Brief Summary

Enlarged tonsils and malocclusion have relationship with sleep disturbance in children. The consequences of these features can include deviation of normal craniofacial growth such that this may result in a facial morphology more suitable to the development of sleep apnea later in life. The aim of this study was to compare the growth redirection, the evolution of respiratory symptoms and the pharyngeal size of snoring children with obstructive tonsils from the waiting list for surgery treated with the Bioajusta X orthodontic appliance.This new protocol of orthodontic treatment promotes maxillary expansion, mandibular advancement and proper tongue positioning on swallowing , that together may be helpful on remodeling the upper airways.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of the facial growth

    Facial X rays exams were measured from both groups (treatment and control) and compared in a six month interval, in respect to sleep apnea predictors

    six months

Secondary Outcomes (1)

  • Pharyngeal Size

    six month

Study Arms (2)

Orthodontic treatment

EXPERIMENTAL

Snoring patients enrolling for tonsil surgery with maxillary constriction, and/or jaw retrognathism

Device: Bioajusta X Orthodontic treatment

Control Group

NO INTERVENTION

Patients enrolled for tonsils surgery

Interventions

Oral Appliance that promotes semi-rapid maxillary expansion, while corrects tongue positioning and jaws relationship

Also known as: Oral appliance, Orthodontic Treatment, Orofacial Orthopedics
