There are a variety of conditions which may cause the sensation of a 'blocked nasal passage' including a deviated septum, enlarged turbinates, collapse of the external nasal valve, narrowing of the nasal internal valve, scar tissue from previous surgery, and functional disorders of the inner lining, mucosa, or nose. All of these may lead to turbulent airflow or airflow resistance, resulting in symptoms of nasal obstruction. Dr. Naderi, who is a true rhinoplasty surgeon with an otolaryngology (ENT) background, has the skills necessary to identify and correct these problems. In fact, many of the 'tough' cases in Washington DC Area, Chevy Chase, Virginia, and of local ENT surgeons are referred to Dr. Naderi because his ability and holistic approach allow him to address all issues which may be contributing to a problem.
