Pouch versus non‐pouch technique for repairing the maxillary sinus membrane large perforation in rhesus monkey

This study explored two surgical techniques for repairing large perforations in the sinus membrane during dental procedures, focusing on the bone growth outcome. We compared the "Loma Linda Pouch" technique, which uses absorbable membrane to create a pouch that surrounds the inner surface of the sinus, to a traditional method. We measured various outcomes, including bone height, density, and overall volume, at 1 month and 9 months after surgery. Both techniques showed substantial and ideal bone growth, but the pouch method may help stabilize the bone graft and minimize graft volume loss in the long run. Importantly, both methods led to effective healing without major complications, and our findings showed that the absorbable membrane does not hinder new bone formation. These insights can assist dental professionals in selecting the most effective approach for sinus surgeries, ultimately improving the success of dental implants and enhancing patient outcomes.
