    Smell and taste recovery techniques for laryngectomees

    Patients who undergo treatment for laryngeal cancer (total laryngectomy) are called laryngectomees. You will learn various cares and information that should be remembered, so that your surgical intervention is totally effective and healing is not traumatic. Also you will learn some smell and taste recovery techniques.

    After surgical operation, taste and smell are lost.

    The air stops going through the nasal cavity, in which there are sensory tissues (epithelium) that are mainly responsible for smell and have an essential function in taste.

    There are ways to learn to smell and taste once again completely and have a better quality of life.

    Problems with smell (called olfactory disorders) can impact your hunger, taste, satisfaction of food, and the quantity of food you consume.

    Almost all people who have had a laryngectomy discover that they can not smell things the way they used to. This is so because the air no longer goes through the nose.

    With olfactory rehab, you can be taught methods that trigger nasal airflow and that can help you regain your sense of smell.

    Examples are the nasal airflow induction maneuver and the “polite yawn” technique.

    Individuals who have actually gone through surgical treatment cannot smell if they do not find out how to make air pass through their nostrils.

    In this sense the sense of smell is important for lots of acts of everyday life, such as finding a gas leak or a fire. Here are some smell and taste recovery techniques.

    The operation does not impair smell at all. However, because the air ceases to pass through the nose, where the sense of odor lies, it does not naturally return.

    Nevertheless, some smells remain quite distinct, like tobacco, gasoline, and others. This indicates that our sense of smell has not been entirely lost.

    To prevent atrophy over time, we need to perform exercises that encourage air to pass through the nose to the mouth, thus promoting smell

    To experience what this resembles, a non-laryngectomized individual can put a jellybean in their mouth, holding the nose shut. Chew the jellybean as typical.

    You will observe the sweetness, however the flavor (orange vs grape for example) is difficult to inform.

    Then launch the nose and breathe in. Suddenly, the flavor ends up being obvious. Losing the ability to inhale through the nose accounts for the significant change in taste following surgical treatment.

    Exercises

    The strategy the speech pathology personnel will teach you is likewise described is the “polite yawn technique”.

    It works to assist air move through your nose, and by doing this, will also enhance your capability to taste more properly.

    Lots of laryngectomees have actually reported this makes foods taste more “normal.”

    In spite of discovering this maneuver, you may still not feel as though foods taste as it did before your surgical treatment.

    With time, however, normally within the first 6-9 months, a lot of laryngectomees feel as if their food taste is “normal” again.

    One exercise is practical and very simple.

    It includes putting a mirror under the nostrils and blowing the nose, letting the air come out of it, up until the mirror is fogged up with the mist.

    At first it will fog very little or not at all, but with time we will see that it is increasingly more foggy.

    It can be made with both nostrils at the same time or by covering one and the other alternately.

    Nasal airflow induction is a strategy that enables healing of odor and enhancement of taste in laryngectomized individuals.

    It is simple to carry out and discover. It does not need pricey technical ways.

    Healing odor and taste enhances life quality. Thus, it’s crucial to include this in laryngectomy patient rehabilitation protocols.

    After an overall laryngectomy (the treatment for laryngeal cancer) everyone needs to take several unique cares into account.

    Devices

    One gadget that has been utilized to restore olfactory function in these patients is the larynx bypass.

    Using the device daily for 30 minutes at home for three months improves olfactory function significantly (Sniffin’ Sticks test).

    Subjective improvement can be seen after 1 week.

    Practicability ratings enhanced statistically, however the gadget stayed hard to utilize. There hasn’t been formal long-term study of throat bypass use. We hope our findings will provide a foundation for further investigation.

    Taste

    Taste is not directly impacted by the operation, unless it involves partial or total removal of the tongue.

    As odor and taste are carefully connected by not smelling, the taste loses strength. That is why the significance of not letting the odor atrophy too much.

    Taste will likewise be impacted since it is closely related to smell. Ask him how to prepare the food so that it tastes better.

    Additionally, many laryngectomees undergo multiple radiotherapy sessions, particularly in the neck and mouth, which directly impacts taste.

    Taste can likewise be stimulated so that it does not lose strength.

    You can attempt different types of food or drink by enjoying it in your mouth like a jury would in a gastronomic contest.

    After surgery, taste and smell are lost.

    When air no longer passes through the nasal cavity, it affects the sensory tissue (epithelium) responsible for smell, which is also vital for taste.

    Olfactory disorders, known as smell issues, can affect your appetite, taste perception, food enjoyment, and food intake volume.

    Smell isn’t impaired by the operation. However, because air no longer passes through the nose, where the sense of odor is located, it isn’t stimulated. When smell is lost, taste weakens due to the close connection between the two.

    Our sense of smell is incredibly sensitive. Only a few odor molecules reaching the olfactory epithelium can transmit signals to the brain, distinguishing numerous smells.

    Sensitivity decreases with age, but barring anatomical dysfunctions or external irritations, it generally remains intact.

    Taste, although independent of smell, is enhanced by it. The nerve connection from the tongue’s papillae shares the same brain receptor center, enhancing the taste experience through this synergy.

    Just as papillae receive flavor molecules through saliva, smell requires molecules to enter the nose upon contact with the air and the cilia.

    Understanding Taste and Smell Changes After Total Laryngectomy

    Total laryngectomy results in the upper airways remaining inactive when breathing through the stoma. This means that air no longer enters or leaves through the nose, and salivation also decreases.

    As a consequence, anosmia or hyposmia, which are the loss or decrease in the uptake of odors, can occur. A weakened sense of smell can enhance taste, possibly causing conditions like ageusia or hypogeusia, signifying taste loss or reduction.

    Typically, taste isn’t lost but is diminished and altered without smell, especially during radiotherapy and chemotherapy treatment.

    However, in general it is recovering well for the simple act of eating.

    However, some flavors may become heightened, while others decrease, and this effect often normalizes with time.

    Some individuals still exhibit hypersensitivity to salty and spicy flavors. Drinking wine can lead to a strong alcohol burn sensation with minimal wine taste perception for some individuals.

    To restore salivation, drink water, reduce dairy intake, chew, talk, think about tasty foods, and respond to food-related visual stimuli. Additionally, capturing odors can reactivate nose airflow. Many laryngectomees retain some olfactory function, perceiving strong odors, despite not experiencing complete atrophy of the olfactory system.

    Yet, without a system to induce airflow through the upper respiratory tract, allowing odorous molecules to reach the olfactory epithelium, atrophy can become irreversible.

    Normally the problem of anosmia is that it is not paid attention to.

    What is worse, everything suggests that people do not know that its treatment is simple and effective.

    And that it would have to be part of the rehabilitation of laryngectomy performed by speech therapists.

    Many laryngectomees lack speech therapy, which is typically provided by dedicated and compassionate professionals, often women.

    “I started the recovery of the sense of smell precisely because of the performance of Eulalia Juan, already mentioned. The Son Llàtzer Hospital speech therapist taught the “polite yawn,” checked its efficacy with a manometer, and designed smell exercises.

    And it was she who told me where I could find exhaustive information on the Internet method for the recovery of smell that had been started in Holland.

    Unlocking the Potential of Anosmia Treatment: The Role of Speech Therapists and Simple Techniques

    From what we had experienced with Eulalia Juan, I began to do my tests. I conceived a simple manometer, thinking that a tube could connect the trachea to the mouth, restoring nose breathing quickly.

    If the nasal pituitary system recovers when odorous molecules reach it, what you have to do is activate the volatile circuit of the nose.

    It is almost impossible to find a permanent activation mode, but it is easy to breathe periodically with the tube that connects the trachea to the mouth.

    A tube that can be that: a simple tube flexible, or a silicone tube with specific adapters for the mouth and stoma.

    A gadget that later I have seen that is called a “laryngeal bypass” and that is even among the clinical accessories.

    It is also possible at any time and place to perform the polite yawning.

    It’s evident that sporadic exercise isn’t sufficient. Persistent nasal airflow activation may also benefit speech by stimulating air injection into the esophagus.

    “The laryngeal by-pass, as described by otolaryngologist José Manuel Morales Puebla, is a tube connecting the tracheostoma to the mouth. This allows air to enter through the nostrils when inhaling.

    From there it would pass to the mouth and from the mouth through the tube into the lungs.

    On exhalation the air would do the tour inverse, in this way, a nasal airflow is generated that allows the odorous particles to stimulate the olfactory epithelium.

    The nasal airflow induction technique involves creating negative and positive pressures in the oral cavity through mouth movements. These pressures are transmitted through the rhinopharynx to the nostrils. This achieves the entrance and exit of air from them.

    During the initial training, we checked the correct technique performance using a water manometer. We used a ‘U’-shaped tube with colored liquid, placed in a supportive base for stability.

    One end of the tube is connected to the nostril and the other end is free.

    The other nostril must be occluded.

    When performing the nasal airflow induction maneuver, negative and positive pressure is generated in the oral cavity are transmitted to the nose. From there to the tube and to the pressure gauge.

    Reclaiming the Sense of Smell: Anosmia Treatment and Its Simple Solutions

    All the experimentation carried out by these simple and non-invasive maneuvers gives highly satisfactory results: evidenced by the work carried out and documented by Dr. Morales and the speech therapist Glòria Vich especially on the rehabilitation of smell. The Practices and exercises are progressively increasing and resuming the normality in the capture of odors and distinction of aromas.

    Glòria Vich, states: «Normally this consequence is not mentioned, people with anosmia could feel insecurity in their daily life. 

    For example, don’t smell the smoke if there’s a fire, don’t smell the gas if there is a gas leak. They are not capable of detecting bad food or stew’s status, they cannot perceive the body odor, as well as pleasant fragrances such as chocolate, coffee, meat, perfumes»

    Also worth mentioning is what Matilde Otero Losada, from the Laboratory of Sensory Investigations of the Hospital de Clínicas de la UBA and researcher at CONICET, states that smell is related to sensations and memories.

    Anosmia Treatment and Its Remarkable Impact

    The olfactory nerve enters directly in the brain and sends the information to the memory banks that are in the hippocampus. There the objective data is stored, while the amygdala is the one who has memory of the emotions. Smell has an episodic memory, that is, a single smell synthesizes a series of emotions, sensations, people, situation, place, climate.

    For all the above, we must assert the importance of treating anosmia, as it is simple and accessible in its realization.

    Not only does it have to be taught and performed in speech therapy sessions and in rehabilitation centers for laryngectomized patients.

    It is advisable to encourage individual “polite yawn” in daily life and use fresh or dried aromatic herbs, spices, flowers, aromas, shaking them near the nose to stimulate the cilia.

    A very simple and elementary manometer or with a homemade “laryngeal by-pass”, which can be done with a silicone tube of about 30 cm and a bottle nipple for adaptation to the tracheostoma.
