Final answer:
Swollen lips and eyes from burns are usually addressed with surgical reduction before embalming to better control swelling and potential complications, which helps to maintain desired appearance after embalming.
Step-by-step explanation:
In the case of swollen lips and eyes resulting from burns, surgical reduction would typically be performed before embalming. This is due to the fact that performing surgical procedures prior to embalming allows for better management of swelling and potential leakage issues that could be exacerbated by the embalming process. When the body is prepared beforehand, the chemicals used in embalming can help preserve the surgical interventions and contribute to a more desirable post-embalm appearance.
