Introduction

Cracked嘴角 from yawning may be caused by excessively dry skin, malnutrition, angular cheilitis, or other reasons, and requires targeted treatment. Dry weather, using overly hot water when washing the face, or frequently wiping the mouth with tissues can all lead to dryness of the skin around the lips, making the skin at the corners of the mouth thin and prone to cracking. Applying lip balm or moisturizer can help.

Cracked mouth corners when yawning may be caused by excessively dry skin, malnutrition, angular cheilitis, or other reasons, requiring targeted treatment. The specific analysis is as follows:

1. Excessively Dry Skin

Dry weather, using excessively hot water when washing the face, and frequently wiping the mouth with tissues can all lead to dryness of the skin around the lips. This makes the skin at the corners of the mouth thin and prone to cracking. Patients can apply lip balm or moisturizing cream to keep the skin around the lips hydrated.

2. Malnutrition

Deficiencies in nutrients such as vitamin B, iron, and zinc can weaken the skin around the lips, making it more susceptible to cracking. Patients should maintain a balanced diet, ensure adequate intake of all types of food, and avoid picky or selective eating habits.

3. Angular Cheilitis

Angular cheilitis refers to inflammation of the skin at the corners of the mouth. Inflammatory secretions irritate the surrounding area, causing redness, swelling, pain, and cracking. Under a doctor's guidance, patients may use antibiotic ointments such as chlortetracycline ointment or erythromycin ointment for treatment.

Besides the above causes, cracked mouth corners could also result from oral ulcers, cheilitis, or herpes simplex at the mouth corners. It is important to properly care for the affected area. If symptoms persist or worsen, medical consultation at a hospital is recommended.
