retrognathia

It is likely going to be less successful for patients with retrognathia.

A small or recessed jaw (retrognathia).

If the infant is not closing down properly, the lower jaws become more noticeably deficient (micrognathia or retrognathia).

Displaced receding chin (retrognathia)

When the reverse is the case, and the lower jaw extends forward beyond the upper, the condition is referred to as retrognathia (reverse overjet).

"Overbite" may also be used commonly to refer to Class II malocclusion or retrognathia, though this usage can be considered incorrect.

Features included hypoplastic lungs, cleft palate, retrognathia, micrognathism, small thorax, diaphragmatic hernia, distal limb hypoplasia, and early onset of polyhydramnios with premature delivery.

The three main features are cleft palate, retrognathia (abnormal positioning of the jaw or maxilla) and glossoptosis (airway obstruction caused by backwards displacement of the tongue base).

Affected children have various characteristic physical features, including clubfoot, "locked" little fingers, microcephaly (small head), hypertelorism (widely spaced eyes), broad, prominent nose bridge, downward-slanted palpebral fissures, small ears, retrognathia, and short neck.

This is usually performed to correct skeletal malocclusions, that is discrepancies in tooth position that cannot be corrected by simple orthodontic movement, and realignment of the temporomandibular joints, or to correct facial deformities such as mandibular retrognathia.

Features distinguishing Weaver syndrome from Sotos syndrome include broad forehead and face, ocular hypertelorism, prominent wide philtrum, micrognathia, deep-set nails, retrognathia with a prominent chin crease, increased prenatal growth, and a carpal bone age that is greatly advanced compared to metacarpal and phalangeal bone age.
