Screening of Obstructive Sleep Apnea by Smartphone Homemade Video in Childood Snoring Population
A study testing smartphone homemade video in people with Obstructive Sleep Apnea Syndrome and Adeno-amygdala Hypertrophy, run by University Hospital, Clermont-Ferrand at 1 site in France.
Trial summary
The aim of the study is to evaluate the value of a video recording of the child sleep on smartphone made by the parents and comparing it to ventilatory polygraphy (PV) on the one hand and to the clinical evaluation method (clinical examination + Spruyt and Gozal score) on the other hand.

About this study
The aim of the study is to evaluate the value of a video recording of the child sleep on smartphone made by the parents and comparing it to ventilatory polygraphy (PV) on the one hand and to the clinical evaluation method (clinical examination + Spruyt and Gozal score) on the other hand.
Read the detailed description
Obstructive sleep apnoea syndrome (OSAS) is a common disorder in school-aged children with an estimated prevalence of 1-4%. The main etiology is adeno-amygdala hypertrophy. Adenoamygdalectomy, which involves the removal of tonsils and adenoids, is a common procedure. In the majority of cases, it allows the healing of OSAS. The surgical indication is currently based on clinical arguments sensitized by the calculation of a severity score (Spruyt and Gozal score). However, this procedure is not without complications: pneumopathy (for 1.5% of procedures), blood transfusion for haemorrhage (1/400 to 1/2 500), death due to haemorrhage (1/35 000 to 1/50 000).
Currently there is no indication to perform a preoperative sleep recording for this surgery. This recording will only be made in case of associated comorbidities (obesity, craniofacial malformations, neurological disorders...).
The current growth and diffusion of smartphones in the population provides a simple technical means of video recording the child's sleep. More and more parents come to an ENT consultation with a video recording of their child's sleep on a smartphone. The current recommendations say to take these data into account without any study having evaluated the value of such records. The video recording of a snoring child's sleep has already been evaluated by Sivan et al in 1996. This study finds a good correlation between polysomnographic recording and a method of rating video recordings of sleep in children with adeno-amygdala hypertrophy without associated comorbidities.
The aim of this study is therefore to evaluate the value of this video recording on smartphone made by the parents by comparing it to ventilatory polygraphy (PV) on the one hand and to the clinical evaluation method (clinical examination + SHS score) on the other hand. If our hypothesis is correct, smartphone video recording could be an additional tool to the clinical diagnosis of OSA in children with adeno-amygdala hypertrophy.

What is being measured
The primary outcome is the main question the study is designed to answer.
Video analysis score
The primary judging criterion will be the 10-minute video analysis score (independent variable). The dependent variable will be the status obtained with PV (pathological or normal), defined according to the standard criteria of the American Academy of Sleep Medicine 2012
Measured: at day 1
status obtained with PV
The primary judging criterion will be the 10-minute video analysis score (independent variable). The dependent variable will be the status obtained with PV (pathological or normal), defined according to the standard criteria of the American Academy of Sleep Medicine 2012
Measured: at day 1
Secondary outcomes (2)
Video analysis score
The secondary judging criterion will be the 10-minute video analysis score (independent variable). The dependent variable will be the status obtained with the score from the Spruyt and Gozal questionnaire (hierarchical SHS severity score) in its validated version in French.
Measured: at day 1

Questions about this trial
What is this clinical trial studying?
A study testing smartphone homemade video in people with Obstructive Sleep Apnea Syndrome and Adeno-amygdala Hypertrophy, run by University Hospital, Clermont-Ferrand at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 6 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: difficulty of recrutement). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Video analysis score (time frame: at day 1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03743558, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2026.
