Stickler syndrome
Overview
Board takeaway: Assess the Robin-sequence airway and coordinate cleft care; recognize retinal symptoms as an urgent medical issue.
What causes Stickler syndrome?
Pathogenic variants in collagen genes cause a variable connective-tissue disorder. COL2A1 and COL11A1 are important causes; inheritance is usually autosomal dominant, while some COL9-related forms are autosomal recessive. Ocular involvement and hearing severity differ by type.
Which systemic findings distinguish Stickler syndrome?
Myopia, vitreous abnormalities, cataracts, and retinal detachment risk are central findings in ocular forms. Hearing impairment, joint hypermobility, early degenerative joint disease, and spinal or skeletal abnormalities may occur. Intellectual development is generally typical; hearing or vision limitations can affect communication.
What oral and craniofacial findings occur in Stickler syndrome?
Midface hypoplasia, micrognathia, cleft or submucous cleft palate, bifid uvula, and Robin sequence may occur. Robin sequence combines a small mandible, posterior tongue displacement, and airway obstruction, often with cleft palate. Malocclusion and enamel defects are reported; prior mandibular distraction can affect developing teeth.
How should dental treatment be planned for Stickler syndrome?
Review current airway obstruction, sleep apnea, feeding, cleft repairs, and prior mandibular procedures. Coordinate orthodontic and cleft-team care. Adapt communication for sensory impairment. When anesthesia is needed, micrognathia and glossoptosis may complicate ventilation or intubation. The airway team selects interventions; tracheostomy is not a universal treatment requirement.
What treatment and prognosis apply to Stickler syndrome?
Care includes ophthalmic surveillance and treatment, hearing support, cleft and airway management, and musculoskeletal care. New flashes, floaters, visual-field loss, or sudden vision change require urgent ophthalmic assessment. Cardiac prophylaxis is assessed from an actual qualifying lesion; mitral valve prolapse alone is not sufficient.
