Intraoperative and Postoperative Complications Associated With Maxillary Sinus Augmentation

Area of Science:

• Oral and Maxillofacial Surgery
• Periodontology
• Dental Implantology

Background:

• Maxillary sinus lift procedures are vital for posterior maxilla bone augmentation.
• Complication rates vary based on surgical technique, patient, and site factors.

Purpose of the Study:

• To determine the frequency of intraoperative and postoperative complications in external and internal maxillary sinus lift procedures.
• To identify risk factors associated with these complications.

Main Methods:

• Retrospective cohort study involving adult patients undergoing maxillary sinus floor elevation.
• Comparison of internal versus external sinus lift techniques using statistical analyses (chi-squared, t-tests, logistic regression).

Main Results:

• Internal sinus lift (60.4%) showed a significantly lower overall complication rate than the external approach (39.6%).
• 144 subjects included; most were systemically healthy, non-smokers.
• Sinus septa, pathology, and bruxism were noted in a subset of patients.

Conclusions:

• Internal sinus lift procedures are associated with fewer complications than external approaches.
• Emphasizes the importance of meticulous preoperative assessment and judicious technique selection in sinus augmentation surgeries.
