What anatomical structure is crucial to consider during zygomatic implant placement?

The maxillary sinus is a critical anatomical structure to consider during zygomatic implant placement due to its proximity to the proposed implant site. When placing zygomatic implants, which are anchored into the zygomatic bone, it is essential to avoid penetration into the maxillary sinus. This sinus is located above the upper jaw and can be easily violated if the implant is placed too deeply or in an incorrect angle. Such penetration can lead to complications, including sinusitis, infection, and loss of the implant.

Furthermore, understanding the anatomical relationship between the maxillary sinus and zygomatic bone helps clinicians adequately plan the implant position, ensuring stability and proper function of the implant while minimizing surgical risks. This knowledge aids in making informed decisions regarding the angle and depth of the implant placement to avoid complications that arise from unintended sinus involvement.
