Blowing off the ear

Blowing off the ear - introduction of pressurized air through the auditory (Evstafieva) pipe in the tympanic cavity. Used in the treatment of acute and chronic inflammation of the middle ear, diseases of the auditory tube, after the operation of tympanoplasty and to determine the permeability of the auditory tube, often in combination with ear manometry.
Experience Valsalva (samoopredelenie). The patient does reinforced exhale with a closed mouth, pushing his fingers wings of the nose to the wall.

Blowing off the ear by Politzer

Blowing off by Politzer: olive from the container tightly injected into one nostril, clutching fingers of the opposite (see figure). Offer to speak to the patient words in syllables (for example, the PA-ro-stroke, sho-to-lad). At the moment of pronouncing the syllable, which is the stress, squeeze pear cylinder. Penetration of air in the tympanic cavity control using Otoscope - rubber tube, the ends of which there are olive trees. One of these olive injected into the ear of a patient, the other - in the ear doctor. With the passage of air in the tympanic cavity investigating the doctor hears a rustling sound or light crackling.
Catheterization performed by a physician with a special ear catheter.

Blowing off the ear is blowing air into the drum of the ear cavity through a pipe for diagnostic and therapeutic purposes.
Blowing off the ear produced by the following methods: (1) normal swallowing; 2) experience Toynbee (see Toynbee experience), 3) experience Valsalva (see Valsalva experience.)-, 4) the way Politzer, performed with a rubber cylinder capacity of 200-250 cm3 with levobrezni tip or United with the help of a rubber tube with olives. In both cases, the olive tree is put into one nostril (Fig. 1), which compresses over olive, wing-second nostrils densely press to the nasal septum. Patient offer on command to swallow the water and at the same time, squeezing a balloon is blown into the nose the air. At the time swallowing the soft palate is pressed against the back of the throat; nasopharynx hermetically closed, and blown pressurized air penetrates from the nose into the throat and through the ear tubes in both tympanic cavity.
Instead of swallowing water patient can speak the word that contains sanaatana sounds, which also calls the closure of the nasopharynx. A positive result
blowing ear confirmed patients (perception of light cod with further improvement of hearing), doctor: if you connect a rubber tube with olive trees at the ends of the patient ear and ear doctor, last listens blowing noise; when otoscopy normalization of position of the eardrum.
If necessary make blowing off only one ear use the method catheterization. After pre-anesthesia of nasal mucous membrane (lubrication 2% solution dikaina) catheter appropriate diameter with bent distal end and socket at the proximal end is carried through the lower nasal go to the back of the throat, turn catheter around its axis outwards at 90 degrees; then turned end of the catheter enters the pharyngeal hole ear tubes. The tip of the tank Politzer put to the mouth of the catheter and blown into the air in the pipe (Fig. 2). Catheterization must be made very carefully to avoid injury to the mucous membrane of the nose, pharynx, rupture of the eardrum.
