drnewittSpectatorI have been noticing that when I do soft tissue re-contours that I am getting very fine strands of tissue clinging to the end of the laser tip. It reminds me of cotton candy in it’s properties in that it is very fine and seems to almost have a static cling characteristic to it.
I am cutting with a 600u tip, usually with my Delight settings at 10Hz 70mJ, no water. And I stay out of contact with the tissue.
Is this normal or am I getting to close to the tissue etc etc?
I notice the cutting ability of the tip decreases pretty fast when it has all these hairs of tissue glomed onto it.

This would cause scattering of the beam and less efficiency. Does the tissue just cling to the end or the sides also?
Why no water?
If no water, how are you cooling the tissue?

Your findings are normal and not unlike those of myself. Personally when I use the DELight erbium for soft tissue I use the 30 Hz rep rate to acheive smoother ablation. You can stop periodically and cleanse the erbium tip with a water impregnated 2X2 not unlike as if you were applying treatment with a diode fiber. Dr. Schalter’s point regarding cooling of tissue should be well taken, however, I have not personally experienced any untoward effects by using the erbium at this low energy setting without water. A light water spray may be added to reduce “cotton candy” effect.

dkimmelSpectatorAl, Are you seeing any difference in using the watrelase vs the delight on soft tissue? I would expect to see a difference with the ablity to use 30HZ. Also with the Waterlase we can use it in contact mode .75W 11%A/0%W to contour tissue can you do this as well with the Delight.

They appear to work the same although I get smoother soft tissue ablation at the 30 Hz setting. I don’t like to use the erbium tips in contact.

dkimmelSpectatorAllen try 3HZ 6omj with a 400 micro tip for troughing. Stay in contact to slightly out. A good friend said something about being able to do this with the Delight.
