Intracapsular versus extracapsular dissection tonsillectomy for adults: A systematic review.

ABSTRACT

OBJECTIVES: Tonsillectomy is an extremely common ENT surgical procedure. There is a growing interest in the role of intracapsular dissection tonsillectomy (ICDT) due to reported reduced perioperative complications. We aim to compare the outcomes associated with ICDT versus traditional extracapsular dissection tonsillectomy (ECDT) in the adult population. METHODS: Systematic review of all randomized controlled trials (RCTs) comparing ICDT and ECDT for all indications in the adult population. Electronic searches performed through CENTRAL, PubMed, Ovid EMBASE, Web of Science, ClinicalTrials.gov, and WHO ICTRP. Review Manager 5.3 (RevMan 2014) was used to carry out the meta-analysis. RESULTS: Nine RCTs were included with a total of 11 reports with mean age of 23.9 years including 181 patients who received ICDT compared to 176 patients receiving ECDT. We found statistically significant reduced postoperative pain and analgesia requirement as well as a reduced rate of secondary postoperative bleeding in patients undergoing ICDT versus ECDT. There appears to be no significant difference in controlling recurrent tonsillitis between the ICDT and ECDT groups. CONCLUSION: Across the recorded outcomes we noted no clear benefit to performing ECDT over ICDT and evidence suggests high patient satisfaction with ICDT. Laryngoscope, 1302325-2335, 2020.
