Background: Achondroplasia is a genetic condition that results in several orofacial and physical manifestations that predispose patients to dental, breathing, and sleep issues.

Case Description: This report details the case of a 2-year-old girl with achondroplasia, malocclusion, speech and breathing dysfunction, and obstructive sleep apnea (OSA). Treatment involved using a myofunctional device that required chewing twice per day, two simple tongue exercises, speech-language therapy, chiropractic therapy, and continuous positive airway pressure (CPAP) for 24 months. Throughout the treatment period, the patient demonstrated significant improvements in her sleep, breathing, dental occlusion, speech, and overall confidence.

Conclusion: This case report highlights how pediatric patients with achondroplasia can improve their OSA symptoms and health with conservative myofunctional therapy interventions.
