Quality of life and sleep study findings after adenotonsillectomy in children with obstructive sleep apnea.

OBJECTIVES: To assess polysomnogram (PSG) results and global and disease-specific quality of life (QOL) in children with obstructive sleep apnea (OSA), before and after adenotonsillectomy, and to assess the association between PSG findings and QOL. DESIGN: Prospective observational study. We performed overnight PSG using standardized techniques and assessed disease-specific and global QOL using validated instruments. Follow-up was assessed at 1 year. We compared QOL outcomes between children who underwent adenotonsillectomy and children who did not. SETTING: A large tertiary care children's hospital. PATIENTS: Children with sleep-disordered breathing who were suspected of having OSA. INTERVENTION: Adenotonsillectomy. MAIN OUTCOME MEASURES: We evaluated PSG parameters, disease-specific QOL, and global QOL. RESULTS: We enrolled 47 children, 31 of whom met PSG criteria for OSA. Disease-specific and global QOL were not significantly different between children with OSA and children without. Global QOL was significantly worse for children with OSA than healthy children on several subscales: general health perception, behavior, and parental impact-emotional. Children who underwent adenotonsillectomy had significant improvements in QOL scores and PSG parameters (apnea-hypopnea index, P = .004; minimum saturation, P = .004). We found significantly larger QOL changes in children who underwent surgery compared with children without surgery (subscales: infections, P = .01; airway, P = .002; swallowing, P = .02; and behavior, P = .03). No strong association was identified between QOL scores and PSG parameters. CONCLUSIONS: Children with OSA and sleep-disordered breathing have significantly worse QOL than healthy children. However, the association between PSG findings and QOL was only moderate. Children with OSA treated with adenotonsillectomy demonstrated large improvements in disease-specific and global QOL as well as PSG parameters.

Adenotonsillectomy for obstructive sleep apnea in obese children: effects on respiratory parameters and clinical outcome.

OBJECTIVE: To assess the efficacy of adenotonsillar surgery on respiratory sleep parameters and avoiding continuous positive airway pressure (CPAP) treatment in morbidly obese children with obstructive sleep apnea syndrome (OSAS). DESIGN: Retrospective. SETTING: Tertiary referral institution. PATIENTS: Children aged 2 to 18 years, with a body mass index (BMI) at or higher than the 95th percentile (adjusted for age and sex), undergoing adenotonsillar surgery for OSAS. INTERVENTIONS: Adenotonsillectomy. MAIN OUTCOME MEASURES: Preoperative and postoperative respiratory disturbance index, oxygen saturation nadir, overall severity of OSAS (mild, moderate, or severe) and candidacy for CPAP treatment were assessed and compared. Variables such as age, severity of disease, adenotonsillar size, and BMI z scores were compared between responders and nonresponders to surgical treatment. RESULTS: A total of 19 patients with full preoperative and postoperative data for evaluation were identified. The median (SD) age was 78 months (53.3 months). The median (SD) BMI z score was 2.84 (0.94). Eighteen patients (95%) had OSAS preoperatively to warrant CPAP treatment. Surgery reduced the overall median (SD) respiratory disturbance index from 20.7 (24.5) to 7.3 (14.9) (P<.001) and improved the median (SD) oxygen saturation nadir from 77.5% (16.3%) to 88.5 (13.1%) (P<.01). A total of 7 patients (37%) were cured by surgery. Ten patients (53%) had postoperative disease of sufficient severity to require CPAP. Surgery obviated the need for further treatment in only 8 (44%) of the 18 patients with preoperative disease warranting CPAP. No differences were identified between responders and nonresponders to surgical treatment. CONCLUSIONS: Adenotonsillar surgery improves sleep respiratory parameters in morbidly obese children with OSAS. Most patients have residual OSAS requiring further treatment.

Postoperative recovery after microdebrider intracapsular or monopolar electrocautery tonsillectomy: a prospective, randomized, single-blinded study.

OBJECTIVE: To prospectively assess the postoperative recovery in patients randomly selected to receive either microdebrider intracapsular tonsillectomy (MT) or monopolar electrocautery tonsillectomy (ET). DESIGN: A prospective, randomized, single-blinded study. SETTING: Tertiary care children's hospital. PATIENTS: A total of 74 patients between the ages of 3 and 7 years undergoing adenotonsillectomy for obstruction were randomly assigned to the MT and ET groups. MAIN OUTCOME MEASURES: Families were blinded to the technique used and given a checklist to fill out daily quantifying pain, activity, diet, and the number of doses of pain medication given over a 10-day period. Other variables assessed included the time of surgery and intraoperative blood loss. RESULTS: The average time of surgery was 16.9 minutes for ET compared with 20.9 minutes for MT (P<.001). The average blood loss was 30 mL for ET compared with 45 mL for MT (P = .01). Resumption of near-normal dietary intake was achieved 1.7 days earlier in patients receiving MT compared with ET (P = .04). There was no significant difference in the number of days taken for the resolution of pain or resumption of normal activity between the 2 groups. CONCLUSIONS: Microdebrider tonsillectomy takes over 4 minutes longer to perform compared with ET and has slightly higher intraoperative blood loss. There appears to be a slight advantage in the resumption of normal dietary intake with MT but no significant difference in the number of days taken for the resolution of pain or resumption of normal activity.

Adenotonsillectomy for obstructive sleep apnea syndrome in young children: prevalence of pulmonary complications.

OBJECTIVE: To determine, in a series of children younger than 6 years undergoing adenotonsillectomy for treatment of clinical obstructive sleep apnea syndrome (OSAS), the effect of age on prevalence of postoperative respiratory complications. The primary objective was to define a practice standard for postoperative hospital admission. DESIGN: Retrospective analysis. SETTING: Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio. PATIENTS: All children younger than 6 years who underwent adenotonsillectomy to treat OSAS from June 1, 1999, to May 31, 2001. MAIN OUTCOME MEASURES: The percentage of children younger than 3 years undergoing adenotonsillectomy to treat OSAS who experience a postoperative respiratory complication. RESULTS: Of 2315 patients younger than 6 years undergoing an adenotonsillectomy for treatment of OSAS, 149 (6.4%) developed a postoperative respiratory complication. Even though there was a lower incidence of comorbid medical conditions in this cohort, children younger than 3 years were at a greater risk for developing a postoperative respiratory complication compared with those aged 3 to 5 years (9.8% vs 4.9%, P<.001). Logistic regression analysis revealed that children younger than 3 years had a nearly 2-fold increased risk for respiratory complications postoperatively (odds ratio, 1.98; 95% confidence interval, 1.41-2.77) when controlling for race and sex. CONCLUSIONS: Adenotonsillectomy to treat OSAS is associated with a significantly higher rate of postoperative respiratory complication in children younger than 3 years compared with children aged 3 to 5 years. Our results support hospital admission for all patients younger than 3 years undergoing adenotonsillectomy for treatment of OSAS.
