Summary
Transnasal endoscopic surgery effectively treats odontogenic maxillary cysts extending into the sinus. This minimally invasive approach preserves teeth and shows no recurrence in a 5-year follow-up.
Area of Science:
- Otorhinolaryngology
- Oral and Maxillofacial Surgery
- Endoscopic Sinus Surgery
Background:
- Odontogenic maxillary cysts can extend into the maxillary sinus, requiring surgical intervention.
- Conventional dental approaches may be invasive and compromise tooth preservation.
Purpose of the Study:
- To evaluate the effectiveness and usefulness of transnasal endoscopic surgery for odontogenic maxillary cysts.
- To assess the minimally invasive nature and tooth preservation potential of this technique.
Main Methods:
- Transnasal endoscopic surgery was performed on 13 patients with odontogenic maxillary cysts extending to the maxillary sinus.
- The procedure involved accessing the cyst via the inferior nasal meatus and removing the cyst wall under endoscopic guidance.
Main Results:
- Complete cyst wall resection was achieved in 8/10 radicular cysts and 3/3 dentigerous cysts.
- Affected teeth were preserved in 7/10 patients with radicular cysts and 1/3 with dentigerous cysts.
- No complications or recurrences were observed during a mean follow-up of 42 months.
Conclusions:
- Endoscopic transnasal surgery is a less invasive alternative to conventional dental approaches for odontogenic maxillary cysts.
- This technique is simple, highly effective, and facilitates tooth preservation.
