Abstract
A combined obturator and expansion appliance design is described for use in patients with patent oronasal fistulae. This is helpful in cleft palate cases, where small fistulae may increase in size during orthodontic expansion of the upper arch, resulting in increased hypernasality of speech and nasal escape.
