Cleft palate is one of the most devastating congenital facial deformities frequently accompanied by cleft lip. In many cases, it causes phonetic and swallowing difficulties although surgical interventionwas applied. Among the surgical methods, Veau-Wardill-Kilner pushback palatoplasty (V-Y reposition) is widely used in the most cleft palate cases. It is designed to lengthen the palate posteriorly, hence to overcome the speech and swallowing problems, but broad postoperative palatal scar might interfere the normal maxillary growth. If the velar muscles were not reoriented, it could result in incomplete speech recovery. In this case report, the modified two-flap palatoplasty with minimal pushback was successfully applied to a 21 month-old girl who has had incomplete cleft palate extended to the posterior third of hard palate. The speech evaluation was confirmed as functional reconstruction of cleft palate was achieved.

편평태선은 면역 매개 점막피부 질환으로 병인은 여전히 알려져 있지 않고, 중년의 백인 여성에서 흔히 발생하고 구강점막에서 증상이나 징후가 생기기도 한다. 편평태선의 피부 병소는 가려움을 유발하나 자기 제한적이고, 구강편평태선의 구강 병소는 만성적이고 좀처럼 스스로 치유되지 못하고, 드물긴 하나 잠재적으로 전암 병소로 발전할 수 있다. 구강편평태선은 비록 비치태 연관 질환이나 통증, 출혈로 인해 적절한 치태 조절이 어렵게 되어 치태 연관 질환을 야기할 수 있고, 작열감, 자발적인 출혈 등 구강편평태선과 관련된 점막 증상이 축적된 치태에 의해 더욱 악화될 수 있다. 따라서 구강편평태선 환자에서 구강편평태선 자체의 약물적 치료뿐만 아니라 적절한 구강 위생 관리, 치석 제거 등의 치주 치료가 동반되어야 한다. 본 증례에서는 구강편평태선 환자에서 국소적인 코르티코스테로이드 치료뿐만 아니라 구강 위생 교육을 포함한 치주 치료를 통해 증상 및 징후를 개선시키고 재발 방지를 도울 수 있었다.

Background: Various oral health management programs in Korea affect the oral health improvement in the elderly Several studies have been conducted to date; however, those studies have not shown uniform results due to the differences in research methods or designs. Hence, this study aimed to review the overall research trends of the reported oral health care programs for the elderly in Korea, verify their effects, and clarify them based on the systematic literature review. Methods: The literature search selected intervention studies that applied the oral health care program for the elderly in Korea from 2001 to 2020. Following the COre, Standard, and Ideal (COSI) models presented by the US National Library of Medicine, we selected databases including Korean studies Information Service System (KISS), ScienceOn, Research Information Sharing Service (RISS), DBpia, PubMed, and Google Scholar. Of the 1,335 studies searched using keywords, titles, and abstracts, 21 were finally selected based on primary and secondary exclusion criteria. Results: The most frequent intervention period was 4 weeks, and the number of interventions varied between 2 and 90 times. As for the type of intervention, 14 studies that conducted both theory and practice were the most frequent. Significant differences in the clinical indicators, such as calculus, halitosis, salivation rate, swallowing function, and dry mouth, were found in most oral health care programs. Conclusion: Based on the results of this study, the intervention program needs further verification using multiple indicators in future studies. In addition, a study extending the intervention period and the number of samples is considered necessary for verifying continuous effectiveness of the intervention program.

Background: Although the orofacial-function improvement exercise (OFIE; oral exercise) was first introduced in Korea 10 years prior, it is still not covered by medical insurance, and no detailed survey on the dissemination of related programs has been conducted. Therefore, this study investigated the actual status of the education and practice of OFIE among the elderly and at elderly welfare institutions in the Seoul and Gyeonggi Provinces. Methods: Senior citizens aged more than 65 years old, public health centers (total of 69) and elderly welfare institutions (including nursing homes and elderly welfare centers, total of 56) per administrative area in the Seoul and Gyeonggi Provinces were targeted. We analyzed 200 elderly people and 93 institutions who agreed to participate in the survey. For the elderly, general characteristics, experience and route, current practice, and necessity regarding OFIE were investigated. For institutions, the history and plan of education programs on OFIE were investigated. Results: Regardless of the general characteristics, both the rate of experience and practice for OFIE were low overall; moreover, although they felt it was necessary, they had insufficient motivation for its implementation. Moreover, only a few institutions which were operating the education about OFIE regardless of the COVID-19 situation. Conclusion: Although OFIE is necessary for the elderly, its distribution remains insufficient. Therefore, further efforts are needed to expand the education and raise the awareness of oral exercise among elderly individuals and senior welfare institutions.

Salicornia herbacea L. (S. herbacea) is an annual herbaceous plant of Chenopodiaceae. It grows in groups on the coast or mud flat of Korea is known to be rich in minerals. S. herbacea has potent anti-cancer, antioxidant, anti-obesity, bowel function improvement. However, pharmacological mechanisms of S. herbacea extract (SHE) remain poorly understood. The aim of this study was to investigate the potential acute toxicity of SHE in ICR mice administered a single oral dose of 0, 500, 1,000, and 2,000 mg/kg by gavage. After administration of the extract, signs of toxicity were observed every day for 14 days. No mortality, abnormal clinical signs, body weight, organ weight or pathological changes were observed compared to a control group, and there were no differences in the body weights of the control and treatment groups. Biological serum activities and histological tests were not significantly changed in the treatment group compared to the control group. Especially, treatment of SHE was significantly decreased of total cholesterol and triglyceride levels. These results indicated that a single oral administration of SHE does not exerts any toxic effects at a dose of 2,000 mg/kg and that the $LD_{50}$ of SHE is greater than 2,000 mg/kg. Accordingly, SHE appears to have potential in various functional agents of foods, without toxicity.

This review evaluates the literature on the relationship between mandibular condylar process fracture and temporomadibular joint (TMJ). The topic of condylar fracture generated more discussion and controversy than any other field of maxillofacial trauma associated with TMJ. Disturbance of occlusal function, devia-tion of mandible, internal derangements of TMJ, and ankylosis of the joint with resultant inability to move the jaw are sequelae of condylar process fracture. Thus it is necessary to understand how the masticatory system adapts to the structural alterations that accompany fractures of the mandibular condyle. Treatment of condylar process fracture include two methods ; closed treatment and open treatment. If one chooses totreat closed, one must understand that adaptations in the musculature, skeleton, and dentition will be necessary. Open treatment of condylar process fractures probably requires fewer adaptations within the masticatory system to provide a favorable functional outcome. However, one must weigh the risk of open surgery against the possible improvement in outcome. The risks are not just surgical risk, but biological risk as well, such as disruption of the blood supply to the condyle. This review presents relevant aspects of change of TMJ associated with condylar process fracture.

Optic nerve injury serious enough to result in blindness had been reported to occur in 3% of facial fractures. When blindness is immediate and complete, the prognosis for even partial recovery is poor. Progressive or incomplete visual loss may be ameliorated either by large dosage of steroid or by emergency optic nerve decompression, depending on the mechanism of injury, the degree of trauma to the optic canal, and the period of time that elapses between injury and medical intervention. We often miss initial assessment of visual function in management of facial fracture patients due to loss of consciousness, periorbital swelling and emergency situations. Delayed treatment of injuried optic nerve cause permanent blindness due to irreversible change of optic nerve. But by treating posttraumatic optic nerve injuries aggressively, usable vision can preserved in a number of patients. The following report concerns three who suffered visual loss due to optic nerve injury with no improvement after steroid therapy and/or optic nerve decompression surgery.

Objectives : This study aims to analyze the tasks, recognition and obstacles in operation of school dental clinics and to examine opinions on installation, operation and prerequisites for toothbrushing facilities. Methods : It conducted a survey t o the persons in charge at 378 school dental clinics in Korea and total 127 sheets, excluding incompletely answered data, were used for analysis by using SPSS 18.0. Results : Two regular dental hygienists visit school dental clinics 2-3 times per week and work 4-6 hours per week on average. Their tasks include oral health education, toothbrushing instruction, oral examination, sending school newsletters, and dental sealants. The obstacles of operation include excessive workload other than the work for the school dental clinic, lack of dentists, and lack of cooperation of principals and teachers in school. The persons in charge think that the chief task of the school dental clinic is the continuous oral health management, and it effectively affects students' oral health improvement. Most of them were for the installation of toothbrushing facilities. They said that it will be effective in students having an adequate toothbrushing habit and their toothbrushing rate increasing higher. They thought that if the school dental clinic is changed to toothbrushing facilities, it will improve students' oral health management. The prerequisites for toothbrushing facilities are the support of manpower in charge, principal's support, and development of operational programs. Conclusions : The most effective function of school dental clinics is constant oral health management. However, when public health doctors are reduced and dental sealants get included in health insurance, the budget of local government will decrease and then it will eventually reduce the work of school dental clinics. Therefore, it is needed to enhance support for school dental clinics or install a toothbrushing facilities rather than a school dental clinic.

Submucosal type cleft palate is a kind of cleft palate. A submucosal cleft may result in shortening of the anteroposterior dimension of the hard or soft palates or both. The increased distance along with the lack of muscle connection in the soft palate usually accounts for the lack of palatopharyngeal function in patients with submucosal cleft. Resonance disorders which is found in cleft patients show hypernasality or hyponasality. Many cases of submucosal type cleft palate patients visit our clinics due to hypernasality. In this study, resonance disorders was evaluated through nasalance test. Experimental group was composed of submucosal type cleft palate patients. The patients were treated by a so-called combined therapy, i.e., operation and speech training. To observe the changing pattern by surgery, nasalance test was carried out one time before surgery and three times after surgery. Nasometer II was used as a examination. The questionaire was filled with single vowels & diphthongs. The mean nasalance score of the child was significantly lower than that of the adult at every vowel. An early age at operation (under 10 years) was that a better functional result was achieved with patients. The mean nasalance score of /i/ was highest and that of /a/ was the lowest. The result of corrective surgery in selected cases has achieved improvement in all cases. Hypernasality has been consistently diminished. he operation.
