Purpose: Well vascularized pectoralis major myocutaneous flap (PMMF) had been a commonly used versatile flap in reconstructive oromaxillofacial surgery since the 1970s. However, after the advent of microvascular surgery in the 1980s, the PMMF was used less frequently. But, to date, PMMF has been useful and has some advantages such as covering wide defects, covering vital structures, back-up procedure in cases of free flap failure, and reconstruction for radiotherapy patients. The purpose of this study is to evaluate the role, indication, complications, functional, and aesthetic results of this flap in the era of free flap with a literature and chart review. Methods: A retrospective study was conducted of 16 oral cancer patients undergoing reconstructive surgery with PMMF for reconstruction of defects from 2001 to 2012 at Kyungpook National University Hospital. The male to female ratio was 10:6, with a mean age of 63 years (16~79 years). Basic demographic data, previous treatment history, indications, dimension of the flap, site of reconstruction, postoperative complications, and patients' final status were systemically analyzed from chart review. Results: The pathology of the disease included squamous cell carcinoma in the majority of cases (n=14). The remaining cases were fibrosarcoma and mucoepidermoid carcinoma. Of the 16 PMMF reconstructions, 13 flaps were applied as primary reconstructive procedures, whereas three flaps were; salvage; procedures (vascularized free flap failure). Twelve patients had complications such as wound dehiscence, infection, hematoma, fistula, flap bulkiness, and partial flap necrosis. The higher complication rates showed an association with utilization of the flap in preoperative radiotherapy cases. However, all patients were discharged without failure. Conclusion: In reconstructive oromaxillofacial surgery, the PMMF is still a useful flap for huge defects. In addition, the PMMF can be used as a salvage procedure after vascularized free flap failure and reconstruction for patients with a history of preoperative radiotherapy.

Purpose: For reconstruction of craniomaxillofacial defects caused by tumor, trauma, infection etc, free flap transplantation with microvascular surgery is a very useful method. Thrombus formation at the anastomosis site is the major cause of graft failure. 4-Hexylresorcinol (4-HR) is generally known as an antiseptic and antiparasitic agent. This study was conducted in order to evaluate the effect of 4-HR on blood coagulation in vitro. In addition, we investigated thrombus formation and endothelial repair of an injured vessel in an animal model. Methods: In the in vitro experiment, we compared blood coagulation time between the 4-HR treated group and normal blood. Thirty rats were used for in vivo animal experiments. After exposure of the right femoral vein, a micro vessel clamp was placed and the femoral vein was intentionally cut. Microvascular anastomosis was performed on all rats using 10-0 nylon under microscopy. The animals were divided into two groups. In the experimental group (n=15), 4-HR (250 mg/kg) mixed with olive oil (10 mL/kg) was administered per os daily. Animals in the control group (n=15) were given olive oil only. The animals were sacrificed at three days, seven days, and fourteen days after surgery and rat femoral vein samples were taken. Vascular patency and thrombus formation were investigated just before sacrifice. Histologic analysis was performed under a microscope. Results: Results of an in vitro blood coagulation test showed that coagulation time was delayed in the 4-HR treated group. The results obtained from an in vivo 4-HR administered rat model showed that the patency of all experimental groups was better at thirty minutes, seven days, and fourteen days after microvascular anastomosis than that of the control group at seven and fourteen days after anastomosis, and the amount of thrombus in the experimental groups was much less than that of the control group. Endothelial repair was observed in the histologic analysis. Conclusion: Findings of this study demonstrated that blood coagulation was delayed in the vitro 4-HR treated group. In addition, good vascular patency, anti-thrombotic effect, and repair of venous endothelial cells were observed in the vivo 4-HR administered rat group.

DOI : 10.14402/jkamprs.2013.35.5.294
Purpose: The purpose of this study is to assess the effectiveness of beta-tricalciumphosphate (
-TCP) as a bone graft material on new bone formation and regeneration of mandible bone defect around dental implants. Methods: Both mandibular sites of ten rabbits were exposed. The experimental subjects were divided into two groups. Rabbits in the control group (right site of the mandible) had dental implants around cortical bone defects, without treatment, while, in the experimental group (left site of the mandible),
-TCP was grafted into the bone defect around the implant. Rabbits were sacrificed after one, two, three, four, and eight weeks, and histomorphometric evaluation and analysis of the bone implant contact rate were performed using an optical microscope. Results: Bone formation rates in the experimental group were greater than those in the control group from one to eight weeks, and percentages of implant surface contacted to bone were greater in the experimental group than in the control group from three weeks after implantation. Conclusion: These results suggest that the bone formation activity around dental implants was increased by osteoconduction activity of

DOI : 10.14402/jkamprs.2013.35.5.302
Purpose: This study evaluated the prognosis of conservative and surgical treatment according to the staging of bisphosphonate-related osteonecrosis of jaw (BRONJ) by American Association of Oral and Maxillofacial Surgeons and American Society for Bone and Mineral Research. Methods: We evaluated 53 patients of BRONJ who visited Department of Dentistry, Ajou University School of Medicine from May 2007 to February 2013. Twenty eight patients in stage 2, were divided into surgical and conservative groups with cessation of bisphosphonate therapy. Fifteen patients belonged to the conservative treatment group, in which mouth rinsing and antibiotics medication were done. Thirteen patients were treated with debridement or sequestrectomy, in the surgical treatment group. Each study list was analyzed by SPSS ver. 14.0 (SPSS Inc., USA) software and the favorable rate was verified by the Fisher exact test. P-values less than 0.05% were deemed significant. Results: Clinical outcome was evaluated on the basis of both clinical and radiographic findings. Of all the 28 patients of stage 2, 15 patients underwent conservative treatment and 13 patients received surgical treatment. In the surgical group, 9 of 13 (69.2%) showed good prognosis, 4 of 13 (30.7%) showed recurrence. In the conservative group, 13 of 15 (86.6%) showed no change duting the follow-up period. Two of 15 patients even showed a bad prognosis, such as pain and pus discharge, which are criteria for stage 3. P-value was 0.067 (>0.05). Conclusion: The results of the present study suggests that surgical intervention is good choice against the conservative treatment, after proper drug holidays period, while further investigation is needed for a definite solution to BRONJ.

Micromorphometric and histological examinations were conducted with a collected tissue specimen nine months after sinus bone graft using autogenous tooth bone graft material (AutoBT). As a result of micro-computed tomographic analysis, the total bone volume (graft material+new bone) was 76.45%, and the proportion of new bone was 45.4%. The bone mineral density and the average Hounsfield Unit of new bone were 0.26 and 1,164.69, respectively. The histological examination showed that AutoBT particles were united well with new bone. AutoBT was considered to have excellent bone healing ability after sinus graft and bone density that can resist repneumatization.

This case report describes the treatment of a 23-year-old woman who had lip protrusion with gummy smile and mentalis muscle strain. Orthognathic surgery was performed in conjunction with orthodontics. Minimum dental decompensation was performed with presurgical orthodontics followed by an anterior segmental osteotomy for the majority of dental decompensation. Counterclockwise rotation of the maxillomandibular complex was applied by LeFort I osteotomy, and bilateral sagittal split ramus osteotomies with anterior segmental osteotomy to achieve overall facial balance. The active treatment period was 15 months. Stable occlusion and skeletal relationship were observed after a 10-month follow-up period.

The patient's appearance can be dramatically enhanced as a result of orthognathic surgery. However, esthetic contouring of the mandibular body portion is often overlooked in the surgery. Restoring a more beautiful jaw line is important and directly affects surgical results. From December 2010 to February 2012, we performed mandibular body contouring for the slimming of the third lower part of the face in 37 patients who had undergone either 1-jaw surgery or 2-jaw surgery. The third lower part of the facial contour was improved in all the patients after at least 3 months follow-up. Mandibular body contouring is a simple method that can be additionally used for the slimming of the third lower part of the face in patients who require orthognathic surgeries. It makes the lower face look more attractive from both the anterior and lateral perspectives.

Maxillary sinus membrane elevation and bone graft have been performed routinely in alveolar bone with insufficient residual bone height. There are a number of causes for development of maxillary sinusitis after these procedures. When maxillary sinusitis is caused by sinus membrane elevation, bone graft, and implant placement, various treatment such as medication, incision and drainage (I&D), implant removal, and the Caldwell-Luc procedure can be considered. Removal of an implant or the Caldwell-Luc procedure can be harmful if inflammation is not present in the oral cavity and survival of grafted bone and implant osseointegration can be expected despite the presence of maxillary sinusitis. In this case, functional endoscopic sinus surgery, which was often used in the otorhinolaryngology department, was performed without removal of the implant for a patient with maxillary sinusitis after one month following implant placement. Thus, we report on this case with a review of the literature.

Fibrous dysplasia is a chronic developmental disease of the skeleton involving formation of immature bone. Involvement of facial bones can result in deformation of facial contour. Prominent cheek area is often treated with malarplasty, which has a variety of modifications, depending on the surgeon's preference. The authors report on a case of polyostotic fibrous dysplasia in which the patient's right cheek had a prominent appearance. The prominence was corrected with malarplasty without internal fixation. The soft nature of bone involved in fibrous dysplasia could provide greater flexibility for modification of the traditional surgery.

Advances in immunosuppressive treatments and microsurgical techniques have rendered composite tissues allotransplantation (CTA), such as heteregeneous or non-organ tissues, possible in humans. CTA has evolved dramatically since the first successful rat hind limb allotransplantation. Numerous clinical applications including face, hand, trachea, larynx, and vascularized joint have been performed. Although composite tissue allografts are still in their infancy, they have opened a new era in the field of transplantation surgery and pathology, so that maxillofacial reconstructive surgeons may occasionally be faced with the challenge of diagnosing skin refection of a composite tissue allograft. Facial allotransplantation (FAT) is a new surgical technique that could be considered as a new paradigm in facial reconstruction. Since the first human FAT had been achieved in 2005, 17 cases have been reported in the world up to date. However, many problems such as life-long immunosuppression, immune rejection, ethical problems and psychological problems are remained, so facial CTA is new reconstructive option with no general acceptance. The authors reviewed the indications, the results of 17 cases and their complications, and additional consideration factors in this article, and intended to raise the awareness of oral and maxillofacial surgeons in this type of facial transplantation.
