How Can I Unblock the Sinuses and the Eustachian Tubes?

Decongestant pills or nasal sprays can help alleviate pressure in the eustachian tube and are also helpful in treating blocked sinuses. Simple acts, such as yawning, chewing gum or swallowing, can also help to unblock the eustachian tubes, according to MedicineNet.

The act of swallowing triggers muscles in the back of the throat to open the eustachian tube. Any activity that promotes swallowing, such as chewing gum, eating or drinking, will help, according to MedicineNet. If the ears still feel blocked despite attempting swallowing activities, the eustachian tubes can be forcibly opened by the act of blowing while keeping the nose pinched and mouth closed, suggests WebMD. In severe cases, pressure equalization tubes can be surgically inserted into the eardrum to regulate middle ear pressure.

Nasal decongestants and irrigation can help unblock nasal passages by loosening mucus, according to Harvard Women's Health Watch. Medications, such as guaifenesin and fluticasone, work to thin mucus and relieve inflammation in the sinus cavity. Inhaling steam or flushing the nasal cavity with water is a simple way to keep nasal passages clear. A nasal saline spray can be used throughout the day to keep nasal passages moist. It is also important to drink plenty of water to keep mucus thin and loose.
