CO2 laser is the standard type of laser for the transoral endoscopic laryngeal surgeries. Diode laser devices have the advantage of being relatively less expensive, lighter in weight and smaller than most other medical lasers. They require less maintenance and can be portable. They have the advantage over the CO2 laser of being readily delivered through fibers allowing easy use with endoscope to reach subglottic and tracheal lesions when needed. 21,22,29-31,35,37,200
CO2 laser produces invisible light in the infrared spectrum with a wavelength of 10.6 microns, which is readily absorbed by water in the tissues. It has a limited penetration of 0.1 mm. Diode laser devices on the other hand can produce light at different wavelengths, commonly between

The 980 nm diode laser has good water absorption. 31
The advantages of laser excisions are that the procedures are minimally invasive, time saving and recovery is potentially faster. The specific advantage of the diode laser is that it is an economic contact laser delivered via a fine glass fiber. Like other fiber optically delivered lasers, this allows the surgeon to hold the fiber in a pencil-like holder (or guidance instrument) and manipulate the fiber tip accurately. 21,188
Surgeon can achieve great accuracy with a hand-held fiber carrier and rigid endoscope to visualize the treatment area. The fiber tip can be directed ‘around corners’ and into lesions providing a much easier manipulated laser than the commonly used CO2 laser, delivered in a straight line via a micromanipulator. 21
In their invitro study on oral soft tissues Goharkhay et al. found that Incision depth and width correlated strongly with average powers, but not with laser parameters or the used tips in the range between 0.5–4.5 W. 36
During our review of literature, we found only few studies on the use of diode laser in laryngeal surgery in humans.

Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is present in the atmosphere only in small quantities (.03% by vol.)

Laser therapy has been accepted widely by the general public and the medical professionals for its extensive benefits. This therapy precisely targets the affected area, minimizes the use of general anesthesia, encourages shorter hospital stay and improves the patient outcomes. These benefits have lead to its increased use and importance worldwide.
After the treatment and procedure is complete, patients leave with healthier, more beautiful teeth, giving them the confidence to ask someone out on a date or the confidence to smile on an important job interview. Dentistry is and has been for centuries, an important aspect of people’s ...
Lasers. Your cosmetic dental office uses cutting edge dental advanced lasers. By using lasers, your teeth can be whitened. If you are having a smile makeover, a laser might be used to lift and contour gum lines.
The curcumin (69±8.7), laser (85±12), and laser + curcumin (88 ±7.9) treated groups significantly enhanced wound closure, compared to the control group (139.8 ±20.2), (One-way ANOVA, LSD test for all groups, p=0.000). We have observed that the curcumin treated group had significantly enhanced wound closure, compared to the l aser + Curcumin group ( LSD test, p=0.033)(Figure2).
It allows surgeons to view problems within the body without making large incisions. An endoscope is inserted through a small cut, or opening. An endoscope is a flexible tube with a camera attached to it to allow the surgeon to see internal organs. Scissors or tongs can be added to the endoscope to operate or remove tissue. Endoscopy has a lower risk of bleeding and infection than open surgery. It can come with rare complications such as: fever, damage to internal organs, and chest pain. The risks depend on the location of the procedure and the overall condition of the patient. Endoscopies fall into categories based on where they are located on the body (5).

Jajou, I questioned the maintenance of his career. What I acquired was that dental practices all vary and this question does not have one general answer. Dr. Jajou currently owns his own practice, which means he his in charge of his office and pays his employees making his salary higher than common dentists. Professional organizations and conferences are not important in the overall outlook of dentistry. On the other hand, Dr. Jajou had plenty to say about the technology used in dentists’ offices. Digital dentistry, or the use of dental technologies, involves lasers, digital scanners, and x-ray machines. However, only dental laboratory technicians use this expert machinery. Dentists use drills, mouth mirrors, probes, forceps, brushes, and scalpels on patients. Later, I asked why he is excessively passionate about oral health from seeing how captivated he is to answer my questions. In the same manner he responds describing how oral health is a huge part of overall health because plaque can affect can cause heart problems and other major health issues beyond your
...y within a medical setting has stepped away from the shadows and into a brighter future with the development of the da Vinci Surgical System in the medical world. Before the surgical robot, doctors or surgeons would have had to make several incisions to their patient’s body, which would cause the patients recovery to be elongated and possibly painful. The da Vinci Surgical System allows surgeons to make smaller, less visible incisions to the patient’s body and have a better precision during the procedure. Throughout several years, surgeons relied on their typical laparoscopic surgery to be able to provide patients with the procedures that required them to make large incisions through the patient’s abdomen. Nowadays, surgeons and their patients can have a sigh of relief because the surgical robot provides surgeons with the precision that they long strived for.
LASIK eye surgery, also called, laser-assisted in-situ kerkatolmileusis, is a procedure which corrects vision problems and eliminates the need for glasses or contact lenses. It’s a type of eye surgery that changes the shape of the cornea using a laser. With LASIK eye surgery, the main goal is to “bend light rays to focus more precisely on the patient’s retina” and to produce clearer and sharper vision.
Lasers (The word laser is an acronym for light amplification by stimulated emission of radiation.) lasers were first introduced in 1960, The first successfully optical laser constructed by Maiman (1960), was a ruby crystal surrounded by a helicoilal flash tube enclosed within a polished aluminum cylindrical cavity cooled by forced air. The ruby cylinder forms a Fabry-Perot cavity by optically polishing the ends to be parallel to within a third of a wavelength of light. Each end was coated with evaporated silver; one end was made less reflective to allow some radiation to escape as a beam was produced. Initially the laser was named the invention looking for a job. Photo-pumped by a fast discharge flash-lamp, the first ruby lasers operated in pulsed mode for reasons of heat dissipation and the need for high pumping powers. Nelson and Boyle (1962) constructed a continuous lasing ruby by replacing the flash lamp with an arc lamp.(1) Today lasers are much like those of the early ones and they are widely used in many fields, their uses are wide spread, From fusion physics to the DVD player these are common places where lasers are used. Medicine and surgery are no exceptions from skin resurfacing to eye surgery to correct vision. With the development of lasers Physicians have been able to provide treatment for a large number of medical disorders. Medical lasers have made it possible to treat conditions, which were previously untreatable or difficult to treat. To make the most of the laser technology physicians must maintain a up to date understanding of laser systems and conditions for which each can be applied .To achieve these goals the basic terminology and fundamentals of laser-tissue interaction is needed.
As you can see lasers are a very useful and important tool which is why I have
Cutting: A laser is also great for cutting objects. It can get to those hard to reach places by the use of mirrors to bend the beam of light. It also is strong enough to cut through solid steel. A laser never damages the surface of the object because it never touches it. Lasers have been
