The purpose of the current report is to present 6-year long-term stability and 10-year follow-up data for an adult patient who was treated with a tongue elevator for relapsed anterior open-bite. The 19-year-old male patient presented with the chief complaint of difficulty in chewing his food. Collectively, clinical and radiographic examinations revealed an anterior open-bite, low tongue posture, and tongue-tie. The patient opted for orthodontic treatment alone, without any surgical procedure. A lingual frenectomy was recommended to avoid the risk of relapse, but the patient declined because he was not experiencing tongue discomfort. Initial treatment of the anterior open-bite with molar intrusion and tongue exercises was successful, but relapse occurred during the retention period. A tongue elevator was used for retreatment, because the approach was minimally invasive and suited the patient's requirements regarding discomfort, cost, and time. The appliance changed the tongue posture and generated an altered tongue force, which ultimately resulted in intrusive dentoalveolar effects, and a subsequent counterclockwise rotation of the mandible. The results showed long-term stability and were maintained for six years through continual use of the tongue elevator. The results of this case indicated that a tongue elevator could be used not only as an alternative treatment for open-bite, but also as an active retainer.

Cerebral palsy(CP) is one of the most common motor disease, due to brain injury during fetal and neonatal development which results in neuromotor paralysis and associated neuromuscular symptoms. Features of CP include motor disability due to the lack of muscle control, often accompanied by sensory disorders, mental retardation, speech disorders, hearing loss, epilepsy, behavior disorders, etc. There are increasing chances of treatment of dental patients with cerebral palsy, as the occurrence of CP is increasing with the decrease in infant mortality and an increase in immature birth and premature birth and also, there is a trend to pursue of higher quality of life. Reports on the relationship between CP and maxillofacial deformity are uncommon, but it is well known that the unbalance and discontrol of the facial muscles, lip, tongue and the jaws leads to malocclusion and temporomandibular joint disorders, and statistics show that class 2 relationship of the jaws and open bite is frequently reported. However, it is difficult to perform maxillofacial deformity treatment, which consists of orthodontic treatment, maxillofacial surgery and muscle adaptation training, due to difficulties in communication and problems of muscle adaptation caused by difficulties in motor control which leads to a high recurrence rate. This case report is to trearment of maxillofacial deformity in CP patient. A 26 year old female patient came to the department with the chief complaint of prognathism of the mandible and facial asymmetry. According to the past medical history, she was diagnosed as cerebral palsy 1 week after birth, classified as GMFC, classII accompanied with left side torticollis. The patient's intelligence was moderate, and there were no serious problems in communication. For two years time, the patient underwent lingual frenectomy, pre-operation orthodontic treatment and then bimaxillary orthognathic surgery to treat mandibular prognathism and facial asymmetry followed by rehabilitatory exercise of facial muscle. After 6 months of follow up, there was a good result. This is to report to the typical signs and symptoms of DFD in CP patient and the limitation of the usual method of the treatment of DFD in CP patient with literature review.

수면호흡장애(sleep disordered breathing, SDB)는 상기도의 완전한 또는 부분적 폐쇄로 인해 수면 중 반복적인 저호흡과 무호흡이 나타나는 것을 특징으로 하는 질환이다. 소아 SDB 유병률은 대략 12 - 15%이며, 호발 연령은 주로 3 - 5세의 미취학 어린이이다. 어린이는 코골이와 잦은 각성부터 야뇨증, 과잉행동에 이르기까지 다양한 증상을 보인다. 어린이에서 SDB의 주원인은 편도 및 아데노이드 비대로 인한 상기도의 폐쇄이다. SDB를 치료하지 않으면 학습 장애, 인지 장애, 행동 문제, 심혈관 질환, 대사 증후군, 저성장 등과 같은 합병증을 초래할 수 있다. 소아치과 의사는 SDB의 위험이 있는 소아를 감별하는 특별한 위치에 있다. 소아치과 의사는 SDB와 관련 있는 임상 양상을 인지하고, 소아 수면설문지, 측 모두부계측 방사선사진, 휴대용 간이수면검사 등을 이용하여 SDB를 선별하여 전문가에게 의뢰할 수 있어야 한다. 소아치과에서는 치료를 위해 상악궁 확장, 하악 전방 유도장치, 설소대 절제술 등을 시행할 수 있다. 소아치과 의사는 장기간의 구호흡과 저위설, 설소대단축증 등이 비정상적인 안면골격 성장 및 수면 문제를 일으킬 수 있음을 인지하고, 이러한 문제점들을 예방할 수 있도록 조기에 개입할 수 있어야 할 것이다.
