Abstract
Review of literature revealed different techniques for tonsillectomy which have been studies thoroughly, but convincing evidence in literature is still lacking as far as the optimal method of performing this surgical procedure.
In this work, 250 patients with recurrent attacks of tonsillitis that indicate tonsillectomy, were divided into five equal groups. The first group underwent conventional tonsillectomy; second one underwent bipolar diathermy technique, third bipolar scissor technique, fourth laser technique, and fifth coblation tonsillectomy.
According to our statistical analysis and data, bipolar and laser techniques proved to be significantly better than the other tonsillectomy techniques regarding reduced intraoperative blood loss, and operative time which indirectly impacts the cost-effectiveness of this procedure. The mean intraoperative blood loss was 10.9 ml with the bipolar scissors, while with the laser technique it was 11.96 ml. Also, it has been found that the mean operative time was 10.18 minutes with the bipolar scissors, and it was 13 minutes with laser group.
Also, we found that coblation tonsillectomy has less postoperative pain, in contrast laser was associated with higher post-operative pain levels.
The disadvantages of laser that the pain level of patients in laser tonsillectomy was significantly higher at post-operative day seven. It showed a higher mean overall pain score of 7.82, if compared with 4.52 of the coblation technique. Also, the incidence of postoperative bleeding showed that no significant difference between all groups as regard post-tonsillectomy bleeding.
In our study, we concluded that bipolar scissors and laser is proved to be better and effective tool for operative time and blood loss during tonsillectomy, while coblation tonsillectomy is the best for less postoperative pain.
So, these criteria for different techniques of tonsillectomy should be discussed with patients or their parents (if they are children) to choose the most suitable technique for each patient taking into consideration the institutional available equipment’s.
