Nasal septum deviation is a common physical disorder of the nose, involving a displacement of the nasal septum.In most cases a deviated septum can be corrected with a minor surgical procedure known as a septoplasty in which the surgeon enters through the nostrils and cuts away the obtruding matter. The surgery is performed quickly (it takes around 1 hour) but the patient may take one to three weeks to fully recover.
