BACKGROUND After radical ablation of tumors, colon or jejunum is pulled up for reconstruction of the thoracic esophagus when stomach is unusable. However, esophagocolonic or esophagojejunal anastomotic leak is relatively frequent because of the potential for vascular insufficiency of conduit extended upward. METHODS To overcome this disadvantage, 14(More)
Distraction osteogenesis has become a standard technique for craniomaxillofacial reconstruction. The authors performed gradual cranial vault distraction osteogenesis in 19 patients with craniosynostosis to study the outcome and complications of this procedure. Postoperative infections developed around the shaft puncture wounds in four patients, including(More)
In fibrous dysplasia (FD), growth of the lesions usually arrests around early adolescence. However, in some cases, it continues even after this period, and it is not clear under what kind of conditions this growth continues. If this continued growth could be predicted, it would provide a vital assessment tool to determine when bone contouring should be(More)
Various complications of Le Fort osteotomies have been reported. We describe a lethal complication of Le Fort III osteotomy we encountered in a 9-year-old boy with Crouzon syndrome. A standard Le Fort III osteotomy, including pterygomaxillary dysjunction with a curved osteotome and down-fracture manipulation, was performed uneventfully. When the intraoral(More)
There have been recent reports of acute compartment syndrome secondary to suction injuries of the hands of children. We report the case of a 68-year-old patient who developed an acute compartment syndrome of the forearm after his arm had been sucked into an exhaust port. He was treated by emergency fasciotomies and the wound was closed five days later with(More)
Conventional methods of Z-plasty, a basic technique of plastic surgery, are incorrect since they are based on the assumption that the suture lines as designed prior to Z-plasty and those that actually result will coincide. For Z-plasty to be satisfactorily applied in scar revision, sufficient thought must be given to the actual directions in which the(More)
Autogenous calvarial bone grafts have been widely used in craniofacial reconstruction following trauma, congenital anomalies, and head and neck tumors. In cases of late restoration of a collapsed cranial vault, an extradural dead space is occasionally observed which might cause infection and grafted bone absorption. The combined use of a split calvarial(More)
Many techniques for reconstruction of an absent umbilicus have been described; however, none has achieved a perfect result. We report a new alternative for constructing an umbilicus using a conical flap and present two representative clinical cases. Our technique creates an umbilicus with sufficient depth with good results, including maintenance of depth(More)
A model of infected skin ulceration could prove useful in assessing the clinical effectiveness of antimicrobial ointments and dressings. However, no such models have been previously established. Three types of wound were induced in rats: full-thickness wounds covered with gauze, burn wounds and wounds resulting from mechanical trauma. Wounds were inoculated(More)
Recurrent subareolar abscess is an infrequent but troublesome disease of the breast among young women. Recent experience with 5 patients indicated that successful treatment of recurrent subareolar abscess requires excision of the diseased ducts and necrotic cavity, including the inverted section of the nipple. The operative procedure described herein allows(More)
