BACKGROUND:Morbidity following tonsillectomy continues to be a major concern to parents, children, and physicians alike. Reduction in post-operative complications, optimal control of pain, and satisfactory return to a normal lifestyle are all important to both family and society. This study compares both the complication and recovery rates after microbipolar dissection (MBPD) technique of tonsillectomy to two well established tonsillectomy techniques: hot knife (HK) and cold knife/cautery (CK/C). METHODS: A total of 200 consecutive patients presenting for tonsillectomy by the first author (MP) were randomized to either undergo MBPD or HK tonsillectomy. Concurrently, an additional two hundred patients were randomized to undergo MBPD or CK/C tonsillectomy by the second author (LB). Patients were prospectively followed for complications including bleeding and dehydration and multiple indicators of recovery rate. RESULTS:Postoperative bleeding of any kind was significantly less in the MBPD group than in the CK/C and HK groups (5 vs 12.4 vs 12.5% (P<0.001). The need for post-operative intervention for bleeding, i.e. local control or return to the operating room, was also significantly less in the MBPD group. Return to normal activity occurred 2 days earlier in the MBPD group versus either CK/C or HK (P<0.001). Additionally, earlier recovery was reflected in fewer total doses of pain medication in the MBPD group. Operative time was 3-5 min longer for MBPD (24.2 min) than for CK/C or HK (21.1 and 16.5 min, respectively); blood loss was similar (within 15 cc) among all treatment groups. CONCLUSION:MBPD tonsillectomy compared most favorably to conventional techniques (CK/C and to HK tonsillectomy). Important clinical outcome differences included a lower bleed rate, earlier recovery and fewer days lost from work and school. The financial impact is estimated to be quite favorable. MBPD tonsillectomy is now our preferred method in children.
