Masseter Muscle Reattachment After Mandibular Angle Surgery
BACKGROUND: Altering the dimensions of the mandibular angle by alloplastic augmentation or skeletal reduction requires elevation of the insertion of the masseter muscle, including the pterygomasseteric sling. Disruption of the pterygomasseteric sling during exposure of the inferior border of the mandible can cause the masseter muscle to retract superiorly, resulting in a loss of soft […]
MoreTissue Engineering Cartilage with Aged Articular Chondrocytes In Vivo
Background: Tissue engineering has the potential to repair cartilage structures in middle-aged and elderly patients using their own “aged†cartilage tissue as a source of reparative chondrocytes. However, most studies on tissue-engineered cartilage have used chondrocytes from postfetal or very young donors. The authors hypothesized that articular chondrocytes isolated from old animals could produce neocartilage […]
MoreClinical Application of Cultured Autologous Human Auricular Chondrocytes with Autologous Serum for Craniofacial or Nasal Augmentation and Repair
The authors have corrected various craniofacial contour deformities using tissue culture- expanded autogenous tissue. Their method involves obtaining small cartilage biopsy specimens, expanding the number of cells from the biopsy specimens in tissue culture, and injecting the expanded cells into the defect. The authors’ initial clinical results using this procedure are impressive. In addition to […]
MoreInfracture Technique for Reduction Malarplasty with a Short Preauricular Incision
Certain horizontal facial measurements in Asians are significantly greater than those of Westerners. These measurements include the bizygomatic distance, the intercanthal distance, the interalar distance, and the bigonial distance1 (Fig. 1). Aesthetic operations designed to improve balance or proportion in Asian faces typically, directly or indirectly, reduce these horizontal measurements. Dorsal nasal augmentation makes the […]
MoreSecondary Reconstruction of Posttraumatic Orbital Deformities
A retrospective analysis of our experience, techniques, and concepts for the secondary reconstruction of orbital injuries to 78 patients over a 15-year period is presented. Secondary orbital reconstruction has the following four basic steps: II) freeing of the overlying soft tissues by extensive subperiosteal dissection; (2) skeletal reconstruction, usually with onlay bone grafting and contour […]
MoreInfraorbital Rim Augmentation
In patients with recessive infraorbital rims, alloplastic augmentation of the infraorbital rims makes the eyes appear less prominent and improves appearance. Ten patients (seven women and three men) with an average age of 30 years (range, 23 to 45 years) underwent augmentation of the infraorbital rim with alloplastic implants over a 9-year period. With an […]
MoreMandibular Augmentation
Porous polyethylene implants are available that are designed to augment the mandibular ramus and body. They can be used to increase the bigonial distance in patients with normal mandibular anatomy who desire an increase in lower facial width. When used in combination with extended chin implants, they can camouflage the skeletal contour inadequacies associated with […]
MoreImproving Periorbital Appearance in the “Morphologically Proneâ€
Patients with prominent eyes are predisposed to lower lid descent and rounding of the palpebral fissure. This deformity may be exaggerated and symptomatic after conventional lower blepharoplasty. Normalization of the periorbital appearance in “morphologically prone†patients involves three basic maneuvers. Augmenting the projection of the infraorbital rim with an alloplastic implant effectively changes the skeletal […]
MoreMaking Concave Faces Convex
Abstract. Inadequate projection of the midface skeleton results in midface concavity. Patients with this skeletal morphology tend to have prominent eyes and noses. Lack of skeletal support for the midface soft tissue envelope predisposes to premature cheek descent, resulting in palpebral fissure distortion and lower lid “bags,†an appearance of early aging. Concave midfaces can […]
MoreParanasal Implants for Correction of Midface Concavity
Central midface concavity was corrected with the placement of porous polyethylene implants in the paranasal area. This simulated the effect of skeletal osteotomies and advancement without altering dental occlusion. Implants were placed to correct congenital, posttraumatic, and cleft related skeletal midface retrusion in nine patients. In seven of the patients, paranasal augmentation was performed in […]
