Temporomandibular disorder (TM) is a common type of temporomandibular disorder. In different populations and with different methods of investigation, about 20% to 40% of people suffer from occlusal abnormalities (TMD), and women are higher than men. It is mainly characterized by maxillofacial pain, murmur of the jaw opening and closing joints, and abnormal jaw movements. TMD is a common and multifaceted disease that involves different departments. We hope that physicians in all departments will recognize the disease and understand it, although they will not treat it, so that misdiagnosis can be avoided. Orthopedics commonly misdiagnosed cervical spondylosis patients taking X-rays often show: cervical spine osteophytes, intervertebral narrowing, cone slippage, etc. Even further CT and MRI examinations also have the above changes, and orthopedic surgeons are prone to mistakenly believe that this leads to compression of the anterior cervical spinal nerve, followed by a series of the above symptoms. Physiotherapy, acupuncture, etc. are often given, but the effect is poor with repeated attacks. After treatment of these patients, the “cervical spondylosis” has disappeared. A small number of patients with TMD are often admitted to hospital with a misdiagnosis of cervical spondylosis and are treated with infusion traction but the effect is still not significant. makof-sky suggests that head and neck posture can have an effect on occlusal patterns, either through biomechanical or neuroreflex mechanisms. Studies of TMD and soft tissue pain around the cervical spine have shown that pain in the posterior belly of the bicipital muscle can be transmitted to the mastoid and cause pain in the sternocleidomastoid muscle, and that inadequate blood supply to the neck and spinal nerve involvement, leading to cervical stiffness and dizziness and impaired microcirculation, can cause dental pain. Cervical spine dysfunction can coexist with masticatory muscle dysfunction and affect each other. Clinically, after TMD treatment, the patient’s shoulder and neck muscle soreness and frequent pillow drop disappear. Common misdiagnosis in otolaryngology The temporomandibular joint is composed of condyle, ligament, etc. There is a ligament on the condyle that passes through the hamate neck and hamate to the inner posterior upper part of the joint, called pito’s ligament, and pulling this ligament can cause the movement of the auditory tuberosity and tympanic membrane. When TMD appears, about 75% to 90% of patients have tinnitus, dizziness and vertigo. Some patients show vertigo and dizziness particularly prominently, and some ENT doctors treat it as atypical “Meniere’s syndrome”, and some even treat it surgically with poor results. TMD is also treated in TCM departments for kidney deficiency and tinnitus, which TCM doctors consider to be a kidney problem. Neurosurgery commonly misdiagnoses patients with maxillofacial pain as likely to be seen in ENT departments. Experienced otologists refer to arthroplasty for pain, limited muscle pain and hypersensitivity points, or trigger points, can be palpated within the myofascia. Post-touch agitation of these trigger points can change the way the pain is experienced and result in involvement pain and even headache. Trigeminal nerve pain is mainly manifested in the maxillary and mandibular branches, and touching a point or a part of the nerve causes an immediate onset of pain, as if an electric shock had flashed. Patients are especially afraid of touching this point and are usually given anti-trigeminal nerve pain medications. Most commonly misdiagnosed TMD headaches in neurology present as tension headaches, also known as chronic headaches, where the pain originates from muscles, such as myofascial pain, and is constant and steady dull pain in nature, mostly bilateral in the middle, anterior and lower temporal muscles, and aggravated by irritability. Myoconstriction headache is a sensation of heavy pressure on the head, tightness or wearing a tight hat. The headache tends to last for a long time, day and night, and the patient is restless. A few TMDs can induce migraine headaches, where the pain originates from the neurovascular and is pulsating in nature, unilateral and severe, and may be accompanied by nausea, vomiting, and vertigo. The pathogenesis of migraine involves the central nervous, vegetative and enzymatic systems. Ophthalmology commonly misdiagnoses unexplained ocular pain, soreness and pain in the eye that is examined by ophthalmology but not detected as a problem. tmd presents with limited myalgia that produces symptoms to the eye through trigeminal nerve traction firing. Ophthalmology is also unable to diagnose the pain and soreness of the eye caused by TMD. There is also reflex distal pain, and most scholars believe that dental occlusion and nerve factors are the main causes of distal pain in the patient’s low back. And who in the patient would think in the direction of dental occlusion? Blindly finding different specialties, doctors have to deal with the symptoms or do nothing about it. Muscle pain is commonly misdiagnosed in stomatology, and myofascial pain can be transmitted to the teeth through retraction counterconduction. One patient’s tooth was opened and sealed with inactivator 4 to 5 times, and the patient still had pain, while the affected tooth did not hurt after the TMD was cured. Psychiatry commonly misdiagnoses TMD patients whose headaches are relieved by treatment and feel pain again at intervals for a long time, repeated attacks without positive results on examination, sleep not improved, insomnia, and neurasthenia patients go to psychiatry. TMD has various forms of clinical manifestations. When patients have not yet developed difficulty in opening and closing the mouth and popping, many physicians in the department do not consider TMD, and patients are not aware of TMD, which leads to misdiagnosis. The variety of clinical manifestations of TMD is the same as that of many specialized diseases, but it is not difficult to confirm the diagnosis after understanding.
