Segmental resection vs. partial resection on treating solid multicystic ameloblastomas of the jaws – recurrence rates: A systematic review and meta-analysis

BACKGROUND: The aim of the present study was to compare the recurrence rates of solid multicystic ameloblastomas after segmental resection or marginal resection. MATERIAL AND METHODS: PubMed, ScienceDirect, Web of Science, Scopus, Embase were searched for studies published up to July 2022. The gray literature was also searched. Meta-analysis was performed using OpenMeta Software, p< 0.05 considered significant. RESULTS: Among the search, 8 studies met all eligibility criteria. The group that underwent marginal resection was 1.1 times more likely to present recurrence of the lesion compared to the group that underwent segmental resection. There was no statistically significant difference between the two groups (segmental resection and marginal resection) in all eight studies regarding reducing ND (95% Confidence interval, 0.339 – 3.705; heterogeneity: Q value= 3.105; I2= 0%). CONCLUSIONS: The results showed that there was no statistically significant difference between segmental and marginal resection for the treatment of solid multicystic ameloblastomas; however, prospective studies with more rigorous methodological procedures are needed to better compare the surgical techniques.
