Cleft Palate
Cleft Palate is a facial deformity, so rare that most people have
never heard of it, occurring 1 in 800 live births. Some babies are born
only cleft lip and others more demonstrate more severity that includes
the palate.
Treating cleft palate involves more than just a plastic surgeon to
repair the cosmetic aspects. Since cleft palate often involves the ear,
an otolaryngologist (ear, nose, and throat doctor), audiologist, and
speech pathologist are also on the team. Also involved are an
orthodontist, oral and maxillofacial surgeon, general dentist,
prosthodontist, neurosurgeon, pediatrician, psychologist, and a social
worker. This is called the "team approach." These special children
need the coordinated talents of many specialists. Dr. Feldman has been
the team orthodontist for the USF craniofacial/cleft palate team since
1984.
Dr. Feldman explains what happens with cleft palate. "The lip and
palate (the hard bony plate in the roof of the mouth) fail to
differentiate at critical points in the time of the developing child.
Consequently, if differentiation of the tissues that make up these
structures is incomplete or abnormal, the union of the lip and palate
can be lacking in varying degrees. The resulting defects may be
incomplete, in which only the lip and/or palate is partially involved,
or complete, in which both the lip and palate are totally involved. The
cleft can be unilateral (one-sided), or bilateral (occurring on both
sides). Clefts occur more often in boys and normally more on the right
side."
"The whole idea behind early orthodontic/orthopedic intervention is
to move bones back to where they belong," states Dr. Feldman. "Newborns' bones are more pliable and are easy to move. Usually bone
must be moved before any surgery can take place. Therefore, many cleft
palate children are fitted with orthodontic/orthopedic appliances in the
hospital before they are taken home."
Neo-natal maxillary orthopedic appliances are used to appropriately
align the maxillary bones. One of them, a Latham appliance (named
after the Canadian doctor who invented it), is used to align the
premaxilla prior to plastic surgery closure.
In order to fabricate an appliance for neo-natal maxillary
orthopedics, an impression of the child's palate is taken with an
alginate material, which is the same material used in taking dental
impressions. Dr. Feldman then uses this impression to fabricate the
appliance that will be inserted onto the palate, in order to move the
upper segments together.
