【摘要】：目的 探討嬰幼兒小下頜畸形伴阻塞性睡眠呼吸暫停綜合征(0SAS)的CT征象。方法 對42例小下頜伴OSAS的患兒(小下頜組)進行CT檢查。同期選取26例下頜骨發(fā)育正常但因其他疾病接受頸、頜面部CT檢查的患兒作為對照組。測量下頜骨左右徑(A_線)、前后徑(B_線)和下頜骨體夾角(α°),計算A線/B線比值;分別測量上氣道腭咽區(qū)、舌咽區(qū)及喉咽區(qū)最狹窄處橫截面積(CSA,CSA_腭、CSA_舌、CSA_喉)、矢狀徑(AP,AP_腭、AP_舌、AP_喉)和橫徑(LR,LR_腭、LR_舌、LR_喉)。并對各測量值進行比較分析。結(jié)果 與對照組比較,小下頜組下頜骨B線縮短,A線/B線比值、α°增大,CSA舌、AP舌減小,LR舌增大,差異均有統(tǒng)計學意義(P均0.05)。小下頜組的CSA_舌與A線、B線均呈正相關(guān)(r=0.30、0.41,P均0.05),與A線/B線比值、α°均呈負相關(guān)(r=-0.36、-0.41,P均0.05);CSA_喉與A線呈正相關(guān)(r=0.34,P0.05)。結(jié)論 小下頜畸形伴OSAS患兒同時存在下頜骨短小后縮和上氣道的狹窄,頜面部CT表現(xiàn)具有一定特征性,對早期診斷具有提示作用。
[Abstract]:Objective to investigate the CT features of infant mandibular malformation with obstructive sleep apnea syndrome (0SAS). Methods 42 cases of small mandible with OSAS (small mandible group) were examined with CT. At the same time, 26 children with normal mandibular development but underwent CT examination of maxillofacial region due to other diseases were selected as control group. The right and left diameters of the mandible (A _ line), the anteroposterior diameter (B _ line) and the angle between the mandibular body (偽 擄) were measured, and the ratio of line A to line B was calculated, and the palatopharynx area of the upper airway was measured, respectively. The cross sectional area of the most narrow part of the glossopharyngeal area and the larynx area (CSA,CSA_ palatoglossus), the sagittal diameter (AP,AP_ palatine apoglossal larynx) and the transverse diameter (LRL _ LR _ LR _ larynx) were found in the glossopharyngeal area and the larynx of the larynx. The measured values are compared and analyzed. Results compared with the control group, the ratio of line B to line B of mandible was shortened, the ratio of line A to line B and the ratio of line A to line B, and the ratio of There was a positive correlation between CSA_ tongue and line A line B (P 0.05), and a negative correlation with line A / B line ratio and 偽 擄(r = 0.36 ~ 0. 36 ~ 0. 41% P = 0. 05). There was a positive correlation between CSA_ _ larynx and A line (r = 0. 34 P 0. 05). Conclusion short mandibular retraction and upper airway stenosis also exist in children with small mandibular malformation and OSAS. The CT findings of maxillofacial region are characteristic, which may be helpful for early diagnosis.
