Effectiveness of double-puncture temporomandibular joint arthrocentesis with viscosupplementation in different categories of severity - a prospective study

Impact of age on degenerative joint disease of the temporomandibular joint: A systematic review and meta-analysis

BACKGROUND

It is unclear that the influence of age on degenerative joint disease (DJD) of the temporomandibular joint (TMJ).

METHODS

Relevant literature was retrieved from PubMed, Elsevier, Web of Science, and Google Scholar. EndNote 21 was used to consolidate the literature retrieved from these databases. Key information were extracted from the included studies, statistical analysis was performed using Stata 15.0. The quality of the studies was evaluated using the cross-sectional study evaluation criteria recommended by the Agency for Healthcare Research and Quality.

RESULTS

A total of 11 studies involving 2832 participants (1099 males, 1744 females) were included. The incidence of DJD of the TMJ was approximately 35% among individuals aged 20 to 39, 43% among those aged 40 to 59, and 54% among those aged 60-69.

CONCLUSION

Age progression is a key risk factor for the development of DJD of the TMJ. The incidence of DJD of the TMJ increases progressively across different age groups, with a significant rise observed in middle to older age groups.

Update on Evidence and Directions in Temporomandibular Joint Injection Techniques: A Rapid Review of Primary Research

This rapid review summarizes the latest primary research in temporomandibular joint (TMJ) injection treatment. The final literature searches were conducted on 4 January 2024. Selection was performed systematically following predefined eligibility criteria. Randomized control trials concerning the treatment of TMJ disorders with intra-articular injections were included. Studies on more invasive interventions were excluded. Quality of life, joint pain and range of mandibular mobility were assessed. Ultimately, 12 studies covering a total of 603 patients qualified. They concerned: (1) arthrocentesis (AC) and the administration of, (2) injectable platelet-rich fibrin (I-PRF), (3) platelet-rich plasma (PRP), (4) hyaluronic acid (HA), (5) non-steroidal anti-inflammatory drugs (NSAIDs), and (6) hypertonic dextrose (HD) with a local anesthetic. The dominant approach was to perform arthrocentesis before administering the appropriate injection substance (I-PRF, PRP, HA, or NSAID). Two current studies on the intra-articular administration of NSAIDs, specifically tenoxicam and piroxicam, are noteworthy. A mixture of PRP and HA was injected in another two trials. These two innovative approaches may prove to be significant directions for further research on injection treatment of TMJs.

Temporomandibular Joint Minimally Invasive Procedures in the Pediatric Population: A Prospective Study

Over recent years, temporomandibular joint (TMJ) minimally invasive procedures, such as arthrocentesis and arthroscopy, have been appointed as an initial TMJ intra-articular treatment. Both procedures present safe and effective clinical results in managing temporomandibular disorders (TMD) by reducing pain and improving mouth opening. The use of these techniques in adults is validated in the literature. However, data on the safety and effectiveness of minimally invasive TMJ interventions in pediatric patients are scarce. This study aims to investigate the effectiveness of TMJ arthrocentesis and arthroscopy in the pediatric population. A prospective study was conducted at Instituto Português da Face (IPF) in Lisbon, Portugal, including patients treated for TMD from 1 June 2019 to 30 June 2023. In the present study, 26 patients (17 female and 9 male) were included, representing a total of 48 joints operated. A statistically significant reduction was observed in the primary outcome, TMJ pain, from 3.93 ± 2.80 preoperatively (mean ± SD) to 0.50 ± 1.53 (mean ± SD) postoperatively (p < 0.05). An improvement in the secondary outcome, maximum mouth opening, from 36.92 ± 8.79 preoperatively to 42.96 ± 5.07 postoperatively, was observed (p < 0.05). The overall success rate was 84.62%. This prospective study showed that TMJ arthrocentesis and arthroscopy appear to benefit pediatric patients with TMD, significantly lowering pain and improving MMO without relevant postoperative complications.
