What Causes Laryngocele?

In rare cases, the internal part of the laryngocele may cause rapid and complete airway obstruction with potentially fatal consequences. Although the incidence of internal laryngoceles is relatively rare, physicians should include this condition in the differential diagnosis of upper airway problems.

How is laryngocele diagnosed?

The diagnosis of laryngocele is based on clinical findings, endoscopic examination of the larynx, and imaging studies. Symptoms may vary according to the type of laryngocele. The internal laryngoceles may cause hoarseness, snoring, or even upper airway obstruction.

How common is a laryngocele?

Laryngoceles are rare (1 in 2.5 million), develop in men more often than in women, appear across all ages, and are divided clinically into internal (expansion into the false vocal fold) and external (extension through the thyrohyoid membrane into the soft tissues of the neck).

How is laryngocele treated?

Conclusion: Endoscopic CO2 laser resection of internal laryngocele provides a reliable and cost-effective method that minimizes hospitalization and the need for tracheotomy. We believe that advances in the applications of laser in microlaryngosurgery will alter the traditional management of all type of laryngoceles.

Is laryngocele congenital?

A laryngocele is a congenital anomalous air sac communicating with the cavity of the larynx, which may bulge outward on the neck.

Where is a laryngocele located?

An internal laryngocele is confined within the false vocal fold, medial to the thyrohyoid membrane. A combined laryngocele extends upward and protrudes through the thyrohyoid membrane to the neck .

Is Laryngomalacia serious?

In most cases, laryngomalacia in infants is not a serious condition — they have noisy breathing, but are able to eat and grow. For these infants, laryngomalacia will resolve without surgery by the time they are 18 to 20 months old.

What is thyroid membrane?

The thyrohyoid membrane connects the thyroid cartilage to the hyoid bone and facilitates the superior movement of the larynx during swallowing. It is separated from the hyoid body by a bursa that facilitates this upward movement during swallowing.

What is congenital Laryngocele?

Congenital laryngoceles are defined as cystic dilatation of laryngeal saccules and are an extremely rare cause of newborn respiratory distress. A laryngomucocele occurs when the neck of the laryngocele gets obstructed and fills with the mucoid secretions of the saccule.

What is a Vallecular cyst?

Vallecular cysts are benign retention cysts of the minor salivary glands. The commonest site is the lingual surface of epiglottis. They distort the epiglottis when they increase in size and eventually fill the vallecula. Blockage of the laryngeal inlet causing severe respiratory distress is an unusual presentation.

What is laryngeal cyst?

Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula. Usually they do not extend to the thyroid cartilage. They may be present congenitally or may develop eventually due to degenerative cause. They often interfere with phonation.

How many larynx do we have?

The laryngeal skeleton is nine cartilages: the thyroid cartilage, cricoid cartilage, epiglottis, arytenoid cartilages, corniculate cartilages, and cuneiform cartilages. The first three are unpaired cartilages, and the latter three are paired cartilages.

What is laryngeal dysfunction?

Vocal cord dysfunction is the abnormal closing of the vocal cords when you breathe in or out. It’s also called laryngeal dysfunction, paradoxical vocal cord movement disorder or paradoxical vocal fold motion.

What is vocal Hyperfunction?

Vocal hyperfunction occurs when the muscles of the larynx work too hard when speaking. The condition can be brought on by stress, reflux or other conditions.

How do you know if laryngomalacia is severe?

Signs of more severe laryngomalacia include difficulty feeding, increased effort in breathing, poor weight gain, pauses in the breathing, or frequent spitting up.

At what age does laryngomalacia go away?

Laryngomalacia is often noticed during the first weeks or months of life. Symptoms may come-and-go over months depending on growth and level of activity. In most cases, laryngomalacia does not require a specific treatment. Symptoms usually improve by 12 months of age and resolve by 18-24 months of age.

Does floppy larynx affect speech?

Laryngomalacia (larin-go-mah-lay-shia), or floppy larynx, is a common cause of noisy breathing in infants. It generally resolves by itself by the time your child is two years old, and your child will not experience any long-term voice problems.

What is supraglottic squamous cell carcinoma?

Early stage supraglottic squamous cell carcinoma (SSCC) is defined as T1 (tumor limited to one subsite of supraglottis with normal vocal cord mobility) or T2 (tumor invading more than one adjacent subsite of supraglottis or glottis or region outside of supraglottis), with no regional nodal spread .

What is Reinke?

The non-muscle part of the vocal cord, sometimes called the vocal fold, right under its surface, is called Reinke’s space. Swelling in this area is called Reinke’s edema. When the vocal cords are impacted by the swelling, they cannot vibrate in the usual way. That means the voice will sound different.

What are laryngeal muscles?

The intrinsic laryngeal muscles act on the individual components of the larynx. They control the shape of the rima glottidis (opening between the vocal folds and the arytenoid cartilages), and the length and tension of the vocal folds.

Who does a laryngoscopy?

Ear, nose, and throat specialists (also called ENT doctors or otolaryngologists) do laryngoscopies. They can do: an indirect laryngoscopy: The doctor uses a small mirror and a light to examine the larynx and vocal cords.

What is the glottic opening?

The glottis is the opening between the vocal folds in the larynx that is generally thought of as the primary valve between the lungs and the mouth; the states of the glottis are the positions generally considered to characterize the different possible shapes of this opening.

What is laryngeal web?

Laryngeal web is a condition in which your child’s larynx (voice box) contains a layer of web-like tissue. This partially obstructs your child’s windpipe, causing frequent shortness of breath and other symptoms.
