2. Sets of soft and skeletal tissue clefts in Facial and Cranial
regions
Can present as hypoplasia or hyperplasia
TESSIER clefts
Orbits and Eyelids represent the interface of cranium and
Facial structures.
Above Orbit ………… Cranial Clefts (8 to 14)
Below Orbit………. Facial Clefts (0 to 7)
3. Abnormal ossifications in or
between the ossification centers
Preventing the adjacent soft tissue to
develop normally
4. 0 TO 14
Often occur in combination
Sum of facial and cranial no. is always 14
Skeletal numbers are more consistent
than soft tissue numbers
5.
6. Median ------------- 0 , 14 , 30
Para median------- 1 - 2 and 12 - 13
Orbital -------------- 3 - 5 and 9 - 11
Lateral --------------- 6 - 7 and 8

8. Midline cleft
Can be divided into
◦Aplasia /hypoplasia
◦Dysraphia
◦Hyperplasia
9. Normal to severe midline agenesis
Mild to severe hypotelorism and CNS anomalies
SOFT TISSUE INVOLVMENT
False median cleft lip
Narrowing to absent of columella
Lack of Nasal tip projection
SKELETAL INVOLVMENT
Hypoplastic Nasal structures
10.
11. Failure of fusion of midline structures
◦ True Median cleft lip
◦ Encephalocele
SOFT TISSUE INVOLVMENT
Failure of fusion of paired medial nasal processes
SKELETAL INVOLVMENT
Midline alveolar clefts
Midline primary palatal clefts
12.
13. Minor duplication of nasal septum TO severe
hypertelorism and nasal duplication
SOFT TISSUE INVOLVMENT
Widened philtrum
Bifid nasal tip/ duplication
SKELETAL INVOLVMENT
Widened maxillary process
Duplicated nasal spine
Frontal bossing
Hypertelorism
