Mallampati score and pediatric obstructive sleep apnea
Insights
The Mallampati score and tonsillar size can help predict obstructive sleep apnea (OSA) in children. These simple oral examination findings may help identify children needing further polysomnography (PSG) testing.
Area of Science:
- Pediatric Sleep Medicine
- Otolaryngology
- Diagnostic Tools
Background:
- Pediatric obstructive sleep apnea (OSA) is a prevalent condition.
- Delayed diagnosis of pediatric OSA leads to significant morbidity.
- Access to polysomnography (PSG), the gold standard for diagnosis, is limited due to a shortage of pediatric sleep specialists.
Purpose of the Study:
- To evaluate the effectiveness of the Mallampati score (sitting and supine) in predicting the presence and severity of OSA in children.
- To determine if simple physical examination findings can aid in OSA diagnosis.
Main Methods:
- A retrospective analysis of 158 children from a single pediatric sleep center.
- Data collected included polysomnography (PSG) results and physical examinations documenting Mallampati score and tonsillar size.
- Statistical analysis, including odds ratios, was used to assess the correlation between Mallampati score, tonsillar size, and the apnea-hypopnea index (AHI).
Main Results:
- A significant positive correlation was observed between Mallampati score, tonsillar size, and AHI.
- Each one-point increase in Mallampati score was associated with a greater than 6-fold increase in the odds of having OSA.
- Each one-point increase in tonsillar size was associated with a greater than 2-fold increase in the odds of having OSA.
Conclusions:
- The Mallampati score and tonsillar size are independent predictors of pediatric OSA.
- Incorporating oral examinations, including Mallampati score and tonsillar size assessment, is recommended for evaluating children for OSA.
- These clinical findings can assist in prioritizing children who require polysomnography (PSG).
Rationale:
Pediatric obstructive sleep apnea (OSA) is common, and a delay in diagnosis can lead to significant morbidity. Polysomnography (PSG) is the gold standard for the diagnosis of OSA. However, difficulty accessing PSG due to the relative shortage of sleep centers with pediatric expertise can lead to a delay in the diagnosis and management of OSA.
Objectives:
To assess the utility of Mallampati score (sitting and supine) in predicting the presence and severity of OSA in children.
Methods:
A retrospective study of 158 children from a single pediatric sleep center. All patients had a PSG and a physical examination documenting Mallampati score. The Mallampati score, tonsillar size, age, sex, and apnea hypopnea index (AHI) were analyzed. Odds ratio of having pediatric OSA (AHI > 1) with increase in Mallampati score and tonsillar size were calculated.
Measurements And Main Results:
A significant correlation was found between Mallampati score, tonsillar size, and AHI. For every point increase in the Mallampati score, the odds ratio of having OSA increased by more than 6-fold. For every point increase in tonsillar size, the odds ratio of having OSA increased by more than 2-fold.
Conclusions:
Mallampati score and tonsillar size are independent predictors of OSA. Oral examination including Mallampati score and tonsillar size should be considered when evaluating a patient for OSA. They can be used to prioritize children who may need PSG.
