into osteoblasts. The suture itself remains in an unossified stage in which maintenance of growth at the osteogenic front...

Permanent facial paralysis is a catastrophic event for involved patients. In long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. But its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. This article advocate a new modification for resolving this problem with concomitant el...

Under infiltration anaesthesia a hockey-stick incision, about 4 in. long, is made I-5 cm. in front of the tragus (Fig. i). A skin flap is reflected forwards and downwards and the fascia covering the temporalis muscle is exposed. Two parallel and nearly vertical incisions, 2 in. long and 8 mm. apart, are made in the temporalis fascia; these are joined at the base by a horizontal incision. The ve...

An autoradiographic study has been made of mouse femora from birth to one year of age. Tritiated thymidine was used to study the proliferative rate of various skeletal tissues. The labeling index of the periosteum was found to be highest at birth (0.085). At 8 weeks of age the index fell sharply to 0.007 and remained low throughout the entire period of study. Chondro-osteogenic cells of the per...

At present there is no satisfactory treatment for deep osteochondral defects. Here we report the development of a biologic prosthetic composite containing periosteum from 2-month-old rabbits and a porous tantalum scaffold. When cultured under chondrogenic conditions, the composites form a robust hyaline-like cartilage outgrowth that is attached to the porous scaffold by fibrous tissue ingrowth....

We analyzed the incidence and interaction of arteriolar vasomotion and capillary flow motion during critical perfusion conditions in neighboring peripheral tissues using intravital fluorescence microscopy. The gracilis and semitendinosus muscles and adjacent periosteum, subcutis, and skin of the left hindlimb of Sprague-Dawley rats were isolated at the femoral vessels. Critical perfusion condit...

AIMS Surgical treatment of nasal septal perforation remains a challenging field of rhinology. A large variety of techniques and grafts with promising results have been introduced for perforation repair. However, the use of fascia or fascia with periosteum has not been previously evaluated for a large sample of patients. METHODS During the years 2007-2014, 105 operations were performed and 98 ...
