In the treatment of mandibular condylar fractures, arthrocentesis, lavage and selective intermaxillary fixation were performed after closed reduction. In this lavage group, the physiotherapy performed for 3-6 months after injury. in control group, continuous intermaxillary fixation was done for 1-3 weeks, and physiotherapy followed in the same method of the lavage group. In the comparative study of the both groups, the following results are shown. 1. Compared to control group, the lavage group had a slightly superior result at range of motion, joint pain and occlusal deviation, from I day after arthrocentesis to 6 months after injury. 2. The significant differences between both groups were seen at range of motion and joint pain in 1 month after injury. 3. At 6 months after injury, the differences between both groups were not significant at range of motion, joint pain and occlusal deviation. From this study, in the mandibular condylar fracture, the arthrosentesis, lavage and selective intermaxillary fixation after closed reduction can improve symptoms such as joint pain and occlusal deviation, also increase range of motion. in this therapeutic way, intracapsular hemarthrosis which can cause TMJ ankylosis or dysfunction can be removed effectively. in addition, patient's discomfort such as swallowing disturbance, speech disturbance and emotional stress can be reduced signuficantly.

Purpose : The purpose of this study was to find the predictors for successful arthrocentesis for anterior disc displacement without reduction(ADD without Reduction) of the temporomandibular joint (TMJ). Patients and Methods : Arthrocentesis and lavage was carried out in 25TMJs of 22patients whose MRI findings were all anterior disc displacement without reduction. The effectiveness of the treatment was evaluated in terms of the postoperative range of maximal mouth opening (MMO) and the degree of postoperative pain score. Predectors which was analyzed were age, duration of painful locking, MMO, the degree of pain, perioperative clicking and the amounts of irrigation fluid. Results: 18cases (72%) was included to criteria for success. There were no significant differences in age, duration of locking, MMO and the degree of pain statistically. But In 15cases(83%) of successful cases, amouts of irrigated solution recovered to normal MMO were less than 150ml. And In 8cases (44%) of successful cases, perioperative clicking was appeared. Conclusion : Amounts of irrigated solution recovered to normal MMO and the appeareance of perioperative clkicking may be predictors of the successful results of arthrocenetesis of ADD without reduction of TMJ.

Objectives: Joint injuries frequently lead to progressive joint degeneration that causes articular disc derangement, joint inflammation, and osteoarthritis. Such arthropathies that arise after trauma are defined as post-traumatic arthritis (PTA). Although PTA is well recognized in knee and elbow joints, PTA in the temporomandibular joint (TMJ) has not been clearly defined. Interestingly, patients experiencing head and neck trauma without direct jaw fracture have displayed TMJ disease symptoms; however, definitive diagnosis and treatment options are not available. This study will analyze clinical aspects of PTA in TMJ and their treatment outcomes after joint arthrocentesis and lavage. Materials and Methods: Twenty patients with history of trauma to the head and neck especially without jaw fracture were retrospectively studied. Those patients developed TMJ disease symptoms and were diagnosed by computed tomography or magnetic resonance imaging. To decrease TMJ discomfort, arthrocentesis and lavage with or without conservative therapy were applied, and efficacy was evaluated by amount of mouth opening and pain scale. Statistical differences between pre- and post-treatment values were evaluated by Wilcoxon signed-rank test. Results: Patient age varied widely between 20 and 80 years, and causes of trauma were diverse. Duration of disease onset was measured as 508 post-trauma days, and 85% of the patients sought clinic visit within 2 years after trauma. In addition, 85% of the patients showed TMJ disc derangement without reduction, and osteoarthritis was accompanied at the traumatized side or at both sides in 40% of the patients. After arthrocentesis or lavage, maximal mouth opening was significantly increased (28-44 mm on average, P<0.001) and pain scale was dramatically decreased (7.8-3.5 of 10, P<0.001); however, concomitant conservative therapy showed no difference in treatment outcome. Conclusion: The results of this study clarify the disease identity of PTA in TMJ and suggest early diagnosis and treatment options to manage PTA in TMJ.

Purpose : To evaluate the efficacy of arthrocentesis for treatment of closed lock. Material : 42 patients were diagnosed to closed lock by physical, radiographic examriation and undergone arthrocentesis. All patients have a pain and mouth opening limitation on affected site. Method : Arthrocentesis was done under conscious sedation and local infiltration anesthesia, normal saline and some steroid was injected on upper compartment of tempormandibular joint. After pumping and lavage, manual reduction procedure of anterially displaced disc was done. All the patients wear an anterior repositioning splint just after arthrocentesis. The result of arthrocentesis was assessed by pain and difference of mouth opening. Result : Difference of mouth opening after arthrocentesis was improved to 18.85mm and pain was gradually decreased. All patients were worn stabilization type splint after mean 1.84 months. 6 patients had relapse of mouth opening limitation so done arthrocentesis again and delivered good results.

Skull-base osteomyelitis is a rare disease affecting the medulla of the temporal, sphenoid, and occipital bones. In general, it occurs due to external ear canal infections caused by malignant external otitis. Skull-base osteomyelitis usually affects elderly diabetic patients. The patient, a 58-year-old man, was referred for evaluation and management of the left jaw. Clinical examination of the patient revealed pain in the left jaw and mouth-opening deflection to the left. The maximum active mouth opening was measured to about 27 mm. Panoramic, CT, and CBCT revealed bone resorption patterns in the left condyle. Through control of diabetes, continued pharmacological treatment, arthrocentesis, and occlusal stabilization appliance therapy were carried out. The extent of active mouth opening was increased to 45 mm, and pain in the left jaw joint was alleviated. This was a case wherein complications caused by failure to control diabetes induced skull-base osteomyelitis. There is a need for continued discussion about the advantages and disadvantages of arthrocentesis with lavage for patients with skull-base osteomyelitis and other treatment options.

Temporomandibular disorder(TMD) is described as a cluster of disorders characterized by pain in the preauricular area and/or the muscles of mastication; limitations or deviations in mandibular range of motion; and noises in the TMJ during mandibular function. The most common symptom in TMD patients is pain that is aggravated by chewing or other jaw function. These symptoms are appeared when the stimuli loaded in TMJ are over the physiologic tolerance. The primary goal in treatment of TMD is to alleviate pain and lor mandibular dysfunction. TMD treatment can be divided into 2 categories: reversible and irreversible methods. Reversible methods include medication, thermal therapy, habit modification, physical therapy, appliance therpy and arthrocentesis and lavage and irreversible methods include arthroscopic lysis, surgery, occlusal adjustment et al. It is widely accepted that reversible methods are ther first choice of treatments. However if reversible ones are not effective, irreversible methods are considered.

Objectives: This study aimed to evaluate the effect of clinical factors on the outcome of arthrocentesis in the treatment of temporomandibular joint (TMJ) internal derangement. Materials and Methods: Fifty patients with TMJ internal derangement underwent arthrocentesis using ringer's lactate. The present study evaluated the contribution of the clinical variables of age, time since onset, visual analogue scale (VAS) pain level, and range of motion (ROM) on the outcomes of TMJ arthrocentesis: age (${\leq}25\;years$, >25 and ${\leq}40\;years$, >40 and ${\leq}60\;years$), VAS pain level (${\leq}5$, >5 and ${\leq}7$, >7 and ${\leq}10$), and ROM (<25 and ${\geq}25mm$). Odds ratios (ORs) were used to describe the proportional benefit of each variable the on successful outcome of arthrocentesis. For the OR to be clinically relevant or even clinically noticeable, we assumed that the OR would need to be larger than 2. Results: Mean preoperative pain score was $6.49{\pm}1.560$ and at 6 months postoperative was $0.46{\pm}1.147$ with an average decrease of pain score 6 (P<0.001). The mean preoperactive maximum mouth opening was $26.14{\pm}4.969mm$ and mean maximum mouth opening at 6-month inerval was $38.92{\pm}3.392mm$. The mean increase in the mouth opening was a mean difference of 12.78 mm (P<0.001). Logistic regression showed that the maximum benefit occurred in patients aged <25 years (OR, 12.01; P=0.012), a VAS pain level of >7 (OR, 11.25; P=0.039), and a maximum vertical opening of <25 mm (OR, 7.70; P=0.038). Conclusion: Lavage of the superior joint space with ringer's lactate resulted in significant reduction in pain and improvement in mouth opening. Patients with a greater inflammatory component and younger patients benefitted more from arthrocentesis. Evaluation of these clinical variables helped in predictive modelling, which may provide clinicians with the opportunity to identify "at-benefit" patients early and initiate specific treatment.

The purpose of this study is that evaluate the distribution and biological roles of TNF-a, interleukin-1${\beta}$(IL-1${\beta}$), interleukin-6(IL-6) and tissue inhibitors of metalloproteinase-1(TIMP-1) in the synovial fliud of patients with non-inflammatory chronic temporomandibular joint(TMJ) disorders in relation to pain during joint movements and magnetic resonance imaging(MRI) findings. TMJ synovial fluids aspirates were obtained from 36 patients (36 joints) with chronic TMJ disorders and from 8 controls(8 joints). Patients were divided to four groups. The control group was from healthy volunteers(8 joints), group I(18 joints) was patients with anterior disc displacement with reduction, group II(5 joints) was patients with disc displacement without reduction and group III (5 joints) was osteoarthritis. The TNF-${\alpha}$, IL-1${\beta}$ and IL-6 levels in the aspirates were determined by using an enzyme-linked immunosorbent assay and the TIMP-1 level was measured by an enzyme immunoassay. Following examinations for pain during joint movements and MRI observations, these cytokines' level and frequencies of detection were compared. The level of IL-1${\beta}$was not significant different in all groups. but the level of TNF-${\alpha}$, IL-6 and TIMP-1 were significant different among groups. The level of IL-6 and TIMP-1 were correlated to pain during movement(p<0.01) and the level of TNF-a(p<0.05). Also, the level of IL-6 was correlated to the level of TIMP-1(p<0.01). Especially, The level of the TIMP-1 level was significantly correlated to the pain during movement and showed very high levle of Pearson's correlation coefficient (r=0.833)(p<0.001). The results indicated that the TNF-${\alpha}$, IL-6 and TIMP-1 levels in the TMJ aspirates of patients with chronic TMJ disorders have been raised. Especially, IL-6 and TIMP-1 were very high levels in the patients who were degraded in the TMJ. Also, TNF-${\alpha}$, IL-6 and TIMP-1 showed the significant correlation in the chronic temporomandibular joint disorders. Therefore I suggest that these cytokines were also correlated to the pain during movement in the chronic temporomandibular joint disorders.

Purpose : This study was to evaluate the effectiveness of arthroscopic management for septic elbows. Materials and Methods : The subjects were 7 patients ranged in age from 6 to 32 years. All patients were diagnosed as having septic arthritis of the elbow after arthrocentesis. Emergency arthroscopic lavage, debridement, and selective synovectomy for infective and necrotic tissue were performed. All patients had a follow-up period of more than 12 months by checking leukocyte count, ESR, CRP and range of motion. Results : For children, we found a return to normal of laboratory tests for infection after an average of 8.4 days while for adults, it required 12.3 days. After 12 months all patients showed normal elbow function as well as normal blood tests. Conclusion : We found arthroscopic management for septic arthritis of the elbows made it possible to visualize the pathologic findings directly and protect further articular damage. In conclusion, arthroscopic management is one of the efficient methods for controlling the joint infection.
