A method of vibration treatment in at least one nasal cavity of a human subject is provided. The method includes the steps of: inserting a first stimulation member in a first nasal cavity; inserting a second stimulation member in a second nasal cavity; securing the first and second stimulation members such that the stimulation members are in fixed positions within the nasal cavities prior to vibration stimulation; arranging each of the first and second stimulation members to abut against tissue within each of the first and second nasal cavities at a first and second pressure; and imparting vibrations to tissue in at least one of the first and second nasal cavities via at least one of the first and second stimulation members.
