Summary
Medial maxillary fractures are a unique nasomaxillary buttress fracture type. They involve specific facial bones and present distinct symptoms, warranting separate classification and tailored surgical approaches.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Trauma Surgery
Background:
- Medial maxillary fractures are a distinct nasomaxillary buttress fracture.
- They involve the piriform aperture, maxillary frontal process, and infraorbital rim.
- This study defines medial maxillary fractures as a unique facial bone fracture type.
Purpose of the Study:
- To define medial maxillary fractures as a unique entity.
- To highlight their specific anatomical involvement and clinical presentation.
- To establish a basis for their distinct classification.
Main Methods:
- Retrospective analysis of eight patients with medial maxillary fractures.
- Preoperative evaluation using 3D and multi-dimensional CT scans.
- Surgical treatment with oral approach, sometimes combined with subciliary approach.
Main Results:
- Seven males and one female (mean age 17.5 years) were treated.
- Common injury mechanisms included interpersonal and small object impacts.
- Patients presented with epistaxis, infraorbital nerve hypoaesthesia, nasal deformities, and/or diplopia.
Conclusions:
- Medial maxillary fractures affect the maxilla, lacrimal, ethmoid, and/or nasal bones.
- They differ from nasoethmoid orbital fractures in the bones involved.
- Classification as a unique fracture type is supported by affected bones, symptoms, and surgical approaches.
