  • 소아들에게서 커다란 치성낭은 주위 해부학적 구조물뿐만 아니라 발육 중인 영구치의 변위를 일으키게 되는데 이러한 경우 적출술이나 조대술이 치료법으로 사용되어 진다. 이 증례는 상악에서 발생한 커다란 낭종으로 인해 3개 이상의 영구치와 더불어 상악동 기저부의 거상이 함께 발생한 5세 남자 환자, 10세 남자 환자 2가지 증례를 보고하고 있다. 두 증례 모두에서 합병증을 최소화하기 위해 조대술이 선택되었으며 조대술 후 맹출 유도를 위한 맞춤 제작 아크릴 폐쇄 장치(obturator), 개창술(window opening), 교정적 견인을 점진적으로 시행하여 양호한 예후를 보였기에 이를 보고하는 바이다.

  • Background: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. Methods: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. Results: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. Conclusions: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.

  • Fractures of the styloid process of the temporal bone may occur with or without an obvious relation to trauma. The incidence of either isolated styloid process fracture or in combination with mandibular fractures is rare, and such occurrences are often misdiagnosed or neglected. A fractured styloid when displaced may impinge on adjacent vital structures, leading to neurological or vascular symptoms that vary according to the anatomical structure compressed. Styloid process fractures associated with atlas/C1 fractures have also been rarely reported in the literature. In this review of literature, the majority of patients was treated conservatively, as few demonstrated the necessity of surgical intervention. There is a definitive need for a protocol to recognize and classify styloid fractures to plan for further treatment. The aim of this review was to achieve a comprehensive understanding of all types of styloid fractures, determine the clinical severity of symptoms, and to consider management and prognosis. In addition, a new classification of cervico-stylo-mandibular fractures is proposed based on important evidence in the literature regarding clinical and radiographic factors that might influence the treatment and prognosis of such fractures.
