Abstract

Objective: To evaluate the volumetric changes of odontogenic cysts in the mandible following treatment with the active decompression technique through clinical assessment and computed tomography imaging. Materials and Methods: This case series study involved patients with radiolucent lesions in the mandible treated using the active decompression technique at the National Hospital of Odonto-Stomatology in Ho Chi Minh City. Results: The study included 6 patients (5 males, 1 female) with a mean age of 15.5 years (range: 8 to 30 years). Among the lesions, 4 cases (66.7%) were odontogenic keratocysts (OKC), and 2 cases (33.3%) were dentigerous cysts. Facial swelling was the most common presenting symptom (50%). The mean cyst volume before treatment was 11,522.26 ± 7,422.31 mm³, and after 6 months of active decompression, the mean volume decreased to 1,789.63 ± 1,577.72 mm³, representing an 85.83 ± 7.36% reduction. Conclusion: This study demonstrates that the active decompression technique promotes rapid and effective bone regeneration in mandibular odontogenic cysts in a small patient cohort. However, long-term follow-up studies and comparative research are required to further clarify the role of this technique in the management of odontogenic cysts.
