what do you know about Otitis Media



Inflammation of the inner ear (OM) is most common in children, and much of interest to adults. Plaintiffs, protracted ear inflammation causes pain, restlessness and muffled hearing, which can hamper development and prejudice learning. Otitis is one of the main reasons for visiting the doctor or emergency room.
Block Eustachian tube (OT), which connects the middle ear cavity to the oral cavity can be a major cause of inflammation or a secondary factor - caused by inflammation and swelling of the mucous membrane of the ear and blocking the Eustachian canal.

The opening of the Eustachian tube is an important and essential step towards the healing of inflammation. Blocking the canal prevents drainage of the fluids secreted by the mucous membrane of the middle ear and prevents the air pressure equal on both sides of the eardrum. This increases the pressure inside the ear cavity and pushes the eardrum outwards, leading to pain, muffled hearing, and occasionally problems with balance. Furthermore, the increased pressure in the middle ear cavity prevents the absorption of drugs in the region via local osmosis (eardrops) or systemically (via the blood).

Prevailing health care - until now, treatment has involved the use of steroids and pseudo-epinephrine to reduce edema, with antibiotic cover for primary bacterial infection or secondary complication. If medical treatment and the inflammation does not recur, despite extended antibiotic treatment, the practice is to perforate the tympanic membrane and ensure that it stays open by inserting small tubes drain. This allows the contents of the middle ear cavity to drain out, equalizing pressure, improving hearing, stop the pain and the medication that allowed local and heal.

The device was invented recently called EarDoc (Figure 1). EarDoc is a small electric device with low-cost treatment and the opening of the Eustachian tube. It works by producing vibrations at a frequency sub-sonic. The instrument head is specially designed so that when positioned behind and resting on the ears, swelling in the head of the device against the frontal bone and mastoiditis noted section rests against the base of the ear.

The front of the head of the device causes the cartilage of the ear base to vibrate along the external auditory canal to the tympanic membrane. The vibrating membrane produces a small pressure waves affecting the air pressure and fluid middle ear cavity. The first pressure within the middle ear cavity is converted into cyclical waves, which act as shock waves exert pressure on the walls of reduced or blocked Eustachian tube. Furthermore, the vibration of the head of the device through the bone mastoiditis in the wall of the middle ear cavity produce vibrations in the inflammation of the mucous membrane of the middle ear canal and Eustachian tube, reducing edema. This combination greatly improves the possibility of opening the canal and allow the trapped air and fluids from the middle ear cavity to drain into the mouth.

Adjusting the frequency helps to improve the effectiveness of the device in several ways: the optimum operating frequency is different for each individual depending on the size of the middle ear cavity and the Eustachian tube, which naturally vary. Adjustment also improves the oscillation frequency of the mucous membrane. It is recommended that the patient should gradually adjust the frequency to cover the entire frequency range. EarDoc be used for 3-5 minutes approximately six times a day when the channel is blocked or reduced. This improves the probability of open channels and ensure that it remains open, and provides immediate pain relief, improved absorption of drugs, and healing of inflammation.

Air travel and diving - Block of the Eustachian tube is a trivial consequence of aviation and diving. Fluctuations of the differences in atmospheric pressure air on both sides of the tympanic membrane cause reduced pressure in the middle ear cavity, swelling of the mucous membrane of the cells of the inner ear, and the increase in secretion of fluid. This produces a vicious circle in which the pressure increased, the narrower becomes the Eustachian tube and less efficient drainage of fluid and can compensate for atmospheric pressure. The reduction of operating the tube causes insufficiency in the canal and lock. Inflammation of the pharynx and upper respiratory tract that extends to early swelling of the mucous membrane exacerbate the phenomenon and the risk of blockage. Using EarDoc flights during and after the immersion sessions can reduce pain and produce healing as described above.

Inflammation of the breast - like the middle ear cavity, when the sinus drain is blocked due to swelling or inflammation of the mucous membrane of the sinus cavity, can help EarDoc resting against the bone adjacent to the breast, to open l 'opening and closing to allow drainage and healing.
