Normal palatine tonsil size in healthy children: a sonographic study

Area of Science:

• Pediatric imaging
• Otolaryngology
• Diagnostic ultrasound

Background:

• Magnetic resonance imaging (MRI) and computerized tomography (CT) are common but costly and resource-intensive methods for evaluating palatine tonsils.
• Ultrasound (US) offers a cost-effective, radiation-free alternative for tonsil assessment.
• Limitations of current imaging techniques necessitate defining normative data for pediatric tonsils.

Purpose of the Study:

• To establish normal palatine tonsil (PT) size and volume reference ranges in healthy children.
• To investigate the correlation of PT size with age, height, weight, and body mass index (BMI).

Main Methods:

• Ultrasound measurements of palatine tonsil (PT) dimensions were performed on 274 healthy children.
• Children were categorized into six age subgroups for detailed analysis.
• Correlation analysis was conducted between PT dimensions and demographic/anthropometric data (age, sex, height, weight, BMI).

Main Results:

• Mean palatine tonsil (PT) volume was 1.5 ± 0.9 cm³ for both right and left tonsils.
• Significant positive correlations were observed between PT volume and height, weight, and BMI.
• No significant correlation was found between PT volume and sex or laterality.

Conclusions:

• Ultrasound (US) is a feasible and effective diagnostic tool for palatine tonsil (PT) pathologies.
• Palatine tonsil (PT) size is significantly influenced by age, height, weight, and BMI in children.
• Establishing normative US data for PT size is crucial for accurate pediatric diagnosis.
