Mandibular prognathism was defined by Johe Hunter as follows : 'The lower jaw projecting too far forwards so that the foreteeth pass before those of upper jaw, therefore disfigurement and malocclusion are the two of facial main characteristics.' Mandibular ramus osteotomy by vertical osteotomy or sagittal splitting osteotomy recently has come into more common use. Although preoperative and postoperative orthdontic management is indispensable in surgery of this type, we occasionally encounter patients who are intolerant to a long duration of orthodontic treatment and intermaxillary fixation. We describe surgical refinement accomplishing mandibular anterior segmental osteotomy, recession genioplasty by horizontal osteotomies and decortication of the anterior portion of the bony bar for a minor degree of mandibular prognathism. In results, the amount of setback is limited to 4 to 5mm, no intermaxillary fixation is required and no orthodontic treatment, in this operation, is needed. This procedure can obtain a rapid aesthetic improvement. We used this preocedure in 8 patients (3 males and 5 females) with a mild mandibular prognathism. No major complications occurred throughout the follow-up period except transient paresthesia of the mental nerves, otherwise all patients were satisfied with the result.

This paper contains the results of clinical and neuroradiologic studies in 9 cases of histopathologicallyverified intracranial cavernous hemangiomas. The most common clinical presentations were focal seizure andheadache which were accompained by focal neurologic deficits. Skull films revealed abnormality in 3 cases andcerbral angiography revealed an avascular area in 8 cases, but both were of little diagnostic significance. CTusually demonstrated a hyperdense, cystic and calcified lesion without significant mass effect, and mild degereeof tubular or ring like enhancement after contrast injection. The follow-up CT findings in 4 cases over a 6-monthperiod were compatible to repeated minute hemorrhage and resolution. The above clinical and CT findings and , ifpossible, repeated CT could suggest the diagnosis of cavernous hemangioma and provide the proper management,including the avoidance of unnecessory radiation therapy and biopsy related complications.

Many Oriental women have prominent mandibular angle and short chin, in other words, 'squared' mandibular face or 'boxy' face. That kind of face is considered to be unattractive and causes big cosmetic problems for those who want to have an ovoid or almond shaped face. A squared mandibular face often needs to be corrected by operative procedure. A reduction mandibular angleplasty by bony angle resection is one of the operative procedures, but it is not always an adequate method. The successful correction of squared mandibular face can be accomplished by horizontal facial reduction and/or vertical facial lengthening procedure. From March 1996 to March 2000, We had operated 117 patients. The patients were divided into 3 groups. Group I had prominent mandibular angle and/or massetric hypertrophy. Patients in this group were operated by reduction angleplasty with/without resection of masseter muscle. Group II had prominent mandibular angle, cheek and mandibular body. In this case, we applied reduction angleplasty, contouring of body, resection of buccal fat pad and/or masseter muscle. Group III had prominent mandibular angle with short face. We used methods used for group II and Le Fort I lengthening and genioplasty. Ancillary procedures were forehead lengthening and reduction maloplasty. Successful correction of squared mandibular face could be performed by accurate analysis of facial profile and reduction mandibular angleplasty with proper ancillary procedures for each group. The results were as follows: 1) We obtained successful correction of squared mandibular face with multiple horizontal facial reduction procedures, which reduced anterior and posterior facial plane. 2) In case of short face, we made better mid-low facial balance with vertical facial lengthening and horizontal facial reduction.

We report a case of primary osteosarcoma of the breast which is rare and exhibits poor prognosis. A 52 years-old-woman was admitted with rapidly growing right mammary mass. A huge lobulated dense mass with speckled calcifications, suggesting malignancy, was observed on mammography. She underwent a radical mastectomy. Grossly, the mass measured 16 14 6 cm and showed grayish white hard lobulated tissue with focal hemorrhage and necrosis. Light microscopically, the tumor was confirmed as an osteosarcoma devoid of any epithelial components. In postoperative whole body bone scan, there was no evidence of the other malignancy. To the best of our knowledge, the present case is the first report of primary osteosarcoma of the breast in Korea.

The characteristics of modern society's trauma is a propensity for multiple and severe trauma, specially, the fatal damage accompanied by facial bone fracture. We observed the malocclusion owing to delayed prompt treatment If the fractured fragments is crushed severely, it is difficult to make them positioned into the normal anatomical states and to fix them tightly. Post-traumatic malocclusion is usually caused by a delay in treatment and inadequate anatomic reduction. Inadequately treated facial bone fractures result in facial disfiguring and functional impairment of mastication and speech.We performed 27 cases of correction of post-traumatic malocclusion between April 1994 and June 1996. We used various operative techniques such as anterior segmental osteotomy, Le Fort osteotomy, maxillary segmental osteotomy and mandibular sagittal split osteotomy. If the malocclusion was due to disarrangement segmental osteotomy. If that malocclusion was attributed to a malpositioned skeletal bone, we take maxillary segmental osteotomy or mandibular sagittal split osteotomy. We acquired the desirable occlusion first followed by a fixation between the mandible and maxillary skeletal bones with the bite block. The aim in the correction of malocclusion was to create a harmony of centric relation and centric occlusion. After operation, intermaxillary fixation with bite block have many advantages in the treatment of malocclusion.

A multitude of methods for correction of the residual cleft lip nose deformity have been developed. Inspite of the development it appears that no one procedure has achieved satisfactory results. In addition, the appropriate timing for surgical correction still remains unsettled. The philtrum plays a keyhole in the appearance of the upper lip and nostril sill. But the formation of philtrum with muscle flap or conchal cartilage have been resulted in a unsatisfactory aesthetic outcome. We performed 26 cases of the correction of unilateral cleft lip nose deformity between May 1993 and September 1996, and we always used autogenous palmaris longus tendon for reconstruction of philtral column and nostril sill augmentation. Palmaris longus tendon creates a more definite philtral unit comparing to other materials which have been used and it is easy to harvest and transfer and it does not affect normal function of the hand. And we followed up all patients and confirmed that disappearance of newly formed philtrum is rare. In conclusion, this study shows that autogenous palmaris longus tendon is a useful material for reconstruction of philtral column.
