What should you know about coltene electrosurgery?

An electrosurgical unit sends high-frequency electrical energy through a medical instrument. Depending on the setting and tip, the clinician may cut tissue, stop small bleeding vessels, or destroy a superficial lesion. This is a procedure category, not a diagnosis, and the appropriate method depends on what is being treated and where it sits.

For a lesion such as a genital wart, the clinician should first confirm the diagnosis and discuss alternatives. Local anaesthetic may be used. The treated area can be tender, swollen, or crusted while it heals, and the final appearance can vary with depth, location, and individual healing.

Tell the clinician about implanted electrical devices, pregnancy, medicines that affect bleeding, allergies to anaesthetic, and any history of thick scars. Ask whether tissue will be sent for examination when the diagnosis is uncertain. Keep the site clean and follow the dressing, washing, and pain-relief instructions. Avoid friction, picking, and sexual contact until the clinician says healing allows it when the treated area is genital.

An electrosurgical unit and the handpiece are selected for the intended technique. Ask which device will be used and why it is suitable for your lesion.

Contact the clinic for bleeding that does not stop with firm pressure, worsening pain, spreading redness, pus, fever, or wound separation. Seek urgent help for heavy bleeding, faintness, breathing difficulty, or rapidly increasing swelling. A lesion that returns or fails to heal needs reassessment.

What is the diagnosis, which electrosurgical technique will you use, and will a sample be examined? What healing changes are expected, how should I care for the wound, and when can I resume normal activity?
