When it comes to the sinuses, the most common issue seems to be excess mucus. When the sinuses aren’t acting as they should and sinusitis (a sinus infection) is experienced, it generally leads to mucus overproduction and this can be a difficult issue to live with. However, as many will tell you, dry sinuses are an equally difficult problem.
During the colder months especially, we tend to look towards artificial sources of heat to stay warm. With a pellet stove, for example, we’ve found a solution that keeps costs to a minimum while also not getting too hot for any children or pets in the house. However, one of the biggest benefits of this system is also one of its greatest downfalls.
Back in the day, people would keep a pot of water on the stove to keep moisture in the air. Today, we’re doing the opposite because the stoves are sucking all the moisture from the room for every second they’re working away. For many, this lack of humidity dries the sinuses and causes all sorts of problems as a result.
Is This a Problem?
First and foremost, having dry sinuses is unpleasant so it quickly becomes uncomfortable. The longer the problem goes untreated, the bigger it becomes. Additionally, the sinuses need moisture because bacteria, fungi, and viruses are normally kept at bay by a protective layer of mucus. If this mucus has disappeared, the protection does the same and the sinuses are left vulnerable.
As you may know, this all leads to many problems, one of the biggest being a lack of smell. At first, people tend to attribute the loss of smell to something else because they can’t imagine that a stove (or any other source of artificial heat without the ability to keep moisture in the air) would cause the damage. Soon enough, a medical professional will assess their sinuses and find the problem.
Over the years, people have developed their own solutions for this issue and we have three of the most popular here today. If one doesn’t work for you, try another because the theory behind them is very positive!
- Anti-Fungal Tea: If you’re suffering from a dry nose or dry sinuses, your liquid intake should be increased anyway so long as the liquid is water or any other responsible drink. If you can get your hands on it, there’s also anti-fungal tea and this just might prove to be a fantastic addition to your diet.Known as calendula tea, it comes from the orange calendula flower and offers all sorts of advantageous properties. For example, it acts as an anti-inflammatory, anti-fungal, and antiseptic solution. Alone, the tea should start to improve your sinuses but it becomes even more valuable when partnered with some herbs of your choosing.Since all the ingredients are natural, you can have this tea two or three times in a single day and you should notice a change to your breathing as the day goes on. If this doesn’t work, play around with the herbs you’re using or move on to another suggestion.
- Steam Inhalation and Room Humidifiers: As we addressed earlier, they had a simple solution back in the day and it came from a pot of water. Therefore, why not take from their lead and do the same thing? Nowadays, the market holds some fantastic room humidifiers (and even whole home humidifiers!) to add moisture to the air.If you feel comfortable, you could even try steam inhalation in combination with a neti pot. Before we get ahead of ourselves, steam inhalation is where you hold your face as close to hot water as possible. With a towel over your head to increase the intensity, the idea is to inhale the steam without getting so close you harm yourself. To improve the results, add some essential oils whether this comes from tea tree oil, eucalyptus, lemon, or peppermint. As a starting point, this steam should make the walls of the sinuses a little softer (and looser).From here, you can finish with a neti pot and this is a small container used to rinse any debris you may have from the nasal cavity. With a simple saltwater solution, you leave your sinuses in a great position to become healthy once again.
- Anti-Bacterial Tincture: If you want to fight infection and improve your sinuses, we recommend echinacea and boneset as a two-herb tincture. With a little of the tincture added to water, this should allow you to fight active infection. If you’ve never made a tincture previously, there are plenty of guides online that’ll show you how to get it right.
Regardless of which solution you try first, we urge you to keep going even if you don’t see any results the first time. Over the many years of people suffering with this issue, all three of these solutions have fantastic support in the community so they’re worth your persistence. Typically, you’ll notice a change within a few days and you don’t have to contend with the loss of smell any longer!
Quite often, the term ‘sinuses’ is used in relation to certain medical conditions. However, there aren’t too many people who know the role of the sinuses or how they’re made up. Today, our goal is to answer both of these questions so you’re aware the next time the term is used in conversation!
Commonly shortened to ‘the sinuses’, the paranasal sinuses are small cavities filled with air inside the bones of the face; the bones of note are also found in the eyes and nasal cavity. With each sinus, it has a name that represents the bone in which it can be found.
- Frontal: With one per side, the frontal sinuses can be located in the forehead right above the nasal bridge and eyes.
- Maxillary: Found on each side, the maxillary sinus is inside the bone in the cheek.
- Ethmoid: With the ethmoid sinuses, they sit just under the corner of each eye where the bone lies. In many medical diagrams, they’ll show the ethmoid sinus as one sinus but it’s actually made up of several smaller sinuses in a honeycomb shape; it can only be seen properly in CT scan images of the face.
- Sphenoid: Again, the sphenoid sinus is located on both sides but this time behind the ethmoid sinuses. When looking head-on, they won’t be visible so a side view is required instead.
Physiology of the Sinuses
For each sinus, pink membrane will line the outside and it’s responsible for producing mucus to flush the sinus cavities. With a plate of bone and cartilage commonly known as the nasal septum, the two nasal passages are separated. However, the biology of each passage is the same starting with three small ridges of tissue which can be called a concha or turbinate. Depending on whether it’s referring to the upper, middle, or lower structure, they’re designated as superior, middle, or inferior.
When it comes to the draining, the majority of sinuses use the middle turbinate and the drainage occurs below this point. From here, it goes into the osteomeatal complex. For the system to work correctly, air needs to flow uninterrupted through both sides of the nasal passage since this allows for streaming between the nasal septum and turbinates (via the crevices).
For both the mucus and the airflow that started the process, they should end up in the nasopharynx which is a connecting part of the throat towards the back of the nose. As air continues its journey through the windpipes and into the lungs, the mucus takes a different journey and is swallowed instead.
Structures within the Nasal and Sinus Tract
As you probably know, the human body is quite simply amazing and evolution has allowed it to survive on a day-to-day basis using complex scientific principles. Therefore, it probably won’t surprise you to hear that there are some fascinating structures inside the nasal and sinus tract. Below, we have three very important examples:
- Adenoids: As a collection of tissue much like the tonsils, the adenoids are found behind the farthest nasal cavity accessible at the very top of the nasopharynx. While most body parts and important features of the body grow as we get older, this tissue actually starts larger and then disappears during puberty. However, discrepancies in this process can leave it in tact which has the potential to require surgery.
- Tear Duct: Often called the nasolacrimal duct, this is important for our eyes since, without it, tears would continue to build on the inside corners. When it’s in place and functioning as expected, the tears drain into the nasal cavity and this prevents excess moisture within the eyes.
- Eustachian Tube: As our last example, the eustachian tube is required for removing any build-ups that occur within the ears; with the system all interconnected, the opening is found towards the back of the nasopharynx sidewall.
The Role of the Sinuses
Ultimately, the sinuses have many responsibilities within the ear, nose, throat, and beyond but their main role is to produce mucus. When the system is working as it should, the mucus creates a lining on the inside of the nose and this keeps it free from bacteria, fungi, and viruses. If you were to experience dry sinuses, the lack of mucus would leave the nose vulnerable to these pollutants and this leads to irritation and illness.
Over time, cilia, which are tiny hair cells, gradually move the mucus backwards towards the throat where it’s swallowed. Therefore, the steady supply of mucus always takes the same journey while protecting your nose and remaining clean at all times.
After this main function, we should also note that the sinuses are also important for our voices and to lighten the skull. With everything having a purpose, we’re able to enjoy life without consciously worrying about replacing the mucus or producing the right amounts at the right times. As we learn more about the sinuses and how they work, we get an insight into just how fascinating the human body can be!
Single-sided deafness, or SSD, is a condition in which a person has good hearing in one ear, and non-functional hearing in the other ear. By ‘non-functional hearing’, it is meant that even with the help of some system of sound amplification, the bad ear cannot be made functional again. The most common reason for this is that a person with SSD has sustained damage to the inner ear, so amplification has no effect whatsoever on hearing ability in that ear.
Problems Presented by SSD
One of the most serious issues presented by single-sided deafness is the loss of spatial hearing. Spatial hearing allows a person to identify sounds both distant and nearby, in addition to all those that occur within 360° of the head area. Because our two-tiered auditory system is oriented to evaluate very specific information that can localize and pinpoint sounds, there is a big loss sustained when one ear is completely subtracted from that model.
It creates some difficulties for the brain, in terms of evaluating the information it receives and trying to assess what kind of information is missing. When the non-functional ear is in the acoustic shadow of the functional ear on the other side of the head, there can be significant difficulty with interpreting speech and other sounds, versus normal background noises.
This is especially true when speech or other distinctive sounds reach the non-functional ear first, and are not really ‘heard’ until the sound signal travels around to the other side of the head, to be received by the good ear. The net effects of this kind of sound reception are: a serious degradation in listening quality, difficulty with the interpretation of sounds and speech, and in a broader context, lowering of a person’s quality of life.
Another of the difficulties with single-sided deafness, alluded to above, is the condition known as ‘head shadow’ effect. What is meant by head shadow effect is a situation where sounds originating on the side of the head where the non-functioning ear is, are actually obstructed by the head itself in traveling to the other side of the head where the good ear is.
The main problem with this is that some kinds of sounds become very difficult to hear with the good ear. Low-frequency sounds are mostly unaffected in this scenario, because they have a long wavelength and they can move around the head more readily to the good ear. High-frequency sounds on the other hand, are characterized by much shorter wavelengths, and many of these are typically reflected by the head, and become altered before they reach the good ear.
Since consonant sounds occur largely in the high-frequency wavelengths, this can have a big impact on communication, because it is much more difficult to differentiate those sounds from background noises. Therefore, the biggest impact of this head shadow effect is on communication, and it causes a person with SSD to miss a great deal of what may have been said by someone, even if they’re standing close by.
Causes of SSD
One of the more common causes of single-sided deafness occurs is when surgery is necessary to remove a tumor growing in the ear. This kind of surgical removal sometimes causes such damage to the auditory nerve that a patient loses most or all hearing in that ear. If such tumors are not removed, they will continue to grow slowly, and will eventually cause damage to the ear anyway, including possible loss of hearing. However, surgical treatment can end up being just as harmful, if the auditory nerve becomes damaged.
A secondary cause of SSD is known as sudden idiopathic hearing loss, which is generally attributable to some kind of viral infection. In this scenario, a virus infects the cochlea, which eventually leads to swelling and permanent damage to the delicate structure of the cochlea. It happens fairly frequently that the ear cannot recover from this kind of damage, and the person is left with no hearing in that ear.
A third cause for SSD stems from some kind of blunt trauma to the head. In such cases, there can be a transverse fracture of the critical temporal bone, which has the effect of rendering the cochlea non-functional from that point forward. It is also possible for people to be born with hearing loss in one ear, while having perfectly good hearing in the other ear.
Solutions for SSD
One of the most effective solutions for SSD is known as a Contralateral Routing of Signal (CROS) configuration, in which a microphone is placed in the non-functioning ear, and transmits received sound signals over to a receptor in the good ear. The first of these configurations relied on a tiny wiring system for the transmission of sound between ears, but this has now been improved and refined with a wireless system that makes the whole arrangement less bulky and more effective.
There are now also two additional high-tech solutions which build upon the idea that sound received on the non-functioning side is somehow transported to the good side so that relatively normal hearing is possible. These two processes are known as bone conduction solutions and bone anchored solutions.
In the first, sound is actually transmitted through the bone of the skull to the other side of the head, and in the second, sound is transmitted by a subcutaneous implant which transmits sound through the skin to the good ear. As you might expect, these solutions can be relatively costly, but they can also be a very effective means of restoring normal hearing to someone who has completely lost hearing in one ear.
