Abstract

Abstract: PURPOSE: To explore the differences in the prognosis of two different types of decompression procedures for treating large mandibular odontogenic cysts. METHODS: This retrospective cohort study included 93 patients with large mandibular odontogenic cysts, and divided into wall removal group(51 cases) and wall retaining group (42 cases) according to different methods of decompression. Cyst area, volume, HU values and cyst density were compared. The results were analyzed using Prism 7.0 software. RESULTS: After 1 year, the wall removal group was not inferior to the wall retaining group in terms of cyst area, cyst volume, and the difference between the HU values of the original cyst region and the normal mandible. In subgroup analysis, there was no significant difference between the two groups in percentage of patients in whom the cystic area was reduced by 90% after 1 year. However, changes in HU values in the wall removal group were significantly better than those in the wall retaining group. More importantly, patients underwent only one operation in wall removal group if there was no recurrence, which improved the quality of life and reduced the financial burden. CONCLUSIONS: The results suggest that cyst wall removal group showed better results than cyst wall retaining group in large mandibular odontogenic cysts.
