Comparative Clinical Evaluation of 450 nm and 980 nm Laser Wavelengths for Safety and Efficacy in ENT Treatment via Laser Ablation

MesicTM (Meril Medical Innovations Pvt. Ltd.,Vapi, Gujarat, India ) Laser ablation as per International Organization for Standardization ISO 13485 user performance criteria. It has become a very useful method of ENT surgery because of its precision and minimally invasive nature. From the most widely used diode lasers, both the 450 nm (blue light) and 980 nm (near-infrared) wavelengths MesicTM laser have their own specific benefits, which are to a great extent based on how different tissues absorb these wavelengths. These differences affect thesurgeon’s capacity for precision, bleeding control, thermal effect management and the way patient recover from surgery. Objective: The main goal of this research was to assess surgical results in ENT/otolaryngology operations conducted with 450 nm and 980 nm diode lasers. The research particularly focused on evaluating surgical accuracy, the healing process, the degree of thermal tissue damage, and the efficacy of hemostasis obtained with each laser wavelength. Methods: Five ENT cases were treated with diode lasers of 450 nm and 980 nm wavelengths. Laser- assisted therapy was chosen on the basis of pathology, and parameters were tuned to achieve coagulation, carbonization, vapourization or precision ablation with minimal thermal injury to check postoperative healing speed and quality, and overall surgical efficacy. The treatment was done with 400 μm bare fiber optic in continuous mode. Postoperative management involved clinical monitoring, pharmacological support, and planned follow-ups to determine recovery, relief of symptoms, and recurrence of different otolaryngology. Results: The 450 nm laser was more precise in surgery, induced less thermal damage to neighboring tissues, and facilitated more rapid healing, and was particularly applicable for precise soft tissue procedures. The 980 nm laser, on the other hand, offered more force and penetration, and was more suitable coagulation force and penetration, and was more suitable for treating vascular lesions and excising greater volumes of tissue, although it produced more thermal effects. Conclusion: Both MesicTM Laser wavelengths are valuable instruments in ENT surgery, but use must be determined by surgical requirements. 450 nm is best suited for delicate, subtle work and quick patient recovery, whereas 980 nm works better with strong hemostasis and more vascular or deeper tissues.
