Limitations
COMPLICATIONS
Despite being a prospective study, the present study has some limitations. First, there were two surgeons and not only one who performed the operations in both groups. The surgical skills may differ from one to another and may result in less favorable outcomes. Second, the follow-up time was short. In some cases, the follow-up time was 2 months as the parents thought there was no longer a need for more follow-up given that no apparent complications appeared. Thus, further studies with long-term follow-up are needed to detect any late complications. Third, our study was performed in a single center. A multicenter study will be planned to obtain more information and provide more accurate results.
