1
Q

Unilateral or Bilateral Cleft Lip

A

Failure of fusion of the maxillary prominence with the medial nasal prominence

2
Q

Oblique Facial Cleft

A

1) Oro-auricular type - lateral part of mouth toward the auricle
2) Oro-orbital type - Mouth toward medial edge or orbit

Both result from failure of fusion between maxillary and lateral nasal prominences

3
Q

Median Cleft Lip (hare lip)

A

Persistence of the groove between the adjacent medial nasal prominences

4
Q

3 causes of cleft palates

A

1) Tongue fails to move inferiorly during the time of palatal process elevation and fusion
2) Cysts can form from the peristence of epithelial reminants formed during fusion
3) Mechanisms that cause impediment of shelf force (force that extends secondary palate shelves)

5
Q

Mandibulofacial dystosis

A

1) Clefts of structures derived from arch 1
2) Downward slanting palpebral fissures
3) Deafness and lower lid coloboma
4) hypoplastic zygomatic and mandible bones

6
Q

Maxillary Hypoplasia

A

Hypoplasia of the midface area with hypertelorism and coronoal suture syntosis

7
Q

Mandibular Hypoplasia

A

1) A small lower jaw
2) Glossoptosis (abnormal downward or back displacement of tongue)
3) cleft palate

8
Q

CHARGE

A

Coloboma, Heart Defects, Atresia, Retardation, Genital hypoplasia, Ear anomalies

9
Q

Holoprosencephaly

A

Defect in bilateralization of the forebrain and a defect in occular development (Cyclopia)

10
Q

Aperts Syndrome

A

Presence of tower shaped skull

11
Q

Accutane Induced Facial Dysplasia

A

First pharyngeal arch defects, ear anomalies, skin problems, cleft lip and palate

12
Q

Lateral Facial Dysplasia

A

1st and 2nd arch syndrome

13
Q

Dacryostenosis

A

Blockage of nasolacrimal duct

14
Q

DiGeorge Syndrome

A

Insufficent Neural crest migration
