Carbon footprints of various subtotal tonsillectomy techniques

Abstract

Objectives: The aim of the present study was to assess greenhouse gas emissions for the main current subtotal tonsillectomy techniques.

Materials and methods: A retrospective study was conducted in 2 French university hospital pediatric ENT departments in 2022. The target techniques were radiofrequency with single-use or reusable needle, coblation, and dissection by cold instruments or by bipolar forceps. The medical devices required by each technique were listed and respective greenhouse gas emissions (carbon footprint, in kg eCO₂) were calculated, according to weight, energy consumption and place of production.

Results: Coblation generated a carbon footprint of 8.6kg eCO₂, versus 0.1-0.2kg eCO₂ for the other techniques.

Conclusion: Greenhouse gas emissions in subtotal tonsillectomy differ greatly according to technique. Bipolar dissection and radiofrequency have a smaller footprint than coblation. This type of data, which needs to be weighed over time according to medical benefit, should be systematically taken into account in choosing hardware for surgery.
