在过去文献上尚未见到单纯上颌骨额突和眶下缘内侧骨折的报导,此种骨折常与鼻骨骨折、鼻上颌骨折、blowout骨折(译者注:指眶下壁骨折)或颧骨骨折相混淆,鉴别各种骨折非常重要,因不同骨折有不同的处理方法,作者报告9例,并提出诊断要点和处理原则。全部患者为男性,骨折由外伤引起,物理体征有:眶周围皮下瘀斑、结合膜下出血、鼻阻塞、眶下缘可触及阶梯样高低不平并有压痛。9例患者中4例出现眶下神经感觉异常;1例患者向上看时限外肌运动受限。上颌骨内壁骨折在瓦氏位X线摄片上显示四个诊断征象:即上颌窦模糊或出现液平、眶下缘内侧呈阶梯样、碎骨片向下向内向梨状孔移位及鼻腔狭窄。 In the past literature there was no report of simple maxillary frontal and medial orbital margin fractures, which are often associated with nasal bone fractures, nasal maxilla fractures, blowout fractures, or zygomatic fractures To confuse and identify various fractures is very important because of different fractures have different treatment methods, the authors report 9 cases, and put forward the diagnosis points and principles. All patients were male and the fractures were caused by trauma. The physical signs were subcutaneous ecchymosis around the orbit, conjunctival hemorrhage and nasal obstruction, and the inferior orbital rim could touch the step-like unevenness with tenderness. Four of the nine patients had suborbital nerve sensory abnormalities; one patient was limited in time to look at the muscular movement outside. Maxillary internal wall fractures in the Valsalva X-ray showed four diagnostic signs: the maxillary sinus fuzzy or appear level, the medial orbital rim was stepped, broken bone downward and inward to the pear-shaped hole and nasal stenosis .
