MKG를 이용한 하악 과두골절 환자 하악운동에 관한 연구
오향락,진우정,신효근 全北大學校 齒醫學硏究所 1992 전북치대논문집 Vol.10 No.1
In order to obtaining the data on functional mandibular movement of condylar fracture patients, the author investigated 22 condylar fracture patients who visited Chonbuk National University Hospital and 23 dental students of Chonbuk National University Hospital who were diagnosed to be normal by Helkimo's clinical dysfunctional index. All patients and control group were measured on mandibular opening and closing, resting position, swallowing masticatory movements by the use of MKG K6 diagnostic system. The results were as follows : 1. The amount of total and vertical opening movements of fractured groups was lesser than that of control group(P<0.05) such as 36.02㎜, 25.27㎜ of closed & 37.29㎜, 25.69㎜ of open reduction and 43.82㎜, 31.76㎜ of control groups especially that of vertical opening movement was lesser(P<0.01), but there was no difference between the closed & open reduction groups. 2. In the habitual movement & maximum movement, the maximum and average closing velocities were lesser than that of control group(P<0.01), but there was no difference between the closed & open reduction groups. 3. All mandibular movements of patient group were lesser than that of control group, except the vertical movement of resting position such as 1.5㎜ of closed, 1.47㎜ open reduction groups. 4. There was no difference between functional movements of closed, open reduction & control groups such as resting position, swallowing, mastication.

This is a comparative study of functional mandibular movements between the condyle fracture patients and control group who diagnosed to be normal by Helkimo s clinical dysfunction index. In order to obtaining the datas on functional mandibular movement of condylar fracture patients, the auther investigated 22 condylar fracture patients who visited Chonbuk National University Hospital. All patients and control group were measured on mandibular openign & closing movement, resting position, swallowing, masticatory movements, using of MKG(mandibulokinesiograph) K6 diagnostic system. The obtained results were as follows: 1. The amounts of total and verical mouth opening movements of fracture group was lesser than that of control group(p<0.05) such as 36.01mm, 25.27mm of closed reduction. 27.29mm, 25.69mm of open reduction and 42.82mm, 31.76mm of control groups, especially that of vertical opening movement was lesser(p<0.01), but there was no difference between closed & open reduction groups. 2. In the habitual and maximum opening & closing movement, the maximum and average closing velocity were lesse than that of cntrol group(p<0.01), but there was no difference between the closee & open reduction groups. 3. All mandibular movements of patient group were lesser than that of control group, except the vertical amounts of resting position such as 1.5mm of closed, 1.47mm of open reduction groups. 4. There was no difference between functional movements of patients and control group such as resting position, swallowing, mastication

Orbital blowout fractures most often occur following blunt trauma to the periobital region. Medial orbital wall fracture first occur at the weakest point of the orbital wall, lamina papyracea of the ethmoid. Medial orbital wall fractures are isolated or combined type with nasal bone, orbital floor, zygoma, ethmoid and frontal bones. Clinical features of the medial orbital wall fractures include periobital edema and ecchymosis, subcutaneous emphysema, epistaxis, limitation of ocular motion, diplopia, and enophthalmos. Goals of treatment in medial orbital wall fracture are reduction of herniated orbital soft tissues and complete reconstruction of orbital wall. We have experienced patients with isolated medial orbital wall fracture and reconstructed medial orbital walls with Medpor and obtained good results.

하악 전돌증 환자에서 악교정 수술전후의 하악 과두각의 변화에 관한 연구
백진아,오향락,신효근 全北大學校 齒醫學硏究所 1993 전북치대논문집 Vol.11 No.1
The main purpose of the surgical correction of dentofacial deformity is to improve esthetic appearance and masticatory functions. In this study, changes in intercondylar width (ICW) and condylar angulation that occurred following bilateral sagittal split osteotomy and mandibular setback were documented and examined using submentovertex radiography. Also, ICW and condylar angulation of patients group were compared with normal control group. Twenty normal adults and sixteen patients were involved in this study. The results were obtained as follows ; 1. Mean condylar angulation of normal control group (n=20) with normal TMJ function and normal occlusion were 15.96° on Left TMJ and 18.30° on Right TMJ. 2. Mean preoperative condylar angulation of patient group were 17.28° on Lt. TMJ and 18.97° on Rt. TMJ. There was no significant difference between the preoperative condylar angulation (n=16) and normal control group (n=20). 3. Mean postoperative condylar angulation of patient group were 17.88° on Lt. TMJ and 18.97° on Rt. TMJ. There was no significant difference between the pre-and postoperative condylar angulation(P>0.05). 4. Mean ICW of normal control group(n=20) was 107.35㎜ and mean ICW of patient group was 104.28㎜. There was no significant difference between preperative ICW and normal control group. 5. Mean postoperative ICW of patient group was 108.13㎜. There was no significant difference between the pre-and postoperative ICW.(P>0.05) 6. There were no significant differences between pre-and postoperative ICW and condylar angulation of male patients (n=6) and female patients (n=10) groups.

시상면 병행에 근거한 신개념의 하악상행지 시상분할 골절단술
백진아,이국엽,오향락,고승오,진우정 大韓顎顔面成形再建外科學會 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.6
Sagittal split osteotomy (SSRO) is an indispensable and most popular operation for correction of mandibular deformity. The procedure was considered of bony contact surface and nerve injury in the early stage. The procedure has undergone continuous surgical modifications for condylar displacement, relapse, psychologic analysis, functional & esthetic improvement, fixation method and postoperative evaluation of soft tissue change over time. In this article, we compared the contemporary operation method with new method which was designed through ramal computed tomography. Now we are going to introduce novel conceptual SSRO namely CNU-SSRO designed by Chonbuk National University and suggest the standardization of pre-existed SSRO.
