Abstract
Objective:To evaluate efficacy and postoperative morbidity in tonsillectomy using the harmonic scalpel vs conventional electrocautery. Materials and Methods:1) We compared intra-operative bleeding and operation time and analyzed the degree of pain, oral feeding and the ability to return to normal activities from the questionnaire. 2) Animal study:Using rats, we made each linear wound with harmonic scalpel or electrocautery, then compare the width of thermal injury area with trichrome stain. Result:Harmonic scalpel tonsillectomy had significant advantages over electrocautery tonsillectomy in terms of post operative pain, oral diet tolerance and the time of return to normal life. In addition, it increased patients’ overall satisfaction with the surgery. In animal study, it was found that the thermal injury was less severe in the wound caused by harmonic scalpel than by electrocautery. Conclusion:Harmonic scalpel tonsillectomy decreases the thermal injury of the adjacent tissue, thus it has advantages over electrocautery in post tonsillectomy morbidity.
하모닉 스칼펠은 낮은 온도에서 작용하여 주변 조직에 열손상을 적게 주는 원리로 인해 수술 후 통증, 구강 섭취, 일상 생활로의 복귀에 기존의 전기 소작술에 비해 유의한 이점을 지니며 이를 바탕으로 수술에 대한 환자의 주관적 만족도를 높임을 확인할 수 있었다.
