Long‐term stability of sinus complication management

Abstract

Maxillary sinus augmentation shows a low incidence of complications and high clinical success due to favorable biological conditions and typically transient issues. Most complications are intraoperative, such as Schneiderian membrane perforation or hemorrhage, and are often resolved immediately. Postoperative complications, like sinusitis, graft loss, and voice alterations, are less frequent but clinically relevant. This study evaluates the long‐term effects of intraoperative and postoperative complications in maxillary sinus augmentation. A specific classification was used to differentiate these complications, focusing on their impact on bone graft maintenance and dental implant survival. Special attention was given to the progression of sinus inflammatory pathology, from preoperative conditions to acute and chronic sinusitis. While intraoperative complications are generally manageable, they can predispose patients to postoperative issues that affect long‐term outcomes. Sinus membrane perforation emerged as a key intraoperative factor linked to later sinusitis, compromising graft integrity and implant stability. The evolution of sinus inflammation significantly influences the long‐term success of both graft material and implants. Complications in maxillary sinus augmentation, if not properly managed, can have lasting effects. Careful surgical technique and thorough postoperative monitoring are essential to mitigate risks and ensure long‐term success. Recognizing the long‐term impact of these complications is crucial for optimizing outcomes in maxillary sinus augmentation.
