Long-term bone remodeling after definitive decompression for jaw cysts based on a three-dimensional analysis

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Radiology
• Bone Regeneration

Background:

• Jaw cysts are commonly treated with decompression as a preliminary step before enucleation.
• This study investigates long-term bone remodeling following definitive decompression for jaw cysts.

Purpose of the Study:

• To evaluate long-term bone remodeling after definitive decompression for jaw cysts using three-dimensional (3D) analysis.
• To assess the efficacy of definitive decompression as a standalone treatment for jaw cysts.

Main Methods:

• Retrospective analysis of clinical and radiological data from patients with jaw cysts.
• Review of data from patients treated between January 2015 and December 2020 with at least two years of follow-up.
• Three-dimensional (3D) radiological analysis to assess cyst reduction and bone remodeling over time.

Main Results:

• A mean cyst reduction rate of 78% was observed one year after decompression, increasing to 86% at an average of 36.1 months.
• Slow ossification of unossified lesions continued beyond one year post-decompression.
• A low recurrence rate of 5.9% was recorded.

Conclusions:

• Bone remodeling is a prolonged process following jaw cyst decompression.
• Definitive decompression is a suitable treatment option for the majority of patients with jaw cysts.
• Extended follow-up is crucial for monitoring long-term outcomes.
