OBJECTIVES Reconstruction of large mandiblular defects following ablative oncologic surgery could be done by using vascularized bone transfer or, more often, primarily with simultaneous or delayed bone grafting, using load bearing reconstruction plates. Bending of these reconstruction plates is typically directed along the outer contour of the original mandible. Simultaneously or in a second op...

Extensive maxillofacial defects resulting from trauma or oncologic resection present reconstructive challenges. Various autografts and alloplastic materials in conjunction with standard soft-tissue techniques have been used in the reconstruction of these types of defects. Polyetheretherketone (PEEK) is a semicrystalline polyaromatic linear polymer exhibiting an excellent combination of strength...

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 year...

Frontobasal injuries and some other diseases of frontal sinuses sometimes require radical surgery with the obliteration of the sinus. A cosmetic correction of the forehead and supraorbital arches has to be performed after such a procedure. Nowadays, there is a wide choice of alloplastic materials on the market. We tried polymethyl methacrylate implants in correction of the exterior appearance o...

Introduction: The temporomandibular joint (TMJ) is composed of dense fibrocartilage formed between the mandibular condyle and temporal bone. high collagen content this disc provides great rigidity durability. Osteoarthritis-like degenerative disease belonging to disorder (TMD) a destruction bone cartilage with consequent inflammation that enhances tissue destruction. As treatment, implantation ...

INTRODUCTION Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. PURPOSE To report 15 cases treated by either gap arthroplasty, or the articular reconstruction technique using costochondral grafts, coronoid process grafts or al...

The aim of this study was to assess the nostril symmetry following primary cleft rhinoplasty done with either a dorsal onlay or columellar strut graft in patients with non-syndromic complete unilateral cleft lip and palate. In this retrospective study 30 consecutive patients treated with autogenous or alloplastic dorsal onlay grafts and 30 consecutive patients treated with autogenous or allopla...

Complex augmentation rhinoplasty to correct both functional and cosmetic deformities remains a challenge for the rhinoplasty surgeon. The skeletal structure maybe severely deformed from previous trauma or underlying disease processes. These resulting deformities may occur together with significant soft tissue disfigurement. Correction of all these aspects requires careful selection of graft mat...
