Beskrivelse
Inclusion Criteria:
- children (younger than 18 years old and older than 2 years old) with symptoms of snoring and then were confirmed to having obstructive sleep apnea/hypopnea syndrome by a comprehensive polysomnography
Exclusion Criteria:
- patients with substance abuse problems or the long-term usage of medications known to affect sleep, craniofacial abnormalities or neuromuscular disorders, Down syndrome, cerebral palsy, mucopolysaccharidoses, Prader-Willi syndrome, history of psychosis, central sleep apnea syndrome, or previous airway surgery including tonsillectomy and/or adenoidectomy were excluded from the study.

Tidsramme |
|---|---|---|
|
Clinical predictors for apnea/hypopnea index (AHI)
Tidsramme: up to 4 months
|
When all variables were analyzed individually with the AHI, Spearman rank correlation analysis was used to explore the relationships between clinical predictor variables and AHI.Significant variables were entered into stepwise multiple linear regression analysis to identify independent predictors for pediatric OSAHS and to develop a predictive equation for AHI values.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Anthropometric measurements: body mass index z-score (BMI z-score)
Tidsramme: up to 4 months
|
BMI z-score: a measure of relative weight adjusted for the child's age and gender, and calculated by dividing the difference between the measured value and the mean by the standard deviation.
|
up to 4 months
|
|
Anthropometric measurements: tonsil size grading
Tidsramme: up to 4 months
|
Tonsil size grading: 0, surgically removed tonsils; 1, tonsils hidden within the pillars; 2, tonsils extending to the pillars; 3, tonsils were beyond the pillars but not to the midline; and 4, tonsils extended to the midline.
|
up to 4 months
|
|
Anthropometric measurements: modified Mallampati grade (aka updated Friedman's tongue position
Tidsramme: up to 4 months
|
updated Friedman's tongue position: I: visualization of the entire uvula and tonsils/pillars.;
IIa: visualization of most of the uvula, but the tonsils/pillars are absent.;
IIb: visualization of the entire soft plate to the base of the uvula.;
III: visualization of some of the soft palate, but the distal structures are absent.;
IV: visualization of the hard palate only.
|
up to 4 months
|
|
Anthropometric measurements: uvular length
Tidsramme: up to 4 months
|
uvular length in centimeter
|
up to 4 months
|
|
Snoring visual analogue scale (Snoring VAS)
Tidsramme: up to 4 months
|
Snoring VAS (Units on a Scale): 0-10, 0 = "no snoring noise" and 10 = "the loudest sound imaginable
|
up to 4 months
|
|
Apnea/hypopnea index (AHI)
Tidsramme: up to 4 months
|
AHI: total number of apneas and hypopneas per hour of electroencephalographic sleep.
|
up to 4 months
