        골격성 제3급 부정교합자의 양악 수술 후 상기도 공간의 변화에 관한 두부 계측 방사선학적 연구

        Purpose: The aim of this study is the changes of upper respiratory airway space in patients with mandibular prognathism after 2-jaw orthognathic surgery in patients with skeletal classs III malocclusion. Method: We measured the lines between selected upper airway landmarks on lateral cephalometric x-ray films of skeletal class III 64 persons who had not been operated yet, were 6 months after operation. The test subjects were divided into 3 groups according to maxillary movement, as follows; maxillary advancement (MA) group, maxillary posterior impaction (MPI) group, maxillary posterior impaction and superior repositioning (MPI+MSR) group. Result: In this study, nasopharyngeal airway space in MPI+MSR group was significantly increased after operation (p<0.05). Oropharygeal and hypopharyngeal airway space in MA group and MPI group were significantly decreased after operation (p<0.05). From hyoid bone to anterior mandible point distance in MA group and MPI group were significantly decreased after operation (p<0.05). Conclusion: Oropharygeal and hypopharyngeal airway space were influenced more by mandibular set-back than maxillary movement. Maxillary movement surgery as well as mandibular setback surgery should be taken into consideration in order to minimize symptoms related to obstructive sleep apnea syndrome after operation.

        골격성 제3급 부정교합자의 양악 수술 후 중안면부 연조직 변화에 관한 두부 계측 방사선학적 연구

        Considering the skeletal class III malocclusion that complains of mandibular prognathism, there have been some studies of the mandibular change for comparing the changes of pre operative with post operative state. Nowadays it is common to do the orthognathic 2-jaw surgery for the correction of the maxillary deficiency, the post operative stability and the esthetics. We compare and analyze the changes of soft tissue around the nose and the lip with the changes in the direction and the amount of maxilla. Patients who were diagnosed as maxillofacial deformity and received orthognathic surgery of both jaws at Yongdong Severance hospital from 2001 through 2003 were included in this study. Their lateral cephalograms were analyzed, and the post operative change of hard tissue and soft tissue were studied. Upon analyzing the preoperative cephalograms and 6 month post operative cephalograms, there were significant in the vertical change of Labialis superius(Ls) and Stomion(Stm) in soft tissue in relation to the vertical change of skeletal landmarks (Anterior Nasal Spine, Subspinale, Prosthion, Incision Superious). In addition, there were no significance in horizontal movement of the skeletal landmarks among groups. In terms of hard tissue landmarks, group 3(maxillary posterior impaction and advancement surgery group) showed significantly greater change in the vertical movement of Anterior Nasal Spine(ANS), Subspinale(A), Prosthion(Pr), and Incision Superious(Is) compared with other groups. In terms of soft tissue change, group 3 showed more significant change in the vertical movement of Ls and Stm. This study calculated the changes of the skeletal and soft tissue landmarks in order to act as a guide in planning and performing the surgery and as a reference in predicting the postoperative change of facial appearance.

        하악 과두부에 발생한 골연골종의 치험례

        김민철,민성윤,주범기,허종기,김형곤,박광호,Kim, Min-Chul,Min, Sung-Yoon,Joo, Bum-Ki,Huh, Jong-Ki,Kim, Hyung-Gon,Park, Kwang-Ho 대한악안면성형재건외과학회 2005 Maxillofacial Plastic Reconstructive Surgery Vol.27 No.3

        Osteochondroma is one of the most common benign tumors of the axial skeleton, but is rarely found in the facial bones. Osteochondroma shows an irregular radiopaque lesion and chondromatic area surrounded by osteoma. It may appear different findings as calcification levels. When it develops in the long bone, it has a marked tendency in the ages from 10 to 20 years and ceases with the end of pubertal growth. However, when it develops in the condyle, it is prevalent in the third decades (average 39.2 years) and continues to develop. Lesions developed in the long bone have a predilection for men (M:F = 2:1), but for women in the mandible. Osteochondroma is differentiated from chondroma, osteochondromatosis and osteoma. Mandibular condyle osteochondroma presents asymptomatic facial swelling, rarely posterior openbite, pain during mouth opening and internal derangement of the temporomandibular joint disc due to condylar lengthening and condylar hyperplasia. The first choice of treatment of the massive osteochondroma is the surgical removal. We report osteochondroma of the mandibular condyle showing good result to treat the lesion.
