Turbinate Hypertrophy

    What Is Turbinate Hypertrophy?

    Turbinates are two spongy curled bones that protrude into the nasal passages. They are located bilaterally on both sides of the nasal cavity and are separated by the nasal septum. Turbinates are covered by respiratory epithelium covering a thick layer of vascular tissue. Anatomically, the structures are layered from near the floor of the nose to the top of the nasal cavity and are referred to as the inferior, middle and superior turbinates. The inferior turbinate is the largest and functionally most important turbinate.

    Turbinates are responsible for conditioning the inhaled air

    The turbinates are responsible for directing the airflow inside the nasal cavity. The name “turbinate” actually comes from the word turbulence- meaning the irregular flow of water or air. Respiratory epithelium covering the turbinates plays an important role in humidifying, heating and filtering the inhaled air. Humid air helps to prevent potential damage to delicate olfactory receptors located in the nasal cavity. These receptors are responsible for the recognition of odors. The epithelium also represents the first line of immunological defense providing access to the lymphatic system. This is a place where immune-competent cells reside. The cells trigger a quick immune response in the form of an inflammatory reaction at the signs of microbial or chemical irritation.

    Turbinate hypertrophy can develop in response to various environmental factors and infections

    snoring

    Snoring is one of the most common symptoms of turbinate hypertophy (enlarged turbinates).

    Mucosal membranes covering the turbinates contain a large supply of blood vessels and can easily shrink or swell in response to various factors. As a result, turbinates can expand due to allergies, chemical or physical irritants, temperature changes, or acute sinus infections which will congest the nose. This enlargement is reversible and turbinates normally will return back to normal size. However, persistent inflammation, allergic reactions and exposure to various environmental irritants may lead to the chronic swelling of the turbinates (usually inferior turbinates), resulting in a condition referred to as turbinate hypertrophy. Enlargement of the turbinates results in difficulty breathing through the nose. Troubles with breathing at night and snoring are common in such cases. Also, turbinate hypertrophy is associated with chronic sinus infections and nosebleeds that can potentially stem from an untreated deviated septum.

    Common Signs And Symptoms

    Some of the symptoms of nasal turbinate hypertrophy include:

    • Altered sense of smell
    • Forehead pressure and facial pain
    • Chronic nasal congestion
    • Runny nose
    • Snoring

     

    Nasal Turbinate Hypertrophy Risk Factors

    Common risk factors of nasal turbinate hypertrophy include:

    • Living in an urban dense population
    • Constant seasonal change
    • Constant temperature changes

     

    Septal Deviation Can Lead To Turbinate Hypertrophy

    The nasal septum is a structure made of bone and cartilage that sits between the two nostrils and separates the nasal cavities into a left and right side. A perfectly straight nasal septum is rarely ever seen. Significant deformity of the nasal septum, either congenital or traumatic, can lead to compensatory turbinate hypertrophy on the opposite side of the deviation. It is rather common for doctors to see patients who have one side of the nose blocked due to a deviated septum, and the other side obstructed due to hypertrophy of inferior turbinate.

     

    Treatment Of Turbinate Hypertrophy

    Removal of irritating factors or treatment of underlying allergies can diminish the swelling of turbinates. Nasal steroid sprays can reduce mucosal inflammation and improve nasal breathing caused by turbinate hypertrophy.

    However, when the bony structure of turbinates is enlarged, a surgery addressing the underlying problem may be required. Turbinoplasty (turbinate reduction) aims to reduce the size of the turbinates to help open the nasal airways. It can be performed in conjunction with rhinoplasty (correction or reconstruction of the nose) or septoplasty (straightening of the septum).

    There are several surgical techniques that can be used to reduce the size of the turbinates. Some methods involve the removal of some of the turbinates’ bony structure, while others help to achieve the shrinkage of turbinates by reducing the existing soft tissue. One of the commonly used techniques, radio-frequency reduction, relies on heating up a part of turbinates using a special electrical device.  The heated tissue gradually become scarred which helps in reducing the size of turbinates. Another technique is stereotactic image-guided surgery, which uses noninvasive three dimensional diagramming.

    Seek treatment for the underlying cause of your turbinate hypertrophy…and enjoy a peaceful night’s rest.

    Turbinoplasty involves making an incision at the mucosa lining of the turbinates and removing a section of the bony structure. A device called microdebrider is commonly used for this procedure. This device drastically reduces the surgical time needed. A partial turbinectomy involves surgically removing the forward end of the inferior turbinate, thereby removing a portion of both the bone and mucosa.
