Electrosurgery was first described in great detail by A.J. McLean, who provided histological analysis and interpretation of the healing process in various animal tissues subjected to electrosurgery [1]. McLean also extensively studied principles regarding current density and heat transfer governing the effects of electrical current on tissue [1]. Since its initial description, electrosurgery ha...

BACKGROUND The purpose of this study was to compare the tissue effects of 3 surgical methods of glossectomy with respect to histopathologic assessment by a pathologist. METHODS The anterior tongue of 30 Sprague-Dawley rats was excised using either a steel scalpel, monopolar electrosurgery, or ultrasonic scalpel (3 groups of 10). Specimens were examined by a pathologist blinded to the surgical...

Electrosurgery is used in the majority of endoscopic therapeutic procedures. An understanding of the fundamental electrosurgical principles and various settings available on electrosurgical units is essential for the safe and effective use of electrosurgery during endoscopy. The aims of these technical guidelines are to: (1) expose physical principles relevant to the understanding of electrosur...

As the use of cardiac implantable electronic devices (CIEDs) such as pacemakers and implantable cardioverter-defibrillators is increasing, management of those device-wearing patients with electrosurgery has attracted growing attention, not only in the area of gastroenterology, but also in other fields, including dermatology and urology. For gastroenterologists, there have been concerns about el...

Women with cervical intraepithelial neoplasia now have a number of treatment options including cold-knife conization, laser ablation, and loop electrosurgery but, all too often, the physician s preference is the determining factor in selection of therapy. This detailed presentation of the advantages and disadvantages of electrosurgery will help the physician to decide whether this procedure tru...

Gingival health and appearance are essential components of an attractive smile. Gingival pigmentation results from melanoblastic activity. ‘Black gums’ are common esthetic problem particularly in patients who have a very high smile line (gummy smile). Different treatment modalities have been reported for depigmentation of gingiva such as bur abrasion, scraping, partial thickness flap, cryothera...
