To investigate the effect of adenoid hypertrophy on malocclusion and maxillofacial development in children.
Total of 102 children with malocclusion or maxillofacial dysplasia admitted to our hospital from March 2017 to June 2020 were selected as the research subjects. All children were divided into a control group (50 cases with adenoid hypertrophy) and an observation group (52 cases without adenoid hypertrophy) according to the presence or absence of adenoid hypertrophy. The incidence of malocclusion was compared between the two groups, and lateral cranial radiographs were taken in both groups to measure and compare the malocclusion angle, jaw angle, and jaw length indexes between the two groups.
The incidence of malocclusion in the observation group (71.15%) was higher than that in the control group (42.00%), and the difference was statistically significant ( < 0.05). The angle between the long axis of the upper central incisor and the nasal root point and the upper alveolar base point (U1-NA), the angle between the long axis of the lower central incisor and the nasal root point and the lower alveolar base point (L1-NB), the angle between mandibular plane and anterior cranial base plane (MP-SN), the angle between the long axis of upper central incisor and anterior cranial base plane (U1-SN), the angle between the long axis of lower central incisor and mandibular plane (L1-MP), the angle of axis, the overall height (N-Me), lower height (ANS-Me), overall height/back height (N-Me/S-Go), and lower height/overall height (ANS-Me/N-Me) values in the observation group were higher than those in the control group, while the mandibular length (Go-Gn) values in the observation group were lower than those in the control group ( < 0.05).
Adenoid hypertrophy can increase the incidence of malocclusion in children and can also increase the steepness and overall height and lower height of the mandible, resulting in the lengthening of the facial shape and the development of the maxillofacial deformity.
探讨腺样体肥大对儿童错牙合畸形及颌面发育的影响。
选取2017年3月至2020年6月我院收治的102例错牙合畸形或颌面发育异常患儿作为研究对象。根据是否存在腺样体肥大，将所有患儿分为对照组（腺样体肥大50例）和观察组（无腺样体肥大52例）。比较两组错牙合畸形的发生率，并对两组患儿进行头颅侧位X线片拍摄，测量并比较两组患儿的错牙合角、颌角及颌骨长度指标。
观察组错牙合畸形发生率（71.15%）高于对照组（42.00%），差异有统计学意义（<0.05）。观察组上中切牙长轴与鼻根点及上牙槽座点连线的夹角（U1-NA）、下中切牙长轴与鼻根点及下牙槽座点连线的夹角（L1-NB）、下颌平面与前颅底平面的夹角（MP-SN）、上中切牙长轴与前颅底平面的夹角（U1-SN）、下中切牙长轴与下颌平面的夹角（L1-MP）、轴角、全面高（N-Me）、下前牙高（ANS-Me）、全面高/后牙高（N-Me/S-Go）及下前牙高/全面高（ANS-Me/N-Me）值均高于对照组，而观察组下颌骨长度（Go-Gn）值低于对照组（<0.05）。
腺样体肥大可增加儿童错牙合畸形的发生率，还可增加下颌骨的陡度、全面高及下前牙高，导致面形变长及颌面畸形的发生。
