| Objective To analyze the clinical efficacy of fenestration decompression, curettage, guided bone regeneration (GBR), and simple curettage for odontogenic cysts. Methods Sixty patients with odontogenic jaw cysts who were hospitalized in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Anhui Medical University from Aug 2016 to Aug 2017 were selected as subjects. According to different surgical methods, the patients were divided into simple treatment group (group A, control group, 28 cases), curettage + GBR group (group B, 20 cases), and fenestration decompression group (group C, 12 cases). The average operation time, postoperative complication rate, recurrence rate and the percentage reduction of mean cyst volume 3, 6, 9 and 12 months after operation were compared and analyzed statistically. Results The average operation time was lower in group C than that in group A and B, and the difference was statistically significant (P<0.05). There was no significant difference in postoperative complication rate and recurrence rate between 12 months and 6 months after operation among the three groups (P>0.05). The percentage of average cyst shrinkage in group B was greater than that in group A and C in postoperative 3 and 6 months, and the difference was statistically significant (P<0.05). The average cyst shrinkage percentage in group C was greater than that in group A and B in postoperative 9 and 12 months, and the difference was statistically significant (P<0.05). Conclusion Compared with simple curettage and scaling + guided bone regeneration (GBR), fenestration decompression is a minimally invasive, safe and effective treatment for odontogenic jaw cysts. |
