Half a month ago, Dongdong (pseudonym), a 13-year-old boy living in Xiangtan County, Hunan Province, found a "acne" in his nose. He felt uncomfortable and couldn't help but use his hands to pick it off, trying to squeeze out the acne. Afterwards, Dongdong's left lower eyelid and surrounding skin became a little red. He didn't care much at the time and thought he would be better in two days. As time goes by, the skin around the eyes not only did not improve, but became redder, and even the entire left eye was swollen. There were also a lot of yellow secretions, which made the person have a high fever of 39.7 degrees and had a headache. This made my mother very anxious and quickly sent Dongdong to the local hospital.
The doctor found that Dongdong was squeezing the acne that squeezed the "dangerous triangle area", which caused cellulitis and suppurative meningitis . Subsequently, Dongdong was transferred to Hunan Children's Hospital for treatment.
"H Staphylococcus aureus was found in Dongdong's blood." Chen Bo, chief physician of the Department of Neurology at Hunan Children's Hospital, introduced that when Dongdong was admitted, the infection index was very high and his face was swollen. After active treatment, Dongdong's high fever has been controlled, facial swelling has gradually subsided, and the condition is improving.
"This place is like guarding a weak gate, which is easy to be broken." Chen Bo said that the "dangerous triangle area" refers to a triangle area composed of the corners of the mouth on both sides to the base of the nose. The reason why the "dangerous triangle area" is dangerous is because of the particularity of this area.
The first special feature is that the superficial facial veins in this area include the anterior vein and superficial temporal vein, which are connected to the intracranial cavernous sinus.
The second special feature is that the valves in the front vein are dysplasia, few and weak, and incompletely closed. The biggest function of venous valve is to play the role of a one-way "valve" to ensure that blood flows in the venous blood vessels towards the heart. Due to incomplete closure, the blood can usually be reversed under muscle contraction.
Therefore, when inflammation occurs in the "hazardous triangle area", it is prone to reverse flow to the superior ocular vein. Once complications occur, symptoms such as eyelid edema, or laryngeal stasis, protrusion of the eyeball, restricted abduction, ptosis and even visual impairment may usually occur. Inflammation can also spread to the eyes and surrounding tissues, and chills, fever, headaches, etc. may occur throughout the body. In severe cases, sepsis and toxemia may even occur. venous sinus may also enter the skull, causing severe cavernous sinus thrombosis or severe cerebral abscess , which is life-threatening.
Chen Bo reminds that teenagers and children who are in adolescence have relatively high hormone levels, and the "dangerous triangle" has many sebaceous glands and sweat glands, which are prone to blockage of hair follicles, inflammation, acne or boils. When acne or boils appear in dangerous triangle areas, remember not to squeeze and keep the local clean. If necessary, treatment and care can be carried out under the guidance of professional medical staff.
