Manual Therapy and Kinesio Taping on Temporomandibular Joint Dysfunction Following Oral Surgeries

Description

Oral surgery concerned with the diagnosis and surgical treatment of congenital or acquired diseases, dysfunction, defects or injuries of the mouth and jaw. Oral surgeries include various types such as impacted wisdom tooth surgery, oral cyst enucleation (cystectomy), surgical incision and drainage of odontogenic abscess, oral tumor excision and open reduction and internal fixation of mandibular fracture (ORIF).

Temporomandibular joint dysfunction: It is one of post operative complications that occur post oral surgeries which include several symptoms as pain,edema and trismus. Pain is the most common and limiting clinical manifestation of this dysfunction, as well as decreased mobility of the jaw, both of which impacts quality of life. The multifactor etiology of temporomandibular joint dysfunction often requires multidisciplinary healthcare professionals to manage difficult symptoms, including chronic pain. Many studies have identified a variety of conservative interventions, such as physical therapy, for patients with temporomandibular joint disorders, including joint mobilization, tissue mobilization,dry needling, friction massage, patient education, splints, modalities, stretching, coordination activities,strengthening exercises, and combinations of these techniques. postoperative major complications such as pain, edema and trismus in various oral surgeries such as tooth extraction, maxillary expansion, and orthognathic surgeries. Oral surgical procedures are often accompanied by a multitude of complications including pain, swelling, and morbidity. These are the result of inflammatory processes induced by the surgical wound healing.

Facial edema: During surgeries, inflammatory chemicals such as prostaglandins, leukotrienes, bradykinins, and platelet-activation factors are secreted by damaged tissue. Moreover, excessive lymph production causes disturbances in local lymphatic circulation. Inflammatory chemicals create endothelial gaps to increase vascular permeability. In addition, macrophages and mast cells in damaged tissues produce histamine, serotonin, and eicosanoids; alter the local constitution of blood vessels; and release nitric oxide, eventually resulting in vasorelaxation. These chain reactions increase blood vessel relaxation and vascular permeability and result in the accumulation of interstitial fluid, eventually resulting in tissue swelling and pain.

Trismus: It is defined as prolonged tetanic spasm of masticatory muscles of jaw. the transient jaw stiffness usually reaches its peak on the 2nd day post surgery. It is diagnosed from clinical examination of the maximal interincisal distance (MID) <40-45 mm caused by contracture and not by obstructive joint impingement.The factors contributing to trismus are: (1) Multiple needle penetrations correlate with a greater incidence of post injection trismus. (2) Elevation of flap beyond the external oblique ridge. (3) At times, the patient hurts his/her own tongue or cheek under the effect of anesthesia resulting in reflex trismus.

kinesio taping (KT) was developed by the Japanese therapist and academic lecturer. More than 30 years ago, he created a special tape, which by the correct application, i.e. sticking with a small stretch (about 15%) to the skin, raises the surface of the skin, thereby increasing the space between the dermis and fascia . The expansion of this space, should reduce lymph retention. The patch used for this method has a thickness and weight similar to skin. The waterproof tape is made of 100% cotton, while the adhesive on the inside is applied in the shape of a fan strip, which allows the air to flow. When stretched beyond its normal length and applied, it recoils and creates a pulling force on the skin, thus improving blood and lymph flow by alleviating hemorrhage and congestion of lymphatic fluid.

Manual therapy (MT) is one of the various types of interventions for treating patients with temporomandibular joint dysfunction and include: Mobilization exercise stretching exercise, coordination exercise, rang of motion exercise and strengthening exercise. Within other body regions, manual therapy intervention has been detailed and summarize the efficacy of treatment approaches.Strengthening, stretching/flexibility, and motor control exercises have demonstrated to be efficacious in reducing pain and disability in patients with chronic low back pain,as well as mechanical neck pain. Despite a review and meta-analysis the efficacy of exercise therapy and dosage has yet to be determined for patients with temporomandibular joint dysfunction. exercises intended to increase mobility of the temporomandibular joint and/or muscles of the jaw. Exercise therapy aims to reduce clinical symptoms such as pain in the muscles and joints, and improve motor function by moving whole or part of the body.Exercise can be classified into self exercise by patients and manual therapy that physiotherapists apply to patients. Self exercise is often offered as home exercise or self-care program that can be done at home. manual exercise therapy includes mobilization, stretch,muscle strengthening exercise and coordination exercise.
