Increased anterior facial height can significantly impact craniofacial relationships, particularly concerning airway dynamics and sleep quality. When there is greater vertical growth of the anterior facial region, it can lead to changes in the position of the mandible and tongue, resulting in a smaller or poorly defined airway space. This configuration can increase the risk of obstructive sleep apnea, where the airway becomes compromised during sleep, leading to repetitive interruptions in breathing.

Understanding the implications of anterior facial height is crucial for diagnosis and treatment planning in orthodontics. As facial height increases, the relationship between oral structures and the airway can be adversely affected, contributing to the likelihood of sleep-disordered breathing. Thus, recognizing the connection between increased anterior facial height and the exacerbation of obstructive sleep apnea is vital for ensuring comprehensive patient care in orthodontic practice.
