Facial boils and carbuncles
Introduction
Introduction to facial facial paralysis Facial skin is one of the most abundant parts of human hair follicles and sebaceous glands, sweat glands, and exposed parts of the human body. It is exposed to external dust, dirt and bacteria, and it is easy to cause damage. Therefore, the acute suppuration of hair follicles and their attachments is caused. The inflammation is called furuncle, and its lesion is confined to the superficial tissue of the skin. Adjacent to most hair follicles and their attachments, acute suppurative inflammation is called carbencle. When the lesions fluctuate and the deep interstitial tissues of the skin, the superficial fascia spreads to the subcutaneous fat layer, causing a wide range of inflammation. Infiltration or tissue necrosis. basic knowledge Sickness ratio: 0.1% Susceptible people: no special people Mode of infection: non-infectious Complications: phlebitis, sepsis, sepsis
Cause
Facial paralysis
The pathogen of facial paralysis is mainly Staphylococcus aureus. Normal hair follicles and their attached bacteria often exist, but only when local inducement or systemic resistance declines, bacteria begin to cause inflammation, and local factors are mainly skin. Uncleanness, or repair of facial damage caused by various reasons can be an inducement; in patients with systemic failure, suffering from wasting disease or diabetes, it is also prone to paralysis.
Prevention
Facial spasm prevention
The key to prevent this disease is to pay attention to the cleansing of the facial skin, to prevent bacterial invasion, avoid scratching or squeezing, and strictly prohibit the incision and drainage, the patient should remember.
Complication
Facial paralysis complications Complications, phlebitis, sepsis, sepsis
Facial spasm is most likely to occur in oral and maxillofacial infections due to: the pathogenic bacteria of the cockroach are more toxic; the veins in the "dangerous triangle" of the upper lip and nose are often without valves; The physiological movements of the muscles and lips are easily caused by factors such as the spread of infection.
When phlebitis and thrombosis occur in the invading facial vein, venous return is blocked, and there may be extensive edema of the face, pain, and infection may be retrograde along the vein without valvular vein, causing thrombotic phlebitis of the cavernous sinus, edema of the affected eyelid, and prominent eyeball. Increased intraocular pressure, limited movement, loss of vision, photophobia, tears, and sub-conjunctival edema or blood stasis, high body heat, headache, until a conscious coma, if meningitis, brain abscess occurs at the same time, there is severe headache, nausea, vomiting, Item rigidity, high blood pressure, deep breathing, convulsions, coma and other meningeal irritation, signs of intracranial hypertension and intracranial space-occupying lesions, bacteria with blood circulation, can cause sepsis or sepsis, high fever, (often in 39 ° C or more) is a type of retention or relaxation, the patient is mentally irritable, paralyzed or indifferent, slow-responding, lethargy, and even coma, the skin has bleeding points or small pus, the total number of white blood cells and the proportion of neutrophils are significantly increased; In case of toxic shock, there is a drop in blood pressure and a fine pulse. If not treated promptly and correctly, it can lead to death. In sepsis fashion can be Now vital organs (such as liver, lung, etc.) and metastatic abscess trunk, limbs.
Symptom
Facial paralysis symptoms common symptoms cellulitis hyperthermia shock lymph node enlargement toxemia tissue necrosis
At the beginning of the sputum, red, swollen, painful and indurated knots appeared on the skin, and the cones were bulged and tender. Then there was a yellow-white pus on the hard-topped top. The surrounding was a red hard disk. The patient felt itchy, burning and jumping. After the pus is ruptured, the pain is relieved after a little pus is removed, or a pus is formed at the top of the pus, and the puncture is separated from the surrounding tissue. The inflammation gradually subsides, and the wound heals itself. In addition to the swelling of the lymph node in the drainage area, the general No obvious systemic symptoms, if not handled properly, such as random scratching or squeezing pus, hot compress, drug burning corrosion and improper incision, etc., can promote the spread of inflammation, located in the upper and lower lip, the nose, Because it is located in the "dangerous triangle" of the face, the infection can suddenly deteriorate, local redness, swelling, pain range, accompanied by cellulitis or eruption into sputum, even with cavernous sinus thrombophlebitis, sepsis or septicemia disease.
It occurs in the lips (lips), the upper lip is more than the lower lip, more men than women, the extent of infection and the depth of tissue necrosis are more serious than severe pain, when most hair follicles, sebaceous glands and surrounding tissues occur In acute inflammation and necrosis, a rapidly expanding purple-red inflammatory infiltrating mass can be formed. The infection can affect the subcutaneous fascia and muscle tissue. The initial surrounding tissue is also necrotic. After the necrotic tissue is dissolved and discharged, most of the honeycomb cavity can be formed. Subsequently, the skin, mucosa or subcutaneous tissue between the cavities can also be necrotic, resulting in the upper layer of the entire sputum lesion area is purple-red, and the tissue around and deep in the sputum is invasive edema.
The patients with cleft lip are extremely swollen in the lips, pain, restricted mouth and eating, speech difficulties, local lymphadenopathy, tenderness, symptoms of systemic poisoning, such as chills, fever, headache, loss of appetite, white blood cell count and neutral Increased white blood cell ratio, lip palsy is more likely to be associated with intracranial cavernous sinus phlebitis, sepsis, sepsis and toxic shock and water and electrolyte disorders, resulting in higher mortality.
Examine
Examination of facial paralysis
Take pus from the head of the pus for bacterial culture and drug sensitivity test for correct selection of antibiotics. Those suspected of having sepsis should be repeatedly cultured for blood bacteria, and the drug should be selected according to the results.
Diagnosis
Diagnosis of facial paralysis
Should pay attention to the identification of sputum, facial acne, head lice and so on.
There are systemic symptoms such as aversion to cold and fever, thirst, and facial acne usually occur in the lips, nose, eyebrows, and sputum. The local part begins as a pus, and the lumps are hard and deep, such as the shape of nails, or hemp or itching, followed by Red and swollen, can develop into a number of pus, burning pain, there are head lice also between the skin, from the beginning there is a miliary pus, easy to spread around the rot.
