Abstract:
Objective:To investigate the changes of upper airway and adenoids in children with hypertrophic adenoid skeletal classⅠ and class Ⅲ anterior crossbite after orthodontic treatment.Methods:From January 2021 to January 2022,155 children with skeletal class Ⅲ anterior crossbite who were treated with anterior traction in Stomatological Hospital,Shanxi Medical University were selected.They were divided into class Ⅲ normal group(72 cases)and class Ⅲ hypertrophic group(83 cases)according to whether the adenoids were hypertrophic.A total of 122 children with class Ⅰ anterior counterocclusion were treated with"2×4"treatment,which were di-vided into Class Ⅰ normal group(60 cases)and class Ⅰ hypertrophy group(62 cases).The changes of upper airway and adenoid were compared between the two groups.Results:(1)After intervention,only the width of nasopharynx cavity increased(P＜0.05)in Class Ⅰ normal group and Class Ⅰ hypertrophic group,and there was no significant difference in other indicators(P＞0.05).(2)After intervention,the adenoid thickness and A/N ratio of children with skeletal class Ⅲ anterior crossbite decreased,and the width of na-sopharynx cavity,nasopharynx airway space,soft palate upper and rear airway space,uvula tip rear airway space,the minimum air-way space between soft palate and adenoid,and mandibular plane angle increased(P＜0.05).The A/N ratio of class Ⅲ hypertrophic group was lower than that of class Ⅲ normal group(P＜0.05).Conclusion:Orthodontic treatment can reduce the degree of adenoid hypertrophy and expand the airway in children with skeletal class Ⅲ anterior crossbite.Only the width of the nasopharynx cavity can be widened after the correction intervention for children with adenoid hypertrophy and skeletal class Ⅰ anterior crossbite.
