Question 2. Describe the congenital anomalies of the faciomaxillary region and describe the management of cleft palate
Answer:

Congenital Anomalies:

  • Classification
  • Congenital
  • Harelip- causes
    • Nonfusion of maxillary processes and medial nasal process
    • Defective development of the frontonasal process
    • Non fusion of two mandibular process
  • Oblique facial cleft
    • Arise due to confusion of the maxillary and lateral nasal process
  • Macrostomia
    • Due to inadequate fusion of maxillary and Mandibular process
  • Microstomia
    • Due to too much fusion
  • Bifid nose
    • Due to bifurcation of frontonasal process
  • Mandibulofacial dysostosis
  • Retrognathia or agnathia
  • Hypertelorism- widely separated eyes

Management Of Cleft Palate:

  • Langenbeck’s operation
    • Margins of the cleft are pared, the nasal septum is defined and separated off the upper surface of the cleft palate
    • Mucoperiosteal flaps are lifted from the hard palate
    • Two release incisions are made on each side just medial to the alveolar margins
    • Mucoperiosteal flaps are mobilized
    • The cleft is then repaired

Question 3. Describe the etiology, pathogenesis, clinical features, and management of cleft lip.
Answer:

Cleft Lip

A cleft lip is a congenital anomaly caused due to abnormal facial development during gestation

Cleft Lip Etiology:

  • Hereditary
  • Increased parental age
  • Associated with other syndromes like Pierre Robin’s syndrome, ectodermal dysplasia
  • Environmental factors
    • Nutritional deficiency
    • Radiation exposure

    • Hypoxia
    • Aspirin and other teratogenic drugs

Cleft Lip Pathogenesis:

  • Various Theories Are Put forward, they are
    • Asynchronous development of various processes leading to fusion between them
    • Failure of mesodermal development to form connective tissue bands across lines of fusion
    • Interruption in the migration of the neural crest cells from the neural plate

Cleft Lip Clinical Features:

  • Upper lip cleft is occasionally associated with the presence of two small blind tubes in the lower lip
  • Lower lip cleft is rare
  • Patient looks ugly
  • Difficulty in suckling
  • Teeth may come out through the gap
  • Defective speech
  • Deformed nostrils

Cleft Lip Management:

  • Mirault- Blair operation- it is carried out in three stages
  • Stage 1
    • Adequate mobilization of the lip lateral to the cleft, the ala of the affected nostril, and a considerable part of the cheek is performed the lip is everted
    • The incision is made in a groove between the lip and the maxilla
    • Bleeding is checked by firm pressure
  • Stage 2
    • An ink mark is made on the lip
    • The margins are made of raw
  • Stage 3
    • Skin flaps are sutured
    • A rubber tube is introduced through the nostril
    • The mucous membrane and the muscles are sutured separately with chromic catgut
    • Finally, the skin is sutured

Cleft lip and palate short notes questions

Question 3. Development of face

Answer:

Development Of Face

  • Around 4th week of intrauterine life, a prominent bulge develops on the ventral aspect of the embryo.
  • Below it, there is a depression called stomadeum.
  • The mesoderm covering the developing forebrain proliferates and forms a downward projection called the frontonasal process.
  • The pharyngeal arches are laid down.
  • The first branchial arch helps in the development of nasomaxillary complex.
  • It forms the lateral border of the stomodeum.
  • It gives off a bud from its dorsal end called nasal placodes.
  • These placodes soon shrink to form nasal pits.
    • At this stage, the stomodeum is surrounded
    • Above- frontonasal process
    • Sides- maxillary process
  • Below- Mandibular process
  • The resultant nasal pit divides into the medial nasal process and lateral nasal process
  • The maxillary process lust with the lateral nasal process and forms a nasolacrimal duet
  • Lower Lip
    • The Mandibular processes of the two sides grow towards each other and fuse in the midline to form lower lip ami lower jaw
  • Upper Lip
    • Formed by the two media nasal prominence and the two maxillary prominences
  • Nose
    • The maxillary process fuses with the medial nasal process, as a result, nasal pits are cut off from the stadium
    • The frontonasal process becomes narrower to form nasal septum
  • Cheeks
    • Formed by the fusion of maxillary and Mandibular process

Question 4. Hare Lip
Answer:

Hare Lip It is used to describe defects of the lip

Hare Lip Causes:

  • Nonfusion of maxillary processes with the medial nasal process- leads to a defect in the upper lip
  • Defective development of frontonasal process- leads to midline defect of the upper lip
  • Nonfusion of two mandibular processes- leads to midline defect of the lower lip

Cleft Lip And Cleft Palate Viva Voce

  1. A cleft lip is formed due to disturbance during 6 weeks of IU life
