Surgical correction of obstructive sleep apnea in the complicated pediatric patient documented by polysomnography
Insights
Surgical treatment, including tonsillectomy and adenoidectomy, effectively resolves obstructive sleep apnea (OSA) in children. Procedures significantly improved sleep apnea metrics and oxygen levels in a diverse pediatric patient group.
Area of Science:
- Pediatric Otolaryngology
- Sleep Medicine
- Surgical Research
Background:
- Obstructive sleep apnea (OSA) is a common condition in children, often requiring surgical intervention.
- Surgical outcomes in diverse pediatric populations with OSA are not always well-defined.
- Evaluating the effectiveness of common surgical procedures for pediatric OSA is crucial for treatment planning.
Purpose of the Study:
- To assess the efficacy of surgical treatments for obstructive sleep apnea (OSA) in a varied group of pediatric patients.
- To analyze polysomnographic data before and after surgery to quantify treatment success.
- To determine if surgical interventions benefit children with co-existing medical conditions.
Main Methods:
- A retrospective case series analyzed pre- and post-operative polysomnograms (PSG) from 48 pediatric OSA patients.
- Patients underwent various surgical procedures, including tonsillectomy and adenoidectomy (T and A), with or without uvulopalatopharyngoplasty (UPPP).
- Key outcome measures included apnea/hypopnea index (AHI), oxygen saturation, and end-tidal pCO2 levels.
Main Results:
- Mean AHI significantly decreased from 27 to 6 post-surgery (P < 0.001), with 54% achieving an AHI < 5.
- Percent sleep with oxygen saturation below 90% improved from 17.9% to 1.4% (P < 0.001).
- Percent sleep time with end-tidal pCO2 > 50 decreased from 22.3% to 12.6% (P < 0.01), indicating improved ventilation.
Conclusions:
- Tonsillectomy, adenoidectomy, and UPPP are effective surgical treatments for pediatric OSA across diverse patient groups.
- Significant improvements were observed in children with comorbidities such as asthma, cerebral palsy, Down syndrome, and morbid obesity.
- Surgical management offers a viable therapeutic option for improving sleep-disordered breathing in children with complex medical histories.
Objective:
Evaluate the effectiveness of surgical treatment of obstructive sleep apnea in a diverse population of children.
Design:
A retrospective case series of pre and post operative polysomnograms (PSG) of pediatric patients with obstructive sleep apnea (OSA).
Setting:
Tertiary care children's hospital.
Patients:
48 patients in whom sleep studies were performed pre-operatively for either an unclear history and/or physical findings or complicated OSA. Thirteen patients had no complicating medical factors, 35 patients had various associated medical problems, including 20 with morbid obesity, five with Down syndrome, four with asthma, two with cerebral palsy, and four other. The average age was 7.5 years with a range of 1.5-20 years.
Interventions:
Thirty-one patients had a tonsillectomy and adenoidectomy (T and A) only, 13 had T and A with uvulopalatopharyngoplasty (UPPP), and three had tonsillectomy and UPPP.
Main Outcome Measures:
Pre and postoperative PSG results including apnea/hypopnea index (AHI), percent of sleep with oxygen saturation below 90%, and percent sleep time with end-tidal pCO2 > 50.
Results:
The mean pre-operative (AHI) was 27 +/- 4 (mean +/- S.E.M.) and post operatively was 6 +/- 1 (P < 0.001). Twenty six of 48 (54%) had a postoperative AHI of less than five. Pre-operative percent of sleep with oxygen saturation below 90% was 17.9 +/- 4.5%, post-operatively it was 1.4 +/- 0.1% (P < 0.001). Pre-operative percent sleep time with end-tidal pCO2 > 50 was 22.3 +/- 3.4%, post operatively it was 12.6 +/- 2.9% (P < 0.01). UPPP was performed more commonly in patients with Down syndrome. There was a trend toward more improvement in patients who had T and performed than those undergoing UPPP (post op AHI of 4.7 vs. 7.4 respectively).
Conclusions:
Tonsillectomy, adenoidectomy and UPPP are effective in the treatment of OSA in a diverse group of pediatric patients. Patients with asthma, cerebral palsy, Down syndrome, morbid obesity, and hereditary syndromes all improved significantly with surgical management.
