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.",[92,93],"Obstructive Sleep Apnea","Transverse Maxillary Deficiency","2026-03-27",{"date":96,"type":97},"2026-03-30","ACTUAL",{"date":99,"type":97},"2025-11-06",{"date":101,"type":86},"2026-09-30",{"name":5,"class":6},1]
