1. A method of modifying a property of a nasal tissue of or near a nasal valve of a nose, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in a nasal airway, the method comprising:

contacting a treatment element of a cryotherapy treatment device with the nasal tissue inside the nasal airway;

removing energy from the nasal tissue using the treatment element of the cryotherapy treatment device to modify the property of the nasal tissue, wherein the nasal tissue at least partially maintains the modified property after the treatment element is removed and the nasal tissue heals; and

removing the treatment element from the nostril.

2. The method of claim 1 , wherein removing energy from the nasal tissue comprises delivering cryotherapy uniformly over an entire outer surface of the treatment element, thereby treating all nasal tissue in contact with the treatment element.

3. The method of claim 1 , wherein removing energy from the nasal tissue comprises engaging elements distributed across the treatment element to cool only targeted areas of the nasal tissue.

4. The method of claim 1 , wherein the property of the nasal tissue comprises the tightness of one or more sections of an epithelium of an inner surface of the nasal valve.

5. The method of claim 1 , wherein the property of the nasal tissue comprises the strength of cartilage in the area of the upper lateral cartilage.

6. The method of claim 1 , wherein removing energy from the nasal tissue creates localized tissue damage.
