Snoring usually occurs because of various reasons in combination such as obesity, deviated nasal septum and pharyngeal muscular weakness. If your sleep study is suggestive of obstructive sleep apnea then just undergoing nose surgery may not help. You may need to reduce weight and try using CPAP. Surgery is the last option for obstructive sleep apnea. If it's just snoring then CPAP is not usually beneficial
