There is a substantial amount of evidence to support the theory that the spatial relationship of the mandible to the craniomaxillary complex is influenced, in part, by the function of the muscular elevators of the mandible. One factor acting on the elevators of the mandible is the rest position of the mandible, which may be influenced by the patient's mode of respiration. Obstruction of the nasal airway is followed by the lowering of the mandible to establish an oral airway. Allergic rhinitis is one cause of nasal airway obstruction. There are reports that avoidance of the ingestion of foreign airway. The orthodontist should recognize early signs of the development of the long face syndrome and make appropriate referrals to medical colleagues to promote nasopharyngeal health.
有大量证据支持这样一种理论，即下颌骨与颅上颌复合体的空间关系部分受到下颌骨肌肉提升肌功能的影响。作用于下颌骨提升肌的一个因素是下颌骨的休息位，它可能受患者呼吸方式的影响。鼻气道阻塞后，下颌骨会下降以建立口腔气道。变应性鼻炎是鼻气道阻塞的一个原因。有报告称避免摄入异物气道。正畸医生应认识到长面综合征发展的早期迹象，并适当地转诊给医学同事以促进鼻咽部健康。
