Tags: Ear Cleaning   Earwax  

Contrary to what you might think, earwax is actually beneficial for protecting your ear from infection. It lubricates and keeps the ear canals clean of bacteria and dirt. Ears are typically self-cleaning, so you shouldn’t have to clean your ears regularly (and in some cases ever); however, sometimes your ears can use a little help. If you are dealing with an earwax blockage, or you are prone to blockages, you will most certainly want to turn to an otolaryngologist to find out the cause of these recurring blockages and ways to keep your ears clean.

Most people use cotton swabs when they clean their ears. The problem with this is that it often serves the opposite purpose, and just pushes the wax further into the ear canal. Using a cotton swab inside the ear can also lead to damage to the ear canal or eardrum. Again, if earwax buildup is a common problem for you this is something you should talk to your ENT doctor about. A simple rule to follow: Cotton swabs should be off limits for cleaning your ears.

Cleaning Your Ears at Home

If you are dealing with a blockage you may be able to remove the earwax yourself with these gentle measures. First, you will want to soften the wax. There are over-the-counter products with a special glycerin solution that can help to breakdown the wax. You can also choose to fill an eyedropper with baby oil or hydrogen peroxide and apply a couple of drops into the ear.

You will want to leave the oil in your ear for up to two days before squirting warm water into the ear canal using a rubber syringe. Again, this syringe can be found as part of an over-the-counter wax removal kit at your local drugstore. Once you have rinsed out the ear make sure to use a towel to dry the outer part of the ear only. If you are prone to ear infections you may want to use a blow dryer to gently dry the ear.

Earwax Impaction

Since everyone’s ears are shaped a little differently this means that the cleaning method that works well for one person might not work as well for another. If you have excess buildup of earwax you may notice:

  • Ear pain
  • Fullness or ringing in the ears
  • Muffled hearing
  • Dizziness

If you wear a hearing aid you may be prone to earwax buildup, so it’s important that you talk with your ENT doctor about ways to reduce your chances for developing impacted earwax. In some cases, doctors may recommend coming in every six months or once a year so they can remove excess earwax safely and effectively without causing damage to the ears.

The middle ear is an air-filled cavity that has many different parts. It consists of:

  • Eardrum
  • Two middle ear muscles -
    • Stapedius muscle
    • Tensor tympani muscle
  • Eustachian Tube
  • Auditory Ossicles (middle ear bones) - 
    • Malleus (hammer)
    • Incus (anvil)
    • Stapes (stirrup)

Functions of the Middle Ear:

  1. Match the low sound resistance of air to the high sound resistance of cochlear fluids – Sound enters the ear as a pressure disturbance of air. Our organ of hearing, the cochlea, is a fluid-filled organ. For those of us who have tried to talk underwater while swimming, we know that sound does not pass through water well. Because of this, the bones of the middle ear function as a lever system in order to make sounds louder, and therefore more audible.
  2. Protection – We have two muscles in our middle ear. These muscles contract in the presence of loud sounds. This stiffens the movement of the middle ear bones in order to protect our hearing.
  3. Pressure Equalization – The Eustachian tube is a small canal that opens and closes when we swallow, yawn, and chew. When the Eustachian tube opens, it equalizes the pressure in the middle ear space to match that of the environment that we are in.

 

What can go wrong in your middle ear?

  • Otitis Media – Fluid build up in the middle ear space can either be infected or not. Either way, it impacts the movement ability of the auditory ossicles, hindering our ability to hear. When fluid in the middle ear becomes infected, our ears can become very painful and can sometimes result in a fever or a perforated ear drum.
  • Negative Pressure – Allergies, coming into or out of an ear infection, and going up or down in elevation can cause our ears to become pressurized, especially if we cannot naturally equalize the pressure between our middle ears and our outside environment. In these cases, it is common to feel as though we need to pop our ears.
  • Perforated Eardrum – A hole in the ear drum can occur from ear infections or trauma. Trauma can occur from very loud sounds, quick and extreme pressure changes, and physical impacts such as a Q-tip hitting the eardrum. Often times, perforated ear drums heal on their own; however, in some cases, surgical intervention may be needed based on the size or location of the perforation in the eardrum.
  • Cholesteatoma – A cholesteatoma is a collection of dead skin cells and debris that builds up in a retraction pocket of the eardrum or middle ear space. These are common in people who have had a history of multiple repeated ear infections, eardrum perforations, ear surgeries, or a familial history of cholesteatomas.
  • Otosclerosis – Otosclerosis is an abnormal growth on one or multiple of the auditory ossicles (most commonly on the stapes). This prevents the auditory ossicles from vibrating freely, hindering a person’s ability to hear appropriately. Depending on severity, otosclerosis is treated by routine monitoring and use of a hearing aid or surgical intervention.
  • Mastoiditis – Mastoiditis is an infection of the bone in which the middle and inner ears are located. This is often a result of untreated middle ear infections and can be very serious if not treated promptly.

 

Fun facts about the middle ear:

  • The space of your middle ear is approximately the size of a dime.
  • The auditory ossicles are the smallest bones in the human body.
  • Middle ear infections are more common in children because their Eustachian tubes lie perpendicular to the ground, hindering their ability to open and close properly. As we grow, our Eustachian tubes grow into a 45-degree angle with the ground, making it easier for them to open and close more freely. 
  • Hearing loss that has its origin in the middle ear system is often able to be medically managed or monitored. Furthermore, this type of hearing loss affects the volume of sound and not its clarity, allowing patients to be very successful with a hearing aid(s).
 

Welcome to the first of a four part series on the different parts and purposes of the ear. Lets start by talking about the outer ear!

The outer ear consists of two parts, the auricle or pinna (the part that you see when you’re looking at the ear) and the external auditory canal.

Your outer ear isn’t just an earring holder. It also has several functions that contribute to our hearing and well-being.

  1. Protection - Your ear produces a bitter-tasting waxy substance in order to keep bugs at bay. It also has hair in order to prevent dirt and pollen from reaching your ear drum.
  2. Amplification - Your ear has a resonant frequency (pitch), meaning that it functions at its best between 1000 and 4000 Hz. Because of this, for sounds that fall within this range, there is approximately a 15-20 dB increase in volume. Luckily, this is the frequency range that most speech sounds are located.
  3. Localization of sound - The patterns of the folds of your auricle create inaudible echoes when sounds hit it. These echoes blend with the original sound, helping the ear decipher where a sound is coming from.

 

What can go wrong with your outer ear?

  1. Impacted ear wax – Impaction of ear wax has two different causes: over production of ear wax and ear wax being pushed into the ear by the use of Q-tips. Either of these issues results in sound not being able to reach the ear drum properly, hindering your ability to hear appropriately.
  2. Foreign bodies – These can include bugs, cotton left over from a Q-tip and any other small object a child could put in their ear (i.e., beads, peas, toy pieces, rocks, etc.)
  3. External Otits (also known as Swimmer’s Ear) – Swimmer’s Ear is an ear infection of the outer ear that is often caused by leftover water in the ear canal, allowing bacteria and fungus to grow. This type of ear infection is common in people who go swimming often or who have very bendy ear canals.
  4. Trauma – This can include burning your ear on a curling iron, getting cauliflower ear from boxing, or a new ear piercing getting infected, just to name a few.

 

Fun Facts about the Outer Ear:

  • Your ear canal is about an inch long.
  • Your auricle or pinna never stops growing.
  • Your ears are naturally self-cleaning. The hair in your ears helps the ear wax that you produce work its way out of your ear naturally.

Tags: Nosebleeds  

Nosebleeds happen to most of us at some point during our lifetime. While it can be startling, nosebleeds are typically harmless and nothing to worry about. Of course, if you battle nosebleeds rather regularly you may be wondering what’s going on and whether you should turn to an otolaryngologist for an evaluation. Here’s what you should know about getting a nosebleed.

Common Causes of a Nosebleed

The blood vessels within our nose are very delicate, which means that they are prone to bursting and causing nosebleeds. Therefore, the two most common causes of nosebleeds are nose picking and dry air. Dry air can dry out the nasal passages, which leaves the area prone to infection and cracking.

Other causes include:

  • Repeated nose blowing
  • Allergies
  • Broken nose
  • Acute or chronic sinusitis (a sinus infection)
  • Common cold
  • Irritants
  • Certain allergy medications (these medications can dry out the nose)
  • Traumatic injury to the nose
  • Deviated septum
  • Bleeding disorders
  • High altitude
  • Excessive use of blood thinners or anti-inflammatory medications

There are two main types of nosebleeds: anterior and posterior. An anterior nosebleed is a bleed that originates in the septum of the nose (the wall that separates the two nasal passages). These nosebleeds are minor and can be treated with home care. If your child experiences nosebleeds an anterior nosebleed is usually the cause.

Posterior nosebleeds occur further back in the nose where the artery branches are located. This type of nosebleed is much heavier, occurs more often in adults and may require medical care. While rare, it is possible for a posterior nosebleed to be a sign of high blood pressure or a blood disorder (e.g. hemophilia).

When to See a Doctor

While most people will be able to treat a simple nosebleed on their own without having to seek medical care, it’s important to see a doctor right away if:

  • Your nosebleed is affecting your ability to breath
  • Bleeding lasts more than 20 minutes
  • Your nosebleed is the result of a traumatic injury or accident
  • There is a significant amount of blood

While it’s not considered an emergency situation, it is a good idea to talk with your ENT doctor if you or your child experiences nosebleeds often. During an evaluation an ear, nose and throat doctor can ask you questions about your symptoms, perform a quick examination of the nose and determine the underlying cause of your persistent nosebleeds.

If you are concerned about you or your child’s nosebleeds then it’s best to play it safe and to schedule an appointment with an otolaryngologist. Call our office today.
