Background: Reduction malarplasty is one of the most popular facial contouring surgeries in east Asia for making patients' faces smaller. Currently in Korea, reduction malarplasty surgeries are performed mostly at plastic surgery clinics, but few cases are done at oral and maxillofacial surgery clinics. The reason might be because of post-operative complications after reduction malarplasty, such as undercorrection, overcorrection, asymmetry, cheek drooping, malunion, pain and noise. Those complications should be uneasy to be handled by oral and maxillofacial surgeons, however, they can be prevented by knowing the effective and safe reduction malarplasty techniques. Therefore, in this article the author as an oral and maxillofacial surgeon, would like to suggest safe and effective surgical methods for reduction malarplasty customized for Korean patients. Method: L- shape osteotomy of zygomatic body was performed with intraoral approach via vestibular incision, and the zygomatic arch was osteotomized with extraoral approach via sideburn incision. Then zygomatic complex was separated and rotated mesio-superiorly without removal of a bony strip and fixed with miniplates and microplates without making a bony gap. Conclusion: Surgical results were favorable and satisfied by the patients without cheek drooping, malunion, undercorrection and asymmetry.

Objective : The aim of this study is to report the effect of Hani-maehwa laser(fractional mode) treatment on acne scar. Methods : The patient with atrophic facial acne scars was treated with 5 sessions of laser therapy at 4-week intervals. The therapeutic response to treatment was assessed at 3 months after last laser session. The treatment effect was evaluated by standardized photography, anti aging, skin brightness and flatness. That was measured by micro fluorescence measurement camera(ECO SKIN, Cuvitz Inc.) in 16(left zygoma) and 26(right zygoma) spot. And side effects were also checked. Results : Atrophic facial acne scars have improved markedly. Anti aging, skin brightness and flatness were improved. Especially anti aging and flatness were noticeably improved. Adverse effects were not reported.Conclusions : Korean medicine cautery method applies to high level laser(CO2 Hani-maehwa laser). These are different designs but same principle. It can be considered that laser therapy is effective method for treating acne scars.
The author has arrived at the following result after having carried out multilateral study based on a total of 282 maxillofacial fracture patients who have receive treatment at the Euijeongbu general hospital and Shinchun general hospital in the northern district of Kyunggido from march 1988 to august 1990. 1.

Fibrous dysplasia is an idiopathic skeletal disorder in which medullary bone is replaced and disturbed by poorly organized, structually unsound fibroosseous tissue, which may produce cortical expansion. When facial bones are involed, considerable esthetic deformity may result. The term monostotic fibrous dysplasia has been applied when one bone is involved : when more than one bone is affected, the term polyostotic used. The polyostotic form may be accomplished by pigmented skin lesion (Jaffe type), or by pigmented skin lesions with endocrine disturbance (Albright syndrome). No general agreement exists on the cause of fibrous dysplasia. A few authors have suggested that fibrous dysplasia arises as a resujlt of trauma. It occurs predominantly in infant, adolescent females and runs a variable clinical course. When several bones are involed, it tends to be unilateral. Involements of alveolar bone may produce displacement of teeth with malocclusion, or loss of teeth, or both. Radiographycally, it shows an indistinctly delimited osteolytic defect with a bubble - like pattern, but without a sclerotic rim. The preferred treatment is almost always surgery. If the lesion is extensive, surgical intervention with use of recontouring procedures aimed at the correction of esthetic or funtional disturbances is preferred treatment. Now, we present a case of fibrous dysplasia on the left maxilla and the zygoma treated by bony contourign via hemicoronal flap and intraoral approach with good results.

Purpose: The zygomatic arch is a key element which composes the facial contour. In many cases of zygomatic arch fracture, it is difficult to fix rigidly the fractured segments. If reduced bone segments were not fixed rigidly, they are proven to be displaced by mastication or unintentional external forces. So, unfixed zygomatic arch fracture after reduction may require a external device of prevention of collapse. We introduce a new protector which stabilizing the fractured segments to prevent for collapse of the reduced zygomatic arch fracture. Methods: After reduction of zygomatic arch with blind approach(Gillies', Dingman or Keen's approach), bone segments was pulled with percutaneous traction suture in medial aspect of zygomatic arch. Then, the suture was fixed with Aqua $splint^{(R)}$, externally. And intraoperative and postoperative X-ray was done. The splint was removed on 14 days after the operation. Results: 5 patients were treated with this method. 4 patients of total patients had no collapse in zygomatic arch. There was minimal collapse in one patient. Postoperative complications such as facial nerve injury, mouth opening difficulty, contour deformity, infection, scar were not observed. Conclusion: In comparison with other techniques, this technique has several advantages which are simple and easy method, short operation time, no scar, less soft tissue injury, and facilitated removal of splint. Therefore, Aqua $splint^{(R)}$ would be a good alternative to prevent for collapse in unstable zygomatic arch fractures

Purpose: Brown's syndrome is characterized by the limited elevation in adduction from mechanical causes around the superior oblique tendon trochlea complex. In this particular case, post-traumatic facial deformity accompanied by Brown's syndrome was observed. We would like to report the satisfying cosmetic results obtained by reconstructing orbital roof and superior orbital rim and repositioning of zygoma. Methods: A 12-year-old patient was observed with facial deformity with strabismus in her right eye and orbital dystopia after the car accident and was eventually diagnosed with traumatic Brown's syndrome. Reconstructive surgeries could not be performed at the time of trauma due to the cerebral hemorrhage. At the second year after the trauma, a depressed fracture of the right orbital roof and superior orbital rim were reconstructed via the intracranial approach, and orbital dystopia was corrected via the zygoma triple ostectomy. In addition, a strabismus surgery was performed one year after her plastic surgery. Results: Facial deformity with orbital dystopia and strabismus was confirmed to be fully reconstructed after the surgery. Moreover, when the patient came in for a follow-up thirteen years after the operation, a developmental imbalance of the facial bones, diplopia, or any other surgical complications were not to be found. Conclusion: After the trauma, the patient with Brown's Syndrome accompanied by post-traumatic facial deformity, who went under the corrective surgeries after the meticulous examination and assessment pre-surgically, was able to acquire cosmetic satisfaction via those operations.

The zygoma is second most commonly vulnerable facial bone in fracture, in number only by nasal fractures. It is difficult to evaluate reduction state intraoperatively, because almost surgeons reduce the fractured zygoma by blind method. We suggest the use of orthopedic C-arm intraoperatively. We use plain radiography, CT to evaluate preoperative state. Gilles approach or intraoral approach were used to reduce the fractured zygomatic arch. The C-arm was positioned at chin area, used to evaluate reduction intraoperatively. We got postoperative image by CT or submento-vertex view. There are variable methods to evaluate reduction intraoperatively: palpation, ultrasonography, CT, plain films. C-arm is considered superior diagnostic tool to other methods. The use of intraoperative C-arm was very efficient, it could bring better results.
This study was based on a series of 369 patients with Oral and Maxillofacial injuries treated at Kumi Hospital, College of Medicine, Soon-Chun-Hyang University from Jan. 1992 to Dec. 1994. The results obtained were as follows : 1. The number of male patient was 310 and that of female was 59, leading to 5.3 : 1 of male-female ratio, and the 3rd decade was the highest age group in incidence. 2. Weekly incidence was the highest in Sun. & Sat. and monthly incidence was the highest in Nov.& Oct. 3. Causes as follows : traffic accident 41.9%, slip& fall down 25.4%, human trouble 16.5%, industrial accident 7.5%, sports 6.7%, etc. 4. Site distribution as follows : mandible fracture 32.3%, maxilla fracture 4.8%, zygoma fracture 21.4%, nasal bone fracture 34.1%, orbital& ethmoidal fracture 4.6%. 5. The most common site of mandible was symphysis & angle, and the ratio of OR & CR was 1.3 : 1. 6. The most common site of maxilla was Le Fort 1, 2, and the ratio of OR & CR was 3 : 1. 7. The most common site of zygoma was body, the ratio of OR & CR was 3.3 : 1. 8 . The mean period of intermaxillary fixation was 4.33weeks. 9. Combined injury in facial fracture was 35.8% : The facial fracture were most frequently combind with head & neck(47.0%), upper extremities and abdomen(9.8%). 10. The mean elapsed time from injury to hospital was 1.9days, and that to operation was 5.1days. 11. The mean number of combined teeth injury was 0.6, and percent of combined soft tissue injury of face was 51.3%. 12. Post-operative complication occurred in 4 out of 323 cases. all of that was infection.
Purpose: Reduction malarplasty is one of the common aesthetic procedures performed in the Orient. We have analyzed effective operative methods according to the pivot point for the osteotomy and reposition of the zygoma for reduction malarplasty after confirming the shapes of the individual zygomas. Methods: Thirty-six patients had been received malarplasty over the last 10 years. The average follow-up period was 16 months. We categorized the patients into three groups according to their prominent appearance features. Group I had a prominently protruded zygomatic body, group II had a prominently protruded zygomatic arch, and group III had a prominently protruded body and zygomatic arch. In the group I, two parallel oblique osteotomies on the body, the middle portion was removed, and with the zygomatic arch as the pivot point, the body was repositioned inwards. In the group II, the zygomatic body and arch osteotomy is performed, with the body as the pivot point, and the arch is depressed medially. In the group III, using the two aforementioned methods, the zygoma was repositioned medially. In each case, postoperative complications and patients satisfaction over the surgery were surveyed. Results: Each group had 25, 5 and 12 patients respectively. No significant complications were found except for one patient who experienced a non-union of zygomatic bone. In the case of group I, four patients underwent a secondary operation. Conclusion: Reduction malarplasty is popular as an effective facial contouring surgery. In order to obtain more effective results,however, the zygomatic shape should be identified, and appropriately repositioned by different operative technique according to pivot points.

Background Zygomaticomaxillary complex (ZMC) fractures mostly occur in the form of tripod fractures. The surgical field is accessed using a combination of three classic approaches. However, the subciliary incision may have unfavorable aesthetic results. Herein, the authors report the advantages of the extended transconjunctival approach (ETA) combined with T-bar screw reduction in minimizing scarring and complications for the treatment of ZMC fractures. Methods A total of 26 patients underwent ZMC reduction through the ETA and intraoral approach. A skin incision measuring roughly 5 to 8 mm in length was placed following the lateral canthal skin crease. After releasing the inferior crus of the lateral canthal tendon for canthotomy, the medial periosteum of the lateral orbital rim was preserved for canthal reattachment. A limited subperiosteal dissection and partial relaxing incision of the orbicularis oculi were performed to expose the fracture line of the inferior orbital rim and zygomaticofrontal suture. Reduction was performed using a T-bar screw through the transconjunctival incision and an elevator through the intraoral incision. Results The aesthetic and functional results were excellent. Successful reduction was achieved and the skin incision was less than 8 mm in 20 cases (76.9%). Only six patients had an additional skin incision (less than 5 mm) to achieve reduction. No cases of ectropion, entropion, or excessive scarring were noted. Conclusions The ETA using a T-bar screw is a useful method for maximizing aesthetic results in ZMC fractures, with the advantages of minimal scarring, faster recovery, and maintenance of pretarsal fullness.
