The brows and forehead are important considerations in planning a blepharoplasty. Forehead wrinkles, ptotic brows, and frown lines can be corrected effectively and safely with minimal complications at the time of, and prior to, the blepharoplasty. Various approaches that we use are presented here. The surgical procedure selected should reflect the defect present and the surgeon's preference.

A child born without scalp, or dura to cover the brain (aplasia cutis congenita) was successfully treated by a multidiscipline team. A coexisting rupture omphalocele forced a change in treatment from the currently recommended regimen of mandatory early scalp closure. Homograft skin was used to protect the brain during the time the omphalocele was treated and skin flaps were delayed. Fluoroscein dye was utilized to determine flap viability and predicted ischemia until after a third delaying procedure was performed. The successful outcome suggests that the present philosophy of early surgical closure being essential for survival in infants with large cranial defects can be altered and, in fact, permanent full-thickness flaps may be designed, tested for viability, and delayed while homograft skin protects the infant's brain from infection and thrombosis.
