The existing therapeutical options for the tracheal and pharyngeal reconstruction by use of implant materials are described. Inspite of a multitude of options and the availability of very different materials none of these methods applied for tracheal reconstruction were successfully introduced into the clinical routine. Essential problems are insufficiencies of anastomoses, stenoses, lack of mu...

Background: Palate is a complex structure separating oro- and nasopharynx. However, reconstruction of the defects of palate is much simpler because of the versatile mucoperiosteal flaps. Here, we present our experience of palatal mucoperiosteal flap used in different situations. Methods: Fifteen patients of palatal as well as buccal mucosa defects were reconstructed using either free or pedicl...

Neurocognitive motor tasks have been shown to have an effective relationship with athletic performance and musculoskeletal injuries. Cognitive changes following anterior cruciate ligament reconstruction surgery may lead to adverse knee biomechanical changes and an increased risk of secondary injury. This study aimed to compare the kinetics of athletes with a history of ACL reconstruction and th...

alloderm® (lifecell corp.; brancburg, nj) is an acellular dermal matrix (adm) that serves as an immunologically inert scaffold in plastic surgery. in breast reconstruction, it is used as a filler for lumpectomy defects and can be used to create the inferolateral portion of the tissue expander pocket or implant pocket in postmastectomy patients. however, there are limited reports of the radiolog...

Reconstruction of bone is often required for large bone defects and also in cases of impaired bone regeneration. Vascularized bone transfer has been widely used for reconstruction, especially for segmental mandibular defects, and for reconstruction of long bones of the upper limb and lower limb after trauma or after significant bone resection for tumour. It has also been used in cases of scapho...

The reconstruction of the atrophic alveolar ridges for implant placement is today a common procedure in dentistry daily practice. The surgical reconstruction provides for the optimization of the supporting bone for the implants and a restoration of the amount of keratinized gingiva for esthetic and functional reasons. In the past, tissue regeneration has been performed with autogenous bone and ...

abstract norton’s (1995) investment hypothesis in l2 learning that l2 learners who cherish and foresee a richer personality for themselves in their l2 context would thrive more diligently and consequently would both enrich their personality and achieve a higher proficiency in their new language was investigated in this study in the community of iranian efl students. the integration and mutual r...

Within the precedent decade, a new field of "tissue engineering" or "tissue regeneration" emerge that offers an innovative and exhilarating substitute for maxillofacial reconstruction. It offers a new option to supplement existing treatment regimens for reconstruction/regeneration of the oral and craniofacial complex, which includes the teeth, periodontium, bones, soft tissues (oral mucosa, con...

Tissue engineering is an emerging discipline that combines the principle of science and engineering. It offers an unlimited source of natural tissue substitutes and by using appropriate cells, biomimetic scaffolds, and advanced bioreactors, it is possible that tissue engineering could be implemented in the repair and regeneration of tissue such as bone, cartilage, tendon, and ligament. Whilst r...

Plant propagation originated  from the mature tissues is the most desirable method in producing clonal plants, however microbial contamination usually is the main concern during regeneration processes. Moreover, commercial production of plants using clonal propagation is considered as high throughput method due to the   removal of seasonal barriers, lower cost of production with higher yield wh...
