PATIENT MATERIALAll records in which a diagnosis of micrognathia

had been recorded in the medicalrecords section of the Johns Hopkins Hospitalbetween 1926 and 1957, and additional casesthrough January 1960 brought to our attentionby members of the pediatric department, werereviewed. At the outset, it should be noted thatin only a minority of the records was there adefinite statement as to whether glossoptosiswas present or not. However, a history of recurrentepisodes of cyanosis, usually relievedby changing the infant from the supine to theprone position, was considered sufficiently typicalof glossoptosis to warrant inclusion in thisseries, when accompanied by presence of theother criteria of the syndrome. Furthermore, itwas found that micrognathia and glossoptosisnot infrequently occurred in association withpalatine anomalies other than the classic cleftpalate (such as a high, arched palate, orpalate ogivale, absent soft palate, or bifiduvula). Thus, our criteria for acceptance of acase in this series consisted of the following:micrognathia; a cleft or abnormal palate;glossoptosis or a history of cyanotic and chokingspells suggestive of glossoptosis. The recordswere reviewed with emphasis on thefollowing aspects.PalateRESULTS OF ANALYSISThe patients are divided into three groupswith regards to the palate.I. Micrognathia with cleft palate, 25cases.II. Micrognathia plus other abnormalityof the palate, 10 cases.III. Micrognathia with history and findingssuggestive of the syndrome but palateinadequately described, 4 cases.TongueGlossoptosis was present in 24 cases, thetongue
