Embryology
6 weeks gestation (human) 13 somite stage
(mouse)
15
Embryology
Sperber Clefting occurs because of failure of
fusion of MNP (medial nasal process) and
maxillary process (MxP)
16
Embryology
Carstens and Walters Clefting occurs because of
failure of Rhombomere r2 to migrate. This better
explains the clinical observation that the most
severe deficiency is in the lateral nasal area
17
Embryology
Proposed migration path of r2 the rhombomere
process migrates towards the free margin of the
lip and gingiva before continuing cephalad
towards the lateral nose
18
Embryology

migration

Furlow double opposing Z-plasty
Z-plasty results in longer palate
24
Treatment
Treatment sequence of complete cleft lip and
palate First, get the segments in alignment by
pre-surgical orthodontics, then perform lip and
gingiva repair. Typically this occurs during the
first months of life (3 months)
25
Palate repair is a separate stage Typically
before the age of one year. The levator muscle
should be ready and mobile (free of scarring) for
the phase of speech acquisition 15-18 months
26
Surgical aims in cleft lip repair
  • Reposition ala
  • Restore nasal floor
  • Lengthen columella on cleft side
  • Lengthen medial lip segment (typically, lateral
    lip segment has enough length)
  • Reconstitute symmetrical vermillion roll
  • Restore dry vermillion medially (typically,
    lateral segment has enough dry vermillion)
  • Align wet vermillion to dry vermillion line (wet
    to dry line
  • Realign and correct abnormal insertion of
    orbicularis oris muscle
  • Reconstitute philtral column (typical by placing
    the scar at the philtral column site)

Techniques of cleft palate repair
  • Von-Langenbeck with Intravelar Veloplasty linear
    scar with muscle alignement (see previous slides)
  • Two-Flap palatoplasty with IVV
  • Furlow double opposing Z-plasty (previous
    slides)

30
Secondary deformities
  • Velopharyngeal incompetence

Velopharyngeal incompetence

VPI pharyngeal flap
33
Dental eruption
  • Lateral incisor absent in 70 cases
  • Canine tooth absent or abnormal in 15 (?) of
    cases
  • Canine tooth can be successfully erupted through
    cleft once the cleft alveolus is bone-grafted
  • Implants-Orthodontics

34
Growth Maxilla and mandible
  • Higher prevalence of class III occlusion
    (maxillary retrognathia) The maxilla is
    underdeveloped, due to surgical and/or congenital
    etiology
  • Growth restriction highly correlated with
    surgical technique scarring, incisions and
    denuded bone.
  • Can be corrected by maxillary advancement (lefort
    I or lefort III)

Craniofacial Malformations
  • Craniosynostosis
  • Craniosynostosis syndromes
  • Mandibulo-Facial Dysostosis
  • Hemifacial Microsomia and Oculo-Auriculo-vertebral
    Syndrome

39
Craniosynostosis
40
Craniosynostosis
  • Sagittal Scaphocephlay (boat)
  • Unicoronal Plagiocephaly (twisted)
  • Bicoronal brachycephaly (short)
  • Metopic trigonocephaly (keel)
  • Most commonsagital
  • Biggest differential deformational
    plagiocephaly or positional plagiocephaly
    non-synostotic

Craniosynostosis syndromes
  • Associated with midface abnormalities Base of
    skull synchondrosis
  • Associated with finger/toe malformation often
    diagnostic
  • Other associated malformations

45
Major Craniosynostosis syndromes
  • Crouzon normal hand
  • Aperts Major syndactyly
  • Pfeifer broad thumbs
  • Muenkes syndrome First genetic-based diagnosis
    FGFr-3 mutation predictably causing bicoronal (or
    unicoronal) synostosis
