Clinical and intra‐operative factors affecting the outcome of arthrocentesis in disc displacement without reduction: A retrospective study

Abstract

Background Temporomandibular disorder (TMD) is a group of disease which affects the temporomandibular joint (TMJ) and supporting tissues of the musculoskeletal structures. Arthrocentesis is an effective treatment modality for TMD, especially in patients who suffer from pain and limited mouth opening. Objective The aim of this study was to investigate the effects of pre‐operative and intra‐operative variables on the clinical outcome of arthrocentesis therapy. Methods The records of 83 patients diagnosed as disc displacement (DD) without reduction according to DC/TMD, and treated with arthrocentesis were selected. Sex, age, bruxism history, pain intensity and maximum mouth opening (MMO) were recorded as pre‐operative variables. Extravasation and the amount of irrigation were recorded as intra‐operative variables. The success of the arthrocentesis procedure was determined as MMO <35 mm and pain intensity lower than 3, at third‐month follow‐up. Results At 3‐month follow‐up, clinical evaluation showed a significant reduction in TMJ pain and an increase in MMO (P < 0.05). It was found that patients with an unsuccessful outcome are those who had a more restricted MMO and severe pain before the procedure. Extravasation was found to be a significant factor that affects the success of the procedure. Conclusion The success of arthrocentesis in TMJ DD without reduction is adversely affected by the severity of the pre‐operative clinical symptoms. Extravasation is also a factor that has a negative effect on the success of the procedure.

Evaluation of Influence of Arthroscopy on the Range of Mandibular Movements Based on Medical Records

“…In our study, there was the prevalence of the female sex among patients, which was corroborated by the findings of several studies. 10,[17][18][19][20][21][22] In the present study, a mean age of patients of 32.2 years (16-61) was shown, which coincided with 2 studies that found a mean age of 20 to 40 years. 10,14,17,21,22 Although TJDS span all age groups, they generally affect the age-range from young people to middle-aged adults.…”

Evaluation of Patient Comfort and Impact of Different Anesthesia Techniques on the Temporomandibular Joint Arthrocentesis Applications by Comparing Gow-Gates Mandibular Block Anesthesia with Auriculotemporal Nerve Block

“…Nishimura et al [ 25 ] described the MMO value of more than 38 mm, and mild or no pain scores were counted as successful procedures in their study. Bas et al [ 26 ] accepted the MMO value of more than 35 mm and VAS pain scores of lower than 3 were accepted as successful at the 3 rd month follow-up in their study. When considered the success rate of pain and MMO values independently, it was assessed as 91% and 79.5%, respectively.…”

Temporomandibular joint arthrocentesis: a technique proposal. Case report

“…The efficiency of this process is accentuated by the vacuum pump, that also promotes other benefits already mentioned. Also, it can possibly reduce the risk of extravasation of solution used during irrigation, that already has been associated with a negative effect on the success of the procedure 16 .…”
