Abstract

Aim: Obstructive sleep apnea syndrome (OSAS) is the most commontype of sleep apnea and it is caused by complete or partial obstruction of theupper airway. Adenotonsillar hypertrophy, obesity, cranio-facial anomaliesand neuromuscular diseases are the main risk factors for the development ofOSAS in the pediatric age. Specially several studies identify the relationshipbetween respiratory disorders in sleep and obesity, and, in particular, betweenOSAS and obesity, designing a prevalence of OSAS among obese subjectsbetween 14 and 78%. The diagnosis of OSAS in the child is of great importanceas it can lead to neurocognitive and behavioral complications, growthretardation, systemic arterial hypertension, pulmonary hypertension, cardiovasculardisease and metabolism.The WHO (World Health Organization) has established the new criteriafor the classification of Obesity on the basis of BMI and the risk of comorbidities,identifying a moderate risk for underweight subjects, a very low risk fornormal weights and an increased risk from severe to severe for overweightand obese individuals respectively.According to that the aim of this study is to evaluate the correlationbetween obstructive sleep apnea syndrome and cephalometric variables inchildren considering age and BMI.Materials and methods: Children aged 7–10 years and 11-14 years withno genetic syndrome, previous otorhinolaryngologic or orthodontic therapytreatments are being selected from our Departments of Paediatric Dentistry,University of Palermo, and from the Department of Orthodontics, Universityof Messina (Italy).All patients so far recruited and visited for orthodontic problems were inmixed or early permanent dentition phase, with the first upper molars fullyerupted and presented to the history of several symptoms of Osas, suchas recurring episodes of shallow or paused breathing during sleep, wakingup frequently to urinate, morning headaches, memory or learning problemsand not be able to concentrate or feeling irritable.Dental records and lateral cephalometric radiographs were obtained forall of the patients and than they have been subjected to paediatric, otolaryngologyand polysomnography visits.Subject with a positive diagnosis of Osas were studied and they weredivided in group based on their BMI.In all groups the inter-molar distance in dental records was measured, and the cephalometric traces have been calculated. As reported by the study by Galeotti et al. the cephalometric measurements analysed are S-PNS, ad1-PNS, and ad2-PNS for the nasopharynx; p-pp and pa for oropharynx; H-H’ for the Hyoid bone; SNA for the maxilla; SNB;ANB and Go-Me for the mandible;S-Go, N-Me and P-A for facial Height; SN for cranial base; SN-MP and PP-MP for the typology, and angle ArGoMe for Growth prevision.At the time that children are still in the way of recruitment the results may not yet be defined; however it is necessary to emphasize the importance of the study, because in the child respiratory disturbances in the sleep, and in particular the OSAS, are often underestimated, despite representing the third place between the threats of health after the smoke and the excess of weight.
