Objective The Sonopet Ultrasonic Aspirator is FDA approved for use in surgical procedures where fragmentation, emulsification, and aspiration of tissue is desirable. 1 To date there have been no reports of its use in performing tonsillectomies. The purpose of this study was to determine if using a Sonopet ultrasonic aspirator to perform tonsillectomy in adults is feasible and to assess for postoperative outcomes and complications. Study Design A retrospective chart review. Setting Standalone surgery center Methods The charts of 50 consecutive patients over the age of 18 who underwent tonsillectomy utilizing the Sonopet ultrasonic aspirator by a single surgeon from May 1, 2021 to July 31, 2024 were retrospectively reviewed. Informed consent for tonsillectomy using a Sonopet ultrasonic aspirator was obtained for each patient. Preoperative demographic information and postoperative measures were assessed including visual analog scores for maximal VAS pain score from post-operative day ( POD) 1 to 7, number of days with pain score greater than 4, number of days out of work or school, and any complications up to 3 months postoperatively. Results The patients had an average of 4.8 ± 1.1 days with a VAS pain score greater than 4 and a maximal post-operative VAS pain score of 6.8±1.4 . Patients were able to return to work or school in 6.1 ± 0.9 days postop. Adverse events post-operatively were mild. There were no incidences of postoperative bleeding. Conclusion An ultrasonic aspirator is a viable alternative for performing tonsillectomy in adults that has the potential to decrease post-operative recovery and complications. A larger prospective randomized cohort study is warranted.
