CLS Tattoo Removal and Pigmentation Treatment 3

Question 1

What is the Kirby-Desai scale used for in laser tattoo removal practice?

Accepted Answer

Predicting the number of treatments required for significant tattoo clearance based on multiple clinical factors

Answer

Measuring the depth of ink deposition using ultrasonography

Answer

Grading the severity of post-treatment complications

Answer

Classifying tattoo ink colors by their absorption spectra

Question 2

When treating a multicolored tattoo, what is the recommended approach for wavelength selection?

Accepted Answer

Sequence treatments starting with lighter colors first, using the appropriate wavelength for each pigment color

Answer

Use 1064 nm for all colors at maximum fluence to simplify protocol

Answer

Treat all colors simultaneously with IPL broad-spectrum light

Answer

Use 532 nm for all colors except black, which requires 1064 nm

Question 3

After aggressive Q-switched laser treatment of a large tattoo, a patient develops hypopigmentation that persists at 12 months. What is the most appropriate explanation?

Accepted Answer

Excessive thermal damage from overlapping pulses or excessive fluence permanently destroyed melanocytes in the treated dermis

Answer

The patient's immune system cleared both ink and melanin via the lymphatic system

Answer

Hypopigmentation at 12 months is normal and expected to fully resolve by 18 months

Answer

The tattoo ink bleached the surrounding melanin through a photochemical reaction

Question 4

A patient has a new dark tattoo placed 2 weeks ago and requests immediate laser removal. What is the most appropriate response?

Accepted Answer

Advise waiting at least 6–8 weeks for complete healing; treating fresh tattoos risks poor wound healing and increased adverse events

Answer

Begin treatment immediately at lower fluence as fresh ink is easier to fragment

Answer

Treat half the tattoo now and half at the next session to test response

Answer

Use a picosecond laser instead of Q-switched to safely treat fresh ink

Question 5

Solar lentigines (age spots) and café-au-lait macules are treated with Q-switched lasers. What parameter distinguishes successful treatment of solar lentigines from incomplete response?

Accepted Answer

Immediate frosting limited to the pigmented lesion that spares the surrounding skin

Answer

Complete blanching of the entire face after a single treatment pass

Answer

Patient-reported cessation of pain during the laser pulse

Answer

Visible carbonization of the lesion surface

Question 6

Which statement best describes the management of an allergic reaction to tattoo ink that develops after laser treatment?

Accepted Answer

Laser fragmentation can release antigens from ink particles, triggering or worsening allergic reactions; dermatologist co-management and possible systemic treatment may be required before continuing laser sessions

Answer

Laser treatment accelerates ink removal and should continue; manage allergy with antihistamines alone

Answer

Allergic reactions to tattoo ink are always mild and self-limiting; no intervention is needed

Answer

Switch to a different laser wavelength to avoid activating the allergen
