BACKGROUND: Decompression is an effective treatment for jaw cysts. Many studies have reported its effectiveness as a preliminary treatment followed by secondary enucleation. This study aimed to explore long-term bone remodeling after definitive decompression for jaw cysts based on a three-dimensional (3D) analysis.
METHODS: This was a retrospective study. The clinical and radiological data of patients with jaw cysts who underwent decompression and were followed up for two years or more at Peking Union Medical College Hospital between January 2015 and December 2020 were reviewed. The 3D radiological data before and after decompression were analyzed to study the long-term reduction in cysts, especially after one year of decompression.
RESULTS: A total of 17 patients with jaw cysts were included in this study. The radiological data showed a mean reduction rate of 78% one year after decompression. At the final examination, which was 36.1 months after decompression on average, the mean reduction rate was 86%. The unossified lesions could still ossify slowly after one year of decompression. The recurrence rate was 5.9% (1/17).
CONCLUSIONS: Bone remodeling continued for a long time after decompression. Definitive decompression could be an option for most patients with jaw cysts. Long-term follow-up is required.
