Pierre Robin Sequence

Disease Overview

Pierre Robin Sequence (PRS) is a rare congenital condition characterized by a triad of craniofacial anomalies: micrognathia (small lower jaw), glossoptosis (backward displacement of the tongue), and airway obstruction. Often associated with a cleft palate, this condition can cause significant breathing and feeding challenges in newborns and infants.

Disease Category

Craniofacial Developmental Disorder

Synonyms

• Robin sequence
• Pierre Robin syndrome
• Robin anomaly
• Robin complex

Signs & Symptoms

• Micrognathia (undersized lower jaw)
• Glossoptosis (backward tongue displacement)
• Potential cleft palate
• Airway obstruction
• Breathing difficulties
• Feeding challenges
• Increased risk of respiratory complications
• Potential speech and hearing difficulties
• Potential sleep apnea
• Potential dental misalignment

Causes

• Genetic mutations
• Developmental disruptions during embryonic growth
• Potential chromosomal abnormalities
• Associated syndromes:
  • Stickler syndrome
  • 22q11.2 deletion syndrome
  • Treacher Collins syndrome
• Potential environmental factors during fetal development

Affected Populations

• Incidence: 1 in 8,500 to 14,000 live births
• Equal prevalence in males and females
• Occurs across all ethnic populations
• Can be sporadic or inherited

Diagnosis

• Prenatal ultrasound screening
• Physical examination at birth
• Imaging studies:
  • CT scan
  • MRI
• Genetic testing
• Comprehensive craniofacial assessment
• Sleep study to evaluate respiratory function

Standard Therapies

• Immediate Airway Management
  • Prone positioning
  • Nasopharyngeal airway
  • Potential intubation
• Feeding Support
  • Specialized feeding techniques
  • Feeding tubes
  • Specialized bottles
• Surgical Interventions
  • Mandibular distraction osteogenesis
  • Cleft palate repair (typically 9-12 months)
• Multidisciplinary Care
  • Pediatric specialists
  • Craniofacial surgeons
  • Otolaryngologists

  • Orthodontists

Clinical Trials and Studies

• Ongoing research into genetic causes
• Surgical technique improvements
• Long-term developmental outcome studies
• Genetic screening and intervention studies
