What is laser ablation?

Laser ablation is a modern medical technique that uses tightly focused laser energy to break down, melt, or remove unwanted or abnormal tissue with high accuracy. The heat generated by the laser affects only the targeted area, allowing for the treatment of small, sensitive, or deep-seated lesions without harming nearby healthy structures. Because the intensity and depth of the laser can be precisely controlled, doctors use this method across many fields to manage growths, blockages, surface lesions, and other tissue abnormalities.
A major advantage of laser ablation is that it is minimally invasive, often requiring only a small entry point or no incision at all. This leads to less bleeding, reduced discomfort, and a quicker return to normal activities when compared with traditional surgical procedures. Patients benefit from shorter recovery times, fewer complications, and better cosmetic results. These advantages have made laser ablation a preferred option in specialities such as dermatology, oncology, neurosurgery, ENT, gastroenterology, and vascular care.

How does laser ablation work?

Laser ablation works by directing a concentrated beam of laser energy onto the specific tissue that needs to be removed or destroyed. When the laser hits the target, its energy is absorbed and converted into heat. This heat causes the cells in that area to break apart, vaporise, or shrink, depending on the type of tissue and the laser settings used. Doctors can adjust the wavelength, intensity, and duration of the laser pulse, allowing them to control exactly how deep and how quickly the tissue is treated. This precision makes it especially useful for delicate structures or areas where accuracy is critical.
During the procedure, the surgeon uses imaging or visual guidance to ensure the laser only affects the intended spot while preserving the surrounding healthy tissue. Since the treatment is highly focused, there is minimal bleeding and very little damage to nearby areas. As the treated tissue is removed or reduced, symptoms improve, and normal function can return. The controlled nature of the laser energy makes the procedure safer, gentler, and more effective than many traditional surgical methods, which is why laser ablation is widely used across multiple medical specialities.

Types of Laser Ablation:

1. Thermal Laser Ablation
Uses heat from continuous or pulsed laser energy to destroy or vaporise tissue.
Commonly used in dermatology, oncology, and soft-tissue procedures.
2. Photoablation
Uses high-energy ultraviolet (UV) lasers to break molecular bonds and remove extremely thin layers of tissue without significant heat.
Often used in eye surgeries (e.g., refractive procedures) and for precise surface treatment.
3. Plasma-Mediated Ablation
Creates a plasma field at the tissue surface, leading to rapid vaporisation.
Helps in delicate surgeries requiring minimal thermal spread.
4. Laser-Induced Thermal Therapy (LITT)
A controlled method where heat from a laser probe destroys deeper tissues.
Common in neurosurgery and tumour treatment.
5. Selective Laser Ablation
Targets specific tissues based on their colour or absorption properties (e.g., pigmented lesions, vascular lesions).
Useful in dermatology and cosmetic surgery.
6. Endovascular Laser Ablation
Used inside blood vessels to close or shrink abnormal veins, such as in varicose vein treatment.
Delivers laser energy through a thin fibre inserted into the vessel.
7. Laser Lithotripsy (Stone Ablation)
Breaks stones (kidney, ureteric, gallbladder or bile duct stones) using laser pulses.
Stones are fragmented into tiny pieces that can be naturally passed or removed.

Conditions Treated Using Laser Ablation Procedures:

Laser ablation is widely used across various medical specialities to accurately remove or shrink abnormal tissue while minimising discomfort and reducing recovery time. This precise, minimally invasive technique allows clinicians to target specific problem areas effectively, making it suitable for a broad range of conditions.

• Skin conditions: warts, moles, skin tags, scars, and pigmented lesions
• Cancer care: small tumours in the liver, lung, kidney, and other organs
• Neurosurgical conditions: brain tumours, seizure-causing lesions, and spinal abnormalities
• Vascular disorders: varicose veins and vascular malformations
• ENT problems: nasal polyps, enlarged turbinates, and vocal cord growths
• Urology conditions: kidney stones, ureteric stones, and prostate enlargement (BPH)
• Gastrointestinal issues: bile duct stones and selected polyps or strictures
• Gynecologic changes: cervical dysplasia and other precancerous lesions
• Pain-related disorders: targeted nerve ablation for chronic pain
