Comparison of Histopathological Healing Outcome between Dissection Ligation and Electrocautery Technique of Tonsillectomy

Abstract

Background: Various techniques are available for tonsillectomy. Selection of the technique is based on the duration of surgery, intraoperative blood loss, post operative pain, duration and healing pattern of the tonsillar fossa. Objective: To compare the outcome of better healing pattern in dissection ligation technique and electrocautery technique of tonsillectomy. Study Design: Randomized control trial. Settings: ENT Department, Mayo Hospital Lahore Pakistan. Duration: Two years from December 01, 2019 to November 30, 2021. Methods: 106 patients with symptoms of recurrent attacks of sore throat with fever, obstructive sleep apnea, pain and difficulty in swallowing were included. Patients were randomized into two groups by random number table. Group A was operated by dissection-ligation technique and group B was operated by electrocautery technique. On 7^th post tonsillectomy day healing score was calculated by taking tissue sample for histopathology from the tonsillar fossa. Results: Mean age of patients in group A was 14.59 ± 2.23 and in group B was 12.29 ± 2.09 years. In group A there were 55% males and 45% females while in group B 60% and 40% respectively. Statistically significant difference were found in terms of profound inflammation, formation of abundant granulation tissue and collagen fibers reticular pattern between two groups on histopathology. Conclusion: Healing outcomes are better in dissection ligation technique than electrocautery technique of tonsillectomy.
