Perforation Risk Assessment in Maxillary Sinus Augmentation with Lateral Wall Technique

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Anatomical Risk Assessment

Background:

• Maxillary sinus augmentation is crucial for dental implants in patients with insufficient bone height.
• Sinus membrane perforation during lateral window procedures is a known complication.
• Perforation, while not directly causing implant failure, is linked to postoperative complications.

Purpose of the Study:

• To review anatomical and patient-related risk factors for sinus membrane perforation.
• To propose a novel risk-evaluation system for lateral sinus augmentation.
• To enhance predictability and reduce complications in sinus elevation surgery.

Main Methods:

• Comprehensive review of peer-reviewed journal articles.
• Identification and analysis of factors influencing sinus membrane perforation risk.
• Development of a risk assessment table for pre-surgical evaluation.

Main Results:

• Several anatomical and patient-specific factors contribute to perforation risk.
• A structured risk assessment approach can aid clinical decision-making.
• The proposed system aims to standardize pre-operative risk evaluation.

Conclusions:

• Implementing a pre-surgical risk assessment can improve outcomes in maxillary sinus augmentation.
• Understanding risk factors is key to minimizing complications like membrane perforation.
• The proposed risk table offers a practical tool for clinicians planning sinus lift procedures.
