A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth). They are similar to dental retainers, but without the front wire. Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause during feeding. Following surgery, there may remain a residual orinasal opening on the palate, alveolar ridge, or vestibule of the larynx. A palatal obturator may be used to compensate for hypernasality and to aid in speech therapy targeting correction of compensatory articulation caused by the cleft palate. In simpler terms, a palatal obturator covers any fistulas (or "holes") in the roof of the mouth that lead to the nasal cavity, providing the wearer with

- A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth). They are similar to dental retainers, but without the front wire. Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause during feeding. Following surgery, there may remain a residual orinasal opening on the palate, alveolar ridge, or vestibule of the larynx. A palatal obturator may be used to compensate for hypernasality and to aid in speech therapy targeting correction of compensatory articulation caused by the cleft palate. In simpler terms, a palatal obturator covers any fistulas (or "holes") in the roof of the mouth that lead to the nasal cavity, providing the wearer with a plastic/acrylic, removable roof of the mouth, which aids in speech, eating, and proper air flow. Palatal obturators are not to be confused with palatal lifts or other prosthetic devices. A palatal obturator may be used in cases of a deficiency in tissue, when a remaining opening in the palate occurs. In some cases it may be downsized gradually so that tissue can strengthen over time and compensate for the decreasing size of the obturator. The palatal lift however, is used when there is not enough palatal movement. It raises the palate and reduces the range of movement necessary to provide adequate closure to separate the nasal cavity from the oral cavity. and palatal lifts aid in and do not obturate a fistula. A speech bulb, yet another type of prosthetic device often confused with a palatal obturator, contains a pharyngeal section, which goes behind the soft palate. Palatal obturators are needed by individuals with cleft palate, those who have had tumors removed or have had traumatic injuries to their palate. (en)
