Endo technique, consists of using a laser beam with a wavelength of 1470 nm emitted through an optical fiber inserted into the subdermal tissue in order to reduce subcutaneous fat and tone the skin through the intense production of collagen.
Patients were assisted with just one endo session, where the mandibular and submental regions were treated. It was by using 400 micron optical fiber, power ranging from 4 to 8 W, in continuous mode. After the procedure, patients were instructed to remain with a bandage on the treated area for 4 days and. Then, after this period they received 4 sessions of manual lymphatic drainage, which was performed once a week.
Results: After treatment and reassessment at the end of 60 days, it was noticed a clear decrease in fat in the cheeks, as well as in the submental region. Also, the skin where the jowl fat was removed underwent intense retraction, as it was seen a decrease in flaccidity and wrinkles.
Lately, the 1470 nm wavelength laser has started to be actively used in surgical procedures. Laser equipment with a wavelength close to 1500 nm has its absorption in water as a predominant characteristic generating specific biological effects. These lasers are water-absorbable or water-specific and are mainly used in urology and for endovenous obliteration of veins . However,authors reported that the 1470 nm diode laser is able to deeply penetrate into tissues due to its high affinity for water and also acting on fat. All due to it is understood that the richer a tissue is in water and fat, the better it will be. the transmission of this kind of laser and the smaller its dispersion. Therefore, using 1470 nm wavelength in non-surgical endo procedures has become very common nowadays.
Practical endo procedure in the submental region where the guide laser beam can be seen (wavelength in the red spectral range) indicating the location of the optical fiber end. After creating the orifice, a 22G/50mm cannula was introduced to create the fiber optic channels for passing and introducing the anesthetic (0.1 ml of Xylestesin with 2% vasoconstrictor) toward each vector. Still with the laser off and after anesthesia of the entire target area, the optical fiber was introduced up to the distal limit of the vector drawn on the skin. After, laser was turned on and the optical fiber was slowly removed from the subdermal region. Three to six turns were performed with the laser turned on. After the entire region had been irradiated with the laser, massage handling was performed in order to drain the emulsified fatty tissue through the orifice. Then, asepsis of the entire treated region was performed and a bandage with 50mm micropore.
