What is the purpose of vallecula?
The epiglottic vallecula is a depression just behind the root of the tongue between the medial and lateral glosso-epiglottic folds in the throat. These depressions serve as “spit traps”; saliva is temporarily held in the valleculae to prevent initiation of the swallowing reflex.
What are the epiglottic valleculae?
The epiglottic vallecula consists of a small mucosa-lined depression (vallecula) located at the base of the tongue just between the folds of the throat on either side of the median glossoepiglottic fold. It is usually not seen by the naked eye as it is far back and deep at the root of the tongue.
Can food get stuck in the vallecula?
When material rolls into the pharynx without a response, the bolus may land in the valleculae, the pyriform sinuses , or airway, depending upon the amount of food given, consistency of the food, and patient’s posture.
Is the vallecula part of the oropharynx?
The epiglottic valleculae are paired depressions in the oropharynx located anterior to the epiglottis and posterior to the base of tongue. They are located between the lateral glossoepiglottic folds and the median glossoepiglottic fold.
What is a vallecula in the throat?
Vallecula is a term that means depression in something. The epiglottic vallecula consists of a small mucosa-lined depression (vallecula) located at the base of the tongue just between the folds of the throat on either side of the median glossoepiglottic fold.
What is a Vallecular mass?
Vallecular mass lesions are uncommon disease entities with benign cysts being the most commonly encountered vallecular lesion by the otolaryngologists. The vallecular cysts are also called ductal cysts, laryngeal cysts, lymphoepithelial cysts, and mucous retention cysts.
What does pooling in Valleculae mean?
Pooling occurs when a person’s swallow does not successfully send the entire mass of food or liquid into the esophagus, so that some or all of the material remains in the hypopharynx. In such cases, the material commonly pools in the vallecula and pyriform sinuses.
Can Vallecular cysts be cancerous?
Vallecular cysts are usually benign in pathology, and expose no immediate danger from a cancer prospective.
What are the symptoms of a Vallecular cyst?
Patients with vallecular cysts often have similar symptoms/signs as those with laryngomalacia.
- Inspiratory stridor is usually present at birth (noisy inhale)
- Feeding difficulties.
- Minimal, moderate or severe respiratory distress.
How common are Vallecular cysts?
Vallecular cyst is a rare cause of upper airway obstruction in infants and children and presentation like acute stridor with near fatal respiratory distress is extremely rare. It is one of the rare causes of difficult intubation, during which cyst aspiration can improve the access.
What is the vallecula?
What are the 4 stages of swallowing?
There are 4 phases of swallowing:
- The Pre-oral Phase. – Starts with the anticipation of food being introduced into the mouth – Salivation is triggered by the sight and smell of food (as well as hunger)
- The Oral Phase.
- The Pharyngeal Phase.
- The Oesophageal Phase.
How common is Vallecular cyst?
Vallecular cysts are rare, representing 10.5-20.1% of all congenital laryngeal cysts [1-2]. The overall incidence rate of these cysts is approximately 3.49-5.3 cases per 100,000 newborns [2-3]. Clinical features include stridor, respiratory distress, poor feeding, and failure to thrive [4-5].
Can a Vallecular cyst be cancerous?
Vallecular cysts are usually benign in pathology, and expose no immediate danger from a cancer prospective. However, with the passage of time, an increase in the size of the cyst might give the patient more symptoms. The treatment for vallecular cyst is surgical.
How is a Vallecular cyst treated?
Treatment. Vallecular cysts need to be decompressed surgically. Surgery is performed endoscopically. Once the airway is secured with an endotracheal tube, the cyst is either marsupialized (widely opened) or removed using either microlaryngeal instruments or a laser.
Is the vallecula a common landmark for intubation?
The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis.
What is the most critical phase of swallowing?
The upper esophageal sphincter returns to its usual closed state after the bolus passes. Safe bolus passage in the pharynx without aspirating food is critical in human swallowing.
What are the signs of dysphagia?
Dysphagia is the medical term for swallowing difficulties.
- coughing or choking when eating or drinking.
- bringing food back up, sometimes through the nose.
- a sensation that food is stuck in your throat or chest.
- persistent drooling of saliva.
- being unable to chew food properly.

What are the 4 stages of dysphagia?
Which nerve is responsible for swallowing?
The vagal nerve (VN), the tenth cranial nerve, provides both motor and sensory innervation, and plays an important role in the pharyngeal phase of swallowing [4, 6].
What are three disorders that cause dysphagia?
Certain disorders — such as multiple sclerosis, muscular dystrophy and Parkinson’s disease — can cause dysphagia. Neurological damage. Sudden neurological damage, such as from a stroke or brain or spinal cord injury, can affect the ability to swallow.
Is vallecula a common landmark for intubation?
What nerve Innervates the vallecula?
The glossopharyngeal or ninth cranial nerve provides sensory innervation to the vallecula (the space anterior to the epiglottis) and the base of the tongue.
