Efficacy of Powered Intracapsular Tonsillectomy: A Single-Blinded Prospective Study

Area of Science:

• Otolaryngology
• Surgical Innovation
• Pediatric Surgery

Background:

• Powered intracapsular tonsillectomy (PIT) is a less invasive alternative to conventional extracapsular tonsillectomy (cTE).
• Previous studies on PIT efficacy were largely retrospective.
• Further clinical validation is needed to establish PIT's benefits.

Purpose of the Study:

• To evaluate the clinical utility of PIT versus cTE.
• To compare postoperative pain and complications between PIT and cTE.
• To conduct a single-blind, randomized controlled trial for robust comparison.

Main Methods:

• Prospective randomized controlled trial (WHO ICTRP ID: JPRN-UMIN000043776).
• Patients underwent either PIT (n=6) or cTE (n=5).
• Primary outcome: postoperative pain (FACES Pain Rating Scale); Secondary outcomes: analgesic use, diet, bleeding.

Main Results:

• The PIT group demonstrated a trend towards lower pain scores on postoperative days 2-4 (p=0.053).
• Significantly reduced analgesic consumption was observed in the PIT group (p<0.001).
• No significant differences in dietary intake or postoperative bleeding were noted between groups.

Conclusions:

• PIT is associated with significantly less analgesic use and a trend towards reduced pain.
• PIT appears to be a safe, minimally invasive alternative to cTE.
• This technique may promote earlier postoperative dietary advancement.
