The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients.
This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV), peak expiratory flow rate (PEFR), and ratio of FEV to FVC (FEV/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern.
Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17-63 years). The mean FVC, FEV, FEV/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns.

本研究旨在评估下颌骨骨折患者的肺功能，并确定这些患者的肺功能模式。
这是一项横断面研究，对2015年12月至2017年6月在我们医疗机构接受治疗的尼日利亚非吸烟孤立性下颌骨骨折患者的肺功能进行研究。在治疗前，使用便携式肺活量计测量所有参与者的用力肺活量（FVC）、一秒用力呼气容积（FEV）、呼气峰值流速（PEFR）以及FEV与FVC的比值（FEV/FVC）。将肺指标与尼日利亚人的预测参考值进行比较，以确定呼吸模式。
本研究纳入了40名参与者，其中6名女性（15.0%）和34名男性（85.0%），男女比例为1:5.7。患者的平均年龄为34.5±13.1岁（范围为17 - 63岁）。平均FVC、FEV、FEV/FVC和PEFR分别为3.8±1.2L、3.0±1.0L、74.3%±13.8%和5.2±2.2L/s。将数据与预测值进行比较后发现，17名受试者（42.5%）的肺功能模式正常，而23名受试者（57.5%）具有提示阻塞性和限制性肺功能模式的特征。
