Oromandibular Limb Hypoplasia | Symptoms & Causes
What are the symptoms of oromandibular limb hypoplasia?
The most common sign of oromandibular limb hypoplasia is an underdeveloped tongue (microglossia) and jawbones, which result in a receding chin. Oromandibular limb hypoplasia can make it hard for a child to open their mouth, breath, speak, or eat, and often causes drooling. A child with oromandibular limb hypoplasia may also have fused fingers or toes.
What causes oromandibular limb hypoplasia?
Oromandibular limb hypoplasia is extremely rare, and we don’t yet know what causes it. Research is underway to investigate how factors during pregnancy, such as using certain antidepressants or anxiety medications, may play a role.
Oromandibular Limb Hypoplasia | Diagnosis & Treatments
How is oromandibular limb hypoplasia diagnosed?
Your child’s doctor may diagnose oromandibular limb hypoplasia based on:
- a detailed review of your child’s medical history
- an extensive physical exam, including a detailed look at your child’s face and mouth
- specialized tests, such as an EKG or hearing tests
