How Surgeons Evaluate a New Dural Graft: The First Five Cases

Surgeons usually decide about a new dural graft within their first five cases. The first case tests opening, preparation and handling; the next few test sizing, technique and the team’s routine; by the fifth, the surgeon is asking whether they would trust the graft in a difficult case. Careful case selection and quiet, well-prepared support make the difference.

This article describes what typically happens during a surgeon’s early experience with a new collagen dural graft, such as DESU’s DURASHEET or DECOLL, and how a distributor or rep can support it. It is written from the commercial side; clinical decisions always remain with the surgeon and the instructions for use.

Why do the first few cases matter so much?

An experienced surgeon has closed the dura hundreds of times with a familiar graft. Their hands know how it behaves when it is wet, how it drapes over the brain or the thecal sac, how it responds to a needle and how it trims. Any new graft is compared, consciously or not, with that muscle memory.

In the first few cases, differences feel larger than they are. A graft that is slightly stiffer or softer, prepared in a different way or sized differently can feel awkward simply because it is new. If one of those early cases goes badly for avoidable reasons, such as the wrong size or an unfamiliar preparation step, the evaluation may end before the product has had a fair trial.

That is why preparation matters more than persuasion. The rep cannot change how a graft handles, but can make sure that nothing else gets in the way of the surgeon’s judgment.

Which cases should come first?

The best first cases are routine procedures in which the surgeon would normally use a graft anyway, with a defect of predictable size and a straightforward exposure. Examples might include a planned cranial duraplasty or an onlay reinforcement the surgeon performs regularly. These cases let the surgeon focus on the graft rather than on the operation.

Complex cases, such as revision surgery in scarred fields or skull base repairs, are better left until the surgeon and the team are comfortable with the product. Starting with the hardest case puts both the patient pathway and the evaluation under unnecessary pressure.

The rep can help by reviewing the surgeon’s upcoming schedule with the OR coordinator and suggesting which cases might be suitable, while leaving the choice to the surgeon. Spacing the first cases a little apart also helps: it gives time to answer questions and adjust the size plan between cases, instead of repeating the same small problem several days in a row.

What does the surgeon notice in the first case?

The first case is about the basics. The surgeon and scrub team will notice:

• How the package opens and how easily the graft is transferred to the sterile field.
• Preparation according to the instructions for use, and how long it takes.
• How the graft looks and feels when handled with forceps.
• How it trims to shape and whether edges stay clean.
• How it conforms to the surface and stays in position.
• For sutured use, how it responds to the needle and holds a stitch.

With DURASHEET, scrub teams quickly notice that either surface can face the dura, which removes one orientation check. With DECOLL, the focus is on how the membrane lies and overlaps the dural margins in an onlay technique. Neither observation requires the rep to say much; the product speaks for itself if the setup is right.

What changes in cases two to four?

Once the novelty fades, the surgeon begins to calibrate. Sizing becomes more accurate, preparation becomes routine and the scrub team develops its own rhythm. The surgeon starts comparing the graft with the previous product on specific points rather than overall impressions.

This is the stage where questions appear: Would a smaller size have been enough? Is there a better way to trim it for this exposure? Can it be used with the sealant I normally apply? Each question deserves a precise answer. If the rep does not know, the question should go to the manufacturer, and the answer should come back before the next case.

It is also the stage where the team’s opinion forms. Scrub nurses and surgical technologists talk to each other and to other surgeons. Their experience with preparation and handover often influences the department as much as the surgeon’s own view.

Small adjustments made at this stage have a large effect. Moving the graft to a more convenient storage location, updating the preference card with the right size or adding a line about preparation to the scrub team’s notes can turn a hesitant second impression into a confident fourth one.

What decides the fifth case?

By the fifth case, the surgeon is usually asking three questions. Would I use this graft in my difficult cases? Is it reliably available in the sizes I need? Does my team like working with it? If the answers are yes, the surgeon is likely to support adoption at the value analysis committee. If one answer is no, it is worth understanding exactly why.

How should the rep support without getting in the way?

Good support in early cases is almost invisible. A few habits make it work:

• Confirm the case, product and size the day before, and check that the units are in the room.
• Brief the scrub team on preparation and handling according to the instructions for use before the case, not during it.
• Be available, if the hospital allows, but do not interrupt the surgeon during the repair.
• Never offer clinical advice beyond the documented product information.
• Ask for feedback after the case, briefly, when the surgeon has time.

A rep who tries to sell during the case usually loses more than they gain. Surgeons appreciate reps who make the case run smoothly and then listen. The conversation about adoption belongs after the evaluation, when the surgeon has enough experience to judge.

How should feedback be recorded?

A short form after each case is more reliable than a long questionnaire at the end. Record the procedure type, the size used, whether the size was right, the placement technique, handling comments from the surgeon and the scrub team, and an overall impression. Negative comments matter as much as positive ones.

Share the compiled feedback with the manufacturer. DESU designs and manufactures its dural grafts in its own cleanrooms, so handling feedback from real cases reaches the people who make the product. That is useful for the manufacturer and reassuring for the surgeon, who sees that their opinion goes somewhere.

Finally, use the feedback to support the hospital’s decision. A one-page summary for the value analysis committee, based on the surgeon’s own cases, is far more persuasive than any brochure.
