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

## TL;DR

This study shows that maxillary sinus septa are common and can complicate dental implant procedures, emphasizing the need for preoperative imaging and planning.

## Contribution

The study provides new insights into the prevalence and classification of sinus septa and their impact on surgical outcomes.

## Key findings

- Sinus septa were found to be prevalent in the studied population.
- The presence of septa significantly increases surgical difficulty and the risk of membrane perforation.
- Preoperative CBCT imaging is critical for successful implant placement.

## Abstract

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.
