On physical examination, he was found to have micrognathia with glossoptosis
, high and large cleft palate.
The Robin sequence typically consists of micrognathia (abnormally small mandible, or lower jaw); glossoptosis
(downward and posterior displacement of the tongue, which appears larger due to the small mandible); and cleft palate.
The term Pierre Robin Sequence is given to a birth defect which involves an abnormally small lower jaw (migrognathia) and a tendency for the tongue to "ball up" and fall backward toward the throat (glossoptosis
 Obesity, enlarge adenoids and tonsils, relative glossoptosis
, excessive secretion adds further challenges from anesthesia point of view.
Children with Down syndrome have a number of other factors contributing to development of SDB including macroglossia, glossoptosis
, hypopharyngeal collapse, tracheal stenosis, laryngomalacia and recurrent enlarged adenoids (27,28).
It is associated with a cleft palate and consists of micrognathia, glossoptosis
, and varying degrees of airway obstruction.
There was associated micrognathia and glossoptosis
. There was high arched palate with cleft palate.
Initially, these conditions were thought to be secondary to glossoptosis
; more recently, it has been determined that the anatomy of the airway plays a major role in determining the risk of airway compromise.
