Summary
A rare surgical ciliated cyst developed nine years after maxillary sinus floor augmentation. This highlights the risk of entrapped sinus membrane, even without perforation, potentially preventable by tightly covering the lateral window.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Otorhinolaryngology
Background:
- Maxillary sinus floor augmentation is crucial for dental implants.
- Complications like sinusitis and infection are known.
- Surgical ciliated cysts post-procedure are rarely reported.
Observation:
- A 55-year-old woman developed a cyst 9 years after bilateral maxillary sinus floor augmentation.
- The cyst formed despite no apparent perforation of the Schneiderian membrane during surgery.
- Imaging revealed a well-defined radiolucent lesion in the maxilla.
Findings:
- Enucleation and histological examination confirmed a surgical ciliated cyst.
- The cyst likely arose from Schneiderian membrane entrapped within the grafted bone.
- This occurred without visible perforation or tearing of the membrane.
Implications:
- Entrapped sinus membrane, even without perforation, can lead to surgical ciliated cysts.
- Tightly covering the lateral window during augmentation may prevent cyst development.
- This case underscores the importance of long-term monitoring after sinus augmentation procedures.
