ABSTRACT
Aim of the study: To determine the effectiveness of minimally invasive treatment of large odontogenic jaw cysts using the decompression technique. Material and methods: The study included 32 patients diagnosed with large maxillary cysts (greater than 3 cm), who were treated using the decompression method. For this purpose, celluloid tubes and self-curing acrylic micro-prostheses were used. The paraclinical examination included cone-beam computed tomography. Bone regeneration was assessed by comparing pre- and postoperative cystic cavity volumes at 6 and 18 months after surgery. Results: The mean preoperative length of the lesions was 3.5 cm (median – 3.1 cm), and at 18 months postoperatively – 2.3 cm (median – 2.1 cm). The mean preoperative width was 2.3 cm (median – 2.2 cm), and at 18 months postoperatively – 1.4 cm (median – 1.3 cm). The mean preoperative depth was 1.6 cm (median – 1.7 cm), and at 18 months postoperatively – 1.0 cm (median – 1.1 cm). The mean preoperative cyst volume was 7.4 cm³ (median – 6.3 cm³), and at 18 months postoperatively – 2.3 cm³ (median – 1.4 cm³). Conclusions: The statistical indicators of bone regeneration efficacy (mean – 5.1 cm³, median – 4.5 cm³, minimum – 0.6 cm³, maximum – 20.1 cm³), along with the dynamic comparison of cyst volume using the nonparametric Wilcoxon test showing a statistically significant difference (z =-4.397; p<0.001), demonstrated high effectiveness of the decompression technique in patients with large maxillary cysts.
