, Federica Veneri b, Luca Losi a, Johanna Chester c, Ugo Consolo aHighlights |
• | Marsupialization cannot be considered definitive therapy for large jaw cysts. |
• | Optimal time to enucleation of large jaw cysts is 8 months after marsupialization. |
• | Time to CBCT follow-up is the only variable influencing cyst volume reduction. |
• | Cyst volume reduction is assessed by semi-automatic segmentation algorithm. |
Abstract |
Objectives |
Optimal time to enucleation following marsupialization of large odontogenic mandibular cysts is undefined. We aim to assess volume reduction throughout follow-up, to indicate optimal time to enucleation. Secondary objectives include the identification of factors influencing cyst reduction.
Study design |
We retrospectively enrolled 15 patients with mandibular cysts of different histological types treated with marsupialization at our center between 2018 and 2022. Cyst volume was assessed with cone-beam computed tomography (CBCT) and a semi-automatic segmentation algorithm, at baseline and between 6 and 8 months post marsupialization.
Results |
The overall mean cyst volume reduction percent (VR%) was 57.7 % or 0.2 % per day. VR% at 8 months was significantly higher than those assessed at 6 and 7 months (67.1% vs 47.1 %, p = 0.003). Time to CBCT was the only independent variable influencing cyst VR%.
Conclusion |
Our study proves that the optimal time to enucleation for mandibular cyst is 8 months, independent of histological cyst type, patient age, baseline cyst volume and the number of pre-operative residual bone walls.
