Laser Surgery | Ear, Nose and Throat Lectures | Medical Student Videos | V-Learning™

The key element of this sqadia.com medical video lecture is laser surgery. Starting with the principle of laser, the types of lasers, properties, and effects of lasers also come under debate. Operational parameters of lasers are pursued along with the clinical effects of laser therapy and clinical applications of individual lasers. Lastly, a detailed explanation is given of laser safety precautions. ▬ 📌 Chapters 0:00 Introduction 0:07 Laser Surgery 1:32 Principle of Laser 5:08 Types of Laser 6:53 Effect of Laser on Tissues 10:59 Zones of Tissue Damage ▬ 📌 Properties of Laser The properties and effects of lasers include photothermal, photoacoustic, photochemical, and photodissociation. Then visible lasers are considered whose wavelength is about 400-700nm. Invisible lasers have two zones i.e. ultraviolet zone and infrared zone. Lastly, lasers for use in ear surgery are comprehensively discussed. ▬ 📌 Operational Parameters of Lasers The wavelength of the laser, exposure time, power density, and fluence or radiant exposure are operational parameters of lasers. Power delivered per unit area of spot size and measured in Watts/cm2 is defined as power density. Continuous mode, pulsed mode, and Q-switched mode are three modes reported in succession. ▬ 📌 Laser in Medicine Initially, Dr. Saima Mushtaq was notified about the clinical effects of laser therapy. After that, clinical applications of individual lasers are deliberated in detail. Argon Laser is easily transmitted through clear fluids and used in haemangioma, and telangiectasias. Likewise, the use of the KTP laser is highlighted. Then the light is shed on the use of Nd: YAG in the eye and urinary bladder, turbinectomy. Moving onward, the use of CO2 laser and diode laser is discussed. ▬ 📌 Laser Safety Precautions Education of the staff, protection of eyes and skin, and evacuation of smoke are the safety precautions in the use of lasers. Some other precautions in the use of lasers include displaying a sign outside OT i.e. ‘’lasers in use’’. After that principle of photodynamic therapy is discussed in which a photosensitizing agent is injected. Photosensitizing agents are intravenous and topical sensitizers. ▬ 🎬 5500+ sqadia.com Medical Videos ▬▬▬▬▬▬▬▬▬▬ 👩🏻‍⚕️ Accessible Medical Student Education 24/7/365 💡 Simplifying Medical Learning 💪 Study Hard, Dream Big, Achieve More
