Epidemiology
• The estimated incidence of CLP ranges from 1:500 live births to 1: 2000 live
births, the incidence is highest in Asians (1:500), the lowest incidence is in
African-Americans (1:2000), but this racial variation is not observed in cases
of isolated cleft palate (CP) with reported incidence of 1:2000 live births.
• Males are predominant in CLP population, whereas isolated CP occurs more
commonly in females.
• Unilateral clefts are 9 times more common than bilateral clefts and they are
more frequent on the left side than on the right.
Etiology
• Clefts can occur as part of a syndrome or as isolated clefts
• Multiple genes have been implicated in the etiology of clefting, in
addition to disturbances in growth factors or their receptors.
• the environmental factors during pregnancy that have been
established in the etiology of CLP include; smoking, alcohol,
anticonvulsants, steroids, folic acid deficiency, hypoxia, retinoids,
radiation, viral infections
Classification
• Many classification systems were proposed for CLP starting in
1920s. Clefts need to be described rather than categorized and the
description of CLP phenotypes should include:
• 1. The laterality (unilateral/bilateral/median) and severity
(complete/ incomplete) of the labial defect.
• 2. Acknowledgment of an alveolar defect.
• 3. Morphological characterization of the palatal defect;
Prenatal diagnosis
• Recent advances in ultrasound imaging have revolutionized
prenatal diagnosis of facial clefts, ultrasound images of
clefts of the lip can be visualized as early as 12-16 weeks
(67%-93% detection rate), whereas diagnostic images of
the palate are more difficult to acquire (7%-22% detection
rate).
Clinical Manifestation
• In unilateral CL there is rotation and distortion of the vermillion
with loss of Cupid's bow and philtral landmarks on the cleft side
• In bilateral CL, the premaxilla grows independently of the
maxillae on either side and may protrude considerably,
particularly in complete clefts. The prolabium, consisting of soft
tissues of the premaxilla without muscle fibers, also lacks
Cupid's bow and philtral columns bilaterally.
Clinical Manifestation
• The spectrum of CP ranges from a submucous cleft to
complete clefting of the primary and secondary palate.
CP is primarily characterized by disorientation of palatal
muscles which lead to feeding difficulties, velopharyngeal
insufficiency, and speech problems.
Submucous Cleft palate
The Spectrum of cleft Palate
Specific goals of treatment
• Normalized esthetic appearance of the lip and nose
• Intact primary and secondary palate
• Normal speech, language, and hearing
• Nasal airway patency
• Class I occlusion with normal masticatory function
• Good dental and periodontal health
• Normal psychosocial development
The management of CLP patients can
be divided into:
1. Preoperative management.
2. Primary operative management.
3. Secondary operative management.
Preoperative management Feeding
• One of the major concerns during this phase of management is feeding, this
concern is not very critical in children born with isolated CL, as they can
feed quite well and even have the opportunity to breastfeed in most
instances.
• Infants with cleft palate, on the other hand, can have difficulty in feeding due
to the inability to form an adequate seal between the tongue and palate for
creation of sufficient negative pressure to suck fluid from a bottle.
Specialized nipples and bottles are necessary to improve feeding.

Pre-surgical orthopedics (PSO)
• PSO entails using devices to mold the perioral structures of the
infant with a CLP to reposition the nasolabial and maxillary
segments closer to each other. It is mainly used in the first few
weeks after birth and in the months prior to palate repair.
• In the authors’ opinions, these techniques often have greater
impact in cases of wide bilateral cleft lip and palate where
manipulation of the premaxillary segment may make primary
repair technically easier.

Treatment planning and timing
• The timing of CLP repair is controversial. The decision to surgically
manipulate the tissues of the growing child should take into account
the possible growth restriction that can occur with early surgery.
• Historically the anesthetic risk-related data suggested that the safest
time period for surgery in this population of infants could be
outlined simply by using the "rule of lO's." This referred to the idea
of delaying lip repair until the child was at least 10 weeks old, 10
pounds in weight, and with a minimum hemoglobin value of 10 g/dl.
Procedure Timing
CL repair After 10 weeks
CLP repair 9-18 months
Pharyngeal flap or Pharyngoplasty 3-5 years or later based on speech
development
Maxillary / alveolar reconstruction
with bone graft
6-9 years based on dental development
Cleft orthognathic surgery 14-16 years in girls, 16-18 years in boys
Cleft rhinoplasty After age 5 years but preferably at
skeletal maturity: after orthognathic
surgery when possible
Cleft lip revision Anytime once initial remodeling and
scar maturation is complete but best
performed after age 5 years

Surgical procedures for Cleft Palate
• CP repair requires the mobilization of multilayered flaps to
reconstruct the defect in a layered fashion by first closing the nasal
mucosa and then the oral mucosa, the surgeon must also
reconstruct the musculature of the velopharyngeal mechanism.
• Therefore, the soft palate is closed in three layers by approximating
the nasal mucosa, velar musculature, and the oral mucosa. The hard
palate portion is closed in two layers using nasal mucosa flaps and
then oral mucosa flaps
Separate the oral mucosa
from nasal mucosa

Complications
• Immediate postoperative complications include
breakdown of the repair due to tension, palatal ischemia,
secondary pressure, secondary trauma, or bleeding.
• Other long-term complications include midface growth
deficiency, velopharyngeal incompetence, recurrent
fistula, and sleep apnea.
velopharyngeal incompetence
Alveolar bone grafting
Goals of alveolar bone reconstruction:
• To provide bone support and adequate attached gingival width for
teeth adjacent to the cleft.
• To close the remaining oronasal fistula.
• To improve support of the nasal alar base and lip on the affected
side(s).
• To allow normal eruption of the permanent teeth in the cleft area and
providing sufficient bone for the placement of dental implants, where
needed.
Alveolar bone grafting
Goals of alveolar bone reconstruction:
• To create an appropriate ridge form to allow for optimization of
orthodontic care and dental alignment.
• To allow for stabilization of the premaxillary segment and to
provide continuity of the maxilla as a whole.
• To improve nasal symmetry.
• To provide support for the upper lip. Timing of the alveolar bone
reconstruction was one of the most controversial issues.
Primary (early) grafting
• which was defined as that performed simultaneously with
lip repair or as grafting performed before the palate is
repaired at age younger than 2 years. This "early''-phase
bone grafting has been associated with reports of
moderate to severe long-term maxillary growth
restriction.
Secondary (delayed) grafting; which can also
be divided into:
• Early secondary; before the eruption of the permanent incisor teeth (3-6
years). The literature does not support early secondary grafting.
• Secondary (mixed dentition); before the eruption of the maxillary canine,
(6-12 years), it can also be divided into early secondary (6-8 years) and late
secondary (8-12 years). Ideally the patient is between the ages of 8 and 12 years
with a maxillary canine root that is one half to two thirds developed, some
authors advocated the early secondary grafting (6-8 years) to preserve the
lateral incisor especially if present in the posterior segment.
Late grafting
• after 12 or 13 years of age, after the eruption of
the permanent canine
Common presenting problems
• Discharge and smell from the nose.
• Oral food/fluids leaking from the nose.
• Poor speech.
• Inability to suck up a straw or blow up balloons.
• Poor appearance of the incisor teeth.
• Missing or supernumerary teeth within the cleft area.
• Difficulty cleaning teeth in the cleft area.
• Poor facial appearance.
Alveolar bone grafting
pre-operative orthodontic treatment
• Orthodontic treatment may be
required to align the maxillary
arch in preparation for the
bone graft. This usually
involves expansion of the arch
in a transverse diameter and
results in opening up the
alveolar cleft to some degree

Postoperative care
• Antibiotics usually start before the incision and continue
postoperatively for 7-10 days along with chlorhexidine
mouth wash, excellent oral hygiene and good nutrition
are encouraged, patients and parents are instructed to
liquid and soft diet for 2-3 weeks and to avoid any trauma
to the operative site.
Complications
• Wound dehiscence which is managed by debridement and
antimicrobial mouth washes with or without systemic
antibiotics.
• Infection which is managed by conservative debridement,
daily irrigation and packing with oral antibiotics.
• Persistent fistula which may require subsequent procedures.
