Sample interview questions: Can you explain the concept of laser-induced thermal therapy and its significance in dermatology?
Sample answer:
-
Concept of Laser-Induced Thermal Therapy (LITT):
-
LITT involves using lasers to generate heat in targeted tissue for therapeutic purposes.
- Laser energy is absorbed by tissue components, leading to a temperature rise and localized tissue damage.
-
The extent of tissue damage depends on various factors such as laser wavelength, power, exposure duration, tissue type, and laser-tissue interactions.
-
Significance in Dermatology:
-
LITT offers a precise and minimally invasive treatment approach for various dermatological conditions.
- It enables highly localized and controlled tissue ablation, minimizing collateral damage to surrounding healthy tissue.
- LITT can target specific tissue depths, allowing for selective treatment of lesions without damaging deeper structures.
-
It promotes faster healing and often results in improved cosmetic outcomes compared to traditional surgical methods.

Applications in Dermatology:
a. Vascular Lesions:
– LITT is effective in treating vascular lesions such as port-wine stains, hemangiomas, and telangiectasias.
– Laser energy targets the blood vessels, causing coagulation and eventual disappearance of the lesions.
b. Pigmented Lesions:
– LITT can treat pigmented lesions such as solar lentigines, ephelides, and nevus of Ota.
– The laser selectively targets melanin, the pigment responsible for the lesion’s color, leading to its destruction.
c. Skin Resurfacing:
– LITT is used for… Read full answer
