More info needed on Dr. Sohns piezo tip
Any issue with perforation? How do you maintain the sinus elevation?
perforation management in HPISE
Perforations are rare with the piezo but, when they occur, collagen or CGF or PRF can be placed over it anf then proceed as usual.
If the perforation is large, consider conversion to lateral approach or close and re-appoint if a few weeks as the sinus membrane usually heals thicker after perforation
When perforation occurs at 1st osteotomy site, perform HPISE at 2nd site. Membrane will be elevated from 2nd site to 1st site.
Thank you

Dr. Sohn a question of your Piezo tip
Does the tip itself cut bone or do you insert it after you infacture the sinus?
Is it a constant flow of water or is a burst effect?
The hpise tip itself cuts
The hpise tip itself cuts bone. However, when the sinus floor is especially dense, the round piezo tip cuts faster. After the bony sinus floor is perforated, you can then switch over to the hpise tip to gently enlarge the bony opening and simultaneously lift the membrane.
Is it a constant flow of water or is a burst effect?
It is a constant flow of water. Please see the following video:

Dr. Sohns Piezo tip
Great article but I am wondering if the water pressue can cause a sinus tear?
The thickness of the sinus
The thickness of the sinus membrane varies from patient to patient and membrane tears/perforations are a possibility with any technique. Tears are very infrequent with this technique and more likely to occur if you're too aggressive removing the bony sinus floor and "pop" into the sinus cavity instead of letting the piezo and water do the work. Dr. Sohns has posted some videos of the technique at www.hpise.com. Hope that helps,

Dr. Sohn's Piezo Tip question
Do you find the water pressure is enough to lift the membrane?
Any problem with infusing that volume of water into the sinus?
Do you find the water
Do you find the water pressure is enough to lift the membrane?
Yes
Any problem with infusing that volume of water into the sinus?
No. Sterile saline should be used, though.
Dr. Sohn has some videos posted at www.hpise.com you might be interested in. Thanks,

Piezo Tip: A question for Dr. Maupin
Very nice article Dr. Maupin. So you find this technique to be easier then an osteotome lift? Are there risks? Your opinion is appreciated.
Yes, I think the technique is
Yes, I think the technique is easier than using an osteotome. It is also less traumatic to the patient as there is no banging. The risks are similar to that of any internal sinus lift, although the incidence of membrane perforation should be lower.

Will the tip work for all piezo units?
Piezo tip
To the best of my knowledge, the tip is compatible with Surgybone, Piezosurgery and the UBS unit. Thanks,
