1. A method comprising:
(a) inserting a first dilation catheter into a first nostril of a patient;
(b) inserting a second dilation catheter into a second nostril of the patient;
(c) positioning a first dilator of the first dilation catheter between a nasal septum of the patient and a turbinate of the patient;
(d) positioning a second dilator of the second dilation catheter adjacent to the nasal septum of the patient;
(e) expanding the first dilator, thereby remodeling two or more of the nasal septum, the turbinate, or mucosal tissue of the patient;
(f) expanding the second dilator, wherein the first and second dilators are expanded simultaneously;
(g) removing the first dilation catheter from the first nostril of the patient; and
(h) removing the second dilator from the second nostril of the patient.
 
14. A method comprising:
(a) positioning a first dilator between a first side of a nasal septum and a first turbinate in a nasal cavity of a patient;
(b) positioning a second dilator between a second side of the nasal septum and a second turbinate;
(c) expanding the positioned first dilator; and
(d) expanding the positioned second dilator,
wherein expansion of the positioned first dilator urges the nasal septum toward the second dilator,
wherein expansion of the positioned second dilator restricts movement of the urged nasal septum,
wherein expanding the positioned second dilator occurs simultaneously with expanding the positioned first dilator, wherein simultaneously expanding the first and second dilators reduces a likelihood of fracturing bone within the first and second turbinates, while still crushing mucosa of the first and second turbinates.
 
17. A method comprising:
(a) inserting a first dilation catheter into a first nostril of a patient;
(b) positioning a first dilator of the first dilation catheter between a first side of a deviated nasal septum of the patient and a turbinate of the patient;
(c) inserting a second dilation catheter into a second nostril of the patient;
(d) positioning a second dilator of the second dilation catheter adjacent to a second side of the deviated nasal septum of the patient;
(e) expanding the positioned first dilator to medialize the deviated nasal septum, thereby remodeling the deviated nasal septum to achieve a substantially straight configuration of the nasal septum; and
(f) expanding the positioned second dilator to restrict movement of the nasal septum beyond the substantially straight configuration, wherein expanding the positioned second dilator occurs simultaneously with expanding the positioned first dilator.
