Abstract
Objectives
Learn the molecular resonance (MR) technology for tonsillectomy. An analysis of outcomes of MR compared to standard cold-knife (CK) and monopolar cautery (MPC) for pediatric tonsillectomy offers new possibilities, lowering postoperative morbidity.
Study Design
Eleven-year, prospective, randomized, 3-group trial.
Setting
Tertiary care pediatric institution.
Subjects and Methods
Eight hundred and seventy-three children undergoing adenotonsillectomy were randomly assigned to MR (n = 283), CK (n = 279), or MPC (n = 279) techniques. Outcome measures included intraoperative time, blood loss, postoperative pain, weight loss, and histopathologic examination on excised tonsils.
Results
Histopathologic evaluation revealed reduced thermal injury with MR over MPC (43 µm vs 186, P < .001), statistically associated with reduced muscular, blood vessel, and nerve fiber damage compared to CK (P < .001). Blood loss was minimal in MR. Significant reduced pain scores were related to MR (P < .002). Two MR, 15 CK, and 12 MPC patients experienced delayed bleeding.
Conclusion
MR for pediatric tonsillectomy resulted in reduced histopathologic thermal injury, lower pain scores, and reduced postoperative morbidity compared with CK and MPC techniques in an 11-year study.
