Many people have difficulty breathing through their nose. This condition is not only uncomfortable, but may interfere with comfortable sleep or contribute to a more dangerous condition called Obstructive Sleep Apnea (OSA). Nasal obstruction may also interfere with patients ability to use their CPAP if they have already been diagnosed with OSA. Treatment is available if you have difficulty breathing through your nose. Options include medical treatment, septoplasty with turbinate reduction, and more comprehensive surgery of the nose (functional rhinoplasty).
