Introduction

Introduction Radiation wrinkles outward from the corner of the mouth are caused by diseases such as angular cheilitis, and a clinical symptom of radioactive wrinkles that is clearly visible at the corners of the mouth. The keratitis is commonly known as the "rotten corner", which is characterized by flushing, blistering, splitting, erosion, crusting, and scaling. The patient's mouth is prone to bleeding, and even eating and talking are affected. The predisposing factor of keratitis is the cold and dry climate, which will cause the skin mucosa around the lips and mouth to be chapped. The surrounding bacteria will cause infection and cause angular keratitis. When the lips are dry, people often habitually use the tongue to lick. It is easy to chapped the mouth; if the vitamins ingested from the diet are reduced, the deficiency of B vitamins in the body will lead to the deficiency of vitamin B deficiency.

Cause

Cause

Mechanical factor

The position of the teeth is not suitable, causing the upper lip to be pressed against the lower lip, and the corners of the mouth are wrinkled, where the mucosa is often in the impregnation.

Lack of nutrition

Riboflavin deficiency, accompanied by strawberry-like tongue and scrotum itching. Excessive labor, excessive physical exertion or physical weakness, malnutrition, iron, insufficient protein supply and multiple vitamin deficiency: such as niacin, vitamin B6, etc. can cause the disease. Infection: Most of the pathogens are low-toxic pyogenic bacteria or Candida albicans, which are more common in children. Some skin diseases, such as: atopic dermatitis, seborrheic dermatitis, abnormality combined with oral dermatitis. The inflow of the sputum can cause the disease; biting fingers, biting the pen, etc. can also cause the disease.

Oral X-ray examination of oral endoscope

The lips are dry, and the mouth may be immersed, wet, smashed, chapped, and consciously have a burning sensation. Diagnosis can be based on clinical manifestations.

Initially the lips are dry, erythema, edema, exudate, and scarring at the corners of the mouth. When it is transferred to chronic skin, the skin of the local mucous membrane is moist, chapped, and rough desquamation occurs. If malnutrition, anemia, riboflavin deficiency may be associated with oral, lingual and genital mucosal damage, such as smooth tongue, scrotal skin redness and corresponding systemic symptoms. Multiple bilateral symmetry, can also be unilateral onset. Consciously have a burning sensation. In children with malnutrition, pustules can appear in and around the mouth and are often associated with infection with pyogenic bacteria.

Diagnosis

Differential diagnosis

Differential diagnosis of radioactive wrinkles from the outside of the mouth:

Malnourished keratitis

Malnutrition keratitis often occurs in people with nutritional deficiencies and vitamin B deficiency, and the most common form of keratitis caused by vitamin B deficiency. The performance of the bilateral mouth is wet white, erosive or ulcerated, with transverse sulcus, and even from the mouth to the oral mucosa or perioral skin, the sulcus is shallow, the length is not the same, the pain is not obvious, the mouth is often painful when stimulated . Often accompanied by dry lips, cracks, occasional scales, slightly swollen lips. The back of the tongue is smooth, the filamentous nipple is atrophied, the edema of the edema is thick and the nipple is scattered, and the tongue edge often has scallops. Also often accompanied by cheilitis, glossitis. Treatment should strengthen nutrition, supplement vitamin B

Coccidiosis

Cochlear keratitis is an angular keratitis caused by streptococcal and staphylococcal infections. More common in elderly patients without teeth. It is characterized by bilateral white lips, erosion or ulceration, transverse cracks, and purulent, bleeding, and crusting. The treatment should be partially cleaned, rubbed with antibiotics (such as erythromycin ointment), and oral broad-spectrum antibiotics can be taken orally with penicillin V potassium tablets, sulfa drugs, spiramycin, etc.

Fungal angular keratitis

Fungal angular keratitis is an angular keratitis caused by infection with fungi (mainly Candida albicans). The performance of the bilateral mouth is wet white and white is more obvious, there are erosions or ulcers, there are transverse cracks, there may be suppuration, hemorrhage, crusting, often accompanied by cheilitis and lip erosion. Candida mycelia can be seen by PAS staining. The treatment should be partially cleaned with nystatin, dried, and then partially coated with mycotoxin, clotrimazole, miconazole, and the like.
