RESUMO

Aim: Temporomandibular disorders (TMDs) are clinical situations that are characterized by pain, sound, and irregular movements of the temporomandibular joints. The most common method in the treatment of TMDs is arthrocentesis. This study aims to compare the effect of conventional extraoral auriculotemporal nerve block (ANB) and Gow-Gates (GG) mandibular anesthesia techniques on patient comfort in an arthrocentesis procedure. Materials and Methods: We performed this study on 40 patients who underwent TMJ arthrocentesis with ANB (n = 20) or GG (n = 20) mandibular anesthesia techniques at the Marmara University Faculty of Dentistry between 2016 and 2019. The predictor variable was the type of an anesthesia technique, and the outcome variables included were pain, maximum mouth opening (MMO), and protrusive movement (PM). They were compared at the preoperative period and 3rd and 6th month periods. Statistical analysis included means with standard deviations, a one-way ANOVA for continuous data, and the results were evaluated at the significance level of p < 0.05. Results: No statistically significant difference was observed between the VAS values, MMO, and PM averages of preoperative, 3rd and 6th months of ANB and GG (p=0.142, p=0.209, and p=0.148). Conclusion: Both anesthesia techniques have provided effective results in terms of pain and functional jaw movements in the postoperative period in arthrocentesis treatment.

RESUMO

This study aimed to investigate the effects of arthrocentesis with intra-articular hyaluronic acid (HA) injection on mandibular condyles using fractal dimension (FD) analysis. Patients with temporomandibular joint (TMJ) internal derangement (ID) were divided into three groups according to how many times the arthrocentesis with HA injection was performed. FD analysis is a quantitative concept that provides information about trabecular bone microstructures. Regions of interest were selected from bone areas close to the articular surfaces of the right and left condyles on panoramic radiographs, which were taken before the procedure (T0) and at the sixth month (T1) after the procedure. Then, the FD values were calculated. All images were reviewed by the same researcher. A two-way repeated-measures analysis of variance was used to determine whether there was a significant interaction between groups, treatment sides, and time on the FD values. A total of 140 patients, including 118 patients who received bilateral arthrocentesis with HA injection and 22 control patients, were included in the study. The images of 20 randomly selected patients were re-evaluated after 2 weeks. As a result of the correlation analysis, there was no significant difference between the two measurements (P > 0.05). The main effect of time on the FD value was significant [F (1, 136) = 157.879, P < 0.001]. This effect was qualified by a significant time × group interaction effect [F (3, 136) = 18.533, P < 0.001]. The increases in the mean FD values on the right and left sides in all treatment groups between T0 and T1 times were significant (P < 0.001 for all), whereas changes in FD values on the right and left sides between T0 and T1 times were not significant in the control group (P = 0.164 and P = 0.557, respectively). After arthrocentesis with HA injections, the mean FD values increased in the mandibular condyles, depending on time in all treatment groups. Patients with TMJ ID are likely to have radiologically detectable degenerative changes and abnormalities in the condyles. The FD analysis method, which provides quantitative data, is recommended as an adjunct and guide for oral and maxillofacial surgeons in radiological examinations that should be performed together with clinical examination for the follow-up of microstructural changes in the condyle after arthrocentesis with HA injection.

RESUMO

AIMS: To compare the clinical effectiveness of conventional double-puncture vs single-puncture type 2 arthrocentesis for management of temporomandibular joint (TMJ) disc displacement without reduction (DDWOR) after 3 years of follow-up. METHODS: A total of 26 patients with DDWOR were randomly and blindly allocated into two treatment groups (n = 13 each): group 1 = conventional double-puncture arthrocentesis; group 2 = single-puncture type 2 arthrocentesis. Data on gender, side of painful joint complaint, age (years), duration of joint pain (months), maximum interincisal distance (MID, mm), and pain intensity (self-reported with a 0-10 visual analog scale [VAS]) were collected. VAS scores and MID were measured before (baseline) and 3 years after (final) the arthrocentesis. RESULTS: Twenty-three patients completed the study (group 1, n = 11; group 2, n = 12). Both techniques resulted in significantly reduced VAS scores and increased MID (P = .001) after the 3 years of follow-up; however, there were no statistically significant differences between techniques (P > 0.05). CONCLUSION: The two arthrocentesis methods tested were both effective in reducing VAS scores and increasing MID in patients with DDWOR.

RESUMO

INTRODUCTION: Although Kocher criteria can distinguish a septic hip from an aseptic cause, they may not apply to a septic knee. We aimed to identify predictors to discriminate septic and aseptic causes of acute knee monoarthritis in children who underwent arthrocentesis. METHODS: We conducted a retrospective cohort study among children who underwent arthrocentesis for suspected septic arthritis of the knee. Collected data included demographic, clinical and laboratory characteristics. We performed univariate and multivariable analyses to identify predictors of the septic knee. We further investigated accuracy of different predictive models. RESULTS: A total of 60 patients who underwent arthrocentesis for suspected knee septic arthritis were included in this study. Septic arthritis of the knee was confirmed in 32 (53%) patients. Age ≤ 5 years (OR 4.237, [95% CI 1.270-14.127], p = 0.019), WBC > 12,000 cells/mm3 (OR 5.059, [95% CI 1.424-17.970], p = 0.012), and CRP > 2 mg/dL (OR 3.180, [0.895-11.298], p = 0.074) were the most important predictors of a septic knee. Three-tier model comprising these three factors (AUC 0.766) and 4-tier model with addition of fever >38.5°C (AUC 0.776) performed better than Kocher criteria (AUC 0.677), modified Kocher criteria (AUC 0.699) and Full Model (adding age ≤ 5 years and CRP >2 mg/dL to Kocher criteria) (AUC 0.746). Full Model successfully ruled out septic arthritis if all 6 criteria were negative. CONCLUSION: Based on these findings, we propose an algorithm to identify low, intermediate and high-risk patients for knee septic arthritis. Our proposed two-step algorithm incorporating major (age, WBC, CRP) and minor (fever, ESR, non-weight bearing) criteria can serve as a simple decision-support tool to justify arthrocentesis in children with suspected knee septic arthritis.

RESUMO

A articulação temporomandibular está vunerável a várias condições de anormalidades já bastante conhecidas, dentre elas, o deslocamento do disco articular sem redução, considerado pela literatura o mais comum das patologias desta região. A deterioração do quadro pode ser um indicativo da necessidade cirúrgica. Em específico, no deslocamento de disco sem redução, o reposicionamento definitivo pode ser adquirido através de discopexia e artrocentese. O presente trabalho tem como objetivo relatar um caso clínico de deslocamento de disco articular bilateral sem redução, apresentando a importância da fisioterapia associada à abordagem cirúrgia na recuperação da função mandibular, bem como, reforçar a importância de uma abordagem conjunta entre análise clínica e imaginológica para resolução de casos. Paciente feminino cursando com diversos sintomas em face e pescoço de forma progressiva ao longo de dois anos foi submetida a cirurgia na articulação temporo-mandibular, onde foi feita a discopexia através de ancoragem dos discos articulares com parafusos. A avaliação física, assim como, a imaginológica, ajudaram na confirmação do diagnóstico. A abordagem cirurgica adotada no tratamento deste caso foi descrita na literatura desde o final do século XIX. Conclui-se que, o método utilizado no tratamento do deslocamento de disco sem redução deve ser baseado nos sinais e sintomas do paciente, cuja abordagem deve ser readequada de acordo com as mudanças do quadro apresentado. Nesta análise, a abordagem cirúrgica associada à fisioterapia específica para as estruturas musculoesquelética da face trouxeram resultados positivos(AU)


The temporomandibular joint is responsible for several well-known conditions of abnormalities, among them, the joint disc displacement without reduction, considered by the literature the most common pathology of this region. Deterioration of the condition may be indicative of surgical need. Specifically, in displacement disc without reduction, definitive repositioning can be achieved through discopexy and arthrocentesis. The aim of the present study is to report a case of unilateral articular disc displacement without reduction, as well the importance of physiotherapy associated with the surgical approach in the recovery of mandibular function, as well as reinforcing the importance of a joint approach between clinical and imaging analysis for case resolution. Female patient with several symptoms in the face and neck progressively over two years, underwent surgery in the temporomandibular joint, where discopexy was performed by anchoring the articular discs with screws. The physical assessment, as well as the imaging, helped to confirm the diagnosis. The surgical approach adopted in the treatment of this case has been described in the literature since the end of the 19th century. In conclusion, the method used to treat articular disc displacement without reduction should be based on the patient's signs and symptoms, whose approach should be readjusted according to the changes in the presented picture. In this analysis, the surgical approach associated with specific physiotherapy for the musculoskeletal structures of the face brought positive results(AU)

RESUMO

Temporomandibular joint disorders (TMDs) are ailments affecting the jaws and allied structures, resulting in many pathologies (TMJ hypermobility, internal disc derangement, bone changes, degenerative disorders, and ankylosis). Pain, clicking or crepitus, restricted range of motion, deranged jaw function, and deflected or deviated mouth opening and closing are the commonly observed manifestations in TMDs. Internal derangement refers to an aberrant relation of the articular disc to the condyle and fossa, respectively. Conventional therapies highlight the role of non-invasive conservative treatment strategies, namely joint unloading, anti-inflammatory drugs, and physiotherapy. Current literature has emphasized the use of corticosteroids and platelet-rich plasma (PRP) as treatment strategies in TMDs. This study aimed to evaluate whether intra-articular injection of PRP after normal saline lavage in TMJ minimizes the symptoms of TMDs, as compared to injection of normal saline. Thirty patients with TMD according to research diagnostic criteria (RDC) were selected. One group received arthrocentesis with normal saline, and the other group received arthrocentesis with PRP injection. The patients were assessed for pain, maximum inter-incisal mouth opening, bite force, and TMJ sounds. TMDs treated by PRP injection had slightly better results. More studies are required to substantiate the outcome. Injections of PRP were more effective in reducing the symptoms than arthrocentesis with normal saline.

RESUMO

The knowledge gap regarding the topography and anatomy of the dromedary's carpal joint must be bridged to improve diagnostic and treatment procedures such as ultrasonography, arthrocentesis, and arthroscopy. Thirty-five distal forelimbs were harvested from 21 dromedaries and studied through gross dissection, casting, ultrasonography, and computerized tomography. Representative three-dimensional models of the joint cavities, recesses, and pouches were obtained using various casting agents. The safety and feasibility of different arthrocentesis approaches were evaluated. This study provides a detailed description of dorsally located joint recesses and palmarly located joint pouches. The dorsomedial and dorsolateral approach is recommended for arthroscopy and arthrocentesis of the radiocarpal and intercarpal joint when the carpus is flexed. However, caution must be exercised during these approaches to prevent needle injury to the articulating cartilage. Caution is necessary to prevent the formation of inadvertent communication between the dorsally located tendon sheaths and joint cavities. Arthrocentesis via the lateral approach to the lateropalmar pouch is the most favourable approach for the radiocarpal joint. A subtendinous synovial bursa was found between the lateropalmar pouch of the radiocarpal joint and the extensor carpi ulnaris muscle. The subtendinous synovial bursa must be considered during the lateral arthrocentesis approach. The palmar approach is not recommended for arthrocentesis due to the high risk of injury to nerves, veins, and arteries located palmarly.

RESUMO

PURPOSE: The benefit of adjuvant medications, such as platelet-rich plasma (PRP) and hyaluronic acid (HA), following arthrocentesis remains controversial. The purpose of this study was to evaluate the efficacy of PRP and HA injection following arthrocentesis in subjects with symptomatic temporomandibular joint osteoarthritis (TMJ-OA). METHODS AND MATERIALS: The authors implemented a prospective randomized single-blinded pilot clinical study. Healthy adults diagnosed with TMJ-OA who were treated with nonsurgical treatments initially, but failed to respond, participated in this study. Subjects were randomly allocated to HA, PRP, or combined HA+PRP groups following arthrocentesis. The primary outcome variable was the change in pain at 1 and 6 months postoperatively, using the Visual Analogue Scale (VAS). The secondary outcome variables were the changes in maximum mouth opening (MMO), lateral and protrusive mandibular movements, and pathologic TMJ sounds at 1 and 6 months postoperatively. Descriptive and bivariate statistics were computed. The significance level was set at P value < .05, using SPSS 19. RESULTS: A total of 30 consecutive patients (15 males and 15 females) with a mean age of 29.63 ± 8.34 years were followed for 6 months in this study. The mean reduction in pain at 6 months was 4.1 ± 0.9, 4.1 ± 1.1, and 5.1 ± 1.0 for HA, PRP, and HA/PRP, respectively (P < .05). In all 3 treatment groups, mean VAS parameters had significantly reduced after treatment and these postoperative values were significantly lower in the PRP+HA group (P < .001). The mean increase of MMO after 6 months was 8.0 ± 2.8, 8.0 ± 3.0, and 10.1 ± 3.3 for HA, PRP, and HA/PRP, respectively (P < .05). MMO, lateral, and protrusive mandibular movements significantly improved after treatment in all 3 groups (P < .001). TMJ noises were significantly reduced in all treatment groups (P < .001), but the PRP+HA group exhibited a greater reduction. CONCLUSION: Combined HA and PRP injection following arthrocentesis is more effective than HA or PRP alone in the management of TMJ-OA.

RESUMO

Arthrocentesis plus intra-articular hyaluronic acid (HA) injection for temporomandibular joint (TMJ) disorders is known to be a safe and minimally invasive surgical procedure. Arthrocentesis plus HA injection has a pain-reducing effect on TMJ disorders. It is also a palliative treatment that yields positive results in terms of clinical findings such as clicking and mouth opening. Even though some complications have been reported after the performance of this highly successful procedure, the development of bilateral TMJ dislocation after arthrocentesis plus intra-articular HA injection has not been reported to date. This case report presents bilateral TMJ dislocation following arthrocentesis plus intra-articular HA injection that developed within a few hours and resisted manual Hippocrates manoeuvre in a 21-year male. Herein, his treatment with systemic corticosteroid therapy, myorelaxant and anti-inflammatory drugs is also presented. Key Words: Arthrocentesis, Hyaluronic acid, Joint dislocation, Temporomandibular joint, Steroids.

RESUMO

Temporomandibular disorders (TMD) impact a significant proportion of the population. Given the range of management strategies, contemporary care should be evidence-informed for different TMD types. A knowledge-to-action rapid review of systematic reviews published in the past 5 years and guidelines published in the past 10 years concerning the management of TMD was conducted. The Cochrane, Embase, MEDLINE, PEDro, and PubMed databases were searched. A qualitative data analysis was undertaken, with quality assessment completed using the AMSTAR 2 checklist. In total, 62 systematic reviews and nine guidelines considering a range of treatment modalities were included. In concordance with current guidelines, moderate evidence supports a multi-modal conservative approach towards initial management. Contrary to existing guidelines, occlusal splint therapy is not recommended due to a lack of supporting evidence. The evidence surrounding oral and topical pharmacotherapeutics for chronic TMD is low, whilst the evidence supporting injected pharmacotherapeutics is low to moderate. In concordance with current guidelines, moderate quality evidence supports the use of arthrocentesis or arthroscopy for arthrogenous TMD insufficiently managed by conservative measures, and open joint surgery for severe arthrogenous disease. Based on this, a management pathway showing escalation of treatment from conservative to invasive is proposed.

RESUMO

Arthrocentesis of the knee is a procedure in which a needle is inserted into the knee joint, and synovial fluid is aspirated. An arthrocentesis can be diagnostic or therapeutic. Synovial fluid may be removed for testing to determine the nature of the knee effusion. If septic arthritis is suspected, urgent arthrocentesis before initiation of antibiotic treatment is indicated. Moreover, arthrocentesis can also aid in diagnosing crystal-induced arthritis such as gout or pseudogout, or non-inflammatory arthritis such as osteoarthritis. Identifying the cause of the knee effusion can guide treatment. Furthermore, removing fluid from a knee can reduce intraarticular pressure to decrease pain and improve range of motion. There is no absolute contraindication to performing this procedure, but in selecting the needle entry site, an area of skin that is infected should be avoided. Therefore, caution should be exercised when a patient presents with suspected cellulitis over the knee joint to avoid the potential risk of causing iatrogenic septic arthritis. A knee that has undergone arthroplasty should be assessed for arthrocentesis by an orthopedic surgeon. Arthrocentesis of the knee is typically performed with the patient supine. The site for needle insertion is marked, and then the skin is disinfected. After a local anesthetic is administered, a needle is inserted along the pathway that was anesthetized. Synovial fluid is aspirated, and then the needle is withdrawn. Pressure is applied until any bleeding stops. The synovial fluid can be analyzed for infection and inflammation but cannot directly confirm a diagnosis of internal derangement or autoimmune causes of arthritis. In addition to the history and physical examination, laboratory findings and imaging can clarify the etiology of a knee effusion.

RESUMO

AIM: Complete arthrocentesis of the effusive knee ameliorates patient pain, reduces intra-articular and intraosseous pressure, removes inflammatory cytokines, and has been shown to substantially improve the therapeutic outcomes of intra-articular injections. However, conventional arthrocentesis incompletely decompresses the knee, leaving considerable residual synovial fluid in the intra-articular space. The present study determined whether external pneumatic circumferential compression of the effusive knee permitted more successful arthrocentesis and complete joint decompression. METHODS: Using a paired sample design, 50 consecutive effusive knees underwent conventional arthrocentesis and then arthrocentesis with pneumatic compression. Pneumatic compression was applied to the superior knee using a conventional thigh blood pressure cuff inflated to 100 mm Hg which compressed the suprapatellar bursa and patellofemoral joint, forcing fluid from the superior knee to the anterolateral portal where the fluid could be accessed. Arthrocentesis success and fluid yield in mL before and after pneumatic compression were determined. RESULTS: Successful diagnostic arthrocentesis (≥3 mL) of the effusive knee was 82% (41/50) with conventional arthrocentesis and increased to 100% (50/50) with pneumatic compression (P = .001). Synovial fluid yields increased by 144% (19.8 ± 17.1 mL) with pneumatic compression (conventional arthrocentesis; 13.7 ± 16.4 mL, pneumatic compression: 33.4 ± 26.5 mL; 95% CI: 10.9 < 19.7 < 28.9 mL, P < .0001). CONCLUSIONS: Conventional arthrocentesis routinely does not fully decompress the effusive knee. External circumferential pneumatic compression markedly improves arthrocentesis success and fluid yield, and permits complete decompression of the effusive knee. Pneumatic compression of the effusive knee with a thigh blood pressure cuff is an inexpensive and widely available technique to improve arthrocentesis outcomes.

RESUMO

PURPOSE: Since its implementation, temporomandibular joint (TMJ) arthrocentesis can be performed with cannulas of different diameters. The aim of this study was to determine the differences in cannula diameter for TMJ arthrocentesis on intraoperative and postoperative parameters. METHODS: A prospective randomized clinical study was conducted using the documentation of Wilkes stage 3 patients with TMJ disorders. Patients were assigned to 2 groups using a system of computer-assisted randomization. Double puncture arthrocentesis (DPA) was performed with 21-gauge cannulas (group 1) and 18-gauge cannulas (group 2). The primary predictor variable was cannula diameter. Pain values assessed using a Likert-type (0 to10) visual analog scale (VAS) were selected as primary outcome variable. Mandibular movements including maximum mouth opening (MMO), lateral excursions (LE) and protrusion (P), were selected as secondary outcomes. Mandibular movements and pain values were recorded before treatment and at 1st day and 3rd months intervals. Descriptive, comparative, and bivariate analyses were conducted. Intraoperative complications were also recorded. RESULTS: DPA was applied to 33 patients (29 females, 4 males). Although group 1 was found to be significantly more advantageous than group 2 in terms of pain levels (P < .05), no statistically significant difference was discovered in terms of total complication numbers and mandibular movements at the follow-up periods (P >.05). CONCLUSIONS: Despite the limited sample size cannula thickness affects postoperative pain level significantly in conventional TMJ arthrocentesis.

RESUMO

OBJECTIVES: Arthrocentesis is commonly performed in the emergency department, but success rates vary based on location. Presently, there is a paucity of data assessing the utility of ultrasound-guided (USG) medium-sized joint arthrocentesis. The objective of this study was to compare the success of USG and landmark-guided (LMG) medium-sized joint arthrocentesis. METHODS: This was a single-center, prospective, randomized clinical trial (NCT03327584) of a convenience sample of adult patients who presented to an urban, university hospital with > 105,000 visits annually. Patients with a suspected medium-sized joint effusion (defined as elbow, wrist, or ankle) undergoing arthrocentesis were randomized into LMG or USG using the GE Logiq e linear transducer (4-10 MHz). The following patients were excluded: on anticoagulation, with soft tissue infection overlying the joint, or involving an artificial joint. Statistical analysis included the Fisher exact, Mann-Whitney U-test, and t-test. RESULTS: Overall, 44 patients were enrolled with 23 patients randomized into the LMG group and 21 patients into the USG arm. USG was significantly better than LMG with an overall success of 94.1% versus 60% for LMG (difference = 34.1%, 95% confidence interval [CI] = 4.90 to 58.83). USG first-pass success was 82.4% versus 46.7% for LMG (difference = 35.7%, 95% CI = 2.76 to 60.37) and a mean of 1.35 attempts versus 2.00 for LMG (difference = 0.65, 95% CI = 0.005 to 1.296). Of the 14 LMG failures, eight had no effusion present on USG crossover. Four patients in the USG group had no effusion present. CONCLUSIONS: Ultrasound guidance improved first-pass and overall successful arthrocentesis of medium-sized joint effusions.

RESUMO

OBJECTIVE: The present double-blind randomized clinical trial aimed to compare the efficacy of conservative treatment and articular lavage, either alone or combined, to reduce joint pain and improve mandibular opening. STUDY DESIGN: The sample consisted of patients presenting with limited mouth opening and joint pain. The diagnosis was made according to the diagnostic criteria for temporomandibular disorders guideline and confirmed by magnetic resonance imaging. Sixty patients were selected and randomly allocated to 4 groups of 15 patients each with different treatments: group A (conservative), group B (conservative + medication), group C (arthrocentesis), and group D (arthrocentesis + medication). The groups were compared in terms of maximal interincisal opening and pain. RESULTS: The average age of the patients was 34.17 ± 13.1 years, 88.1% were women, 72.9% had internal derangement, 54% had joint sounds, and 55.9% presented with locking. Clinical improvement was noted in all parameters compared with baseline in all groups (P < .005), but no significant differences were observed when the groups were compared (P > .05). CONCLUSIONS: Both arthrocentesis and conservative modalities were efficient treatments to reduce joint pain and increase mandibular opening.

RESUMO

OBJECTIVE: To compare clinical and imaging results of two needles arthrocentesis (TNA) versus double-needle cannula arthrocentesis (DNCA) in the treatment of temporomandibular joint disc displacement (DD). METHODS: Twenty patients with DD were randomly divided into two groups: TNA and DNCA. Clinical data (pain scores; maximal interincisal distance [MID], and protrusion and laterality movements) were evaluated before and 24 months after the arthrocentesis. Disc and condyle position and joint effusion (JE) were evaluated by magnetic resonance exams. RESULTS: Both groups presented improvement in the MID, including pain reduction, modifications in disc and condyle positions, and reduction of the presence of JE, without difference between groups (p > 0.05). The DNCA was performed significantly faster (p = 0.0001). CONCLUSION: Both TNA and DNCA are efficient in promoting improvement in the MID: reduction in pain, modifications in disc and condyle positions, and, in part, may account for less JE, without difference between techniques.

RESUMO

The aim of this study was to investigate the clinical course of masticatory function recovery following arthrocentesis. Patients with a unilateral condylar head fracture who underwent arthrocentesis for therapeutic reasons were evaluated and compared with patients with a unilateral condylar head fracture who did not undergo arthrocentesis. At 3 months after treatment, the occlusal contact area and maximum bite force in patients with a fracture treated with arthrocentesis were greater than in those who did not receive arthrocentesis at the same time points, although the differences were not significant. Moreover, at 1 and 3 months following arthrocentesis, mean (±SD) occlusal contact area (1 month: 1.99 ± 0.55 mm2, p = 0.01; 3 months: 2.90 ± 1.36 mm2, p = 0.03) and maximum bite force (1 month: 82.45 ± 15.04 N, p = 0.01; 3 months: 101.11 ± 14.53 N, p = 0.01) on the fractured side in patients who underwent that treatment were significantly reduced when compared with those on the non-fractured side. The authors conclude that if the priority is to avoid open reduction and internal fixation, then the arthrocentesis approach might be a less invasive alternative, albeit with the price of a prolonged healing interval.
