Background A cartilage wedge block and covering flap are standard procedures for firm elevation of the ear in microtia correction. However, using costal cartilage for elevation of the reconstructed auricle can be insufficient, and the fixed cartilage wedge block may be absorbed or may slip out. Furthermore, elevating covering flaps is time-consuming and uses up fascia, a potential source of reconstruction material. Therefore, we propose an innovative method using autologous onlay rib bone graft for auricular elevation of microtia. Methods From February 1995 to August 2012, 77 patients received a first stage operation with a rib cartilage framework graft. In the second stage operation, a small full thickness of rib bone was harvested through the previous donor scar. The bihalved rib bone was inserted into the subperiosteal pocket beneath the cartilage framework. Results The follow-up time ranged from 1 month to 17 years, with a mean of 3 years. All of the patients sustained the elevation of their ears very well during the follow-up period. Donor site problems, except for hypertrophic scars, were not observed. Surgery-related complications, specifically skin necrosis, infection, or hematoma, occurred in 4 cases. Conclusions Onlay rib bone graft used to elevate the reconstructed auricle is a more anatomically appropriate material than cartilage, due to the bone-to-bone contact between the bone graft and the temporal bone. Postoperative minor correction of the elevation degree is straightforward and the skin graft survives better. Therefore, reconstructed auricle elevation using onlay rib bone graft is a useful and valuable method.

Purpose: The goals of cranioplasty are to protect the brain from trauma and restore normal cranial contour with as few complication as possible. In patient who suffered from cranial defect, the most satisfactory form of cranioplasty may be archived with autogenous bone grafts. We report on the treatment of large frontal bone defect using pericranial flap and split-rib graft. Methods: A 29-year-old male was referred to our department. He was involved in an automobile accident resulting in large frontal bone and sinus defect and skull basal defect. The reconstruction was undertaken using galeal frontalis myofascial flap and split-rib cranioplasty using bicoronal incision. Results: The postoperative course was successful. For 9 months follow up period, there was no complication about hematoma, infection, CSF leakage and washboard deformity. He was pleased with the results even when absolute symmetry was not achieved. Conclusion: We experienced large frontal bone and sinus defect and skull basal defect patient and successfully treated with split-rib graft and galeal frontalis myofascial flap.

Purpose: Reconstruction of microtia using costal cartilage graft is commonly used technique nowadays. The chest wall depression at the donor site after the graft, however, has been noticed in many articles. Prevention or correction technique for the depression at the donor site also has been reported and we also have been concerned about the problem. This article is a case report about a new technique preventing chest wall depression after costal cartilage graft. Methods: We selected total 15 microtia patients who visited our clinic, from December 2005 to July 2007. They were 10 male and 5 female patients and the mean age was 11.9 years. The average follow up period was 9.2 months(2 to 15 months). We used 6, 7, and $8^{th}$ costal cartilage for microtia reconstruction. And then we turned over pivot of cartilage resection margin, after bihalving costal cartilage involving about 5-6 cm of $6^{th}$ and $7^{th}$ rib bone. After microtia reconstruction, chest donor sites were evaluated by physical examination and radiography. Results: Postoperative depression at the donor site was much less when the costal cartilage turnover technique was performed. Postoperative physical examination and three dimensional reconstruction CT showed that the rest part of rib bone was turned over and it supported the soft tissue defect during respiration. Conclusion: We expect that the turnover rib bone will not be absorbed after graft, as well as offering mechanical support, compared to the other reports.

Background: We evaluated and compared the outcomes of different ossification processes in patients with alveolar cleft in whom correction was performed using endochondral bone graft or intramembranous bone graft. Methods: The patients were divided into two groups: the endochondral bone (iliac bone or rib bone) graft group and the intramembranous bone (mandibular bone) graft group. Medical records and radiologic images of patients who underwent alveolar bone grafting due to alveolar cleft were analyzed retrospectively. Through postoperative and follow-up radiologic images, the height of the interdental bone septum was classified into four types based on the highest point of alveolar ridge. Then, the height of the interdental bone septum and the area of the bone graft were evaluated according to the type of bone graft. In addition, the occurrence of complications and the need for an additional bone graft, the result of postoperative orthodontic treatment, and the eruption of impacted teeth were investigated. Results: Thirty patients were included in this study. There was no significant difference in the change of the interdental bone height and the area of the bone graft according to the type of bone. There was no significant difference in the success rate of the surgery according to the type of bone. One patient underwent an additional bone graft surgery during the follow-up period. Conclusions: The outcomes of alveolar bone grafting were not significantly different according to the type of bone graft. If appropriate to the size of the recipient site, the chin bone is a useful graft material in alveolar cleft, as is the iliac bone.

Objectives: Oral and maxillofacial defects often require bone grafts to restore missing tissues. Well-recognized donor sites include the anterior and posterior iliac crest, rib, and intercalvarial diploic bone. The proximal tibia has also been explored as an alternative donor site. The use of the tibia for bone graft has many benefits, such as procedural ease, adequate volume of cancellous and cortical bone, and minimal complications. Although patients rarely complain of pain, swelling, discomfort, or dysfunction, such as gait disturbance, both patients and surgeons should pay close attention to such after effects due to the possibility of tibial fracture. The purpose of this study is to analyze tibial fractures that occurring after osteotomy for a medioproximal tibial graft. Materials and Methods: An analysis was intended for patients who underwent medioproximal tibial graft between March 2004 and December 2011 in Inha University Hospital. A total of 105 subjects, 30 females and 75 males, ranged in age from 17 to 78 years. We investigated the age, weight, circumstance, and graft timing in relation to tibial fracture. Results: Tibial fractures occurred in four of 105 patients. There were no significant differences in graft region, shape, or scale between the fractured and non-fractured patients. Conclusion: Patients who undergo tibial grafts must be careful of excessive external force after the operation.

The congenital condition referred as hemifacial microsomia is characterized by underdevelopment, malformation or abscence of certain soft and hard tissue derivatives of the first and second branchial arches and open also of structures which are not derived from the branchial arches, such as the zygoma, temporal bone. This is a report about a 14 years old male patient with the chief complaint of severe facial asymmetry, who was diagnosed as hemifacial microsomia having agenesis of the right mandibular condyle and zygomatic arch. Deformities and rib bone graft on the affected mandibular condyle and body, and LeFort I osteotomy in the maxilla. To correct contour-deficient chin, we performed the genioplasty, and the zygomatic arch was reconstructed with rib bone graft.

Surgical curettage or en bloc excision are the usual choice of treatment for osteoma. Local recurrence of osteoma after surgical treatment is not very common. We report a case of osteoma recurred at the grafted bone. A $5{\times}8cm$ sized osteoma of frontal bone was excised and then the defect was covered with calvarian bone and rib bone. Six years after reconstruction, recurrence from grafted area was noted. We completely removed the osteoma with enough normal tissue around it, after checking that the grafted bone has changed into an osteoma through a bicoronal incision. Then we covered the defect with a rib bone. The tissue was confirmed histologically as an osteoma. The recurrence of the tumor at the bone grafted site after osteoma excision is probably due to the fact that we covered grafted bone with periosteum left over osteoma. Therefore, we can learn that when we excise osteoma, galea should be carefully separated from the periphery of the tumor and that the periosteum should be completely removed, to prevent the osteoma from recurrence.

Background The radial forearm osteocutaneous free flap is considered to be the standard technique for penile construction. One year after their operation, most patients experience a softened phallus, so that they suffer from difficulties in sexual intercourse. In this report, we present our experience with phalloplasty by radial forearm osteocutaneous free flap, as well as an evaluation of the etiology and treatment of the softened phallus. Methods Between March 2005 and February 2010, 58 patients underwent phalloplasty by radial forearm osteocutaneous free flap. Most of their neophallus had been softened subjectively and among them, 12 patients who wanted correction were investigated. We performed repetitive fat injection, artificial dermis grafting, silicone rod insertion, and rib bone with cartilaginous tip graft. Physical examination, plain radiograph, computed tomography, bone scintigraphy, and satisfaction scores were investigated. Results Most of the participants' penises have been softened after phalloplasty, and the skin elasticity had been also decreased. On plain radiograph, the distal end of the bone was self-rounded; however, the bone shape of the neophallus had no significant interval changes or resorption. Computed tomography showed equivocal density of cortical bone. On bone scintigraphy, the bone metabolism was active at 3 months postoperatively, and remained active 9 years postoperatively. Conclusions The use of a rib bone with cartilaginous tip graft could be an option for improvement of the softened phallus. Silicon rod insertion is also worth considering for rigidity of the softened phallus. Decreased rigidity due to soft tissue atrophy could be alleviated with repeated fat injection and artificial dermis grafting.

From 1981 to 1991, twenty one vascularized bone grafts had been performed for the treatment of large bone defects of the extremities, with average follow-up of 65.4 months. Fibulae were used in 15 patients Including two cases of osteocutaneous flap, iliums in 5 including two of osteocutaneous flap, and osteocutneous rib in one. Ten of these patients were treated for segmental defects derived from trauma or infection sequelae of long bones, while eight for locally aggressive benign or malignant bone tumors ; and three for congenital pseudarthrosis of tibia. The location of the lesions were 8 cases in tibia; 7 in humerus ; 3 in forearm bone ; 2 in foot ; and 1 in femur. The length of bone defects were averaged as 10 cm, ranging from 3 to 17.5. In eighteen patients(85.7%), the operation was successful. The duration from operation to bony union was average 5.1 months on successful cases, and three of them needed additional procedures, such as bone graft and electrical stimulation to promote bony union. Local recurrence was found in one case of chondrosarcoma, resulting in AK amputation. Wound infections were noted each one case on donor or recipient site. In five cases, the fracture of grafted bone, which united with cast immobilization in four, occurred average 16.7 months after operation.
