本文对鼻及鼻窦与眶部的解剖关系重点作了介绍,指出:(1)眶骨膜为致密的纤维组织,是防止病变扩至眶内的屏障。(2)眶上裂和眶下裂为病变侵入的通道。(3)眼部静脉无瓣膜,感染容易扩散。炎症:鼻窦的炎症是发生眼及眶部合并症的常见原因。筛窦炎时上颌骨额突部水肿;额窦炎时水肿限于眼睑的内、上部;上颌窦炎水肿见于下脸。额窦及筛窦炎常发生眶骨膜下脓肿,致眼球向外侧移位。眶内脓肿,眼球突出,视力受损和眼肌麻痹。鼻窦囊肿:因鼻额管较长,最易受阻,所以额窦囊肿二倍于筛窦。一旦发生鼻窦囊肿同样可出现眼部症状,晚期也可影响视力。鼻窦肿瘤:骨瘤多无症状,仅偶然发现。当
This article focuses on anatomy of the nasal and nasal sinus and orbital parts were introduced, pointed out: (1) orbital periosteum is a dense fibrous tissue, is to prevent lesions extended to the orbital barrier. (2) superior orbital fissure and infraorbital fissure pathways for invasion. (3) No ophthalmic vein valve, infection is easy to spread. Inflammation: Sinus inflammation is a common cause of eye and orbital complications. Ethmoid sinus edema frontal protrusion; Frontal sinusitis edema limited to the upper eyelid; upper edema seen in the next face. Frontal sinus and ethmoid sinus periorbital submucosal abscess often occurs, resulting in lateral displacement of the eye. Orbital abscess, prominent eyes, impaired vision and ophthalmoplegia. Sinus cysts: Due to the nasal tube longer, the most easily blocked, so frontal sinus cysts twice in the ethmoid sinus. Sinus cyst in the event of the same eye symptoms can occur, late may also affect vision. Sinus cancer: osteoma more asymptomatic, only by chance. when
