📋 Overview

Fusion of these prominences forms the philtrum, upper lip, nose, jaws and palate. Failure of fusion causes cleft lip and/or palate, with multifactorial inheritance.

🔬 Basic Science

Fusion of these prominences forms the philtrum, upper lip, nose, jaws and palate. Failure of fusion causes cleft lip and/or palate, with multifactorial inheritance.

🏥 Clinical Relevance

Cleft palate occurs from failure of fusion of the palatal shelves (~week 8–10).

🧪 Investigations

Investigation depends on clinical context: relevant blood tests, imaging, and specific genetic or histopathological tests as appropriate. Refer to specialist services where indicated.

💊 Management

Management is condition-specific and typically multidisciplinary, combining medical therapy, surgical intervention where appropriate, supportive care, and family/genetic counselling.

Common SBA themes: recognising the underlying mechanism, identifying classic clinical features, and choosing the first-line investigation or management step. Watch for inheritance pattern and characteristic associations.

  • Cleft lip: failure of maxillary and medial nasal fusion (~week 6).
  • Cleft palate: failure of palatal shelf fusion (~week 8–10).
  • Cleft lip/palate is more common in boys; isolated cleft palate is more common in girls.
  • Pierre Robin sequence: micrognathia, glossoptosis and cleft palate.
  • Maternal smoking and certain anti-epileptic drugs increase orofacial cleft risk.
