Objectives. Our study aimed to highlight the effectiveness of palatal lift prosthesis in patients with velopharyngeal insufficiency with previous operated cleft palate.
 Methods. This study was done undertaken January 2008 to December of 2009 in the Phoniatic unit of Alnoor Specialist Hospital, Makkah, Saudi Arabia. Ten patients of ≥ 8 years to ≤ 10 years of age, who had previously undergone surgery for cleft palate, with or without cleft lip, with no other systemic illness and normal intelligent quotient level, were selected and managed by palatal lift prosthesis. All the study subjects were subjected to auditory perceptual speech evaluation for assessment of the degree of hypernasality, compensatory articulator mechanisms, glottal and pharyngeal articulation, audible nasal emission, facial grimace and overall intelligibility of speech. Data were analyzed using SPSS version 16. 
Results. The study included 10 subjects whose mean ± standard deviation of age was (8.9±0.9). On auditory speech perceptual evaluation after prosthesis application, significant improvement was found in glottal articulation 6 (85.7%), p=0.04, facial grimace 6 (85.7%) p=0.04, hyper nasality 10 (10%) p=0.008, and speech intelligibility 9 (90%) p=0.008. 
Conclusion. Young patients with repaired palatal cleft have significant improvement after application of palatal lift prosthesis.

Palatal lifting prosthesis and velopharyngeal insufficiency: preliminary report.

Success in Maxillofacial Prosthetics depends on full cognizance of the principles that underlie facial harmony, anchorage and retention, weight bearing and leverage, durability, tissue compatibility and tolerance. The maxillofacial prosthodontist normally provides appliances to restore aesthetics and function to the patients who cannot be restored to normal appearances or functions by means of plastic reconstructions. The velopharynx is a dynamic anatomic structure which is essential for normal breathing, eating, and speaking. The soft palate acts as a separator between oral and nasal cavities. Impairment of velopharyngeal function can be caused by insufficiency or incompetency. This article describes in brief about velopharyngeal defects and their management.

Management of velopharyngeal defects: a review.

Orofacial clefts (OFCs) are common and treatable birth defects. The etiologies of facial clefts include hereditary, environmental, and multifactorial causes. The role of dentistry in treating individuals with cleft and craniofacial anomalies is to provide comprehensive preventative and therapeutic oral health care. The diversity of surgical and complexity habilitating individuals with facial clefts often necessitates that the dentist work with a team of experts. The use of different services and interventions and their timing are critical to achieve optimal health outcomes in cleft patients. Management of patients from birth to adulthood will be presented and discussed with the main goal to provide the best care and improve the quality of their lives.

Management of Patients with Orofacial Clefts

Velopharyngeal incompetence is a contributing factor to speech disorders and implies the presence of hypernasality, inappropriate nasal escape, and decreased air pressure during speech. One prosthetic treatment is a rehabilitative procedure employing a palatal lift prosthesis (PLP), which reduces hypernasality by approximating the incompetent soft palate to the posterior pharyngeal wall and consists of two parts, the anterior denture base and the palatal lifting plate, which are connected with steel wires; however, it seems difficult to reproduce the mobility of the soft palate in speaking, and it is therefore likely that the palatal lifting plate stimulates or oppresses the tissue of the soft palate and hinders rather than assists articulatory function. To avoid these disturbances we devised an adjustable PLP with a flexible conjunction between the denture base and the palatal lifting plate to obtain the optimal vertical lifting angle. The palatal plate was adapted to conform in a passive manner to the soft palate with light-cured resin. The designed PLP simplified the procedure and reduced the number of adjustments and visits.

A Simplified Palatal Lift Prosthesis for Neurogenic Velopharyngeal Incompetence

Cleft lip and palate (CLP), a congenital disturbance needs a lot of attention with respect to its rehabilitation as a person suffering from this defect can lead a normal life given with the right type of treatment at the right time. However, if a patient cannot get surgical treatment at the appropriate time either due to availability or economic constraints, it is still possible to improve their social and psychological well-being with prosthodontic rehabilitation. The literature search was carried out through PubMed and Google scholar and manual search. The articles related to prosthodontic treatment in congestion with speech therapy and some articles on psychological assessment were considered The available prosthodontic treatment options for improvement of speech is discussed and highlighted the importance of prosthetic management of such patients along with a speech therapist. Also, a review of the available prosthetic treatment options is discussed in detail. Finally, a case report of a CLP patient treated prosthodontically with the assistance of speech pathologist is presented.

Prosthodontic Management in Conjunction with Speech Therapy in Cleft Lip and Palate: A Review and Case Report.

PURPOSE The aim of this study was to assess the effect of a palatal lift prosthesis (PLP) on the speech intelligibility of cleft palate patients treated with pharyngeal flap surgery, the minimum duration required for improvement in nasality, and the sustenance of speech improvement after removing the appliance. MATERIALS AND METHODS Seven patients ranging between 16 and 26 years of age were recruited for this study. These subjects had velopharyngeal dysfunction secondary to a surgically corrected cleft palate, which failed to improve following pharyngeal flap surgery. A PLP was given to these patients and improvements in speech intelligibility were assessed using two speech examinations: perceptual analysis and nasometry. The nasal resonance, nasal air emission, and articulation were measured prior to the insertion of the prosthesis and at the end of every month for the next 3 months, following which the prosthesis was removed and the tests were repeated. RESULTS There was a statistically significant decrease in nasalance percentage at the end of the 3 months, and it was found that this improvement in speech persisted even after the removal of the prosthesis. CONCLUSIONS A PLP, when used for a minimum duration of 3 months, causes a significant decrease in nasal resonance, thereby improving speech intelligibility in patients who failed to see improvement following pharyngeal flap surgery for velopharyngeal incompetence.
