目的 探讨CT检查对鼻窦炎性疾患的诊断意义。方法 对经X线克瓦位平片诊断为鼻窦炎的患儿10 8例进行CT扫描。结果 急性鼻窦炎 38例占 35 2 % ,表现为上颌窦内高密度影 ,CT值 15～ 38Hu ,其中伴有筛窦炎症 31例 ,额窦炎症 9例 ,蝶窦炎症 13例 ,上颌窦窦壁骨质吸收 5例 ,腺样体肥大 2 8例 ;慢性鼻窦炎 5 6例占 5 1 9% ,表现为上颌窦内高密度影 ,CT值 30～ 6 5Hu ,其中伴息肉样鼻窦炎 16例 ,粘膜下囊肿 19例 ,鼻腔息肉6例 ,上颌窦窦壁骨质硬化增白 3例 ,腺样体肥大 41例 ;变态反应性鼻窦炎 11例占 10 2 % ,CT值 2 5～ 45Hu ,均表现为沿窦壁波浪状密度增高影 ;鼻窦正常发育变异患儿 3例占 2 8% ,CT值 - 170～ - 36 2Hu。结论 鼻窦炎性疾患治疗前做鼻窦CT检查能明确病变的性质 ,对临床治疗方法的选择以及判断预后有临床意义。
Objective To investigate the diagnostic value of CT examination for sinusitis. Methods CT scan was performed in 108 children diagnosed as sinusitis by plain radiograph. Results 38 cases of acute sinusitis accounted for 35 2%, showing the high density of the maxillary sinus, CT value of 15 ~ 38Hu, which associated with ethmoid sinus inflammation in 31 cases, frontal sinusitis in 9 cases, sphenoid sinusitis in 13 cases, maxillary sinus 5 cases of esophageal bone absorption, 28 cases of adenoid hypertrophy; chronic sinusitis 56 cases accounted for 51.9%, showing the high density of the maxillary sinus, CT value 30 ~ 6 5Hu, with polyps sinusitis 16 Cases, 19 cases of submucosal cysts, nasal polyps in 6 cases, 3 cases of maxillary sinus osseous sclerosis, 41 cases of adenoid hypertrophy; 11 cases of allergic rhinitis accounted for 102%, CT value 25 ~ 45Hu , All showed an increase of wave density along the sinus wall; 3 cases of normal sinusoidal variation in children accounted for 28%, CT value - 170 ~ - 36 2Hu. Conclusion Sinusitis Sinus disease before the treatment of sinus CT can clear the nature of the disease, the choice of clinical treatment and prognosis of clinical significance.
