We consider medial maxillary fractures to be a unique type of nasomaxillary buttress fracture involving the lateral margin of the piriform aperture, the maxillary frontal process and the medial aspect of the infraorbital rim. This article aims to define medial maxillary fractures as a unique type of facial bone fracture.
Eight patients with medial maxillary fractures were treated at our hospital from May 2010 to June 2013. Every patient was preoperatively evaluated using three-dimensional and multidimensional computed tomographic scans and surgically treated.
The subjects were seven men and one woman (mean age: 17.5 years). The common mechanism of injury was interpersonal impact followed by small object impact. All of the patients exhibited epistaxis and hypoaesthesia affecting the maxillary nerve and/or its branches, and some patients also displayed nasal deformities and/or diplopia. An oral approach was employed in every case, and it was combined with a subciliary approach in some cases. Medial maxillary fractures involve the maxilla, lacrimal bone, ethmoid bone and/or nasal bone. The main difference between medial maxillary fractures and nasoethmoid orbital fractures is the bones they affect.
Medial maxillary fractures are a unique type of nasomaxillary buttress fracture and should be classified as such because of the bones they affect, their symptoms and the surgical approaches used to treat them.
我们认为上颌骨内侧骨折是一种独特类型的鼻上颌骨支柱骨折，涉及梨状孔外侧缘、上颌额突和眶下缘内侧。本文旨在将上颌骨内侧骨折定义为一种独特类型的面骨骨折。
2010 年 5 月至 2013 年 6 月，我院收治 8 例上颌骨内侧骨折患者。每位患者均术前采用三维和多维 CT 扫描进行评估，并接受手术治疗。
8 例患者中男 7 例，女 1 例（平均年龄：17.5 岁）。常见的损伤机制是人际冲击，其次是小物体冲击。所有患者均有鼻出血和上颌神经及其分支感觉减退，部分患者还存在鼻畸形和/或复视。所有患者均采用口内入路，部分患者联合经眉弓下入路。上颌骨内侧骨折涉及上颌骨、泪骨、筛骨和/或鼻骨。上颌骨内侧骨折与鼻筛眶骨折的主要区别在于所累及的骨骼。
上颌骨内侧骨折是一种独特类型的鼻上颌骨支柱骨折，应将其归类为这种类型，因为其受累骨骼、症状和治疗所用的手术入路均有所不同。
