Changes in body composition and growth pattern after adenotonsillectomy in prepubertal children

Area of Science:

• Pediatric Otolaryngology
• Pediatric Endocrinology
• Pediatric Nutrition

Background:

• Adenotonsillar hypertrophy and chronic tonsillitis can impede childhood growth.
• Adenotonsillectomy is linked to improved growth and Body Mass Index (BMI).
• No studies have examined adenotonsillectomy's impact on body muscle and fat composition.

Purpose of the Study:

• To assess the effect of adenoidectomy and adenotonsillectomy on body muscle and fat composition.
• To evaluate changes in prepubertal children following these surgical procedures.

Main Methods:

• Prospective study of 30 prepubertal children undergoing adenoidectomy or adenotonsillectomy, followed for 6 months.
• Comparison with 28 age-matched healthy controls over the same period.
• Bioelectrical impedance analysis used to measure body composition, BMI z-scores, and basal metabolic rate.

Main Results:

• Significant increases in body muscle mass and basal metabolic rate observed post-surgery.
• Relative BMI scores significantly improved in the surgical group.
• No significant differences in body fat mass, body fat percentage, or BMI z-scores between groups.

Conclusions:

• Adenotonsillectomy promotes healthy weight gain in prepubertal children.
• Surgery leads to improved relative BMI without increasing body fat percentage.
• Muscle mass and metabolic rate increase post-adenotonsillectomy.
