Various energy devices had been used in thyroid surgery. Aim of study is to develop canine model for recurrent laryngeal nerve injury by harmonic scalpel and to evaluate feasibility of using this model for evaluating the safety use of harmonic scalpel during thyroid surgery. Nine dogs were divided into 3 groups according to distance between harmonic scalpel application and recurrent laryngeal n...

Objective: To determine whether harmonic scalpel has any advantage over monopolar diathermy tonsillectomy or not in terms of blood loss, duration surgery, pain scores and slough separation time. Study Design: Double Blind Cross Sectional study. Setting: Faisalabad Medical University Affiliated Institutions. Period: April 2022 to September 2022. Material & Methods: Seventy patients were sele...

BACKGROUND Despite their safety and effectiveness in thyroid surgery, the previous harmonic scalpel instruments are considered large and cumbersome by several surgeons. An innovative technical improvement of the device has been made available since 2008. The objective of this study was to compare the results of total thyroidectomy using the new harmonic scalpel (FOCUS) with that with the previo...

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: To determine whether harmonic scalpel has any advantage over Ligasure tonsillectomy or not in terms of blood loss, duration surgery, pain scores and slough separation time. Study Design: Double Blind Cross Sectional study. Setting: Faisalabad Medical University Affiliated Institutions. Period: January to June 2022. Material & Methods: Seventy patients total were selected divided ...

Electrocautery has a potential risk of serious pacemaker dysfunction in patients with implanted pacemaker. Here we present the safe and efficient use of ultrasonic scalpel (Harmonic scalpel) for the first time in a patient with implanted pacemaker undergoing open-heart reoperation. q 2002 Elsevier Science B.V.

Total laparoscopic hysterectomy (TLH) is the complete hysterectomy including transection of the uterine vessels and opening/closure of the vaginal vault performed laparoscopically. This procedure can be performed as an alternative to total abdominal hysterectomy in many cases. We previously found use of the harmonic scalpel to be extremely helpful in performing laparoscopically assisted vaginal...

We present the first case of a head and neck oncological procedure accomplished in a Jehovah's Witness using the Ultracision Harmonic Scalpel (Ethicon, Cincinnati, OH). Jehovah's Witnesses present a serious challenge to the head and neck cancer surgeon due to their refusal to accept transfusion of any blood products. However, our experience reinforces the view that surgical management of head a...

UNLABELLED Ultrasound harmonic scalpel has been recently introduced in otorhinolaryngological procedures. AIM to assess macro and microscopic evolution of the healing process of wounds created in the jugal mucosa of rats by the use of ultrasound scalpel. METHOD we used 30 Wistar rats in which we made mucosal incisions on the right jugal mucosa with the ultrasound harmonic scalpel (USHS) and...

Our previous study in CHEST (November 1997)1 reported that there are detectable and increased levels of cytotoxic eosinophil cationic protein (ECP) in the BAL fluid of lung transplant patients with acute allograft rejection, bacterial infection, or cytomegalovirus disease, compared with well, disease-free lung transplant recipients. One possible mecha¬ nism of the activation of eosinophils duri...
