Speech therapy will not correct velopharyngeal insufficiency. The condition results from abnormal structure and requires physical management (surgery, or a prosthetic device if surgery cannot be done). Speech therapy is appropriate to correct the compensatory articulation productions that develop as a result of velopharyngeal insufficiency.
Pharyngeal flap surgery may be able to improve speech performance in children or adults with a cleft palate who have velopharyngeal insufficiency. In fact, there is a high success rate for improvement of speech following pharyngeal flap surgery. However, surgery does not guarantee perfect or 100% intelligible speech.
A common method to treat Velopharyngeal insufficiency is pharyngeal flap surgery, where tissue from the back of the mouth is used to close part of the gap. Other ways of treating velopharyngeal insufficiency is by placing a posterior nasopharyngeal wall implant (commonly cartilage or collagen) or type of soft palate lengthening procedure (i.e ...
This type of surgery is best for patients with velopharyngeal defects. (Peterson-Falzone et al., 2001) Cartilage implants: material, (usually from the patient's rib), is implanted to create an anterior projection on the pharyngeal wall.
Hypernasal speech is a disorder that causes abnormal resonance in a human's voice due to increased airflow through the nose during speech.It is caused by an open nasal cavity resulting from an incomplete closure of the soft palate and/or velopharyngeal sphincter (velopharyngeal insufficiency). [1]
Velopharyngeal insufficiency (VPI) can occur as a result of an unrepaired or repaired cleft lip and palate. VPI is the inability of the soft palate to close tightly against the back of the throat during speech, resulting in incomplete velopharyngeal closure. In turn, this results in speech abnormalities.
Pharyngeal Flap Surgery. The superiorly based or inferiorly based pharyngeal flap surgical procedure offers an alternative to the fabrication of a palatal lift prosthesis. A pharyngeal flap surgery unites the posterior pharyngeal wall and the soft palate to definitively occlude the midsagittal aspect of the palatopharyngeal port while ...
difficulty maintaining intra-oral air pressure and velopharyngeal closure during speech; patient has known or suspected abnormality of palate or velopharynx; and, patient is being considered for pharyngoplasty, maxillary advancement or speech prosthesis.
