Abstract

Introduction: Complications arising from the use of non-biodegradable substances in aesthetic procedures represent an increasing challenge in clinical practice. This paper describes two clinical cases of late-onset inflammatory reactions associated with the injection of permanent substances into the face.

Methods: Patients were treated with optical fiber endolaser using two distinct laser systems: the Nd:YAG 1440 nm (LipoAI DEKA) and the SmartFiber LMG diode laser (1470 nm, 400-micronfiber). Both cases were monitored through clinical photography and ultrasound imaging (pre-, intra-, and post-treatment).

Results: Imaging exams demonstrated significant improvement in tissue architecture, with reduction of encapsulated hyperechoic areas, partial reabsorption of materials, and absence of inflammatory signs. Clinically, edema, asymmetry, and palpebral retraction improved, with satisfactory aesthetic outcomes.

Conclusion: Endolaser with optical fiber proved to be a safe, effective, and minimally invasive therapeutic strategy for managing late complications due to permanent fillers. Combined use of high-resolution imaging and standardized photo documentation reinforces the clinical validity of this technique.
