Background:Hypernasality is a frequently encountered problem in the speech of individuals with velopharyngeal incompetence. The use of palatal lift appliance (PLA) is the main treatment option for correction of velopharyngeal incompetence. The literature on the outcomes of using prosthetics treatment for Arabic speaking patients is scarce.Objective:The aim of this study was to investigate the effect of using PLA on hypernasality of Arabic speaking patients with velopharyngeal incompetence.Methods:Six participants with age ranging from 9 to 61 years (4 males and 2 females) were recruited between October 2013 and August 2014. Written informed consents were taken from all the adult participants/the guardians of under-aged participants. All patients exhibited hypernasality with different etiologies for velopharyngeal incompetence (head injury, cerebrovascular accident, and neurological disorders). They were treated with PLAs which were constructed to elevate the dysfunctional soft palate. Nasalance scores and perceptual speech acceptability ratings were measured/evaluated in both situations; with and without appliances. Paired t-test was used to analyze the perceptual ratings and nasalance scores in order to detect any significant change in hypernasality pre and post insertion of PLA.Results:There was a statistically significant decrease (p>0.05) in nasalance scores (Pa, Pi, Ma, Mi, a, i) after PLA insertion. The subtest /u/ showed insignificant change (p= 0.056). Perceptual ratings showed significant reduction in hypernasality which was consistent with nasalance measurements.Conclusion:PLAs can reduce hypernasality in Arabic speaking patients who suffer from velopharyngeal impairment.

“…Alfwaress et al reported the outcome of palatal lift prosthesis on dysarthria speech, and they concluded that the prosthesis improved the quality of speech during the production of velar syllables such as /ka/. LaVelle and Hardy had 44 patients with a neurological deficit and palatal incompetence who had been treated with palatal lift prosthesis and demonstrated the effectiveness of the prosthesis in patients with pharyngeal dysfunction …”

This clinical report describes the prosthetic rehabilitation of a 25‐year‐old man with a history of grade II chondrosarcoma at the skull base who had undergone surgical resection and thereafter developed velopharyngeal incompetency (VPI), dysarthria, and dysphagia. Upon baseline fiberoptic endoscopic evaluation of swallowing (FEES), the patient had an atypical pattern of VPI with minimal to no velar lift during speech, blow, or suck tasks, but near complete velar lift and seal during swallowing. A palatal augmentation prosthesis combined with a resilient palatal lift extension was fabricated to enhance speech by displacing the soft palate and to decrease hypernasality, while avoiding interference with bolus transport. A resilient wrought wire extension was necessary to accommodate the velar movement upon swallowing while keeping the integrity of the velar lift during speech. In conclusion, this unique combination prosthesis was able to help the patient's atypical pattern of VPI by improving speech and preserving swallowing function, which was confirmed during a post‐endoscopic evaluation.

“…In addition to these studies, others were found about the use of palatal lift prosthesis 27 to improve the dysarthric pattern, which improved the sequential movement rate, speech rate, vital capacity, sound pressure level, intelligibility and reduction of nasality in the studied individuals with ALS; and mouth micro-switch 21 , that showed to be more agile when compared to the optical micro-switch actuated by means of head movement.…”

Purpose: to identify the knowledge produced in national and international researches on speech and language disorders in Amyotrophic Lateral Sclerosis, regarding the type of research and approach in different areas. Methods: an integrative review performed on databases, using the following descriptors: Amyotrophic Lateral Sclerosis, Dysarthria, Language Disorders, Speech Production Measurement and Speech Disorders. The inclusion criteria covered articles that addressed motor speech and language disorders from 2013 to 2018, excluding duplications, and categorizing valid articles for analysis. Results: 83 articles were selected, after screening the titles and abstracts. A large scientific production from different countries and areas, mainly Speech Therapy and Neurology, was found. Most of them was clinical research (65.06%), with a main focus on speech motor disorders (42.16%), speech and language motor disorders, cognition and behavior (27.71%), and language disorders (12.06%). Conclusion: researches found were mostly clinical and aimed at determining the diagnosis of disorders in different areas of knowledge. With regard to communication, few studies have been found in Brazil, and international studies addressed high technology. The results confirmed the heterogeneous nature of the disease, which shows, in addition to motor impairment of speech, cognitive, behavioral and language impairments.

Outcomes of Palatal Lift Prosthesis on Dysarthric Speech

Abstract: The use of PLP is an effective treatment option of dysarthric speech. Besides nasalance scores, the sequential motion rate, speech rate, vital capacity, and sound pressure level are considered reliable speech measures that may be used to evaluate the effect of PLP on dysarthria.
