The Influence Of Adenoid And Tonsil Hypertrophy On The Maxillofacial Development Of Crossbite Children

Objectives1.To find out the influence of adenoid hypertrophy,tonsil hypertrophy and adenotonsillar hypertrophy on profile of crossbite children with primary dentition.2.To find out the influence of adenoid hypertrophy,tonsil hypertrophy and adenotonsillar hypertrophy on profile of crossbite children with mixed dentition.3.To observe the profile changes between crossbite patients with primary dentition and mixed dentition,both of whom are suffering from adenoid hypertrophy,tonsil hypertrophy or adenotonsillar hypertrophy.4.To establish a set of examinations including clinical intraoral examination,mouth breathing self-check,cephalometric analysis,Polysomnography,ect.It can help with diagnosis and prognosis.MethodThere are 68 included cases and all cases went through clinical intraoral examination,mouth breathing self-check and cephalometric analysis.These cases were divided into primary dentition group and mixed dentition group according to their dental age and were divided into control group,adenoid hypertrophy group,tonsil hypertrophy group and adenotonsillar hypertrophy group according to obstructive position in the upper airway.Compare the differences of cephalomatric data between different groups using statistic analysis.Results1.As to crossbite patients with primary dentition,(1)adenotonsillar hypertrophy without mouth breathing tend to concave profile,and the severer the hypertrophy is,the severer the deformity becomes;(2)adenoid hypertrophy without mouth breathing doesn’t have much influence on profile;(3)patients with adenotonsillar hypertrophy tend to have severer concave profile compared to those with adenoid hypertrophy,and the severer the hypertrophy is,the more obvious the difference is.2.As to crossbite patients with mixed dentition,(1)adenotonsillar hypertrophy with mouth breathing tend to convex profile,and the severer the hypertrophy is,the severer the deformity becomes;(2)tonsil hypertrophy may tend to concave profile;(3)patients with adenotonsillar hypertrophy have severer convex profile compared to those with tonsil hypertrophy,and the severer the hypertrophy is,the more obvious the difference is.3.Adenoid and/or tonsil hypertrophy leads to two different kinds of prognosis,which is decided by the breathing compensation mode:children who are used to mandible protrusion result in concave profile,while children with mouth breathing result in convex profile.Mouth breathing lead to convex profile,but it won’t be an improvement of profile for crossbite children because mouth breathing may lead to mandible clockwise rotation.These patients should receive timely treatment and kick the mouth breathing habitConclusions1.The change of breathing mode is an important reason for skeletal deformity in children suffering adenoid and/or tonsil hypertrophy.There two kinds of breathing compensation mode:mouth breathing leading to convex profile and mandible protrusion leading to concave profile.The severer the hypertrophy is,the severer the deformity is.2.Adenoid and/or tonsil hypertrophy causes maxillofacial deformity at an early age,and the earlier it happens,the severer the deformity becomes.Patients should go through a set of examinations including clinical intraoral examination,mouth breathing self-check,cephalometric analysis,Polysomnography,ect.Then they should receive timely treatment and kick the harmful breathing habits as soon as possible.
