#10-Year Challenge: Local anaesthetic for post-tonsillectomy pain: Update meta-analysis

Is Laser Better than Cold Steel (Dissection and Snare) for Tonsillectomy?

OBJECTIVE

To analyse the surgical outcome of CO2 laser assisted tonsillectomy with the cold steel (conventional dissection and snare) tonsillectomy.

MATERIALS AND METHODS

This prospective, non-randomised, single blind study was conducted in 25 cases suffering with recurrent tonsillitis. The left tonsillectomy was performed with CO2 laser while the right tonsil was excised using cold steel method (conventional dissection and snare method). The surgical time, blood loss and post-operative pain for each method was recorded and analysed.

RESULTS

CO2 laser tonsillectomy had highly significant less intra-operative blood loss (41.8ml vs. 78.8ml with p = 0.001) and postoperative pain levels on postoperative day 1,3, and 5 ( p value of 0.013, 0.006 and 0.000 respectively) as compared to cold steel method. However; there was no statistically significant difference in operative time between the two techniques (p > 0.05).

CONCLUSION

CO2 laser tonsillectomy appeared to be better technique than cold steel in terms of intra-operative haemorrhage and pain.

Reducing post-tonsillectomy haemorrhage: a multicentre quality improvement programme incorporating video-based cold technique instruction

OBJECTIVE

Data from the Norwegian Tonsil Surgery Register (NTSR) showed large differences between the hospitals in Norway in the readmission rate due to post-tonsillectomy haemorrhage (rrPTH; range, 0%-25%; national average, 8%). Because of these large variations in the rrPTH, we conducted a quality improvement project involving hospitals with good and bad readmission rates.

METHODS

Seven hospitals with readmission rates greater than 10% and four with rates lower than 5% participated in this project. We recorded videos of ear, nose and throat surgeons from the hospitals with low readmission rates when they performed extracapsular tonsillectomy, and these videos of cold dissection tonsillectomy were used as teaching material for examples of good surgical skills for the other hospitals. After a 2-day workshop, all participants from the hospitals went back to their institutions and prepared local plans to improve their results. We used the Plan-Do-Study-Act model. The primary outcome variable was the patient-reported rrPTH in the NTSR. As secondary goal, we aimed to identify aspects of the tonsillectomy procedure that could help achieve a lower rrPTH.

RESULTS

The participating hospitals reduced their rrPTH from 18% at baseline (2017/2018) to 7% in 2020. Six of seven hospitals changed their dissection technique significantly to more use of cold dissection.

CONCLUSION

By learning cold dissection tonsillectomy from surgeons with low rrPTH, it seems possible to decrease the rates of bleeding complications after tonsillectomy. A combination of videos as a teaching tool, new treatment plans, and focus on quality and improvement may effectively improve surgical results. The videos can show details that are difficult to convey in the literature. Quality registers can be used to identify areas requiring improvement and evaluate the effects of changes in practice.
