Palatal lift prothesis

Jump to navigation Jump to search A palatal lift prosthesis is a prosthesis that addresses a condition referred to as palatopharyngeal incompetence. An inability to adequately close the palatopharyngeal port during speech results in hypernasalance that, depending upon its severity, can render speakers difficult to understand or unintelligible.

It may be used to aid in improving articulation and feeding. The blockage of the opening helps improve hypernasality and suckling ability for babies. In the case of a labial-oral-nasal fistulathe plate may include an anterior upward extension to fully occlude the passageway running between the labial surface of the alveolusalveolus, and nasal cavity.

The plate may be constructed to include any congenitally missing teeth to improve articulation and appearance.

Individuals who use palatal plates must be monitored periodically by their dental professionals due to possible tissue irritation by the plate. Materials such as food particles, oral mucosa and secretions may cause buildup on the upper surface of the plate; therefore, it is essential to clean a palatal obturator at least twice a day to avoid tissue irritation.

There are also more specific terms used for obturators depending on their time and purpose of use: A modification obturator may be used in the short term to block a palatal fistula, for augmentation of the seal and to separate the oral and nasal cavities.

An interim palatal obturator is used post-palatal surgery. This obturator aids in closing the remaining fistula and is used when no further surgical procedures are planned.

It must be frequently revised. A definitive obturator is used when further rehabilitation is not possible for the patient and is intended for long-term use. Palatal adhesives are oral adhesives or skin barrier materials used to occlude a fistula of the hard palate.

Obturators of this type must be removed before eating and drinking. Users must cut the new piece of adhesive and hold it over the fistula until it adheres.

Adhesives are not to be used for soft palate fistulae if the soft palate has some mobility due to possible unintentional dislodging and digestion of the material. The Nance Obturator[ edit ] This fixed obturator is based on the Nance appliance, which was originally used as a space maintainer in dentistry and orthodontics, but has been redesigned for closing anterior palatal fistulas in patients with cleft lip and palate.

The Nance obturator may be used when the surgical closure of the fistula is not feasible and a removable device is not successful. Speech[ edit ] Often a palatal obturator is used because a palatal fistula can affect development and proper articulation.

Misarticulationsabnormal nasal resonance and nasal escape or air often results from the problem.

Fistulae may decrease intraoral air pressure during production of oral pressure consonants causing distortion of sounds as well as increase in nasal airflow. It is common for an individual with a fistula to compensate for a loss of pressure during speech sound production by attempting to regulate intraoral air pressure with increasing respiration effort and using compensatory articulation.

Middorsum palatal stops atypical place of articulation often results from palatal fistulae causing sound distortions during speech. Occlusion for the fistula is attempted by speakers with deviant tongue placements during these palatal stops.

The palatal obturation may be managed temporarily or may be sustained for longer periods of time. Location-specific palatal obturation has been documented to significantly improve articulation errors, hypernasality based on listener judgmentsand nasal emissions immediately post-obturation only.

Usage of more anterior tongue placements is considered a primary target for speech therapy. The relationship between palatal openings and articulation is important to note prior to surgical plans to ascertain timing of speech therapy and most appropriate therapy goals and approach.

Speech therapy may be most beneficial prior to sustained palatal obturation rather than short-term obturation.at your monthly rounds you are discussing a patient with ALS. you recommended a palatal lift prosthesis but other team members saw no reason for this intervention because of the degenerative nature of the disease.

to make your case you recall that esposito and associates recommended considering a palatal lift prosthesis for individuals with als. what is your rationale?

Nov 29,  · The palatal lift is a device reserved generally for patients in whom there is adequate tissue but poor control of coordination and timing of velopharyngeal movement.8,9 The use of a palatal lift not only acts as a passive support but may also stimulate motions of the velum, and the posterior or lateral pharyngeal wall It may enhance.

September 25, Palatal Lift Prosthesis - Correct Coding. Joint DME MAC Publication. A palatal lift prosthesis is a dental appliance that is used to support the soft palate in individuals lacking the normal muscle function necessary to maintain the soft palate in its normal position.

Statement Of Problem. When surgical treatment is not considered an option, prosthetic management of velopharyngeal insufficiency is carried out by means of a speech-aid prosthesis, whereas velopharyngeal incompetence is traditionally managed by a palatal lift prosthesis.

A palatal lift prosthesis is a prosthesis that addresses a condition referred to as palatopharyngeal incompetence. Palatopharyngeal incompetence broadly refers to a muscular inability to sufficiently close the port between the nasopharynx and oropharynx during speech and/or swallowing.
