Botulinum injection has the effect of relieving and relaxing the muscle tension at the injection site . By injecting into the muscles around the eyes, it can be expected to have the effect of adjusting the impression of the eyes in the field of cosmetology, and it is also possible to improve strabismus and blepharospasm in general medicine.
However, the amount and site of injection of the preparation will vary depending on the type of treatment you receive. In addition, botulinum injection is considered to be a procedure that can be easily received because there is almost no downtime, but there is a risk that an incorrect injection amount or injection site will cause an unnatural expression .
Therefore, in order to receive the treatment with more peace of mind, it is important to know in advance the type of eye treatment using botulinum injection that can be received in cosmetology and general medicine, and the appropriate injection amount and injection site . ..
Table of contents
The component of the drug used in botulinum injection is that it decomposes toxins from Clostridium botulinum, which is also the causative agent of food poisoning, and extracts botulinum toxin, which is a type of protein. Since the toxic components that are harmful to the human body have been removed, there is no effect on the human body .
Botulinum injection is a procedure that uses a needle to inject a drug into the muscle. When botulinum toxin acts at the junction between nerves and muscles, it suppresses the action of acetylcholine, a neurotransmitter released from nerves to muscles, and can relieve muscle tension.
There are seven types of botulinum toxin, types A to G, but before the toxin is decomposed, four types, type A, type B, type E, and type F, are pathogenic to the human body. When ingested, it has the characteristic of causing symptoms such as fever and vomiting. Formulations used in the medical field after breaking down toxins are types A and B.
Botulinum injection in aesthetic medicine is mainly used as a treatment that relaxes muscle tension and improves facial expression wrinkles, ella and calf tension. On the other hand, in the field of general medical care such as ophthalmology, it can also be used as a treatment for blepharospasm (blepharospasm) in which one line of sight does not face the object or the eyelids convulsions regardless of their own intentions. It is used.
The botulinum injection formulation is in a bottle, and the amount is expressed in "units" rather than ml or cc. There are 50 unit formulation and 100 unit formulation in the dosage of the formulation, and since the formulation is in powder form, it is diluted with physiological saline and injected when using it in the procedure.
The type and amount of preparation used depends on the injection site, and the concentration of botulinum preparation changes depending on the amount of saline used for dilution as follows. The greater the amount of saline used for dilution, the lower the concentration of botulinum preparation infused during the actual procedure .
|Amount of saline used for dilution||Botulinum concentration after dilution (per injection volume 0.1 ml)|
|For 50 unit formulation||For 100 unit formulation|
|1.25ml||4.0 units||8.0 units|
|2.0ml||2.5 units||5.0 units|
|2.5ml||2.0 units||4.0 units|
|4.0ml||1.25 units||2.5 units|
|5.0ml||1.0 unit||2.0 units|
When botulinum infusion is repeated, the action of botulinum toxin may be attenuated by the production of neutralizing antibodies in the body that try to reduce protein and neutralize the activity. Therefore, when re-injecting botulinum, it is common to wait 3 to 4 months from the previous injection regardless of the site and symptoms .
In the botulinum injection treatment around the eyes , the preparation is injected into the facial muscle called the orbicularis oculi muscle (Ganrinkin), which surrounds the eyes in a circle.
Injection needles used for blood sampling, intravenous drip, vaccination, etc. are generally used for injection of preparations, and although there are individual differences, it is said that you will feel a tingling pain when inserting the injection needle . Some medical institutions can use anesthetic cream or laughing anesthesia if you wish, so if you are not good at pain, please contact the medical institution before receiving the treatment.
The main types of wrinkles are wrinkles caused by sagging skin, crepe wrinkles caused by dryness and ultraviolet rays, and facial wrinkles caused by habit of facial muscles. In most cases, wrinkles on the outer corners of the eyes are classified as facial expression wrinkles .
By repeatedly changing facial expressions such as laughing and getting angry and using facial muscles on a daily basis for a long period of time, the tense facial muscles cannot be restored, and wrinkles are gradually fixed, causing facial wrinkles at the corners of the eyes. ..
Wrinkles can be reduced by injecting botulinum multiple times at different positions on the orbicularis oculi muscles on the outer corners of the eyes to relieve tension and relax the orbicularis oculi muscles. The duration of botulinum injection is 3 to 4 months, so if you want to maintain the effect, you need to receive regular treatment.
By injecting botulinum into the orbicularis oculi muscle in the lower eyelid, the strength to support the lower eyelid is weakened. By relaxing the muscles and lowering the position of the lower eyelids, you can make your eyes look bigger and lead to the eyes that tend to have sagging eyes .
There are three injection sites for sagging eye formation by botulinum injection, and the expected effects are different for each.
|Position of the orbicularis oculi muscle to inject||Expected effect|
|Lower eyelid on the outer corner of the eye||Emphasis on sagging eyes|
|Center of lower eyelid||Eyes with a tight impression|
|Lower eyelid on the outer corner of the eye + center of lower eyelid||Eyes with a crisp, sagging eye that emphasizes the vertical width of the eyes|
The botulinum injection has no lasting effect on the formation of sagging eyes and lasts for about 3-4 months, so continuous treatment is required to maintain the sagging eye line .
As a method of forming sagging eyes that can be expected to have a lasting effect, an incision is made in the outer corner of the eye to increase the width of the eye, and an incision is made in the conjunctival side of the lower eyelid to lower the position of the lower eyelid. There is a method called "Kaganken Kaseijutsu", also known as "Glamorous Line".
The treatment time for botulinum injection is as short as 5 to 20 minutes without anesthesia and 20 to 40 minutes with anesthesia, but if the injection amount or injection site is incorrect, the facial expression will look unnatural. It may cause eyebrow drooping or lowering the position of the eyebrows .
In addition, temporary swelling, redness, and internal bleeding may occur at the injection site of botulinum, but in most cases it will subside for 2 days to 1 week.
There is almost no downtime, but you may feel a slight bulge in your eyes immediately after injecting the formulation due to the effects of saline . However, saline is absorbed into the body in about 1 to 2 hours, so it tends to settle in a short time.
The treatment of wrinkles on the outer corners of the eyes and the formation of sagging eyes by botulinum injection are free medical treatments that are not covered by insurance, so you will be responsible for all costs.
Since the fee for free medical treatment can be decided by each medical institution, the fee set for the same treatment differs depending on the medical institution.
|Type of treatment||Wrinkle treatment at the corners of the eyes||Sauce eye formation|
|Fee||Both eyes: 16,000 yen to 50,000 yen||Both eyes: 18,000 yen-75,900 yen|
|Injection amount||Both eyes: 12 to 24 units||Both eyes: 8 to 16 units|
|Injection site||Orbicularis oculi muscle around the outer corner of the eye||Orbicularis oculi muscle around the lower eyelid|
Botulinum injection is a treatment method originally used in general medical care such as ophthalmology for the purpose of improving strabismus and blepharospasm as follows . Later, it was approved by the Ministry of Health, Labor and Welfare that it was effective in improving wrinkles, so it was also applied in the field of cosmetology.
Blepharospasm is an eye disease in which the orbicularis oculi muscle contracts regardless of one's will and the eyelids cramp. Eyes may not open when unnecessary blinking increases or symptoms worsen.
Self-check items for blepharospasm include the following symptoms.
It is said that the reason why the contraction of the orbicularis oculi muscle causes eyelid spasm is due to abnormalities in transmitters secreted from nerves . Therefore, by injecting botulinum, which works to block nerve transmission, it is possible to relieve muscle tension and improve blepharospasm .
Strabismus is a symptom in which both eyes cannot look in the same direction and one eye does not look at the object regardless of the person's intention.
The cause of communal strabismus that occurs in childhood is often unknown, but there are also cases of strabismus due to heredity or paralysis of muscles that move nerves and eyes (line of sight). .. Acquired strabismus after adulthood is called paralytic strabismus caused by head trauma or muscle abnormalities / paralysis.
There are four types of strabismus: exotropia, esotropia, hypertropia, and strabismus . As shown below, the part of the muscle to which botulinum is injected differs depending on the state of strabismus, but in any case, the action of botulinum toxin temporarily paralyzes the muscles around the eyeball to normalize the line of sight. You can expect the effect of keeping it in position .
|Classification of strabismus||How to get out of sight||Injection site|
|Exotropia||Come off to the outside||Lateral rectus muscle (outside the eyeball)|
|Esotropia||Come off inward||Medial rectus muscle (inside the eyeball)|
|Hypertropia / strabismus||It comes off to the upper and lower sides||Superior rectus muscle / inferior rectus muscle (upper and lower eyeballs)|
Blepharospasm caused by botulinum injection may cause eyelid insufficiency, which makes it difficult to close the eyelids due to the side effects of weakening the muscles around the eyes, which may lead to dry eyes and increased tear production . .. In addition, there are risks and side effects such as eyelid insufficiency that makes it difficult to open the eyelids, diplopia in which objects appear to overlap, and subcutaneous bleeding at the needle injection site .
Over the years, the effects of botulinum injections diminish, and the side effects mentioned above tend to subside as the eyelids return to their original state .
The treatment of blepharospasm and strabismus by botulinum injection is covered by insurance because it is a procedure approved by the Ministry of Health, Labor and Welfare .
|Type of treatment||Blepharospasm||Squint|
|Injection amount|| One eye: 1.25 units to 2.5 units x 6 parts|
Total monthly injection up to 45 units
|1 site: 1.25 units to 5.0 units Up to 10 units per treatment|
|10% burden *||Both eyes: about 5,200 yen||Both eyes: about 5,200 yen|
|30% burden *||Both eyes: about 17,000 yen||Both eyes: about 17,000 yen|
* When using 50 units of botulinum preparation
There are two types of bottles containing botulinum preparations, 50 units and 100 units. The charge is fixed at 47,154 yen for 50 units and 84,241 yen for 100 units, and when receiving treatment, the injection procedure fee for the preparation is fixed. And inspection fee will be charged separately.
Once diluted, the formulation must be used up for the same person on the same day to prevent bacterial growth, and the price will vary depending on the quantity of formulation used for dilution, not the amount actually injected. To do.
The botulinum injection treatment performed around the eyes is a treatment aimed at treating wrinkles at the outer corners of the eyes and forming sagging eyes in cosmetic medicine, and is mainly used in general medicine for the treatment of blepharospasm and strabismus, which are covered by insurance . Therefore, depending on the symptom you want to improve, you need to choose a beauty medical institution or a general medical institution such as an ophthalmologist.
If you make a mistake in the injection amount or injection site of the botulinum injection, not only will you not be able to feel the effect, but there is also the risk of an unnatural expression and eyebrow ptosis .
In order to receive a more secure treatment, we will provide guidance on the treatment procedure to doctors who have a certificate given to practitioners who have taken seminars and courses held at botulinum pharmaceutical companies and doctors. One option is to choose a medical institution where your instructor is enrolled .
