鼻窦肿瘤与眼眶的关系极为密切,眼眶受侵的程度和方式取决于肿瘤发生的部位。眼眶症状在上颌窦的肿瘤较筛颌角和筛窦的肿瘤出现为晚。鼻窦肿瘤最终都侵犯眼眶。眼眶症状又因肿瘤侵入的部位不同而各异。球后、上颌窦后部及筛窦的肿瘤常伴有眼球突出和睑裂增宽。生长缓慢的肿瘤眼球突出明显而无复视,复视表示肿瘤生长快而多为恶性。肿瘤虽然未直接侵入眼眶,但上颌窦肿瘤穿破后壁至翼腭窝,可致球后静脉瘀血而引起眼球突出。肿瘤侵及下颌关节时出现牙关紧闭,在早期张口时见下颌歪向一侧,如肿瘤侵及眶周则有明显的眼部前外角或内角肿胀的表 The relationship between sinus tumor and eyelid is extremely close, and the degree and manner of eyelid invasion depends on the site of tumor. Orbital symptoms appear later in the maxillary sinus than in the ethmoid and ethmoid antrum. Sinus tumors eventually violate the eyelids. The symptoms of eyelids vary depending on the site of tumor invasion. Posterior bulbar, posterior maxillary sinus, and ethmoid sinus tumors are often accompanied by exophthalmos and widening of the cleft palate. Slowly growing tumors have prominent eyes without diplopia. Diplopia indicates that tumors grow faster and are mostly malignant. Although the tumor has not directly invaded the eyelid, but the maxillary sinus tumor penetrates the posterior wall to the pterygopalatine fossa, which can cause the retrobulbar vein to bleed and cause eyeball protrusion. When the tumor invades the mandibular joint, the jaws are tightly closed, and when the mouth is opened early, the mandibular jaw is seen to one side. If the tumor invades the peri-orbital periphery, there is a marked swelling of the front outer corner or inner corner of the eye.
