Outcome Measures

Primary Outcomes (2)

  • Change from baseline in nasal resistance and nasal flow after red light Change from baseline in nasal resistance and nasal flow after red light rhinophototherapy

    To compare the change from baseline in nasal resistance and nasal flow 30 minutes after red light rhinophototherapy by using active anterior rhinomanometry

    before and 30 minutes after red light rhinophototherapy

  • Change from baseline in the first and second minimal cross sectional area, and the volumes between the tip and 3.0 cm from the tip of the nosepiece and between 2.0 and 5.0 cm from the tip of the nosepiece after red light rhinophototherapy

    To compare the change from baseline in the first minimal cross sectional area of the nasal cavity, the second minimal cross sectional area of the nasal cavity, the nasal volume between the tip of the nosepiece and 3.0 cm into the nasal cavity, and the nasal volume of the nasal cavity between 2.0 and 5.0 cm from the tip of the nosepiece 30 minutes after red light rhinophototherapy by using acoustic rhinometry

    before and 30 minutes after red light rhinophototherapy

Secondary Outcomes (1)

  • rhinitis symptoms

    before red light rhinophototherapy, and 30 minutes and 2 days after red light rhinophototherapy

Study Arms (2)

intervention

EXPERIMENTAL

Transverse Many Channels Laser Instrument

Device: Transverse Many Channels Laser Instrument

control

NO INTERVENTION

Interventions

The device consists of a control box and 4 sets of two light-emitting nasal probes. Prior to treatment, each patient put on a pair of black tinted glasses, and had the nasal probes gently placed into both nostrils. A turn-on switch on the control box activated the probe and the timer was set at 15 minutes during which time 36 J of light energy was delivered to each nostril.
