No, the septum refers to the cartilage and bone that separates the nostrils. A deviated septum refers to when the septum is more to one side than the other. In slight cases, this may cause absolutely no issues or hindrances. However, some people experience breathing problems that can lead to or worsen certain medical conditions. It can also make exercise and strenuous activity difficult.
A surgical nose job is a common way to correct a deviated septum. Dermal fillers cannot achieve this or improve a deviated septum at all. Therefore, if this is one of the primary goals of nose enhancement, patients will likely be better candidates for surgical rhinoplasty.
