FIELD: methods for administering drugs into patient's body, in particular into nasal accessory sinuses. SUBSTANCE: proposed method comprises administering drug into nose, while closing external auditory passages, thereby creating pressure difference between nasal cavity and nasal accessory sinuses. Inventive novelty of proposed method resides in fact that patient's eyelids are additionally pressed-on. Use of proposed method rules out possibility for leaks through nasolacrimal canals from pressurized nasal cavity, thereby preventing medicaments and pathologically infected contents of nasal cavity from penetrating into internal angles of patient's eye that os possible in case of using pressure for administering medicaments into nasal accessory sinuses. EFFECT: more effective and reliable delivery of medicaments; greater safety for patients.
