Description

The invention relates to plastic and cosmetic surgery and can be used for augmentation (correction of the shape and size) of the lips.

There is a known method [RU 2680288, C1, A61B 17/00, 02/19/2019], including the execution of an incision, de-epidermis of the flap, use of the red border of the lips as a guide and suturing of wounds, while pre-de-epidermis a strip of skin under the nose with a width of 4-6 mm and a thickness of 0.2-0.5 mm, the dermal-subdermal layer is excised, the dermosubdermal flap is cut out, an autograft is formed from it in the form of an individual shape using a cutting tool, hold sutures are fixed at each end of the autograft, along the edges of the upper or lower lip two vertical incisions are formed, a tunnel is made through them under the red border of the upper or lower lip, the formed autograft is inserted into the tunnel and centered in relation to the lip symmetry line, the retainer sutures are removed.

A feature of this method is that scissors are used as a cutting tool, each of the fixation elements is made of 3-0 prolene threads, and vertical cuts are sutured with 5-0 prolene threads.

The disadvantage of this technical solution is the relatively high injury risk caused by the need for incisions.

The closest in technical essence to the proposed method is [RU 22144179, C1, A61B 17/00, 20.10.2003], which includes making two lateral cuts on the inner surface of the mucous membrane of the lip, located above and parallel to the corners of the mouth, forming a tunnel through the resulting cuts, introduction of a previously prepared skin graft of the required shape into the latter and fixing it to the mucous membrane of the lip, while additionally above and below the graft, 2-3 pairs of mucosal incisions with a length of 0.1-0.3 cm are performed, through which threads from absorbable material are passed with the capture of a part of the circular muscle of the mouth, pull them up to the inversion of the red border outward and tie, and as a graft, a skin-fat flap of the operated patient is used.

The peculiarities of the closest technical solution is that lateral incisions of the mucous membrane are performed, departing 0.2-0.7 cm up from the corners of the mouth, the graft has an almond shape with a length of 4-6 cm and a width in the central part of 0.3-1.0 cm, incisions in the mucous membrane of the lips are sutured with Vicril rapid 5/0-6/0 threads, and Vicril coated 2/0-3/0 is used as tightening threads.

The disadvantage of the known methods for correcting the shape and size of the lips is that liquid implants are used, which are dissected and migrated in the tissues, which reduces the effectiveness and stability of the correction.

The disadvantage of the closest technical solution is the relatively high injury risk caused by the need for incisions. In addition, the known method has a relatively narrow field of application, since the method provides for the correction of the shape of only the upper lip.

All this narrows the arsenal of technical means that can be used for lip correction.

The problem that is solved in the invention is aimed at developing a method that has a wider field of application and can be used for simultaneously augmentation of the upper and lower lips, and also has increased trauma safety.

The required technical result is to increase trauma safety and expand the scope by providing augmentation of both lips.

The problem is solved, and the required technical result is achieved by the fact that, in the method in which surgical threads are used, according to the invention, the first surgical thread is inserted from the point of injection with an 18G needle at the angle of the mouth at a distance of 1.5 cm from one side. along the contour line of the upper lip along the border of the red border of the mucous membrane and the skin of the upper lip with a puncture at a similar point on the other side, from the point of injection with an 18G needle at the level of the corner of the mouth at a distance of 1.5 cm on one side, a surgical thread is introduced along the contour of the lower lip along the border of the red border of the mucous membrane and the skin of the lower lip with a puncture at a similar point on the other side, from a point at the level of the corner of the mouth by 1.5 cm on one side, a puncture is made with an 18G needle and the thread is inserted along the line parallel and 0.5 cm above the contour line upper lip with a puncture at a similar point on the other hand, while using a surgical thread in the form of a tightly wound micro-spiral made from polycaprol copolymer acton and L-lactic acid.

In addition, the required technical result is achieved by using a 4/0 USP surgical suture.

In addition, the required technical result is achieved by using a 5/0 USP surgical suture.

In addition, the required technical result is achieved by the fact that when introducing a surgical line, a thread with a length of 1000 mm is used, which is previously tightly wound on a blunt-end cannula 22G with a length of 70 mm.

The illustrative materials show:

in fig. 1 is an example of a surgical thread in the form of a tightly wound micro-spiral;

in fig. 2 is an example of a 22G cannula with a length of 70 mm with wound surgical suture in the form of a tightly wound microcoil; figure 3 is a diagram of the introduction of surgical threads.

The minimally invasive method of lip augmentation is implemented as follows.

To implement the proposed method can be used surgical suture 4/0 USP or 5/0 USP in the form of a tightly wound microcoil (Fig. 1), produced from a copolymer of polycaprolactone and L-lactic acid. Thread length from 1000 mm. The suture is tightly wound on a 70 mm long blunt cannula 22G (Fig. 2).

In the proposed technical solution, it is proposed to introduce surgical threads through the injection point and withdraw from the injection point (Fig. 3).

The main directions are as follows:

- from a point at the level of the corner of the mouth, for example, on the right, a puncture is made 1.5 cm with an 18G needle and a thread is inserted along the contour line of the upper lip along the border of the red border of the mucous membrane and the skin of the upper lip with a puncture at a similar point on the left side;

- from a point at the level of the corner of the mouth, for example, on the right, a puncture is made 1.5 cm with an 18G needle and a thread is inserted along the contour of the lower lip along the border of the red border of the mucous membrane and the skin of the lower lip with a puncture at a similar point on the left side;

- from a point at the level of the corner of the mouth, for example, on the right, a puncture is made 1.5 cm with an 18G needle and the thread is inserted along the line parallel and 0.5 cm above the contour line of the upper lip with a puncture at a similar point on the left side

Clinical practice example

15 operations were performed to correct the shape of the lips using surgical threads in accordance with the proposed method.

The postoperative periods in all patients were uneventful. The observation period is up to 6 months. The sufficient effect of the operation persisted during the observation period in all patients.

The proposed method is distinguished by significant injury safety, since performed without cuts. Its implementation ensures reliable and long-term fixation and augmentation of the soft tissues of the lip due to the implantation of threads in the subcutaneous layers. This achieves the required technical result.
