Hyoid bone fracture

Introduction to hyoid bone fracture The hyoid bone is in the shape of a hoof, consisting of the hyoid bone, the big horn (2) and the small horn (2). It is the main supporter of the tongue, and the thyroid cartilage is located immediately below. The large horn of the hyoid bone has the stem and ligament of the stem and the styloid process of the tibia. Connected. Most of the hyoid bone is located under the skin. The hyoid bone can be congenital malformation, and the ligament of the stem and tongue can be calcified or ossified and connected with the hyoid bone. Normal people before the age of 20 to 30 years old, the tongue and the hyoid bone have no bone joints account for more than 50%. The lingual body and the small horn of the hyoid bone are also separated by cartilage. The ligament of the stem and ligament is calcified or fused with the hyoid bone, or the premature osseous connection is the cause of the fracture. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: difficulty swallowing

Cause of hyoid bone fracture

Causes

More common in the front of the neck, various blunt force contusions, such as boxing injuries, injuries, car accidents, etc., can also be due to violent muscle pull injuries, according to reports in the literature, strong swallowing action and sudden neck overstretch and torsion, Fracture of hyoid bohe.

Hyoid bone fracture prevention

More common in the front of the neck, various blunt force contusions, such as boxing injuries, injuries, car accidents. It can also be pulled by violent muscles. According to reports in the literature, strong swallowing movements and sudden overstretching and torsion of the neck can cause fractures of the hyoid bone.

With simple fixation and treatment with plaster or splint, the wound can heal quickly and there is usually no sequelae after healing. However, if you do not pay attention to it and continue to move, it will easily lead to the re-displacement of crack fractures, and even surgery is needed.

Fracture problems are usually fixed first, then slowly healed, the cycle takes a month, eat more fresh fruit can help the body recover, eat more protein-rich foods can be prevented.

Tongue fracture complications Complications, difficulty swallowing

Subcutaneous emphysema: The fracture piece pierces the pharyngeal wall, and the gas can enter the subcutaneous tissue, causing extensive subcutaneous emphysema.

Symptoms of hyoid bone fractures Common symptoms dysphagia chest contusion vomiting bloody subcutaneous emphysema dyspnea edema severe pain

1. Laryngeal pain: The front part of the neck, the pharynx, especially the tongue, has a severe tingling sensation, and the pain is aggravated when speaking or swallowing.

2. Dysphagia: Due to the affected tongue activity or the fracture of the hyoid bone into the pharyngeal cavity, there is swallowing pain and difficulty swallowing.

3. Sonar and loss of voice: lighter voices, heavy voices.

4. Difficulty breathing: The fracture piece penetrates into the pharynx, the blood flows into the throat, the hematoma at the base of the tongue, the edema of the throat or the back of the tongue and the throat, and different degrees of dyspnea can occur.

5. Swelling of the neck: There is tenderness in the hyoid bone area, and the fracture piece and friction sound can be touched in the early stage.

6. Physical examination: see swelling and tenderness in the hyoid bone area, sometimes touching the rubbing sound of broken bones. If there is subcutaneous emphysema and vomiting blood stasis, the throat should be examined for fractures.

Examination of hyoid bone fracture

X-ray cervical lateral radiograph showed light-transition fracture line shadow, continuous interruption of hyoid bone cortex and dislocation of fracture piece. It is reported that 1/2 fracture line of hyoid bone fracture is located at the junction of the large angle of the hyoid bone and the hyoid bone. Another 1/2 of the fracture line is located in the large angle of the hyoid bone, due to the fissure of the muscle contraction, the fracture of the large angle of the hyoid bone.

Note: Before the age of 45, the large angle of the hyoid bone is separated from the hyoid bone. It should not be mistaken for the fracture line, the unconformed shadow of the small angle of the hyoid bone of the young man and the calcification of the ligament of the stem and lingual ligament of the proximal lingual bone. Or ossification, like fracture fragments, should pay attention to distinguish.

Diagnosis and diagnosis of hyoid bone fracture

Diagnostic criteria

1. History: There is a history of contusion in the neck, mandible or upper chest.

2. Clinical manifestations: severe pain in the front of the neck and throat, severe dysphagia or difficulty in breathing; examination revealed swelling of the hyoid bone area, tenderness, and sometimes touching the rubbing sound of broken bones.

3. X-ray inspection.
