Intracapsular Versus Total Tonsillectomy in Patients with Trisomy 21

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Sleep Medicine

Background:

• Intracapsular tonsillectomy and adenoidectomy (iTA) is increasingly preferred for pediatric obstructive sleep apnea (OSA) due to a favorable recovery profile.
• Trisomy 21 (T21) presents unique challenges for OSA management, often necessitating surgical intervention.

Purpose of the Study:

• To compare the surgical recovery and impact on OSA between iTA and extracapsular tonsillectomy and adenoidectomy (TT) in patients with T21.
• To evaluate postoperative pain, complications, and long-term OSA outcomes in T21 patients undergoing these procedures.

Main Methods:

• A retrospective case series involving T21 patients who underwent either iTA or TT between July 2015 and August 2022.
• Data collection included demographics, comorbidities, sleep study results, surgical details, recovery metrics, and follow-up information.

Main Results:

• The iTA group demonstrated significantly lower pain scores, reduced narcotic use, shorter hospital stays, and faster return to oral intake.
• Fewer 30-day complications were observed in the iTA group compared to the TT group.
• Both iTA and TT resulted in significant improvements in sleep study parameters, with no significant difference in OSA symptoms or tonsillar regrowth at long-term follow-up.

Conclusions:

• iTA is associated with less postoperative pain and fewer respiratory complications in T21 patients compared to TT.
• The short-term efficacy of iTA and TT in improving OSA, as assessed by polysomnography, is comparable.
• Further research may explore long-term differences and optimal surgical approaches for T21 patients with OSA.
