Vessel sealing system uvulopalatoplasty (VSSU) is a new technique for uvulopalatoplasty using a special biclamp forceps for better hemostasis control. Vessel sealing system (VSS) is a bipolar vascular sealing system, with integrated active feedback control. The tissue is grasped and compressed by the handpiece. After the instrument is removed, the seal is visible as a semitransparent window, which can safely be divided. Uvular tip is grasped with an Allis clamp and retracted back toward the soft palate. Excision of the uvula and the redundant part of soft palate is performed by the VSS handpiece. VSS is also used for hemostasis.
Uvulopalatal flap (UPF) is a standard uvulopalatoplasty technique. Uvulopalatal flap is usually performed as described originally by Powell et al. The soft palate was injected with 5 to 10 milliliters of 1% lidocaine with epinephrine solution. The mucosa, submucosa with glands, and fat on the lingual surface of the uvula and soft palate were removed with a scalpel. Bleeding was controlled with bipolar electrocoagulation. The uvular tip was amputated, and reflected back toward the soft palate, and fixated into its new position with multiple sutures of 3-0 chromic catgut.
