Possibilities of botulinum toxin injections for the correction of aesthetic defects of the nose

Non-surgical rhinoplasty is a popular non-invasive method for correcting age-related or congenital aesthetic defects of the nose in men and women. The procedure allows not only to save money and reduce the recovery period, but also to harmonize the face by making small changes to the nose area. Botulinum toxin injections, according to Dr. Ahmed El Houssieny, allow for effective and safe aesthetic correction of the nose.

Safety First: Things to Consider When Correcting a Nose with Botulinum Toxin 

Onabotulinum toxin type A

– a safe and effective drug that is used in the middle third of the face off-label. Therefore, a practitioner performing nose correction with botulinum toxin injections must definitely understand the anatomy of the facial muscles, their functions and interactions. Introducing the toxin into the

correct plane

and preventing it from diffusion – important rules for working in the middle and lower thirds of the face, where muscle fibers are often intertwined. Moreover, the muscles in these areas may be more sensitive to the effects of botulinum toxin type A, and therefore

lower doses

of the drug are usually required for correction.

How to properly dose and administer botulinum toxin preparations This article describes approaches to the correction of aesthetic defects of the nose using onabotulinum toxin type A. For this purpose, the author recommends using 1 ml of bacteriostatic saline to dilute the vial of

100 units.

onaBTX-A to avoid diffusion of the toxin into adjacent muscles. Muscles in the middle third of the face may be more sensitive to the effects of botulinum toxin type A, and therefore, as a rule, lower doses of the drug are required for correction.

The procedures described may be carried out no more than

every three months

The formation of

rabbit wrinkles

is facilitated by contraction of the transverse part of the nasal muscle. The approach to the correction of this aesthetic defect is selected individually for each patient. As a rule,

2–5 units are injected first. onabotulinum toxin A

into the transverse part of the nasal muscle on each side of the nasal spine. In about

40%

of patients this results in a visible smoothing of wrinkles, while in 60% of patients persistent wrinkles are observed:

near the root of the nose, arising from the activity of the nasal part of the orbicular muscle of the eye;

• between the root of the nose and the medial border of the eyebrow and between the eyebrows;
• around the indentation under the ala of the nose, resulting from the contraction of the muscle that lifts the upper lip and ala of the nose.
If 2 weeks after the first botulinum toxin injection, the patient develops

additional wrinkles

, 2 units of the toxin are injected into the appropriate problem areas to correct them. To limit drug diffusion, it is important to inject the toxin into the target muscle medially rather than laterally when correcting rabbit wrinkles.

It is worth noting that:

Diffusion of the toxin into the levator labii and ala of the nose, as well as the levator lip, can lead to

asymmetry, lip ptosis
• , and impaired speech and eating function ; diffusion of botulinum toxin into the orbicular muscle of the eye can lead to
impaired lacrimation
• ; injecting the drug too low or too deep into the walls of the nose can lead to damage to the angular artery or vein, the occurrence of
ecchymosis or hematomas
• .
In order to

to minimize the spread

of the drug, when working with this area, the needle is inserted intradermally or into the superficial subcutaneous plane.

eyebrow wrinkles

, it is recommended that they be corrected at the same time as rabbit lines. This will prevent compensatory contraction of the transverse nasal or prostrate muscles, with subsequent formation of either horizontal wrinkles at the root of the nose or secondary rabbit wrinkles. To work with the proud muscle, it is recommended to use

3–5 units of toxin

a. Ptosis of the tip of the nose: treatment with botulinum toxin injections

 

Descent of the tip of the nose

may be the result of age-related changes or the effects of gravity in combination with overactivity of the muscle that depresses the nasal septum. In some patients, the tip of the nose moves during a conversation. It is worth noting that

botulinum toxin type A

will not be effective in patients with genetically determined ptosis of the nasal tip, which is not mobile. Problems related to the nasal septum or cartilage structures require a different approach. The key to successful correction of nasal tip ptosis is to determine the etiology of the problem.

muscle score

of the patient. For the descent of the tip of the nose, not only the muscle that lowers the nasal septum is responsible. For example, the intertwining of the fibers of the depressor septum and the dilatator nostril means that some people may experience dilatation of the nasal cavity and rotation of the nasal tip when they smile or make certain sounds. In some patients, the dynamics of the depressor septum and the levator lip and ala of the nose can cause the lip to rise and the tip of the nose to drop down simultaneously, resulting in a horizontal crease in the area of ​​the upper lip during mouth movements. This line can be corrected by injecting

1–3 units

botulinum toxin into the levator lip and alae and depressor septum muscles. In order to inject the drug exactly into the muscle that lowers the nasal septum, it is necessary that the patient lowers the upper lip – thus, the muscle lengthens and separates from the orbicular muscle of the mouth. The doctor then injects the drug into the

columella

, holding it with his free hand or pressing on the tip of the nose.

Botulinum toxin use in oral surgery The required dose of botulinum toxin also depends on the

muscle strength

and therefore it is important to evaluate it at rest and during mobility by palpation. More "strong" muscles are characterized by deeper lines, greater mobility and greater muscle mass. For the depressor septum muscle, the dose of onabotulinum toxin A varies within

2–5 units

. If the fibers of this muscle are intertwined with the fibers of the muscle that dilates the nostrils, additional injections of botulinum toxin into both wings of the nose on both sides of the nose tip may be required to lift the nasal tip. minimum doses of the drug should be administered to avoid diffusion into the levator muscles of the lipss. Alar flaring: botulinum toxin correction

Swelling of the wings of the nose occurs due to contraction of the muscle that dilates the nostrils. Injections of small doses of botulinum toxin can weaken this muscle and eliminate the aesthetic defect.

The procedure will be effective for patients who can voluntarily inflate their nostrils. Patients with a broad bridge of the nose and base of the alae may have well-developed nostril dilators, as well as the medial alar of the levator lip and ala of the nose.

Botulinum toxin in the treatment of migraine Subcutaneous toxin injections are given at the

point of greatest contraction

of the nostril dilator muscle at the ala alae. Most often it is midpoint. In order to avoid diffusion of the drug into the levator muscles of the lips, botulinum toxin should be injected

medially

. The dose of the toxin varies in the range of 2-10 units for each side of the face. According to
