Conclusions
In general, the event rate of the one-to-two-week postoperative complications analyzed in this systematic review did not differ between the two groups. In light of this observation, and within the limits of this analysis, we can conclude that the use of corticosteroids in the lateral sinus augmentation procedure needs further investigation in order to determine whether or not they have an impact on the post-operative course of lateral MSA. This can only be confirmed or denied through randomized clinical trials with the main purpose of investigating the use of corticosteroids in the lateral maxillary sinus augmentation procedure.
