Factors affecting the reduction rate of odontogenic cyst after decompression based on three-dimensional volumetric analysis

Abstract

The purpose of this study is to investigate factors that affect the reduction rate of odontogenic cysts after decompression based on three-dimensional volumetric analysis. The sample consisted of 30 patients who underwent decompression of odontogenic cysts at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Chulalongkorn University, from 2010-2022. Preoperative and postoperative cone beam computed tomography results were collected. Volumetric analysis was performed to evaluate any differences in the reduction rate and percentage reduction in the volume (PRV) of the cystic lesion according to the sex, age, initial volume of the lesion, duration of decompression, location of the lesion, decompression technique, and pathological diagnosis. The correlation between these parameters was analyzed. The degree of association was used with a 95% confidence interval (CI).

The sample consisted of 30 patients who underwent decompression of odontogenic cysts at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Chulalongkorn University, from 2010-2022. Preoperative and postoperative cone beam computed tomography results were collected. Volumetric analysis was performed to evaluate any differences in the reduction rate and percentage reduction in the volume (PRV) of the cystic lesion according to the sex, age, initial volume of the lesion, duration of decompression, location of the lesion, decompression technique, and pathological diagnosis. The correlation between these parameters was analyzed. The degree of association was used with a 95% confidence interval (CI). The results of this study showed that the average duration of decompression was 295 days. There was a statistically significant difference in reduction rates by sex and initial volume. The reduction rate in males (31.25 ± 30.68) is higher than in females (11.76 ± 6.06), 95%CI, (P-value =0.04). In addition, the large initial volume had a higher reduction rate than the small initial volume, 95%CI, (P - value<0.001). The conclusion is that decompression cystic is more effective in males and has a larger initial volume of lesions. Computed tomography simplifies and efficiently measures the changes in cystic volume after decompression. Despite this, given the high economic cost and radiation dose, it should be considered a suitable therapeutic option.
