This study evaluated maxillary sinus volume changes in military jet aircraft pilot candidates before and after the training program, in comparison with a control group, considering the effects of pressurization, altitude, and total flight hours, through multislice computed tomography.
Fifteen fighter pilots were evaluated before initiating the training program and after the final approval. The control group consisted of 41 young adults who had not flown during their military career. The volumes of each maxillary sinus were measured individually before and at the end of the training program.
When comparing the initial and final volumes in the pilots, a statistically significant increase was observed both in the left and right maxillary sinuses. When evaluating the average total volume of the maxillary sinuses (i.e., the average volume of the right and left maxillary sinuses together), a significant increase in the volume of the maxillary sinuses was observed in the pilot group when compared to the control group.
The maxillary sinus volumes in aircraft pilot candidates increased after the 8-month training program. This may be explained by changes in the gravitational force, the expansion of gas, and positive pressure from oxygen masks. This unprecedented investigation among pilots might lead to other investigations considering paranasal sinus alterations in this singular population.
本研究通过多层计算机断层扫描，评估军事喷气式飞机飞行员候选人在训练计划前后上颌窦容积的变化，并与对照组进行比较，同时考虑增压、海拔高度和总飞行小时数的影响。
15名战斗机飞行员在开始训练计划前和最终批准后接受评估。对照组由41名在军事生涯中未飞行过的年轻人组成。在训练计划开始前和结束时分别测量每个上颌窦的容积。
比较飞行员的初始和最终容积时，发现左右上颌窦均有统计学上的显著增加。在评估上颌窦的平均总体积（即左右上颌窦的平均容积之和）时，与对照组相比，飞行员组的上颌窦容积有显著增加。
经过8个月的训练计划后，飞机飞行员候选人的上颌窦容积增加。这可能是由重力变化、气体膨胀和氧气面罩产生的正压所解释。这项针对飞行员的前所未有的调查可能会引发其他关于这一特殊人群鼻窦改变的调查。
