Mandible defects could be caused by congenital malformations, trauma, osteomyelitis, tumor resection. If large areas are included for reconstruction, those are primarily due to tumor resection defects. The large jaw defect results in a problem about mastication, swallowing, occlusion and phonetics, and poor esthetics causes a lot of inconvenience in daily life. It is almost impossible to be a part underwent mandibular resection completely reproduced, should be rebuilt artificially. This case is of a patient who was diagnosed with squamous cell carcinoma pT1N0M0, stage I in February 2004 and received surgery (combined mandibulectomy and neck dissection operation (COMMANDO) in oromaxillofacial surgery) in March 2004, by implant assisted removable partial denture. We could obtain good retention and stability through sufficient coverage and implant holding. Follow up period was about four years. Mandibular left third molar regions have been observed to have resorption of surrounding bone, and periodic check-ups are necessary conditions.

편측 성대마비에 의한 부전의 수술적 치료로는 그 동안 테플론주입에 의한성대내측전위술, 제1형 갑상연골성형술, 또는 피열연골내전술 등이 이용되었으며, 성대부전이 심하거나 성대높이에 차이가 있을 때는 제1형 갑상연골성형술 등에 비해 피열연골내전술이 좋은 결과를 보이는 것으로 보고되고 있다 그러나, 성대의 움직임은 있으면서 뒷쪽에 심한 성대부전(posterior glottic chink)을 보이는 경우에는 아직은 특별한 수술적인 방법이 없는 바, 저자들은 갑상선 부분절제술 후에 생긴 양쪽성대의 움직임은 있으면서 성문 뒷쪽에 심한 부전을 보인 발성장애 환자 1례에서 제1형 갑상연골성형술과 동시에 피열연골내전술을 시행하여 좋은 결과를 얻었기에 보고하는 바이다.

Desmoid tumors are benign neoplasms with high rates of recurrence. A case of huge desmoid tumor of the intrathoracic and intraabdominal space is presented. The patient was treated with resection, which involved hepatic left lobectomy and diaphragmatic resection and partial pericardiectorny and wedge resection of left lower lobe of lung. The resulting defect over the pericarium and diaphragm was reconstructed by bovine pericardium and Marlex mesh. Prevention of presumed local recurrence of desmoid tumors requires wide excision margin.

Segmental mandibulectomy causes severe functional disability and cosmetic problem. Many methods of reconstruction have been used but none of these procedures provides the ideal solution. There has been increased interest in the possibility of preserving a portion of the mandible and still carrying out a adequate tumor resection. We experienced four cases of marginal with sagittal mandibulectomy in patients with floor of mouth. buccal. and soft palate carcinoma, and sagittal mandibulectomy in 8 patients with tonsillar carcinoma and a case of marginal mandibulectomy in tonsillar cancer patient. In all cases mandible facing the tumor were successfully resected and repair of the mandible. postoperative facial contour were satisfactory. We think. that these sagittal procedures are oncologically sound in its removal of tumor. biomechanically secure and maximize postoperative rehabilitation while maintaining the normal contour of the face.

제안된 연구에서는 기존의 일반 CT(Computerized tomography) 영상이 아닌 MDCT(Multi Detector CT) 영상을 이용하여 장기 추출에 관한 연구를 진행하였다. 조영제를 이용한 복부 MDCT 영상으로부터 모폴로지(morphology) 기법을 통해 간에 근접한 노이즈를 제거하고, 기존의 Otsu threshold를 개선하여 간의 명암값 분포를 구분할 수 있는 임계치를 구하였다. 찾아진 임계치를 이용하여 영상을 이진화하고, 최종적으로 위치정보를 이용하여 간에 해당하는 부분들을 추출하였다. 이러한 방식은 명암값과 위치정보를 이용하여 간을 추출한 후 다시 노이즈 문제를 해결하는 기존의 알고리즘과 비교했을 때, 처리 방식이 단순해지고 속도가 향상되었다. 추출된 간은 간 이식술이나 절제술에 필요한 간 내부의 혈관 인식과 간의 부분체적 계산 연구에 중요한 정보로 사용될 수 있을 것이다.

Defects due to mandibulectomy often cause hard and soft tissue loss and result in esthetic problems and functional disorders such as mastication, swallowing, and pronunciation. After the mandibular reconstruction, several complications including loss of alveolar bone can cause limitations in maintenance or supporting of removable prosthesis. For these patients, implant-supported fixed restorations have been an appropriate prosthetic restorative method. In this case report, we report the patient who underwent mandibulectomy and mandibular reconstruction owing to oral cancer, and then restored the current dentition functionally and aesthetically by applying zirconia frameworks and monolithic zirconia crowns by computer-aided design and computer-aided manufacturing.

Negative pressure pulmonary edema (NPPE) during anesthetic recovery is a rare, but potentially serious complication for patients who are undergoing different surgical procedures. The proposed mechanism is the generation of high negative pressure during markedly respiratory effort and upper airway obstruction from glottis closure and laryngospasm, and this all leads to pulmonary edema. We report here on a case of a healthy 26-year-old male who immediately developed NPPE and hemoptysis following extubation after partial rib resection due to benign rib tumor; the patient was treated conservatively. We also include a review of the review literatures.

Solitary fibrous tumor is an uncommon submesothelial mesenchymal neoplasm that primarily arises from the pleura. Most solitary fibrous tumors have a benign course, and the single most important predictor of the clinical outcome is the ability to excise the entire lesion. We experienced a case of CSF leakage through a subarachnoid-pleural fistula after resection of a malignant solitary fibrous tumor and the involved rib. We detected CSF leakage via performing CT myelography and we treated this case with hemilaminectomy and dura repair.

In Fibrous dysplasia(FD) of the jaws, the majority of cases can await the cessation of growth before surgical intervention, and it seems prudent to delay surgery whenever possible until growth has ceased. In craniofacial FD, however, the dangers of dystopia, dystopia and loss of vision may require early surgery to prevent or control cranio-orbital complications. Delaying surgery in those circumstances may be significantly detrimental to such patients. Conservative surgical management of FD is widely practised and we advocate an extension to this conservative treatment by combining surgical recontouring with appropriate osteotomies if indicated, to achieve an optimal esthetic and functional results in craniofacial FD. One case will be presented to illustrate the feasiblility of such combined treatment, to report the uneventful healing of osteotomies in the FD of the jaws, and to demonstrate the use of titanium miniplate fixation in dysplastic bone. The other case had expansile disease of the left facial and fronto-temporal bones and osteolytic change left mandible. This patient complained of severe spontaneous bleeding of left mandibular premolar area and it was suspected as central hemangioma of the left mandible and craniofacial FD. Angiogram disclosed generalized dilation of the external carotid artery and its branches, especially terminal branches of the left facial and inferior alveolar arteries. But no specific abnormalities, such as A-V shunt, venous lake, or early venous drainage, was seen. So it was diagnosed craniofacial FD with hypercellularity and generalized bony recontouring was performed via coronal and transoral approaches.

Maxillary bone defects may follow surgical treatment of benign and malignant tumors, trauma, and infection. Palatal defects often lead to problems with swallowing and pronunciation from the leakage of air into the nasal cavity and sinus. Obturators have been commonly used to solve these problems, but long-term use of the device may cause irritation of the oral mucosa or damage to the abutment teeth. Utilizing implants in the edentulous area for the fabrication of the obturators has gained attention. This case report describes a patient, who had undergone partial resection of the maxilla due to adenocarcinoma, in need of a new obturator after losing abutment teeth after long-term use of the previous obturator. Implants were placed in strategic locations, and an implant-retained maxillary obturator was fabricated, showing satisfactory results in the rehabilitation of multiple aspects, including palatal defect, masticatory function, swallowing, pronunciation, and aesthetics.
