Overview
OSAHS (Obstructive Sleep Apnea Hypopnea Syndrome) in children is a frequent respiratory disorder, whose prevalence is estimated at between 1.2 and 5.7%, and which, if left untreated, can cause severe medical complications. This prevalence tends to be underestimated. Diagnosis is made following a clinical examination noting the presence of characteristic clinical and polysomnographic criteria. Multidisciplinary management has been widely described in the literature, and various therapeutic options have been indicated. Rapid maxillary expansion has proved highly effective in the treatment of this condition. This syndrome is a real public health problem and must be diagnosed as early as possible. Through our research, we would like to study whether there is a causal link between an orthodontic problem of the transverse direction and the presence of SAHOS in children. In other words, we would like to assess whether children who clinically present an orthodontic deficiency of their transverse dimension are more likely to develop SAHOS than children without this deficit. If this proves to be true, then a new clinical sign could enable certain healthcare professionals to detect this syndrome early, and be able to refer patients to physicians as soon as possible.
Interventions
- Diagnostic test over nigtht ventilatory polysomnograph test
Every patient will have an overnight polysomnography test.
Primary outcome measures
- study whether children with a transverse orthodontic deficiency have a higher risk of developing Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) compared to those without this deficiency, [Time frame: 1 months after enrollement]
Secondary outcome measures (4)
- study whether all children with a transverse orthodontic deficiency systematically have Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) [Time frame: one month after enrollement]
- Investigate a link between the severity of this transverse deficiency and the severity of OSAHS. [Time frame: 1month after enrollement]
- impact of hteSeverity of transferse deficiency on the snoring events frequency. [Time frame: 1months after enrollement]
- diagnostic value of the sleep disorder screening scale for children aged 4 to 16 years [Time frame: 1month after enrollement]
