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

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.

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

Methods: Chart and computed tomographic review of 53 consecutive children with previously unoperated sagittal synostosis was performed, and preoperative and postoperative computed tomographic scans were examined and compared with 143 age- and gender-matched controls.

Results: Preoperative mean intracranial compartment volume and mean brain tissue volume of each subgroup were age dependent.

Outcome analysis of combined lipoabdominoplasty versus conventional abdominoplasty.

Background: 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.

Methods: One hundred fourteen patients were evaluated for abdominal contouring.

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

Background: 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.

Methods: A standardized photograph of a youthful upper face was modified using digital imaging software to independently alter a number of variables: brow position/shape, upper/lower lid position, pretarsal show, and rhytides. Subjects (n = 20) were presented with 16 images and asked to quantify, on a scale from 0 to 5, the presence of each of seven expressions/emotions as follows: "surprise," "anger," "sadness," "disgust," "fear," "happiness," and "tiredness.

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

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.

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

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.
