For example, very curvy ear canals, narrow ear canals, or surgical ears are more prone to earwax buildup. When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up ...
Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube.
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
The most common cause of hyperacusis is overexposure to excessively high decibel (sound pressure) levels, which can cause acoustic trauma. [1] An acoustic shock , which can lead to symptoms such as hyperacusis and ear pain, can also occur after exposure to an unexpected moderately loud to loud noise, even if this does not necessarily result in ...
Space heaters also have a hidden hazard: They can cause overheating — aka hyperthermia — especially in kids, people with disabilities and older adults who may have difficulty leaving a room ...
Possible causes are: The "occlusion effect", caused by an object, such as an unvented hearing aid or a plug of ear wax, blocking the ear canal and reflecting sound vibration back towards the eardrum. [1] Serous otitis media; Open or patulous Eustachian tube, allowing vocal or breathing sounds to be conducted into the middle ear
Cerumen keeps the eardrum pliable, lubricates and cleans the external auditory canal, waterproofs the canal, kills bacteria, and serves as a barrier to trap foreign particles (dust, fungal spores, etc.) by coating the guard hairs of the ear, making them sticky. [1] These glands are capable of developing both benign and malignant tumors.
The ear can be exposed to short periods of sound in excess of 120 dB without permanent harm — albeit with discomfort and possibly pain — but long term exposure to sound levels over 85 dB(A) can cause permanent hearing loss. [31] There are two basic types of NIHL: NIHL caused by acoustic trauma; NIHL that gradually develops.
