India ink tattoo for radiation treatments skin#
Most of the data on the use of these devices are on Fitzpatrick skin types 1 to 3. Significant advancements have been made in laser technology for pigmented lesions with new and better equipment being introduced every year. Light Amplification by Stimulated Emission of Radiation (LASER) uses the principle of selective photothermolysis. Textural changes and scarring occur rarely. Complications and their management: Postinflammatory pigmentation changes are common in dark skin patients. Laser parameters: Laser parameters vary with area, type of pigmentation and machine used. Dermal lesions and tattoos tend to remain clear after treatment (except conditions as dermal melasma). Therefore, there is a need for continued sun protection. Epidermal lesions are likely to recur even after complete clearing. Hence, a realistic expectation and proper counseling is very important. Future maintenance treatments may be needed. All lesions may not clear completely and only lightening may be achieved even after multiple sessions in many cases. Treatment sessions: Epidermal lesions need an average of 1−6 sessions, while dermal lesions need average of 4−10. Informed consent should be taken in all cases. Detailed counseling about the need for multiple sessions is required. History of scarring, response to previous injuries, degree of tanning needs to be considered. Investigations to identify any underlying cause for pigmentation are important concurrent topical and systemic drug therapy may be needed. Patient selection: Proper patient selection is important. Relative: Keloid and keloidal tendencies, patient on isotretinoin, history of herpes simplex, patient who is not co-operative or has unrealistic expectation. Contraindications: Absolute: Active local infection, photo-aggravated skin diseases and medical conditions, tattoo granuloma, allergic reactions to tattoo pigment, unstable vitiligo and psoriasis. Mixed epidermal and dermal lesions: Postinflammatory hyperpigmentation (PIH), nevus spilus, periorbital and perioral pigmentation, acquired melanocytic nevi (moles), melasma and Becker's Nevus.
Tattoos: Amateur, professional, cosmetic, medicinal, and traumatic. Dermal lesions: Nevus of Ota, Blue nevus, Hori's nevus (acquired bilateral nevus of Ota-like macules). Indications: Epidermal lesions: Cafι au lait macules (CALM), lentigines, freckles, solar lentigo, nevus spilus, pigmented seborrheic keratosis, dermatosis papulosa nigra (DPN). Facility: The procedure may be performed in the physician's minor procedure room. He should have adequate knowledge of the machines, parameters, cooling systems, and aftercare.
Physician Qualification: Laser may be administered by a dermatologist, who has received adequate background training in lasers during postgraduation or later at a center that provides education and training in lasers, or in focused workshops which provide such trainings. Proper knowledge of the physics of laser machine, methodology, dosage schedules, etc., is mandatory. Machines: Though different laser machines are used, Quality-switched (QS) lasers are considered as the gold standard for treatment of pigmented lesions. Abstract Introduction: Lasers have revolutionized the treatment of pigmentary disorders and have become the mainstay of therapy for many of them.
