treats glue ear
Otovent treats glue ear (Otitis Media with Effusion, OME) by equalising negative pressure in the middle ear. When Otovent is used, positive pressure is generated in the nasopharynx, which equalises pressure in the middle ear at the Eustachian tube. Both the passive inflation phase and the active deflation phase enable the Eustachian tube to open. About half of all cases of glue ear will normally resolve in one to three months. However, because symptoms can last a long time, there may be a desire to speed up the process. Otovent can be used if the patient does not have an ear infection or an upper respiratory tract infection. Studies show that Otovent can equalise negative pressure in the middle ear, thereby improving hearing and relieving other symptoms of glue ear.
Four randomised controlled trials, all in children, have shown that using the device causes significant improvements, compared with standard care, in middle ear function; 1 of the trials also reported a significant reduction in the need for ventilation tube (grommet) insertion surgery.
Otovent® for prevention and relief
Otovent is the only proven clinically effective, non-surgical, drug-free treatment available for glue ear (OME). Regulating pressure in the middle ear is a known and important mechanism in the treatment of middle ear disorders in children and adults. Normally, pressure in the middle ear is equalised by swallowing or yawning. If the mechanisms to regulate negative pressure are not working properly, after a few weeks fluid will form, leading to hearing loss.
