Hemangioma and vascular malformation is a common vascular benign lesion in the head and neck region. The lesion is a congenital malformation observed in neonates. The treatment this lesion includes surgical excision, cryotherapy, selective embolization and treatment with sclerotic agents. We present three cases of benign oral vascular lesions treated with an intralesional injection of sodium tetradecyl sulfate. The lesions virtually disappeared after three sessions of sclerotherapy, leaving an inconspicuous scar. No side effects were observed. Sclerotherapy with sodium tetradecyl sulfate is effective in treating benign oral vascular lesions, and the use of the sodium tetradecyl sulfate provides alternative or support for surgical methods.

In order to make in vivo model of human oral squamous cell cancer, we brought up BALB/C nude mice in specially designed housystem, and maintained some kind of human oral squamous cancer cell lines ; KB, SCC-4, SCC-9, SCC-15, SCC-25. Various concentration of cancer cells were inoculated subcutaneouly into flank area of nude mice. We observed each nude mouse more than 5 weeks after tumor inoculation. We appraised the results, measured the tumor size, and calculated the growing tumor volumes after tumor inoculation according to cancer cell line and concentration of cancer cells in media. Some cancer cell lines were rapidly growing in nude mice, but some cancer cell line couldn't grow in nude mice and resorbed completely. And in some cancer cell line, some nude mice showed continuously growing tumor, but other didn't show any tumor growing. And as a new try, we implanted specially disigned caps on the back of nude mice, and cancer cell lines were brought into the caps with media. We removed the cap after 1 week, and observed over 4 weeks. The shape and size of growing tumor were observed.

When restoring with a dental digital system for implant-supported prosthesis, a double digital scanning technique is required: an intraoral scan of the three-dimensional implant location and intraoral scan after placement of temporary denture or provisional prosthesis. During the intraoral scan, the use of scan body as a stable landmark can improve the accuracy of digital impression and simplify laboratory process. In this case, a full-digital system was used to plan and fabricate a custom abutment, provisional prosthesis, and definitive prosthesis. After implant placement, the scan area of the intraoral scan body connected with implant and the intraoral scan body marked on the inside of temporary denture were superimposed. Out of the superimposed files, a custom abutment and provisional prosthesis were fabricated which match the vertical dimension of temporary denture, and definitive prosthesis was fabricated based on provisional prosthesis. We report this case because result has been functionally and esthetically satisfactory by using vertical dimension and central relation set during the fabrication of temporary denture to the definitive prosthesis.

IN 1956, Peer presented a very comprehensive account of free fatty tissue transplantation. The use of buccal fat pad had been usually used to reconstruct the perioral defects. The buccal fat pad is a special fatty tissue which is markedly different from subcutaneous fat. And it is a easily accessible fat tissue in oral and maxillofacial region. The buccal fat pad can be used as a free graft or pedicled flap. Recently, buccal fat pad is interested in cosmetic surgery because its' removal for cosmetic purpose has been favorable result. We used the buccal fat as an unlined, pedicled graft for closure of large oroantral fistula. We present a case of report and review of literature.

Currently dental laser is used at a variety of dental treatment and many favorable clinical case reports are presented. We performed this study for the presentation of the validity of dental laser which are available and supportable in the oral and maxillofacial surgery. From October, 1998 to March, 1999, dental laser was used in 70 cases. Male patients were 38, female 32. The age ranged from 5 to 77, with a mean of 45.4. Indicated cases were 18 chronic periodontitis, 11 infections, 6 atypical pain, malignant or benign tumor, precancerous lesion, abnormal frenum, TMJ disorder, mucocele, and so forth. $CO_2$ laser(Sharplan 15F, Sharplan Co.) was used in 40 cases, Ho-YAG laser(Duopulse 2000, Excel Co.) 11, Nd-YAG(Duopulse 2000, Excel Co.) 18. We present and discuss about the objectiveness, availability, and future application of laser with case reports.

중안면부의 골절은 심미적으로나 기능적으로 많은 문제를 야기할 뿐아니라 두개부와 연관되어 뇌손상의 가능성을 가지므로 생명과 직접적인 연관을 갖는다고 할수 있다. 산업사회의 고도의 발달로 인하여 자동차의 보급이 증가하고 그에 따라 교통사고의 절대수가 증가하고 안면부 골절환자가 증가추세에 있다고 볼 수 있다. 때문에 구강악안면외과의사로서 중안면부의 골절에 관심을 기울여야 할 것으로 생각된다. 중안면부 골절 가운데 비골을 포함한 안와 근심벽의 쉽게 일어나며 골절에 포함된 해부학적 구조물들이 복잡하기 때문에 골절후에 기능적 이상이 쉽게 발생될 수 있다. 본 과에서 처치한 중안면 골절 환자중 비골을 포함한 안와 근심벽의 골절환자를 경험한 바 이에 보고하는 바이다.

After the Iraq war, the Korean government established an Iraq Peace and Reconstruction Division, 'Zaytun'. Zaytun division has been dispatched in northern Iraq, since August 3, 2004. As one of our missions, 'Zaytun Hospital' was built to support the demand for the insufficient medical facilities and supplies in Iraq, which was opened on November 27, 2004. Zaytun Hospital, equipped with modern operation room and general ward, has been composed of 12 clinical departments. Although we had many problems, such as difficulty of communication with Iraqis, connection with medical facilities of Iraq and risk of terrorism, we overcame these difficulties and were able to achieve our missions successfully. I wish that our special experience in Iraq are will be the guideline to other oral and maxillofacial surgeons, who want to help those individual in unfortunate areas such as Iraq.

저자는 지난 1년간 서울대학교병원 치과진료부 구강외과에 래원한 아프타성 구내염 환자 10명에 대하여 한냉외과 시술과 보존요법으로 치료하여 창상치유 및 동통호소에 관한 임상적 연구를 하였던 바 다음과 같은 결과를 얻었다. 1. 보존적 치료를 받았던 아프타성 구내염 병소는 대체로 14일 후에 치유됨을 관찰할수 있었다. 2. 한냉외과적 치료를 받았던 아프타성 구내염 병소는 시술후 5~7일경에 치유되었다. 3. 보존적 치료를 받은 환자는 음식물 섭취시 대체로 7~10일간 동통을 호소하였다. 4. 한냉외과적 처치를 받았던 환자는 1일후부터 음식물 자극에 대하여 하등 동통을 호소하지 않았다.

Carbondioxide($CO_2$) laser is one of the most widely employed lasers in oral soft tissue surgery because of its excellent affinity for water based soft tissues. It has some inherent advantages such as hemostasis, less postoperative swelling, reduction of bacterial population at surgical site, less need for suturing, less scarring, and less postoperative pain compared to conventional surgical therapies including the use of scalpel, diathermy, cryotherapy and electrosurgery. A 30-years-old male was presented with gingival swelling. Clinical examination revealed a well?defined pedunculated fibrotic mass on the buccal gingiva near right maxillary 1st molar. In radiographic examination, no remarkable abnormality was seen. Excisional biopsy was performed with $CO_2$ laser (continuous wave mode, 4.0W). Histological diagnosis was "Irritation fibroma". $CO_2$ laser has advantages those are suitable for surgical treatment of intraoral lesion. If appropriate training and experience are provided, the dentist would be able to manage intraoral lesions more efficiently and successfully with the use of the $CO_2$ laser.

Osteogenesis imperfecta is a heterogeneous group of connective tissue diseases that is predominantly characterized by bone fragility and skeletal deformity. Two siblings with undiagnosed type I osteogenesis imperfecta underwent orthognathic surgery for the treatment of facial asymmetry and mandibular prognathism. The authors report two cases of combined orthodontics and orthognathic surgery in patients with type I osteogenesis imperfecta, mandibular prognathism, and facial asymmetry.
