INTRODUCTION

Powered intracapsular tonsillectomy (PIT) is a technique that protects the tonsillar capsule by using a microdebrider, resulting in faster wound-healing and reduced suffering. Many studies have found PIT to be effective, particularly in pediatric patients with obstructive sleep apnea (OSA). However, previous studies have not included patients with a history of recurrent tonsillitis.

OBJECTIVE

The aim of this study was to determine the efficacy of PIT in pediatric patients even with a history of recurrent tonsillitis, and therefore, we want to expand the indication for PIT and reveal its safety.

METHODS

A total of 886 pediatric patients underwent PIT between February 2013 and March 2016. All patients rated their postoperative pain using a visual analog scale (VAS) and completed the Korean obstructive sleep apnea (KOSA)-18 questionnaire for assessment of their quality of life (QOL). There were 539 males and 347 females. Their mean age was 6.2 years (range 2-14 years). The majority (77.7%) underwent the operation for OSA, and the rest (22.3%) had a history of recurrent tonsillitis. To compare the efficacy of PIT with traditional tonsillectomy, we selected 191 patients who underwent extracapsular tonsillectomy (ECT), a conventional technique, during the same time period. The median follow-up period was 16.7 months. During the follow-up period, instances of delayed bleeding and recurrent pharyngitis were monitored.

RESULTS

In comparison to the patients who underwent ECT, the PIT group showed significantly fewer cases of postoperative bleeding (p = 0.027). Thirteen patients in the PIT group (1.5%) visited the hospital during the follow-up period for pharyngitis, while 8 in the ECT group (4.2%) visited for pharyngitis. The mean postoperative pain score, as assessed by a VAS, was 4.6 ± 3.2, and pain improved within an average of 2.9 days after surgery in the PIT group. The mean KOSA-18 score for the QOL of the patients was 65.9 preoperatively and 35.6 postoperatively in the PIT group.

CONCLUSIONS

Pediatric tonsillectomy using PIT is valid for reducing postoperative pain and improving the QOL of OSA patients. PIT is also effective and safe for patients with a history of recurrent tonsillitis.
