About Ear
Being one of the five sense organs, the ears play a key role in proper body functioning. They sense the environmental changes around them and within the body that help us to respond to the changes appropriately.
Though the main purpose of the ears is meant for hearing, they also aid to maintain our sense of balance with the help of visual input through the eyes. Here is a brief about various parts of the ears and their functions as well.

The ear comprises of three main parts, namely:
Outer Ear: The outer ear is the external and visible part of the ear. Its main function is to collect the sound waves and direct them to its internal parts.
Middle Ear: The middle ear consists of the eardrum and three tiny bones that connect the eardrum to the inner ear. It also comprises the Eustachian tube which equalizes the air pressure between the inner and outer surfaces of the eardrum.
Inner Ear: It is the highly complex yet essential part of the ear. It has the hearing organ and the receptors that regulate the sense of balance. The intricate network of nerves, canals, bones, and cells in the ear, carry sound waves and equilibrium information to the brain.
Some of the common ear conditions that need expert medical assistance are as follows:
Ear Discharge: Ear discharge is nothing but the draining of fluid from the ear. The ear discharge can include blood, pus, or clear fluid. This can be a result of either infection in the ear or damage to the eardrum. If any ear discharge seems to be abnormal or occurs after a head injury, it should be immediately addressed by an ENT Specialist.
Ear Pain: Ear pain or earache is the most common complaint both in children and adults as well. The main causes of earache can include an injury, infection, or irritation in the ear. Ear pain can be associated with other symptoms as well which vary for children and adults. In adults, the additional symptoms include fever, fluid discharge from the ear, and impaired hearing. While in children, the ear pain can be identified with the presence of a set of additional symptoms which include, fever, difficulty sleeping, irritability, frequent tugging or pulling at the ear, etc. The treatment for ear pain depends on its cause and the patient's age. If the ear pain is due to an infection, the doctor prescribes antibiotics to clear up the infection and improve the symptoms.
Fluid in the ear: Fluid in the ear can be defined as the accumulation of fluid or mucus behind the eardrum, in the middle ear. This can be felt as a blocked ear which can affect your hearing. The fluid in the ear usually occurs when the Eustachian tube in the middle ear gets partially blocked, preventing it from draining the fluid. This may lead to ear infections as the bacteria inside the ear get trapped and begin to grow. Some of the causes that lead to fluid in the ear include; allergies, nasal congestion, chemical irritants, enlarged sinus tissue, damage to the middle ear structures, and rapid air pressure changes. If ignored, fluid in the ear can lead to severe ear infections and causes permanent ear damage.
Ear Wax: Our Ear canal produces a waxy oil kind of substance, often referred to as ear wax. The ear wax protects the internal structures of the ear from dust, foreign particles, and microorganisms. Usually, the ear wax gets washed away by finding its way out of the canal into the opening of the ear. But, when the ear produces more wax than actually necessary, It may become harder and blocks the ear. Also, using the cotton swabs, bobby pins, and other objects to clear the ear wax can push it deeper into the canal and cause ear block. This can lead to temporary hearing loss which can be restored. Besides, excessive and frequent use of earphones may also prevent ear wax from coming out of the canals and causing blockages. Therefore, it is always advisable to get the ear wax cleaned by doctors to avoid ear damage.
Hearing Loss: Hearing loss is common as a process of aging. It is nothing but the loss of a person's ability to hear sounds. Apart from aging, continuous exposure to loud noises can also lead to hearing loss. Hearing loss can be classified into three types based on which part of the ear is damaged. Most types of hearing loss are irreversible, but one's hearing ability can be improved with certain treatment options or using hearing-aid requirements advised by an audiologist.
Ringing in the ear: As the name suggests, sounds related to ringing or buzzing can be heard in the ears and is known as tinnitus. Ringing in the ears isn't a condition itself, but it often indicates an underlying health issue such as an ear injury, age-related hearing loss, or circulatory system disorders. Being exposed to loud noises or a blow to the ear can cause this condition that usually goes away on its own after some time. But, a constant ringing in the ear needs attention and medical assistance to rule out the cause and plan treatment accordingly.
Hole in the ear: A hole in the ear is often known as eardrum rupture or perforated eardrum in medical terms. It is the damage to the tympanic membrane, a thin layer of tissue that divides the outer ear canal and middle ear. When the sound waves enter into the ear, this membrane vibrates. The vibration continues through the bones of the middle ear which allows us to hear. If the eardrum is damaged, a person's ability to hear gets affected. The main causes of eardrum rupture can include injury, ear infections, and activities that cause drastic pressure changes in the ear such as scuba diving, shock waves, etc. In most cases, a perforated eardrum is treated with surgical repair.
Dizziness: Dizziness can be described as a range of symptoms which include being unsteady, lightheadedness, a false feeling of spinning or weakness. Dizziness occurs as a result of a disturbance in one's sense of balance. Our balance is maintained because of the proper coordination of the inner ear, eyes, and brain. So, when this coordination is damaged, the sense of balance gets disrupted and results in dizziness. Also, dizziness can be an indication of many illnesses and conditions which need a medical evaluation to rule out the causes.
Deafness in children: : Deafness in children can be defined as the complete inability of the child to hear sounds. This can have a negative impact on a child's ability to learn language and social skills. Hearing loss in children can often be noticed by delayed speech. Early intervention for hearing issues in children can help with the right treatment at the earliest and can prevent serious impacts, along with promoting language, speech, and cognitive development. The main symptoms which indicate deafness or hearing loss in children include, lack of reaction to loud noises and voices. Deafness in children can be a result of either illness, injury, or birth defects.
