Prevalence of maxillary sinus septa and its impact on sinus augmentation procedures for implant placement

The prevalence, classification and clinical significance of sinus septa and their impact on surgical procedures is of interest. A cross-sectional study involving 30 patients assessed maxillary sinus septa using CBCT imaging. Septa were classified into primary and secondary types and surgical difficulty, membrane perforation and implant success were recorded. Sinus septa are prevalent and significantly affect the difficulty of sinus augmentation and the risk of membrane perforation. Preoperative CBCT evaluation and careful planning are critical for successful outcomes.
