Nasal breathing protects the upper airway and is responsible for adequate craniofacial development. It is believed that long-standing obstruction causes mouth breathing, which has a negative impact on the craniofacial complex.
The study aimed to verify the effects of mouth breathing on the dentofacial structure by employing cephalometric analysis.
The present study was conducted on 68 patients (34 mouth-breathing group or study group and 34 nasal-breathing group or control group) aged 6-14 years. Study subjects were screened based on the inclusion and exclusion criteria. Clinical assessment of nasal function was done to select the mouth breathing patients and referred for ear, nose, and throat (ENT) clearance. Lateral cephalograms were taken for the study subjects, including both nasal and mouth breathers, over which selected landmarks were marked to evaluate linear, skeletal, and dental angular variables for comparison with cephalometric variables of a normal child.
The mean values of facial height (N-Me, ANS-Me) and mandibular plane angle (SN-GoGn) were significantly higher for mouth breathers. The gonial angle (Ar-GoMe) for ages 6-14 years was significantly lower in the nasal breathing group.
The study led to the conclusion that all subjects with a history of mouth breathing showed an increase in facial height, gonial angle, and mandibular plane angle.
Evaluating dentoskeletal changes in a patient with a mouth-breathing habit helps discern the importance of early identification and interception at an early age, thereby ensuring a functional environment adequate for physiological growth and dentofacial esthetics.

经鼻呼吸可保护上呼吸道,并对头面部的充分发育负责。人们认为长期的气道阻塞会导致口呼吸,这会对面颅复合体产生负面影响。
本研究旨在通过头影测量分析来验证口呼吸对牙颌面结构的影响。
本研究对68例年龄在6至14岁的患者进行(34例口呼吸组即研究组和34例经鼻呼吸组即对照组)。研究对象根据纳入和排除标准进行筛选。对鼻腔功能进行临床评估以选择口呼吸患者,并转诊至耳鼻喉科进行检查。为研究对象拍摄头颅侧位片,包括经鼻呼吸者和口呼吸者,在其上标记选定的标志点,以评估线性、骨骼和牙齿角度变量,以便与正常儿童的头影测量变量进行比较。
口呼吸者的面部高度(N-Me、ANS-Me)平均值和下颌平面角(SN-GoGn)显著更高。6至14岁年龄段的下颌角(Ar-GoMe)在经鼻呼吸组中显著更低。
该研究得出结论,所有有口呼吸史的受试者面部高度、下颌角和下颌平面角均增加。
评估有口呼吸习惯患者的牙骨骼变化有助于认识到早期识别和干预的重要性,从而确保有利于生理生长和牙颌面美观的功能环境。
