简要总结

There are several studies that have considered Botulinum toxin A (BoNT-A) injections are effective in treating symptoms for Temporomandibular Joint (TMJ) disorders. BoNT-A injections improve the hyper-tonicity of mandibular muscles and its consequent joint load reduction. Also injections of BoNT-A, for patients with articular disc displacement, resulted in pain relief and return of the normal movements of the mandible. The main goal of this study is to test the beneficial impact of BoNT-A injections in the masticatory muscles of patients submitted to TMJ surgical arthroscopy.

详细描述

Study Objective:

To investigate the potential performance of incobotulinumtoxin-A (BTXA) in patients submitted to TMJ surgical arthroscopy. Besides the acceptable good outcomes of TMJ arthroscopy, the authors believe that using a single injection of BTXA into the temporalis and masseter muscles could reduce joint loading and pain, improving TMJ arthroscopy results.

The proposed explanation for this study:

TMJ arthroscopy is a minimal invasive surgical technique for different types of temporomandibular joint (TMJ) internal derangements. Besides the acceptable outcomes of TMJ arthroscopy, the authors believe that adding to this treatment a single injection of BTXA into the temporalis and masseter muscles could reduce joint loading, improving TMJ arthroscopic results.

盲法说明

atients with inclusion criteria will be seen in an orofacial pain session and assessed for pain using the VAS scale, by scoring the degree of pain between 0 (absence of pain) and 10 (maximum pain). Then the patients are proposed for TMJ arthroscopy. The nurse enters the room with the patient and asks to the patient to choose an envelope. In this moment, the envelope is placed on a table and the patient writes his name. The nurse accompanies the patient to the doctor's office. Alone, the nurse opens the envelope and sees the code and the indication of PLACEBO or BTXA. Then, she will prepare in her room, isolated from the whole team, 2 syringes. She will put the envelope in a bag and deliver a tray with 2 syringes for treatment and a code to identify the patient in the treatment room. The doctor injects the syringes according to the protocol.

干预措施: Incobotulinumoxin A (Drug)

IncobotulinumoxinA

Active Comparator

TMJ arthroscopy and Dose of IncobotulinumoxinA to be injected 100 U distributed in 2 syringes with 1 ml each: 25U (0.5ml) in Right Masseter / 25U (0.5ml) in Left Masseter / 25U (0.5ml) in Right Temporalis / 25U in Left Temporalis.

结局指标

主要结局

VAS score

时间窗: 5 weeks after injection and TMJ arthroscopy

Improvement in TMJ pain: measured by the patient using a Visual Analogue scale (VAS), with a range from 0 to 10, with 0 being no pain and 10 having maximum unbearable pain. VAS score will be measured every week before surgery and in the fifth week after surgery.

次要结局

  • Muscle Tenderness(5 weeks after injection and TMJ arthroscopy)
  • GICS(5 weeks after injection and TMJ arthroscopy)
  • Maximum Mouth Opening(5 weeks after injection and TMJ arthroscopy)
  • Palpable joint click(5 weeks after injection and TMJ arthroscopy)
  • Diet consistency tolerated(5 weeks after injection and TMJ arthroscopy)
