Coblation tonsillectomy versus coblation tonsillectomy with ties in adults

OBJECTIVE: This study was performed to compare the intraoperative and postoperative courses of coblation tonsillectomy and coblation tonsillectomy with ties in adults. METHODS: All patients who underwent tonsillectomy from July 2012 to September 2016 were retrospectively reviewed. Intraoperative and postoperative bleeding, pain, and return to normal food intake were compared between patients who underwent coblation tonsillectomy and those who underwent coblation tonsillectomy with ties. RESULTS: Of 515 patients, 300 (58.3%) underwent coblation tonsillectomy and 215 (41.7%) underwent coblation tonsillectomy with ties. Twenty-five (4.9%) patients developed postoperative hemorrhage, 22 (88.0%) of whom had undergone coblation tonsillectomy and 3 (12.0%) of whom had undergone coblation tonsillectomy with ties. Patients who underwent coblation tonsillectomy reported less pain than those who underwent coblation tonsillectomy with ties. Patients who underwent coblation tonsillectomy with ties resumed a normal diet significantly later than those who underwent coblation tonsillectomy (10.0 ± 3.2 vs. 8.2 ± 1.9 days, respectively). CONCLUSION: Coblation tonsillectomy is associated with less intraoperative bleeding, a shorter surgery time, less postoperative pain, and fewer days to recovery of a normal diet than is coblation tonsillectomy with ties. However, coblation tonsillectomy with ties is associated with remarkably reduced postoperative hemorrhage.
