Evaluation of Blowing Exercises Utilizing a Breathing Exercise Device in Otitis Media With Effusion

Otitis media with effusion (OME) is a common condition in which fluid collects behind the eardrum without signs of infection. It can cause hearing problems and discomfort. Many children get better with medication, but in some cases, the condition becomes long-term and may require surgery. OME is caused by dysfunction of the Eustachian tube, which helps balance the air pressure between the middle ear and the back of the nose (nasopharynx). Restoring proper airflow to the middle ear is important. In addition to medication, physicians often recommend pressure-based exercises such as balloon-blowing, swallowing exercises, the Valsalva maneuver, or chewing gum. These exercises help open the Eustachian tube by creating positive pressure in the nasopharynx, which can improve ear ventilation and reduce symptoms by relieving negative pressure in the middle ear. This study will test the effect of a breathing exercise device called AirOFit PRO™ (AirOFit, Copenhagen, Denmark) in children with OME. Currently, there are no studies in the medical literature showing whether AirOFit PRO™ is effective in treating OME. If this study finds that using the AirOFit PRO™ helps children recover more quickly, it could be an important step in preventing chronic OME and reducing the need for surgery.

Intranasal Corticosteroid Spray for Preventing Otitis Media With Effusion After Radiotherapy in Nasopharyngeal Carcinoma

This study focuses on a common side effect experienced by many patients after radiation therapy for nasopharyngeal cancer, which is a type of head and neck cancer. This side effect is called secretory otitis media (fluid buildup in the middle ear). It can cause a feeling of fullness in the ear and hearing loss. While procedures like ear tube placement can help, they can also lead to other problems like ear infections and drainage. Radiation treatment is thought to cause inflammation that disrupts the normal function of the tube connecting the ear to the throat (Eustachian tube), leading to this fluid buildup. A nasal spray containing a steroid medicine (triamcinolone acetonide) is already known to be safe and effective at reducing inflammation in the ear fluid of both children and adults. We believe that using this spray may also help prevent and improve this condition in nasopharyngeal cancer patients after radiation therapy. The main goal of this study is to explore whether this nasal spray can effectively prevent or reduce fluid buildup in the ear following radiation therapy. We hope this non-invasive treatment will provide a new option to improve the quality of life for these patients.
