[摘要] 目的 研究低剂量CT三维重建技术对儿童腺样体肥大所致上气道顺应性改变的客观评估价值。 方法 随机选取2014年9月—2015年6月该院收治的30例腺样体肥大患儿为观察组,以同期于该院进行健康体检的30例腺样体正常儿童为对照组。观察组患儿行CT低剂量扫描与症状计分表调查,并与对照组儿童的CT低剂量扫描后三维测量指标进行比较。 结果 观察组单位鼻咽腔的容积(rNPV)与鼻咽气道最狭窄处面积(rNPA)比值均低于对照组,差异具有统计学意义(P<0.05),且rNPA与症状严重程度呈负相关;rNPV与症状严重程度两者之间不存在相关关系。 结论 使用低剂量CT三维重建技术可对腺样体肥大所导致的儿童上气道顺应性改变进行客观评估,值得临床推广。

[Abstract] Objective The low dose CT 3 d reconstruction technology of adenoid hypertrophy in children caused by changes in the airway compliance objective assessment of the value. Methods Selection in our hospital treatment of 30 cases of children with adenoid hypertrophy were as the observation group, with the same period in our hospital for physical examination of 30 cases of adenoid body normal children as control group. Observation group role of low dose CT scanning and symptoms score table, and children with the control of low dose CT scanning after comparing three dimensional measurements. Results Observation group unit nasopharyngeal cavity volume (rNPV) and nose and breathe the most narrow area ratio (rNPA) are lower than the control group, difference has statistical significance (P < 0.05), and rNPA and negatively correlated with symptom severity; RNPV between symptom severity and there is no relationship. Conclusion Clinical treatment of adenoid hypertrophy in children can use the low dose CT 3 d reconstruction technology, to adenoid hypertrophy in children changes in airway compliance objective assessment, is worth promoting in clinic.

病理性腺样体肥大属于上呼吸道疾病,好发于儿童,严重肥大患者需进行手术切除治疗。目前,临床主要采用鼻咽部X线检查来测量腺样体的大小,评价腺样体与周围气道的关系,对低剂量CT三维重建评估儿童腺样体肥大导致上气道顺应性改变的报道较少[1]。该研究以2014年9月—2015年6月该院收治的30例腺样体肥大患儿为研究对象,对其实施低剂量CT三维重建检查,并与正常儿童做比较,以探讨低剂量CT三维重建技术对儿童腺样体肥大所致上气道顺应性改变的客观评估价值,现报道如下。

1 资料与方法

1.1 一般资料

随机选取2014年9月—2015年6月在该院确诊为腺样体肥大的患儿30例(观察组),男24例,女6例;年龄3~12岁,平均(5.8+2.6)岁。以同期于该院体检的30例腺样体无肥大症状且上气道顺应正常的儿童为对照组,其中男性21例,女性9例,年龄3~12岁,平均(6.8±3.4)岁。两组儿童性别、年龄等一般资料比较,差异无统计学意义(P>0.05),具有可比性。
