BACKGROUND The ultrasonic scalpel is a recently introduced device in head and neck surgery. Total thyroidectomy is the most common endocrine procedure performed by surgeons. METHODS This was an open, phase IV, multicenter, randomized controlled trial (RCT) that compared the use of an ultrasonic scalpel with a conventional technique in patients who underwent total thyroidectomy. The outcomes w...
As a surgery attendant passed a scalpel to the surgeon, the surgeon simultaneously reached for it; they bumped hands and the attendant’s left index finger was cut. A physician and nurse completed a c-section and were cleaning the patient. As the nurse reached back for a towel, she was cut by a scalpel held by the OR technician. An attending surgeon was assisting the primary thoracic surgeon wit...
INTRODUCTION: Management of posthemorrhoidectomy pain remains a very unsatisfactory clinical dilemma. Compared with electrocautery and laser, the Harmonic Scalpel ® causes minimal lateral thermal injury during tissue dissection. PURPOSE: The aim of the study was to establish whether decreased lateral thermal injury translated into diminished posthemorrhoidectomy pain. METHODS: A prospective ran...
Gingival hyperpigmentation is believed to be a genetic trait in populations and more appropriately termed physiologic or racial gingival pigmentation condition, which affects all races differently. depigmentation most frequently performed as an esthetic periodontal plastic surgical procedure. There are various procedures like scalpel, laser. Cryosurgery, diamond burs chemical methods have been ...
OBJECTIVE To evaluate the independent relationship of the Shaw scalpel on the development of facial nerve injury in patients undergoing superficial parotidectomy. METHODS A retrospective review of 77 cases between 1991 and 1996. Forty-eight percent of the surgical procedures were performed using the Shaw scalpel, and 52% were performed using a cold knife. To assess whether use of the Shaw sca...
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...
BACKGROUND Despite the common use of conventional electrocautery in modified radical mastectomy for breast cancer, the harmonic scalpel is recently emerging as a dominant surgical instrument for dissection and haemostasis, which is thought to reduce the morbidity, such as seroma and blood loss. But the results of published trials are inconsistent. So we made the meta-analysis to assess the intr...
BACKGROUND Parotidectomy is one of the most commonly performed procedures by otorhinolaryngologists. Traditionally dissection is performed with a combination of a steel scalpel and bipolar cautery; however, starting in the early 2000s, the Harmonic scalpel has provided an alternative method for dissection and hemostasis. The purpose of this study is to compare operative time, blood loss, compli...
background haemorrhoids are cushions of submucosal vascular tissue located in the anal canal starting just distal to the dentate line. haemorrhoidal disease is a common anorectal disorder which has symptoms of bleeding, prolapse, pain, thrombosis, mucus discharge, and pruritus. haemorrhoidectomy is one of most frequently performed anorectal operation worldwide. objectives the aim of this study ...
