introduction : for many years surgical incisions were done by scalpel. nowadays this method has been replaced with electrocautery.each of these methods has their disadvantages and benefits. the purpose of this study is to compare these two methods in midline laparotomy surgeries. methods :  from 2012 until 2013, one hundred patients enter the study, underwent midline laparotomy and were divided...

INTRODUCTION Partial glossectomy is the main treatment for tongue carcinoma. The resection of the tongue, which is a very vascularised tissue, requires a good hemostasis. The advantage of the harmonic scalpel is in combining sectioning and hemostasis in one single instrument, allowing a bloodless dissection of soft tissue. The aim of this prospective study was to evaluate the benefits and risks...

In the field of spinal tumors, intralesional tumor cutting is sometimes inevitable. The purpose of this study was to compare the potential for tumor growth after intralesional cutting by T-saw, Gigli saw, and scalpel. Tumors, prepared by the subcutaneous injection of human HT 1080 fibrosarcoma cells in nude mice, were harvested and cut with a T-saw, Gigli saw, or scalpel. A 3-cm wound was creat...

Background: Thyroid gland is a highly vascular organ. So, doing thyroidectomy requires good hemostasis even for the small blood vessels either through conventional tie technique which time-consuming or use of harmonic scalpel. Objective: To evaluate real benefits Harmonic Scalpel in total thyroidectomies when compared with ligation, terms operative time, postoperative drainage, and complication...

Pigmentation of gingiva is most often a physiologic phenomenon resulting from deposition of endogenous melanin by melanin granules of melanocytes in the epithelium. Although not a medical problem or a disease entity, it is a major concern among young individuals as it hampers esthetics. To restore the ‘pinkness’ of the gums, various techniques such as scalpel method, bur abrasion, electrosurger...

The use of ultrasonically activated scalpel for tissue cutting and coagulation is a potential replacement for electrosurgery, which can be related to different complications. Its working principle is to transform the electric power into the mechanical longitudinal movement of the working part of the instrument, by a piezoelectric transducer situated in the hand piece. Between October 2000 and J...

OBJECTIVE Applicability of harmonic scalpel in lung biopsy was investigated in a randomised single institute study. METHODS Safety of the method, morbidity, drainage duration and in-hospital stays were compared in two randomised groups of patients in which either ultrasonic harmonic scalpel (n:20) or endostapler (n:20) were used for pulmonary biopsies during VATS. RESULTS An advantage of 16...

Arachnoid webs are intradural extramedullary bands of arachnoid tissue that can extend to the pial surface of the spinal cord, causing a focal dorsal indentation of the cord. These webs tend to occur in the upper thoracic spine and may produce a characteristic deformity of the cord that we term the "scalpel sign." We describe 14 patients whose imaging studies demonstrated the scalpel sign. Ten ...
