Summary
This study introduces a simple technique using a transnasal light wand to accurately locate the maxillary sinus floor and septa during sinus augmentation surgery. This method enhances surgical precision and aids in postoperative graft evaluation.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Anatomical Navigation
Background:
- Accurate localization of the maxillary sinus floor is critical for successful sinus augmentation.
- Intraoperative anatomical identification can be challenging, increasing risks of perforation or inadequate graft placement.
- Existing methods may lack precision or simplicity.
Purpose of the Study:
- To present a straightforward, cost-effective method for intraoperative visualization of the maxillary sinus floor and septa.
- To improve the safety and predictability of sinus augmentation procedures.
- To offer a tool for postoperative assessment of bone graft density.
Main Methods:
- Transnasal illumination of the maxillary sinus using an anesthesia light wand.
- Guided elevation of the lateral maxillary wall based on direct visualization.
- Application of the technique for preoperative planning and postoperative evaluation.
Main Results:
- The described method allows for precise identification of the sinus floor and septa.
- Surgeons can reliably elevate the lateral maxillary wall with reduced risk of overcutting.
- Postoperative assessment of bone graft density is facilitated.
Conclusions:
- This transnasal illumination technique offers a simple, inexpensive, and precise approach to maxillary sinus floor localization.
- It enhances surgical confidence and accuracy during sinus augmentation.
- The method provides a valuable tool for both intraoperative guidance and postoperative graft assessment.
