Hyaluronic acid application vs arthroscopy in treatment of internal temporomandibular joint disorders

Abstract

AIMS: The goal of this study was to compare the treatment outcome after two different treatment modalities in cases of disc displacement of the temporomandibular joint diagnosed via magnetic resonance technique, namely surgical procedure in form of arthroscopic lysis and lavage vs. hyaluronic acid superior joint space application. MATERIALS AND METHODS: Magnetic resonance imaging was performed before and one year after treatment. Simultaneously, pre-and post-treatment visual analogue scales and maximal mouth opening distance were documented. RESULTS: In our study, out of the total of 145 patients who were initially diagnosed with magnetic resonance imaging to have internal derangements and treated with arthroscopic lysis and lavage or hyaluronic acid application, we observed progression of internal derangement in 27 cases (18.6 %), improvement in 37 cases (25.5 %) and stationary state in 81 patients (55.9 %). Both treatment methods signifi cantly improved the followed maximal mouth opening distance and visual analogue scale, as confi rmed upon the 12-month follow-up examination. Maximal mouth opening was 4.7mm for hyaluronic acid application and 12.2mm for arthroscopic lysis and lavage (p < 0.005). The mean visual analogue scale values decreased from 6.2 to 2.1 for hyaluronic acid application and from 6.9 to 1.2 for arthroscopic lysis and lavage (p < 0.005). CONCLUSION: Our study shows that both arthroscopic lysis and lavage and hyaluronic acid injections are effective and safe in the treatment of disc displacement in the temporomandibular joint (Tab. 3, Ref. 30).

Current Clinical Research Directions on Temporomandibular Joint Intra-Articular Injections: A Mapping Review

“…There is a steady upward trend in the number of primary studies on HA published in subsequent years. The primacy of HA from 2021 seems to be threatened by centrifuged blood products, but this group of substances is heterogeneous and cannot be compared to HA in terms of effectiveness as a whole [18,19,22,25,38,43,49,51,54,[58][59][60]63,68,70,71,74,75,78,80,80,82,86,88,89,[91][92][93]95,[98][99][100][101][102]105,106,110,[113][114][115][116][117]120,121,124,126,127,129,130,…”

Role of female reproductive hormones and genetics in temporomandibular joint disorders

“…Compared to men, women exhibit a three-fold higher susceptibility to developing temporomandibular joint disorders such as TMJ disc displacement (malposition of the disc in relation to the mandibular condyle and articular eminence (5)) and arthralgia (6,7,8). This level of prevalence can stem from specific characteristics unique to the female population, including greater intraarticular pressure and joint laxity, smaller joint space and higher levels of TMJ pain, potentially influenced by estrogen (9).…”
