Removal of cosmetic oral mucosal tattoos with Nd:YAG laser—histological and clinical observations
Introduction
The cosmetic intraoral tattoos consist of insoluble ink particles injected in subepithelial connective tissue and ingested past phagocytic cells. These phagocytic cells do not remove the tattoo ink abroad from the mucosa and remain relatively stable. Intraoral tattoos can be divided into amateur and professional. Apprentice tattoos usually contain carbonaceous fabric from Indian ink, charcoal, or magnetite. They are injected into mucosa and commonly have the form of relatively simplistic linear lettering or designs. At that place is usually less particulate matter than in a professional person tattoo merely the depth of the tattoos may vary more than in an amateur tattoo. Professional tattoos can consist of a variety of inks and color using insoluble metal salts and organic complexes. They may exist densely colored and occupy pocket-size areas of the oral mucosa. The preferable site for oral tattoos is inner labial mucosa.
Despite the paucity of published data, mucosal lip tattooing is not a new miracle. The uses of intraoral degradation of exogenous pigmentation are diverse, ranging from gang identification to expressions of love (Figure 1). Notwithstanding, the orolabial mucosal tattoos occur infrequently (ane) and because they are hidden, the social stigma that may be associated with traditional tattoos is less of a motivating cistron for removal. Unexpected break-ups, changes in lifestyles, and similar reasons are ofttimes to arraign. A number of treatment modalities to remove tattoos could be used by analogy with the dermal tattoos, including surgical excision with grafting, mucobrasion, laser ablation and cryotherapy (2-4). All these treatments result in scarring and tissue deformities to some degree (ii-4).
Figure 1 Oral tattoos are usually localized over the inner labial mucosa and ranged in their messages—from boy/girlfriend names to favorite drink brands and football clubs (personal archive of Assoc. Prof. K Tomov).
The development of infrared lasers has revolutionized the ability to remove tattoo pigment finer with minimal scarring and is now widely considered the criterion standard treatment pick for skin tattoos. In laser tattoo removal, selective photothermolysis permits the selective destruction of tattoo paint with very limited damage to surrounding tissue (iv). The long-wavelength infrared light of the Nd:YAG light amplification by stimulated emission of radiation penetrates deeply (2–six mm) into skin. Blue or black pigments like melanin enhances Nd:YAG absorption, whereas pale colors raise its penetration. Although dark pigmented tattoo particles absorption is still poorly studied (dissimilar size and colour) there is a preferential assimilation of the Nd:YAG radiation sufficient to produce changes due to selective photothermolysis (iv).
Despite the oral localization of inner lip tattoos, the dentists are not familiar with both the problem and the possibilities to utilize laser for oral mucosa tattoo handling. The starting time and only known report of successful Nd:YAG Q-switched light amplification by stimulated emission of radiation removal of professional orolabial mucosal tattoos is published in 2011 past team of dermatologists —Kirby et al. (five). The primary wavelength of this laser is 1,064 nm. The authors reported for three patients with oral tattoos that responded exceptionally well to Nd:YAG Q-switched laser treatment. The suggestion of the authors is that Q-switched laser treatment is a condom and very effective ways of removing cosmetic mucosal tattoos on the inner lip and they considered Nd:YAG laser as standard treatment option in this scenario. Withal the authors generally stated the philosophy of laser treatment in corrective dermatology with pocket-sized reference to oral mucosa and its specificity. Additional there is no relevant histological data regarding effects of Nd:YAG laser on oral mucosa after tattoo removal procedures. The aim of this publication is to provide histological evidences for possibilities to remove successfully oral mucosa tattoos using 1,064 nm wavelength light amplification by stimulated emission of radiation.
Methods
Study design
In 2016 after approval past the Ethics Committee of Medical Academy of Plovdiv and written consent, a examination treatment of 5 patients with professional black tattoo of inner lip was performed with multi-wavelength laser (Delta Cube light amplification by stimulated emission of radiation, Erma Electronique, French republic) nether local anesthesia. The clinical process was conducted using 1,064 nm wavelength. Power output of 2 W/twenty kHz was applied (iv mm spot size and a fluency of 9.2 J/cm2) for few seconds to discolor the half of tattoo contour. Blanching was accomplished by aiming the laser in a moving pattern in a focused fashion (Figure 2). Follow-up and photo documentation occurred at intervals from two calendar week till two months. The procedures were repeated twice at interval of two months.

Test handling was performed using one,064 nm wavelength with power output of 2 Westward/20 kHz (4 mm spot size and a fluency of ix.2 J/cm2) for few seconds to discolor the tattoo in a focused fashion (B). Ii month later the treated area represents complete clearance without tissue deformities (C).
To obtain detailed information about the possible tissue alterations, 2 equal specimens were taken from the treated and non-treated sites for further histological evaluation (Figure 3). Each biopsy specimen was fixed in 10% buffered formalin, embedded in alkane series and so stained with Hematoxylin and Eosin and Trichrome (for selective demonstration of collagen fibers).
Figure 3 Case #2. Preparation for tissue sampling from treated and not-treated areas. The selected areas were marked past surgical ink (A) Biopsy was performed afterward patient's written consent (B). The tissue samples were stock-still in 10% formalin solution and were prepared for histological evaluation (C).
Results
Post-handling recovery was uneventful, with little hurting and swelling. Twelve months after the final procedure nigh invisible scarring were observed in all patients merely the mucosa color and texture were found normal.
Histologically, the specimens before the handling showed aggregates of ink particles presented within basal cells and fibroblasts (Figure 4A,B), predominantly in a perivascular location and surrounded by collagen fibers (Figure 4C). Tattoo particles had a hateful diameter of 3.52 µm. The specimens after the handling revealed fragmentation of black ink particles up to 1.v mm below the surface (Figure 5A,B). Tattoo pigment was progressively altered initially appearing as sharp-bordered grains of pigment in clumps and assuming a progressively amorphous form and lighter color afterward treatment. Mild fibrosis was seen in the superficial submucosal expanse where collagen fibers replaced the pigment-containing tissue altered by the laser (Figure 5C).

The histology evaluation demonstrates black ink granules localized around vessels in the upper and mid-epithelial in macrophages and fibroblasts—HE, 4× (A), ten× (B). Extracellular deposits of pigment are surrounded past loose connective tissue with characteristic structure - Trichrome, 10× (C).

Clinically, the handling results showed excellent recovery of the oral mucosa. One year later, the tattoo areas were healthy and without esthetical and functional disturbances (Figure vi).

Word
Different wavelengths take been used for selective removal of tattoo in dermatology (6). For example, Q-switched ruby (694 nm wavelength) at half dozen–8 J/cmii, and Q-switched alexandrite (755 nm wavelength) at 4–8 J/cm2, and Pulsed dye light amplification by stimulated emission of radiation (510 nm wavelength) at 3 J/cm2 have been used in removing tattoos. Currently the Nd:YAG laser (1,064 nm wavelength) is considered as aureate standard in tattoo removal in dermatology. The chief disadvantage of the i,064 nm wavelength is the limited colour range, which is basically restricted to blackness and dark blueish/black tattoo paint. However the oral tattoos are predominantly dark colored. The proposed mechanism is that the tattoos pigments absorb the laser energy and this produces very high light intensities upwardly to gigawatts. Within the pigments, this lite is converted into oestrus within nanoseconds, producing an increase in temperature above 1,000 °C (photothermal issue). This rapid thermal expansion produces shock waves and a potential localized cavitation, so called photoacoustic shock which leads to a particle fragmentation and selective death of pigment containing cells. There is also at the same time a breaking in the chemical bonds inside the paint (photochemical result) (4,v,7).
At that place are no previous reports on histological changes afterward laser-assisted tattoo removal of oral mucosa. The bachelor analysis of the Nd:YAG light amplification by stimulated emission of radiation-induced changed in dermal tattoos has been washed by light and/or electron microscopy (8,9). Biopsy of treated tattoos revealed fragmentation of tattoo particles. Little, if any, fibrosis was observed in the superficial dermis. Kilmer et al. (ix) noted that despite initial tissue amending, the lack of both clinical scarring and histologic scarring is most likely attributable to the lack of thermal injury to collagen. The dermis and the epidermis sustain mechanical injury from the photoacoustic wave, but this trauma is evidently highly reparable. Textural changes generally resolve within 4–6 weeks, suggesting an optimal handling interval of 6 weeks or longer. The majority of patients show no evidence of severe fibrosis or granulomatous change in the late postoperative period. The thinner non-keratinized and well vascularized oral mucosa enable better penetration and suggested more significant thermal furnishings. Our histological observation are similar to the findings of other authors, nonetheless signs of mild fibrosis were axiomatic (6,8). The histologic clearing correlated with clinical clearing of pigmentation where the fibrosis observed histologically does not interfere with the functional and esthetics results.
Nevertheless laser tattoo removal is uncomfortable. Depending on the patient'south pain threshold, some grade of local anesthesia is required. Pre-treatment might include the application of an anesthetic gel under occlusion for five–ten minutes prior to the laser handling session. A meliorate method is infiltrative anesthesia which tin can be administered locally by injections of Ubistesin (articaine hydrochloride 4% with epinephrine ane:200,000). Treatments are repeated at four- to eight-calendar week intervals, with ii to iii treatments necessary depending on density of tattoo pigmentation and patients' expectations. Side effects with the Nd:YAG light amplification by stimulated emission of radiation are rare and includes transitional swelling, erythema, pinpoint haemorrhage, pain sensation (10). The incidence of textural change is less than with the other methods. More than reaction occurs early in a class of handling because of the density of pigment and lower fluences for the outset one or ii treatments can minimize this. The largest spot size available (4 mm) is used with fluence of ix.ii J/cm2. Pocket-sized spot sizes and college fluences are more probable to produce pinpoint bleeding. Immediately afterward treatment in that location is a greyish discoloration of the surface area. Healing ordinarily gain uneventfully, with discoloration fading subsequently seven–14 days.
Conclusions
As tattooing is becoming more and more popular at that place is an increasing corporeality of people requesting tattoo removal. Although inner lip tattoos are nonetheless rare, it is conceivable that, as tattoos become more prevalent, the want to remove them, including those located on mucosal membranes, will increase also. Within the last decade, Nd:YAG lasers have significantly improved the effectiveness of tattoo removal. The histological studies provided new information and nosotros tin amend empathize the mechanisms of pigment elimination. This publication contributes our noesis with histological evaluation of Nd:YAG light amplification by stimulated emission of radiation removal of professional person orolabial mucosal tattoos. It is the contention of the authors that Nd:YAG laser treatment is a condom and very effective means of removing corrective mucosal tattoos on the oral mucosa and should be considered the criterion standard handling option in this scenario.
