  • Unilateral bony ankylosis of temporomandibular joint is not extremely rare. Treatment in all cases should be surgical. Considerable difficulty has been encountered by surgeons in the judgment of the planning of the treatment for anklosis; either by gap arthroplasty or by interposition arthroplasty. A recent review of the literautre reveals that many authors reported more of the interposition arthroplasty treatment because of no recurrence and the excellent results obtained. This 22-year-old Korean female, who had suffered from unilateral temporomandibular joint recurrent anklosis, was received an operation of ramus osteotomy followed by interpositional arthroplasty with using of thin gold plate. She formerly was received condylectomy twice at the age of 8 and 9, under the diagnosis of unilateral bony ankylosis due to trauma. My experience with alloplasty in unilaterally recurrent ankylosed T-M joint is presented here for her general and oral functional condition proved to be satisfactory after 4 years follow-up.

  • AVMs is not a neoplasm, but a congenital developmental anomalies.$^{5)}$ In oral and maxillofacial area, the high recurrence rate and more facial disfigurement give a difficult problem to surgen and patient.$^{8)}$ Conventional treatment modality nowadays is presurgical embolization and surgical resection. In treatment planning, we consider the possibility of complete surgical resection and the esthetics of soft tissue reconstruction. But, two things are very difficult to achieve. We present a patient with AVMs in left upper lip, he had presurgical embolization with Ivalon and Bucrylate, and conservative surgical procedure. So we present this possible treatment modality.

  • Prosthodontic treatment planning for various edentulous arches is not an easy issue for dentists. Especially, in case of removable partial denture, we must have a knowledge of overall treatment procedures, and a careful approach is needed. Recently, interest of dental implant and case reports are increasing, the decrease of the removable partial denture is true, but dental implantation takes longer treatment period and it is more expensive. Also, there are still some limitations like lack of available alveolar bone, patient's general condition, and chronic periodontitis. Therefore, sometimes implantation is impossible. Finally, implantation cannot be adapted to every single patient. Currently, the clasp type removable partial dentures are used routinely, giving patients many unesthetic and functional difficulties. With better laboratory technique, removable partial denture with attachment and removable partial denture in rigid type increase patient's happiness level much more than predicted. The case presented in this article, clinically demonstrate the efficiency of using a telescopic system to improve esthetic and functional recovery for patients who lose multiple teeth.

  • A Klystron powered dual photon energy electron linear accelerator 2300 C/D from Varian Associates has been installed in our center. From the radiological safety view as well as treatment planning, the output (contamination) of Bremsstrahlung Radiation with electron beam energy determined accurately. It has been found 0.5% to 4.7% with increasing the electron beam energy which is the clinically not much significant in the treatment of the malignant diseases with the treatment of electron beam.

  • Heavy ion and proton therapy necessitate range weeks, which are time consuming. Three types of variable compensator, membrane type liquid variable compensator, are proposed by some of the authors to overcome the difficulties, by those arbitrarily thickness distribution of compensator obtained from treatment planning is created at the site of treatment. None of the ideas, however, is yet realized. In this research, we are trying to construct prototype membrane-type liquid variable compensator. This variable compensator partitions air and liquid with elasticity membrane and changes the surface of the elasticity membrane with the thread. The air and oil move through holes to and from the out of beam side of two boxes in which they are contained. The boxes are made of Plexiglas(PMMA), the thread which is made of nylon, the elasticity film which is made from latex for the moment.

  • The spaced dentition is a common clinical finding. The careful analysis of clinically spaced dentition is a necessity for effective treatment planning. Spaced dentition often exists in the presence of intact teeth. Therefore, special care should be taken in order to obtain the most successful esthetic effect and to prevent overtreatment as well. The aesthetic restorative dental treatment using the porcelain laminate veneers is getting more popular than the complex orthodontic treatment, and prosthetic solutions that require sacrifice of sound tooth structure. The physical strength of porcelain laminate veneers is not as good as porcelain fused metal crowns, and more researches are needed in the field of bonding between composite cement and porcelain laminate veneer. However, the esthetic results from this unprepared porcelain laminate veneers were satisfactory with Authentic (Ceramay, Germany) pressable ceramic technique and resin cement (Rely X Veneer, 3M). This article deals with 2 cases of unprepared porcelain laminate veneers on anterior teeth.

  • Bilateral vocal cord palsy (BVCP) present a challenging condition which result from various etiologies including iatrogenic recurrent laryngeal nerve injury, progressive neurological disorder, intubation, trauma, tumor and idiopathic cause. Careful history taking, laryngoscopic evaluation, laryngeal EMG, and imaging studies are helpful for providing a precise diagnosis and planning appropriate treatment. BVCP causes airway restriction and not vocal dysfunction. In patients with BVFP, treatment is directed at maximizing the airway, while attempting to limit the negative effects of treatment on vocal function. A variety of surgical procedures are available for mangement of BVCP. The most conservative, limited procedure should be selected initially, and then further surgery and more extensive surgery can be tailored to the patient's airway and voice needs. This review will address the etiology, diagnosis, and managements of BVCP.

  • Objectives This study aimed to provide a basis for treatment of soyang person by investigate published case series of soyangin Methods We have reviewed case series of soyangin in the Journal of Sasang Medicine from 2007 to 2016. Results A total of 16 case series related to soyangin were reported. Among them, herbal medicine was used in 16 papers (100.0%), of which 'Hyeongbangjihwang-tang' was the most frequently used, reported in five papers (31.3%). For acupuncture of 12 papers (75.0%), acupoint 'ST36' was the most frequently used, reported in four papers (33.3%). Conclusions Most of the included case series were effective in treating patients of soyangin. However, the number of papers was insufficient to suggest standardized treatment for "diseases-Sasang medicine pattern-treatment" systems.

  • We develop an automatic imaging matching technique for combining portal image and simulator image for improvements in localization of treatment in radiation therapy. Fusion of images from two imaging modalities is treated as follows. We archive images thxough a frame-yabber. The simulator and portal images are edge detected and enhanced with interpolated adaptive histouam equalization and combined using geometrical parameters relating the coordinates of two image data sets which are calculated using Fourier descriptors. We don't use any kind of imaging markers for patient's convenience. clinical use of this image matching technique for treatment planning will result in improvements in localization of treatment volumes and critical structures. These improvements will allow greater sparing of normal tissues and more precise delivery of energy to the desired irradiation volume.
