The bone and cartilage that separates the inside of the nasal cavity is called the septum. Ideally, the nasal passages have equal space on the left and the right, and this bone is directly in the center. However, it is very common for the septum to deviate to one side. A deviated septum can cause nosebleeds, increased snoring, headache, post-nasal drip, sinus infections, and persistent stuffiness on one side of the nose. Septal deviation is also visible as a “crooked nose” in some cases. During septoplasty surgery, this bone is straightened, allowing for better airflow and nasal function. This surgery can be performed under twilight sedation or general anesthesia and can be combined with any cosmetic or functional procedure for the nose.
