These infections are “caused by bacteria and often begin after a child has a sore throat, cold, or other upper respiratory infection…Because of the infection, fluid builds up behind the eardrum” (Ear Infections in Children, 2014). “Fluid may build up in the middle ear for several reasons.… Sometimes the fluid…

of Hearing loss • Conductive Hearing Loss It is caused by any condition or disease which stop the sound from getting through the middle ear cavity to the inner ear. Also, it can be caused by a damaged ear drum or impacted ear wax. Hearing aid is recommended. • Sensorineural Hearing loss It occurs when damage to the cochlear or the nerve pathways from the inner ear to the brain. Moreover, it can be caused by exposure to loud noise or ageing. Amplification hearing aid is recommended. There are…

Acoustic reflexes are contractions of the stapedius muscle in the middle ear. This reflex occurs when a loud sound is presented to the ear causing the tympanic membrane to stiffen and cause a change in immittance (Martin & Clark, 2012). When measuring the acoustic reflex threshold, we are measuring the softest sound that can cause a reflex of the stapedius muscle as well as the duration of time needed for the reflex to decay. The reflex is presented as a deflection, or a curve/dip, on the…

Trepanation is one of the oldest know surgical techniques. It was practiced in countries all over the world but seems to have originated from places in and around Europe. Trepanning is the process of drilling, grooving, boring and cutting or scraping a hole, usually no bigger than an inch or so, into a person’s head, therefore exposing the dura matter and allowing brain tissue to freely pulsate –increasing blood flow. Figure 1 shows the four methods, 1-scraping 2-grooving 3- boring and cutting…

Why is it that your ears “pop” inside an airplane or when you are driving? Inside your ear there is a pocket of air. this pocket is normally at the same pressure as the air. in a plane, the high altitude means the air is rhinner and although planes are pressured. also, when you swallow and when the pressure is equalised your often feel a pop. Why is it that yawing or chewing gum helps with the ear popping sensation? Yawing or chewing gum helps with the aer popping sensation because…

the way their ears, external or internal, are structures and how each section of their ears function to aid in the process of hearing frequencies from conspecifics. Elephants not only use their large ears to capture frequencies of sound, but they also use fatty cushions in the feet pads to detect vibrations by bone conductions. Whales abandoned their external ears to be able to swim faster, but they have also enhanced their hearing due to the exceptional way…

Two Ears are Better Than One: Microtia Aural Atresia June 26, 2006, the day of my son's birth, I received some shocking news. A nurse informed me that he was born without his right ear, a birth defect called microtia aural atresia. My lack of knowledge on this birth defect made it difficult to understand that babies could be born without their ears. The nurse tried to reassure me that he could still hear because he passed a hearing test. The doctor performs the hearing test by clapping their…

indication that Lucas has an ear infection is that he’s not sleeping well, he hardly eats, and constantly pulling his ear. In children it might be harder to conclude what these symptoms can be exactly since they don’t really speak clearly to actually express what’s bothering them. Chronic otitis media is an inflammation or infection that lies behind the eardrum, it appears and disappears that’s why it’s considered chronic. Some symptoms of otitis media are: sleeplessness, ear pain which causes…
