Comparison of Two Oral Myofunctional Reeducation Methods for Children With Obstructive Sleep Apnea (PERSIST-B)

March 27, 2024 updated by: Nelly Huynh, Université de Montréal

Comparison of Two Oral Myofunctional Reeducation Methods for Children With Obstructive Sleep Apnea Before Adenotonsillectomy : a Randomized Controlled Trial.

Myofunctional therapy has been shown to be effectively reduce symptoms of paediatric sleep apnea. As the effectiveness of reeducation relies on parental involvement and child's compliance, the investigator's research question was to evaluate two methods of myofunctional therapy (daily oral exercices versus a flexible oral appliance, both in combination with nasal hygiene), compared to nasal hygiene alone (control group).

Detailed Description

Introduction: Paediatric Obstructive Sleep Apnea (OSA) is a multifactorial condition, associated with significant comorbidities, affecting cardiovascular health, cognitive development and quality of life. Its main cause is adenotonsillar hypertrophy, but some co-factors such as obesity, orofacial dysfunctions and craniofacial abnormalities contribute to the severity of symptoms or their persistance after adeno-tonsillectomy.

Aim : Myofunctional therapy has been shown to reduce Apnea-Hyponea indexes (AHI) of children, and can serve as an adjunct to other therapies, but the level of compliance is a limiting factor. The investigator's aim is to evaluate two methods of oral reeducation in a group a children scheduled for adeno-tonsillectomy (in association with nasal hygiene) and to compare them with nasal hygiene alone (control group).

Methods : The design of the study is a randomized Controlled Trial, enrolling 60 children with significant obstructive sleep apnea and divided into 3 groups : Group 1 following daily oral exercises (+nasal hygiene), Group 2 using of a flexible oral appliance during quiet activities and sleep (+nasal hygiene), and Group 3 using nasal hygiene alone (control group). The objective assessment of sleep parameters is performed at home using an ambulatory device (AHI, desaturation index, minimal oxygen saturation, flow limitation, snoring), before and after therapy, in a 3 months interval. An orthodontic and craniofacial assessment, the examination of orofacial functions and tongue/lip strength measurements (IOPI system), as well as quality of life questionnaires (OSA-18) are also performed on participants, before and after therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

5 years to 14 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria: participants must:

  • present signs of obstructive sleep apnea: snoring, apnea / respiratory pauses audible by the entourage (objectivized by a score, to the hierarchical questionnaire of severity of Spruyt and Gozal, greater than or equal to 2,72- This questionnaire comprises six Questions and has a good sensitivity (60%) and specificity (82%) in screening for pediatric sleep apnea.
  • be programmed for adenoidectomy, tonsillectomy or adeno-tonsillectomy within 3 months (or more).

Exclusion Criteria: participants should not:

  • present with a craniofacial syndrome nor a severe medical condition with complex medical management,
  • present with an abnormality of the neuromuscular tone (such as Duchenne myopathy or cerebral palsy)
  • receive orthodontic therapy during the study
  • have a class III malocclusion (mandibular prognathy type), for which a propulsion oral appliance is contraindicated because it may aggravate mandibular prominence. Maxillary deficiency is not a exclusion criterion.
  • A non-nutritive oral habit such as digital sucking (or pacifier) that persists because it interferes with oral reeducation, and is a contraindication to orthodontic treatments. Children who have recently stopped such a habit may be included in the study.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Myofunctional Oral Exercices
Parents and participants of this group will receive instructions for nasal and oral myo-functional exercises, to perform at home each day, for 5 to 10 minutes. A booklet (measure of adherence) and an Phone application for Android/Apple with descriptions/videos of those exercices will be given to them. These exercises will include nasal hygiene procedures, nasal cartilage exercices, lingual posture rehabilitation exercises, lip tone enhancement exercises, and swallowing rehabilitation exercises.
Procedure: Oral Myofunctional Therapy with exercices
Oral-Motor training of oral muscles (tongue, lips) associated with nasal hygiene with daily repetition of exercices and parental support.
Other Names:
  • Oral reeducation
Experimental: Soft Oral Appliance
Parents and participants will be instructed in wearing the soft/flexible oral appliance and how to perform nasal hygiene in order to better tolerate the device. The oral appliance comes in several sizes, adapted to the age of the child; it is constructed in a soft elastomer material, in a position of slight propulsion and opening of the mandible to help clear the pharynx. It has a ramp to guide the tongue in a good position, a labial screen to stretch the labial strap and prevent the tongue from protruding between front teeth.
Procedure: Oral Myofunctional Therapy with soft oral appliance
Ora-Motor training of oral muscles (tongue, lips) associated with nasal hygiene, with reduced parental support.
Other Names:
  • Oral Trainer
No Intervention: Control Group
Parents and Participants of this group will be reminded the nasal hygiene procedures (application of saline in each nostril three times a day), and given a diary to report daily use.
