Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
All this is sometimes accompanied by headache and other painful symptoms in the neck musculature, incapacitating for many patients and at considerable public health expense. Intramuscular and intra-articular injections of botulinum toxin are a simple treatment that has proven to be effective in the treatment of the painful symptoms of these disorders, being a therapeutic option in situations of failure of conventional treatments, without presenting adverse effects.
Our study presents the preliminary results of twenty patients treated with this therapy
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Adverse effects were also evaluated. In 85% of the patients, pain on oral opening improved and 90% showed improvement of pain on mastication. A 75% of the patients reported improvement in joint clicking/noise. Headaches improved or disappeared in 70% of the patients treated. Despite the limitations of the study and the preliminary results, intramuscular and intra-articular infiltrations with BTX were effective in the treatment of symptoms associated with TMDs, with minimal adverse effects.

TREATMENT
BEFORE TREATMENT/AFTER TREATMENT A 1 cc marked insulin syringe was used for intramuscular injection of the prepared solution, according to the locations and amounts proposed with a total dose of 100 U (Type A toxinum botulinum, Allergan) in each patient, distributed at the different injection sites: 40 U in the masseter muscle, (0.1 cc=10 U), 20 U in the area of greatest hypertrophy (anterior inferior masseter), 10 U in the direction of the mandibular inferior border and 10 U in the area of the posterior inferior masseter; 20 U in the lateral pterygoid muscle (10 U extraorally between the zygomatic arch and sigmoid notch and 10 U intraorally, behind the maxillary tuberosity); 20 U in the TMJ, 10mm anterior to the tragus and 2mm below the zygomatic arch and 20 U in the anterior part of the temporalis muscle.
Botulinum toxin type A injection
The solution for injection was prepared immediately before the intervention, by dissolving the vials of BTX, kept refrigerated at 5ºC, in 1 ml of sterile saline solution at room temperature. Eight injection sites were marked, three located in the masseter muscle, two in the lateral pterygoid muscle, one in the temporomandibular joint (TMJ) and two in the temporalis muscle. A 1 cc marked insulin syringe was used for intramuscular injection of the prepared solution, according to the locations and amounts proposed by Kim et al. and Ho et al. with a total dose of 100 U in each patient.distributed at the different injection sites.
