Island fasciocutaneous flap based on the proximal perforators of the radial artery for resurfacing of burned cubital fossa.
In the vast majority of burned patients, the injury is limited to the skin and superficial subcutaneous tissue, and the vasculature of the deeper fascia is spared. This fact encouraged me to design a flap in which the burned scar tissue is employed. ⋯ The flap is used to resurface the anterior as well as the lateral burned cubital fossa after excision of the scar tissue and release of contracture. An anatomic study as well as clinical approach has been conducted.

The medical profession is besieged by concerns about cost containment. This in turn has focused attention on the use of ambulatory surgical facilities. However, the costs of hospital outpatient surgery programs usually prevent them from being competitive when compared with the costs of using office surgical facilities. ⋯ A death occurred in 1 in 57,000 cases (0.0017 percent). The overall risk is comparable in an accredited office (plastic surgical facility) and in a free-standing or hospital ambulatory surgical facility. This study documents an excellent safety record for plastic surgery done in accredited office surgical facilities by board-certified plastic surgeons.

Reduction of progressive burn injury by using a new nonselective endothelin-A and endothelin-B receptor antagonist, TAK-044: an experimental study in rats.
Endothelins are well-known vasoconstrictor peptides produced by vascular endothelial cells that have been reported to have a fundamental role in regulation of the systemic blood circulation. Plasma levels of endothelins are increased by burn injury, which also causes thrombosis and occlusion of vessels in the dermis as well as a vascular response in the adjacent uninjured dermis. Diminished blood flow leads to progressive ischemia and necrosis of the dermis beneath and around the burn (zone of stasis). ⋯ This supports the role of endothelins in the progression of burn injury in the zone of stasis. TAK-044 was most effective in preventing progressive burn damage at a dose of 1 mg/kg. The extent of necrosis and edema was reduced significantly, and blood flow in the zone of stasis was increased in the treated rats.

Comparative StudyThe lateral nasal osteotomy in rhinoplasty: an anatomic endoscopic comparison of the external versus the internal approach.
A precise and reproducible lateral osteotomy is a requirement for successful rhinoplasty. Two basic techniques have evolved: the external perforated method and the internal continuous method. The literature supporting the external perforated technique maintains that it contributes to a controlled, stable fracture and produces less nasal airway narrowing, hemorrhage, edema, and ecchymosis; however, the continuous internal method is used by many rhinoplasty surgeons. ⋯ In a blinded fashion, four different investigators used nasal endoscopy to detect mucosal perforations and bony irregularities. Eleven percent of the perforated osteotomies resulted in mucosal tearing as opposed to 74 percent of the continuous osteotomies (p < 0.001). This anatomic study confirms our clinical experience that the external perforated osteotomy results in a more controlled fracture with less intranasal trauma and can minimize the associated morbidity (hemorrhage, edema, and ecchymosis) in the rhinoplasty patient.
