Conditions

Temporomandibular Disorders (TMD), Temporomandibular Joint Disc Displacement, With Reduction

Brief summary

Temporomandibular disorders (TMD) are common conditions in society, characterised by symptoms such as pain, limited movement and joint noises, which negatively affect an individual's quality of life. The primary goal of treatment is to restore the physiological functions of the joint by eliminating the aetiological factors. In cases where conservative methods prove ineffective, arthrocentesis, a minimally invasive approach, comes to the fore. Arthrocentesis aims to reduce pain by removing inflammatory mediators and to increase joint mobility. In this study, the intraoperative parameters and clinical outcomes of different arthrocentesis techniques were compared and evaluated in patients with Wilkes stage 2-3 TME disorders.

Detailed description

Introduction: Temporomandibular disorders (TMD) are common symptoms in society, characterized by pain, limited movement, and all sounds, which are often negatively impacted by individual life circumstances. The primary goal of treatment is to eliminate the etiological factors and restore the replaceable functions of the parts. Arthrocentesis, a minimally invasive approach, is emphasized in cases where conservative treatment is beneficial. Arthrocentesis reduces pain by removing inflammatory mediators and increases joint mobility. This effective treatment was evaluated by comparing the intraoperative parameters and clinical success of different arthrocentesis techniques in patients with Wilkes stage 2-3 TMJ disorders. Materials and Methods: This study is being conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Karadeniz Technical University. Fifty patients (Group 1: n=25, Group 2: n=25) treated with two different arthrocentesis technologies were enrolled retrospectively. The first group was the study of Mun et al. Arthrocentesis was performed using the method employed by Rahal et al., which consisted of two 22-gauge needles bent to form a "Y" shape and placed simultaneously and concentrically. The second group underwent arthrocentesis using a fabricated Y-shaped cannula used by Rahal et al. Each treatment was performed under local anesthesia, and the upper regions were irrigated with an average of 100 ml of Ringer's lactate solution. Following arthrocentesis, 1 ml of hyaluronic acid was injected into the patients. Preoperative and postoperative values were evaluated by comparing the groups at 1 to 6 months. Furthermore, intraoperative arthrocentesis efficiency (number of needle insertions, procedure time, complication rate, and treatment tolerance) was compared between the groups.

Interventions

PROCEDUREY-shaped cannula with a source

Y-shaped cannula with a source Arthrocentesis performed by simultaneously and concentrically placing two manually Y-shaped bent needles into the joint cavity.

PROCEDUREY-shaped cannula without a source

Y-shaped cannula without a source Arthrocentesis performed by simultaneously and concentrically placing two manually Y-shaped bent needles into the joint cavity.

Intervention model description

Arthrocentesis was performed on the first group using a method developed by Mun et al., involving two 22-gauge needles bent to form a 'Y' shape with the tips facing each other, and on the second group using a factory-made Y-shaped cannula developed by Rahal et al.

Design outcomes

Primary

MeasureTime frameDescription
TMJ Painbefore the procedure, at 1 month and at 6 monthsTMJ Pain intensity was assessed using the Visual Analog Scale (VAS). The VAS ranges from a minimum score of 1 to a maximum score of 10, where 1 indicates the best condition (no pain) and 10 indicates the worst condition (maximum pain). Higher scores on the scale represent greater pain severity. Accordingly, an increase in the score reflects a higher level of perceived pain by the patients.
