laserelectrosurgical

Laserelectrosurgical refers to procedures and devices that combine laser energy with electrosurgical current to cut, coagulate, or ablate tissue. It encompasses systems that deliver laser energy alone, as well as integrated platforms that apply laser and high-frequency electrosurgical energy through the same or interconnected handpieces.

The mechanism blends photothermal tissue effects from lasers with the controlled heating produced by radiofrequency (RF) current. Lasers provide precise tissue vaporization and dissection, while electrosurgical current promotes coagulation and hemostasis. Common laser wavelengths include CO2, Nd:YAG, diode, and argon, each with different tissue penetration and interaction characteristics. Some devices deliver both energies in a coordinated fashion, enabling rapid cutting with simultaneous or staged coagulation.

Applications of laserelectrosurgical techniques span dermatology, otolaryngology, gynecology, urology, and various general surgery procedures. They are used for incisions, precise dissection, ablation of lesions, vaporization of superficial tumors, and management of bleeding. The choice of modality depends on desired tissue effect, target depth, and the need to minimize thermal spread.

Advantages of laserelectrosurgical approaches include enhanced precision, improved hemostasis, reduced intraoperative bleeding, and potentially faster recovery with less postoperative edema and scarring in select tissues. Limitations include higher equipment costs, a steeper learning curve, and the need for specialized safety protocols. Potential risks involve unintended thermal injury to adjacent structures, plume exposure, and fire hazards in oxygen-rich environments.

Safety and regulatory considerations emphasize eye protection, smoke plume evacuation, cautious use in oxygen-rich settings, and adherence to device-specific guidelines. Regulatory clearance and accreditation for devices vary by region, with ongoing training recommended for operators.
