OBJECTIVE Neck dissection is the most definitive and effective treatment for head and neck cancer. This systematic review aims to compare the efficacy and surgical outcomes of neck dissection between the harmonic scalpel and conventional surgical techniques and conduct a quantitative meta-analysis of the randomized trials. METHODS Randomized controlled trials (RCTs) were identified from the m...

Gingival hyperpigmentation is seen as a genetic trait in some populations and is more appropriately termed physiologic or racial gingival pigmentation; a benign condition, which affects all races. Gingival depigmentation is most often performed as a „patient demanded‟ periodontal plastic surgical procedure; wherein scalpel, laser, electrosurgery, cryosurgery, diamond bur or chemical agents are ...

Tonsillectomy is old surgical procedure that has evolved to a more safe method that has lesser complications with little or no morbidity and mortality. Aim: this was comparative study which compared the old dissection tonsillectomy method and the newer method of tonsillectomy (ultrasonic scalpel and Laser tonsillectomy method). Methodology: Equal number of patients both in age and sexes had con...

BACKGROUND Gold standard treatment for symptomatic gall stones is laparoscopic cholecystectomy (LC). Ultrasonically activated devices have been used for gall bladder dissection in LC. Harmonic scalpel (HS) is the leading ultrasonically cutting coagulation device offering surgeons important benefits. The main aim of our study was to compare the surgical outcomes of LC performed by HS to that per...

BACKGROUND The purpose of this study was to evaluate the effect of the dissection technique on outcomes and complications after a full abdominoplasty, comparing 2 different techniques used to raise the abdominal flap: the steel scalpel and the diathermocoagulation device on coagulation mode. METHODS A prospective study was performed at a single center from January 2009 to December 2011 of pat...

BACKGROUND Monopolar cautery is the most commonly used surgical cutting and hemostatic tool for head and neck surgery. There are newer technologies that are being utilized with the goal of precise cutting, decreasing blood loss, reducing thermal damage, and allowing faster wound healing. Our study compares thermal damage caused by Harmonic scalpel and CO2 laser to cadaveric tongue. METHODS Tw...
