1. A method of delivering a fluid having a viscosity of less than about 3000 centipoise (cP) to a targeted sub-region of a subject's nasal cavity, the method comprising:
(a) ejecting a discrete volume of the fluid as a continuous stream from a dispensing element of a device;
(b) moving the continuous stream through an airspace in the nasal cavity towards the targeted sub-region;
(c) contacting an anatomical feature of the subject's nasal cavity with the continuous stream and forcing the fluid to move around the anatomical feature and towards the targeted sub-region; and
(d) contacting the targeted sub-region of the subject's nasal cavity with the fluid, thereby delivering the fluid to the targeted sub-region of the subject's nasal cavity
wherein the contacting the targeted sub-region of the subject's nasal cavity comprises depositing the fluid onto the targeted sub-region in a bolus deposition pattern, immediately following the contacting of step (d);
wherein the bolus deposition pattern comprises deposition of the continuous stream onto the targeted sub-region without substantial formation of droplets, immediately following the contacting of step (d).
