Pharyngeal Size in Patients With Obstructive Tonsils Under Orthodontic Treatment

2014-07-23 21:07:41 | BioPortfolio

Summary

Enlarged tonsils and malocclusion has relationship with sleep disturbance in children. The consequences of these features can include aggravation of craniofacial growth such that the development results in a facial morphology more suitable to develop 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 upon swallowing , that together may be helpful on remodeling the upper airways.

Description

Methods-The study population included 40 children, ranging in age from 6 to 9 years old, who were on the waiting list for adenotonsillectomy at the ENT Department of FMUSP. The patients were randomly divided into two groups and were subsequently compared after a six month interval. The first group included 24 patients who where treated with the Bioajusta X appliance and the second group included 16 patients who served as controls, and,thus, did not received any treatment. Cephalometric analysis was used to assess the growth direction by comparing the relationship of the vertical jaw based upon the angle of the palatal plane with the mandibular plane (ANS-PNS/Go-M).Pharyngeal size was measured using acoustic pharyngometry. The parents filled out a questionnaire with respect to the respiratory symptoms of their children.

Medical and Biotech [MESH] Definitions

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)

Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)

HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.

A dental health survey developed to evaluate a patient's orthodontic treatment need and priority for orthodontic care. The index is based on an assessment of degree of MALOCCLUSION and the potential aesthetic and dental health benefit of the treatment under consideration.
