측두하악관절장애에 관한 역학연구는 주로 1970년대 초 스칸디나비아국가에서 국민을 대상으로 무작위 추출법에 의한 악관절 및 저작계기능에 관한 역학조사로 시작되었으며 국내에서도 1970년대 이후 측두하악관절장애의 유병률에 대해 많은 역학연구가 보고되었다. 하지만 성, 병력, 주소, 진단에 따른 각각의 증상과 징후들을 평가한 연구는 외국에 비해서 많이 부족한 실정이다. 측두하악관절장애에 대한 증상과 진단에 관한 총괄적 연구조사는 오래전에 이루어진 것이 대부분이기 때문에 본 연구를 통해서 측두하악관절장애를 가진 환자들의 성, 병력, 주소, 진단에 따른 증상들을 총괄적으로 조사하여 향후 점증하는 측두하악관절장애환자의 진단과 치료에 도움이 되는 기초자료를 확보하고자 하였다. 본 연구결과를 보면 우선 연령의 경우 전체 내원 환자 6500명의 평균나이는 34.06세로 남자는 33.15세, 여자는 34.62세였으며 진단그룹별로 연령차이가 있었다. 의뢰 환자는 대체로 치과의사가 의뢰한 환자가 많았으며(80.07%), 의뢰한 환자 진단군은 관절성장애, 근육성장애, 연조직질환 순이었다. 전체 내원 환자 중 63%가 안면통증으로 내원하였으며, 발생부위에 대한 비교에서 좌우 유의한 차이를 볼 수 없었다. 또한 통증 발생은 6개월 미만에서는 주로 남성이, 6개월 이상인 경우는 여성의 비율이 상대적으로 높음을 알 수 있었다. 관절잡음의 경우 병력 환자는 3445명(53.15%)였으며, 발병시기에는 성차가 없었다. 관절잡음의 발생부위는 좌우 양측간에 차이가 없었으며 주로 clicking sound가 많음을 알 수 있었다. 이갈이는 주로 남자에서, 이악물기는 여자에서 나타났었다.

Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups. (p<0.05) 5.The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, forteen (36.9%) were located at the posterior attachment and one (2.6%) was at the meniscus itself.

The purpose of this study was to investigate the magnitude of mandibular rotational torque movements in subjects with TMJ sounds, and to analyse correlation between quantitative characteristics of TMJ sounds and mandibular rotational torque movement. Twenty dental college students with TMJ clicking and twenty students without any TMD signs and symptoms were examined by mean of SonoPak and Rotate program of BioPAK system(Bioresearch Inc. MilWaukee, wisconsin, USA) in this study. Mandibular rotational torque movements were recorded and analysed during maximum mouth opening, protrusion, and lateral excursion in frontal and horizontal planes. The obtained results were as follows: 1. On maximum mouth opening, mandibular rotational angle and distance of clicking group were significantly greater than those of control group in frontal plane. (P<0.05). 2. During maximum mouth opening closing, maximum mandibular rotational angle and distance of clicking group were significantly greater than those of control group in frontal plane. (P<0.01). 3. On protrusion, mandibular rotational angle and distance of clickin group were significantly greater than those of control group in horizontal plane. (P<0.05). 4. On lateral excursion, there was no significant difference in mandibular rotational angle and distance between clicking group and control group in frontal and horizontal planes. 5. There were significant correlations between peak amplitude of TMJ sounds and maximum mandibular rotational distance during maximum mouth opening (r=-.481) and mandibular rotational distance on maximum mouth opening (r=-.455) in horizontal plane. 6. There were significant correlations between Above 300/(0-300)Hz ratio of TMJ sounds and mandibular rotational angle (r=-.499) and distance (r=-.457) on maximum mouth opening in frontal plane.

악관절 동통은 여러 가지 원인에 의해 발생하는 것으로서 동통을 호소하는 환자에서 Bone SPECT의 유용성을 알아보았다. 악관절 동통을 호소하여 Bone SPECT를 시행한 34명을 대상으로 하였으며 모든 환자에서 단순 촬영, planar 골스캔, Bone SPECT를 시행하였다. Bone SPECT에서 동위원소의 섭취 증가 정도에 따라 3가지로 분류하였다. Grade 0은 정상, Grade I은 후두골과 비슷한 섭취 증가, Grade II는 상악동과 비슷한 섭취 증가가 있는 것으로 정하여 각각 섭취 증가 정도에 따라 환자의 임상 증상과 치료 방법을 비교 분석했다. 34예중 27예 (80%)에서 악관절 Bone SPECT 시행시 섭취 증가가 있었고, 이중 21예 (78%)에서 하악과두에 섭취 증가가 있었고 나머지 6예 (22%)에서 하악궁과 상악궁에 섭취가 있었는데 이들은 치주질환으로 확인되었다. 총 34예중 Grade 0인 7예 (20%)에서는 관절 잡음이 3예 있었고 4예에서 약물 치료로 증상이 호전되었고 나머지 3예에서 치료 없이 증상이 호전되었다. Grade I 인 4예(12%)에서는 관절잡음이 3예 있었고 모두 약뭍 치료로 증상이 호전되었다. Grade II 23예(68%)중 관절 잡음은 7예 있었고 14예에서 약물치료 및 관절천자와 같은 감압술을 병행하여 증상이 호전되었다. 6예에서는 치주 치료로 증상이 호전되었다. 총 34예중 평면 골스캔에서는 11예(32%)에서 섭취 증가가 있었다. 단순 촬영에서는 16예(47%)에서 관절내강 협소 혹은 팽대, 골리란, 관절운동 제한 등이 관찰되었다. one SPECT는 악관절 동통 환자에서 유용하게 사용할 수 있는 진단적 방법이며, 치료방법을 결정하는 데 도움이 되었다. 동위원소 섭취 증가가 많을 수록 환자 치료에 보다 적극적인 치료를 필요로 하였으나 임상 증상과 동위원소 섭취증가는 밀접한 관계는 없었다.

Background: The purpose of this study is to introduce our modified disc plication technique using MITEK mini anchors and to evaluate the clinical outcome for patients with internal derangement (ID) of the temporomandibular joint (TMJ). Patients and methods: We evaluated 65 joints in 46 patients, comprised 32 women and 14 men, who first visited the Asan Medical Center from December 2012 to December 2016. The age of the patients ranged from 14 to 79 years, with a mean age of 36.6 years. The patients presented with joint problems including pain, joint noise, and mouth opening limitation (MOL). Patients who met our inclusion criteria underwent unilateral or bilateral disc repositioning surgery with our minimally invasive disc plication technique using MITEK mini anchors and No. 2-0 Ethibond^® braided polyester sutures. The variables taken into account in this study were the range of maximum mouth opening (MMO), painful symptoms (evaluated with the visual analog scale, VAS), and the type of noise (click, popping, crepitus) in the TMJ. Results: Preoperative examination revealed painful symptoms in 50.7% (n = 35) of the operated joints (n = 69) and the presence of clicks in 56.5% (n = 39). Postoperative examination revealed that 4.3% (n = 3) of the operated joints had painful symptoms with lower intensity than that in the preoperative condition. Additionally, 17.4% (n = 12) had residual noise in the TMJ, among which two were clicking and the other 10 had mild crepitus. The intensity of the postoperative residual noise was significantly decreased in all cases compared to that in the preoperative condition. Among patients with MOL below 38 mm (n = 18), the mean MMO was 31.4 mm preoperatively and 44.2 mm at 6 months postoperatively, with a mean increase of 13.8 mm. A barely visible scar at the operation site was noted during the postoperative observation period, with no significant complications such as facial palsy or permanent occlusal disharmony. Conclusion: Subjective symptoms in all patients improved following the surgery. TMJ disc plication using MITEK mini anchors with our minimally invasive approach may be a feasible and effective surgical option for treating TMJ ID patients who are not responsive to conservative treatment.

Registration of the mandibular movement in patients with temporomandibular joint noise (clicking and/or crepitus) was performed using one of mandibular tracking devices(SAPHON VISI-TRAINER CII,Tokyo Shizai-sha Inc.,Japan). The obtained results were follows : 1. In many cases, the movement pattern of light emitting diode(LED) attached on the mandibular midline showed lateral deviation from a vertical reference line which was pronounced in association with TMJ noise during opening and closing. 2. In patients with unilateral TMJ noise the mandibular midline usually towards the side demonstrating TMJ noise during opening. 3. A distinct V-shaped discontinuity in the trace of velocity of mandibular movement was found at the point of the TMJ noise. 4. In patients with TMJ noise the velocity of mandibular movement at the point of the TMJ noise was decreased rapidly. 5. In several cases, TMJ noise could be eliminated by traning of Rocabado`s control of TMJ rotations.

목적: 단순악관절 진동군에서 좌/우 진동 중 유의한 진동의 감별법을 연구하는 것이다. 연구 재료 및 방법: 단순악관절 진동만을 갖고 있고 측두하악관절 질환의 제 증상이 없는 단순악관절 진동그룹 30명의 60개 관절에서 44쌍의 진동을 기록하였고 대상자의 인지와 검사자의 촉진, JVA 검사 결과를 비교하였다. JVA로 기록된 진동의 주파수 스펙트럼, 진동파형 시간차 위상변위 분석, 수치 분석을 통해 좌/우 진동 중 유의한 진동을 감별하였다. 결과: JVA 분석결과 양측성 진동은 한 건도 없었으며 유의한 편측 진동은 42개로 감별되었다. 시간차 위상변위를 보이는 것은 11쌍이었고 이 중 한 쌍을 제외한 모든 진동에서 전달된 측의 진동이 발생측 진동보다 진동 총에너지(total integral) 값은 더 작고 > 300 / < 300 ratio는 같거나 더 큰 특징을 보이는 것을 관찰하였다. 또한 진동 총에너지 값이 10 이하로 작고 시간차 위상변위를 보이지 않아 좌/우 감별의 근거가 모호한 나머지 진동 모두에서 진동 총에너지 값이 더 작은 쪽의 > 300 / < 300 ratio가 더 큼을 관찰하여 이를 좌/우 감별의 근거로 삼을 수 있었다. 결론: JVA로 좌/우 진동 중 유의한 진동을 감별하기 위해서는 주파수 스펙트럼, 시간차 위상변위 및 수치 분석 등이 모두 고려되어야 한다.

The authors analyzed the clinical findings, radiological findings and their correlations in the temporomandibular joint disorders. The results were as follows: 1. The most prevalent age group was in the first decade, then the second decade and the third decade. Female were more common with a ratio of 3.4:1. 2. The most common clinical findings was the pain on open mouth position (42.3%), then came the clicking and limitation of mouth opening. 3. The most common bone change on the condyle side was the erosion, then came the flattening, the osteopyte and the sclerosis in that orders. 4. In the case of the crepitus, the coarse crepitus showed more radiological change than the fine crepitus. The 27% of the patients with crepitus showed the bone change and the patients with crepitus showed more bone change than any other clinical symptoms. 5. In the case of the mouth opening limitation, the evaluation of the translatory movement by transcranial projection was in accordance with the clinical evaluation. 6. The correlation between the clinical symptom and the condylar position within the mandibular fossa was not present and in the case of diagnosis of disc displacement, the transcranial projection seemed not to be able to substitute for the arthrography. Radiographically, the most prevalent age group which showed the bone change was in the first, the second and the third decade. And the bone change seemed to have no relationship with aging.

The author obtained the oblique lateral trans cranial radiograms from 376 patients (114 of male, and 262 of female) with temporomandibular joint arthrosis. After tracing each film, the author analyzed the dimensional changes of the condylar heads with pain, clicking, mouth opening limitation, and masticatory difficulty respectively, which were the chief complaints of the TMJ arthrosis and compared these data with control group. The results were as follows; 1. There was a great predilection for occurrence of the TMJ arthrosis in female (262 cases) over male (114 cases). But there was no significant difference in ratio between the sexes on each symptom. In male, 60 patients (52.6%) had pain, 28 patients (24.6%) had clicking, 21 patients (18.4%) had mouth opening limitation, and 5 patients (4.4%) had masticatory difficulty. In female, 148 parients (56.5%) had pain, 57 patients (21.8%) had clicking, 47 patients (17.9%) had mouth opening limitation, and 10 patients (3.8%) had masticatory difficulty. 2. Examined controlled group, the author analyzed the dimension of W-W', 0-H, 0-A, 0-B on the right side first, and left side second. In male, the dimension of W-W' was 14.52㎜, 14.13㎜; 0-H was 13.92㎜, 13. 71㎜' 0-A was 8.91㎜, 9.0㎜ and 0-B was 8.67㎜, 8.78㎜.

Male with mouth opening limitation show the least (12.70㎜, 13.00㎜) on W-W', but both sexes with pain show the least on 0-H. There was no significant difference between experimental group with Clicking and controlled group on 0-H, 0-A, and 0-B. And also there was no difference on 0-B in patients with every symptom except masticatory difficulty. The dimensional changes of the condylar heads with those symptoms were as follows; a) In male patients, complaing of pain, W-W' of the right and left was 13.80㎜, 12.80㎜; 0-H was 13.10㎜, 12.90㎜; 0-A was 8.69㎜, 8.18㎜; 0-B was 8.33㎜, 8.42㎜. In female, W-W' was 13.01㎜, 12.90㎜; 0-H was 12.48㎜, 12.80㎜; 0-A was 8.60㎜, 8.49㎜; 0-B was 8.48㎜, 8.50㎜. b) In male patients with clicking, W-W' was 13.70㎜, 13.10㎜; 0-H was 13.90㎜, 13.10㎜; 0-A was 8.81㎜, 8.16㎜ 0-B was 8.34㎜, 8.25㎜. In female, W-W' was 13.10㎜, 13.50㎜; 0-H was 13.30㎜, 12.91㎜; 0-A was 8.95㎜, 8.49㎜; 0-B was 8.23㎜, 8.70㎜. c) In male patients with mouth opening limitation, W-W' was 12.70㎜, 13.00㎜; 0-H was 13.40㎜, 13.40㎜; 0-A was 8.37㎜, 8.48㎜; 0-B was 8.33㎜, 8.62㎜. In female, W-W' was 13.00㎜, 12.50㎜ 0-H was 12.90㎜, 13.10㎜; 0-A was 8.49㎜, 8.09㎜; 0-B was 8.77㎜, 8.01㎜. d) In male patients with masticatory difficulty, W-W' was 13.30㎜, 13.20㎜; 0-H was 13.40㎜, 12.60㎜; 0-A was 8.26㎜, 8.32㎜; 0-B was 7.80㎜, 8.20㎜.

The authors analyzed the morphological change of bone structure from 3,140 radiographs (1570 joints) of 785 patients with temporomandibular joint arthrosis, which were obtained by the oblique lateral transcranial projection and orthopantomographs. The interrelation of bone change and clinical symptoms, duration of the diseases were examined. Also, the bone changes of articular eminence, condyle, articular fossa were examined according to positional change of the condyle in the mouth open and close state. The results were as follows. 1. In the 785 patients with TMJ arthrosis, 782 patients (99.62%) show the positional change of the condyle. Among them 691 patients (88.03%) show the bone change. 2. In TMJ arthrosis patients with bone changes 451 patients (65.27%) showed both the condylar positional changes and bone changes bilaterally. 198 patients (28.65%) show the condylar positional changes bilaterally and bone changes unilaterally. 3. The bone changes in the TMJ arthrosis were in order of frequency eburnation (647 cases, 32.8%), erosion (548 cases, 27.79%), flattening (418 cases, 21.20%), deformity (138 cases, 6.99%). sclerosis (115 cases, 5.83%), marginal proliferation (106 cases, 5.38%). The region of bone change in TMJ arthrosis with condylar positional changes were in order of frequency the articular eminence (43.97%) condylar head (38.64%), articular fossa (17.39%). In the patients with bone changes, their clinical symptoms were pain (44.34%), clicking sound (33.5%), limitation of mouth opening (22.52%). In the patients complaining pain the most frequent bone change was erosion (28.60%), in the patients complaining clicking sound, eburnation (28.97%) in the patients complaining the limitation, eburnation (29.40%). Also in the patients with the duration below 1 year most common bone change was eburnation. 5. The most common condylar positional change was downward position (39.94%) in closed state, restricted movement of condyle (30.07%) in open state. The condylar positional changes and bone changes according to the region were as follows: a) In the condylar head the most frequent bone change was erosion (30.45%) and the most frequent condylar positional change was downward position (37.40%) in closed state, restricted movement of condyle (33.2%) in open state. b) In the articular eminence the most frequent bone change was eburnation (39.91%) and the most frequent condylar positional change was downward position (39.79%) in closed state, restricted movement of condyle (27.22%) in open state. c) In the articular fossa the most frequent bone change was eburnation (53.94%) and the most frequent condylar positional change was downward position (42.57%) in closed state, restricted movement of condyle (30.32%) in open state.
