Recently, I have been asked this question by a lot of patients in my clinic. Due to their ethnicity, many oriental people have excess skin in the inner canthus area, making the eye fissure shorter. Even if such patients have double eyelid surgery, the heavy lid line is short and does not reach the head due to the obstruction of the inner canthus, so the eyes do not look spiritual. Nowadays, the beauty propaganda also talks a lot about double eyelids and open eye corners, so it gives people the impression that it is necessary to do double eyelids and open eye corners, in fact, there is a misunderstanding here, I will talk about what kind of people need to open eye corners and what are the advantages and disadvantages of opening eye corners. After opening the corner of the eye attention. A, what kind of people need to open the eye angle Open eye angle must be the existence of the inner canthus, otherwise do not force open the eye angle. Because of the difference in ethnicity, oriental people (Chinese, Japanese, Korean, Korean, Mongolian, Vietnamese, etc.) have a different starting point of the orbicularis oculi muscle in the inner canthus, which is located outside and below the inner canthus point, so that the muscle and the surface skin form a skin curtain blocking the inner canthus point. For such people, it is important to surgically incise the medial canthus and interrupt the orbicularis oculi muscle at the medial canthus. Some people use the buried wire method, which does not correct the medial canthus. In ancient China, the proportion of facial features was noticed and the “three stops and five eyes” were proposed, i.e., the distance between the inner canthus of the two eyes is equal to the distance from the inner canthus to the outer canthus of one eye, so that the proportion is appropriate and looks beautiful. Therefore, patients who have a wide distance between the inner canthus of the eyes can achieve a beautiful ratio by opening the corner of the eye. Some people think that an open eye angle must be more beautiful than an open eye angle, and even the larger the eye angle, the more beautiful it is. This statement is incorrect, in fact, the eyes are beautiful or not depending on the width, curvature and length of the eyelid, one of the most important is whether it matches your face shape. This is why double eyelids are more individualized, which is important for the surgeon when designing. Not all oriental people have inner canthus, and therefore not everyone needs an eye opening. Some people open their eyes too wide, causing the eyelid distance to be too short, which is also unsightly and is known as “cross-eyed”. The advantages and disadvantages of opening the corner of the eye The advantage of opening the corner of the eye is that the eye fissure is lengthened, the eyelid becomes larger, and the eye looks spiritual. The disadvantage is that some people will have scarring at the corners of their eyes, especially patients with scarring. These scars gradually worsen in the first 2 weeks after surgery, with symptoms such as redness, itchiness and hardness of the incision, which usually gradually improve after 3 months. During this recovery period, care should be taken not to drink alcohol, eat less spicy and stimulating food, less exposure to overheated environment including bathing, and you can use some local ointment to prevent scar proliferation. Therefore, you should be cautious about opening your eyes, and reduce the blindness of following the trend, the open is open.
