Are there any procedure to widen the nostril so as to improve breathing. Due to deviated septum my one nostril is blocked.

Septoplasty, turbinate reduction, alar batten grafts, spreader grafts---these are several examples of procedures that can be done to either widen the nostrils internally, or support the nose so it doesn't collapse while breathing. However, they typically won't make the outside of your nostrils look any wider.An in-person exam by an experienced rhinoplasty surgeon is necessary to determine the correct procedure for you. I suggest you consult with surgeons in your area for treatment recommendations. Good luck!

This is a great question! There are many procedures that can be performed to help with your nasal breathing. A septoplasty will correct a deviated septum, whereas sometimes a patient requires a rhino-septoplasty to not only correct the septum, but correct the internal nasal valve and open up the nasal airways and provide improvement in nasal breathing. Placement of cartilage grafts may sometimes widen the bridge or dorsum of the nose, but would not change the actual size of the nostrils (at least not externally). It seems like you will need to be formally examined before knowing what your surgical options entail! Good Luck to you!
