Mouth breathing is one of the most common oral and maxillofacial abnormalities in children. Children with mouth breathing are often accompanied by obstructive sleep apnea, which not only affects children's dentofacial development, leading to the occurrence of malocclusion, but also may lead to a series of serious systemic complications. The diagnosis and treatment of mouth breathing and its related malocclusions require multidisciplinary collaboration. This paper discusses the etiology and harm of mouth breathing, diagnosis of mouth breathing related problems, correlation between mouth breathing and malocclusion, treatment of mouth breathing related malocclusions.
口呼吸是儿童最常见的口颌面功能异常表现。儿童口呼吸常伴阻塞性睡眠呼吸暂停的发生，其不仅影响儿童颅颌面发育、导致错(牙合)畸形，还可能引起一系列严重的全身并发症。口呼吸及其相关错(牙合)畸形的诊断治疗需要多学科协作。本文从口呼吸的病因与危害、口呼吸相关问题的诊断、口呼吸与错(牙合)畸形的相关性、口呼吸相关错(牙合)畸形的治疗4个方面进行论述，以期为临床提供参考。.
