OBJECTIVE To explore nasolabial movements in participants with repaired cleft lip and palate. DESIGN A parallel, three-group, nonrandomized clinical trial. SUBJECTS Group 1=31 participants with a cleft lip slated for revision surgery (revision), group 2=32 participants with a cleft lip who did not have surgery (nonrevision), and group 3=37 noncleft(More)
Voltage has historically guided the acute management and long-term prognosis of physical morbidity in electrical injury patients; however, few large studies exist that include neuropsychiatric morbidity in final outcome analysis. This review compares high (>1000 V) to low (<1000 V) voltage injuries, focusing on return to work and neuropsychiatric sequelae(More)
Biodegradable plates and screws are recommended for use in surgery of the craniofacial skeleton of children. To be effective and not interfere with growth of the child's skull, the plates must biodegrade sufficiently to release the holding power of the plate and screw within 1 year. It is also essential that excessive foreign body reaction and cyst(More)
BACKGROUND The purpose of this article was to review the senior author's 20 years of experience in the treatment of pediatric breast abnormalities, to propose a classification system for their treatment, and to provide a synopsis of treatment options. METHODS Congenital and acquired breast anomalies were identified in a retrospective chart review (n =(More)
OBJECTIVE Children with a cleft of the upper lip exhibit obvious facial disfigurement. Many require multiple lip surgeries for an optimal esthetic result. However, because the decision for lip revision is based on subjective clinical criteria, clinicians may disagree on whether these surgeries should be performed. To establish more reliable, functionally(More)
This report discusses the incidence of twinning in nonsyndromic and syndromic craniosynostosis. Nonsyndromic craniosynostosis occurs in approximately 1 in 2,100 live births; the incidence of twinning in patients with nonsyndromic craniosynostosis has been reported to be higher than the rate of 2.5% of live births in the general population. No definitive(More)
Bilateral coronoid hyperplasia is a relatively rare condition in the pediatric population and yet may be an unrecognized cause of limited mouth opening in children. There are multiple theories as to the causes of the hyperplasia, which include temporalis hyperactivity, hormonal stimulus, and genetic inheritance. The resulting excess growth of the coronoids(More)
Our previous work demonstrated that geriatric trauma patients (age greater than 65 years) consume disproportionate amounts of health care resources. In the past we hypothesized that late mortality is high, long-term outcome is poor, and return to independence is low in a severely injured geriatric population. Of 6,480 trauma admissions over 5 years,(More)
The seminal work of Mulliken and Glowacki in 1982 elucidated the histological differences between hemangiomas and vascular malformations: the former are characterized by endothelial cell proliferation, whereas the latter contain mature endothelial cells. Hemangiomas proliferate and then involute, whereas malformations remain stable in size, growing(More)
Tissue engineering has largely focused on single tissue-type reconstruction (such as bone); however, the basic unit of healing in any clinically relevant scenario is a compound tissue type (such as bone, periosteum, and skin). Nanofibers are submicron fibrils that mimic the extracellular matrix, promoting cellular adhesion, proliferation, and migration.(More)
