Microscopic Partial Tonsillectomy / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Conventional tonsillectomy with the naked eye has posed problems in obtaining a good surgical field and in minimizing damage to the adjacent tissue. Tonsillectomy using an operating microscope offers outstanding illumination and visualization of the surgical field, thereby reducing the incidence of complications associated with tonsillectomy. The objective of this study was to compare the surgical methods of the conventional and the microscopic tonsillectomies, and to evaluate the usefulness and effectiveness of the microscopic tonsillectomy. MATERIALS AND METHODS: Two hundred children between the ages of five and ten who received tonsillectomy between June 1995 and August 1998 at Korea University Hospital were divided into two groups,' one group underwent tonsillectomy using an operating microscope (Group 1, n=100) and the other group underwent tonsillectomy using the conventional dissection and snare technique (Group 2, n = 100). Duration of surgery, post-operative healing period, amount of intra and post-operative hemorrhage, post- operative pain score, and the incidence of post-operative cicatrical pharyngeal stenosis were compared between the two groups. RESULTS: There was no statistically significant diference in operating time and post-operative healing period between the two groups, but cicatrical pharyngeal stenosis due to post-operative scarring was more common in the group that underwent conventional tonsillectomy. The amount of hemorrhage both intra and post-operatively, and post-operative pain was significantly decreased in the microscopic tonsillectomy group. CONCLUSION: The widespread use of operating microscope in otolaryngological surgeries allows this technique to be applied to tonsillectomy with few problems. This technique affords decreased intra-operative bleeding, less post-operative complications, and decreased post-operative pain compared with conventional techniques. We believe that microscopic tonsillectomy is a safe, elegant and effective procedure that represents a new concept in tonsil surgery.
