Scaphocephaly correction with retrocoronal and prelambdoid craniotomies (Renier's "H" technique).

Sep, 2012

The aim of this paper is to describe the surgical technique, originally devised by Dr. Renier which is currently used to treat children with scaphocephaly under 6 months of age at the Craniofacial Unit of Hopital Necker Enfants Malades (French National Referral Center for Faciocraniosynostosis), focusing on its advantages and limitations.

Intracranial compartment volume changes in sagittal craniosynostosis patients: influence of comprehensive cranioplasty.

Jul, 2010

A retrospective analysis of intracranial compartment volume changes in children with sagittal craniosynostosis was performed to clarify the therapeutic objectives of corrective surgery. Ler mais

Outcome analysis of combined lipoabdominoplasty versus conventional abdominoplasty.

May, 2008

Abdominoplasty and liposuction have traditionally been separate procedures. The authors performed a retrospective cohort study to evaluate the outcomes of a novel single-stage approach combining extensive lipoplasty with a modified transverse abdominoplasty. Ler mais

The influence of forehead, brow, and periorbital aesthetics on perceived expression in the youthful face.

May, 2008

The purpose of this study was to characterize the relative influence of eyebrow position and shape, lid position, and facial rhytides on perceived facial expression as related to blepharoplasty, with a specific focus on the perception of tiredness. Ler mais

The shade procedure: for lower lid deformities.

Apr, 2008

Early procedures designed to address fat herniation deformities in the lower lid relied on resection of herniated orbital fat. In some cases, this approach results in an abnormal depression of the periorbital soft-tissue profile and reduced globe prominence. The shade procedure was developed to address these concerns.

Intracranial volume and cephalic index outcomes for total calvarial reconstruction among nonsyndromic sagittal synostosis patients.

Jan, 2008

Controversy abounds as to how craniosynostosis affects intracranial volume and whether more extensive procedures achieve superior results. Intracranial volume and cephalic index were evaluated among nonsyndromic sagittal synostosis patients undergoing cranioplasty. Ler mais

Prostaglandin E2 increases transforming growth factor-beta type III receptor expression through CCAAT enhancer-binding protein delta in osteoblasts.

Nov, 2007

Variations in individual TGF-beta receptors (TbetaRs) may modify TGF-beta activity and significantly alter its effects on connective tissue growth or repair. Differences in the amount of TbetaR type III (TbetaRIII) relative to signal transducing TbetaRI occur on bone cells during differentiation or in response to other growth regulators. Here we investigated prostaglandin (PG) E2, a potent effector during trauma, inflammation, or mechanical load, on TbetaR expression in primary osteoblast-enriched cultures. PGE2 rapidly increased TbetaRIII mRNA and protein expression and enhanced TbetaRIII gene promoter activity through a discrete region within 0.4 kb of the transcription start site. PGE2 alters osteoblast function through multiple signal-inducing pathways. In this regard, protein kinase A (PKA) activators, PGE1 and forskolin, also enhanced gene expression through the TbetaRIII gene promoter, whereas protein kinase C activators, PGF2alpha and phorbol myristate acetate, did not. The stimulatory effect of PGE2 on TbetaRIII promoter activity was suppressed by a dominant negative PKA-regulatory subunit, but not by dominant negative protein kinase C. PGE2 specifically increased nuclear factor CCAAT enhancer-binding protein delta (C/EBPdelta) binding to a half-binding site upstream of the basal TbetaRIII promoter region, and promoter activity was sensitive to C/EBPdelta overexpression and to dominant-negative C/EBPdelta competition. In parallel with their effect on TbetaRIII expression, activators of PKA decreased TGF-beta-induced activity. In summary, high levels of PGE2 that occur with inflammation or trauma may, through PKA-activated C/EBPdelta, preferentially increase TbetaRIII expression and in this way delay TGF-beta-dependent activation of osteoblasts during the early stabilization phase of bone repair.

Strain-dependent control of transforming growth factor-beta function in osteoblasts in an in vitro model: biochemical events associated with distraction osteogenesis.

Jul, 2005

Distraction osteogenesis is an important clinical method for increasing bone mass, but its effects on bone-forming cells are not well understood. In this study, the authors asked how the mechanical forces that occur during this procedure alter specific osteoblast activities such as matrix synthesis, the rate of cell replication, and enzyme activities. The authors further asked whether these changes relate to differences in the biochemical response of osteoblasts to transforming growth factor-beta (TGF-beta), a potent regulator of bone formation.

The bowstring canthal advancement: a new technique to correct the flattened supraorbital rim in unilateral coronal synostosis.

May, 2005

Patients with unilateral coronal synostosis characteristically have a recessed and flattened supraorbital rim ipsilateral to the fused suture. Despite lateral canthal advancement procedures to correct these anomalies, patients often have a persistent flattened and recessed supraorbital rim after surgery. Current procedures address the pathologic features of the orbital rim only partially by advancing forward a deformed supraorbital rim without correcting the abnormal flattening of the normal rim curvature. The authors describe a technique modification of the supraorbital rim advancement procedure that addresses not only the lack of anterior positioning of it, but also its flattened contour: the bowstring canthal advancement.

Complete congenital bony syngnathia in a case of oromandibular limb hypogenesis syndrome.

Jul, 2000

Congenital fusion of the maxilla and mandible (syngnathia) is rare and can present in a wide range of severity from single mucosal bands (synechiae) to complete bony fusion (synostosis). Congenital synostosis of the mandible and maxilla is even less common than synechiae, with only 19 cases reported in the literature. Most of them have presented as an incomplete, unilateral fusion. Only three of the reported cases showed more extensive but still incomplete, intermaxillary bony fusion. We present a case of complete bony fusion of the maxilla and mandible associated with a cleft palate, hypoglossia, micrognathia, unilateral choanal atresia, and limb abnormalities as a feature of oromandibular limb hypogenesis syndrome. Details of operative management are presented. Ler mais
