The nose is the most 3-dimensional structure located on the central area of the face. Rhinoplasty using autogenous tissues and alloplastic materials has been performed for augmentation of nasal tip and dorsum in Asia. For batten graft, spreader graft, columellar strut and/or tip plasty, autogenous tissue especially nasal septal cartilage is very useful. Sometimes surgeon is faced to the situation when usable septal cartilage is too small so other tissues or materials are needed during the operation. The purpose of this study is that we should predict the amount of obtainable septal cartilage by variant measurements of the nose and investigated relationship each other. From December 2002 to February 2004, on the 31 cases that operated rhinoplasty using septal cartilage, we took variable measurements such as nasal length, tip width, nasal basal width, nasal height, columellar width and length of nostril long axis preoperatively. Then we investigated the relationship with amount of actual harvested septal cartilage. As a result, the nasal length was the most correlated with cartilage amount statistically and tip and base width were correlated as well. In this study we concluded that nasal length was the most indicating parameter to predict amount of septal cartilage.

Facial scar is very stressful for patients and physicians, especially in the case of non-parallel to relaxed skin tension line (RSTL). In general, for long facial scar not parallel to RSTL, Z-plasty or W-plasty has been performed to change the direction of scar or divide it into multiple segmented scar. These methods would be suboptimal, however, in the instance of Asian skin prone to scar formation. So, we experienced good results for scar revision through scar excision and solid subcutaneous- dermal repair to minimize scar widening despite of leaving linear type of scar. From July 2004 to March 2007, our methods were undergone for facial scar longer than 3cm in 84 patients. All scars were excised along the scar margin and subcutaneous tissue and dermis were repaired using single layer of subcutaneous-dermal stitch with 4-0 or 5-0 PDS to elevate wound margin 3-4mm higher than adjacent skin surface. Skin was repaired with 6-0 Prolene. The rate of satisfaction was over 89%(75 of 84 patients), the mean scar widening was 0.61±0.20 mm, and secondary operations were made in 3 patients. The Asian skin has some characteristics such as thick skin, increased melanin, energetic proliferation of fibroblast, and vigorous collagen formation, etc. Because of characteristics of Asian skin mentioned above, the linear pattern repair, technically easier than Z-plasty or W-plasty, would be superior to them in terms of the results. The essentially important point for scar revision in linear pattern is very strong subcutaneous-dermal repair to make elevation of wound margin enough for tolerating the skin tension and preventing scar widening.

Background: The ultimate goal of craniofacial reconstructive surgery is to achieve the most complete restoration of facial functions. A bioabsorbable fixation system which does not need secondary operation for implant removal has been developed in the last decade. The purpose of this study is to share the experience of authors and to demonstrate the efficacy of bioabsorbable mesh in a variety of craniofacial trauma operations. Methods: Between October 2008 and February 2015, bioabsorbable meshes were used to reconstruct various types of craniofacial bone fractures in 611 patients. Any displaced bone fragments were detached from the fracture site and fixed to the mesh. The resulting bone-mesh complex was designed and molded into an appropriate shape by the immersion in warm saline. The mesh was molded once again under simultaneous warm saline irrigation and suction. Results: In all patients, contour deformities were restored completely, and bone segments were fixed properly. The authors found that the bioabsorbable mesh provided rigid fixation without any evidence of integrity loss on postoperative computed tomography scans. Conclusion: Because bioabsorbable meshes are more flexible than bioabsorbable plates, they can be molded and could easily reconstruct the facial bone in three dimensions. Additionally, it is easy to attach bone fragments to the mesh. Bioabsorbable mesh and screws is effective and can be easily applied for fixation in various craniofacial trauma reconstructive scenarios.

Purpose: The congenital epulis is a rare, benign tumor. It can protrude out of the newborn’s mouth to prevent normal closure of the mouth and it can interfere with respiration or feeding. Methods: An 11-day old female neonate presented with a 1.5×1.5×2.3cm sized mass in the gingival and anterior alveolar ridge of the mandible. We performed a simple excision. Results: In our case, histologically, there was no pseudoepitheliomatous hyperplasia. The staining for S-100 protein, and actin was negative. After 8 months, the patient had normal teeth eruption and no recurrence of the tumor. Conclusion: With early detection and appropriate treatment, we were able to help the baby avoid developing any dyspnea. Nursing was possible after the mass had been removed.

이차 구순비 변형 환자에서 Spacer Graft를 이용한 콧방울뒤당김 (retracted ala)의 교정

한규석,최현곤,신동혁,김순흠,황은아,엄기일 대한성형외과학회 2011 Archives of Plastic Surgery Vol.38 No.4

Purpose: In patients with unilateral cleft lip and nose deformity, alar retraction is commonly seen on the non-cleft side after cleft side is corrected. Spacer graft was used to drag down the inferior border of the alar cartilage of the non-cleft side so as to match the cleft side. By performing spacer graft and septal extension graft together, symmetry and cosmetic improvements were achieved. Methods: Seven unilateral cleft lip and nose deformity patients underwent surgery for alar retraction correction. The median age was 24 years (ranged from 15 to 34 years), and the median follow-up period was 7.4 months (ranged from 6 to 12 months). The perpendicular length from the longitudinal axis of the nostril to the alar rim, the nasolabial angle and the ala-labial angle were measured in the lateral view photo. The longest perpendicular length from the cephalic border of the alar rim to the parallel line of the alar base was measured in the frontal view photo. Results: Improvement in alar retraction was seen after the surgery. There were no specific complications during the follow-up and the symmetry of both nostrils was satisfactory. No increase in the nasolabial angle or exposure of the nostrils was seen after the tip projection via tip plasty. Conclusion: The fundamental factor in correcting alar retraction with secondary cleft lip and nose deformity is repositioning the alar rim with spacer graft, which seems to be more physiologic than other methods. The method combining spacer graft with septal extension graft will bring symmetry as well as more cosmetic improvement in correction of alar retraction with secondary cleft lip and nose deformity.

A Review of Subbrow Approach in the Management of Non-Complicated Anterior Table Frontal Sinus Fracture

김지남,최현곤 대한두개안면성형외과학회 2016 Archives of Craniofacial Surgery Vol.17 No.4

Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are controversial. The subbrow approach enables accurate reduction and internal fixation of the fractures in the anterior table of the frontal sinus by allowing direct visualization of the fracture. Given the surgical success in reduction and rigid fixation, patient satisfaction, and aesthetic benefits, the transcutaneous approach through a subbrow incision is superior to other reduction techniques used in the management of an anterior table frontal sinus fracture.

Background: This study was conducted to determine the effect of the distributional relationship between dental roots and the mandibular bone on single mandibular bone fractures, which are common craniofacial fractures. Methods: This was a retrospective, single-center study in Seoul, Korea. Patients with single mandibular fractures in the symphysis, parasymphysis, body, and angle area, with tooth structure involvement were included. The control group included patients with simple, bone-level lacerations without fractures. In total, 94 patients (72 males and 22 females) were included in the treatment group, and 125 (71 males and 54 females) were included in the control group. The height of the mandibular bone and the dental root were measured with panoramic radiography. The central incisor represented the symphysis area, the canine represented the parasymphysis area, the first molar represented the body area, and the second molar represented the angle area. Results: In the treatment group, symphysis fractures occurred in 16 patients (17%), parasymphysis fractures in 36 patients (38%), body fractures in 17 patients (18%), and angle fractures in 25 patients (27%). The ratios of the dental roots to the total height of the mandibular bone in the treatment group were 30.35%, 39.75%, 39.53%, and 36.27% for symphysis, parasymphysis, body, and angle areas, respectively, whereas in the control group, they were 27.73%, 39.70%, 36.76%, and 35.48%. The ratios of the treatment group were significantly higher than those of the control group. Conclusion: The results show that the higher ratio of the dental root to the height of the mandibular bone increases the fracture risk.
