Children's Behavior May Improve After Adenotonsillectomy

After 2.5 years, improvements in sleep not as great as those observed after six months

MONDAY, July 20 (HealthDay News) -- In children who undergo adenotonsillectomy for sleep-disordered breathing, improvements in sleep and behavior occur but may not be exactly maintained over time or reach baseline levels, according to a study published in the July issue of the Archives of Otolaryngology - Head & Neck Surgery.

Julie L. Wei, M.D., of the University of Kansas School of Medicine in Kansas City, and colleagues compared data collected on 44 children six months after adenotonsillectomy with data obtained 2.4 to 3.6 years after surgery.

During follow-up, the researchers found that Pediatric Sleep Questionnaire scores significantly increased at 6 months post-surgery, but were not as great at 2.5 years following surgery. They also found mildly significant improvements in behavior -- as measured by the Conners Parent Rating Scale-Revised: Short Form -- that were maintained in all categories except for the attention-deficit/hyperactivity disorder index.

"Several studies have demonstrated improvement in behavior, cognition, and quality of life after adenotonsillectomy for sleep-disordered breathing using validated instruments, but because of the absence of randomized trial data, the definitive evidence for the efficacy of adenotonsillectomy for sleep-disordered breathing has not yet been fully demonstrated," the authors conclude.
