口腔颌面部解剖复杂,采用一般X线平片影像相互重叠,尤其对上颌骨深部,翼腭凹,咽旁,颈深部等软组织肿瘤为X线平片所不能达到,而CT扫描对之有独特的诊断价值。自1989年2月起,我们对3例咽旁、上颌骨深部肿瘤患者采用CT扫描诊断,报告如下。一、临床资料例1男,68岁。因左侧颌面部肿胀伴牙痛3月余,当地医院以“左上颌囊肿”手术,术后诊断为“左上颌窦癌”转入我院。CT报告:左鼻腔、师窦、蝶窦、眼眶有明显破坏,上颌窦肿块5cm×7cm,上颌窦后壁破坏,上达颅底,向后侵犯鼻咽腔,向内
Oral and maxillofacial anatomy is complex and overlaps with normal X-ray images. Especially for deep maxilla, pterygoid sulcus, parapharyngeal, deep neck, and other soft tissue tumors can not be achieved by X-ray film, and CT scans have Unique diagnostic value. Since February 1989, we have performed CT scans on 3 patients with parapharyngeal and maxillary deep tumors. The report is as follows. First, clinical data Example 1 Male, 68 years old. Due to left maxillofacial swelling with toothache for more than 3 months, the local hospital had a “left maxillary cyst” operation and a postoperative diagnosis of “left maxillary sinus cancer” was transferred to our hospital. CT report: left nasal cavity, sinus, sphenoid sinus, eyelid destruction, maxillary sinus mass 5cm × 7cm, maxillary sinus posterior wall destruction, up to the skull base, backward violation of the nasopharyngeal cavity, inward
