Vessel Sealing System Uvulopalatoplasty Versus Uvulopalatal Flap
The purpose of this study is to compare vessel sealing system uvulopalatoplasty (VSSU) to the traditional uvulopalatal flap (UPF) in the treatment of sleep-disordered breathing with special regard to intraoperative bleeding, operative time, postoperative pain, postoperative hemorrhage and other adverse effects.
Uvulopalatopharyngoplasty is one of the common procedures performed by otolaryngologists to treat sleep-disordered breathing patients who have retropalatal obstruction. Intraoperative bleeding is a significant problem which requires hemostasis and causes prolonged operative time. Several different techniques are used to perform this operation, including cold knife, monopolar cautery, coblation, and radiofrequency. Efficacy in hemostasis and tissue trauma from different operative techniques may result in different operative time and different degrees of morbidity including intraoperative blood loss, postoperative pain, postoperative hemorrhage, and velopharyngeal insufficiency (VPI). The vessel sealing system has been widely used in head and neck surgery because of its effectiveness and safety. It was also found quite effective and safe in tonsillectomy procedures, providing excellent hemostasis and minimal tissue trauma.

Medical and Biotech [MESH] Definitions
Endonucleases that remove 5' DNA sequences from a DNA structure called a DNA flap. The DNA flap structure occurs in double-stranded DNA containing a single-stranded break where the 5' portion of the downstream strand is too long and overlaps the 3' end of the upstream strand. Flap endonucleases cleave the downstream strand of the overlap flap structure precisely after the first base-paired nucleotide, creating a ligatable nick.
Keratomileusis, Laser In Situ
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.
Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.
Keratectomy, Subepithelial, Laser-assisted
A surgical technique to correct REFRACTIVE ERRORS of the EYE, such as MYOPIA and ASTIGMATISM. In this method, a flap of CORNEAL EPITHELIUM is created by exposure of the area to dilute alcohol. The flap is lifted and then replaced after laser ablation of the subepithelial CORNEA.
Rough, noisy breathing during sleep, due to vibration of the uvula and soft palate.
This study was planned to compare vessel sealing system tonsillectomy (VSST) to the traditional cold knife tonsillectomy (CKT) with special regard to intraoperative bleeding, operative tim...
The aim of this trial was to verify the efficiency of a new surgical device (the LigaSure vessels sealing system) in esophagogastric decongestion and splenectomy in patients with portal hy...
Bilateral DIEP flap needs two groups of vessel pedicles. We suppose that the bilateral DIEP flap may survive on one vessel pedicle by means of interconnection of bilateral DIEA. This study...
The aim of this study is to determine the postoperative course including effects on the quality of life following soft palate surgery with radiofrequency knife (RAUP).
Objective: To compare the safety and efficacy of the use of bipolar plasmakinetic vessel sealing (Gyrus Pk) usage versus standard technique when performing total abdominal hysterectomy fo...
Abstract Conclusion: No case of death related to surgery in the form of uvulopalatopharyngoplasty, uvulopalatoplasty or nasal surgery for snoring or sleep apnea has been recorded in Sweden among 4876...
Radiofrequency surgery was introduced to minimize thermal damage to the tissue. A radiofrequency electrode can be used to make cuts in the free edge of the soft palate like those done in laser-assiste...
