Insights
Intracapsular tonsillectomy (IT) in children with developmental delays (DD) shows reduced hospital stays and less need for post-operative narcotics and steroids compared to extracapsular tonsillectomy (TT). Both methods effectively treat pediatric sleep apnea symptoms.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Developmental Pediatrics
Background:
- Outcomes of intracapsular tonsillectomy (IT) in children with developmental delays (DD) are not well-established.
- Comparison of IT versus extracapsular tonsillectomy (TT) outcomes in pediatric patients with DD is needed.
Purpose of the Study:
- To compare outcomes and complications of IT and TT in pediatric patients with DD.
- To compare outcomes and complications of IT and TT in non-developmentally delayed (NDD) children.
Main Methods:
- Retrospective study of pediatric patients undergoing tonsillectomy between 2016-2019.
- Included patients with Down Syndrome, Autism Spectrum Disorder, genetic syndromes, and global developmental delay.
- Analyzed outcomes and complications for IT and TT in DD and NDD cohorts.
Main Results:
- In the DD cohort, IT resulted in shorter hospital stays and reduced use of post-operative narcotics and steroids.
- IT and TT showed comparable efficacy in improving the Apnea Hypopnea Index (AHI) for pediatric sleep apnea.
- No statistically significant differences in emergency room visits or post-operative bleeding between IT and TT in the DD group.
Conclusions:
- Children with DD undergoing IT experience shorter hospital stays and reduced inpatient administration of opioids and steroids.
- IT demonstrates comparable efficacy to TT in treating pediatric sleep apnea with a potentially better safety profile.
- Further long-term studies are required to assess tonsil regrowth, revision surgery rates, and persistent obstructive sleep apnea (OSA).
Introduction:
Outcomes following intracapsular tonsillectomy (IT) have not been well established in children with developmental delays. The objective of this study was to compare outcomes and complications between intracapsular and extracapsular tonsillectomy (TT) in pediatric patients with developmental delay (DD) in comparison to non-developmentally delayed children.
Methods:
This is a retrospective study of pediatric patients with DD undergoing tonsillectomy between 2016 and 2019 at a tertiary care hospital. This group included patients with Down Syndrome, Autism Spectrum Disorder, other genetic syndromes, and patients with a diagnosis of global developmental delay. Outcomes and complications were analyzed for IT and TT.
Results:
2267 charts were reviewed, and 320 patients were identified with DD. Of those, 72 patients underwent IT and 248 underwent TT. In the DD cohort, the IT group had a shorter length of stay (0.97 vs 1.7 days, p < .0001) and was less likely to receive post-operative narcotic medication (2.8% vs 35%, p < .0001) and corticosteroids (9.7% vs 64%, p < .0001) during their hospital stay. Reductions in emergency room (ER) visits (5.6% vs 10%, p = .21) and post-op bleeding (PTH) (1.4% vs 4.8%, p = .31) for IT vs TT were not statistically significant in the DD group. In the NDD group, fewer patients undergoing IT returned to the ER (11% vs 2.3%, p < .0001) or had PTH (4.8% vs 0.25%, p, 0.0001) as compared to those children undergoing TT. There was no difference between parental report of symptom improvement between the groups (39% vs 33%, p = .39). Analysis of 180 patients with preoperative and postoperative sleep study data revealed post-op Apnea Hypopnea Index (AHI) improved with both techniques (74% TT vs 79% IT, p = .7). There were no differences noted for persistent obstructive sleep apnea (OSA) among the two techniques for both study groups (p = .63).
Conclusion:
Children with DD undergoing IT have reduced length of stay and reduced inpatient administration of post-operative opioids and steroids. IT has comparable efficacy to TT in treating symptoms of pediatric sleep apnea with a better safety profile. Overall, children undergoing IT return to the operating room less frequently than those undergoing TT. Longer follow-up studies will be needed to evaluate rate of tonsil regrowth, risk of revision surgery and persistence of OSA in these patients.
