Webinar | Differential Diagnosis of Tongue Thrust

Tongue thrust remains debated despite decades of clinical observation and evolving research. Rather than treating tongue thrust as a singular diagnostic entity, this course presents a structured differential diagnostic framework for distinguishing structural, neuromotor, and learned/adaptive contributors to anterior tongue posture and swallowing patterns in pediatric populations. Participants will examine the developmental transition from physiologic infant suckling patterns to increasingly differentiated oral motor control and consider when persistent anterior lingual pressure warrants further evaluation. Emphasis will be placed on distinguishing an observable tongue pattern from its underlying mechanism and considering developmental capacity, craniofacial and dental structure, airway status, feeding and swallowing physiology, and speech motor function. Historical and contemporary literature will be integrated with clinical application to examine potential contributors including craniofacial growth patterns, dental relationships, palatal morphology, tethered oral tissues, airway obstruction, oral habits, dysarthria, motor coordination deficits, and learned compensatory patterns. Case-based examples will demonstrate how airway screening, oral resting posture, swallow analysis, structural assessment, and motor-based speech assessment can be integrated into a cohesive differential diagnostic process. The goal is to move beyond polarized views of tongue thrust and toward evidence-informed clinical reasoning, appropriate intervention, and interdisciplinary referral.
