What Causes Blocked Ears Besides Sinus Problems?

Besides sinus problems, altitude changes and too much ear wax can cause ear blockage, states About.com. A foreign object in the ear can lead to ear blockage as well.

High altitudes can cause differences in pressure between the middle ear and the outer ear, notes About.com. Swallowing and yawning regularly can help open the auditory tubes and allow air into the ear. If left untreated, ear blockage that occurs due to changes in altitude may lead to barotrauma. A person who experiences problems with hearing or fluid drainage should consult with a doctor to avoid further problems.

Breathing in then breathing out gently with the mouth and nose shut may aid in balancing pressure on the two sides of the eardrum, thus unclogging the ear, explains MedlinePlus. People who experience plugged ears while flying should take decongestants an hour before taking flight.

Ear drops can help dissolve excess ear wax, explains About.com. Soaking the ears with water and gouging ear wax with a special tool may be helpful as well. However, the patient should seek a medical expert's advice prior to undertaking any of the procedures. Symptoms of ear blockage resulting from too much wax include dizziness, ringing in the ear, earache and cough, according to Mayo Clinic.
