The purpose of this study was to evaluate the interrelationship of the soft and hard tissue changes after both maxillary and mandibular anterior segmental surgery in bimaxillary protrusion patients. 11 patients had received both maxillary and mandibular anterior segmental surgery and were investigated radiologically with lateral cephalogram. The results were as follows : 1. The correlation of maxillary hard and soft tissue horizontal changes were relative high. : Coefficient between UIE and Stms was 0.89 (p<0.001). 2. The correlation of mandibular hard and soft tissue horizontal changes were very high, especially at the chin. : Coefficients were over 0.90 (p<0.001) 3. All points were moved superiorly except SLS, LS, Stms. 4. Upper and lower lip convexity to the E-Line were decreased (p<0.001) and postsurgical facial profiles were changed very esthetically.

Osteochondroma is a benign tumor that is frequently developed in axial skeleton but rare in TMJ. 61-year old female patient visited local dental clinic with left TMJ crepitus on chewing, trismus and hearing discomforts. She was referred with a tentative diagnosis of TMD. We performed clinical and radiographic examination and could observe large radiopaque lesion at left TMJ. Excisional operation was performed. It was diagnosed finally with a osteochondroma.

This is a case of bony ankylosis of right temporomandibular joint with mild facial asymmetry resulted from trauma, which bring about the right condylar fracture, and corrected by interpositional arthroplasty with temporal fascia flap and coronoidectomy. The postoperative results were functionally and esthetically good, but continued osbervation is necessary to evaluation of abnormal bony growth and reankylosis.

The postoperative maxillary cyst develops as a delayed complication after surgical intervention or Caldwell-Luc operation in the maxillary sinus and was also reported that it could occur after Le Fort I osteotomy. This is also called as surgical cliated cyst because of its lining epithelium is usually lined by a pseudo-stratfied ciliated columnar epithelium. This report represents a case of postoperative maxillary cyst which developed within the anterior of maxilla and in association with nasal mucosa 6 years after a Le Fort I osteotomy. In 1989, 26-year-old male complained of his mandibular prognathism and underwent orthogmathic surgery, Le Fort I osteotomy, bilateral sagittal split ramus osteotomy, partial glossectomy.

When the midfacial fractures involve the upper maxilla (LeFort I, II, III), there is a chance that the nasolacrimal duck may have been injured. When this suspected, We must observe the presence of epiphora carefully. If the epiphora was not improved following conservative treatment, dacryocystorhinostomy would be the treatment of choice. We performed two cases of DCR and got the favorable results.

This is a case report of polyostotic fibrous dysplasia developed in the craniofacial region of 21 year old male patient, who had complained the buccolingual expansion of left mandibular body area, malocclusion and facial asymmetry. We could achieve satisfactory results by radical resection of the relatively well defined small lesion of mandible and by cosmetic bone shaving procedure on the widely dispersed and poorly defined lesions of cranium. But the persistent growth and recurrence of the lesions may produce loss of hearing, visual difficulties, facial paralysis and anosmia, and as it is a polyostotic type occured in the craniofacial region of male patient, the possibility of malignant degeneration should not be excluded completely and periodic recall and check up will be necessary.

Today, with the development of modern civilization, the change of industrial structure and the increase of traffic volume and population make the number of maxillofacial injury patients also increase. Especially, the fracture possibilities of mandibular condyle have been increased because of mandibular position and shape. I experienced the case that mandibular condyle fracture caused by gun-shot injury(Bullet had been packed at the opposite condyle of input site) was treated by foreign body removal and condyle open reduction. I will represent that case with the journal review.

A progressive hemifacial atrophy is characterized by progressive atrophy of subcutaneous fat and rarely muscle and bone. Its contour follows the underlying muscle. Unilateral involvement is common. The treatment goal has been focused on the augmentation of the soft tissue. Many materials such as implants, collagen, fat graft, fat injection, dermal fat graft, filler and vascualized autogenous graft have been used. Although these materials have been used, the best treatment hasn't been achived. In severe cases underlying soft tissue, muscle and bone may be atrophied and massive soft tissue graft, implant and orthognathic surgery must be used. The author used the dermal-fat tissue for the pupose of soft tissue augmentation. We can get the massive soft tissue by the dermolipectomy procedure through the mini-abdominoplsty. The facial augmentation was done by augmentation of the dermal-fat tissue. The progressive hemifacial atrophy is hard to treat by only one procedure and many modalites must be considered.

The acrofacial dysostosis(AFD) is a rare heterogenous disorders combining varying severities of mandibulofacial dysostosis(MFD) with pre and/or post axial limb abnormalities. The Nager syndrome is characterized by preaxial limb defects whereas Miller syndrome is characterized by post axial limb defects. Our AFD case is a 14-year old female. She showed malar hypoplasia, cleft lip & palate(Rt, Lt side), wide nasal bridge, telecanthus. Her right thumb was abscent and middle phalanx, radius, carpal bones of right hand were hypoplastic, and metatarsus varus was present. She showed normal stature and intelligence.

Malocclusion can be often found after improper reduction of facial bone fractures, especially by the plastic surgeon or other medical doctor. This causes lots of problem in esthetics, mastication, or facial symmetry. We present four cases which are related above problems. These were well treated by orthognathic surgery or orthodontic treatment.
