摘要

本院曾對45位因鼻竇鼻腔息肉病之患者施以電腦斷層掃描，檢查結果：所有病患息肉出現之部位除了鼻腔外，其在上頜竇，前篩竇及額竇之比率為80%，73%和58%；後篩竇及蝶竇則各為33%及24%。相關之放射線學所見包括篩竇漏斗擴大（佔67%），篩竇小梁骨破損（佔40%），鼻骨破損（佔35%）及篩竇側壁膨大（佔22%）。鼻竇電腦斷層檢查提供正確及寶貴之訊息使功能性內視鏡鼻竇手術更為功。

Forty-five patients with sinonasal polyposis were assessed with sinus computed tomographic examination. All of them showed bilateral polypoid masses in the nasal cavity with varying degree of obstruction. The inflammatory extension into the maxillary, anterior ethmoid and frontal: sinuses was noted to be 80%, 73% and 58%, respectively with concomitant involvement of the osteomeatal unit (OMU). The posterior ethmoid and sphenoid sinuses which drained into the sphenoethmoidal recess (SER) was found to be 33% and 24%, respectively. Associated findings suggestive of polypoid expansion were infundibular enlargement (67%), ethmoid trabecular erosion (40%), ethmoid lateral wall bulging (35%) and nasal bone erosion (22%). Providing excellent images that delineate the obstructive lesion in the drainage pathway, sinus CT scan aids in functional endoscopic sinus surgery (FESS).
