20.500.12556/DiRROS-29503 Open reduction and internal fixation of paediatric maxillozygomatic complex fractures an 11-year multicentric retrospective study Background/aim: Paediatric maxillozygomatic complex (MZC) fractures are uncommon, and there is a scarcity of data regarding their surgical treatment. The aim of this study was to analyse choices and outcomes of open reduction and internal fixation (ORIF) for MZC fractures among 14 maxillofacial centers around the world. Materials and Methods: This multicentric retrospective observational study included patients ≤16 years of age with quadripod MZC fractures treated with ORIF from January 2011 and December 2022. The following data were collected: age, gender, dentition stage (deciduous, mixed, and permanent), cause of injury, type of fracture, surgical approach, site of osteosynthesis (infraorbital rim, zygomaticomaxillary buttress, frontozygomatic, and zygomaticotemporal sutures), material (titanium or resorbable) and number of plates used, and outcome. The minimum follow-up was 6 months. Statistical analyses were performed with Fisher's exact test or chi-squared test, as appropriate. Results: Sixty-four patients (mean age, 12.3 years) with quadripod MZC fractures were included. Seventy-two percent of patients received a single-point fixation. The zygomaticomaxillary buttress was the most common site for fixation, both in singlepoint and two-point fixation schemes, especially in combination with the frontozygomatic suture. Increasing age was associated with a higher rate of plate removal (p< .001). Postoperative complications included 5 (7.8%) cases of wound infections, 2 (3.1%) infraorbital paraesthesia, 1 (1.6%) ectropion. Residual facial asymmetry was found in 5 (7.8%) patients and was not associated with the type of fixation (p> .05). Conclusions: This study highlights the possibility of using ORIF, even with a single point of fixation, for the treatment of displaced quadripod MZC fractures in the paediatric population. The zygomaticomaxillary buttress was the preferred site of fixation and allowed for adequate stabilization with no external scars and a low risk of tooth damage. Future prospective studies with long-term follow-up are needed to establish definitive surgical protocols and clarify the surgical decision-making. adolescent child fracture fixation maxillary fractures zygomatic fractures otroci zlomi čeljusti fiksacija zloma true false true Angleški jezik Slovenski jezik Neznano 2026-05-22 10:15:15 2026-05-22 10:15:16 2026-05-23 04:01:45 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 22. 5. 2026; str. 680-687 issue 6 Vol. 40 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.31 1600-9657 10.1111/edt.12976 279031043 RAZ_Roccia_Fabio_2024.pdf RAZ_Roccia_Fabio_2024.pdf 1 31FEB1A24B462B6B834F5B3F26EBF563 632c76e80217e0eb5231f67c3d7933ea406760f579e09ca75917a5cd64d3a6f5 871bd3ae-55b6-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44268 https://onlinelibrary.wiley.com/doi/full/10.1111/edt.12976 1 614e1c3b-55b6-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44265 Univerzitetni klinični center Ljubljana 0 0 0
