Rhinoplasty is a complex operation that requires precise preoperative diagnosis to select the appropriate surgical technique. In reduction rhinoplasty, I generally use the external rhinoplasty approach. Most dorsal humps are comprised primarily of cartilage, and overreduction of the bony dorsum must be avoided. The decision concerning the extent of hump removal should be determined preoperatively. Following hump removal and to close the open roof, osteotomies are considered for repositioning and reshaping the nose. A medial osteotomy is defined as the separation of the nasal bones and the bony septum. This can be further subclassified as medial oblique and paramedian osteotomies. I prefer to use a fading medial osteotomy(medial oblique). The fading medial osteotomy avoids those deformities created by extending osteotomies into the thick frontal bone. A lateral osteotomy may be used to narrow a wide nasal base, or to close open roof deformity. "Low-high", "low-low" and double osteotomies have been described. After dorsal hump removal and osteotomies, I frequently use spreader grafts to reconstruct middle nasal vault.

This study includes 19 cases of complicated low extremity injury to whom underwent microvascular free-tissue transfer in cases of open comminuted fracture, osteomyelitis, and vascular compromise or extensive soft tissue defect from Nov. 1994 to July 1997. The average time after injury to coverage was 25 days. The nineteen patients underwent a total of nineteen free tissue transfers primarily, and eighteen (94.7 per cent) of the transfers survived. Major complications were encountered recurrent failure of the free tissue transfer in one patient and partial necrosis in the other flap, which were successfully treated by flow-through radial forearm free flap and distally based superficial sural artery flap respectively. Two patients were sustained below knee amputation, one above knee amputation, despite of survival of flaps. This reveals limb salvage in 84 percent. The microvascular reconstruction is a versatile and reliable methods in complicated cases after severe trauma. Free tissue transplantation should be considered as a primary treatment in such complicated cases.

Congenital intraspinal epidermoid tumors, while rare, do occur ; that they are related to spinal puncture is less well understood. This article describes the case of a 10 year-old boy with intraspinal epidermoid tumor, who five years previously had undergone lumbar puncture. A striking clinical features of this case is pain in the lower extremity. In this report, we review the literature and discuss the probable developmental mechanism of such tumor.

Aneurysmal bone cyst is an uncommon spinal tumor of vascular origin and represents less than 1% primary bone tumors. A case of 15-year-old girl who presented with low back pain and severe left leg pain. The lesion was expansile in nature involving anterior and posterior bony elements of the spine. It also showed expanision into the intraspinal canal and paraspinal soft tissue. Surgical treatment consisted of tumor excision and pedicle screw fixation via extracavitary approach. Postoperative course was uneventful and her symptoms and signs were improved. Extracavitary approach, as applied to our case, seemed to be an ideal surgical method in such cases because of its nature and extent of involvement.
