Closed reduction of midline palatal fracture using a palatal acrylic splint and interdental wiring: case report

다국어 초록 (Multilingual Abstract)

Midline palatal fractures compromise maxillary transverse stability and cause oro-nasal communication. We report a successful minimally invasive reconstruction based on AO CMF principles. A 60-year-old male with Le Fort II and midline palatal fractures following a fall exhibited nasal regurgitation. Associated facial fractures were managed conservatively, while the palatal fracture was addressed with a customized acrylic splint fabricated via model-based virtual surgery to restore pre-traumatic occlusion. Intraoperatively, segments were repositioned through manual reduction, followed by intermolar wire ligation and splint fixation. Nasal regurgitation resolved by postoperative day 4. Evaluation at 10 days confirmed anatomical arch width restoration. Stable occlusion was maintained throughout the 6-week splinting period. Closed reduction using customized splints and interdental ligation is an effective, minimally invasive alternative for managing midline palatal fractures, particularly when open reduction is challenging.
