The frenulum is a fold of mucous membrane that attaches the lips and cheeks to alveolar mucosa, gingiva, underlying periosteum. High attachment can cause periodontal esthetic problems, such as gingivitis, gingival recession, central diastema which require frenectomy. Frenectomy complete removal frenulum, including its bone, causing wide wound triggering bleeding. A 21-year-old female patient wh...

Argon Plasma Coagulation (APC) is an application of gas discharges in argon in electrosurgery, which is increasingly used especially in endoscopy. The major application fields are haemostasis, tissue devitalization and tissue reduction.This review describes the physics and technology of electrosurgery and APC. Some characteristics of the argon discharge are shown and discussed, and thermal effe...

EDUCATIONAL OBJECTIVE At the conclusion of this presentation, the participants should be able to describe the tissue effects of steel scalpel, monopolar electrosurgery, and ultrasonic scalpel glossectomy with respect to histopathologic margin assessment in a rat model. OBJECTIVES Histopathologic margin assessment is important in guiding treatment and determining prognosis for squamous cell ca...

With the development of endoscopic surgery, new hazards of high-frequency (HF) electrosurgery have been recognized. The potential risks of monopolar electrosurgery, the limitations of bipolar technique, and the need to reduce instrument interchange have favored the use of ultrasonic technology, which becomes more and more popular. This work aims at presenting the main features of the currently ...

OBJECTIVE To introduce and evaluate the safety of a novel dual-sided electrosurgery handpiece design for simultaneous tissue cutting and coagulation. METHODS We designed a prototype double-sided handpiece allowing automatic switching between two electrodes with a simple handpiece flip. The concept of the system as a surgical instrument was assessed by an animal experiment. RESULTS The skin ...

Background. Surgery is sometimes required for the management of tubal ectopic pregnancies. Historically, surgeons used electrosurgery to obtain hemostasis. Topical hemostatic sealants, such as FloSeal, may decrease the reliance on electrosurgery and reduce thermal injury to the tissue. Case. A 33-year-old G1 P0 received methotrexate for a right tubal pregnancy. The patient became symptomatic si...

Electrosurgery uses electricity to remove tissue, coagulate bleeding, or destroy tumors. Modern units, first developed for application in neurosurgery, are now available in office models that are most commonly used by the family physician for cutaneous surgery. Electrosurgery can accomplish cutting, coagulation, desiccation, and fulguration. Electrosurgical equipment for the office is relativel...

abstract appendicitis after age 40 is unusual, and appendicitis two days after laparoscopic hysterectomy is very rare and has not been reported to date. we describe a 44-year-old woman who had abdominal pain two days after laparoscopic hysterectomy. the pathology report indicated early appendicitis and the pain disappeared after appendectomy. in our opinion, the cause of appendicitis may have b...
