What is the best method of treatment for velopharyngeal insufficiency?

What is the best method of treatment for velopharyngeal insufficiency?

The treatment of velopharyngeal insufficiency or velopharyngeal incompetence usually requires a surgical procedure (tonsillectomy, Furlow Z-plasty, pharyngeal flap, sphincter pharyngoplasty, or posterior pharyngeal wall implant).

What does the Velopharyngeal port do?

The velopharyngeal port or velopharyngeal sphincter is the passage between the nasopharynx and the oropharynx. It is closed off by the soft palate and uvula against the rear pharyngeal wall during swallowing to prevent food and water from entering the nasal passages.

What happens when the Velopharyngeal port is closed?

To produce most speech sounds, the air and sound need to be directed into the mouth and blocked from entering the nasal cavity. This is done through closure of the velopharyngeal valve.

How do you check for velopharyngeal closure?

How is velopharyngeal insufficiency (VPI) diagnosed?

  1. Endoscopy, using a medical device with lights attached that allow doctors to see inside the mouth.
  2. Videofluoroscopy, a type of X-ray that uses a liquid called barium to provide contrast that makes it easy for a doctor to examine the back of the mouth.

How long is VPI surgery?

VPI is commonly present when a child has a history of cleft palate, submucous cleft palate or trauma to the soft palate. It is also present in a variety of birth defects and/or genetic syndromes and can rarely occur following adenoidectomy. The surgery generally takes 1 ½-2 ½ hours.

Who treats VPI?

Velopharyngeal incompetence (VP incompetence) means there is a problem in how the soft palate moves to make speech sounds. It is possible to have more than one type of VPD. A speech and language pathologist (SLP) specializing in VPD will help determine what types your child has.

What are the symptoms of velopharyngeal dysfunction?

Signs and symptoms of VPD may include:

  • Excessively nasal speech quality (also known as hypernasality)
  • Leakage of air through the nose while speaking.
  • Speech which sounds weak or muffled.
  • Abnormal articulation.
  • Leakage of food or liquid through the nose while eating.

How long does pharyngeal flap surgery take?

What to expect after surgery: The pharyngeal flap procedure takes about 1 ½ hours. The child will stay in the hospital for 2 to 5 days. In the first few days after the surgery, the child will have a sore throat that is similar in feeling to when tonsils are removed. In addition, the child may have neck pain.

What can you eat after pharyngeal flap surgery?

Foods may be cooked, chopped, ground, mashed, or pureed. Examples may include: yogurt, pudding, Jell-O, ice cream, cooked vegetables, soft fruits, mashed potatoes, rice, pasta, soups, eggs, and very soft protein sources. seeds, bread with thick crunchy crust, raw or dried fruits and vegetables.

What are the main leading causes of velopharyngeal dysfunction?

What Causes Velopharyngeal Dysfunction?

  • history of cleft palate.
  • submucous cleft palate.
  • 22q deletion syndrome (DiGeorge syndrome)
  • problems with the palate or throat.
  • adenoidectomy.
  • traumatic brain injury or other neurological disorders.

What is the purpose of a palatal lift prosthesis?

A palatal lift prosthesis (PLP) is an intraoral device that provides lift for the soft palate. The usual purpose of a PLP is to reduce nasopharyngeal reflux and the hypernasal speech caused by velopharyngeal incompetence.

What is nasal grimace?

One such mechanism is nasal grimace, which is an abnormal constriction of the nostrils during speech production. This phenomenon occurs as a subconscious attempt to block airflow through the nose when nasal emissions occur.

What muscles open the velopharyngeal port?

The velopharyngeal sphincter comprises the following six muscles:

  • Tensor veli palatini.
  • Levator veli palatini.
  • Uvular muscle (musculus uvulae)
  • Palatoglossus.
  • Palatopharyngeus.
  • Superior constrictor.

What is Velopharyngeal insufficiency?

Velopharyngeal insufficiency (VPI) occurs when the back part of the roof of the mouth (soft palate) and the pharynx (throat) don’t work together to make a good seal when your child is talking. This is often caused by a soft palate that is too short or muscles of the palate that do not work well.

What is palatal augmentation?

The palatal augmentation prosthesis (PAP) was developed in order to improve these individuals’ ability to articulate and swallow. The PAP is an oral prosthesis with an augmentation that lowers the palate. It is placed on the hard palate and attached to the teeth by clasps.

What sounds are affected by VPI?

Velopharyngeal Insufficiency in Children The two main speech symptoms of velopharyngeal insufficiency (VPI) are hypernasality and nasal air emission. Hypernasality is sometimes called nasal speech. In English the sounds “m,” “n” and “ng” are the only sounds that should resonate nasally.

What is obturator in dentistry?

The obturators are prosthesis used to close palatal defects after maxillectomy, to restore masticatory function and to improve speech. The primary goals of the obturator prosthesis are to preserve the remaining teeth and tissue and to provide comfort, function, and aesthetics to the patients.

Is VPI genetic?

The rate of VPI has been documented as high as 33% in some studies with higher rates of recurrences following surgery associated with genetic syndromes such as 22q11. 2 deletions. The primary cause of VPI in these groups is still identified as the anatomic abnormalities of the velum.

How do you clean an obturator?

Obturator Care Use soap and water or denture paste on a brush to remove plaque. Stains can be removed with commercial soaking agents. Clean the obturator over 4-5 inches of water in a basin or sink to avoid damage to the obturator should it drop. Remove the prosthesis at night and place it in a container of water.
