The maxillo-hyoid muscle is aa flat muscular plate located between the lower jaw and the hyoid bone. This muscle is often called the diaphragm of the oral cavity, since it is they who form the bottom of the cavity. The muscle delimits the face and neck.
Above muscular tissues is the salivary gland andlanguage. The beginning of the maxillofacial muscle takes on the lower jaw, is directed backwards, towards the median line. The posterior fascicles of the muscle are attached to the hyoid bone.
The maxillofacial muscle is flat, in the shape of an irregular triangle. On the opposite side is located a similar muscle. Connecting these muscles form a seam.
The exact shape and size of the muscle depends onfeatures of the bone structure of the body. For example, if a person has a lower jaw longer, the muscle has a small width, but its length is more than the average. With a short jawbone, the muscle is wider. Paired cranial-hyoid muscles form the bottom of the oral cavity. The contraction of two muscles simultaneously allows you to lower the jaw.
The jaw-hyoid line is the place wherethe same muscle begins. Between the fascicles of the muscles are formed small cracks. Sometimes through them, infections and purulent congestion from the oral cavity can spread. Slots are more often located directly under the tongue, near the second lower molar.
Muscle innervation is ensured bycranial-hyoid nerve, which passes through a special depression of the lower jaw (mandibular hyoid furrow). The main task of the body is to lower the lower jaw. This occurs only with simultaneous contraction of the paired muscles. Proper functioning allows a person to talk, swallow, chew food. The nutrition of these paired muscles is carried out with the help of cranio-hyoid arteries, which depart from larger lingual and facial.
Sometimes the jaw-hyoid muscle is involved ininflammatory process, which often leads to tissue suppuration. The lesion focus quickly captures new areas, gradually spreading to the entire surface of the muscle. Since all the tissues that form the oral cavity, communicate with each other by blood vessels, the infection can spread to the tongue, nerves, salivary glands. In this case, doctors talk about phlegmon.
Phlegmon most often affects the maxillofacial groove, but it can also be localized in other areas of the bottom of the oral cavity:
If the jaw-hyoid muscle is hurting because of phlegmon, the reasons, most likely, are as follows:
The clinical picture, as a rule, is as follows:
Patients with phlegmon often tilt their head forward, open their mouths, and when sitting rest their chin on a chair, as this facilitates discomfort.
Infection leads to a general intoxication of the body, an increase in temperature, a change in the number of leukocytes in the blood. Often phlegmon leads to respiratory acidosis.
If tissues are located belowjaw-hyoid muscle, small tumors are formed on both sides. The skin above them is tense and hot to the touch. When trying to touch the affected areas, the patient experiences discomfort, and sometimes severe pain. Independent treatment is unacceptable. If symptoms appear, you should immediately make an appointment with a doctor, since the absence of therapy can lead to dangerous consequences. The inflammatory process often spreads to other tissues and organs.
The maxilla-hyoid muscle is amenable to training, ensuring the preservation of the natural face oval. There are several simple exercises:
The key rules for training the neck muscles look like this:
After completing the exercises, you can relax.
Regular training of the maxillofacial andother muscles of the neck allows you to achieve a smooth skin and keep a clear contour of the face, chin. Exercises tonify the body, improve local blood circulation and nutrition of the oral cavity organs.
The effect is noticeable after 2-3 weeks of regularpractitioner. Not being able to visit cosmetologists and masseurs, you can take care of the muscles at home and even during the working day. To do this, it is sufficient to perform 2-3 simple exercises routinely: lifting the chin, rotating the head, tilting.
