Laser Complications

Laser technology represents a relatively recent addition to the array of devices employed in surgical practice. The field of medical laser applications continues to evolve, with the introduction of new devices and the expansion of indications for laser therapy. According to a publication by StatPearls on the NCBI platform, therapeutic lasers find common use in five distinct areas: vascular coagulation, pigment ablation, facial rejuvenation, tissue cutting or ablation, and hair removal.
In general, the potential complications arising from laser surgery can be mitigated through a combination of technique, careful patient selection, and appropriate device usage. Adverse outcomes such as burns, scarring, dyspigmentation, injury, and infection can result from various types of laser therapy. These complications often stem from a concept known as selective photothermolysis and, in certain instances, can be leveraged to the advantage of the clinician, such as in the reduction of hyperpigmentation in conditions like melasma.
To minimize the risk of complications from excessive thermal injury, many laser systems employ pulse durations that are shorter than the thermal relaxation time of the target tissue. The objective of selective photothermolysis is to deliver precisely the right amount of energy to eliminate the chromophore without harming the surrounding tissue. Both hyperpigmentation and hypopigmentation are relatively common complications following laser treatments, with hyperpigmentation occurring more frequently. Darker-skinned individuals face a higher risk of dyspigmentation. For further information on clinically significant complications, please refer to the provided link.
