Speech

Treacher Collins syndrome causes a patient to have abnormal intraoral relationships:

• The tongue is disproportionately large in relation to the oral cavity
• The presence of cleft palates
• abnormal movement of the mandible will contribute to speech anomalies.

Auricular and ossicular anomalies that lead to hear loss, acts as a barrier to normal speech and language development.

Most patients with Treacher Collins Syndrome have at least a moderate conductive hearing loss.
