Safety of outpatient admission and comparison of different surgical techniques in adult tonsillectomy.

PURPOSE: To investigate the safety of outpatient admission and the effects of surgical technique in tonsillectomy operations of adult patients.

METHODS: The digital database was scanned for patients aged ≥ 15 years that underwent tonsillectomy in our institution between years 2014 and 2018. Demographic and clinical characteristics, the surgical technique, length of stay (LOS) in hospital, re-admissions after discharge, complications and interventions performed were recorded.

RESULTS: A total of 276 patients met the inclusion criteria, comprising 139 (50.4%) females and 137 (49.6%) males with a mean age of 27.17 ± 9.41 years. The most common indication was recurrent tonsillitis (n = 223, 80.8%), and surgical techniques used were bipolar scissors (CURIS® , Sutter Medizintechnik, Germany) (n = 137, 49.6%), cold dissection (n = 75, 27.2%) and/or plasma blade (PEAK Surgical, Medtronic, USA) (n = 64, 23.2%). A total of 43 (15.5%) re-admissions from 37 (13.4%) patients were recorded because of bleeding (n = 33, 70.2%) and/or odynodysphagia (n = 13, 27.7%). Non-surgical interventions were sufficient in 32 (74.4%) cases, while surgical interventions were required in 11 (25.6%) patients. In patients where "hot" techniques (bipolar scissors, plasma blade) were used and in patients with complaints in the first 24 h postoperatively, significantly increased rates of elongated LOS values for more than 1 day were determined (p < 0.01, p < 0.001).

CONCLUSIONS: Adult tonsillectomy is a safe surgical procedure with low complication, re-operation and mortality rates. Significantly increased rates of elongated LOS values for more than 1 day and re-admissions after discharge were determined in those patients having complications in the first 24 h postoperatively. Cold dissection seems to be more advisable than hot techniques for outpatient tonsillectomy among adult patients.
