Neonatal mandibular fractures: a scoping review.

While uncommon, trauma-induced fractures to the neonatal mandible require unique consideration. A scoping review of neonatal mandibular fractures (NMF) was performed, in accordance with the PRISMA-ScR guidelines. The PubMed, Embase, Cochrane Library, Scopus, and Web of Science databases were comprehensively searched, covering the period 1990 to March 2025. All studies that reported NMF (age <28 days) were considered eligible. Due to the nature of the studies found, only a descriptive analysis was performed. Seven articles reporting seven cases of NMF were included. Four cases were birth trauma-induced; two of which were associated with forceps delivery and three were associated with an abnormal foetal position during labour. Various treatment modalities, complications, and durations of follow-up were reported. Open reduction was performed in four cases (no fixation, suture fixation, wire fixation, plate and screw fixation performed in one case each) and closed reduction in three (acrylic splint and circummandibular wiring in two, circummandibular wiring alone in one). More studies are needed to explore the association between NMF and birth trauma due to delivery methods and foetal position. Moreover, long term-follow up is required to establish possible implications of NMF and its management on the development of the dentition and facial growth.
