Abstract:
Management of vascular malformations is multimodal with documented role of surgical resection in specific facets of this condition. Surgical resection of these lesions is technically challenging owing to diffuse and relatively ill-defined extent with involvement of multiple tissue planes limitation of access and excessive intra-operative bleeding. An observational study was conducted in 24 cases taken up for surgical resection of vascular malformations. The cases were divided into two groups based on the hemostasis technique used: Group A: Harmonic shears (n = 12) (Ethicon Inc. Somerville, New Jersey, United States). Group B: Electrosurgery (monopolar/bipolar) with standard knot tying (n = 12). We conclude that use of harmonic scalpel in surgical resection causes less parallel tissue damage, secures haemostasis promptly, does not impede vision and aids surgical dissection thereby significantly reducing the operative time and improving the surgical outcome, typically in large vascular malformations of head and neck region.

Harmonic Mean
Take the example of the speed of a car, which is the measure of the rate of distance traveled. If the vehicle traverses the same distance back-and-forth, its average speed equals the total distance traveled divided by the total time taken. However, if the car moves with varying speeds, then the arithmetic mean is more skewed...
