22. AETIOLOGY
Ancient Folk explanations
• Aztecs – eclipses occurred because a bite had been taken
out of the moon
• Prevented with an obsidian knife above the pregnant
abdomen
• Modern Mexico prevented with keys and safety pins
22
23. Early Chinese
• Eating rabbit “hare lip”
• Bad karma or wrong doings
Philippines
• Force to the fetal face
Familial or “In the blood”
23
25. 1] Genetic
• Genetic disorders are classified into 4 groups
1. Chromosomal
2. Single gene
3. Multifactorial – oral clefts
4. Mitochondrial

John B. Thornton, Sue Nim Paul S. Howard. The incidence, classification, etiology and embryology of oral clefts. Semin Orthod 1996;2:162-168
26. 2] Multifactorial because:
1) Chances increases if more than one family member if affected
2) More the severity, greater the chances of recurrence in sibling
3) Higher risk if affected individual is of less affected sex
4) Risk decreases in remotely related individuals
5) Consanguinity increases the rate because of sharing of genes

Complete history of gestation and maternal health, counseling of the parents
Genetisist and other Social workers
67
68. • Second stage – at birth
Pediatrician discusses the condition with the parents,
Surgeon advises about the operative plan,
Dental specialists appraises the arch relationships
• Third stage – birth to 1 year
Pediatrican - advises about the feeding
Surgeon - carries out the lip closure (rule of 10)
Dental specialist - secures the models and radiographs
Speech therapist - discusses about the insufficiency and incompetence of the
pharyngeal seal
68
69. • Fourth stage – 1-2yrs
Pediatrican - takes care of the health and nutrition.
Surgeon carries out the closure of the hard palate 1:2 soft palate 1:6
Speech therapist - monitors the vocabulary and option of a prosthetic
replacement
ENT - monitors the ear condition.
• Fifth stage – 2-6 years

NASOALVEOLAR MOULDING
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
77. • Grayson (1993) – first technique to correct the alveolus, lip and
nose in cleft infants
• Matsuo (1988)
- Research for cartilage moulding
- high maternal level of estrogen at the time of birth correlates with an
increase in hyaluronic acid, which inhibits the linking of the cartilage
intercellular matrix
77
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
78. • Matsuo used a stent, silicone tubes to shape the nostrils
• Grayson (1999) adapted his nasal stent to extend from the anterior
flange of an intraoral molding plate.
• This new technique was named – “ Nasoalveolar molding”
78
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
79. Objectives:
• Reduce severity of initial cleft deformity
• Columella – Nonsurgical lengthening (in bilateral clefts) and uprighting (in
unilateral clefts)
• Reduction in the width of the alveolar cleft segments until passive contact
of the gingival tissues is achieved.
79
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
80. 80
Procedure:
• A heavy-bodied impression material is used to take the initial
impression as soon after birth as possible.
• Grayson and Maull (1999) held infant in upside down position to
keep the tongue forward which permitted fluids to draw off the oral
cavity when impression tray is placed
• Yang (2003) took the impression using a pre-trimmed customized
pediatric tray with the baby being held in the erect position,
by one of the parents
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
81. • Prashanth (2013), Mishra (2010) obtained impression when the infant
was awake in a prone position on the dental chair, the child is held
on the lap of their parents with no anesthesia.
• Dubey (2011) made impression of the cleft region upper arch using
ice cream stick and impression compound.
81
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
82. • Plate – clear self-cure acrylic, trimmed with a denture soft material
• 2–3 mm in thickness
• The retention arm – 40 degrees to get appropriate activation and to
avoid dislodgement of the NAM plate from palate
82
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
83. • The nasal stent is added to the intraoral molding plate when the
cleft alveolar gap is reduced to 5mm or less
• Stent – 0.036-in gauge round stainless steel wire
• The intranasal portion is formed from hard acrylic, covered with a
thin layer of soft spongy acrylic denture liner
83
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
84. • Elastics used are 0.25 inch and it should be stretched about two
times the diameter for activation force of about 2 Oz
84
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
86. 86
Complications and disadvantages:
• Irritation of the oral mucosal or gingival tissue
• Ulceration of intraoral tissues
• The intranasal lining of the nasal tip can become inflamed
• Skin irritation due to tape usage
• Parent compliance required
• Moulding plate may get dislodged and obstruct the airway
*Samuel Berkowitz. Celft Lip and Palate. 2006. 2nd edition Page number 451-8.
87. 87
Benefits:
• Short-term: the tissues are well aligned prior to primary lip and nose
repair
• Long-term:
• change in nasal shape is stable
• Reduced number of surgical revisions
• Reduction of treatment cost
• Shetty V et al (2017) - improves arch symmetry and stability, and thus
may prevent arch collapse in the long term

CHANGING SURGICAL CONCEPT FROM 1920S TO
1950S
• Graber (1950s) – surgery performed early, caused severe midfacial
deformity later
• Brophy, first proponent of surgical technique – steel-clamp and
silver-wire bony closure technique
• von Langenback soft tissue procedure alone to approximate lateral
halves of maxilla and reduce intermaxillary width
*Berkowitz S. A Comparison of Treatment Results in Complete Bilateral Cleft Lip and Palate Using a Conservative Approach Versus Millard-Latham PSOT Procedure. Semin Orthod 1996;2:169-184
96. • Graber, Slaughter and Brodie (1950s-1960s) – negative reports on
surgical procedure done at an early age
• “No palatal surgery at an early age” (before 12 months)
• James Scott (1956) – Sutural growth theory
• McNeil and Burston – adopted his theory – functional paediatric
prosthesis – palatal closure between 5 to 9 years of age
96
*Berkowitz S. A Comparison of Treatment Results in Complete Bilateral Cleft Lip and Palate Using a Conservative Approach Versus Millard-Latham PSOT Procedure. Semin Orthod 1996;2:169-184
97. • Melvin Moss (1968) – functional matric theory – septal cartilage
grows as a secondary response
• McNeil – Father of presurgical orthopaedics – supported Scott’s
theory
• Burston – premaxilla was normal and lateral palatal segments were
retruded in face
• Presurgical orthopaedics + primary bone grafting within first year of
life
• Prusanky – opposed the same

98. CLAIMED BENEFITS OF PSOT
• Control and modify postnatal development of maxilla
• Early alignment for better occlusion and function – swallowing and
speech
• Reduce middle ear infections

*Berkowitz S. A Comparison of Treatment Results in Complete Bilateral Cleft Lip and Palate Using a Conservative Approach Versus Millard-Latham PSOT Procedure. Semin Orthod 1996;2:169-184
99. • Berkowitz (1978) – “State of art”
• Primary bone grafting – deleterious effects on midface
• No evidence that PSOT normalize feeding, tongue posture,
swallowing or growth

100. CONSERVATIVE TREATMENT – THE BEST APPROACH
• Same surgery performed can cause in different results at different
ages:
1. The cleft defect
2. The facial growth pattern
3. The surgical procedure

CLEFT PALATE SURGERY TIMING AND SPEECH
OUTCOME
1970s
• Mid to late 1970’s – 18 to 24 months surgical palate repair
• General trend of better speech results with earlier ages at surgery
• Jolleys (1954) – approximately 90% of children who underwent
surgery before the age of 2 years had good or excellent speech
• General age range for surgery – 6-9 months, before 8 months, 1
year range, between 2 to 3 years
*Peterson S. The Relationship Between Timing of Cleft Palate Surgery and Speech Outcome: What Have We Learned, and Where Do We Stand in the 1990s? Semin Orthod 1996;2:185-191
102. 1980 – 1990s
• Kaplan (1981) – palatal closure between age of 3 to 6 months
• Dorf and Curtin (1982,1990) – importance for phonemic
development or articulation age
• Greater discrepancy in speech performance between the "12
months and younger group" and the children operated on over the
age of 12 months
• Ross (1987) – slightly better facial growth if surgery done in the first
year of life

BONE GRAFTING FOR ALVEOLAR CLEFT
DEFECTS
BONE
GRAFTING
Primary
bone
grafting
First 2 years of
life
Secondary
bone
grafting
Early – 2 to 5
years of life
Late – 11 to 14
years of life
*Waite P, Waite D. Bone Grafting for the Alveolar Cleft Defect. Semin Orthod 1996;2:192-196
105. OBJEVTIVES FOR SURGICAL GRAFTING:
• Stabilization of segments
• Improved oral hygiene
• Nasal secretions prevented from draining into the mouth
• Unites maxilla to better withstand occlusal forces
• Bony base for teeth eruption
• Improves nasal symmetry
• Provide feeling of normalcy and improve social acceptance
105
*Waite P, Waite D. Bone Grafting for the Alveolar Cleft Defect. Semin Orthod 1996;2:192-196
106. BONE GRAFTING AND ORTHODONTIC TOOTH MOVEMENT
• A general rule – “orthodontic tooth movement performed with
improved outcomes after the bone graft has been completed”
• Tooth movement initiated 1 to 3 months after grafting into the grafted
area
106
*Waite P, Waite D. Bone Grafting for the Alveolar Cleft Defect. Semin Orthod 1996;2:192-196
107. SURGICAL MANAGEMNT OF ALVEOLAR CLEFT
• Ideal timing:
- 9 to 11 years of age
- Before canine eruption, canine root is 1/3rd formed (Bergland et al)
• Best source of bone graft: (autologous cancellous bone)
- Anterior portion of iliac crest
- The rib, tibia
- The cranium
- The mandible

110. A] NEONATAL MAXILLARY ORTHOPAEDICS
• McNeil (1950)s – Father of presurgical orthopaedics
• Rationale – realignment of collapsed segments
• Active or passive orthopaedic appliances
110
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204.
111. B] ORTHODONTIC-ORTHOPAEDIC TREATMENT IN DECIDUOUS
DENTITION
• Problems in deciduous dentition:
- Delay in eruption in vicinity of cleft
- Malformed or congenitally missing lateral incisor
- Anterior or posterior buccal crossbite
- Functional shift
111
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204
112. • Turvey (1982) believe that orthodontic treatment in the deciduous
dentition, although possible, is contraindicated
• Rygh and Tindlund (1988) – Growth modification at this stage has
been proposed
• They recommend utilization of a quad-helix appliance soldered to
bands on the primary second molar teeth and canines to expand the
upper arch
• Alongwith protraction face mask to modify and redirect growth
112
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204.
113. C] ORTHODONTIC TREATMENT DURING THE MIXED DENTITION
• Bone grafting:
• 5 to 6 years of age
• After 8 to 9 years of age
• Radiographically, after root of unerupted canine is half or one-third developed.
113
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204
114. • Orthodontics – 6 months before grafting
• Fixed appliance in upper arch
• Objectives at this stage:
- Expansion of maxilla,
- elimination of crossbites, derotations of malposed teeth,
- improve dental and aesthetic function
• Spontaneous canine eruption (27%), surgical uncovering (17%),
combined surgical and orthodontic traction (56%)
• Orthodontics resumed 3 months after graft placement
114
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204.
116. Protraction Facemask Therapy:
• Can be used before bone grafting in mild midfacial deficiency
• Increased growth at circumaxillary sutures
• Orthopaedic force – 350 to 500 gram/side
• 10-12 hours a day
• 12-15 months
116
117. D] ORTHODONTIC TREATMENT DURING THE PERMANENT
DENTITION
• Decision – orthodontics alone OR orthodontic combined with
orthognathic surgery
• Ross (1987) – 25% require surgery
• 3 consecutive cephalogram, 6 months apart showing no change in
length of mandible can be used
117
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204.
118. TREATMENT BY ORTHODONTICS ALONE
1. Tooth alignment
2. Establishment of a continuous maxillary arch with favourable archform
3. Correction of anterior and/or posterior crossbites
4. Stability of occlusion in the presence of dental compensations
5. Favourable dentofacial esthetics
118
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204.
119. TREATMENT BY ORTHODONTICS COMBINED WITH
ORTHOGNATHIC SURGERY
• Severe skeletal discrepancy, oronasal fistulas, speech deformity
• Maxillary surgery – multiple segment Le Fort I osteotomy with down-
grafting
• Presurgical orthodontic treatment – 12 months
• AP discrepancy – more than 8mm – bijaw surgery needs to be
planned
119
*Vlachos C. Orthodontic Treatment for the Cleft Palate Patient. Semin Orthod 1996;2:197-204.
120. • Unilateral clefts – 2 piece Le Fort I osteotomy

*Posnick J. Orthognathic Surgery for the Cleft Lip and Palate Patient. Semin Orthod 1996;2:205-14
121. • Bilateral clefts – 3 piece Le Fort I osteotomy
121
*Posnick J. Orthognathic Surgery for the Cleft Lip and Palate Patient. Semin Orthod 1996;2:205-14
122. • Post-surgical orthodontic – 4 to 6 months
• Transverse maxillary stabilization by transpalatal arch or piggy-back
overlay arches
• Immediate retainers – Hawley’s type
• Cemented lingual arch in maxilla
• Vaccum formed retainers not indicated
122

required for proper diagnosis and treatment planning of such patients
• Treatment begins soon after birth and continues till adulthood
requiring a team approach.
129
130. CONCLUSION
• Multiple problems and syndromes with clefts
• Multidisciplinary approach for management, patient-centered
• Variations in treatment sequence
• Role of orthodontists
