We listen and talk to the patient about his/her concerns. The cause of obstruction can be due to swelling of nasal tissues, infection, or a mechanical obstruction due to displaced bone or cartilage. Often, nasal obstruction can be relieved by medicine or allergy treatment. If the problem is mechanical obstruction, however, surgery often offers the fastest and surest road to recovery. Surgery can involve straightening out the nasal septum and enlarging the nasal airway. Nasal surgery is most often a day surgery and no hospitalization is required.
