Microgenia is that the mental protuberance is small state because of symphysis did not developed properly while occlusion and size of mandible are normal. One or two-step sliding advancement genioplasty is mainly performed to make good aesthetic harmony with face, but in slight or moderate degree of microgenia patients who do not want general anesthesia or osteotomy, the multiporous high-density polyethylene(Medpor(R)) can be used. It is easy to carve and bend, and has a variety of size and shape to fit the contour of the chin anatomy. Under the local anesthesia. a vertical incision which can preserve mentalis muscle is made about 2 cm at inferior labial sulcus along inferior frenulum in the jaw midline. Subperiosteal dissection is performed to make a pocket. Seperated Medpor(R)s are inserted in each side and reassembled into one in the midline. To minimize bone erosion, implant has to be placed on the inferior side of mandible edge and fixed with screw. Bandage compression was applied for 3 days and antibiotics was treated for 7 days postoperatively. This technique has a small incision, easy procedure and faster recovery. During the follow-up period, there were no specific complications and patients were all satisfied to their result.

The blow-out fracture can be reconstructed by various autogeneous and alloplastic material. Particulate, nonresorbable hydroxyapatite is currently one of the choice of implant material available for reconstruction of blow-out fracture. Hydroxyapatite is radiopaque ceramic, physically and chemically similar to enamel and cortical bone. It is a biomaterial derived from natural corals to use as a bone graft substitute. And we looked into the clinical usefulness of 2 type of hydroxyapatite with their advantages and disadvantages in reconstruction of blow-out fracture. 183 patients with blow-out fracture who underwent surgical reconstruction with two types of hydroxyapatite from March 1933 to July 1977 have been analyzed the results of surgical reconstructions, and have been followed up for more than a year. And the condition of formerly inserted hydroxyapatite was observed in the patients who needed 2nd surgical reconstruction due to the enophthalmos. The disadvantages of hydroxyapatite are fragility, size and contour limitations. In spite of these demerits, hydroxyapatite can be one of the prospective materials to reconstruct orbital floor. Through the clinical experiences for 5 years, we have not found any of complications of exposure, infection, and foreign body reaction. Low rates of diplopia, limitation of ocular movement, and enophtalmos was observed. Hydroxyapatite was well adherent to adjacent orbital bone in most patients who needed secondary reconstruction for enopthalmos. In conclusion, our study shows that the availability of hydroxyapattite in reconstruction of blow-out fracture is recommendable, with low complication rates. Hydroxyapatite important appears to be well tolerated, and provides useful alloplastic prosthesis with few problems in reconstruction of blow-out fracture.

Cutaneous polyarteritis nodosa (CPAN) is a form of necrotizing vasculitis of the medium and small-sized arteries. The condition is limited to the skin and there is a lack of visceral involvement. Treatment with systemic glucocorticoids alone or in combination with azathioprine, methotrexate or cyclophosphamide, depending on the disease severity, has been shown to be effective. This paper reports the clinical case of a 53-year-old female patient with CPAN refractory to treatment with high dose glucocorticoid, methotrexate, azathioprine, and cyclophosphamide, who was treated successfully with anti-tumor necrosis factor-α therapy (adalimumab).

BACKGROUND: The nasal septal cartilage is often used as a donor graft in rhinoplasty operations but can vary widely in size across the patient population. As such, preoperative estimation of the cartilaginous area is important for patient counseling as well as operating planning. We aim to estimate septal cartilage area by using facial computed tomography (CT) studies. METHODS: The study was performed using facial CT images taken from 200 patients between January 2012 to July 2015. Using the mid-sagittal image, the boundary of cartilaginous septum was delineated from soft tissue using the mean difference in signal intensity (or brightness). The area within this boundary was calculated. The calculated area for septal cartilage was then compared across age groups and sexes. RESULTS: Overall, the mean area of nasal septal cartilage was 8.18 cm² with the maximum of 12.42 cm² and the minimum of 4.89 cm². The cartilage areas were measured to be larger in men than in women (p<0.05). The area decreased with advancing age (p<0.05). CONCLUSION: Measuring the size of septal cartilage using brightness difference is more precise and reliable than previously reported methods. This method can be utilized as the standard for prevention of postoperative complication.

Behçet's disease is a systemic chronic disease that occurs in tissues such as eyes, joints, organs and nerves, and it has been noted that symptoms may be observed in a variety of tissues. In previous studies, reports of blepharoptosis observed in patients with Behçet's disease have been rare. We would like to report a case where a patient among those who visited our hospital with blepharoptosis had a history of Behçet's disease. This patient had been diagnosed with Behçet's disease, and complained of bilateral blepharoptosis even at the time of diagnosis. He complained of dysfunctions in vision and hearing, and upon eye examination, an eye movement disorder was found in his left eye. From the symptoms, neuro-Behçet's disease was diagnosed. The oculomotor and levator palpebrae superioris muscles are both controlled by cranial nerve III, which may suggest that Behçet's disease in this patient occurred in cranial nerve III. The patient received an oral steroid, and the symptoms have improved without surgery. Since we could identify the correlation between Behçet's disease and blepharoptosis, we considered that sharing this case and its outcome would be helpful for plastic surgeons who treat eyelids.

PURPOSE: Autologous platelet rich plasma (PRP) has been known to enhance tendon healing and improve tensile strength after tendon injury. This study investigated the dosage of PRP to increase the tensile strength. METHODS: PRP was harvested from peripheral bloods of the rabbits. Direct injury model was adopted using 60 achilles tendons in 30 rabbits. The autologous PRP was infiltrated into the Achilles tendon repair site of four groups (control, 0.1, 0.2, 0.4 mL) with different dosages. Tendons were harvested at 2, 4 and 8 weeks and subjected to measuring mechanical tensile strength and dosage of collagen content. RESULTS: At 2, 4, and 8 weeks, PRP administration following experimental achilles tendon repair resulted in an overall higher average tensile strength and collagen content compared to these of the control. Also, the lengthen the time, tensile strength and collagen content was increased. CONCLUSION: Autologous PRP enhanced tendon healing in rabbits. Within the PRP dosage setted by the author, more dosage of the infiltrated PRP increases the strength of the tendon and the dosage of collagen content. Further studies will be essential to determine the optimal dosage of PRP in clinical practice.

Despite the fact that benign skin lesions can undergo malignant transformation, the necessity and timing of the surgical resection have yet to be established. In this study, we analyse three cases of benign-appearing skin lesions, which were found to be carcinomatous on histologic examination and review the literature regarding the importance of prophylactic removal of benign-appearing skin lesion. The first and second cases were female patients wishing for cosmetic surgery. The first patient had a benign-appearing lesion on dorsum nasi, and the second patient had an inconspicuous lesion right along the right nasolabial fold. The third patient was a middle-aged male with a pigmented lesion on the left cheek, who presented to the clinic only after having met the operating surgeon through an acquaintance outside the hospital setting. All of the lesions were suspected to be of benign nature and were excised for cosmesis only. However, histologic examination of these lesions showed that the first two tumors were basal cell carcinoma with the last tumor being squamouse cell carcinoma. Thus, it is considered that removal of benign like skin lesion will result in good prognosis of patients scheduled to undergo other surgery.

We report two cases of cleidocranial dysplasia, which was managed without significant craniofacial osteotomy. A mother and daughter, both of normal intelligence, presented with central forehead depression, mid-face hypoplasia, and blepharoptosis. The fact that they have an identically deformed face implied a genetic basis. In both patients, radiologic evaluation revealed the underdeveloped maxilla, persistent fontanelle opening, and cleidal aplasia. Clinical findings and radiologic studies were consistent with the diagnosis of cleidocranial dysplasia. Both patients underwent forehead plasty via bicoronal approach, augmentation rhinoplasty using tip plasty, and epicanthoplasty. In addition, the mother underwent malar augmentation using Medpor implantation and reduction genioplasty. The patients did not experience any postoperative complication and remained satisfied with the operation at 6-year follow-up.

Total scalp avulsion is rare but a devastating injury. This condition burdens the patient with disfigured cosmetic appearance and permanent psychosocial trauma. Throughout history, this condition has been favored in women working with mechanics since the long hair function as a vector appliance for oblique pull of the hair into a stationary torque. We present our experience of the replantation of the total avulsed scalp in male, first to be reported in Korea. Warm ischemic time was exceeding 16 hours along with severe crushed condition of the detached margin, a relatively satisfactory result was obtained.
