Plain English summary of protocol
Background and study aims
Recurrent or chronic inflammation of the tonsils (tonsillitis) is currently a global public health issue which can severely impair an individual’s quality of life.
Tonsillectomy is a 3000-year-old operation. Tonsillectomy is a surgical procedure to remove the tonsils. Tonsils are two small glands located in the back of your throat. Although tonsillectomy is performed less often than it once was, it is still among the most common surgical procedures performed in children anywhere in the world. The main indication of tonsillectomy is the recurrent throat infection. Tonsillitis and the need for tonsillectomies are more common in children than adults. However, people of any age can experience trouble with their tonsils and require surgery.
There are several different ways to remove tonsils. Most common method is called “cold knife (steel) dissection.” In this case, your surgeon removes your tonsils with a scalpel. Another common method for tonsillectomy involves burning away the tissues through a process called cauterization, CO2 laser etc. However, like with other surgeries, there are some risks with this procedure: swelling, intraoperational and postoperational bleeding, postoperational pain and delayed healing. Tonsillectomy with Thulium RevoLix laser usage could minimize the listed risks and thus improve the patient’s quality of life after tonsillectomy surgery, as it is surgical laser available for soft tissue surgery which unifies all advantageous properties of existing laser principles in a single unit.
Who can participate?
Adults over 18 years with chronic or recurrent tonsillitis
What does the study involve?
Patients due to have tonsils removed surgically will have the right side tonsils removed using the Thilium RevoLix laser and the left side with the cold steel method. Patients will be followed up for 10 days to assess the difference between the two methods.
What are the possible benefits and risks of participating?
Improved quality of life: Having the tonsils removed, as an adult, can help prevent a recurring sore throat, or tonsillitis (inflammation of the tonsils), that may force you to miss work. By having the tonsils removed, patients should no longer experience uncomfortable symptoms, such as pain and a sore throat related to tonsillitis
Fewer infections: As the tonsils will be removed and general health improved, those who experience tonsillitis caused by bacteria should have fewer infections.
Less use of medication: If patients have fewer tonsillitis infections, they may be prescribed less medication, such as antibiotics. Although antibiotics have many benefits, they kill off good bacteria as well as the bad.
There is no specific risk of operation regarding the technique of the operation. There are standard risks of operation tonsillectomy:
Reactions to anesthetics. Swelling, bleeding during surgery, bleeding during healing, infection.
Where is the study run from?
"Heratsi" #1 Hospital complex (Armenia)
When is the study starting and how long is it expected to run for?
May 2020 to November 2020 (updated 10/07/2020, previously: June 2020)
