Dr. Liu Weitao’s orthodontic case, Baotian

A 7-year-old boy and a half-year-old boy, designed and used the improved FrankelIII functional orthosis, using muscles and occlusion power to improve the anterior teeth in 5 months. For the part to be mastered, more practical and clinical experience is needed to sponsor early correction. The most important thing is to grasp the timing and choose the plan. Different bone types, different dental conditions, and different causes of ground cladding, the timing of treatment varies greatly, and the choice of aligners also has different considerations. The commonly used clinical methods are: anterior maxillary traction, reed cushion spring, continuous crown oblique guide, FrankelIII , 2*4 orthotics, etc. The orthodontist needs detailed examination, personalized plan and appliance design combined with the child’s situation. The following are some tips for the doctors. The following factors need to be considered during the design of the earth-encased appliance. 1. Maxillary retraction or mandibular protrusion is the Lord? 2. Is there any skew? 3. Are there any irregularities in width and height? 4. Can the jaw retreat? 5. Are there any bad habits? 6. Is there a family history? 7. At what stage of replacement? 8. Eruption of permanent teeth and development of tooth roots, etc. In addition, as mentioned before on Weibo, the nuances of the design may be the key to success, and doctors should pay attention to avoid the same. At the same time, we must pay attention to the growth and development of children, and adjust the braces at any time, not to restrict the growth and development #健康中国2030#

Factors that determine the width of both eyelids

The precise design positioning of the double eyelid line is only a small step before surgery, because the design line is only an important factor in determining the width of the double eyelid. In clinical practice, such a situation often occurs. The line design of the eyes on both sides is basically the same, but the width of the lines after the operation is different. Sometimes the design lines on the two sides are obviously different, but the width of the double eyelid line is basically the same. &nbsp. Next, I will analyze the factors that determine the width of the double eyelids. The factors of the skin suture position are often written in textbooks 6-8mm to explain the design width range of the double eyelid. In fact, there are many factors that determine the width of the double eyelid, and it is not as simple as drawing a line. The pre-operative design line is to determine the location of the stretched skin, which is very close to the width of the double eyelid. Within a certain range, the higher the design position, the wider the double eyelid fold line. &nbsp.&nbsp. 2. Factors of the levator muscle or meibomian suture position (including the levator muscle opening and closing factor) in addition to the design of the point of care, the muscle strength of the levator muscle also has a very important effect on the width of the double eyelid and folds. &nbsp. When the levator displacement is different, the width of the double eyelid line is also different. 1. When the normal muscle strength is open, a deep double eyelid fold is formed; when the levator muscle is weak, the mobility is poor, and the double eyelid line is shallow and wide. Patients with ptosis cannot form a deep double eyelid fold, which is the reason for the insufficient displacement. In other words, although the double eyelid fold is relatively wide, it appears to be inexplicable due to the low corneal exposure rate! &nbsp. Under normal muscle strength, even if the design line of the double eyelid is the same, if the position of the levator muscle or the eyelid plate is different, it may result in a different width of the double eyelid. three. The factor of skin peeling amount has a great influence on the width of double eyelid. Under the premise that the muscle strength is normal, the design line of the double eyelid is the same, and the position of the levator muscle or the eyelid plate is the same, the more loose the skin, the more the upper lip skin covers the lower lip skin after reflexion, the more the double eyelid fold line appears narrow. It can be seen that, within the limit and reasonable range, the greater the amount of peeling during double eyelid surgery, the wider the double eyelid width. &nbsp. Factors of the volume of the lower lip tissue&nbsp. The height difference of the eye is limited by the fold line of the double eyelid, the relative height of the incision upper lip (the area between the double eyelid line and the eyebrows) and the lower lip (the area between the double eyelid line and the eyelashes) . Generally, the upper lip should be higher than the lower lip: the upper lip is slightly thicker, forming a sense of high-land fold, and the lower lip is easily folded into the upper lip, forming a natural and beautiful double eyelid appearance. &nbsp. Factors of tightness of incision adhesion The more firmly the double eyelid incision is adhered, the firmer the site of suture and attachment point is. Whether the thread is buried or the double eyelid is cut, the tissue of the adhesion site will gradually relax and shift downward. That is, the position of the fixed point of the double eyelid suture is also moved downward, and the width of the double eyelid will be narrowed. The double-embedded thread is most likely to loosen because the scar is lightly adhered and the nylon thread is cut.

What are the signs of failure of double eyelid surgery?

In China, double eyelid is one of the most common cosmetic surgical treatment projects. With the continuous improvement of people’s aesthetic ability, the evaluation system is becoming more and more refined, which puts forward higher requirements on the shape, recovery speed and dynamic expressiveness of double eyelid. When someone repairs their eyelids three or five times, they strive for perfection without regret. What is double eyelid repair surgery? Double eyelid repair is to improve the double eyelid double eyelid line due to inborn or acquired double eyelid surgery by inborn or acquired surgery. The double eyelid line is not obvious, partially and completely disappeared. The double eyelid is too wide or too narrow, the arc is interrupted, the bilateral asymmetry, double Eyelid is too thick, scar hyperplasia, difficulty lifting the eyelid, poor eyelid closure and other problems existing in double eyelid. Improve and repair these problems to make the double eyelid look natural. What are the failures? 1. Inappropriate choice. Different double eyelid surgery has different indications. Both the operator and the recipient should be clear that not all single eyelids need double eyelid surgery, nor are all single eyelid people made double eyelid. Add beauty. People’s beauty is not entirely dependent on single eyelid or double eyelid. It is closely related to the coordination of the individual’s face shape, eyebrow shape, eye shape, ear shape, etc., and also has a certain relationship with the individual’s personality, temperament, expression, etc. . Some people have a single eyelid that is slender, bright, and harmoniously matches the facial features and face. It looks elegant and natural, and does not need double eyelid surgery. 2. Inappropriate preoperative morphological design, correct double eyelid line and its morphological design are the prerequisites to ensure the success of double eyelid beauty. Inadequate design or failure to adopt the correct design method will inevitably lead to problems such as high or low double eyelid lines, bilateral asymmetry, and poor double eyelid line morphology. The general principle of the design is that according to the patient’s face shape, blepharoplasty length, and nose bridge height, it is necessary to pay attention to its width, but also to consider its length, curvature, and the shape of the double eyelid to be formed after surgery. In addition, patients must actively participate in the design and obtain the consent of their families or third parties. 3. Improper choice of surgical style Improper choice of surgical style is another major cause of the poor cosmetic effect or failure of double eyelid. The selection of surgical methods should be based on the patient’s face shape, the scope of application of various surgical methods, and the surgeon’s habits and experience. It is impossible to use a single surgical method to solve all problems. Fourth, the operation of sparse double eyelid surgery is a fine, high-demand cosmetic surgery. The operator must have a serious and meticulous medical style and scientific attitude. In addition to conscientiously making all necessary preparations before the operation, strict aseptic operation must be performed during the operation, and the movement must be light and accurate, to avoid roughness and sloppyness. Only in this way can the success of the operation and the satisfaction of the postoperative effect be achieved.

Surgery case sharing

Preoperative problems: The beggars sharing today have loose upper eyelids, bilateral asymmetry, sunken sockets, and myopia cause the eyes to protrude. With the problem of the inner canthus, the distance between the brows and the eyes is far away, and the eyes feel deeper. Although he is young, he feels tired and old. Preoperative design: According to her situation, design a new double eyelid line along the upper eyelid. When closing the eyes, the double eyelid line is designed at the widest point 7mm away from the upper eyelid margin, and then a new inner canthus point is designed according to the ratio of the five eyes. Surgical procedure: After disinfection and draping, the double upper eyelid was subjected to local infiltration anesthesia. After the anesthesia takes effect. Double eyelid surgery was performed on the right side first. Cut the skin along the design line, and pay attention to protect the vascular network during the period. Remove a small amount of the anterior orbicularis oculi muscle of the meibomian plate, open the orbital septum, loosen the fiber strands in the anterior and posterior walls of the orbital septum, and improve the levator muscle conduction strength. The fat of the lateral orbital septum is released and fixed in the empty area of ​​the medial upper eyelid. Note that the patient is required to open and close the eyes, and when the internal fixation is completed, the skin is sutured intermittently. The remaining methods on the left are the same as on the right. Postoperative feedback: improve the depression through the release of the orbital septal fat, open the inner canthus to adjust the shape, although there is still swelling at 7 days after surgery, but the eyes are symmetrical and smooth, the proportions are harmonious, and the spirit is clear and young! Postoperative care: Do not rub the surgical area with your hands after surgery to avoid hematoma and infection. And pay attention to eye hygiene to avoid eye fatigue. Avoid shampooing within three days to prevent dirty water from flowing into the wound and keep the wound clean and dry. Eye makeup is prohibited for two weeks, and eye makeup can be changed after one month. Within one month after surgery, it is best to avoid drinking, smoking, and avoiding spicy food and seafood.

“Jia” words plastic surgery | Prejudgment design in rhinoplasty

Many friends will feel a little higher than their expected effect after rhinoplasty. In fact, this is the pre-judgment design of our pre-sprouting rhinoplasty. In order to prevent the nose tip from hanging after rhinoplasty or other indications, it will be The pre-operative design and intra-operative reserved space for underhang, generally wait for about 6 months to restore the effect you want. Why does the effect after rhinoplasty deviate from your expectations? On this issue, today we will talk about the pre-judgment design in the budding nose. Pre-judgment design Pre-judgment design is used in most plastic surgery operations. It generally refers to the “rectification” method implemented during surgery to ensure postoperative effects and other indications. &nbsp. Surgical options Many beauty seekers with traditional ear cartilage rhinoplasty will find that their nose hangs under the rhinoplasty for 1-2 years. Such a situation occurs because the prosthesis slides and moves, and there is support The support of the tip of the nose is not stable enough, and the supporting force is not enough, and the tip of the nose may also hang underneath. In addition, the autologous cartilage material used has been absorbed and retracted, sometimes accompanied by the problem of nostril exposure. At this time, our pre-judgment design in rhinoplasty is particularly important. Generally, I will design the surgical plan according to your skin extensibility, cartilage support and your nose in the preoperative diagnosis design. During the operation of budding nose, the tip of the nose will be made a few millimeters higher to give postoperative Restoration reserves space under suspension to prevent other indications such as under nose suspension after rhinoplasty recovery. &nbsp. The pre-judgment design of the recovery effect in the budding nose can achieve your expected effect in about 6 months after the operation. Most customers are satisfied with the effect after the thread removal and swelling after the operation. During the process of recovery The satisfaction level is also getting higher. Like the following feedback from the beauty seeker, the effect of rhinoplasty tends to be natural, which is also her favorite nose shape. After the rhinoplasty is completely restored, the nose shape is basically stable. In summary, the pre-judgment design is very suitable for people with short noses and sky noses, which can effectively avoid the problem of repairing and repairing the nose after rhinoplasty. More eye and nose plastic problems can be consulted by private letter.

What are the signs of double eyelid failure?

We all do double eyelids for the sake of good looks, but some of them are not as good as the previous eyes, but I do n’t know where the problem is, so there are many girls consulting, what kind of double eyelid is considered What failed? Here is an analysis of common clinical failures of double eyelids: 1. Incision scars. Because of incision infection, the incision edge is not well aligned, or the patient is scarred. 2. Double eyelids are too wide, too narrow, too long, too short, bilateral asymmetry. The reason is improper design, the design line is too wide, too narrow, too long, too short, bilateral asymmetry, not cut according to the design line when cutting. The design does not consider the patient’s own bilateral asymmetry. 3. Three eyelids form. Originally seen in the embedding method. The orbicularis oculi muscle was removed too much above the incision, causing the upper eyelid skin to adhere to the deep tissue to form a triple eyelid. Because the original double eyelid adhesive line is not separated, the original double eyelid line and the newly designed double eyelid line form a triple / multi-eyelid, etc. 4. The appearance is not beautiful. The patient’s eye fissure is short, forming double eyelids wide, and the eyes are rounded. The eyeball at the lower edge of the incision is not enough to remove the double eyelids. The shape of the double eyelid is unnatural. 5. Open eyes weak. Before surgery, the patient had mild ptosis or weak levator muscles. Excessive deep incision during operation lifted the levator muscle aponeurosis. Early hyperplasia of scars can be caused. 6. Both eyelid lines disappear. The reason is that the design line of the double eyelid is too low to form an internal double. The anterior orbicularis muscle of the meibomian is not removed enough to prevent the skin from adhering to the meibomian. It is not fixed to the aponeurosis of the meibomian when sutured. The premature thread removal is not strong enough. 7. Eyelid depression. Excessive fat removal of the orbital septum.

Good-looking nose consists of 4 key aesthetic angles-nose frontal angle

I have been engaged in the rhinoplasty professional field of the plastic surgery industry for more than 10 years. After undergoing thousands of large and small operations, there are thousands of beauty seekers who have been interviewed. So basically 90% of them will ask such questions. : What kind of nose do I make? Faced with this problem, I usually analyze each person’s facial features in detail, and then design a suitable nose shape based on the facial features and the foundation of the nose. My philosophy is: a good-looking nose must conform to scientific aesthetic standards, and at the same time make the nose and face harmonious and stand the test of time. So first of all, let ’s talk in stages: what kind of nose is beautiful? There are four key aesthetic angles to be met. Namely, the frontal angle of the nose, the corner of the nose, the corner of the nasal column-lobule, and the corner of the nose and lips. First of all, the importance of nose frontal angle. (1) Where is the nose frontal angle? Refers to the angle formed between the line between the eyebrow and the root of the nose and the back line of the nose. The simple understanding is that the angle formed by the transition between the forehead and the bridge of the nose is the frontal angle of the nose. Its aesthetic standards are generally around 130 ° to 135 °. The angle should be smaller for women and larger for men. At the same time, this angle is also related to race and region, and will be different. (2) How does the angle of the nose frontal angle affect the nose shape? 1. When the frontal angle of the nose is greater than the standard (130 ° -135 °), a common collapsed nose bridge will be formed; we can raise the nose bridge by injecting hyaluronic acid rhinoplasty or cushion prosthesis. 2. When the nose frontal angle is less than the standard (130 ° -135 °), it will form a iatrogenic nose; the solution is to take out the prosthesis, re-sculpt the appropriate height and curvature, and implant it into the bridge of the nose to form a natural Nose frontal angle. (3) For the nose frontal angle, how do I design the most suitable for you? First of all, beauty does not refer to a single point, but to coordinate with the surroundings. 1. The angle design of the nose frontal angle, do not look at the nose alone. We need to look at the fullness of the forehead, the height of the eyebrow arch, and the depression of the eye socket as a whole. With reference to these ratios, design the root of the nose at a suitable height, generally above the eye canthus and eyebrow arch ( Two eyebrows) Just a little below the line, the simple understanding is basically where you do the double eyelids, so that combined with the fullness of the forehead, a natural nose-frontal angle will be formed with the bridge of the nose. 2. The importance of preoperative evaluation design Before each operation, I will make a fine line design for the face and nose of the beauty seeker, and estimate a suitable value, so that I will control it more accurately during the operation . 3. The transition problem formed after sculpting and implantation of the prosthesis. That is to say, the highest point of our prosthesis is not the lowest point of the root of your nose. In fact, the prosthesis should be implanted at the lowest point of your nose, and then slightly higher, so that from top to bottom, it acts as a frontal nose transition, with a natural and beautiful arc, just like natural formation. general. The control in this area is mainly to test the doctor’s prosthesis carving technology and understanding of the nose. Generally, the transition of the nose area I make will be very important, and I must adjust it until I am satisfied during the operation. Judging from the postoperative feedback, the nose-frontal angle performance of the nose I did not dare to say that it is too perfect, but it is not outrageous, and it is usually very natural and coordinated. This fan who often sees me on Weibo should know everything. My case is a natural and beautiful arc in the frontal area of ​​the nose, which is not outrageously high! Finally, I would like to say this about the nose frontal angle in the 4 elements of good-looking nose. What questions do the fans have? & nbsp. & nbsp.
