Working with cosmetic surgery, in 25 years I performed several techniques for facial flaccidity beyond the plastic surgery that were presented in congresses and workshops with the goal of minimizing scars leading to a pos-op with less trauma, less edemas, aiming good results in medium average time.
Since I met Doctor Nikolay Serdev in 2001 during the International Congress of Esthetic Medicine in Brazil I became very interested in a new technique for facial flaccidity, developed by him, which lifts and fix mobile fascias to immobile fascias/periosteum, with semi-elastic threads from Bulgaria. That procedure was baptized as “Serdev Sutures”.
After analyzing for years the follow up and results of “Serdev Sutures” procedures for cervical flaccidity, I decided to combine two techniques that would give an excellent retraction of lower SMAS – platysma, sunken skin aspect especially in the submandibular zone improving the jaw line.
I started to perform this technique on selected patients, observing their complaints carefully and thinking if I could give them long lasting results and what anatomic structures I should handle to obtain an harmonical retraction of platysma and surrounding tissues, as dermis and epidermis, always respecting the natural look of the patient.
The aim of modern aesthetic surgery is to create aesthetic forms and proportions for the face and body with the purpose of beautification. In the Aesthetic Cosmetic Surgery rejuvenation which means the same of beautification, by giving the right proportions and angles, typical for young people. In the last decade surgery was renovated, based on the experience of many specialties, increased technology and computer devices.
Lower face lifting techniques to repair the laxity and ptosis of tissues were submitted to invasive procedures with visible scars pre and retro auricular. Recently these techniques were replaced by more simple procedures. One of these is the scarless "Serdev Suture" liftings used in this case to restructure and reposition the “subdermal facial mask”. The idea of lower SMAS–platysma face-lift using semi-elastic long term absorbable sutures is to tighten and elevate the lower face and neck, together with facial soft tissues without unnecessary incisions. As we know that soft tissues and skin are attached to the SMAS and platysma, lifting and fixing them in better position, aims repositioning of other facial structures as well. In young patients where no real ptosis exist, heavy faces, not well-expressed cheekbones, mandible arch, bad proportions, angles and sad look should be corrected.
One cannot expect the same results from this technique as from other excision surgery. However the suggestion for carrying out this technique under local anesthesia and that patient leave the clinic at the end of the procedure and rapidly recover their normal life is encouraging.
Results and duration vary from person to person according to each case, state of skin and subcutaneous tissue. There is no unique procedure in aesthetic cosmetic surgery for perfection of beauty. Other mini-invasive techniques as peelings, PRP, liposowing and fillers can be an addition to “Serdev Suture” techniques to keep significant results and satisfaction.
With age, loosening of SMAS and facial fascias, atrophy of ligaments due to the gravity, causes sagging of the neck and results in an aged face. Jawing is caused by displacement of the SMAS and aging of the skin. (Figs. 1 and 2)
The neck is a face related area and an important part of the aging face. The SMAS is a fibro-muscular layer that connects platysma and galea and acts as a suspension for the overlying facial skin. (Fig. 3)
Performing face lift surgery, the continuity between aponeurotic facial fascia and the platysma is an anatomical fact that is very useful for surgeons. The SMAS lies deep to the subdermal plexus of vessels and superficial to the motor nerves of the facial musculature. It provides a suspensory sheet, which distributes forces of facial expression, mimetic and overlying skin. The idea that suspending this layer leads to a better long-term suspension has become common. (Fig. 4)
SMAS overlies the parotid gland in mandibular angle and tends to be substantial and easy to handle, because the parotid gland, zeugmatic major and minor muscles protect underlying facial nerve branches. With regard to protecting the facial nerve structures, we can accept that Serdev lower SMAS-platysma face-lift “by sutures only” or “with retro-lobular incision” is done in a fairly secure area.
4. First technique for cervical flacidity procedures
The first proposed by Serdev technique was done with a 1cm retro auricular incision, careful dissection of subcutaneous tissue reaching platysma, clamping it and traction it with a mosquito. It fixation to mastoid periosteum was done with a 3-0 thread. After a time the same technique was performed with Serdev needle and semi elastic thread, without incisions, using only a tinny perforation at the retro auricular zone and some centimeters in front of the sternocleidomastoid muscle. Results depend on the flaccidity status of the skin, fat tissue amount and not too much hanging skin in the submandibular zone.
From this point, desiring to develop a technique that could give patients a good result, despite of high level of flaccidity in the submandibular zone, and aiming also a better definition of jaw line, I increased some alterations on classic techniques.
5. Surgical technique
The skin perforation points as well as fixation to colli fascia, mastoid or occipital periosteum should be planned previously, while the patient is sited or standing up in the surgical room, after photographing the face in standard protocol, the patient is asked to lay down marking the points where the needle will pass with a special surgical pen. The main points are marked over mastoid, 4cm from the sternocleidomastoid muscle, over the platysmal bands if they are visible and at the same places on the other side. Lidocain 2% with adrenaline is used to numb the region. (Fig. 5)
I start with a tiny incision using a scalpel blade number 11 from where a Serdev needle number 60 is introduced to reach the mastoid periosteum. Having a good tangential fixation to mastoid I move the needle towards subcutaneous tissue superficial to sternocleidomastoid muscle. Attention should be paid to superficial vessels as well as to the internal jugular vein and artery, passing above the sternocleidomastoid muscle avoiding any nerve and vessel damage (Fig. 6).
With a twisting movement I continue moving, pointing the tip of the needle down to reach platysma that is punctured in a zigzag way and getting out through the skin marks in a 90 degree angle avoiding dermal damage. (Fig. 7)
The needle is loaded with a number 2 semi-elastic thread and the needle is pulled through the first entry point. This thread has to be long enough to reach both sides twice. (Fig. 8)
The procedure goes along the same way using a Serdev needle 140 zigzag through platysma and additional skin perforations, until it reaches mastoid periosteum of the opposite side where the other thread’s end will be exteriorized (Fig. 9).
Enough thread should be present to return until the submenthal mark is reached, where both thread ends will be tied with three knots which are made while the patient is sited, with medium elastic tension. (Figs. 10a and 10b)
This will direct the skin flaccidity upwards improving the anatomical mandibulo-cervical angle, the mandibular line, and the sagging neck as well. (Figs. 11a and 11b)
Possible skin dimples can be managed by pulling the skin laterally and away from the suture using a “mosquito” instruments. (Fig. 12.)
The Serdev Suture for platysma generally shows excellent results. There are no visible scars, no sign of any operative intervention and no “operated” appearance at all. The patients are submitted to local anesthesia and the method is minimally invasive, that means, without severe surgical cuts or incisions. The day after the procedure the patient is back to normal life. (Figs. 13. and 14.)
Having performed seventeen patients with an indication of the modified technique over the past two years, some complications were observed, such as: two patients had pain in the first two days in front of the sternocleidomastoid, one of which also showed shrinkage the skin in this area. Detachment of the dermis with 18 gripped needle has been successful in improving the pain the day after. The other patient, from outside São Paulo, visited a plastic surgeon on her town who removed the thread.
Other four patients complained of discomfort in the mastoid region. Infiltration of 0,2ml of Dexametazone plus 0,2ml of 1% Lidocaine with epinephrine symptoms improved significantly after two days. One patient reported inflammation and infection at the place of the knot. Antibiotics and drainage of localized collection solved the problem without having to remove the thread. The degree of patient’s satisfaction is high due to the simplicity of the technique and immediate results. Weekly follow up helps to solve complications.
Beautification and immediate social activity are the first and most important patient’s requirements. Classic rhytidectomy, in the past years were replaced by minimal invasive procedures with hidden incisions within the hair, extending around the earlobe and retroauricular area. Subperiosteal endoscopic surgeries have also been proposed. In recent years, with increasing demand of patients due to modern lifestyle, requiring less invasive surgical procedures with no visible scars, the Serdev’s Sutures were developed, which give patients an optimal solution for face and neck beautification while preserving the natural appearance at the same.
In the case of medium flaccidity in the lower region of the SMAS and platysma, the first Serdev technique is recommended. In cases of excess sagging of the neck and laxity in the submental area, the extended modified technique (Serdev - Tullii), is a valid alternative to stretch the neck, the lower SMAS and platysma, anchoring them to the retroauricularly positioned mastoid. Also, the laxity of the submental area is affected by the suture elevating the hole area.
When the facial skin is also very flaccid, dermal rejuvenation techniques are employed (PRP, Peelings), to improve skin tonus prolonging the results.
If there is excess fat located in the submental region, first we should perform an ultrasonic liposuction with local anesthesia. The skin will retract sticking largely to the deep plane, avoiding extended surgeries. After months it could be necessary to add the first Serdev suture technique as a complement. Also, an submental incision would be performed with plications of the platysmal bands fixating one above the other with two folds.
The “Scarless submental platysmal suture band” using skin needle perforations only, or in combination with the Serdev suture lift techniques in lower face and neck “by hidden retro-lobular incisions” provide a safe and effective method for beautification of flaccid neck and submental area, as an independent procedure or combining with other techniques of rejuvenation in order to solve face and neck ptosis and aging appearance.
The platysmal Serdev – Tullii suture band in the submental area achieves a bidirectional lower face and neck lift, correction of submental area laxity. It is a safe and effective procedure that gives a pleasant result, the patient obtains a younger appearance maintaining a natural and harmonic expression without plastic surgical incisions. After the surgery there is minimal swelling and business people can work normally.
This much desirable effect of the method is immediate, without visible scars and fulfills patient’s desires.
In cases of localized submental fat, the ultrasonic assisted liposuction in combination with our method is helpful to give the good definition of the cervicomandibular angle.
