OBJECTIVES :
The development of CLP The etiology of Cleft CLP The normal anatomy of CLP The anatomy of Cleft LP The classification of Cleft LP The key features of the Perioperative care of the child with Cleft lip & Palate The associated complications of Cleft lip & their management
DEVELOPMENT OF FACE :
After 8 weeks Embryo is called ‘Fetus’ due to the fusion of prominences.
Development of face
Appearance of ‘5’ prominences
Growth of these prominences Fusion of the prominences
EMBRYOLOGY OF LIP:
EMBROLOGY
Palatal development
to 10 th 7 th weeks
Palatal shelves
are initially oriented vertically
Head
straightens , allowing the grows & the
tongue neck
falls away
palatal shelves
to rotate upward into normal horizontal position.
Growth factors & hyalronic acid
Frontonasal Forehead, bridge of nose, medial & lateral nasal prominences, nasal septum Maxillary Cheeks, lateral portion of upper lip Medial nasal Philtrum of upper lip, crest & tip of nose Lateral nasal Alae of nose Mandibular Lower lip
THE INCIDENCDE:
The isolated cleft palate is 0.5:1000 Cleft lip with or without palate is 1:1000 CL/P predominates in males Isolated CP predominates in females Majority of bilateral CL(86%) & unilateral CL(68%) are associated with a CP Unilateral CL : Left side affected in 60% Unilateral CL are 9 times common than Bilateral Typical distribution of cleft type is:
Cleft lip alone: 21% Cleft lip & palate: 46% Isolated cleft palate: 33%
ETIOLOGY Idiopathic Genetic defect Environmental Teratogens
Phenytoin , Other Anticonvulsants, steroids
Maternal Smoking , old age marraiges
Alcohol & Retinoic Acid Familial-
1 Affected Child Or Parent, Risk Of Child Of The Next Pregnancy Having CLP Is 4% If 2 Previous Children Have CLP Risk Increase To 9% If 1 Parent & 1 Child Were Previously Affected, Risk Is 17
Not associated with solar or moon eclipse
LIP ANATOMY
, White Skin Roll & Vermillion.
, Symmetrical Alar Arches & Equal Alar Base.
MusclLip – Consists Of Symmetrical Cupids Bow & Philtral Colum – Orbicularis Oris .
Nose – Straight Columella & Septum
CLASSIFICATION
CLEFT LIP
UNILATERAL
BILATERAL
MEDDIAN
○
COMPLETE/ SEVERE

MICROFORM/ MILD
CLEFT ALVEOLUS
1.
NARROW- NON COLLAPSE 2.
NARROW- COLLAPSE 3.
WIDE- NON COLLAPSE 4.
WIDE- COLLAPSE
NASAL DEFORMITY
Mild Lateral Displacement Of The Alar Base, called flaring of ala of nose Normal Alar Contour & Dome Projection Moderate – flaring of Alar Base, Columella Deficiency A Depressed Dome.
Severe Flaring of ala nose deprressed Alar Dome Complete Collapse Of Lower Lateral Cartilage Severe Deficiency Of Columella Height.
Hypoplasia of alar cartilage
MICROFORM CLEFT LIP
Furrow Or Scar .
A Vermilion Notch.
Imperfection In White Roll. Varying Degree Of Vertical Lip Shortness.
Nasal Deformity – May Be Present
UNILATERAL INCOMPLETE CLEFT LIP
Varying Degree Of Vertical Seperation Of Lip An Intact Nasal Sill/ Simonart Band
UNILATERAL COMPLETE CLEFT LIP
Disruption Of The Lip, Nostril Sill & Alveolus(complete Primary Palate) No Simonart Band
INCOMPLETE BILATERAL CLEFT LIP
INCOMPLETE WITH A NEAR NORMAL NOSE.
NORMALLY POSITIONED PREMAXILLA.
SIMONART BANDS & CLEFT INVOLVING ONLY LIP.
COMPLETE BILATERAL CLEFT LIP Protuded Premaxilla Poorly Formed Or Absents Anterior Nasal Spine Severe Nasal Deformity, Flat Nasal Tip The Portion Of LIP between Philtral Columns Form Wide, Short Disk Called Prolabium.
classification of Cleft Palate
EMRYOGENIC Cleft of primary palate Cleft of secondary palate ANATOMIC Ceftt of uvula Cleft of soft palate Cleft of hard palate Cleft of alveolus SIMPLE Anterior and posterior
Classification
Kernehans striped Y Classification Veau Classification 1931 Veau Class I: isolated soft palate cleft Veau Class II: isolated hard and soft palate Veau Class III: unilateral CLAP Veau Class IV: bilateral CLAP
Symptoms
Separation of the lip Separation of the palate (roof of the mouth) Nasal distortion Misaligned teeth Recurring ear infections
Symptoms (cont.)
Failure to gain weight Nasal regurgitation when bottle feeding Poor speech Growth retardation
PROBLEMS (PATHOPHYSIOLOGY)
LIP
Inability to have a tight seal Malocclusion,
alveolar defect & teeth deformities PALATE
Inability to separate nasal from oral Feeding difficulty
Regurgitation Middle ear disease Speech problem
PROBLEMS
Upper airway Speech Feeding difficulty Ear infection
Airway Problems
Cleft Palate patients e.g. Pierre-Robin Sequence Micrognathia , Cleft Palate, Glossoptosis CYANOSIS develop airway distress from tongue fall and touch pharanyx lodged in palatal defect
FEEDING PROBLEM
FEEDING IN HEAD ELEVATED POSITION FEEDING WITH SPCIAL CP BOTTLES OR D/SYRINGE OR DROPPER AFTER FEED LAY BABY ON SHOULDER AND SLAB ON BACK TILL RETCHING
Hearing problem
ETD- Due to abnormal insertion of levator veli palatini and salpingo pharyngeus muscle into hard palate milk enter into eustachian tube and lead to serous otitis media and infective oscicles otitis media and finally ankylosis of 30% develop permanent deafness
Speech Disorders
Errors in Articulation: Fricatives, Affricates Velopharyngeal Competence competence after initial palate surgery Incompetence- nasal emission or snort Evaluation- Direct exam , Fiberoptic Exam
TIMING OF SURGERY
RULE OF TENS FOR CL:
1O POUNDS
10 gm OF Hb 10 WEEKS OF AGE 10,000 TLC
FOR PALATE 10 KG 10 GM Hb 10 MONTH 10000 Tlc
Treatment
Treatment involves many things which include plastic surgery, orthodontics, and speech therapy
PRIMARY MANAGEMENT
Antenatal Diagnosis
Diagnosed By US 3D After 18 Weeks’ Gestation Parents Need Counseling Reassure The Parents Explain Functional Problems Advise On
Feeding
Timing Of Surgery
○
Ideally, The Newborn Infant With A Cleft Is Evaluated By Cleft Team In 1 st Weeks Of Life
PRESURGICAL MANAGEMENT
1:Presurgical infant orthopedics:
Appliances latham appliance for collapsed alveolar arch
2:Presurgical nasoalveolar molding : objective of NAM :
To align & approximate the alveolar segment To correct the malposition of the nasal cartilage & alar base on affected side To idealize the position of philtrum & columella
Naso alveolar mold
Surgical techniques:
For unilateral cleft lip:
Modern accepted technique is the modified Millards rotation & advancement repair
For microform cleft lip:
Straight line repair Modified Millard rotation – advancement repair
For bilateral cleft lip:
1,
Manchester repair 2. bilateral millard repair
MANCHESTER REPAIR
Surgical Repair- Cleft Palate
Several Techniques less scarring and less tension on palate Scarring of palate may cause impaired mid-facial growth(alveolar arch collapse, midface retrusion, malocclusion) Facial growth may be less affected if surgery is delayed until 18 months, but feeding, speech, socialization may suffer.
Surgical techniques
Von langenback operation Veau, Wardill, Kilner push back palatoplasty Intravelar veloplasty Furlow z – plasty Bordeck palatoplasty
Complications of lip repair
Unilateral cleft lip:
Deficient tubercle Vermilion deficiency & irregularity Short upper lip or Long upper lip Tight upper lip Unfavorable scar
Bilateral cleft lip:
Whistle deformity Nostril stenosis
complications
Immediate Bleeding Delayed Fistula formation Failure of repair Speech problem
Bilateral incomplete cleft lip bilateral millard procedure
bilateral millard repair Bilateral complete cleft lip
unilateral Complete cleft lip
Incomplete cleft lip
POSTOPERATIVE CARE
Soft arm restrain for 2 weeks Analgesics Feeding Suture line care Stitch removal Avoid oral suction
POSTOPERATIVE CARE
Fluids for one week Water after every feed Semi solids for next two weeks and water after every diet Solids are allowed after three weeks No need to remove stiches (vicryl)
Cleft palate
Lower lip cleft (cleft 30)
CONFIDENCE LIKE ART NEVER COMES FROM HAVING ALL THE ANWERS, BUT IT COMES FROM BEING OPEN TO ALL QUESTIONS !
