[Dentofacial development abnormalities in paediatric sleep-related breathing disorders].

Introduction: The recent interest in sleep-related breathing disorders has re-opened the old debate as to whether there is a causal relationship between upper respiratory obstruction and abnormalities in dentofacial development.

Objective: To establish the impact of dentofacial development on sleep-related breathing disorders in children.

Method: This is a prospective study in which the dentofacial studies of 30 children, diagnosed with a sleep-related breathing disorder using polysomnography, were compared with a control group of 30 healthy children.
