To prevent barotitis during descent in aviation, the ears have to be cleared several times by performing the Valsalva's manoeuvre. The manoeuvre is difficult for children to perform, and they are therefore at high risk of developing barotitis. The treatment of barotitis is either inflation by a Politzer balloon or myringotomy. An alternative treatment is autoinflation using the Otovent. This prophylaxis/treatment can be performed by the child with assistance from its parents as soon as or preferably before the descent has started. The prevalence of barotitis amongst 45 children and 49 adults in transit was found to be highest in children, 28%, compared with adults, 10%. Only 6% of the children with negative middle ear pressure after flight managed a successful Valsalva manoeuvre, whereas 33% could normalise the middle ear pressure by inflating the Otovent. In conclusion we recommend autoinflation using the Otovent set by children and adults who have problems clearing their ears during flight.
为预防航空下降过程中的气压性中耳炎，必须通过进行瓦尔萨尔瓦动作多次清理耳朵。该动作对儿童来说很难完成，因此他们患气压性中耳炎的风险很高。气压性中耳炎的治疗方法是使用波利策尔球囊进行充气或鼓膜切开术。另一种治疗方法是使用Otovent进行自主充气。这种预防/治疗方法可以在下降开始时或最好在下降开始前，由儿童在父母的协助下进行。在45名儿童和49名过境成年人中，气压性中耳炎的患病率在儿童中最高，为28%，而成年人中为10%。飞行后中耳压力为阴性的儿童中，只有6%成功完成了瓦尔萨尔瓦动作，而33%的儿童可以通过给Otovent充气使中耳压力恢复正常。总之，我们建议有飞行时耳部清理问题的儿童和成年人使用Otovent进行自主充气。
