Post-Tonsillectomy Morbidity and Quality of Life in Pediatric Patients with Obstructive Tonsils and Adenoid: Microdebrider vs Electrocautery

Objective

To prospectively compare outcomes in children over age 2 with obstructive adenotonsillar hypertrophy when tonsillectomy is performed utilizing an intracapsular microdebrider technique versus low-wattage electrocautery technique.

Study design and setting

Prospective, single-blind, randomized controlled trial at a tertiary care children’s hospital.

Results

Among the 300 children, those treated with the microdebrider resumed normal activity faster, with a median recovery of 2.5 days, and stopped taking pain medication sooner, with the median time to the last dose of 4 days. The microdebrider group were 3 times more likely to no longer need pain medications at 3 days postoperatively and 2.5 times less likely to be still needing pain medication 7 days postoperatively. They were twice as likely to be at a normal activity level by 3 days postoperatively and were less likely to still not have attained normal activity and normal diet after 7 days. There was no difference between groups in median days to return to normal diet (3.0 to 3.5 days). At 1-month follow-up, children in the microdebrider group were 5 times more likely to have residual tonsil tissue.

Conclusions

Intracapsular tonsillectomy in children with obstructive adenotonsillar hypertrophy results in improved peri-operative outcomes. Residual tonsil tissue is more common with use of the microdebrider; however, the incidence of future obstruction or infection is unknown.
