Regularly using a CPAP machine may have some effects on facial structure, however, there are few reported cases concerning such issues. Periorbital edema refers to swelling around the eyes and this can be caused by an incorrectly fitting mask that leaks air around your eyes resulting in possible puffiness, or an obstruction to your venous system or lymphatic draining system. The most common cause of this issue tends to be a mask that fits too tightly. Should any users experience issues of this kind, they should seek advice from their doctor who will be able to provide them with a more appropriately fitting mask or one of a different style that doesn’t obstruct or put pressure onto these areas of their face.
It is also advised to monitor children who require the use of a CPAP mask to prevent any issues with facial growth problems. This will typically be an effect of the pressure of the mask against their nose. Again, finding the best style of mask for their requirements will help to ease such issues and also using nasal pillows which will help to relieve any pressure.
As mentioned, there aren’t a lot of reported cases regarding this issue and you will typically find that most users try out a range of different masks before settling on the style that they consider the most comfortable.
