Some issues Dr. John Marshall Robertson, MD can help you with:

Robotic Surgery

Robotic surgery is a type of minimally invasive surgery, using a tiny opening to get inside the body instead of making a large cut. It uses small tools attached to a thin robotic arm, which is controlled by the surgeon. Robotic surgery may be referred to by the specific kind of robot that is used. The most advanced robot currently in use is called the da Vinci, and surgery using it is sometimes called da Vinci surgery.

There are many benefits to robotic surgery, both for the patient and the surgeon. Robotic surgery allows for more precise movements and increased control during very delicate surgical procedures. This makes performing surgery accurately much easier for surgeons and reduces fatigue. The smaller 'hand' of the robot can enter the body via a much smaller opening, which reduces the risk of infection and scarring and leads to a faster recovery. The robotic hands also contain tiny moveable cameras among their tools, giving surgeons a much closer view of the procedure than would be possible with traditional surgery.

Tracheostomy

Tracheostomy or tracheotomy is a surgical procedure to open an airway in a blocked trachea, or windpipe. A small hole is created in the neck, and a tube is often inserted into the hole to provide support and drainage. The patient can breathe through the hole that is created.

Tracheostomy is performed for a variety of reasons when a bypass to the normal airway is needed. A patient may have an object lodged in their throat or have an injury that damaged their windpipe. They may have cancer or a swelling in their throat that stops air from moving freely. Sometimes tracheostomy is performed to make breathing easier when patients are paralyzed or have trouble coming off a ventilator.

A tracheostomy can be temporary or permanent. A temporary tracheostomy tends to heal over easily when the tube is removed, leaving a small scar. A permanent tracheostomy can make speech difficult at first. It takes time to learn how to use the throat and air in a new way.

Tracheostomy is a fairly simple procedure, but it can make all the difference in a life or death situation.
