New surgical trick may seal sinus holes better
NCT ID NCT07196566
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a two-layer surgical technique to close oroantral fistulas—abnormal openings between the mouth and sinus cavity. Twelve patients will receive the procedure using tissue flaps from the cheek and palate. Researchers will monitor healing, pain, swelling, and whether the fistula returns over three months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgical procedure using buccal and palatal flaps with connective tissue graft
- What this could lead to
- If successful, this technique could offer a more reliable way to close oroantral fistulas, reducing the need for repeat surgeries.
- What could go wrong
- This is a very small study with only 12 patients and no control group. Results may not apply to everyone, and the procedure carries typical surgical risks like infection or pain.
