Biopsy is the act of obtaining small piece of tissue from a lesion. This piece of tissue serves as a representative sample and determines if a lesion is normal, dysplasia, or cancer.
Biopsy of the throat traditionally has been performed in the operating room under general anesthesia. However, with improvements in technology, throat biopsies can be performed with a patient awake in an examination room.
Procedures performed in office date back to the 19th century. This is a diagram illustrating removal of a polyp on a patient who is awake. The surgeon is using the reflectin of a mirror to guide manipulation of the surgical instruments. Now, with the aid of high defintion cameras and tool, procedures can be performed in the office, recorded, and viewed without need for an IV or sedation.
