What Causes Tingling Lips?

The lips are made up of skin, orbicularis oris and mucous membranes. The free edges of the upper and lower lips together form a cleft, and the two ends of the cleft are called the mouth angle.

Lips

There is a shallow ditch on the upper midline of the upper lip surface called Renzhong. Among them, the middle point of the upper third is the acupuncture point. Clinical acupuncture can be used to rescue comatose patients. There is a shallow groove outside the upper lip, called the nasolabial sulcus.

First, lips and aesthetics

Lips are functional organs such as language, swallowing, and chewing. They also have the function of expressing emotions and are one of the important image organs of the face. In recent years, people pay more and more attention to the aesthetic role of lips. From an aesthetic point of view, there is no doubt that the shape of lips has a very important role. People often pay attention to the beauty of eyes and nose, but ignore the beauty of lips, teeth, and teeth that can reflect a person's health. Facial features require a harmonious correspondence to form beauty. The shape of the lips, the degree of mandible development, and the shape of the teeth all affect the overall beauty of the face.

Structure of lips

The lip is located directly below the face and is one of the important organs for chewing and speech. It is also one of the important factors that make up the beauty of the face, which can produce a compelling and rich expression. Medically, the scope of the lips includes the upper and lower lips and facial tissues surrounding the cleft lip, up to the bottom line of the nostril, down to the labial sulcus, and both sides to the nasolabial sulcus.

Lips are divided into upper and lower lips, and there is only one horizontal seam when they are closed together, that is, cracked mouth. The two ends of the cleft lip are called the mouth angle. The lips are mainly composed of skin, orbicularis oris, connective tissue and mucous membranes. There is a longitudinal groove in the middle of the upper lip. It is said that among people, this is a unique structure of human beings, and it is also a necessary factor for the beauty of the upper lip. The upper and lower lips can be divided into three parts: one is white lips; the other is red lips; the third is the mucosa.

Third, lips shape

1. The height of the upper lip skin is generally divided into three categories: the upper lip is short and the length of the upper lip is less than 12 mm; the middle is 12 to 19 mm; the upper lip is longer: the upper lip is longer than 19 mm.

2. The side view of the lips can be divided into three types according to the degree of lip protrusion: convex lips, with a prominent protrusion on the upper lip; positive lips, which appear to be generally upright; lip constriction, which means that the lips are retracted.

3. Thick lips and thin lips. The thickness of the lips refers to the thickness of the upper and lower red lips when the mouth is gently closed. The thickness of the upper and lower lips is not exactly the same. The lower lip is usually thicker than the upper lip. There is also a certain relationship between the thickness of the lips and the shape of the nose.

4, the width of the cleft can be divided into three types, the width of the cleft is less than 35 mm, is a narrow type; the width of the middle cleft is between 36-50 mm; the cleft is greater than 50 mm, commonly known as the big mouth.

Fourth, what aspects affect the perfection of lips shape?

1. The morphology of the upper and lower lips is abnormal,

2. Abnormal lip support structure, mainly caused by abnormal alveolar bone and teeth (column).

3. The lips and teeth and jaw tissue are inconsistent with other facial organs (eyes, nose, palate, etc.)

4. Deformities caused by various diseases (tumor, trauma, etc.)

Five, dental aesthetic standards

1. The texture of the teeth is hard, neatly arranged, suitable size, natural shape, normal position and growth direction.

2, white color, slightly yellowish.

3. The occlusion relationship is normal, with functions such as chewing and assisting in swallowing.

4. Good support effect, maintain the normal shape of lips and cheeks, make the face look younger, fuller and more coordinated.

What are the common abnormal mouth shapes?

The more common problems among the visiting patients are as follows:

Big mouth

The main manifestations are large cleft lips, protruded lips, teeth and gums exposed when speaking, which makes people feel more serious and even poor oral hygiene. The formation factors are mainly caused by bad habits in the genetic and developmental process. Most cases can achieve the purpose of corrective beauty through simple surgery, and some severe cases can also obtain satisfactory cosmetic results through accurate design and surgery.

2. Crooked mouth (partial jaw)

It mainly manifests that the midline of lips, teeth, and jaw are not consistent with the midline of the face, the left and right faces are asymmetric, and the corners of the mouth are skewed and inconsistent when speaking, which makes people feel imbalanced. The formation factors are mainly caused by diseases and bad habits during development. In most cases, satisfactory correction and cosmetic results can be obtained through accurate measurement, design and surgery.

3. "Bird beak" (maxillary and maxillary protrusion)

It refers to the anterior protrusion of the upper and lower jaw lips, which causes the appearance of a "bird's beak", often accompanied by the turning of the lips and the exposed gums, which are inconsistent with other tissues and organs on the face. The cause is mainly caused by bad habits in the process of disease, inheritance and development. In most cases, the purpose of cosmetic correction can be achieved through surgery.

4. Earth Day (Anti-jaw)

It mainly manifests that the mandible is too long, and the mandibular anterior teeth are located outside of the maxillary anterior teeth at rest, which not only affects the temporomandibular joint movement, occlusal relationship and function, but also the face is too long and the proportion of facial structure is not coordinated. The cause is mainly caused by bad habits in the process of disease, inheritance and development. Can be corrected by surgery.

5, exposed gums,

The main manifestation is exposed gums. The front gums are exposed when talking, smiling, or even at rest. It affects not only gum health but also your own image and the effect of communication with others. The main causes are genetic and bad habits. Can be treated surgically.

6.Cleft lip

Cleft lip is a common and typical congenital malformation, which is mainly manifested by a crack in the lips after birth. This deformity seriously affects the facial shape due to the destruction of the lip structure. It can be divided into I degree, II degree, and III degree according to the size of the crack. Most patients have alveolar palate. The cause is that during the embryonic development period, the protrusions are not well fused, causing cleft lip. The treatment is surgery.

7. Aging of the nasolabial folds

Nasolabial sulcus is a groove at the junction of nose, face, and lips. Due to the unsynchronized activity for a long time, this part often forms a deep and obvious groove, making people look old. Currently, there are non-surgical methods for cosmetic treatment.

8.Other lip shapes are abnormal

Common morphological abnormalities include lip eversion, heavy lips, thick lips, thin lips, and uneven red lips, which affect the overall image, most of which are due to infection, trauma, genetics and bad habits. Correction can be achieved through simple cosmetic surgery.

Seven, what are the contraindications to plastic surgery of lips, teeth and jaw?

1.Myasthenia gravis

2.Patients with neuromuscular diseases

3. Allergies

4, pregnancy and lactation

5. People who have a history of drinking within a week (including beer)

6. Those who have taken aspirin or other antipyretic and analgesics within two weeks

7. Those who use aminoglycoside antibiotics (such as gentamicin streptomycin, etc.)

8, poor mental control ability

9, can not reduce the facial expression muscles frequently active people.

The upper and lower lips can be divided into 3 parts:

skin (also called white lips);

The red lips are the red lips that are seen on the front when the lips are lightly closed. The red lips are very thin, without cuticles and pigments, so they can penetrate the blood color in the blood vessels to form red lips.

The mucosal part is part of the oral mucosa on the inside of the lips.

The length in humans usually reflects the height of the exit lip skin, which does not include red lips. Generally divided into 3 categories:

Lower lip, upper lip height is less than 12mm;

Medium lips, 12-19mm;

High lip, upper lip is usually higher than 19mm.

People whose skin on the upper lip is less than 10-12mm have less beautiful lips.

The lateral view of the upper lip skin can be divided into 3 categories according to the degree of lip protrusion:

convex lip, the skin of the upper lip is prominently protruding;

Positive lips, showing the skin of the upper lip is generally upright;

Lip constriction;

Yellow people, such as Asians, have mostly positive lips. Blacks, like Africans, have raised lips. White people, such as those in Europe and the United States, often have positive or reduced lips.

Lip thickness refers to the thickness of the upper and lower red lips when the mouth is gently closed. Some people are divided into 4 categories based on the average thickness of the upper and lower lips:

Small thin lips with a thickness below 4mm;

Medium lips with a thickness of 5mm;

thicker lip, the thickness is 9-12mm;

Thick convex lip, the thickness is greater than 12mm.

Because the thickness of the upper and lower lip is not exactly the same, and the lower lip is usually thicker than the upper lip. Therefore, Japanese aesthetic medicine experts believe that the thickness of the upper and lower lips should be observed separately. They believe that the standard value of female lips is: 8.2mm on the upper red lip, 9.1mm on the lower red lip, and men are slightly thicker than women by 2-3mm. The lip thickness changes with age obviously, after 25 years old, especially after 40 years old, the lip thickness can be obviously thinned. Therefore, some people say that "the thinner the lips, the more able to speak." This has no scientific basis. In addition, the thickness of the lips varies considerably in race. Africans have the thickest lips, while northern Europeans and North Asians have thinner lips.

At the same time, there is a certain relationship between the thickness of the lips and the shape of the nose. Generally thin lips or medium thick lips are often associated with narrow nose shapes, while those with thick lips have broad nose shapes. In addition, according to the width of the cleft, it can also be divided into 3 types:

Cherry small mouth, the width of the cleft is less than 35mm, it is a narrow type, which is a more beautiful mouth shape for women;

The width of the middle cleft is between 36-50mm, and most men and women have this type of cleft;

Wide clefts are often larger than 50mm. They are commonly called big mouths. They are not beautiful and sometimes require cosmetic surgery.
