Surgical scissors isn't only a good medical tool for sharp cutting, for blunt dissection you would want to get the proper tips on the surgical scissors by probing, spreading or ranking. For blunt dissection, surgical scissors have an added ability as opposite to a clamp, because switching back & forth from blunt cutting to sharp can be done without switching back & forth your surgical instruments. Blunt cutting spreads apart the layers of tissue. The cementing substance can be either normal areolar tissue, as between fascial layers, or scar tissue from former surgery.

In the blunt dissection of layers bound by scar tissue you will stumble upon hazard where the scar tissue traverses the cut in one of the layers. It's considered risky when the cutting between layers when you have more tensile strength than the bound layers of the adhesions. A scar could bind bowel to fascia or parietal pericardium to the heart with more tensile strength than is present within the bowel or within the myocardium. Blunt dissection in these cases may be unnecessary & result in an unintended enterostomy or entrance into the myocardium. This is why its risky for blunt dissection where you see some old scares come together with natural planes or where dense scar tissue is tougher than the structures it blinds.

Usually when surgeons cut using surgical scissors its in direct view. Blind scissors cutting & blunt dissection can sometimes be of great advantage and may be accurate & secure. Sometimes blind cutting is done in between the tissue planes in the anatomic regions away from such critical structures as big vessels & nerves. To open up a tunnel beneath the dermis, you will want to use the blind surgical scissor dissection method to put in a heterograft when you make an arterial venous fistula.

Blind surgical scissor dissection can also be put to your benefit while performing a breast biopsy through a tiny circumareolar cut. Often it is hard to see the deep side of a breast lump; but, by palpation, when you use a left pointer-giner as a guide, surgical scissors can be used to circumscribe and remove the lump.

While exposing major blood vessels by blunt dissection with scissors, be sure to express caution when performing this, because you could tear small tributaries and braches. If surgical scissors are used to spread parallel to a major vessel, be sure to focus and not make any tearing of side branches; if you spread perpendicular to the great blood vessel; focus your full attention plaques. Both methods, do have setbacks, can be used if the inherent problems are understood.
